Manota ciliata sp. n.

Figs 6 A–D

Male. Colour. Head blackish 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 brownish tinge; haltere yellow with blackish 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 1.3–1.5 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 1.4 times longer than palpomere 4. Ten strong postocular setae. Thorax. Anepisternum with 28–41 setae; anterior basalare and preepisternum 2 non-setose; laterotergite with 18–24 setae; metepisternum with 6–9 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 1.4–1.5 mm. Hypopygium. Figs 6 A–D: Sternite 9 almost round, with a rather weak notch anteromedially, posterior margin extending to the middle between the base of gonocoxa and gonostylus, the setae similar to those on the ventral side of gonocoxa. Ventral medial margin of gonocoxa simple, with a notch at the base of gonostylus, posteriorly forming a broad lobe together with the lateral margin. The ventral setosity of gonocoxa unmodified, the setae rather weak. Parastylar lobe elongate, directed posteriad, apically narrowed, with two setae. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, convex, with a row of very large setae. Otherwise the dorsal setosity similar to the ventral one. Two juxtagonostylar setae present as unmodified megasetae, both arising from a common basal body that is slightly shorter than the setae. Dorsally from the juxtagonostylar setae two megasetae, each of which arising from its own low basal body. Inside the gonocoxa, best seen in dorsal aspect, a membrane with small trichia-bearing pimples. Gonostylus elongate oval, the apicomedial and apicolateral parts appearing as small lobes, a group of very small setae ventrally at the weak basomedial angle, a few long marginal setae posteromedially and 3 rather strong but short setae apicolaterally; the dorsal side non-setose. Aedeagus subtriangular, the lateral sides slightly concave, the apex curved ventrad. Hypoproct extending posteriorly to the apex of gonostyli, the number of ventral setae (sternite 10) ca. 12 on each half. Cerci medially separate.

Female. Unknown.

Discussion. Manota ciliata belongs to a large group of Neotropical species with a setose laterotergite and long posterolateral lobes on the gonocoxa. Within this group, M. ciliata shares a well-developed (i.e. with distinct and long lateral margins) sternite 9 with the following species: M. aligera , M. anfracta , M. bihamata , M. digitata , M. incisa , M. micella , M. micula , M. penicillata and M. spinosa . However, M. ciliata is clearly distinguished by the row of long and strong setae on dorsal medial margin of the gonocoxa. This character alone is enough to distinguish the species from any other known Neotropical Manota species.

Etymology. The name is Latin, ciliata , ‘ciliate’, referring to the row of long setae on the dorsal medial margin of the gonocoxa.
