Ixodidae 

We exclude the following names from our list of Ixodidae  :

(i) Amblyomma laticaudae Warburton, 1933  is considered valid in Camicas et al. (1998), Horak et al. (2002) and Barker and Murrell (2008); Guglielmone et al. (2009) do not include it in their list of controversial names, while Kolonin (2009) considers this name a synonym of Amblyomma nitidum Hirst and Hirst, 1910  . In fact, Keirans, in Voltzit and Keirans (2002), determined that the types of these taxa are conspecific. Therefore, we agree with Kolonin (2009) that A. laticaudae  is an invalid name.

(ii) Bothriocroton decorosum (Koch, 1867)  is included as a member of Aponomma  by Kolonin (2009), but this name is a synonym of B. undatum  , as explained in Santos Dias (1993).

(iii) Haemaphysalis vietnamensis Hoogstraal and Wilson, 1966  is included as a valid name in Kolonin (2009), but it is a synonym of H. colasbelcouri (Guglielmone et al. 2009)  .

(iv) Haemaphysalis xinjiangensis Teng, 1980  is not included as a valid species in Kolonin (2009). Teng and Jiang (1981) consider this name a synonym of H. danieli  , and we accept their decision, since the senior author also described H. xinjiangensis  .

(v) Hyalomma erythraeum Tonelli-Rondelli, 1932  is included as a valid name in Kolonin (2009), but it was convincingly shown to be a synonym of H. impeltatum  by Apanaskevich and Horak (2009).

(vi) Rhipicephalus hoogstraali Kolonin, 2009  was described on the Internet, contrary to the rules of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature, 2009, Articles 8.6 and 9.8), and is therefore a nomen nudum.

1. Amblyomma albolimbatum Neumann, 1907 

2. Amblyomma albopictum Neumann, 1899 

3. Amblyomma americanum (Linnaeus, 1758) 

4. Amblyomma antillorum Kohls, 1969 

5. Amblyomma arcanum Karsch, 1879  ( Aponomma  )

6. Amblyomma argentinae Neumann, 1905  . Guglielmone et al. (2003) stated that the year of description for A. argentinae  is 1904, but this is in error because Neumann recognized 1905 as the correct year. Previously, this species was incorrectly named A. testudinis (Guglielmone et al. 2009)  .

7. Amblyomma astrion Dönitz, 1909 

8. Amblyomma aureolatum (Pallas, 1772) 

9. Amblyomma auricularium (Conil, 1878) 

10. Amblyomma australiense Neumann, 1905  . See A. echidnae  .

11. Amblyomma babirussae Schulze, 1933 

12. Amblyomma beaurepairei Vogelsang and Santos Dias, 1953  . This species is close to A. inornatum  and A. auricularium  but is provisionally considered valid in Guglielmone et al. (2009). However, Kolonin (2009) considers it a synonym of A. auricularium  .

13. Amblyomma boeroi Nava, Mangold, Mastropaolo, Venzal, Oscherov and Guglielmone, 2009 

14. Amblyomma boulengeri Hirst and Hirst, 1910 

15. Amblyomma brasiliense  Aragão, 1908

16. Amblyomma breviscutatum Neumann, 1899  . Until recently, this species was known as A. cyprium Neumann, 1899 (Guglielmone et al. 2009)  , a name still considered valid in Kolonin (2009), who does not justify his position. However, Keirans, in Voltzit and Keirans (2002), determined, as had Santos Dias (1956) before him, that the types of A. cyprium  and A. breviscutatum  are conspecific and that the latter name has page priority.

17. Amblyomma cajennense (Fabricius, 1787)  . This is the type species of the genus Amblyomma  ; it was originally named Acarus cajennensis  . Beati, L. and Nava, S. (pers. comm.) believe that A. cajennense  comprises a complex of sibling species.

18. Amblyomma calabyi Roberts, 1963 

19. Amblyomma calcaratum Neumann, 1899 

20. Amblyomma chabaudi Rageau, 1964 

21. Amblyomma clypeolatum Neumann, 1899 

22. Amblyomma coelebs Neumann, 1899 

23. Amblyomma cohaerens Dönitz, 1909 

24. Amblyomma compressum (Macalister, 1872) 

25. Amblyomma cordiferum Neumann, 1899 

26. Amblyomma crassipes (Neumann, 1901)  ( Aponomma  ). This species is similar to A. fuscolineatum  but is provisionally considered valid because little material is available for examination and the types have not been compared (Guglielmone et al. 2009). Kolonin (2009), using the name Aponomma  , considers A. crassipes  invalid but does not include a comparison of types.

