Manota pollex sp. n.

( Figs. 4C, D )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 4C . 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 setose. Episternum 3 setose. Wing. Length 1.7 mm. Wing membrane dorsally with few setae at posterior margin. Sc distally of h non­setose. A1 indicated by few setae. Hypopygium ( Fig. 4D ). Sternite 9 short, one­fourth of ventral length of gonocoxa, laterally sharply delimited, posterior margin not clearly contiguous so that sternite gives impression of being medially divided, setae stronger than ventral setae of gonocoxa. Gonocoxa ventrally with rounded lobe apicomesially, lobe with stronger setae deviating from adjacent setosity; dorsally in position I with rounded lobe bearing 1 megaseta, 1 flattened megaseta in position III which basally may have a branch, no apicolateral triangular lobe. Gonostylus elongate, laterally angularly convex, mesially nearly straight, apically almost pointed. Parastylar lobe lacking. Tegmen long and unusually narrow, with slight lateral shoulders. Setae on sternite 10 scattered.

Female and preimaginal stages unknown.

Discussion

Manota pollex is similar to M. yongi . It differs from the latter by having the group of stronger setae apicomesially on the ventral side of the gonocoxa on a small rounded lobe. Furthermore, the apical part of the gonostylus is less narrowed or pointed and the lobe dorsally on the gonocoxa in position I is narrower. Both species are rather similar to M. roslii . For further discussion, see under M. roslii .
