Manota inflata sp. n.

( Figs 1 E, F, 13 A, B, C)

Male. Colour. Head pale brown, frons, vertex, occiput and antennal flagellum darker brown, mouthparts pale yellowish. Thorax pale brown, posterior part of scutum, scutellum and part of mediotergite darker brown, pro- and mesothoracic pleura paler brown. Legs pale yellowish, femur 3 slightly infuscated on apical third. Wing unicolorous pale brown; haltere pale brown with dark brown knob. Abdomen brown. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 13 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 3–6 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 10–12. Thorax. Anepisternum setose, with 34–72 setae, anterior basalare non-setose, preepisternum 2 setose, with 11–28 setae, laterotergite non-setose, episternum 3 setose, with 4–20 setae. Wing. Length 1.8–2.1 mm. Hypopygium, Figs 13 B and C: Sternite 9 large, nearly as long as the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin convex or acuminate, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa convex. Parastylar lobe rather small, partly covered by the mesial margin of gonocoxa, subtriangular in shape so that the apex with two setae is directed obliquely anteriad. Paraapodemal lobe well exposed in ventral view, unusually large, globular. Dorsal mesial margin of gonocoxa simple except for a rather small setose lobe subapically. Gonocoxa with an apicolateral lobe with a few setae at mesial margin, the basal part of apicolateral lobe in dorsal view partly covered by the subapical lobe on the mesial margin. Two juxtagonostylar setae present, one being a strong but otherwise unmodified seta, the other a slightly longer apically curved megaseta, both setae arising from a common basal body which is about half the length of the setae. Gonostylus with a broad basal and narrow apical part, the setae unmodified, moderately long, very long at mesial margin. Tegmen subtriangular with strong lateral shoulders. Hypoproct posteriorly scarcely reaching the middle of gonostylus, with some 15 setae on each half. Cerci medially united except for the apical parts.

Female. Similar to male. Antennal flagellomere 4, Fig. 1 E. Palpomere 3 with 5 apically expanded sensilla. Anepisternum with 54–66 setae, preepisternum 2 with 24–30 setae, episternum 3 with 9–11 setae. Wing length 1.9–2.1 mm. Tip of abdomen, Fig. 1 F: Cercus two-segmented.

Discussion. Manota inflata is similar to a number of other Oriental Manota which have a non-setose laterotergite, more or less sickle-shaped oblique parastylar lobe, two long unequal juxtagonostylar setae arising from a long common basal body, and an apicolateral setose lobe on the gonocoxa. It is distinguished from all of these by the very large globular paraapodemal lobes, which are very conspicuous. Among these species, the gonostylus resembles that of M. plusiochaeta Hippa but is more strongly widened on basal half, has the setae at the mesial margin less distinctly in a row and lacks a group of short, thick, black setae apicodorsally. The female may be impossible to distinguish from similar species by the known characters. The two females mentioned above have been associated to M. inflata because they were caught together with males that they resemble. Females probably belonging to other species occur in the same samples.
