Name
Pheidole allarmata Wilson, E. O., 2003 – Wikispecies link – Pensoft Profile
- Pheidole allarmata Wilson, E. O., 2003: 649-649.
Etymology
etymology Gr, L allarmataHNS, the "other one" bearing arms, referring to the species' similarity to subarmataHNS and synarmataHNS. diagnosis Similar to hasticepsHNS, subarmataHNS, synarmataHNS, and triplexHNS (see also the somewhat less similar rhytiferaHNS), differing from these and other PheidoleHNS by the following combination of traits.
Diagnosis
Major: in side view the frontal lobe is elongated to form a forward-projecting, thin, spine-like lobe; humerus strongly developed as protuberant lobes; postpetiolar node spinose; head quadrate; rear half of head and almost all of body smooth and shiny. Minor: occiput narrowed but lacking a nuchal collar; propodeal spine long, thin, and erect; head and body almost entirely smooth and shiny.
Description
This is probably the series noted by W. L. Brown (1981: 526) as representing a species distinct from subarmataHNS. measurements (mm) Holotype major: HW 1.26, HL 1.28, SL 0.60, EL 0.12, PW 0.74. Paratype minor: HW 0.56, HL 0.56, SL 0.60, EL 0.06, PW 0.36. Color Major: head reddish brown, gradually deepening from light reddish brown at occiput to dark reddish brown on anterior half of head capsule and on mandibles; mesosoma medium reddish brown; waist, gaster, antennae, and legs light reddish brown. Minor: concolorous yellow to dark brown.
Distribution
Range An Amazonian species recorded from scattered localities in Brazil, Colombia, Ecuador, Peru, and Suriname.
Biology and Ecology
Biology Two colonies collected by Stefan Cover and John E. Tobin at Cuzco Amazonico, Peru (Cover, collection notes) were in terra firme rainforest, nesting in rotten sticks on the forest floor. The colonies were small, with fewer than 100 workers and a single queen; one of the nests contained a seed cache.