27. Amblyomma crassum Robinson, 1926 

28. Amblyomma crenatum Neumann, 1899 

29. Amblyomma cruciferum Neumann, 1901 

30. Amblyomma darwini Hirst and Hirst, 1910 

31. Amblyomma dissimile Koch, 1844  . Guglielmone et al. (2009) argue in favor of this name instead of A. bibroni (Gervais, 1842)  because of the confused history of the latter taxon.

32. Amblyomma dubitatum Neumann, 1899  . Until recently, this species was known as A. cooperi Nuttall and Warburton, 1908 (Guglielmone et al. 2009)  .

33. Amblyomma eburneum Gerstäcker, 1873 

34. Amblyomma echidnae Roberts, 1953  . This species is very similar to A. australiense  , but Guglielmone et al. (2009) consider A. echidnae  provisionally valid until its status can be clarified. Kolonin (2009) does not include this species in his list of the Ixodidae  of the world.

35. Amblyomma elaphense (Price, 1959)  ( Aponomma  ). See A. sphenodonti  .

36. Amblyomma exornatum Koch, 1844  ( Aponomma  )

37. Amblyomma extraoculatum Neumann, 1899  . See A. romitii  .

38. Amblyomma falsomarmoreum Tonelli-Rondelli, 1935 

39. Amblyomma fimbriatum Koch, 1844  ( Aponomma  )

40. Amblyomma flavomaculatum (Lucas, 1846)  ( Aponomma  ). See A. inopinatum  .

41. Amblyomma fulvum Neumann, 1899 

42. Amblyomma fuscolineatum (Lucas, 1847)  ( Aponomma  ). See A. crassipes  and A. varanense  .

43. Amblyomma fuscum Neumann, 1907  . A valid taxon ignored in some lists of ticks (Guglielmone et al. 2009).

44. Amblyomma geayi Neumann, 1899  . Guglielmone et al. (2009) discuss the lack of agreement concerning this name, because some authors regard A. geayi  as a synonym of A. perpunctatum (Packard, 1869)  . However, the description of the latter taxon is inadequate, and we therefore consider the name A. geayi  valid, pending type comparison.

45. Amblyomma gemma Dönitz, 1909 

46. Amblyomma geochelone Durden, Keirans and Smith, 2002 

47. Amblyomma geoemydae (Cantor, 1847) 

48. Amblyomma gervaisi (Lucas, 1847)  ( Aponomma  ). This is the type species of the genus Aponomma  ; it was originally named Ixodes gervaisii  .

49. Amblyomma glauerti Keirans, King and Sharrad, 1994 

50. Amblyomma goeldii Neumann, 1899 

51. Amblyomma hainanense Teng, 1981  . Kolonin (2009) considers A. hainanense  a synonym of A. helvolum  , but no comparison of types has been attempted. Therefore, we treat A. hainanense  as tentatively valid.

52. Amblyomma hebraeum Koch, 1844 

53. Amblyomma helvolum Koch, 1844 

54. Amblyomma hirtum Neumann, 1906 

55. Amblyomma humerale Koch, 1844 

56. Amblyomma imitator Kohls, 1958 

57. Amblyomma incisum Neumann, 1906  . See A. latepunctatum  .

58. Amblyomma inopinatum (Santos Dias, 1989)  ( Aponomma  ). This species is not included in Kolonin (2009), who appears to consider it a synonym of A. flavomaculatum  and places it in the genus Aponomma  .

59. Amblyomma inornatum (Banks, 1909) 

60. Amblyomma integrum Karsch, 1879 

61. Amblyomma javanense (Supino, 1897) 

62. Amblyomma komodoense (Oudemans, 1928)  ( Aponomma  )

63. Amblyomma kraneveldi (Anastos, 1956)  ( Aponomma  )

64. Amblyomma latepunctatum Tonelli-Rondelli, 1939  . This species was previously confused with A. incisum  and with A. scalpturatum (Guglielmone et al. 2009)  .

