Manota hexacantha sp. n.

Figs 7 A–E

Male. Colour. The single specimen seems strongly faded. Head pale brown, vertex darker brown. Antenna unicolorous pale brown. Mouthparts pale yellowish. Thorax unicolorous pale brown. Legs unicolorous pale yellowish. Wing unicolorous yellowish; haltere yellowish-brown with darker knob. Abdominal tergites pale brownish, sternites paler but not clearly visible. All setosity yellowish or brownish, thicker setae apparently darker than finer setae and trichia. Head. Antennal flagellomere 4, Fig. 7 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 broken off on both sides. Eleven strong postocular setae. Thorax. Anepisternum setose, with 31 setae; anterior basalare non-setose; preepisternum 2 setose, with ca. 19 setae; laterotergite non-setose; episternum 3 setose, with 8 setae. Wing. Similar to Fig. 1 A; wing length 1.5 mm. Hypopygium, Figs 7 B–E. Sternite 9 rather long, posteriorly extending to level of parastylar lobes, with sharply delimited convex lateral margin, posterior margin with deep indentation, anterior margin deeply incised, setae similar to adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, sigmoid. Parastylar lobe oval in outline, with three setae anteriorly. Paraapodemal lobe present, but not clearly visible in the single mount and not drawn in Figs 7 B and C. The dorsal mesial margin of gonocoxa simple, slightly sigmoid, with a small setose lobe subapically and a prominent strong seta arising from a long basal body apically. Two juxtagonostylar setae present, both long apically curved megasetae arising from a common basal body, as long as megasetae. Gonostylus elongate falcate in outline, simple, dorsal side concave, ventral side with moderately long setosity, dorsal side with similar setosity on apical half. Aedeagus rather short subtriangular with weak lateral shoulders, apex curved ventrad. Hypoproct posteriorly extending to level of base of gonostylus, ventrally with a mesial row of 5–6 setae (sternite 10) on each half. Cerci mesially separate.

Female unknown.

Discussion. M. hexacantha resembles M. pellii Hippa ( Thailand) . It differs e.g. by having the juxtagonostylar megasetae almost parallel and as long as their basal body, not divergent and not much shorter than their basal body, by the outline of the gonostylus being falcate, not obovate and by lacking a row of short strong setae dorsally at the apical margin of the gonostylus.

Etymology. The name is derived from the Greek words hex, six and akantha, thorn, and refers to the six long, strong setae dorsally at the apical parts of the gonocoxae.

Types. Holotype. Male, Malaysia, Sabah, Danum Valley, 8.vii.–12.viii.1986 (in NHM).
