Male.
Head.
Flagellomere 4,
Fig. 5A
. Maxillary palpus with palpomere 3 bearing 4–6 apically expanded curved sensilla; palpomere 4 with parasegment.
Thorax.
Anepisternum setose. Anterior basalare nonsetose. Preepisternum 2 setose. Laterotergite setose. Episternum 3 setose.
Wing
. Length
1.4–1.5 mm
. Wing membrane dorsally with few setae at posterior margin. Sc distally of h nonsetose. Setae indicating A1 from few to many.
Hypopygium
(
Figs. 5B, C
). 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 subapical setose transverse lobe covered by mesial margin, with 2 long sigmoid megasetae in position III, arising from common basal body. Gonostylus elongateoval with characteristic marginal setosity on mesial side. Parastylar lobe well exposed, directed obliquely anteriad, with couple of apical setae. Tegmen rather short, triangular, with slight lateral shoulders. Setae on sternite
10 in
densely placed patch or in 2 short rows near apex of tegmen.
Female and preimaginal stages unknown.
Discussion
Manota ovata
resembles
M. plusiochaeta
and
M. oligochaeta
, but has the laterotergite setose. Furthermore, it can be distinguished from both by the roughly oval outline of its gonostylus and by having the setae on sternite
10 in
a short tworowed group rather than in one row.
Manota ovata
is similar to
M. angustata
from which it differs by the simple ovate gonostylus. In
M. angustata
the gonostylus is narrow, parallelsided and with an apicomesial lobe.
