Comments:

J. Longino, 30 Mar 2014: I am treating P. inermis as a junior synonym of P. biconstricta. Pheidole inermis is a version of P. biconstricta that lacks any trace of a propodeal spine. There is continuous variation in the size of the propodeal spine in P. biconstricta, and in some cases it is reduced to a minute denticle. DNA barcoding data places three specimens that lack the propodeal spine among P. biconstricta specimens. Thus I assume that P. inermis is just an extreme of variation within P. biconstricta.

Pheidole inermis MayrHNS

Pheidole inermis MayrHNS 1870b: 984. Types Naturhist. Mus. Wien.

Etymology L inermisHNS, unarmed, referring to the absence of propodeal spines.

Diagnosis Distinguished from all other members of the biconstrictaHNS group and most of PheidoleHNS species by the absence of propodeal spines in the major and minor. In full-face view, occipital cleft of major relatively shallow, occipital lobes tending toward subangulate.

Measurements (mm) Lectotype major: HW 1.84, HL 1.72, SL 1.06, EL 0.24, PW 0.84. Paralectotype minor: HW 0.80, HL 0.94, SL 1.10, EL 0.14, PW 0.54.

Color Major: most of body light reddish brown, with mandibles, postpetiole, and gaster medium reddish brown. Minor: gaster medium brown, rest of body light reddish brown.

range I have verified series of inermisHNS from Veracruz, Mexico (Cuichapa, 1600 m); Honduras (Mina El Mochito, Santa Barbara, 1040 m; Lago Yojoa, Cortes, 700 m); and Nicaragua (Matagalpa, 1200+ m).

Biology The species has been collected in montane forest, in one case (Mina El Mochito, Honduras) from rotting wood.

figure Upper: lectotype, major. Lower: paralectotype, minor. MEXICO (no further data; Edward Norton, 1860s). Scale bars = 1 mm.
