Manota serrulata sp. n.

Figs 19 A–D

Male. Colour. Head light brown, face somewhat paler. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax light brown, medial part of scutum and scutellum somewhat darker. Legs yellowish, apical fourth of hind femur infuscated. Wing with slight brownish tinge; haltere yellow with brown knob. Abdomen light brown, medial 2/3 of tergites darker. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Fourth antennal flagellomere 1.5 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with three apically curved and flattened sensilla; palpomere 4 with parasegment; palpomere 5 about 1.1 times longer than palpomere 4. Nine strong postocular setae. Thorax. Anepisternum with 30–42 setae; anterior basalare and preepisternum 2 non-setose; laterotergite with 12–19 setae; metepisternum with 6–7 setae along its margin. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 1.5–1.6 mm. Hypopygium. Figs 19 A–D: Sternite 9 laterally fused with gonocoxa except for the posteriormost part, the posterior margin concave, not extending beyond the middle of the distance between anterior margin of the gonocoxa and base of the gonostylus, anterior margin with a deep narrow incision medially, the setae similar to the adjacent setae of gonocoxa. Ventral medial margin of gonocoxa long because gonocoxa is drawn into a long posterolateral prong that bears four prominent lobes, an acute non-setose lobe at the gonostylus, a broad lobe bearing a megaseta and several short setae just posteriorly from the gonostylus, posteriorly from this a mall subtriangular lobe bearing a short megaseta and posteriorly from the latter a subtriangular serrated lobe; the long lateral prong with a group of short apical megasetae. The ventral setae of gonocoxa unmodified, rather short. Parastylar lobe roundly subtriangular, with two setae on medial margin. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, slightly convex. The dorsal setae of gonocoxa similar to those on the ventral side. Two rather short juxtagonostylar setae present, both are broad megasetae arising from separate low basal bodies. Gonostylus subquadrangular, with a long seta at basomedial angle, with a strong dorsally curved megaseta at apicomedial angle and with two weaker dorsally curved megasetae in a more lateral position at the apical margin. Aedeagus subtriangular, with lateral shoulders, the apex curved ventrad. Hypoproct extending posteriorly much over the apices of gonostyli, the number of ventral setae (sternite 10) ca. 10 on each half. Cerci rather small, medially separate.

Female. Unknown.

Discussion. By combination of the setose laterotergite, the gonocoxa fused laterally with sternite 9 leaving only the posterior margin distinct, and unusually long posterolateral lobes of the gonocoxa, M. serrulata differs from any other New World Manota species. Manota serrulata resembles somewhat M. spinosa in having the posterolateral lobes of the gonocoxa with short and acute megasetae apically, and the gonostyli attached to the gonocoxa at the middle of its length. Otherwise the two species are very different, distinguished for instance by lobes at the ventromedial margin of the gonocoxa, the shape of the parastylar lobes and juxtagonostylar setae, the rather long lateral margin of sternite 9 in M. spinosa and other details of the hypopygium.

Etymology. The name is Latin, serrulata , ‘with a little saw’, referring to the toothed lobe ventromedially on the posterior part of gonocoxa.
