The genus Neohydatothrips (Thysanoptera: Thripidae) in Iran with one new species and first record of a micropterous form Author Minaei, Kambiz text Zootaxa 2016 4189 2 367 377 journal article 10.11646/zootaxa.4189.2.10 cda4b1b3-6b0b-42e3-b83b-fcae7a69ac53 1175-5326 165954 72077B77-3A72-4CB4-ACC3-76C1BCDEABEB Neohydatothrips gracilicornis (Williams) ( Figs 20–26 ) Sericothrips gracilicornis Williams, 1916 : 222 . This species was described from England , with one synonym from Japan , and was recorded from clover ( Fabaceae ) and meadow grasses ( Poaceae ) ( Williams 1916 , Ishida 1931 ). It is known from various parts of Europe, China and Morocco , mainly from Vicia spp. ( Yang et al . 1993 , zur Strassen 2003). In Iran , N. gracilicornis is reported from several provinces on various plants including lucerne ( Mortazawiha & Dern 1977 , Alavi & Kamali 2003 , Fekrat & Manzari 2014 ). However it seems likely that the species occurs only in northern parts of this country. Female macroptera . Body dark brown, fore femur paler on apical fourth, fore tibia brownish yellow. Fore wing dark brown with sub-basal pale band, clavus yellow at apex; antennal segment I brown basally, yellow apically, II yellow, III shaded, remaining segments brown ( Fig. 20 ). FIGURES 14–19 . Neohydatothrips amygdali (14) Female; (15) Head and pronotum; (16) Meso and metanotum; (17) Abdominal tergites VII-X; (18) Metasternum; (19) Fore wing. FIGURES 20–26 . Neohydatothrips gracilicornis . (20) Female; (21) Male; (22) Head and pronotum; (23) Meso and metanotum; (24) Metasternum; (25) Sternites V–VI; (26) Sternites IV–VII (male). Head transversely striate ( Fig. 22 ), mouth cone long, extending between fore coxae; occipital apodeme close to but not confluent with posterior margin of eyes; ocellar triangle weakly and irregularly reticulate; ocellar setae III in ocellar triangle. Pronotum with transversely anastomosing striae; mesonotum with transverse striations. Metanotum with linear reticulation ( Fig. 23 ). Metasternal anterior margin almost straight ( Fig. 24 ). Fore wing second vein with 1 seta. Posterior margins of abdominal tergites with craspedum; tergites II–VI with no marginal comb medially, VII–VIII with comb medially; tergite IX with 2 pairs of mid-dorsal setae; sternites II–VI with craspedum ( Fig. 25 ). Measurements . (one female in microns): Body length 1375. Head length (width) 120 (170), ocellar setae III length 34. Pronotum length (width) 140 (220). Fore wing length 890. Antennal segments III–VIII length 62, 58, 41, 52, 10, 13. Male macroptera. Similar to female but smaller, sternites IV–VII with small oval pore plate ( Fig. 26 ). Measurements . (one male in microns): Body length 1140. Head length (width) 120 (164), ocellar setae III length?. Pronotum length (width) 107 (197). Fore wing length 720. Antennal segments III–VIII length 32, 29, 20, 50, 9, 12. Material studied . IRAN , East Azerbaijan province , Sarab , 1 male , on Populus sp., 11.vii.2004 ; Maragheh , 1 male , 1 female , on Medicago sativa , 10.vii.2005 ( S. A. A. Fathi ). Comments . This species is distinct among Neohydatothrips species because of its dark brown body colour, the presence of 1 seta on the fore wing second vein and the posterior margins of abdominal tergites that bear a craspedum.
