Pheidole triplex   HNS new species

Types Mus. Comp. Zool. Harvard.

Etymology L triplex   HNS , three parts, referring to the tricolorous condition of the major.

Diagnosis Major: virtually identical with subarmata major   HNS except for its much smaller size (HW about 0.8 mm versus more than 0.9 mm in subarmata   HNS ) and strikingly different color (see below). Stefan Cover, who has examined this species and subarmata   HNS in detail, reports that the head of the triplex major   HNS is also slightly narrower.

Minor: virtually identical with subarmata   HNS minor except for its strikingly different color (see below). Another possible difference is habitat: the triplex   HNS types were collected in mature mountain rainforest, while subarmata   HNS prefers open, even disturbed habitats. Measurements (mm) Holotype major: HW 0.80, HL 1.06, SL 0.44, EL 0.12, PW 0.46. Paratype minor: HW 0.42, HL 0.46, SL 0.42, EL 0.09, PW 0.28.

Color Major: strongly tricolorous, with head and mandibles uniformly medium brown; mesosoma, waist, and appendages yellow;

and gaster light brown.

Minor: concolorous clear light yellow.

Range Known only from the type locality.

Biology The type colony was found in mature montane rainforest, nesting beneath a rock in clay soil. A seed cache was present.

Type locality TRINIDAD: Aripo Ridge, Arima Valley, 550-650 m (Stefan Cover and Mark W. Moffett). [Not figured]
