Comments.
The original description of this species was based on two females. The
holotype
is on two slides, one with one antenna and one fore wing under a large coverslip, and the rest of the body (head detached from mesosoma, and the antenna detached from head) on another slide under a small coverslip.
Hayat (2008)
noted that one female (on slide) labelled as ‘Paratype’ has the collection date ‘
2.2.1985
’ different from the collection date of the
holotype
(
9.v.1985
), whereas the author say that the
paratype
has the ‘same data as the holotype’. Therefore,
Hayat (2008)
considered this specimen as a non-type specimen.
Oligosita longirhinaria
appears similar to
O. hawaiina
Viggiani (1981)
, but differs from the latter in having the
