Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • avia. Pheidole guilelmimuelleri subsp. avia Forel, 1908c: 380 (w.) BRAZIL. Forel, 1911c: 303 (s.). Raised to species: Wilson, 2003: 659.

Description

From Wilson (2003): DIAGNOSIS Similar to Pheidole antillana of the Lesser Antilles and to Pheidole bucculenta, Pheidole guilelmimuelleri and Pheidole hetschkoi of South America, as well as to Pheidole mamore of South America in the scrobifera group, but differing in the following combination of traits.

Major: very large, with sharp postpetiolar cornicles, otherwise close to the lectotype major of guilelmimuelleri (q.v.); but the minor is very distinct.

Minor: occiput and anterior fourth of head bears transverse carinulae; carinulae originating on the frontal lobes curve outward (laterad) to join the anteriormost transverse posterior carinulae; anterior half of the pronotal dorsum transversely carinulate; rest of the head and body almost entirely smooth and shiny; propodeal spines moderately long, thin, and vertical.

MEASUREMENTS (mm) Paralectotype major: HW 2.34, HL 2.40, SL 1.04, EL 0.24, PW 1.12. Lectotype minor: HW 1.00, HL 1.14, SL 2.04, EL 0.24, PW 0.68.

COLOR Major: reddish yellow.

Minor: concolorous plain yellow.
