Lin & W. T. Yang, Malaise trap – NMNS ENT 3028–971 .

Measurements in mm: body length 2.64 (holotype), 2.28, 2.70 (paratype males), 2.47, 3.10 (paratype females), wing length 2.26, 2.00, 2.20 (paratype males), 2.28, 2.70 (paratype females), wing breadth ca. 0.85 (holotype), 0.85, not measurable, ca. 0.87 and 1.25 (paratypes).

Thorax mostly ochre, caudal part of thorax incl. scutellum and mediotergite diffuse brown (one of the female paratypes with almost completely dark thorax).

Eyes with evenly distributed medium-long hairs. Facial setae yellowish at middle, dark over clypeus and along eyes, or all facial setae dark. Postocellar setae black. Longest postocular setulae 0.065–0.09 mm. Scape, pedicel and flagellomeres dark. Flagellum of holotype ca. 1.25 mm long (much curved). Flagellomeral hairs dense, 0.025 mm, apically 0.035 mm long. Palpi white or whitish yellow, ca. 0.55 mm long on holotype, ca. 0.48 mm on one male, 0.75 mm long on one female paratype.

Anepisternum with dense hairs, katepisternum pilose on anteroventral part (badly visible), laterotergite bare. Scutellum with 2 pairs of long black marginal setae.

Wing light brownish with brown veins. Costal section from H to R 1 0.715 mm, from R 1 to R 5 1.01 mm, extant sections of M 1 0.485 mm (to wing margin), M 2 1.31 mm long. Halteres ochreous with blackish knob.

Legs yellow. Length of femur, tibia, first tarsomere and tibial spurs (in mm, measured on holotype): fore: 0.605, 0.46, 0.50, 0.34, mid: 0.95, 0.95, 0.57, 0.42, 0.32; hind: 1.05, 1.36, 0.605, 0.46, 0.39.

Abdomen dark brown, sternites 1–5 lighter. Postabdomen incl. segment 9 ochre. Tergite 9 longer than broad ( Fig. 13 ), apically with some longer thick setae. Sternite 9 ( Fig. 14 ) subtriangular, its setae are shorter but more numerous than on tergite 9.

0.2 mm for all

Cerci, which bear some minute black thornlets apically. Gonocoxite ( Figs 15–16 ) with a bulbous ventral lobe and with 2 long thick, apically curved black setae at the base of gonostylus ( Fig. 17 ). Gonocoxites close to each other. Gonostylus long, setose, bilobed ( Figs 15–17 ). Hypoproct with a pair of long but not thick setae and with several short setulae. Aedeagus short and triangular.

Female body and wing length probably slightly larger than in males (see above). Postabdomen ochre, cerci with evenly distributed hair-like setae not longer than 0.035 mm. The females were identified by the body colour and by the colour of facial and fore coxal setae.

M. bilobata sp. n. is easily separable from the other Taiwanese species of Manota by its black postocular setae and partly dark fore coxal setae. It belongs to that species-group of the true Manota , where the laterotergite is bare and the katepisternum is pilose (anepisternum is with dense hairs); in these respects it is similar to M. chinensis and M. delyorum . The distinctive features are in the male genitalia: The gonocoxite has only 2, not particularly thick megasetae near gonostylar base (cf. SØLI 1993), and the gonostylus is bilobed with both lobes bearing longer setae.
