Comments.
The original description of this species was based on a single female. The
holotype
is on two slides, one slide with one antenna and fore wing under a large coverslip, and the rest of the body (head partly damaged; mesosoma and metasoma somewhat crushed) on another slide under a small coverslip.
This species appears to be very similar to
O. macrothoracica
Lin (1994)
, but differs from the latter in having the fore wing with different setation (
Fig. 2
) and about 4× as long as broad, and the clava about 3.6× as long as broad. In
O
.
macrothoracica
the fore wing is 3× as long as broad and the clava 4.6× as long as broad.
