Manota tayal sp. n.

Figs. 6 A–C

Male. Antennae and palpomeres beyond palpomere 2 broken off in the single specimen. Colour. Head brown, face paler brown. Mouthparts pale yellowish. Thorax brown, preepisternum 2 ventrally paler. Legs yellow, hind femur infuscated at base and on apical third. Wing unicolorous pale yellowish-brown; halter pale brown with darker brown knob. Abdomen brown. All setosity yellowish or brownish, thicker setae apparently darker than finer setae and trichia. Head. Number of strong postocular setae ca. 11. Thorax. Anepisternum setose, with 17 setae, anterior basalare setose, with 4 setae, preepisternum 2 setose, with 23 setae, laterotergite non-setose, episternum 3 setose, with ca. 13 setae. Legs. Midtibial organ absent. Hind tibial organ present. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 extending to the level of the tip of R1; wing length 1.8 mm. Hypopygium, Figs. 6 A–C . Sternite 9 about half the ventral length of gonocoxa, with sharply delimited convex lateral margins, posterior part attenuating to a narrow transverse posterior margin, anterior margin deeply incised, setae similar to adjacent setae on the gonocoxa. Ventromedial margin of gonocoxa simple, not well defined at the parastylar lobe. Parastylar lobe elongate oval, with 2 setae at the medial margin. Paraapodemal lobe distinct, in Fig. 6 A visible at the medial margin of parastylar lobe on the left side. Dorsomedial margin of gonocoxa simple, slightly convex. A subtriangular lobe posteriorly at the medial margin with ca. 15 strong setae at its posterior margin. Gonocoxa without posterolateral lobe. Dorsal gonocoxal setosity similar to the ventral. Two long juxtagonostylar setae present, one unmodified but strong seta, the other a flattened slightly angulate megaseta, both arising close to one another from a common low basal body. Gonostylus subrectangular, basomedial part\ produced medially, setae unmodified, similar to those of the gonocoxa, largely absent ventrally on the apical half, dorsally on the basal half, the sub-basal and subapical medial marginal setae forming an inconspicuous fringe. Aedeagus subtriangular, with weak lateral shoulders, the apex curved ventrally. Hypoproct extending posteriorly to the middle of gonostylus, with posterolateral angles, the ventral setae (sternite 10) scattered, not in rows, ca. 10 on each half. Tergite 9 membranous. Cerci medially separate, attenuating towards the apex, unmodified.

Female unknown.

Discussion. In the key to Oriental and Palaearctic Manota ( Hippa 2011) M. tayal runs to couplet 42 which leads to the oriental M. cristata Hippa and Palaearctic M. satoyamanis Hippa & Kjaerandsen on one hand and 12 other Oriental or Palaearctic species on the other. Like M. cristata and M. satoyamanis , M. tayal has a row of setae subbasally along the ventromedial margin of the gonostylus, even if these setae are not stronger than the other gonostylar setae, and there number is 6 instead of 5 and the setae do not give a distinct comb-like impression. M. tayal is very similar to M. satoyamanis but is distinguished by the following characters: the gonostylus is ca. three times longer than broad, instead of only ca. twice so; the apical part of the aedeagus is broad, about one half of the aedeagal width at the lateral shoulders, instead of being very narrow, ca. one sixth of the width at shoulders. Manota tayal is distinguished from both M. cristata and M. satoyamanis , in lacking two very long and strong setae ventrally on both sides of its hypoproct.

Etymology. The species is named after the Tayal people, a tribe of Taiwanese aboriginals, living near the type locality.
