Manota bracteata sp. n.

Figs 5 A–D

Male. Colour. Head brown, face paler brown. Antenna brown. Mouthparts paler yellowish. Thorax brown, preepisternum 2 ventrally pale. Legs pale yellowish, trochanters 2 and 3 brown, apical third of femur 3 infuscated, the basal part of femur 2 and 3 slightly infuscated. Wing brownish; haltere pale brown with dark brown knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 5 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.5 times longer than palpomere 4. Number of strong postocular setae 8. Thorax. Anepisternum setose, with 36–43 setae; anterior basalare setose, with 12 setae; preepisternum 2 non-setose; laterotergite setose, with 20–28 setae; episternum 3 setose, with 23–15 setae. Legs. Mid and hind tibial organs absent. Wing. R1meeting C well on the basal half of the costal margin; the sclerotized part of M2 basally extending to the level of the tip of R1, wing length 1.7 mm. Hypopygium, Figs 5 B–D: Sternite 9 as long as the ventral length of gonocoxa, laterally fused with gonocoxa, posterior margin slightly convex, anterior margin without medial incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe subtriangular with three setae at apical margin. Paraapodemal lobe not identifiable. Dorsal mesial margin of gonocoxa largely membranous, the posterodorsal part of gonocoxa forming a broad slightly curved lobe with a row of setae at the middle, with a few longer setae at the apex and a row of three flat scale-like megasetae at apicomesial margin. At the dorsal mesial margin of gonocoxa, on more ventral level with a plate-like lobe bearing three blunt megasetae. One juxtagonostylar seta present, which is a flattened but apically pointed megaseta arising from a curved basal body which is as long as the megaseta. Gonostylus slightly longer than half of the ventral length of gonocoxa, bilobed, with a longer elongate subtriangular ventral part and a shorter curved dorsal part; the setae on the ventral side similar to those on the gonocoxa, the dorsal side non-setose, at the apex of the ventral lobe two stronger setae deviating from the other setosity, at the apex of the dorsal lobe with two weaker setae. Aedeagus especially elongate subtriangular, without lateral shoulders, the apex curved ventrad. Hypoproct large, posteriorly extending near to the apex of gonostylus, with ca. 70 scattered setae on each half, the setae divided into an anterior and a posterior group of ca. 50 and ca. 20 setae. Cerci mesially separate, the setae distributed from apex near to base, the longest setae about 3 times longer than the subapical width of cercus.

Female unknown.

Discussion. Manota bracteata belongs to a group with 4 other species— M. cultrigera , M. foliolata , M. pinnata and M. pinnulata —which have: 1) sternite 9 laterally fused with the gonocoxa, 2) a large hypoproct, 3) a megasetae-bearing lobe at the dorsal mesial margin of the gonocoxa and 4) two or more flattened leaf- or scale-like megasetae posteriorly at the dorsal mesial margin of gonocoxa. M. bracteata resembles M. pinnata by having a row of three of these flattened setae which are short with rounded apices while they are long, sigmoidal and pointed in M. pinnata . Further, M. bracteata has three megasetae close together on the lobe at the dorsal mesial margin of the gonocoxa, in M. pinnata they are placed in pattern 1+2 on a sclerotized horse-shoe shaped part. Compared to M. pinnata , M. bracteata has the gonostylus more deeply bilobed and the posterior part of the hypoproct is not narrowed ( Figs 5 B, D). For further discussion, see under M. pinnata .

Etymology. The name is Latin, bracteata , with small scales, referring to the scale-like megasetae posterodorsally on the gonostylus.
