Figs 3 A–F
Male. Colour. Head 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 entirely yellowish, sometimes apical fourth of hind femur infuscated. Wing with slightly brownish tinge; haltere yellow with light brown knob. Abdomen light brown, medial 2/3 of tergites dark brown. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Fourth antennal flagellomere 1.6 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with 3–4 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.2 times longer than palpomere 4. Nine strong postocular setae. Thorax. Anepisternum with 22–26 setae; anterior basalare and preepisternum 2 nonsetose; laterotergite with 9–12 setae; metepisternum with 8–9 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 1.3–1.4 mm. Hypopygium. Figs 3 A–F: Sternite 9 with the lateral margin roundly convergent posteriorly, posterior margin shallowly concave, extending beyond the middle of distance from the anterior margin of gonocoxa to base of the gonostylus, anterior margin medially deeply incised, few setae present, similar to the adjacent ventral setae of gonocoxa. Ventral medial margin of gonocoxa angularly produced medially, posterolateral part forming a short lobe, the ventral setae of gonocoxa unmodified, those on the posterolateral lobe stronger. Parastylar lobe finger-like, in ventral view covered by the gonocoxa, with 1 seta. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa indistinct on posterior part, with a row-like aggregation of short setae on posterior part, medial margin partly confluent with a more medial and more ventral plate-like lobe bearing several setae on ventral surface; two flame-shaped megasetae at the medial margin, dorsally from the juxtagonostylar megasetae. General setosity on the dorsal side of gonocoxa similar to the ventral one. Two juxtagonostylar setae present as flattened megasetae with a seta-like branch, both arising from a common basal body that is slightly shorter than the megasetae. Gonostylus transversely elongate oval, parallel with the ventral medial margin of gonocoxa, with a group of fine setae at the medial margin on the ventral side, with 3 megasetalike setae at posterior margin, directed dorsally, in addition with ca. 2 setae on the dorsal surface. Aedeagus narrow, parallel-sided, with wing-like membranous lateral lobes, the apex curved ventrad. Hypoproct extending posteriorly over the apex of gonostyli, the number of ventral setae (sternite 10) ca. 6 on each half. Cerci medially separate. Female. Unknown.
Discussion. Manota aligera belongs to a large group of Neotropical species that have a setose laterotergite and long posterolateral lobes on the gonocoxa. Within this group M. aligera shares a well-developed (i.e. with distinct and long lateral margins) sternite 9 with only a few species, viz. M. anfracta, M. bihamata, M. ciliata, M. digitata, M. incisa, M. micella, M. micula, M. penicillata and M. spinosa. However, M. aligera differs from all New World species by its unusual gonostylus that is shorter than broad (longer than broad in case of other species) and with a specific chaetotaxy (Fig. 3 A).
Etymology. The name is Latin, aligera, ‘winged’, referring to the wing-like lobes on the sides of the aedeagus.
