Pheidole guilelmimuelleri subsp. mamoreHNS Mann 1916: 429.

Types Mus. Comp. Zool. Harvard.

Etymology Named after the type locality.

diagnosis Distinguished among members of the scrobiferaHNS group (as well as the somewhat similar antillanaHNS, aviaHNS, bucculentaHNS, guilelmimuelleriHNS, hetschkoiHNS, heyeriHNS, hortonaeHNS, praesesHNS, and rhytiferaHNS in the tristisHNS group) as follows.

Major: rugoreticulum on head limited to a patch posterior to each eye and another inside the anterior part of each antennal scrobe; anterior strip of pronotal dorsum transversely carinulate, the remainder rugoreticulate; mesonotal convexity subangulate in side view. Minor: propodeal spines reduced to denticles; entire body smooth and shining, with the sole sculpturing being the circular carinulae around the antennal fossae.

Measurements (mm) Lectotype major: HW 1.64, HL 1.64, SL 0.74, EL 0.20, PW 0.90. Paralectotype minor: HW 0.60, HL 0.64, SL 0.68, EL 0.14, PW 0.38. color Major: medium to dark reddish brown, appendages light reddish brown. Minor: body plain medium ("chocolate") brown, appendages medium brownish yellow.

Range In addition to the types, I have seen material from around Manaus, Amazonas, Brazil; near Puerto Maldonado, Leticia, and Tingo Maria, Peru; Suriname; and Guyana.

Biology Stefan Cover and John E. Tobin found this species on the floor of forest transitional from terra firme to floodplain at Cuzco Amazonico, near Puerto Maldonado, Peru. I encountered it in primary rainforest near Manaus. Colonies nest in pieces of rotten wood on the forest floor.
