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.
