Hippa, Heikki, Kurina, Olavi & Sääksjärvi, Ilari E., 2017, The genus Manota Williston (Diptera: Mycetophilidae) in Peruvian Amazonia, with description of sixteen new species and notes on local species richness, Zootaxa 4236 (1), pp. 1-40 : 9-11

Manota calva sp. n.

Figs 5 A–C

Male. Colour. Head dark brown, face somewhat paler to yellow. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax yellow to light brown, medial part of scutum and scutellum somewhat darker. Legs entirely yellowish. Wing with slightly 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 1.5 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with two apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.1–1.2 times longer than palpomere 4. Ten strong postocular setae. Thorax. Anepisternum with 27–48 setae; anterior basalare, preepisternum 2 and laterotergite non-setose; metepisternum with 6–9 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 1.1–1.2 mm. Hypopygium. Figs 5 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 broadly v-shaped incised medially, nonsetose. Ventral medial margin of gonocoxa forming a right-angled lobe between the posterior margin of sternite 9 and gonostylus, forming a posterolateral lobe with the lateral margin. The ventral setae of gonocoxa unmodified, rather long. Parastylar lobe probably only represented by 1 seta at the ventral medial margin of gonocoxa. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa convex. The dorsal setosity of gonocoxa similar to the ventral one. Posteriorly at the dorsal medial margin, on more ventral level a subtriangular plate-like lobe with long setae at medial margin. Two juxtagonostylar setae present as unmodified strong and long setae, both arising from a common basal body that is nearly as long as the setae. Gonostylus elongate oval, ventrally and apically with a few long setae, dorsally non-setose, medially on the apical half with 6 curved short megasetae. Aedeagus subtriangular, the apex curved ventrally. Hypoproct extending posteriorly to near the apex of gonostyli, the number of ventral setae (sternite 10) ca. 8 on each half. Cerci medially separate.

Female. Unknown.

Discussion. For discussion, see under Manota nuda .

Etymology. The name is Latin, calva , ‘bald’, referring to the non-setose sternite 9.
