Pheidole schmalzi EmeryHNS, new status

Pheidole dimidiata var. schmalzi EmeryHNS 1894d: 161. Syn.: Pheidole rehiHNS Forel 1900h: 285, n. syn. Pheidole rataHNS Borgmeier 1929: 206, n. syn.

Types Lectotype and paralectotype of schmalziHNS: Mus. Civ. Hist. Nat. Genova.

Etymology Named after the collector "Signor Schmalz."

diagnosis A medium-sized reddish yellow to brown member of the flavensHNS group; both major and minor are immediately recognizable by the large, "sharkfin" shape of the humerus in dorsal-oblique view, meaning that the anterior margin is straight and the posterior margin convex in profile, tipped with an acute or right angle. Very similar to anguliferaHNS, and in varying degree also to arhuacaHNS, caulicolaHNS, chalcaHNS, chalcoidesHNS, mincanaHNS, saganaHNS, tambopataeHNS, and tragicaHNS in overall appearance but distinctive in the humeral shape and other traits in body shape, sculpture, pilosity, and color.

Measurements (mm) Lectotype major: HW 0.94, HL 0.94, SL 0.46, EL 0.10, PW 0.48. Paralectotype minor: HW 0.50, HL 0.54, SL 0.58, EL 0.08, PW 0.34.

color Lectotype major of schmalziHNS: body and appendages light brown, waist and gaster dark brown ( rehiHNS syntype major is yellowish brown; rataHNS syntype major is light reddish yellow).

Paralectotype minors of schmalziHNS: body light to medium brown, appendages light brown.

Syntype minors of synonymous rehiHNS and rataHNS: light brown.

Range Santa Catarina and Rio de Janeiro, Brazil; Bolivia; Venezuela.

Biology Unknown.
