Pheidole carrolliHNS Naves

Pheidole carrolliHNS Naves 1985: 58.

types Florida State Collection of Arthropods; Mus. Comp. Zool. Harvard.

Etymology Named after James F. Carroll, collector of part of the type series.

diagnosis A member of the " piliferaHNS complex" of the larger piliferaHNS group; for a characterization of the complex, see under piliferaHNS. Very close to piliferaHNS itself (q.v.), and differing as follows. The only consistent distinction is the orange color of carrolliHNS versus the browns, yellowish browns, and reddish browns of the highly variable, more northern distributed piliferaHNS. In addition the major of carrolliHNS has occiput and dorsal surface of postpetiole completely smooth, but this trait also occurs in some piliferaHNS series.

Measurements (mm) Holotype major: HW 0.56, HL 1.82, SL 0.70, EL 0.24, PW 0.68.

Paratype minor: HW 0.52, HL 0.58, SL 0.54, EL 0.14, PW 0.32.

Color Major: "orange," i.e., concolorous brownish yellow with a slight reddish tinge.

Minor: concolorous yellowish brown, head a slightly darker shade of light brown.

Range Known from Alachua, Citrus, and Leon Counties in northern Florida.

Biology Naves (1985) found carrolliHNS only in the shaded, sandy soil of tall oak or pine woodland. Subsequent collection by Stefan Cover and Lloyd Davis Jr. have securely identified carrolliHNS as an early successional species that occurs in open, often disturbed habitats with sandy soil. Colonies are vigorous and consist of several hundred ants, including several dozen soldiers. Naves' collections may represent moribund colonies in poor nest sites, or colonies about to be eliminated by shading of formerly open habitats. The colonies are small, with only one or two majors present. According to Naves, no more than 15 minors forage at a time, and then singly and mostly at dusk and in the morning, for distances not exceeding 5 meters from the nest entrance. The entrance is difficult to spot and leads to exceptionally deep vertical galleries, in one case extending 1.7 m from the surface. A seedfilled granary chamber approximately 4 X 2 X 2 cm in size is present usually at a depth of 30 cm. The minor workers are exceptionally sluggish, and show the unusual, perhaps unique habit for PheidoleHNS of feigning death when disturbed, often curling themselves around particles of soil in a way that makes them even more difficult to see.
