Odontothrips moritzi


Odontothrips moritzi  sp.n.

Female macroptera. Body dark brown ( Fig.1View FIGURES 1–7); all tarsi, fore tibia, antennal segments III–V, VIII and fore wing yellow, antennal segment VII shaded ( Fig.3View FIGURES 1–7), major body setae brown. Head about 1.1 times as broad as long, with transverse lines of sculpture, three pairs of ocellar setae present; ocellar III longer than other setae on head, arising on ocellar triangle margin and situated between hind and fore ocelli, 5 pairs of postocular setae arranged in a row, almost equal in length ( Fig. 2View FIGURES 1–7). Eyes with 5 pigmented facets. Mouth cone rounded. Antennae 8–segmented, segment I with pair of median dorso-apical setae; antennal segment VI with base of sensorium more than 0.7 as long as total length of this sensorium ( Fig. 4View FIGURES 1–7). Fore tibia without claw-like processes at apex; fore tarsus without tubercles on inner margin ( Fig. 6View FIGURES 1–7). Metanotum with campaniform sensilla arising medially ( Fig. 10View FIGURES 8–13). Fore wing first vein with setal row comprising about 4 setae at base, then 11–12 setae, then 2 setae near apex; second vein with complete row of setae ( Fig. 8View FIGURES 8–13); clavus with 5 marginal and one discal setae, terminal seta longer than subapical; 2 pairs of posteroangular setae, inner setae slightly longer than outer. Abdominal tergum I with transversely reticulate sculpture ( Fig. 10View FIGURES 8–13); tergites IV–VIII with no sculpture mesad of setal pair S2 ( Fig. 13View FIGURES 8–13); VIII with irregular group of microtrichia anterolateral to each spiracle, posteromarginal comb only present laterally; IX with two pairs of campaniform sensilla ( Fig. 12View FIGURES 8–13); median split on X short. Sternites without craspeda and discal setae; II with two pairs of posteromarginal setae, III–VII with three. Sternite VII setal pair S1 arise in front of margin, S2 and S3 arise at margin ( Fig. 11View FIGURES 8–13).

Measurements (holotype female in microns). Body length 1570. Head, length 123; width across eyes 133. Ocellar setae III length 57. Pronotum, length 130, maximum width 193; posteroangular setae length outer 50, inner 58. Metanotum median setae length 44. Fore wing, length 730. Abdominal tergum IV median setae length 11; tergum IX S1 100, S2 110; tergum X setae length 100. Antennal segments III–VIII length 55, 48, 33, 50, 13, 19; sensorium on antennal VI length 25, length of base 18.

Male not known.

Specimens examined. Holotype female, Iran, Fars province, Sepidan, Tang-e-Tizab , from flowers of an unidentified Fabaceae  , 18.vii.2015 (Mahsa Hakimara), in Natural History Museum, London, United Kingdom. 

Paratypes: 2 females, collected with holotype; paratypes deposited in Plant Protection Department , Shiraz University, Shiraz, Iran  .

Etymology. This new species is named after Professor Gerald Moritz, Department of Developmental Biology, Martin-Luther-University Halle-Wittenberg, Germany.

Comments. In the key by Pitkin (1972) this new species runs to O. elbaensis  and O. phlomidinus  in couplet 20, but is distinct from both of these species. It differs from both in having antennal segments III–V and VII–VIII yellow, whereas the other two species have only antennal segment III yellow. Moreover, the fore wing is uniformly yellow whereas it is shaded at the extreme apex in O. elbaensis  and O. phlomidinus  . The new species is further distinguished from O. elbaensis  by the absence of sculpture on the pronotum and abdominal tergites II–VIII, whereas this sculpture is present in O. elbaensis  (although absent in O. phlomidinus  ). However, O. moritzi  differs from O. phlomidinus  in the length of setae S1 and S2 on abdominal segment IX. Priesner (1954) gave the length of these setae in O. phlomidinus  as 155–173 and 172–190, whereas as indicated above in O. moritzi  they are around 100 microns.
