diagnosis A member of the " piliferaHNS complex" of the larger piliferaHNS group, comprising calensHNS, californicaHNS, carrolliHNS, cavigenisHNS, clementensisHNS, creightoniHNS, hopliticaHNS, littoralisHNS, miculaHNS, piliferaHNS, polymorphaHNS, rugulosaHNS, senexHNS, soritisHNS, tepicanaHNS, torosaHNS, which complex is characterized by the following traits. Major: dorsal head surface extensively sculptured; occipital lobes horizontally rugulose (or, in carrolliHNS smooth, in littoralisHNS foveate, and in miculaHNS and soritisHNS carinulate; postpetiole from above diamond-shaped, trapezoidal, or spinose. Minor: eye medium-sized to large.
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biology Naves (1985) and Stefan Cover (unpublished) found littoralisHNS very common nesting in white-sand scrub at the Archbold Field Station near Lake Placid, Florida, and close to colonies of adrianoiHNS and metallescensHNS. 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.
