Manota phyllochaeta sp. n.

( Figs 7 A, B, C)

Male. Colour. Face yellowish-brown, frons, vertex and occiput darker brown, antennal scapus and pedicellus concolorous with face, antennal flagellum brown, flagellomere 1 basally paler, mouthparts pale yellowish. Thorax pale brown, prothorax and ventral part of preepisternum paler than the other parts. Legs pale yellowish, trochanter 2, apparently also trochanter 3, and basal third of femur 3 infuscated, femur, tibia and tarsus of legs 1 and 2 lost from the single specimen. Abdomen brown. Postocular setae dark brown, nearly black, all other setosity pale yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 7 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 unusually narrow apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 10. Thorax. Anepisternum setose, with 40 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite setose, with 19 setae; episternum 3 setose, with 6 setae. Wing. Length 1.8 mm. Hypopygium, Figs 7 B, C: Sternite 9 laterally fused with gonocoxa, extending posteriorly to base of gonostylus, posterior margin nearly straight, anterior margin notched, the setae similar to ventral setae of gonocoxa. Parastylar lobe directed posteriad, long and narrow, with an apical seta in line with lobe. Paraapodemal lobe not observable. Original course of dorsal mesial margin of gonocoxa not seen because the mesial side is inflated on both sides in the single specimen; near middle between gonocoxal apodeme and apicolateral lobe with an angulate plate-like lobe on the ventral side of which are two blunt-ended stout megasetae, each of them arising from a small basal body. Gonocoxa with distinct apicolateral lobe extending posteriorly nearly as far as apex of gonostylus. It is laterally setose and has a couple of apical setae. One juxtagonostylar seta present: it is apparently similar to Fig. 2 E, but in Figs. 7 B and C it is seen in the narrow aspect; the basal body of the seta is about two-thirds of its length. Gonostylus narrow, tapering towards apex, with a lobe-like mesial widening on basal half; ventrally with a few short setae and one long outstanding seta on basal half; mesial margin with a few setae, three of which at the lobe are long and outstanding; two truncate setae at apex, one apical, the other subapical; dorsal side non-setose. Tegmen with a narrow apical half and subtriangular basal half, without distinct lateral shoulders. Hypoproct large, posteriorly extending as far as apex of gonostylus, with ca. 30 setae on each half, the setae in rather distinct, more anterior and more posterior groups. Cerci medially separate.

Female. Unknown.

Discussion. M. phyllochaeta is similar to M. flavipes (Enderlein) , M. clinochaeta sp. n. and M. teocchi Matile. For distinguishing characters, see under M. flavipes and M. clinochaeta . Types.
