GANTHELA JIANENSIS XU, KUNTNER & CHEN SP. NOV. ( FIG. 5 )

Holotype

Female (XUX-2013-534), Mount Qingyuan, Ji’an City, Jiangxi Province, China, 27.06°N, 115.05°E, 100 m a.s.l., 23 October 2013, collected by F.X. Liu, X. Xu, and Z. T. Zhang.

Paratypes

Ten females (XUX-2013-530-531/533–536/538-541A) collected at the same locality, 23 October 2013, collected by F.X. Liu, X. Xu, and Z. T. Zhang. No male found.

Etymology

‘Jian’ refers to the type locality of this species.

Diagnosis

Females of G. jianensis sp. nov. differ from other species of Ganthela by details in genitalia, with short and thick genital stalks ( Fig. 5B, C ), and by the slightly curved posterior part of the genital area ( Fig. 5B, C ). Ganthela jianensis sp. nov. differs from all other Ganthela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: G (59), A (131), A (155), C (245), T (249), G (317), C (398), C (528), C (581), and C (638).

Description

Female (holotype) ( Fig. 5A ). Carapace and opisthosoma, dark brown; chelicerae robust, with promargin of cheliceral groove with between ten and 13 strong denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites, with tergite 5 being largest; seven spinnerets. Measurements: BL 11.80 – 15.50 , CL 5.60 – 7.40 , CW 5.30 – 6.50 , OL 5.95 – 9.10 , and OW 4.46 – 6.70 ; ALE > PLE > PME > AME; palp 11.55 (4.00 + 2.10 + 2.45 + 3.00), leg I 13.25 (4.15 + 2.50 + 2.35 + 2.65 + 1.60), leg II 12.88 (3.73 + 2.37 + 2.25 + 2.75 + 1.78), leg III 13.82 11 December 2012, collected by D. Li, F.X. Liu, M. Kuntner, and X. Xu.

Paratypes

Three females [XUX-2012-(287/290/297)] collected at the same locality, 11 December 2012; eight females [XUX- 2013-(138–142/146A-148)] collected at the same locality, 9 July 2013; collected by F.X. Liu, X. Xu , and Z. T. Zhang.

Etymology

‘Qingyuan’ refers to the type locality of this species, Mount Qingyuan.

Diagnosis

Males of G. qingyuanensis sp. nov. differ from G. yundingensis by anatomical details in the palps, which have a small posterior apophysis on the conductor, in addition to the spiniform apex ( Fig. 6G ). Females of G. qingyuanensis sp. nov. can be distinguished from all other Ganthela species by details in the genitalia, with longer genital stalks ( Fig. 6B, C ). Ganthela qingyuanensis sp. nov. differs from all other Ganthela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: C (42), C (50), C (104), G (108), C (158), G (197), C (218), A (269), C (380), G (339), C (353), C (383), C (449), C (504), C (575), and C (625).

(4.00 + 2.42 + 2.17 + 3.23 + 2.00), and leg IV 20.37 (5.61 + 3.00 + 3.45 + 5.53 + 2.78).

Female genitalia

Posterior part of genital area slightly curved ( Fig. 5B, C ), with pair of receptacular clusters close to each other, and with very short and thick genital stalks ( Fig. 5B, C ).

Distribution

Jiangxi (Ji’an) Province, China
