Figs 9 A, B, C
Male. Colour. The specimens appear to be rather faded. Head pale brown, frons, vertex and dorsal part of occiput darker brown. Antenna unicolorous pale brown. Mouthparts pale yellowish. Thorax pale brown, postero-medial part of scutum and scutellum apparently slightly darker brown. Legs unicolorous pale yellowish. Wing unicolorous pale greyish-brown; haltere yellowish-brown with darker brown knob. Abdominal tergites 1, 2, 7 and 8 pale brown, remainder darker brown, sternites pale yellowish brown, sternites 5 and 6 darker brown. All setosity yellowish or brownish, thicker setae apparently darker than finer setae and trichia. Head. Antennal flagellomere 4, Fig. 9 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 (holotype)–6 apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 1.3–1.5 (holotype) times as long as palpomere 4. Ten strong postocular setae. Thorax. Anepisternum setose, with 52 (holotype)–68 setae, anterior basalare non-setose, preepisternum 2 setose, with 16(holotype)–28 setae, laterotergite non-setose, episternum 3 setose, with 6(holotype)–20 setae. Wing. Similar to Fig 1 A; wing length 1.6 (holotype)– 1.9 mm. Hypopygium, Figs 9 B, C (paratype damaged). Sternite 9 about half the ventral length of gonocoxa, with sharply delimited slightly convergent lateral margins, posterior margin transverse, indistinct, membranous, anterior margin deeply incised, setae laterally shorter, medially longer and forming a weak tuft. Ventral mesial margin of gonocoxa simple, sigmoid. Parastylar lobe oblique, of sickleshaped form even if appearing a little different, especially on right side of mount of holotype (Fig. 9 C), with 4 setae anteriorly. Paraapodemal lobe exposed in ventral view, its mesial angle without a submembranous projection. Dorsal mesial margin of gonocoxa simple, slightly convex. Apex of gonocoxa dorsally with an apically setose apophysis. Two long juxtagonostylar setae, both rather unmodified megasetae arising from a common basal body, about half the length of setae. Gonostylus elongate, the basomesial corner produced as a prominent pointed lobe, apicomesially a small nose-like lobe with two extremely long setae, apico-dorsally with a small tuberculate lobe with short curved setae, otherwise setosity on ventral side rather short and sparse, on dorsal side largely absent. Aedeagus rather short, broadly subtriangular, with lateral shoulders, apical part curved ventrad, long. Hypoproct posteriorly extending to the level of basal part of gonostylus, ventrally with an irregular mesial row of ca. 10 long setae (sternite 10) on each half. In holotype a long seta arises from membrane between sclerotized basal margin of tergite 9 and cerci. Cerci mesially separate.
Female unknown.
Discussion. M. perangulata belongs to a common group of Manota in the Oriental region. They are characterised by having a well-developed apicomesial apophysis on the palpomere 3, a setose anepisternum and preepisternum 2, a non-setose anterior basalare and laterotergite, a short vein R1, the tergite 9 laterally free, the parastylar lobe obliquely sickle-shaped or subtriangular, an apically setose apophysis at the dorsal margin of the gonocoxa, two juxtagonostylar megasetae arising from a long common basal body and a hypoproct with a ventral mesial row of setae. M. perangulata is not very similar to the other species in this group and is easily distinguished by the prominent pointed basomesial corner of the gonostylus and the two extremely long apicomesial setae. M. dolichothrix has similar gonostylar setae but they are shorter than the gonostylus, four setae in total and they are not arising from a nose-like lobe.
Etymology. The name is derived from the Latin words per, very, and angulata, having a corner, referring to the sharp baso-mesial corner of the gonostylus.
