Manota bruneiensis sp. n.

Figs 1 A, 4 A, B, C

Male. Colour. All specimens seem rather faded. Head pale brown, frons and vertex darker brown. Antenna unicolorous pale brown. Mouthparts pale yellowish-brown. Thorax unicolorous pale brown, postero-dorsal part seems a little darker. Legs unicolorous pale yellowish. Wing unicolorous yellowish; haltere yellowishbrown with darker knob. Abdominal tergites brownish, sternites paler yellowish-brown. All setosity pale, yellowish or brownish, thicker setae seeming darker than finer setae and trichia. Head. Antennal flagellomere 4, Fig. 4 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 1.2–1.4 times as long as palpomere 4. Nine to ten strong postocular setae. Thorax. Anepisternum setose, with 43–67 setae, anterior basalare non-setose, preepisternum 2 setose, with ca. 20–30 setae, laterotergite non-setose, episternum 3 setose, with ca. 5–13 setae. Wing. Fig. 1 A; wing length 1.8–2.0 mm. Hypopygium, Figs 4 B, C. Sternite 9 about two thirds of ventral length of gonocoxa, narrow, parallel-sided, completely free from gonocoxae, posterior margin with deep v-shaped indentation, anterior margin deeply incised, setae similar to adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, roundly curved. Parastylar lobe transverse, with 2 setae at mesial margin. Paraapodemal lobe well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, with a small rounded setose lobe posteriorly at base of long oblique apical lobe, with a patch of non-modified setae at apex. Two juxtagonostylar setae, both long apically curved or sigmoid megasetae arising from a common basal body, as long as megasetae. Gonostylus complex, with a parallel-sided basal part, flattened oblique apical part and an angulate dorsal lobe, with an oblique, inflated apex; ventral side with short unmodified setae except for flat non-setose apical lobe, dorsal side non-setose except for a row of long setae on dorsal lobe and a row of short setae at apex of apical lobe. Aedeagus rather small, subtriangular with weak lateral shoulders, the apex curved ventrad. Hypoproct unusually small, posteriorly extending to the level of base of gonostylus, ventrally with ca. 10 scattered setae on each half. Cerci mesially separate.

Female unknown.

Discussion. M. bruneiensis superficially resembles a number of other Manota species, but differs in detail. They all share the setose anepisternum and preepisternum 2, nonsetose anterior basalare and laterotergite, short vein R1, laterally free tergite 9, a long apical lobe dorsally on the gonocoxa and two subequal juxtagonostylar megasetae arising from a long common basal body. M. bruneiensis is easily distinguished by its quite unique gonostylus with a flat oblique apical lobe and an angled dorsal lobe.

Etymology. The name is derived from the State of Brunei, where the type locality is situated, by adding the Latin suffix - ensis, denoting place.

Types. Holotype. Male, BRUNEI, Ulu Temburong, 14.ii.–9.iii.1982, Malaise trap, M. C. Day leg. (in NHM).

Paratypes. 3 males with the same data as holotype (in NHM).
