Camponotus thysanopus

Little is known about the biology of . It has been collected two times in the 21st century, more than doubling the known specimens since it was described by Wheeler in 1937.

Distribution based on Regional Taxon Lists
Neotropical Region: Cuba, Greater Antilles.

Castes
Known only from the worker caste.

Nomenclature

 *  thysanopus. Camponotus (Myrmeurynota) thysanopus Wheeler, W.M. 1937b: 461 (w.) CUBA.

Worker
Media and minor. Length 3--4 mm.

Closely related to Camponotus albistramineus of Haiti but smaller. Head trapezoidal, shorter, not longer than broad, less narrowed anteriorly and with distinctly less convex cheeks and posterior border. Eyes more convex, the carinae between their posterior orbits and the corners of the head less pronounced. Antennae slender, scapes extending about two-fifths their length beyond the posterior border. Thorax shaped much as in albistramineu8, but lower, dorsally and laterally less convex and with distinctly more sloping epinotal declivity. Petiolar scale narrower but thicker anteroposteriorly, as thick above as below, with blunter and seen from behind ,less broadly rounded posterior border.

Sculpture like that of albistramineus, but the gaster is shining above as well as below with its dorsal surface sharply transversely shagreened instead of reticulate and with more pronounced transverse piligerous punctures.

Pilosity similar to that of albistramineus but the flattened snow-white hairs are more abundant on the dorsal surface, especially on the head and thorax, and the erect hairs are more obtuse and more flattened, like the appressed hairs, than in the Haitian species. Moreover, the flexor border of each femur bears a more conspicuous fringe of these longer hairs.

Black, with red mandibles and antennae, like, albistramineus, but with the legs also red instead of black; coxae darker and more brownish.

Type Material
Described from three media workers and a minor from the Sierra de Purias (type-locality), north of Imias, 3500 ft., July 25, 1936, and a single media from the Sierra del Cobre, 3000-3500 ft., July 3, 1936.
