Remarks. The identification of this species has not been possible due to the uncertainty of the differences between several very similar species, i.e., alatus , facialis , jagdishi , mustelinus , niger , undulatus and varicolor . Based on the variation found in our material, considered to be a single species, some or all of these previously described forms may prove to be synonyms.
