Craspedothrips malaysiae sp.n.

( Figs 13–19 )

Female macroptera. Body brown, major setae dark brown; tibiae and tarsi yellow, femora light brown; fore wing including clavus deeply shaded; antennal segment III light brown with base and apex paler, IV brown with dark basal ring separated from most of this segment by narrow pale band.

Head wider than long, cheeks convex; ocellar setae pair I arise 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, posterior part of vertex with 4 or 5 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 very stout forked sensoria, apex of IV greatly elongate; lateral sensoria on V flattened; VI with 3 sensoria; VIII longer than VII.

Pronotum with many transverse lines and many discal setae, posterior submarginal area demarcated; 2 pairs of posteroangular setae, posterior margin with 3 (or 2) pairs of setae. Mesonotum transversely striate, anterior campaniform sensilla present, median setal pair close to posterior margin. Metanotum transversly striate on anterior half, reticulate on posterior; median setae stout, close to weaker lateral pair; campaniform sensilla present. Prosternal ferna slightly separated medially; mesothoracic sternopleural sutures complete; metapre-episternum band-like bearing one seta.

Abdominal tergite I transversely sculptured, without craspedum; II–VII with about 10 transverse line laterally, sculpture not extending mesad of discal setae S 2 in IV–VII; II–VIII with broad craspedum on posterior margin, lateral margins of craspedum on VIII form variable number of microtrichia; posteroangular setae on III–VI arise mesad of posterior angle of tergites; VIII with ctenidium-like row of microtrichia terminating at spiracle; IX with one pair of campaniform sensilla, median dorsal setae stout; X short with weak split.

Sternites II–VI with narrow craspedum lobed between major setae; II with 2 pairs of minute setae on anterior margin and a third pair sometimes almost medially, and 2 pairs of posteromarginal setae; III–VII with 3 pairs of marginal setae, on VII S1 and S2 arise well in front of margin.

Measurements (holotype female in microns). Body length 1350. Head, length (tilted) 80; width 150; ocellar setae pair III 12. Pronotum, length 135; width 185; posteroangular setae—inner 50, outer 40; separation between pronotal striae medially 3–5. Fore wing length 700. Antennal segments III–VIII length, 55, 75, 50, 55, 15, 23.

Specimens studied. Holotype female, SINGAPORE, from unidentified red flowers, 25.ix.2007 (D.J.Tree, 498), in ANIC.

Paratypes: 3 females collected with holotype. MALAYSIA, SABAH, from Medinilla amplectens flowers ( Melastomataceae ), vii–ix, 1999 (J.Kanstrup), in ANIC. INDONESIA, BALI, Tabanan, Muncak Sari, Pura Luhur, at 755m, 4 females without host data, 2.ix.2006 (S. Okajima), in LETUA.

Comments. Only one antenna remains on the holotype, and there are no antennae left on the paratypes from Singapore, images are therefore included here also of paratypes from Bali. The sensorium on antennal segment III of these paratypes is more slender than that of the holotype ( Figs 13, 14 ), moreover the pronotal posteroangular setae of these paratypes are longer than those on the holotype ( Figs 15, 16 ), with the setae on the paratype from Sabah intermediate in length. The antennae of malaysiae are similar to those of antennalis , but ocellar setae pair III are short, only about as long as the distance between the posterior ocelli, the pronotal posteroangular setae are also shorter, and the transverse striae on the pronotum are more closely spaced. In contrast to most other members of the genus, including antennalis , on sternite VII setal pair S2 of malaysiae arise at least three times the width of their basal pores anterior to the sternal margin ( Fig. 19 ).
