Manota setilobata sp. n. Figs 4 A–F, 6

Types.

Holotype. Male, COLOMBIA, Risaralda, SFF Otún Quimbaya Cuchilla Camino, 04°43'N, 75°35'W, 2050 m, Malaise trap, 08-24.v.2003, G. López Leg. M. 3673 (on slide, IAvH). Paratype. Male, same as holotype except 04-17.ii.2003, M. 3694 (on slide, IAvH).

Diagnosis.

Laterotergite non-setose; anterior basalare non-setose; sternite 9 posteriorly and anteriorly deeply incised, posterior third laterally free; parastylar lobe indistinct; posterolateral part of gonocoxa drawn into a narrow lobe; dorsomedial margin of gonocoxa with a large plate-like lobe bearing one strong seta at posteromedial corner; gonostylus elongated subquadrangular, slightly sunken into gonocoxa; two juxtagonostylar megasetae, both twisted, the more dorsal one apically flattened and dilated; posteriorly from the juxtagonostylar megasetae a narrow flat apically setose lobe.

Description.

Male. Colour. Head brown, face somewhat paler. Antenna light brown, including scape and pedicel. Clypeus and mouthparts yellowish. Thorax light brown. Legs yellowish. Wing with light brownish tinge because of microtrichia; haltere yellow with blackish knob. Abdomen with tergites dark brown to blackish, sternites light brown to yellowish. All vestiture pale, yellowish or brownish, thicker setae and trichia seeming darker than finer ones. Head. Antennal flagellomere 4 ca. 2.3 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with three apically curved sensilla; palpomere 4 with parasegment; palpomere 5 missing in both known specimens. Number of strong postocular setae, 10. Thorax. Anepisternum with 29-33 setae; anterior basalare, preepisternum 2 and laterotergite non-setose; metepisternum with 3-5 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C within basal half of costal margin; sclerotized part of M2 extending to level of tip of R1; wing length, 2.4 mm. Hypopygium (Fig. 4 A–F). Sternite 9 ca. 2/3 as long as gonocoxa, anterior 2/3 laterally fused to gonocoxa, posterior 1/3 free, posterior and anterior margins with deep incisions which separate the sclerite almost into two halves, covered with setae similar to adjacent ventral setae of gonocoxa. Ventral medial margin of gonocoxa simple. Parastylar lobe not identifiable with certainty, possible fused with gonocoxa and in Fig. 4A comprising the part visible between the posterior margin of sternite 9 and the gonostylus. No paraapodemal lobe observable. Posterolateral part of gonocoxa drawn into a narrow lobe. Dorsomedial margin of gonocoxa simple. In a more ventral level, a large plate-like lobe bearing one strong seta at posteromedial corner. Two juxtagonostylar megasetae present, both twisted, the more dorsal one apically flattened and dilated, both arising from basally fused basal bodies which are as long as the megasetae. Dorsally from juxtagonostylar megasetae, a flat apically setose lobe, connected with a thin, one seta bearing plate-like lobe anteriorly from it. Posteriorly from the juxtagonostylar megasetae a narrow flat apically setose lobe. Gonostylus elongated subquadrangular, slightly sunken into gonocoxa, with 4-5 strong and long setae at posterior margins, other setosity similar to that on gonocoxa ventrally, dorsal side non-setose. Aedeagus subtriangular, lateral sides slightly concave, apex curved ventrally. Hypoproct extending posteriorly over apex of gonostyli, each side with 4-5 strong setae apically and ca. 30 fine setae on ventral surface. Cerci medially separated.

Female. Unknown.

Discussion.

Manota setilobata sp. n. resembles M. multilobata sp. n. For a more detailed discussion on distinguishing characters, see above.

Etymology.

The specific epithet is Latin, setilobata [with seta-bearing lobes], referring to the apically setose lobes dorsally on the gonocoxa (adjective).
