Specimen Labels

Longino (1997). ) reports striaticeps which as noted, may include both true striaticeps and chloe, from mature rainforest, nesting beneath the bark of rotten stumps and logs. (Wilson 2003)


See the description in the nomenclature section.

Keys including this Species


Costa Rica and Mexico. Longino (1997) does not distinguish this species from striaticeps, although the two appear to be different. He reports triaticeps, which may include both species, from the Atlantic slope to 500 m and Pacific lowlands of Costa Rica. (Wilson 2003)

  • chloe. Pheidole goeldii subsp. chloe Forel, 1908b: 56 (s.w.) COSTA RICA. Raised to species: Wilson, 2003: 399.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


From Wilson (2003): A member of the flavens group close to Pheidole striaticeps of Mexico and Central America (and a possible synonym of it), much less so to the other species listed in the heading, and distinguished as follows.

Major: antennal scrobes present; entire dorsal surface of head, except for frontal triangle, covered by longitudinal carinulae, which do not curve inwardly toward midline at occiput; humerus subangulate in dorsal-oblique view; mesonotal convexity absent in both side and dorsal-oblique views; head wider than long (HW/HL 1.04); pronotum lacks transverse carinulae.

Minor: longitudinal carinulae stretch from mesopleuron to sides of propodeum.

MEASUREMENTS (mm) Syntype major: HW 1.00, HL 0.96, SL 0.56, EL 0.14, PW 0.50. Syntype minor: PW 0.36 (head missing in syntype available).

COLOR Major: concolorous light reddish brown.

Minor: body brownish yellow (color of head unknown).
