Treatment

Pseudomyrmex acanthobius (Emery View in CoL HNS 1896b).

Pseudomyrma acanthobia Emery HNS 1896b: 628. [w syntypes examined, MCSN, MHNG; Paraguay (Bohls)] .

Pseudomyrma acanthobia var. fuscata Emery HNS 1896b: 629. NEW SYNONYMY. [w syntypes examined, MCSN, MHNG; Paraguay (Bohls)] .

Pseudomyrmex acanthobius (Emery) HNS . Kusnezov 1953: 214.

Pseudomyrmex acanthobius var. fuscatus (Emery) HNS . Kempf 1972: 215.

Pseudomyrmex acanthobius HNS , a small pallidus-group species with large eyes and a relatively swollen fore femur, has been recorded sporadically from Paraguay nesting in Acacia HNS thorns. Emery described both P acanthobius HNS and P. acanthobius var. fuscatus HNS in the same paper (Emery 1896b), distinguishing the two forms on the basis of color. The collections I have seen of this species can vary from orange-yellow to dark brown. Phil Ward, who is currently revising Pseudomyrmex HNS , has examined Emery’s types and my recent Paraguayan collections and concluded that the color variation is intraspecific. As there are no other characters that reliably differ between the forms, I see no reason to dissent from Ward’s assessment.
