Craspedothrips reticulatus sp.n.

( Figs 26–29 )

Female macroptera. Body brown, also mid and hind femora; mid and hind tibiae yellow, also fore legs; fore wing including clavus light brown; antennal segments I–II and IV–VIII brown, III yellow; major setae light brown.

Head wider than long, cheeks straight; ocellar setae pair I short, arising close together, II longer and lateral to first ocellus, III long 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, with stout 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, 3 pairs of postero-marginal setae. Mesonotum transversely reticulate, anterior campaniform sensilla present, median setal pair close to posterior margin. Metanotum with strong equiangular reticulation; median setae stout, close to lateral pair; campaniform sensilla present. Prosternal ferna slightly separated medially; mesothoracic sternopleural sutures complete; metapre-episternum band-like bearing one seta.

Abdominal tergite I without craspedum, with prominent equiangular reticulation, each reticle with curved anterior margin, tergite II with row of 5 similar reticles at anterior; tergites II–VIII with narrow band-like craspedum; V–VIII with no sculpture between median pair of setae, laterally with 5 or 6 weak transverse lines; VIII with lateral ctenidium-like structure weakly developed; IX with two pairs of campaniform sensilla, median dorsal setae long and extending to posterior margin; X short with no split.

Sternite II with 3 pairs of minute setae near anterior margin; II–VI with narrow craspedum lobed between marginal setal bases, VII with no craspedum; II with 2 pairs of marginal setae, III–VII with 3 pairs, on VII S1 and S2 arise far in front of margin.

Measurements (holotype female in microns). Body length 1500. Head, length 75; width 150; ocellar setae pair III 50. Pronotum, length 125; width 175; posteroangular setae—inner 75, outer 60; separation between pronotal striae medially 3–5. Fore wing length 800. Antennal segments III–VIII length, 55, 75, 48, 65, 10, 20.

Male: Similar to female but smaller and paler; pronotum less prominently sculptured; metanotal reticles less uniform, almost concentric on posterior half; tergite I similar to that of female, sculpture on II prominent but more irregular; tergites without craspeda, III–VIII with almost no sculpture; IX with no anterior campaniform sensilla, median dorsal setae short and stout; sternites without pore plates. Antennae with only 7 segments; segment III short and broad, IV–VI elongate with many very long setae ( Fig. 29 ).

Specimens studied. Holotype female, KENYA, Western District, Kakamega Forest , at 1620m, no host data, 4.iii.2007 (S. Okajima), in NMK . Paratype, 1 male collected with holotype, in NMK .

Comments. The two specimens on which this species is based bear the same collection data as two females of poecilus , but in contrast to that species there are craspeda on the tergites in the female. Moreover, the sculpture on the first abdominal tergite is unlike that of any other species of Thripinae .
