Pheidole punctatissima View in CoL HNS Mayr
Pheidole punctatissima HNS Mayr 1870a: 400. Syn.: Pheidole punctatissima subsp. napaea Wheeler HNS 1934g: 165, synonomy by Brown 1981: 525.
Types Mus. Comp. Zool. Harvard.
Etymology L punctatissima HNS , very dotted with punctures, probably referring to the nearly complete foveolate sculpturing of the body.
diagnosis One of the most instantly recognizable of all Pheidole HNS species: the major has a yellowish white posterior two-thirds of the head capsule (fading to pale yellow in older specimens) that contrasts sharply with the medium to dark brown remainder of the body; the major also is distinguished within the punctatissima HNS group by the large area of rugoreticulation mesad to the eyes (see also inca HNS ) and the very prominent cornulate pronotal humerus and entire surface of the body foveolate and opaque. Minor: no carinulae on entire body, but all of the body parts except the second and succeeding segments of the gaster are foveolate and opaque.
Measurements (mm) Major (Pueblo Nuevo, Mexico): HW 0.92, HL 0.92, SL 0.54, EL 0.14, PW 0.44. Minor (Pueblo Nuevo, Mexico): HW 0.44, HL 0.54, SL 0.50, EL 0.10, PW 0.24.
Color Major: bicolorous, with posterior two-thirds of head surface, together with the lateral wings of the clypeus, yellowish white (fading to pale yellow in old specimens) and all the remainder of the body a sharply contrasting medium to dark brown; the first gastral tergite has bluish reflections; and the appendages exclusive of the mandibles are yellow. Minor: body concolorous medium brown, appendages except for mandibles brownish yellow.
Range Tropical southern Mexico to Colombia. Literature records of the species from the West Indies are in error; they are based on the related species P. bilimeki HNS (= annectens HNS ), q.v.
biology J. T. Longino (1997) on punctatissima HNS in Costa Rica: "This species thrives in disturbed areas, and it is often a pest ant. Nests are often in ephemeral cavities; soft rotten sticks, beneath bark flaps, in debris in forks of trees, etc." In Mexico winged reproductives have been found in nests during April and July.
