Manota kyushuensis sp. n.

Figs 3 A–D

Male. Colour. Head pale brown, frons, vertex and dorsal part of occiput darker brown. Mouthparts pale yellowish. Antenna brown, scapus, pedicellus, flagellomere 1 and ventral part of flagellomere 2 paler yellowish. Thorax brown, prothorax and wide vetral part of mesothoracic preepisternum 2 (katepisternum) paler brown to yellowish. Legs pale yellowish, apices of coxae and the apex of femur 3 infuscated. Wing unicolorous greyish-brown; haltere yellowish-brown with dark brown knob. Abdomen brown, sternites 1–4 paler than other parts. All the setosity pale, the thicker setae seeming darker, even black, than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 3 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. as long as palpomere 4. Number of strong postocular setae 13. Thorax. Anepisternum setose, with ca 50 setae, anterior basalare setose, with ca. 10 setae, preepisternum 2 non-setose, laterotergite setose, with ca. 30 setae, episternum 3 setose, with ca. 12 setae. Legs. Middle tibial organ lacking. Hind tibial organ lacking. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 basally extending to the level of the tip of R1, wing length 1.5 mm. Hypopygium, Figs 3 , B, C, D: Sternite 9 laterally fused with gonocoxa, extending posteriorly as far as the ventral posterior margin of gonocoxa, anterior margin with a shallow incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe subquadrangular, divided into two parts by a ventral transverse crest, with 1–3 setae at posterior margin. Paraapodemal lobe not identifiable. Tergite 9 membranous, the anterior margin somewhat sclerotized and discernible. Dorsal mesial margin of gonocoxa sinuous, subapically with a stout, blunt megaseta. At the dorsal mesial margin of gonocoxa, on more ventral level, a plate-like lobe with ca. 10 blunt megasetae at its mesial margin. One juxtagonostylar seta present: a flattened subtriangular megaseta arising from a stout basal body which is about as long as the megaseta. Gonostylus rather small, apically bilobed; the ventral side setose, the dorsal side nonsetose except for apicolaterally and for the claw-like setae on the more dorsal one of the apical lobes, the mesial margin of the more ventral one of the apical lobes with three prominent strong setae. Aedeagus with a broad basal part and narrow parallel-sided apical part separated by strong lateral shoulders; the apex curved ventrad. Hypoproct large, posteriorly extending as far as the apex of gonostylus, with ca. 30 scattered setae on each half. Cerci mesially separate.

Female unknown.

Discussion. Manota kyushuensis belongs to a specious group, distributed in Afrotropical, Australian, Neotropical and Oriental regions, characterized by a large sternite 9 which posteriorly extends to the level of the gonostylar base and laterally is fused with the gonocoxa. Manota kyushuensis is similar to M. flammula and M. obtecta , both known from Thailand, and M. curvistylus sp. n by having one conspicuous megaseta subapically at the dorsal mesial margin of gonocoxa instead of having two or more or lacking megasetae at that position. Manota kyushuensis is similar to M. flammula by having the narrow megaseta parallel-sided, not expanding from narrow base to broad flat apical part. Manota kyushuensis is distinguished from M. flammula by the following characters: 1) the parastylar lobe has ventrally a transverse crest-like lobe; in M. flammula the parastylar lobe is quite simple, 2) the two lobes at the apex of the gonostylus are small, subequal in size, the length of the more dorsal and lateral one being about one third of the subbasal width of gonostylus, in M. flammula the more ventral and mesial one of the lobes is almost indistinguishable but the more lateral and dorsal one is very large, almost as long as the subbasal width of gonostylus, and 3) the aedeagus has strong lateral shoulders dividing it into a broad basal and narrow parallel-sided apical half; in M. flammula the aedeagus is subtriangular, without distinct lateral shoulders.

Etymology. The specific epithet is derived from the name of the type locality, Kyushu Island, by the Latin suffix - ensis, denoting place.
