Manota confixa sp. n.

( Figs 8 A, B, C)

Male. Colour. Head pale brown, frons and occiput darker brown, mouthparts pale yellowish. Thorax pale brown, preepisternum 2 ventrally paler yellowish. Legs pale yellowish, femur 3 infuscated on apical third. Wing unicolorous yellowish-brown; haltere yellowish-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. 8 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 10. Thorax. Anepisternum setose, with 40 setae, anterior basalare setose, with 6 setae, preepisternum 2 non-setose, laterotergite setose, with 20 setae, episternum 3 setose, with 6 setae. Wing. Length 1.7 mm. Hypopygium, Figs 8 B, C and D: Sternite 9 laterally fused with gonocoxa, extending posteriorly as far as the ventral posterior margin of gonocoxa, anterior margin shallowly incised, the setae similar to ventral setae of gonocoxa. Parastylar lobe large but rather narrow, with 2–3 setae at mesial margin (apically). Paraapodemal lobe absent. Dorsal mesial margin of gonocoxa simple, arcuate, the mesial margin partly covering a more ventrally lying plate-like lobe bearing 12 blunt-ended megasetae on margin and on ventral side. Gonocoxa with a distinct curved apicolateral lobe with a few setae dorsally and at apex and extending posteriorly as far as apex of gonostylus. One juxtagonostylar seta present, which is an unmodified megaseta lacking a distinct basal body. At the juxtagonostylar seta there is a finger-like lobe. Gonostylus oval with a slightly expressed apico-lateral lobe, with rather short unmodified setae ventrally, largely non-setose dorsally, with a group of prominent long setae at mesial margin. Tegmen characteristic in shape, with prominent lateral shoulders, with the narrow apical part rather short and the broader basal part narrowing anteriad. Hypoproct large, extending posteriorly over the apex of gonostylus, with some 25 setae on each half. Cerci medially separate.

Female unknown.

Discussion. M. confixa is similar to M. juncta sp. n. It differs from the latter e.g. by the following characters: 1) the narrow apical part of tegmen is short, about one-third of the length of the tegmen, instead of being more than half of the length, 2) the tegmen is narrowed at base instead of being broadest at base, 3) the posterior margin of sternite 9 is convex, not slightly concave, 4) there is a hyaline finger-like lobe at the base of the juxtagonostylar seta, 5) there is a hyaline lobe mesially at the apex of the apicolateral lobe of gonocoxa, 6) the dorsal mesial margin of the gonocoxa at the megasetae-bearing lobe is gently curved instead of being more angularly curved. M. confixa and M. juncta resemble M. dentata Hippa and Papp and M. heptacantha Hippa but differ e.g. by having the megasetae-bearing lobe at the dorsal mesial margin of gonocoxa shorter and placed on the apical half of gonocoxa instead of extending to its basal half, and by having the gonocoxal apodemes in a more posterior position. M. confixa and M. juncta have also the gonostylus produced slightly lobelike apicolaterally, unlike the other two species.
