Manota plusiochaeta sp. n.

( Figs. 17A, B, C, D )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 17A . 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 1.4–1.6 mm. Wing membrane dorsally with few setae at posterior margin. Sc distally of h non­setose. Setae indicating A1 from none to few. Hypopygium ( Figs. 17B, C, D ). Sternite 9 large, extending posteriorly over half ventral length of gonocoxa, laterally sharply delimited, posterior margin sharply demarcated, rounded, setae subequal to adjacent ventral setae of gonocoxa, posteriorly couple of stronger setae on each side. Dorsomesial margin of gonocoxa simple, apical structures simple, with inconspicuous mesially directed setose transverse lobe covered by more dorsal part of gonocoxa, 2 long sigmoid megasetae in position III, arising from common basal body, no other megasetae. Gonostylus elongate­oval with characteristic strong marginal setosity on mesial side, apicodorsally with characteristic transverse crest with strong setae (marked in Fig. 17B ). Parastylar lobe present, directed obliquely anteriad, with 1 to few apical setae. Tegmen of medium length, subtriangular, with weak lateral shoulders. Setae on sternite 10 in row on each half.

Female and preimaginal stages unknown.

Discussion

Manota plusiochaeta is similar to M. oligochaeta but is distinguished by its gonostylus, which is much longer and which has about 10 long setae on the basal half of the mesial margin instead of only about 5. Manota plusiochaeta is also similar to M. ovata , but the latter has a setose laterotergite. For further discussion, see under M. ovata .
