The subgenus Labidostoma is now overloaded with those species that share a regressive famulus on tarsi I: the Asian L. (L.) nepalense Feider and Vasiliu, 1968 , some South African species ( Bertrand and Theron, 1990 ) and some species from the Philippines (Bertrand and Corpus Raros, 1997). As a result, the subgenus Labidostoma ( Labidostoma ) looks like a ragbag. Notwithstanding, the recent discovery, in Iran , of a third species sharing the major distinctive character of the L. ( L. ) integrum and L. ( L. ) caucasicum sheds light on some uncertainties and attests that some "hard nucleus" of closely allied species exists. The new Iranian species offers the opportunity to reconsider these heterogeneities. It was of interest to confront the Iranian individuals to specimens collected from Western and Eastern parts of the distribution area of the closest species L. ( L. ) integrum .
