Manota acutangula sp. n.

( Figs. 11D, E, F )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 11D . Maxillary palpus with palpomere 3 bearing 4–5 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Anepisternum setose. Anterior basalare non­setose. Preepisternum 2 setose. Laterotergite non­setose. Episternum 3 setose. Wing. Length 1.5–1.8 mm. Wing membrane dorsally with few setae at posterior margin. Sc distally of h non­setose. A1 indicated by few setae. Hypopygium ( Figs. 11E, F ). Sternite 9 large, extending posteriorly to halfway along ventral length of gonocoxa, laterally sharply delimited, posterior margin indistinct, confluent with more posterior membranous structures, setae similar to adjacent ventral setae of gonocoxa. The dorsomesial margin of gonocoxa apically strongly and sharply angled, with normal setae, in position III with 2 curved simple megasetae arising from common long basal body; gonocoxa apicolaterally with long, tapering, mesially setose, subtriangular lobe. Gonostylus elongate­oval in outline with wide lobe on mesial side, lobe dorsally on apical side with 2 oblique rows of strong setae. Parastylar lobe present, directed anteriad, with 2 apical setae. Tegmen rather short and broad, subtriangular with concave sides. Setae on sternite 10 in long row on each half, mostly posteriorly of apex of tegmen.

Female and preimaginal stages unknown.

Discussion

Manota acutangula is more or less similar to M. transversa , M. procera , M. calcarata , M. ferrata , and M. pectinata . It differs from all these by the acutely angulate dorsomesial corner of the gonocoxa and by having a broad lobe­like widening on the mesial side of the gonostylus. Manota acutangula also resembles M. orientalis but differs by having one large lobe mesially on the gonostylus instead of two small ones and by having the dorsomesial corner of the gonocoxa acutely angulate instead of having a narrow rectangular lobe (see Edwards 1928: Fig. 2a ).
