Pseudomyrmex goeldii

P. goeldii is known only from the type series collected more than a century ago in southeastern Brazil by Emílio Goeldi. The type locality (Sorocaba) is located within the Atlantic rainforest region. (Ward 2017)

Identification
Ward (2017) - This species is distinguished by the combination of relatively large size (HL 0.81–0.87, HW 0.65– 0.66), shiny puncticulate head, and weakly angulate juncture of the dorsal and declivitous faces of the propodeum. The eye appears to be shorter than in other members of the goeldii group (REL 0.55–0.56 versus 0.57–0.66 in other species; REL2 0.69–0.73 versus 0.75–0.87).

Worker
Ward (2017) - (n = 3). HL 0.81–0.87, HW 0.65–0.66, MFC 0.009–0.010, CI 0.76–0.80, REL 0.55–0.56, REL2 0.69–0.73, FCI 0.014–0.015, FI 0.49–0.53, PLI 0.51–0.59, PWI 0.48–0.56.

Larger species (HL 0.81–0.87, HW 0.65–0.66) in comparison with other members of the goeldii-group, with shorter eyes (see REL and REL2 indices); juncture between dorsal and declivitous faces of propodeum only weakly angulate; in profile anterodorsal face of petiole ascending about as steeply as posterodorsal face. Head smooth and shiny with scattered fine punctulae; pronotum similar, but remainder of mesosoma becoming sublucid, with coriarious-imbricate sculpture; luster of petiole, postpetiole and gaster dulled by moderately dense pubescence. Rather uniformly dark brown, appendages slightly lighter.

Type Material
Ward (2017) - Syntypes, three workers, Sorocaba, São Paulo, Brazil (Göldi) [Examined] [One syntype worker also imaged on AntWeb: CASENT0907543].
