Manota planilobata sp. n.

( Figs 19 A, B, C, D)

Male. Colour. Head pale brown, frons, vertex and occiput darker brown, 2 basal antennal flagellomeres ventrally and apical part of flagellomere 14 paler than rest of flagellum, mouthparts pale yellowish. Thorax pale brown, ventral part of preepisternum 2 paler than the other parts. Legs pale yellowish, coxae 2 and 3 infuscated at tips and their respective trochanters infuscated, other parts of legs 2 and 3 lost in the single specimen. 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. 19 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 12. Thorax. Anepisternum setose, with 27 setae, anterior basalare setose, with 4 setae, preepisternum 2 setose, with 18 setae, laterotergite non-setose, episternum 3 setose, with 11 setae. Wing. Length 1.7 mm. Hypopygium, Figs 19 B and C: Sternite 9 about one-half of the ventral length of gonocoxa, lateral margin sharply delimited, contiguous with the rounded, deeply medially cleft posterior margin, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple. Parastylar lobe large, with numerous setae at posteromesial margin. Paraapodemal lobe distinct, well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, convex at middle, with a small subapical lobe with a couple of setae, and just posterior of it with a small lobe with a strong seta; on apical half of gonocoxa, situated ventrad from the dorsalmost margin, with a plate-like lobe bearing 5 strong setae. Two juxtagonostylar setae present, both being curved megasetae but greatly unequal in size and both arising from a low common basal body. Gonostylus simple, elongate-quadrangular, both ventral and dorsal side with moderately long unmodified setae, the apicomesial angle with two and the mesial margin with one strong seta differing from the other setosity. Tegmen subtriangular, with weak lateral shoulders, the apical tube directed posteriad. Hypoproct extending posteriorly to the base of gonostylus, with some 15 setae on each half, the mesialmost setae in an oblique row, a few setae forming an indistinct lateral group. Cerci medially separate.

Female unknown.

Discussion. M. planilobata is similar to M. collina sp. n. For further discussion, see under the latter.