65. Amblyomma latum Koch, 1844  ( Aponomma  )

66. Amblyomma lepidum Dönitz, 1909 

67. Amblyomma limbatum Neumann, 1899 

68. Amblyomma loculosum Neumann, 1907 

69. Amblyomma longirostre (Koch, 1844) 

70. Amblyomma macfarlandi Keirans, Hoogstraal and Clifford, 1973 

71. Amblyomma macropi Roberts, 1953 

72. Amblyomma maculatum Koch, 1844 

73. Amblyomma marmoreum Koch, 1844 

74. Amblyomma moreliae (Koch, 1867) 

75. Amblyomma moyi Roberts, 1953 

76. Amblyomma multipunctum Neumann, 1899 

77. Amblyomma naponense (Packard, 1869) 

78. Amblyomma neumanni Ribaga, 1902  . Nava et al. (2009 a) state that the description by Voltzit (2007) of A. neumanni  actually applies to A. parvitarsum  .

79. Amblyomma nitidum Hirst and Hirst, 1910  . See paragraph “i” above our list of Ixodidae  .

80. Amblyomma nodosum Neumann, 1899 

81. Amblyomma nuttalli Dönitz, 1909 

82. Amblyomma oblongoguttatum Koch, 1844 

83. Amblyomma orlovi (Kolonin, 1992)  ( Aponomma  ). This species is considered tentatively valid in Guglielmone et al. (2009), who nonetheless strongly suggest that it is a synonym of A. transversale  . Guglielmone et al. (2009) err in listing the date of description as 1995.

84. Amblyomma ovale Koch, 1844 

85. Amblyomma pacae  Aragão, 1911

86. Amblyomma papuanum Hirst, 1914 

87. Amblyomma parkeri Fonseca  and Aragão, 1952. Kolonin (2009) expresses doubt about the status of this species, but Labruna et al. (2009 a) present sound evidence for its validity.

88. Amblyomma parvitarsum Neumann, 1901  . See A. neumanni  .

89. Amblyomma parvum  Aragão, 1908

90. Amblyomma pattoni (Neumann, 1910)  ( Aponomma  )

91. Amblyomma paulopunctatum Neumann, 1899 

92. Amblyomma pecarium Dunn, 1933 

93. Amblyomma personatum Neumann, 1901 

94. Amblyomma pictum Neumann, 1906 

95. Amblyomma pilosum Neumann, 1899 

96. Amblyomma pomposum Dönitz, 1909 

97. Amblyomma postoculatum Neumann, 1899 

98. Amblyomma pseudoconcolor  Aragão, 1908

99. Amblyomma pseudoparvum Guglielmone, Mangold and Keirans, 1990 

100. Amblyomma quadricavum (Schulze, 1941) 

101. Amblyomma rhinocerotis  (de Geer, 1778)

102. Amblyomma robinsoni Warburton, 1927 

103. Amblyomma romitii Tonelli-Rondelli, 1939  . This species was previously considered a synonym of A. extraoculatum (Guglielmone et al. 2009)  .

104. Amblyomma rotundatum Koch, 1844 

105. Amblyomma sabanerae Stoll, 1894 

106. Amblyomma scalpturatum Neumann, 1906  . See A. latepunctatum  .

107. Amblyomma scutatum Neumann, 1899 

108. Amblyomma soembawense (Anastos, 1956)  ( Aponomma  )

109. Amblyomma sparsum Neumann, 1899 

110. Amblyomma sphenodonti (Dumbleton, 1943)  ( Aponomma  ). Miller et al. (2007) believe that this species, and possibly A. elaphense  , should be classified in a genus other than Amblyomma  .

111. Amblyomma splendidum Giebel, 1877 

112. Amblyomma squamosum Kohls, 1953 

113. Amblyomma supinoi Neumann, 1904 

114. Amblyomma sylvaticum  (de Geer, 1778)

115. Amblyomma tapirellum Dunn, 1933 

116. Amblyomma testudinarium Koch, 1844 

117. Amblyomma tholloni Neumann, 1899 

118. Amblyomma tigrinum Koch, 1844 

119. Amblyomma torrei Pérez Vigueras, 1934 

120. Amblyomma transversale ( Lucas, 1845)  ( Aponomma  ). Most authors consider 1844 the year of description of A. transversale  , but the name Ixodes transversalis  in Lucas (1844) lacks a description (i.e., it is a nomen nudum), and this situation was amended in Lucas (1845). See A. orlovi  .

121. Amblyomma triguttatum Koch, 1844 

122. Amblyomma trimaculatum (Lucas, 1878)  ( Aponomma  )

123. Amblyomma triste Koch, 1844 

124. Amblyomma tuberculatum Marx, 1894 

125. Amblyomma usingeri Keirans, Hoogstraal and Clifford, 1973 

126. Amblyomma varanense (Supino, 1897)  ( Aponomma  ). Kolonin (2009) considers A. varanense  a synonym of A. fuscolineatum  (both are treated as species of Aponomma  ) but without presenting evidence. We believe A. varanense  to be valid.

