Manota petiolata sp. n.

Figs 15 A–C

Male. Colour. Head pale brown, vertex and dorsal part of occiput dark brown. Antenna brown, scapus in some specimens slightly paler than the more distal parts. Mouthparts pale yellowish. Thorax brown, posteromedial part of scutum and scutellum darker brown, ventral part of preepisternum 2 paler brown. Legs pale yellowish, apical third of femur 3 infuscated, traces of slight infuscation at base of F2 and F 3 in some specimens. 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. 15 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. 1.3–1.4 times longer than palpomere 4. Number of strong postocular setae 8–9. Thorax. Anepisternum setose, with 38–58 setae; anterior basalare non-setose; preepisternum 2 setose, with 12–26 setae; laterotergite non-setose; episternum 3 setose, with ca. 11–29 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 1.6–1.9 mm. Hypopygium, Figs 15 B, C: 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, shallowly sigmoid. Parastylar lobe elongate subtriangular or slightly sickle-shaped with 2 setae on the anterior half, the setae arising from prominent basal bodies. Paraapodemal lobe distinct, exposed in ventral view. Dorsal mesial margin of gonocoxa simple, angularly convex. Dorsal posterior margin simple, posteromesial angle acute, apically rounded, with an aggregation of setae. On the ventral side of the latter there is a finger-like curved lobe bearing two apical setae Two juxtagonostylar setae present, both rather unmodified pointed megasetae arising from a common basal body which is almost as long as the megasetae. Gonostylus about half the length of gonocoxa, oval in outline, with a narrow mesial lobe on the apical half and which bears two megasetae at the apex; the ventral setae of gonostylus similar to those on gonocoxa, the lateral and apical setae conspicuously long, the dorsal side of gonostylus non-setose. Aedeagus elongate subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae strong and forming a mesial longitudinal stripe of ca. 6 setae on each half. Cerci medially separate, simple, the setae confined on the apical part, the longest ones several times longer than the subapical width of cercus, nearly as long as gonostylus.

Female unknown.

Discussion. Manota petiolata is greatly similar to M. comata , M. pedicellata and M. relicina and can easily be confused, particularly with M. relicina . It can be distinguished from M. relicina by the cercal setae which are long, the longest ones nearly as long as the cercus itself and as long as the gonostylus (in M. relicina the setae are scarcely longer than the width of cercus and less than a half of the length of gonostylus), and by the basal body of the juxtagonostylar megasetae which is shorter, about as long as the megasetae (in M. relicina about twice the length of the megasetae). For further discussion, see under M. relicina .

Etymology. The name is Latin, petiolata , having a small slender stalk, referring to the long basal body of the juxtagonostylar megasetae.
