Pheidole pubiventris Mayr View in CoL   HNS

Pheidole pubiventris Mayr   HNS 1887: 595, 604, 607. Syn.: Pheidole pubiventris r. cearensis   HNS Forel 190 lj: 353, n. syn.; Pheidole pubiventris var. nevadensis   HNS Forel 1901J: 353, n. syn.; Pheidole pubiventris r. timmii   HNS Forel 1901m: 62, n. syn. (Types not seen: Pheidole pubiventris   HNS vw. foederalis Borgmeier   HNS 1928a: 34.)

TYPES Naturhist. Mus. Wien; Mus. Comp. Zool. Harvard.

etymology L pubiventris   HNS , hairy belly, evidently alluding to the conspicuously long pilosity of the gaster.

Diagnosis A medium-sized brown member of the diligens   HNS group with relatively sparse, extremely long, erect to suberect curving

hairs over the dorsa of the head and body.

Major: sculpturing of head consists entirely of carinulae, which are confined to the anterior half of the head capsule; promesonotal profile trilobous and pronotal humerus subangulate in dorsal-oblique view. Minor: humerus angulate; pronotum mostly foveolate and opaque.

Similar to longiseta   HNS , sensitiva   HNS , and variegata   HNS ; differing in many details of body form, sculpturing, and pilosity, as illustrated. See also the less similar blumenauensis   HNS , rochai   HNS , seeldrayersi   HNS , and vafra   HNS .

Majors from Colombia have shorter pilosity and more angulate humeri than the Brazilian series; and thus may represent a distinct species.

Measurements (mm) Syntype major (Mus. Comp. Zool. Harvard): HW 1.14, HL 1.12, SL 0.86, EL 0.22, PW 0.56.

Syntype minor (Mus. Comp. Zool. Harvard): HW 0.54, HL 0.68, SL 0.86, EL 0.16, PW 0.40.

Color Major: light reddish yellow (probably a callow or faded; fresher specimens are blackish brown).

Minor: body medium brown, with light brown appendages (fresher specimens are blackish brown).

Range Santa Catarina, Sao Paulo, and Ceara, Brazil; and Magdalena, Colombia.

biology The localities, combined with a note accompanying a specimen from El Campano, Magdalena, Colombia ("in road," W. L. Brown), suggests that this species may be adapted to disturbed habitats. A winged queen was collected at El Campano in June.
