Manota duplex sp. n.

( Figs. 15D, E, F )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 15D . Maxillary palpus with palpomere 3 bearing 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 few setae at posterior margin. Sc distally of h non­setose. A1 indicated by no or few setae. Hypopygium ( Figs. 15E, F ). Sternite 9 large, extending posteriorly to nearly halfway along ventral length of gonocoxa, laterally sharply delimited, posterior margin confluent with more posterior membranous part with convex margin, setae similar to adjacent ventral setae of gonocoxa. Dorsomesial margin of gonocoxa simple, with weak lobes, without megasetae, in position III with 2 sigmoid simple setae arising from common basal body that is as long as setae, in position IV with few setae on long clavate basal body, roundish lobe with long setae near base of latter; gonocoxa apicolaterally with strong setae. Gonostylus long and narrow, curved especially on apical part. Parastylar lobe present, directed obliquely posteriad, with 3 apical setae. Tegmen short and broad, subtriangular, with weak lateral shoulders, which in some slides are not visible at all. Setae on sternite 10 in small oval patch (lobe) on each half.

Female and preimaginal stages unknown.

Discussion

Manota duplex is reminiscent at least superficially of M. perpusilla , especially in the apicodorsal structures of the gonocoxa. The long, curved, not elongated, oval gonostylus; posteriorly directed parastylar lobe; and strong, apicolateral setae of the gonocoxa distinguish M. duplex . For further discussion, see under M. perpusilla . The gonostylus of M. duplex is rather similar to that of M. curvata , but otherwise the species are abundantly different. The clavate lobe at the apex of the gonocoxa is certainly homologous with a similar lobe in M. perpusilla , the triangular posteriorly­directed lobe with that in M. acutangula and similar species, and the transverse lobe with that in species such as M. horrida and M. plusiochaeta .