127. Amblyomma variegatum (Fabricius, 1794) 

128. Amblyomma varium Koch, 1844 

129. Amblyomma vikirri Keirans, Bull and Duffield, 1996 

130. Amblyomma williamsi Banks, 1924 

1. Anomalohimalaya cricetuli Teng and Huang, 1981  . Deng et al. (1999) consider this species a synonym of A. lotozkyi  but without explanation. We therefore maintain the validity of A. cricetuli  . 2. Anomalohimalaya lamai Hoogstraal, Kaiser and Mitchell, 1970  . This is the type species of the genus Anomalohimalaya  .

3. Anomalohimalaya lotozkyi Filippova and Panova, 1978  . See A. cricetuli  .

1. Bothriocroton auruginans (Schulze, 1936)  ( Aponomma  )

2. Bothriocroton concolor (Neumann, 1899)  ( Aponomma  ). See B. oudemansi  .

3. Bothriocroton glebopalma (Keirans, King and Sharrad, 1994)  ( Aponomma  ). This is the type species of the genus Bothriocroton  , by original designation ( Klompen et al. 2002); it was originally named Aponomma glebopalma  .

4. Bothriocroton hydrosauri (Denny, 1843)  ( Aponomma  ). See B. tachyglossi  .

5. Bothriocroton oudemansi (Neumann, 1910)  ( Aponomma  ). This species was considered a synonym of B. concolor  , but there is now sound scientific evidence for its validity as a species (Guglielmone et al. 2009).

6. Bothriocroton tachyglossi (Roberts, 1953)  ( Aponomma  ). This species was considered a synonym of B. hydrosauri  , but there is now convincing evidence for its validity (Guglielmone et al. 2009).

7. Bothriocroton undatum (Fabricius, 1775)  ( Aponomma  ). This name is considered invalid by Kolonin (2009). See B. decorosum  , paragraph “ii” above our list of Ixodidae  .

1. Compluriscutula vetulum Poinar and Buckley, 2008  . This is the type species of the fossil genus Compluriscutula  . It is not included in the list of Kolonin (2009).

1. Cornupalpatum burmanicum Poinar and Brown, 2003  . This is the type species of the fossil genus Cornupalpatum  . It is not included in the list of Kolonin (2009).

2. Cosmiomma hippopotamensis (Denny, 1843)  . This is the type species of the monotypic genus Cosmiomma  . It was originally named Ixodes hippopotamensis  .

1. Dermacentor abaensis Teng, 1963  . This species is similar to D. everestianus  but is provisionally considered valid in Guglielmone et al. (2009) because there has been no definitive study to support this synonymy. One of us (DAA) is currently comparing the types of D. abaensis  , D. everestianus  and D. birulai Olenev, 1927  . Therefore, additional information on the specific status of these taxa should be forthcoming.

2. Dermacentor albipictus (Packard, 1869) 

3. Dermacentor andersoni Stiles, 1908 

4. Dermacentor asper Arthur, 1960  . Kolonin (2009) considers D. asper  a probable synonym of D. sinicus  but presents no evidence for this statement.

5. Dermacentor atrosignatus Neumann, 1906 

6. Dermacentor auratus Supino, 1897 

7. Dermacentor circumguttatus Neumann, 1897 

8. Dermacentor compactus Neumann, 1901 

9. Dermacentor confragus (Schulze, 1933)  . Originally spelled confractus, the name was later corrected to confragus  . The type specimens are currently being examined by one of us (TNP). We consider this name valid until studies of the type material permit a conclusive statement. Kolonin (2009) excludes this name from his list of ixodid ticks of the world.

