Manota heptacantha sp. n.

( Figs. 1A, C ; 6D, E, F )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 6D . Maxillary palpus with palpomere 3 bearing 4–5 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Anepisternum setose. Anterior basalare setose. Preepisternum 2 non­setose. Laterotergite setose. Episternum 3 setose. Wing. Length 1.4–1.6 mm. Wing membrane dorsally with few setae at posterior margin. Sc distally of h non­setose. A1 indicated by 0 to few setae. Hypopygium ( Figs. 6E, F ). Sternite 9 large, laterally united with gonocoxa and posteriorly extending nearly as far as ventral part of gonocoxa; setosity similar to ventral setosity of gonocoxa. Gonocoxa dorsally in positions I–II with row of 7–12 megasetae with flattened rounded tips, no megasetae present in positions III and IV, in position III with rather strong normal seta, apicolateral part of gonocoxa simple, apicolateral setae of gonocoxa numerous, curved and rather strong, stronger than they appear in Fig. 6F . Gonostylus rather small, short to elongate­oval depending on angle of view, with some very strong setae apically and apicomesially and dorsally. Parastylar lobe present, directed posteriad, with several setae on apical part. Sternite 10 unusually large, extending nearly as far posteriorly as gonostylus, setae scattered.

Female and preimaginal stages unknown.

Discussion

Manota heptacantha is more or less similar to M. ulu . In both species there is a dorsal mesial row of setae on gonocoxa in positions I–II. In M. heptacantha , these setae are strong, blunt megasetae, whereas in M. ulu , they are only slightly strengthened, pointed setae. Furthermore, in M. heptacantha the apicolateral setae of the gonocoxa are normal, but are very strong and sigmoid in M. ulu . By having megasetae dorsomesially on the gonocoxa, M. heptacantha resembles M. biloba but is distinguished, for example, by the simple, not biramous, gonostylus.
