Rhabdepyris luteipennis Evans, 1965

( Fig. 37–45 )

Rhabdepyris luteipennis Evans, 1965: 114 , 116, 117, 118–119; Gordh & Móczár, 1990: 148.

This species was known from Nicaragua, Panama, Trinidad and Brazil (Pará). Now, it is recorded for the first time from Amazonas of Brazil.

When Evans (1965) described this species he included two males, one from Panama and the other from Trinidad and Tobago, with the shape of mesopleural foveae very different from those of the allotype and rest of the series (state of Pará – Brazil and Nicaragua). In these specimens the upper foveae is long ( Fig. 38 ), about 0.6x as long as the lower fovea and also wide, and the lower fovea is large and just slightly constricted medially, whereas most of the other males including the allotype has the upper foveae short ( Fig. 39 ), about 0.25x as long as the lower fovea and triangular, and the lower fovea conspicuously constricted medially. Here we also observed these two patterns of mesopleural foveae in the specimens from Brazilian Amazon .

Besides, the specimens with large mesopleural foveae have mandible with four teeth ( Fig. 40 ), propodeal disc with paramedian carinae converging posteriorly ( Fig. 41 ) and notaulus very wide ( Fig. 42 ), whereas the specimens with small mesopleural foveae as the allotype have mandible with five teeth ( Fig. 43 ), propodeal disc with paramedian carinae diverging posteriorly ( Fig. 44 ) and notaulus not wide ( Fig. 45 ).

We believe that these patterns correspond to two different species as pointed out by Evans (1965), but it is not possible to know which one is the correct male for this species.