10. Dermacentor dispar Cooley, 1937 

11. Dermacentor dissimilis, Cooley 1947 

12. Dermacentor everestianus Hirst, 1926  . See D. abaensis  .

13. Dermacentor halli McIntosh, 1931 

14. Dermacentor hunteri Bishopp, 1912 

15. Dermacentor imitans Warburton, 1933 

16. Dermacentor latus Cooley, 1937 

17. Dermacentor marginatus (Sulzer, 1776)  . See D. niveus  and D. ushakovae  .

18. Dermacentor montanus Filippova and Panova, 1974 

19. Dermacentor nitens Neumann, 1897  ( Anocentor  ). This is the type species of the genus Anocentor  .

20. Dermacentor niveus Neumann, 1897  . Kolonin (2009) lists this species as a synonym of D. daghestanicus Olenev, 1928  , but, in fact, the latter name is a junior synonym of D. niveus (Guglielmone et al. 2009)  . Estrada-Peña and Estrada-Peña (1991) examined part of the syntype series of D. niveus  (Cherestanek, Iran, ex Ovis aries  , 1882, loaned by Prof. P.-C. Morel), concluding that this species is conspecific with D. marginatus  , a view shared by Moshaverinia et al. (2009). A wider comparative study of D. marginatus  , D. niveus  and D. ushakovae  appears to be needed to further demonstrate the validity of these taxa. We consider D. niveus  provisionally valid while awaiting the results of this comparison. See also D. ushakovae  .

21. Dermacentor nuttalli Olenev, 1928 

22. Dermacentor occidentalis Marx, 1892 

23. Dermacentor parumapertus Neumann, 1901 

24. Dermacentor pavlovskyi Olenev, 1927 

25. Dermacentor pomerantzevi Serdjukova, 1951 

26. Dermacentor raskemensis Pomerantzev, 1946 

27. Dermacentor reticulatus (Fabricius, 1794)  . This is the type species of the genus Dermacentor  . It was originally named Acarus reticulatus  .

28. Dermacentor rhinocerinus (Denny, 1843) 

29. Dermacentor silvarum Olenev, 1931 

30. Dermacentor sinicus Schulze, 1932  . See D. asper  .

31. Dermacentor steini (Schulze, 1933) 

32. Dermacentor taiwanensis Sugimoto, 1935 

33. Dermacentor ushakovae Filippova and Panova, 1987  . Guglielmone et al. (2009) state that Camicas et al. (1998) consider D. ushakovae  a junior synonym of D. niveus  , while one of us (AEP) regards this species as a junior synonym of D. marginatus  . However, we have elected to recognize the validity of D. ushakovae  until type comparisons clarify its status. See also D. niveus  .

34. Dermacentor variabilis (Say, 1821) 

1. Haemaphysalis aborensis Warburton, 1913 

2. Haemaphysalis aciculifer Warburton, 1913 

3. Haemaphysalis aculeata Lavarra, 1904 

4. Haemaphysalis adleri Feldman-Muhsam, 1951 

5. Haemaphysalis anomala Warburton, 1913 

6. Haemaphysalis anomaloceraea Teng, 1984  . Guglielmone et al. (2009) state that Camicas et al. (1998) consider this species a synonym of H. shimoga  , but we continue to treat it as valid because there are no published grounds for synonymization. Kolonin (2009) considers both taxa ( H. anomaloceraea  and H. shimoga  ) to be synonyms of H. taiwana  but presents no justification for this position.

7. Haemaphysalis anoplos Hoogstraal, Uilenberg and Klein, 1967 

8. Haemaphysalis aponommoides Warburton, 1913 

9. Haemaphysalis asiatica (Supino, 1897)

25. Haemaphysalis celebensis Hoogstraal, Trapido and Kohls, 1965 

26. Haemaphysalis chordeilis (Packard, 1869) 

27. Haemaphysalis cinnabarina Koch, 1844  . This species is not included in Kolonin ´s (2009) list of ixodid ticks.

28. Haemaphysalis colasbelcouri (Santos Dias, 1958)  . Originally named Aponomma colasbelcouri Santos Dias, 1958  , this species is the senior synonym of H. vietnamensis  (see H. vietnamensis  , paragraph “iii” above our list of Ixodidae  ) (Guglielmone et al. 2009).

29. Haemaphysalis colesbergensis Apanaskevich and Horak, 2008  . This species is not included in Kolonin ´s (2009) list of ixodid ticks.

30. Haemaphysalis concinna Koch, 1844  . This is the type species of the genus Haemaphysalis  . See also H. filippovae  .

35. Haemaphysalis dangi Phan Trong, 1977 

36. Haemaphysalis danieli  Č erný and Hoogstraal, 1977. See paragraph “iv” above our list of Ixodidae  . Kolonin (2009) considers specimens of this taxon from China a synonym of H. pospelovashtromae  but provides no supporting evidence.

37. Haemaphysalis darjeeling Hoogstraal and Dhanda, 1970

7. Hyalomma dromedarii Koch, 1844  . This is the type species of the genus Hyalomma  in Camicas et al. (1998), but we agree with Filippova (1984), who considers H. aegyptium  to be the type.

