Cyphomyrmex rimosus (Spinola)


16. Cyphomyrmex rimosus (Spinola)   HNS  

Cyphomyrmex rimosus   HNS   , presently taken as a polytypical species, is both the commonest form in the genus and at the same time a residue of classification. The puzzling variability of the complex, which gave rise to a number of infraspecific names in the past, needs a special study, not possible at this time.

Yet I must point out that the infraspecific arrangement for rimosus   HNS   , as proposed at the beginning of this paper, does not imply a judgement upon the validity of the actually recognized 11 morphs and 6 synonyms. It only serves the purpose of keeping track of these names.

The separation of hamulatus   HNS   , salvini   HNS   and transversus   HNS   as full species, and the return of cochunae   HNS   and venezuelensis   HNS   to the rimosus   HNS   complex are novelties. The former step, i. e. the raising of the three "races" to specific category seems to be justified by morphological and distributional considerations; cochunae   HNS   , elevated to species level by Kusnezov (1957) does not deserve this rank being probably just a synonym of one of the previously described morphs of rimosus   HNS   ; venezuelensis   HNS   did not prove a synonym of transversus   HNS   , as proposed by Weber (1958), and was put back under rimosus   HNS   awaiting clarification of its true status.
