Manota pectinata sp. n.

( Figs. 11A, B, C )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 11A . 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 1.6–1.8 mm. Wing membrane dorsally with a few setae at posterior margin. Sc distally of h non­setose. A1 indicated by few setae. Hypopygium ( Figs. 11B, C ). Sternite 9 large, but extending posteriorly less than halfway along ventral length of gonocoxa, laterally sharply delimited, posterior margin distinct, confluent with more posterior membranous structures, setae similar to adjacent ventral setae of gonocoxa. Dorsomesial margin of gonocoxa apically with long slightly angulate lobe with row of strong marginal 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 long, narrow, slightly curved in outline. Parastylar lobe present, narrow, without distinct apex, its 2 setae directed transversely mesiad. Tegmen rather short and broad, subtriangular with concave sides, with distinct shoulders. Setae on sternite 10 in row on each half, parallel to sides of apical part of tegmen.

Female and preimaginal stages unknown.

Discussion

Manota pectinata is more or less similar to M. transversa , M. procera , M. calcarata , M. ferrata , and M. acutangula , especially to the latter species which it resembles by having a lobe on the dorsomesial angle of the gonocoxa. It differs from M. acutangula by having the gonocoxal lobe with a long edge armed with a comb­like row of setae; in M. acutangula the lobe is pointed and the setae are on its posterior margin. Manota pectinata also differs from M. acutangula by lacking the lobe on the mesial side of the gonostylus. Manota pectinata is also similar to M. orientalis but can be distinguished by lacking the two lobes mesially on the gonostylus that are present in that species (see Edwards 1928: Fig. 2a ).
