Manota clivicola sp. n.

Figs 5 A–D

Male. Colour. Head brown, face somewhat paler. Antenna with scape and pedicel brown, flagellum absent in holotype. Clypeus and mouthparts pale yellowish. Thorax light brown, medial part of scutum and scutellum darker. Legs yellowish, hind coxa basally and hind femur basally and apically slightly infuscated. Wing hyaline with apical half slightly infuscated; haltere yellow with brownish knob. Abdomen light brown, medial 2/3 of tergites darker. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with four apically flattened and curved sensilla; palpal segment 4 with parasegment; palpal segment 5 missing in holotype. Nine strong postocular setae. Thorax. Anepisternum with 44 setae; anterior basalare non-setose; preepisternum with 12 setae; laterotergite with 17 setae; metepisternum with 8 setae. Legs. Hind tibial organ absent; midtibiae missing in holotype. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 proximally not extending to the level of the tip of R1; wing length 1.9 mm. Hypopygium, Figs. 5 A–D. Sternite 9 elongate subquadrangular, almost as long as the ventral part of gonocoxa, lateral margin separated from gonocoxa, anterior margin deeply incised, posterior margin transverse, the setae similar to the ventral setae of gonocoxa. Ventromedial margin of gonocoxa simple, concave. The ventral setae of gonocoxa normal, unmodified. Parastylar lobe oblique, sickle-shaped, with broad posterior and narrow anterior part, with a finger-like transverse lobe, the latter with two apical setae, a third seta at the base of the lobe on dorsal side (in Fig. 5 B the lobe is broken off from the right side and is shown in Fig. 5 C). Paraapodemal lobe similar to Fig. 2 B. Dorsomedial margin of gonocoxa convex, with short setae on posterior half. At the posterior margin of the gonocoxa there is a large oblique lobe bearing subapically on the ventral side a small sub-lobe. The first one has ~10 setae at the apex and along its medial margin, the second one has three apical setae. The dorsal setosity of gonocoxa normal, similar to the ventral one except one stronger setae posteriorly. Gonostylus nearly as long as the ventral length of gonocoxa, anteroposteriorly elongated with convex lateral and concave medial surface, submedially with a long slightly sigmoid megaseta, the setosity generally unmodified, confined on lateral/ventral parts, a few somewhat stronger setae at the ventromedial margin; the microtrichia on the medial surface long and conspicuous. Two juxtagonostylar setae present, one is an unmodified seta, the other is a sigmoid megaseta, both arising from a common basal body that is about one half of the length of the megaseta. Aedeagus elongate subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct extending posteriorly to the base of gonostylus, the ventral part (sternite 10) with ~10 scattered setae. Cerci short, medially fused except for a U-shaped notch apically, with apical setae only.

Female unknown.

Discussion. Manota clivicola belongs to a large group of species as defined under M. acris . Within this group M. clivicola resembles the species with one long megaseta on the apical half of gonostylus, viz. M. acris , M. apentachaeta , M. feminea , M. orthacantha , M. pacifica , M. parilis and M. pentachaeta . However M. clivicola differs from all of these in having the gonostylar megaseta almost submedian, not subapical or apical. In M. clivicola the posterodorsal lobe on the gonocoxa is apically divided into two parts. In this respect it resembles M. pacifica and M. sicula , but the detailed structure of these lobes is different. The unusually elongate gonostylus resembles that of M. unisetata . Unlike other mentioned species, M. clivicola has an apically infuscated wing.

Etymology. The name is Latin, clivicola [hill inhabitant] referring to the high altitude of the type locality.

Types. Holotype. Male, PAPUA NEW GUINEA, NE, Morobe district, Mt. Missim, 1900 m, 10–15.v.1967, G. A. Samuelson Collector (BPBM).
