description: Stenchaetothrips martini sp. n.
Female macroptera. Body generally brown, with head and thorax slightly paler than abdomen (particularly after clearing for slide-mounting); legs mainly yellow but all femora weakly shaded with light brown; major setae brown; antennae mainly brown but III almost yellow; eyes with no pigmented facets; fore wing pale in basal fourth, then light brown but often again paler near apex. Antennae 7-segmented (Fig. 1), segment I with no dorsoapical setae; II with microtrichia on dorsal sculpture lines; III and IV with apices slightly narrowed, each bearing a short forked sense cone. Head slightly wider than long, cheeks rounded; ocellar setae III scarcely as long as distance between posterior ocelli, arising just outside anterior margins of triangle (Fig. 2); ocellar setae II and postocular setae III sub-equal, both longer than postocular setae I; setae II and IV shorter than V; ventral eye facets slightly larger than dorsal facets. Pronotum with transverse lines of sculpture (Fig. 2), 2 pairs of long posteroangular setae, 3 pairs of posteromarginal setae. Mesonotal campaniform sensilla present (Fig. 3), median setal pair in front of posterior margin. Metanotum closely striate, median setal pair not at anterior margin, paired campaniform sensilla present (Fig. 3). Fore wing first vein with 3 distal setae; second vein with 10–14 setae; clavus with 5 veinal and one discal seta. Prosternal ferna complete medially (Fig. 6); mesofurca with spinula usually prominent but sometimes weak, metafurca with no spinula. Hind coxa upper surface with 5 to 10 microtrichia on sculpture lines (Fig. 5). Tergite II with 4 lateral marginal setae (Fig. 4) (anterior seta sometimes reduced); tergites usually with a weak sculpture line between median setal pair, but no lines posterior to this; posterolateral margins of tergites with 1–4 variably weak triangular craspedal microtrichia (Fig. 4); V–VIII with paired ctenidia, on VIII posteromesad to the spiracle; VIII with complete comb (Fig. 7); IX with 2 pairs of campaniform sensilla, median dorsal setae stout, usually extending to or even beyond posterior margin. Sternites and pleurotergites with no discal setae; sternite II with 2 pairs of posteromarginal setae, III–VII with 3 pairs, median pair on VII arising in front of margin; sternite I with two minute setae on anterior margin, sternite II with three pairs of minute setae on anterior half (Fig. 5).
Measurements (holotype female in microns). Body length 1220. Head, length 115; width across cheeks 120; ocellar setae II 37; III 20; postocular setae I 20; II 12; III 37; IV 12; V 20. Pronotum, length 129; width 160; posteroangular setae 60. Fore wing length 700. Antennal segments III–VII length 50, 47, 37, 50, 18.
Male macroptera. Body, legs and antennal segments I–III mainly yellow, head with ocellar region light brown, abdominal segments IV–VII increasingly brown medially, VIII–IX uniformly brown (Fig. 8); mesofurcal spinula present but sometimes weak; metanotum with paired campaniform sensilla; tergal posterior margins smooth, without tooth-like lobes, VIII with comb represented by a few and variable number of short microtrichia (Fig. 8); IX with transverse row of 4 setae, anterior paired campaniform sensilla present or absent; sternites III–VII with transverse pore plates (Fig. 9) that are more than 0.5 of the sternite width.
Measurements (male paratype in microns). Body length 1050. Head, length 95; width across cheeks 115. Fore wing 600. Sternite IV pore plate width 75. Antennal segments III–VII length 47, 45, 35, 47, 15.
