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
