Craspedothrips poecilus sp.n.

( Figs 24, 25 )

Female macroptera. Body bicoloured; head, pronotum and legs yellow, light brown anterolaterally on pterothorax also meso and metanota; abdominal tergites II–VIII light brown but sharply yellow postero-laterally, IX–X light brown; fore wing shaded including clavus but wing apex slightly paler; antennal segments I–II light brown, III almost yellow, IV brown with narrowed apex paler, V–VIII brown shading to light brown; major setae pale.

Head wider than long, cheeks straight; ocellar setae pair I small, arising close together, II just anterior to ocellar triangle lateral to first ocellus, III arise on tangent between anterior margins of posterior ocelli; postocular setae all small; ocellar triangle with no sculpture, posterior part of vertex with 5 or 6 transverse striae; frons with 6 pairs of prominent setae; compound eyes with no pigmented facets; maxillary palps 3-segmented. Antennal segment I with paired dorso-apical setae; II with no microtrichia, III–VI with microtrichia present; III–IV with apex elongate, greatly so on IV, both with long forked sensoria; inner and outer lateral sensoria on V flattened; VI with 3 sensoria; VIII longer than VII.

Pronotum with prominent striae forming transverse reticulation, posterior submarginal area demarcated; 2 pairs of postero-angular setae, 2 pairs of postero-marginal setae. Mesonotum transversely striate, anterior campaniform sensilla absent, median setal pair close to posterior margin. Metanotum irregularly reticulate, reticulation almost concentric on posterior; median setae close to lateral pair; campaniform sensilla present. Prosternal ferna slightly separated medially; mesothoracic sternopleural sutures complete; metapre-episternum band-like bearing one seta.

Abdominal tergites without craspedum; I transversely striate/reticulate, anterior half of II–VII with similar transverse lines medially and laterally; VIII with a few microtrichia in a short row terminating at spiracle; IX with one pair of campaniform sensilla, median dorsal setae long and extending beyond posterior margin; X short with weak split.

Sternites without craspedum, II with 3 pairs of minute setae near anterior margin and 2 pairs of posteromarginal setae; III–VII with 3 pairs of posteromarginal setae, on VII S1 and S2 arise well in front of margin.

Measurements (holotype female in microns). Body length 1350. Head, length 100; width 135; ocellar setae pair III 35. Pronotum, length 95; width 165; posteroangular setae—inner 55, outer 70; separation between pronotal striae medially 3–6. Fore wing length 820. Antennal segments III–VIII length, 52, 75, 50, 70, 12, 25.

Specimens studied. Holotype female, KENYA, Western District, Kakamega Forest , at 1620m, no host data, 4.iii.2007 (S. Okajima), in NMK . Paratypes, 1 female collected with holotype, in LETUA , 2 females with similar data except 3.iii.2007, in LETUA and NMK .

Comments. Collected quite close to the original site of antennatus , these two species are closely related. The new species is bicoloured, with the tergal sculpture particularly distinctive, the sculptured lines on the pronotum and metanotum much less closely spaced, and the major sensoria on the antennae more slender.
