Eustenogaster luzonensis ( Rohwer, 1919)

Stenogaster micans var. luzonensis Rohwer, 1919: 3 a, 16.

Eustenogaster luzonensis is similar to E. palavanica , but, according to Reyes (1988), this species can be distinguished from E. palavanica by the larger punctures in the area just below the anterior ocellus and around posterior ocelli; and yellow spots above antennal socket, on vertex, second metasomal tergum, and on male mandible, all absent. The male of this species can be distinguished from other Eustenogaster species by the strongly swollen eyes ( Fig. 58 ). Male genitalia are similar to those of E. palavanica ( Figs. 59 L, X; 59K, W, for E. palavanica ), but the volsella is not projected ventrally ( Fig. 59 X).

Material examined. Philippines: Luzon; 1ɗ ( RMNH), 10.ix.1920, F4546.

Distribution: Philippines: Luzon.
