A revision of the Neotropical fungus-growing ants of the genus Cyphomyrmex Mayr. Part II. Group of rimosus (Spinola) (Hym. Formicidae). Author Kempf, W. W. text Studia Entomologica (N.

Cyphomyrmex championi Forel Cyphomyrmex championi Forel , 1899: 41, pl. 3, fig. 3 (Male; Panama: Volcano de Chiriqui). Type. - A lone male (holotype) collected by Champion, deposited in the British Museum (Natural History). Not being prepared for a critical study of Cyphomyrmex males, I gave this specimens only a perfunctory glance during my visit to the British Museum in August 1964. The specimen looks like a big rimosus male with comparatively huge frontal lobes. A future revision of the males of genus Cyphomyrmex will probably show that championi is the male caste of salvini Forel . The types of both species are from Panama, and both were described by Forel in the same paper.
