Manota uncinata sp. n.

( Figs 8 A, B, C)

Male. Colour. Face yellowish-brown, frons, vertex and occiput dark brown, antennal scapus and pedicellus concolorous with face, flagellum slightly darker brown, mouthpart pale yellowish. Thorax pale brown, prothorax and ventral part of preepisternum 2 paler yellowish-brown, this character is not very well seen in the single specimen. Legs pale yellowish, about basal third of femur 3 indistinctly infuscated. Wing unicolorous pale brown; haltere pale brown with brown knob. Setae brown, the thinner ones seeming pale, the thicker ones darker. Head. Antennal flagellomere 4, Fig. 8 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 apically expanded curved sensilla, palpomere 4 with parasegment. Number of postocular setae 9. Thorax. Anepisternum setose, with 39 setae; anterior basalare setose, with 8 setae; preepisternum 2 non-setose; laterotergite setose, with 23 setae; episternum 3 setose, with 7 setae. Wing. Length 1.8 mm. Hypopygium, Figs 8 B, C: Sternite 9 laterally fused with gonocoxa, extending posteriorly to base of gonostylus, posterior margin nearly straight, anterior margin with a narrow deep cleft, the setae similar to ventral setae of gonocoxa. Parastylar lobe directed obliquely posteriad, long and rather broad, with one apical seta. Paraapodemal lobe not observable. Dorsal mesial margin of gonocoxa with an angular bulge mesiad near middle, the more apical part of margin continuing to apicolateral lobe of gonocoxa. Between the bulging part of the dorsal mesial margin and apicolateral lobe, on a more ventral level, with a lobe bearing two megasetae pointing anteromesiad. Apicolateral lobe curved and non-setose except for a few apical setae and extending posteriorly to middle of gonostylus. One juxtagonostylar seta present: it is a knife-blade-like megaseta arising from a basal body which is about two-thirds of its length. Gonostylus elongate subquadrangular, the setae moderately long, mostly on the marginal areas, on one side in the single specimen with an outstanding stronger and longer seta at apical margin. Tegmen with a narrow apical half, and basal half widening towards base, without distinct lateral shoulders, the apodeme unusually expanded. Hypoproct large, posteriorly extending as far as apex of gonostylus, with ca. 30 setae on each half, the setae in distinct, more anterior and more posterior groups, the former in Fig. 8 C covered by sternite 9. Cerci medially separate.

Female unknown.

Discussion. M. uncinata is similar to M. clinochaeta and M. phyllochaeta but is distinguished from both e.g. as follows: 1) the parastylar lobe is twice as broad, 2) the megasetae at the dorsal mesial margin of the gonocoxa are twice as long and are directed obliquely anteriad, not posteriad, 3) the apodemes of the tegmen are unusually expanded and 4) the gonostylus is simple, without a trace of being bilobed, and its apex is as broad as the base, i.e. it is not attenuated towards the apex (or the apex of the dorsal lobe). M. uncinata is also similar to M. teocchi from which it differs by the characters mentioned under 2) and 4). Characters 1) and 3) are not known in M. teocchi .
