description: Gynaikothrips microchaetus Ananthakrishnan and Jagadish (Figs 1–9)
Female macroptera. B ody colour mainly brown; femora brown, tarsi yellow; fore tibiae yellow with small brown area at base, mid and hind tibiae brown with distal one-third yellow; tarsi yellow; antennal segments I–II brown, III–VIII uniformly yellow (Fig. 3); pronotal epimeral setae pale to very weakly shaded. Head longer than wide; with two pairs of slender, pointed, po setae not reaching to compound eyes (Fig. 1); po setae vary in length 16–43 microns, and also vary in position such that they are not always in a simple transverse row; maxillary stylets about one-third of head width apart, retracted to base of postocular setae (Fig. 1). Antennal segmentation and sense cones typical of genus. Pronotum epimeral setae well developed, apex weakly expanded (Fig. 2), am setae minute (6–15 microns), aa, ml and pa variable in length (10–30 microns); notopleural sutures complete. Fore tarsal tooth small, directed forwards (Fig. 3). Fore wings parallelsided, with 14–20 duplicated cilia. Prosternal basantra absent; mesopresternum boat shaped; metathoracic sternopleural sutures absent. Pelta triangular (Fig. 4); tergites II–VII with 2 pairs of sigmoid wing-retaining setae (Fig. 7); tube length variable, anal setae shorter than tube (Fig. 6).
Measurements (lectotype female in microns). Body length 2545. Head, length 275; width 222; po, inner pair 30; outer pair 20. Pronotum, length 158; width 282; major setae—am 15, aa 20, pa 24, ml 25, epim 96. Mesonotum lateral setae 30. Fore wing, length 930; sub-basal wing setae 16, 18, 30. Tergite IX setae, S1 225; S2 244; S3 198. Tube, length 289; width—base 71; apex 41; anal setae 244.
Male macroptera. Similar to female in colour and structure but smaller, fore tarsal tooth very small. Sternite VIII fully occupied by pore plate (Fig. 9), also tergite VIII similarly occupied by this extensive pore plate except for a small triangle at median anterior margin (Fig. 8).
Measurements (paralectotype male in microns). Body length 2442. Head, length 258; width 208; po, inner pair 19; outer pair 19. Pronotum, length 146; width 273; major setae—am 16, aa 27, pa 22, ml 20, epim 84. Mesonotum lateral setae 34. Fore wing, length 860; sub-basal wing setae 10, 16, 26. Tergite IX setae, S1 181; S2 26; S3 225. Tube, length 235; width—base 70; apex 36; anal setae 213.
