Craspedothrips nyanzai sp.n.

( Figs 22, 23 )

Female macroptera. Body and legs brown, tarsi yellow; major setae dark brown; fore wing shaded slightly paler at base, clavus also paler distally; antennal segment III mainly yellow, IV yellow in basal half, V–VIII brown.

Head wider than long, cheeks straight, mouth cone extending between fore coxae (head tilted down in available specimens); ocellar setae pair I small, close together, II just anterior to ocellar triangle, III arise on tangent between anterior margins of posterior ocelli; postocular setae all small; ocellar triangle with no sculpture; postocular part of vertex narrow with 3 or 4 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; III–IV with short and stout forked sensoria, apex of IV slightly elongate; lateral sensoria on V small and flattened; VI with 3 sensoria, external sensorium short; VIII long than VII.

Pronotum with irregular, widely spaced transverse striae, discal setae small, posterior submarginal area scarcely demarcated; 2 pairs of short postero-angular setae with inner pair stout, 3 pairs of postero-marginal setae. Mesonotum transversely striate, anterior campaniform sensilla present, median setal pair close to posterior margin. Metanotum irregularly reticulate; median setae short, not close to lateral pair; campaniform sensilla present. Prosternal ferna slightly separated medially; mesothoracic sternopleural sutures complete; metapre-episternum band-like bearing one small seta.

Abdominal tergites I–II and anterior half of III transversely sculptured, IV–VII with sculpture lines not extending to median setae and campaniform sensilla; I with no craspedum; II–VIII with broad band-like craspedum; VIII with ctenidium-like row of microtrichia terminating at spiracle; IX with two pairs of campaniform sensilla, median dorsal setae stout; X short with weak split.

Sternites II–VI with broad craspedum lobed between major setae, absent medially on VII; II with 3 pairs of minute setae near anterior margin; II with 2 pairs of posteromarginal setae, III–VII with 3 pairs, on VII S1 arises well in front of margin, S2 arises at margin.

Measurements (holotype female in microns). Body length 1220. Head, length 55; width 115; ocellar setae pair III 25. Pronotum, length 130; width 150; posteroangular setae – inner?40, outer 50; separation between pronotal striae medially 7-10. Fore wing length 610. Antennal segments III–VIII length, 35, 45, 33, 45, 10, 18.

Specimens studied. Holotype female, KENYA, Nyanza District , Luanda, at 1140m, with no host data, 10.iii.2007 (S. Okajima), in NMK.

Paratypes, 8 females taken with holotype, in LETUA and NMK .

Comments. The head of each of the available specimens is tilted down, thus emphasising the length of the mouth cone such that this reaches just beyond the fore coxae. The species is closely related to hargreavesi , but has much shorter setae on the head and pronotum, and antennal segments III and IV have slightly less prolonged apices ( Figs 12 , 23 ).
