Manota aristoseta View in CoL sp. n.
Figs 4 View FIGURE 4 A–C
Male. Colour. Head brown, face somewhat paler. Antenna including scape and pedicel light brown. Clypeus and mouthparts yellowish. Thorax yellow, medial part of scutum and scutellum somewhat darker. Legs entirely yellowish. Wing with slight brownish tinge; haltere yellow with 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 1.8 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with three apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.2–1.3 times longer than palpomere 4. Nine strong postocular setae. Thorax. Anepisternum with 39–51 setae; anterior basalare, preepisternum 2 and laterotergite non-setose; metepisternum with 9–11 setae. 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 4 View FIGURE 4 A–C: Sternite 9 laterally fused with gonocoxa, the posterior margin convex, not extending to the middle between the base of gonocoxa and gonostylus, anterior margin with a deep incision medially, the setae few, similar to the adjacent ventral setae of gonocoxa. Ventral medial margin of gonocoxa convex, the ventral setae of gonocoxa unmodified; posterolateral part not drawn into a lobe. Parastylar lobe membranous, covered by the medial part of gonocoxa, with one seta. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa convex, on posterior part with a row of 4 strong setae of which the posteriormost 2 are flat and dilated, especially on apical part, both with an arista-like branch. Otherwise the dorsal setosity similar to the ventral one, a few long setae posterolaterally. Ventrally from the dorsal medial margin two lobes, one plate-like and bearing a long megaseta, the other, more posterior, narrower and bearing a group of ca. 6 setae on its curved posterior part. Two juxtagonostylar setae present, the ventral one is an unmodified megaseta, the dorsal one is flattened and dilated, both megasetae arising from a common basal body that is slightly shorter than the megasetae. Gonostylus elongated subquadrangular, with a few setae at apicomedial angle, with a stronger seta arising from a finger-like lobe at apicolateral angle, otherwise gonostylus non-setose. Aedeagus subtriangular, the apex curved ventrad. Hypoproct extending posteriorly to the apex of gonostyli, the number of ventral setae (sternite 10) ca. 15 on each half. Cerci medially separate.
Female. Unknown.
Discussion. Manota aristoseta is very similar to M. pisinna and M. exigua and can easily be mistaken for them. It is distinguished from both in having the two megasetae on the posteromedial margin of the gonocoxa characteristically modified: apically dilated with the rounded apex supplemented by a seta-like branch attached to the base of the dilated part. In the two other species, the megasetae are dilated subapically leaving the apex narrow and seta-like. In M. aristoseta , the seta-like branch is probably homologous with the apex of the megasetae in the two other species. Further, M. aristoseta differs from the two other species in having a longer gonostylus and lacking numerous setae on its medial margin. For further discussion, see under M. exigua .
Etymology. The name is Latin, composed of the words arista, ‘awn or arista’, and seta, ‘bristle’, referring to the two setae at the dorsal medial margin of the gonocoxa that are apically flattened and expanded, and have an arista-like branch.
