Pheidole chloe HNS Forel, new status
Pheidole goeldii subsp. chloe HNS Forel 1908c: 56.
Types Mus. Hist. Nat. Geneve; Mus. Comp. Zool. Harvard.
Etymology Gr chloe HNS, first green shoots of plants in spring, allusion unknown.
diagnosis A member of the flavens HNS group close to striaticeps HNS 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).
Range Costa Rica and Mexico. Longino (1997) does not distinguish this species from striaticeps HNS, although the two appear to be different. He reports " striaticeps HNS, " which may include both species, from the Atlantic slope to 500 m and Pacific lowlands of Costa Rica.
Biology Longino (1997) reports " striaticeps HNS," which as noted, may include both true striaticeps HNS and chloe HNS, from mature rainforest, nesting beneath the bark of rotten stumps and logs.
