Manota micella sp. n.

Figs 12 A–E

Male. Colour. Head brown, face yellowish. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax yellowish, medial part of scutum and scutellum somewhat darker. Legs yellowish, apical third of hind femur infuscated. Wing with slightly brownish tinge; haltere yellow with dark 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 1.1 times longer than palpomere 4. Nine strong postocular setae.

Thorax. Anepisternum with 19 setae; anterior basalare and preepisternum 2 non-setose; laterotergite with 15 setae; metepisternum with 7 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 1.4 mm. Hypopygium. Figs 12 A–E: Sternite 9 unusually large, lateral margin convex, posterior margin concave, extending over the middle between the base of gonocoxa and gonostylus, anterior margin deeply incised medially, the setae similar to the adjacent ventral setae of gonocoxa. Ventral medial margin of gonocoxa simple, convex, the ventral setae of gonocoxa unmodified. Parastylar lobe conical with two apical setae. No paraapodemal lobe identifiable but posterodorsally from the parastylar lobe a small lobe that could represent the paraapodemal lobe. Dorsal medial margin of gonocoxa simple, at the middle rather indistinct and confluent with a subtriagular lobe in more medial and ventral position. The posterior margin of this lobe with several setae on the ventral side. Just posteriorly from this lobe a short finger-like lobe bearing a long unmodified megaseta. The gonocoxa drawn into a long posterolateral lobe that has at the level of juxtagonostylar setae (partly covering them) a subquadrangular lobe with setose medial margin. Two juxtagonostylar setae present, the ventral one is a rather unmodified megaseta, the dorsal one is flattened and basally dilated, both megasetae arising from an apically divided basal bodythat is slightly shorter than the megasetae. Gonostylus elongate, simple, parallel sided, with four setae on the ventral side, one seta on the dorsal side, with a long strong seta subapically on the medial side plus two megasetae in a more basal position. Aedeagus subtriangular, with weak lateral shoulders, the apex curved ventrad. Hypoproct extending posteriorly to the apical part of gonostyli, the number of ventral setae (sternite 10) ca. 10 on each half. Cerci medially separate.

Female. Unknown.

Discussion. Manota micella belongs to a large group of Neotropical species that have a setose laterotergite and long posterolateral lobes on gonocoxa. Within this group M. micella shares a well-developed (i.e. with distinct and long lateral margins) sternite 9 that is at least as long as wide, with only a few species, viz. M. aligera , M. anfracta , M. bihamata , M. ciliata , M. digitata , M. incisa , M. micula , M. penicillata and M. spinosa . Manota micella is distinguished from all of them, as well as from any other Neotropical species by its elongate, narrow gonostylus with characteristic medial chaetotaxy: a long curved seta subapically plus two widely separated megasetae on the apical half.

Etymology. The name is Latin, micella , ‘small’, referring to the small size of the fly.

Types. Holotype. Male, PERU, Department of Loreto, Iquitos area , Allpahuayo , [1]– 15.x.2000, Malaise trap E3(14), I. E. Sääksjärvi et al. leg. (on slide, UNSM). Paratypes . 3 males, same data as holotype (on slides, UNSM, ZMUT, IZBE).
