description: Manota yaeyamaensis sp. n.
Figs 7 A–D
Male. Colour. Head pale brown, frons and vertex darker brown. Antenna pale brown, scapus, pedicellus and ventral part of flagellomeres 1–4 paler yellowish. Mouthparts pale yellowish. Thorax brown, dorsally darker than laterally, prothorax and mesothoracic preepisternum 2 (katepisternum) paler than the other parts. Legs pale yellowish-brown, femur 2 and 3 infuscated at base. Wing unicolorous pale greyish-brown; haltere pale yellowish-brown with dark brown knob. Abdomen brown, sternites 1–5 paler than the other parts. All the setosity yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia, the thickest ones seeming black. Head. Antennal flagellomere 4, Fig. 7 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 1.2–1.4 times as long as palpomere 4. Number of strong postocular setae 10. Thorax. Anepisternum setose, with ca. 45 setae, anterior basalare nonsetose, preepisternum 2 setose, with ca. 15 setae, laterotergite non-setose, episternum 3 setose, with ca. 15 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 1.8–2.2 mm. Hypopygium, Figs 7 B, C, D: Sternite 9 about half ventral length of gonocoxa, with sharply delimited convex lateral margin, posterior margin broadly concave, anterior margin deeply incised medially; the setae of sternite 9 similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa shallowly sigmoid. Parastylar lobe sickle-shaped, with two transverse setae at anterior end. Paraapodemal lobe prominent, well exposed in ventral view. Tergite 9 membranous, the basal margin somewhat sclerotized and discernible. Dorsal mesial margin of gonocoxa simple, only slightly convex, the posterior part forming a finger-like setose lobe. Number of juxtagonostylar setae 2, both rather weakly modified curved long megasetae, one pointed, the other blunt, and both arising from a finger-like basal body which is about half the length of the megasetae. Gonostylus of normal size, elongate oval, ca. 2.5 times longer than broad; the ventral side setose with the setae similar to gonocoxa, the setae at the apicomesial margin longer than the others, the dorsal side nonsetose except for a double row of short curved setae on a transverse crest-like lobe on the apical half. Aedeagus subtriangular, without prominent lateral shoulders, the apex curved ventrad. Hypoproct posteriorly reaching just over the base of gonostylus, with a longitudinal row of ca. 10 setae on each half. Cerci medially separate.
Female unknown.
Discussion. Manota yaeyamaensis belongs to a group of species, very specious in the Oriental region, characterized by the following characters: anepisternum and preepisternum 2 setose, laterotergite nonsetose, sternite 9 laterally separated from the gonocoxa, parastylar lobe sickle-shaped with a few setae at the anterior end, gonocoxa dorsally with an apical (posterior) setose projection, juxtagonostylar megasetae simple (not flattened), and the ventral setae on the hypoproct in two longitudinal rows. In its hypopygium M. yaeyamaensis resembles M. acutangula Hippa, 2006 in particular. In both species the shape of the gonostylus is similar and there is a transverse setose crest dorsally on its apical half. Manota yaeyamaensis is distinguished from M. acutangula and other reminiscent species by its setose anterior basalare, from M. acutangula also by lacking an angular lobe posteriorly on the dorsal mesial margin of the gonocoxa, at the base of the apical lobe.
Etymology. The specific epithet is derived from the type locality, Yaeyama Islands, by the Latin suffix - ensis denoting place.