8. Hyalomma excavatum Koch, 1844  . This species was previously classified as a subspecies of H. anatolicum (Guglielmone et al. 2009)  .

23. Hyalomma schulzei Olenev, 1931 

24. Hyalomma scupense Schulze, 1919  . Until recently, this species was known as H. detritum Schulze, 1919  by many Western workers. Because this is an economically important tick, Guglielmone et al. (2009) proposed referring to it as H. scupense  (= H. detritum  ) in order to avoid confusion.

27. Hyalomma turanicum Pomerantzev, 1946  . This species was previously classified as a subspecies of H. marginatum (Guglielmone et al. 2009)  . Kolonin (2009) excludes H. turanicum  from his list of ixodid ticks of the world.

1. Ixodes abrocomae Lahille, 1916  . Some authors have listed the year 1916 for Lahille ´s original description of Ixodes abrocomae  , while others have used the year 1917. An inquiry to the U.S Library of Congress failed to resolve the problem. A request to the Sociedad Chilena de Biología (publisher of Revista Chilena de Historia Natural, where the description of I. abrocomae  appeared) was not answered. We consider 1916 as the year of description of I. abrocomae  . See also I. sigelos  .

28. Ixodes berlesei Birula, 1895 

29. Ixodes bivari Santos Dias, 1990  . Kolonin (2009) does not include I. bivari  in his list; apparently he regards this name as a synonym of I. ventalloi  . One of us (AEP) examined the types of I. bivari  and found that they differ from I. ventalloi  , especially in the morphology of the basis capituli. Therefore, we treat I. bivari  as valid.

30. Ixodes boliviensis Neumann, 1904  . This species is very similar to I. diversifossus  , but Guglielmone et al. (2009) consider it valid pending a comparison of types.

37. Ixodes canisuga Johnston, 1849  . Teng and Jiang (1991) and Kolonin (2009) consider I. canisuga  a synonym of I. crenulatus  but provide no supporting evidence; we therefore have retained I. canisuga  as valid.

81. Ixodes filippovae  Č erný, 1961. Kolonin (2009) does not include this species in his list of ixodid ticks of the world. He is probably following Filippova (1977), who considers I. filippovae  a synonym of I. crenulatus  . In fact, the status of I. filippovae  is questionable and we list this species as provisionally valid while awaiting further studies.

199. Ixodes sigelos Keirans, Clifford and Corwin, 1976  . In Camicas et al. (1998), I. sigelos  is listed as a synonym of I. abrocomae Lahille, 1916  , but Guglielmone et al. (2009) found no evidence for this arrangement and declared both names valid. Recently, Guglielmone et al. (in press) redescribed the male and described the female of I. abrocomae  , thereby settling this controversy.

243. Ixodes zairensis Keirans, Clifford and Walker, 1982  1. Nosomma monstrosum (Nuttall and Warburton, 1908)  . This is the type species of the formerly monotypic genus Nosomma  ; it was originally named Hyalomma monstrosum  .

2. Nosomma keralensis Prakasan and Ramani, 2007  . The original description of this species is very poor and we strongly doubt its validity (Guglielmone et al. 2009), but we include it here pending type comparison with N. monstrosum  , which should readily clarify its status. Kolonin (2009) does not include this species in his list of the Ixodidae  of the world.

6. Rhipicephalus aurantiacus Neumann, 1907  . Guglielmone et al. (2009) note that this tick is considered a synonym of R. ziemanni  by some authors, but because there has been no comparison of types, we provisionally regard R. aurantiacus  as valid. Kolonin (2009) does not include R. aurantiacus  in his list of world Ixodidae  .

46. Rhipicephalus microplus ( Canestrini, 1888)  ( Boophilus  ). Some authors have listed the year 1887 for the original description of Rhipicephalus microplus  (the species was described as Haemophysalis [sic] micropla  ), while others have used the year 1888. An inquiry to the U.S. Library of Congress has shown that Canestrini (1887) was actually published in Padova by Stabilimento Prosperini in 1888; therefore, we recognize the latter year for the description of R. microplus  . A recent study by Labruna et al. (2009 b) presents evidence that populations of R. microplus  from Australia are not conspecific with Afrotropical and Neotropical populations, although Afrotropical and Neotropical populations are conspecific.

77. Rhipicephalus tricuspis Dönitz, 1906 

78. Rhipicephalus turanicus Pomerantzev, 1940  . While most Western workers list the year 1936 for the original description of R. turanicus  , we follow Filippova (1997), who considers 1940 to be the correct year.
