Manota bicuspis

sp. n.

Manota bicuspis  sp. n.

( Figs 1View FIGURE 1 E, 17 A –C)

A small-sized Manota  .

Male. Coloration. Pale yellowish-brown, frons, vertex and occiput and abdominal tergites darker brown, mouthparts and legs slightly paler than thorax, wing unicolorous, almost colourless, knob of haltere dark. Head. Antennal flagellomere 4, Fig. 17View FIGURE 17 C. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Pleural setosity pattern, Fig. 1View FIGURE 1 E: anepisternum setose, with 48–58 setae; anterior basalare non-setose; preepisternum 2 setose, with 16–25 setae; laterotergite setose, with 18–28 setae; episternum 3 setose, with 8–11 setae. Wing. Length 1.8 mm. Hypopygium ( Figs 17View FIGURE 17 A, B). Sternite 9 extending posteriorly near to the level of the gonostylar base, laterally sharply delimited, posterior margin convex, medially acuminate, anterior margin deeply incised, the setae similar to adjacent ventral setae of gonocoxa. Parastylar lobe well exposed in ventral view, with a large lobe directed obliquely posteriorly and an indistinct lobe-like expansions at base, with one seta at the apex of the large lobe and two setae more basally on the dorsal side of that lobe, one of these two setae more proximal and one more apical. Paraapodemal lobe exposed in ventral view, not shown in Fig. 17View FIGURE 17 B, similar to M. parilis  , Fig. 18View FIGURE 18 A. The dorsal mesial margin of gonocoxa with a large rounded setose lobe at the middle and a large broad lobe apically with a few rather strong setae on mesial margin and with two or three long setae arising from the ventral surface; the latter lobe similar to that in M. hamulata  , Fig. 16View FIGURE 16 B, but in Fig 17View FIGURE 17 A it is turned so that the ventral side is exposed. Two juxtagonostylar setae present, a curved megaseta and a strong seta, both arising from a common basal body which is longer than the megaseta, the megaseta at the apex of the basal body, the seta more basal in position. Gonostylus laterally flattened with the dorsal and ventral surfaces very narrow, in lateral view the gonostylus subtriangular with a narrow basal part and broad apical part, the apicodorsal margin weakly lobed, the setae on dorsal, lateral and ventral faces similar to ventral hairs of gonocoxa, the apical margin of gonostylus with a row of setae directed mesad with the two most dorsal of the setae distinctly thicker than the others and arising from a small lobe, the mesial face of the gonostylus non-setose and without prominent microtrichia. Tegmen elongate-triangular, without distinct lateral shoulders. Hypoproct posteriorly extending to the level of the base of gonostylus, with ca. 20 long scattered ventral setae on each half. Cerci medially separate.

Female and preimaginal stages unknown.

Discussion. M. bicuspis  is similar to M. hamulata  and M. parilis  . For the distinguishing characters, see under the two latter.
