Manota nubicola sp. n.

Figs 1 A, B, C, 5 A–D

Male. Colour. Head pale brown, frons, vertex and dorsal part of occiput darker brown, pedicellus and ventral part of flagellomeres 1–3 paler than rest of antenna, mouthparts paler than face. Thorax brown, preepisternum 2 paler than the other parts. Legs unicolorous pale yellowish. Wing unicolorous yellowish-brown; haltere yellowish-brown with dark brown knob. Abdominal tergites brown, sternites very pale, almost colourless. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 5 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 3 apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 1.1 times as long as palpomere 4. Number of large postocular setae 10–11. Thorax. Anepisternum setose, with 45–70 setae, anterior basalare non-setose, preepisternum 2 non-setose, laterotergite setose, with 16–29 setae, episternum 3 setose, with 1–3 setae. Wing, Figs 1 A, B, length 2.0 mm; right wing with an unusual Cu in one paratype ( Fig. 1 A). Hypopygium, Figs 5 B, C, D: Sternite 9 with the lateral margin fused with gonocoxa, posterior margin transverse, concave, not quite reaching middle length of gonocoxa, anterior margin deeply incised, setae few, similar to the adjacent ventral setae of gonocoxa. Ventral mesial margins of gonocoxa convex, rather close to one another. Mesial margins continuing after a sharp postero-mesial angle as a concave posterior margin which is connected to a rather small lateral lobe. Ventral setosity of gonocoxa unmodified, at posterior margin with a curved seta differing from other setosity, posterolaterally with two very strong setae and a row of circa 5 shorter setae. No parastylar lobe observable. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa convex, the details appearing very different in different mounts. At dorsal medial margin, lying on a more ventral level, with an elongated lobe bearing three small setae on its posterior end and one slightly stronger seta on its anterior end. Setae on dorsal side of gonocoxa unmodified. Two juxtagonostylar megasetae present, the more ventral one rather weak and simple, the more dorsal one similar but with a large subbasal leaf-like lobe, both setae arising from a common basal body which is almost as long as the setae. Gonostylus broadly oval in lateral or mesial view, narrow in ventral or dorsal view, on ventral side with a few setae at margin and 2–3 longer setae at apex, lateral side non-setose, at dorsomesial margin with a few setae, mesial side with a few scattered setae. Aedeagus elongate-subtriangular, without distinct lateral shoulders, without submembraneous lateral lobes on posterior half, the apex curved ventrad. Hypoproct large, posteriorly extending just over the base of gonostyli, with circa 30 scattered setae on each half. Cerci mesially separate. Tergite 9 unusually well visible and connected with the cerci.

Female. Unknown.

Discussion. M. nubicola resembles M. acutistylus Jaschhof & Hippa , M. rotundistylus Jaschhof & Hippa , M. planistylus Jaschhof & Hippa , M. rectolobata Jaschhof & Hippa and M. intermedia Jaschhof & Hippa , all known from Costa Rica, as well as M. mexicapan . M. nubicola differs from M. acutistylus and M. rotundistylus by having the posterolateral lobe or apophysis of gonocoxa short, not more than one-third of the length of the gonostylus, while in the two other species it is longer than the gonostylus; and from M. planistylus , M. rectolobata , M. intermedia and M. mexicapan by having the 1+3 setae on the lobe at the dorsomesial margin of the gonocoxa fine, not thick megasetae, and by having a finger-like hyaline lobe at the latter.

Etymology. The name is derived from the Latin, nubes, cloud, - cola, -dweller, referring to the collecting habitat in a cloud forest.
