Diagnosis.
Minor
: face uniformly foveolate; promesonotal groove distinct, impressed; entire mesosoma foveolate, pronotal dorsum overlain to variable extent with reticulate rugulae; propodeal spines about one third length of posterior face of propodeum; gaster smooth and shining; dorsal mesosoma, gaster, and tibiae with abundant, flexuous, erect setae; color yellow.
Major
: inner hypostomal teeth widely spaced, acicular; scape base terete; face with foveolation and carinulae between eyes and frontal carinae, completely smooth and shining elsewhere; propodeal spines about one fourth length of posterior face of propodeum; first gastral tergite smooth and shiny; head, mesosoma, gaster, and tibiae covered with long, somewhat silky, subdecumbent setae.

Biology.
This species occurs in montane wet forest. All collections have been from about
1000-1600 m
. Foragers are epigaeic, diurnal or nocturnal, and can be locally abundant at baits. Workers also occur in Winkler samples. One nest was encountered in bare soil of a recent landslide. Workers at a bait led to a simple crack in the soil, with no obvious nest entrance. The main nest chamber with abundant workers and brood was about
15 cm
deep.
Comments
.
Pheidole luteagossamer
is an interesting combination of other species. The minor workers are indistinguishable from
P. acamata
, and the majors are very similar to
P. biolleyi
from
Costa Rica
. Majors of
P. biolleyi
have the dorsal mesosoma glassier, with less sculpture.
Etymology
: In reference to the yellow color and the woolly pilosity of the major worker.
