Pheidole littoralis Cole View in CoL HNS
Pheidole sitarches littoralis Cole HNS 1952b: 443. Raised to species level by Naves 1985: 64.
Types Amer. Mus. Nat. Hist.; Nat. Mus. Nat. Hist. U.S.; Mus. Comp. Zool. Harvard.
Etymology L littoralis HNS , of the shore, referring to the habitat at the type locality.
diagnosis A member of the " pilifera HNS complex" of the larger pilifera HNS group, comprising calens HNS , californica HNS , carrolli HNS , cavigenis HNS , clementensis HNS , creightoni HNS , hoplitica HNS , littoralis HNS , micula HNS , pilifera HNS , polymorpha HNS , rugulosa HNS , senex HNS , soritis HNS , tepicana HNS , torosa HNS , which complex is characterized by the following traits. Major: dorsal head surface extensively sculptured; occipital lobes horizontally rugulose (or, in carrolli HNS smooth, in littoralis HNS foveate, and in micula HNS and soritis HNS carinulate; postpetiole from above diamond-shaped, trapezoidal, or spinose. Minor: eye medium-sized to large.
P. littoralis HNS is easily distinguished within the complex by the following combination of traits.
Major: occiput not rugulose, but covered with conspicuous foveae; anterior and lateral margins of pronotum rugoreticulate; mesonotum longitudinally carinulate; triangular subpostpetiolar process present; postpetiole from above diamond-shaped.
Minor: most of head, mesosoma, and waist foveolate and opaque.
Measurements (mm) Paratype major: HW 1.40, HL 1.52, SL 0.56, EL 0.20, PW 0.58.
Paratype minor: HW 0.58, HL 0.50, SL 0.42, EL 0.12, PW 0.28.
color Major: gaster plain medium to dark brown; remainder of body, and appendages, reddish brown. Minor: most of body light brown, with dark brown gaster and brownish yellow appendages.
Range Apparently limited to central Florida.
biology Naves (1985) and Stefan Cover (unpublished) found littoralis HNS very common nesting in white-sand scrub at the Archbold Field Station near Lake Placid, Florida, and close to colonies of adrianoi HNS and metallescens HNS . The excavations are relatively very deep, beneath crescentic crater mounds, and the colonies small. A granary chamber filled with seeds is always found 10 to 20 cm beneath the surface.
