Pheidole kusnezoviHNS, new name

Eriopheidole symbiotica KusnezovHNS 1952d ("1951"): 16. Combination with PheidoleHNS by Brown 1973b: 180, creating an unresolved junior homonym of Pheidole symbiotica WasmannHNS 1909a: 515, now resolved with the new name kusnezoviHNS.

types Inst. Miguel Lillo, Tucuman; Mus. Comp. Zool. Harvard.

Etymology Named after N. Kusnezov, Argentinean entomologist who discovered the species.

diagnosis A permanent, workerless social parasite of Pheidole obscuriorHNS. The queen is very small in size, with slender head and large eyes, mostly shiny body surface, subangular petiole in side view, and hexagonal postpetiolar node seen from above. Overall, it has not evolved any of the extreme parasitic traits of other socially parasitic PheidoleHNS such as acutidensHNS, argentinaHNS, and elecebraHNS. measurements (mm) Queen: HW 0.64, HL 0.64, SL 0.78, EL 0.24, PW (not measured).

color Queen: appendages, anterior half of the head, and most of the sides of the mesosoma yellow; rest of head and body a contrasting light brown.

Range Known only from the type locality.

Biology Kusnezov's (1952a) field and laboratory research showed that Pheidole inquilinaHNS is a workerless inquiline of P. obscuriorHNS. He correctly pointed out that the queen represents an early stage of the kind of degenerative anatomy that characterizes ant inquilines in general.
