Manota biloba sp. n.

( Figs. 6A, B, C )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 6A . Maxillary palpus with palpomere 3 bearing 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 mm. Wing membrane dorsally with few setae at posterior margin. Sc distally of h non­setose. Setae indicating A1 not observed. Hypopygium ( Figs. 6B, C ). 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 (similar to Fig. 8B ). Gonocoxa dorsally in position I with rounded lobe bearing 3 megasetae, in position II with 2 strong setae/megasetae ventrad of which there are 2 megasetae that may be those called position III megasetae, no megasetae in position IV; no prominent apical lobes. Gonostylus rather small, bilobed, with some strong setae, with very strong apical seta. Parastylar lobe present, directed posteriad, with about 4 unusually strong setae on apical part. Tegmen long, with strong shoulders. Sternite 10 unusually large, extending posteriorly nearly as far as gonostyli, setae scattered. Apical setae of cercus unusually strong.

Female and preimaginal stages unknown.

Discussion

Manota biloba is similar to M. clausa , M. heptacantha , M. ulu , and M. simplex but is easily distinguished by its bilobate or biramous gonostylus. It is also similar to M. globigera but has a non­setose laterotergite. For further distinguishing characters, see under M. globigera .

Manota biloba resembles several Afrotropical Manota , especially M. flavipes (Enderlein) from the Seychelles, but it has three megasetae on the gonocoxa in position I instead of only one (see Edwards 1928: Fig. 2a , and Matile 1972: Fig. 1 ). M. teocchi Matile from Central Africa may also be very similar. M. biloba differs from it, for example, by having three megasetae in position I instead of two. All the above­mentioned species have a general resemblance to the Afrotropical species M. serrata Söli and M. sespinea Söli , but have the position III seta less modified and the arrangement of the dorsal gonocoxal setae and megasetae very different. For further discussion, see under M. simplex .
