Species: Pogonomyrmex marcusi
Taxonomic history (from RAJ):
Pogonomyrmex marcusi Kusnezov, 1951: 260, fig. 13a (worker, in key). Syntypes examined: 1 worker [MCZ], 3 workers [USNM], Cochabamba, Bolivia; Marcus, 1953; 46, figs. 30-38 (larvae); Kusnezov, 1954: 83, figs. 1-4 (queen, male). See also Marcus and Marcus, 1951: fig. 8; Wheeler & Wheeler, 1960: 3.
Etymology: Kuznezov named this species after Dr. Harry Marcus, who apparently collected the syntypes and studied the ecology of this species. Kusnezov described P. marcusi in a key in his revision of the Pogonomyrmex of Argentina (Kusnezov, 1951), but he did not describe all three castes until Kusnezov (1954). During the interim, Marcus had completed two studies on the ecology of P. marcusi (see below).
