Manota stricta sp. n.

Figs 12 A, B, C

Male. Colour. The single specimen appears to be rather faded. Head pale brown, vertex and dorsal part of occiput darker brown. Antenna unicolorous pale brown. Mouthparts pale yellowish. Thorax pale brown, postero-medial part of scutum and almost all of scutellum darker brown. Legs unicolorous pale yellowish. Wing unicolorous pale greyish-brown; haltere yellowish-brown with darker brown knob. Abdominal tergites pale brownish, tergites 5 and 6 darker brown, sternites pale yellowish brown, sternite 6 darker brown, nearly as dark as tergite 6. All setosity yellowish or brownish, thicker setae appearing darker than finer setae and trichia. Head. Antennal flagellomere 4, Fig. 12 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 1.6 times as long as palpomere 4. Nine strong postocular setae. Thorax. Anepisternum setose, with 58 setae; anterior basalare non-setose; preepisternum 2 setose, with 17 setae; laterotergite non-setose; episternum 3 setose, with 17 setae. Wing. Similar to Fig 1 A; wing length 2.1 mm. Hypopygium, Figs 12 B, C. Sternite 9 about half ventral length of gonocoxa, with sharply delimited nearly straight lateral margin, posterior margin with deep indentation, anterior margin deeply incised, setae slightly shorter than adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, sigmoid. Parastylar lobe oblique, sickle-shaped, with 3 setae anteriorly (at apex). Paraapodemal lobe exposed in ventral view, its mesial angle with a submembranous projection. Dorsal mesial margin of gonocoxa simple, slightly convex. There is a rather small setose apicodorsal apophysis on the gonocoxa. Two juxtagonostylar setae present, both long, one thin, other thicker and megaseta-like, both arising from a common basal body which is about half length of setae. Gonostylus elongate sub-quadrangular with an apicomesial projection. Setae on ventral side moderately long, unevenly distributed with a non-setose area apicomesially, few setae on dorsal side, apicomesially with a patch of setae with one seta stronger, apicolaterally with few long and strong setae. Aedeagus unusually long, apex extending nearly as far as apex of gonostylus, lateral shoulders strong, relatively basal, the apical part narrow with small wing-like lateral lobes near the base, apex straight, not angularly curved ventrad. Hypoproct unusually narrow and elongated, posteriorly extending as far as apex of aedeagus, ventrally with a mesial row of ca. 6 setae (sternite 10) on each half. Cerci mesially separate.

Female unknown.

Discussion. M. stricta is similar to M. calcarata Hippa (Peninsular Malaysia), M. hyboloma sp. n. ( Malaysia: Sabah), M. procera Hippa (Peninsular Malaysia, Sarawak, Thailand) and M. transversa Hippa ( Malaysia) . It differs from all of these by its unusual aedeagus in which the apical part, posterior to the lateral shoulders, is narrow and elongated with unique wing-like lobes near the base. Even the hypoproct is unusually narrow. M. stricta and M. hyboloma have the apex of the aedeagus straight, not curved ventrad as in the other species. M. stricta and the other species mentioned above differ from M. hyboloma by lacking a projecting lobe posteriorly at the dorsal mesial margin of the gonocoxa. There is one other species of Manota , M. spadix Hippa (Peninsular Malaysia), which has a similar narrow and elongated posterior part on the aedeagus. In this species the aedeagal apex is laterally expanded, the parastylar lobe is lacking, the gonostylus is short obcordate and the laterotergite is setose.

Etymology. The name is derived from the Latin stricta , straight, referring to the straight apical part of the aedeagus.

Types. Holotype. Male, BRUNEI, 13.iv.1991, without other data (in NHM).
