Manota integra sp. n.

Figs. 3 A–E

Male. Colour. Head pale brown, frons and vertex slightly darker brown. Antenna pale brown, scape, pedicel and flagellomeres 1–2 slightly paler ventrally than other parts. Mouthparts pale yellowish. Thorax dorsally brown, laterally paler brown, preepisternum 2 much paler ventrally than other parts of pleura. Legs pale yellowish brown, apices of mid- and hind coxae darker, mid- and hind trochanters and the extreme base of hind femur infuscated. Wing pale yellowish-brown, diffusely darker brown at anterior margin; halter brown. Abdomen brown. All setosity yellowish or brownish, thicker setae apparently darker than finer setae and trichia. Head. Antennal flagellomere 4, Fig. 3 A . Palpomere 3 of maxillary palpus without apicomedial thumb-like extension, without apically expanded curved sensilla; palpomere 4 with indistinct parasegment which appears more like an apicomedial angle, palpomere 5 ca. 1.3 times longer than palpomere 4. Number of strong postocular setae 16. Thorax. Anepisternum, anterior basalare, and preepisternum 2 non-setose; laterotergite setose, with 24 setae; episternum 3 non-setose.

Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C at the middle of the costal margin, the sclerotized part of M2 extending well on the basal half of wing; wing length 1.9 mm. Hypopygium, Figs. 3 B–E : Sternite 9 about half the ventral length of gonocoxa, with sharply delimited, posteriorly convergent, lateral margins, posterior margin rounded, anterior with deep V-shaped indentation, setae similar to adjacent setae of gonocoxa. Medial margin of gonocoxa appearing as a large subtriangular lobe. No distinct parastylar lobe visible, but there are a small, curved, apically setose lobe and a membranous non-setose lobe posteriorly at ventromedial margin of gonocoxa (see Fig. 4 B ), either one or both of which may be the parastylar lobe. Dorsomedial margin of gonocoxa simple, slightly convex. No lateral lobe dorsally at posterior margin of gonocoxa. A transverse plate-like lobe present at the ventromedial margin of gonocoxa, with 6–7 megasetae posteriorly. Dorsal gonocoxal setae similar to the ventral ones. Two juxtagonostylar setae present, both strongly modified megasetae, the ventral one flameshaped, the dorsal one multi-lobed, both arising from a common large plate-like basal body. Gonostylus ca. 3 times longer than broad, elongate oval with medial sub-basal thumb-like lobe, ventral side evenly covered by rather short setae, dorsal side non-setose except for a stripe of setae in middle. Aedeagus subtriangular, without distinct lateral shoulders, apex curved ventrally. Hypoproct posteriorly pointed, posterior margin at level of basal part of gonostylus, ventrally (sternite 10) with ca. 15 setae. Tergite 9 unusually well developed, with distinct anterior, lateral and posterior margin, and 6 setae. Cercus long, with subtriangular medial and rounded sub-basal lateral lobe; cerci fused at extreme base.

Female unknown.

Discussion. Manota integra is grouped with M. avita Hippa and M. sinepollex Hippa & Ševčík based on the nonsetose anepisternum and preepisternum 2, wing vein R1 joining vein C at the middle of the costal margin of wing, the setose laterotergite, the well-developed setose tergite 9 and the unusually long cercus with unusual lobes. It is distinguished from both in having a narrow thumb-like lobe sub-basally on the medial margin of the gonostylus. In M. avita there is also a lobe on the gonostylus but it is placed sub-basally on the lateral margin and curves medially over the dorsal surface of the gonostylus.

Etymology. The name is Latin, integra , complete, restored, referring to the well-developed tergite 9 unlike in most other Manota .

Types. Holotype. Male, China, Yunnan, Luchun-x , 11.5 km SW of Yanjia, 1750–1800 m, 30 May 1996, T. Saigusa col. (in KIZ).
