Manota pilosa sp. n.

Figs 16 A–D

Male. Colour. Head pale brown, vertex and dorsal part of occiput dark brown. Antenna brown. Mouthparts pale yellowish. Thorax brown, posteromedial part of scutum and scutellum darker brown, ventral part of preepisternum 2 paler brown. Legs pale yellowish, apical fourth of femur 3 infuscated, in one paratype slight infuscation at base of F2 and F3. Wing pale brown; haltere pale brown with dark brown knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 16 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.5 times longer than palpomere 4. Number of strong postocular setae 9–11. Thorax. Anepisternum setose, with 34–46 setae; anterior basalare non-setose; preepisternum 2 setose, with 9–18 setae; laterotergite non-setose; episternum 3 setose, with ca. 11–22 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M extending to the level of the tip of R1, wing length 1.6–1.7 mm. Hypopygium, Figs 16 B–D: Sternite 9 half the length of gonocoxa, lateral margin sharply delimited, posterior margin rounded, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, rather straight. Parastylar lobe subtriangular, with unusually long microtrichia, with 6 setae, one anteroventrally, five in a row on the mesial surface. Paraapodemal lobe distinct, exposed in ventral view. Dorsal mesial margin of gonocoxa straight, with a lobe-like widening on a more ventral level. Gonocoxa posteriorly with two setose lobes: a shorter mesial one and a longer lateral, more dorsal one. Two juxtagonostylar setae present: a megaseta with flattened rounded apex and an unmodified seta, both arising from a common long basal body which is longer than the setae. Gonostylus as long as the ventral length of gonocoxa, unusually narrow, arcuate, the setae similar to those on the gonocoxa, few in number, lacking on a long basodorsal part. Aedeagus subtriangular, without lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae forming a mesial longitudinal stripe of ca. 8 setae on each half. Cerci medially separate, simple, the setae confined on the apex, short, the longest ones only slightly longer than subapical width of cercus.

Female unknown.

Discussion. Manota pilosa resembles M. whiteleyi . In addition to the characters outlined in the key it differs by having the basal two thirds of the gonostylus dorsally bare.

Etymology. The name is Latin, pilosa , hairy, referring to the densely microtrichose parastylar lobe.
