Manota angustata sp. n.

( Figs. 1E ; 5D, E, F )

A small­sized Manota .

Male. Head. Flagellomere 4, Fig. 5D . 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. Front leg, Fig. 1E . Wing. Length 1.3–1.5 mm. Wing membrane dorsally with few setae at posterior margin. Sc distally of h non­setose. Setae indicating A1 not observed. Hypopygium ( Figs. 5E, F ). Sternite 9 large, laterally sharply delimited but posterior margin weakly indicated, setae subequal to ventral setae of gonocoxa. Dorsomesial margin of gonocoxa simple, without apicolateral triangular lobe but with small subapical mesial rounded lobe covered by mesial margin, with 1 long sigmoid megaseta and 1 shorter less sigmoid one in position III, both arising from long common basal body; in 1 paratype, the difference between these 2 setae is not as great as in Fig. 5E , but the shorter one, too, is curved in the apical part. Gonostylus elongate, parallel­sided, with subapical process on the mesial side. Parastylar lobe well exposed, directed obliquely anteriad, with 1 apical setae. Tegmen rather short, triangular, with slight lateral shoulders. Setae on sternite 10 about 7 in number, in scattered row extending anteriorly to level of apical part of tegmen.

Female and preimaginal stages unknown.

Discussion

Manota angustata is similar to M. ovata , but is distinguished by its narrow parallelsided gonostylus with a mesial subapical lobe.
