Ooencyrtus Ashmead

Remarks. Ooencyrtus contains 312 world species ( Noyes 2015). The two new species described here apparently belong to a group of species characterized by either a completely dark brown to black body, or the gaster basally (TI or from base to level of cercal plates) is yellow, orange yellow or brownish yellow in some species; antenna with the funicle segments clearly longer than broad, slightly more than 1.5× to at least 2× as long as broad; and mandible with one or two small teeth and a broad truncation. At least the following species also belong to this group: Ooencyrtus submetallicus (Howard) (see Noyes 1979), O. fecundus Ferrière & Voegele (1961) , O. nigerrimus Ferrière & Voegele (1961) , O. acastus Trjapitzin (1967) , O. gonoceri Viggiani (1971) , O. brunneipes ( Noyes 1978) , O. solidus Khlopunov (1981) , O. exallus Prinsloo (1987) , O. egeria Huang & Noyes (1994) , O. seronis Hayat, in Hayat et al. (2014) , O. telenomicida ( Vassiliev 1904) (see Trjapitzin 1989 and Huang & Noyes 1994).

We give a key to those species which are similar to the new species in having the fore wing with an oblique bare area below the parastigma (speculum?) proximal to the linea calva and the linea calva open posteriorly ( Fig. 6 ). In the remaining species listed above, the linea calva of the fore wing is either open or closed posteriorly, but without a bare area below the parastigma proximal to the linea calva.
