Cephalotes klugi

Nothing is known about the biology of .

Identification
A member of the grandinosus clade characterised in the gyne by the yellow-orange gaster with a dark-brown median, transversal stripe. It differs from its sister species grandinosus by the smaller and more superficial body foveolation. Easily differentiated from Cephalotes grandinosus in the gyne by the much smaller, shallower and sparser foveae on the head and mesosoma. (de Andrade and Baroni Urbani 1999)

Queen
de Andrade and Baroni Urbani (1999) - Head disc present. Head dorsum with concave sides and with gently convex frons. Frontal carinae with parallel sides. Posterior border of the disc slightly convex and medially incised by the depression of the vertex. Border of the frontal carinae raised and sparsely crenulate. Vertexal angles obtuse and marginate. Eyes visible in full dorsal view. Ocelli remote from the posterior border of the head disc. Anterior clypeal border concave. Mandibles with a lateral carina and partially hidden by the frontal carinae.

Mesosoma. Anterior pronotal border straight. Humeral angles with a pair of obtuse, membranaceous borders diverging backwards and connected to a weak pronotal crest shortly interrupted in the middle. Pronotal sides posterior to the angles straight. Promesonotal suture impressed. Lower mesopleurae with a stout denticle. Mesonotum and scutellum flat. Propodeum with differentiate basal and declivous faces; sides of the basal face convex, ending in a round tooth posteriorly; sides of the declivous face converging posteriorly.

Anterior face of the petiole concave; petiolar dorsum gently sloping anteriorly; petiolar sides with a narrow, convex, lamellaceous expansion. Postpetiole convex; anterior half of its sides with a pair of obtuse teeth directed laterally and with narrow, membranaceous expansions.

Gaster with a pair of obtuse lobes protruding anteriorly and with the margin not reaching the stigma posteriorly.

Legs. Fore coxae angulate anteriorly. Hind femora gently compressed and carinate dorsally; posterior margin of the ventral face of the mid and hind femora with a narrow, membranaceous crest. Hind basitarsi long and flattened at the base.

Sculpture. Frons covered by small, dense, superficial foveae diminishing in size anteriorly. Sides of the head dorsum superficially punctate and with rare foveae. Frontal carinae transparent. Ventral face of the head reticulate and with minute, sparse, shallow foveae. Pronotum medically with the same type of sculpture as on the sides of the head. Mesonotum and scutellum reticulate and with foveae as broad as on the posterior part of the frons, the foveae diminishing in size on the posterior part of the scutellum. Propleurae, lower mesopleurae, metapleurae and declivous face of the propodeum reticulate; few thin, faint rugulae transversally oriented on the declivous face of the propodeum and longitudinal on the metapleurae and on the lower mesopleurae. Posterior part of the pronotum, upper mesopleurae, basal face of the propodeum and pedicel reticulate and with dense, small foveae as on the frons. Gaster and legs reticulate, with thin, faint, longitudinal rugosities on the anterior third of the first gastral tergite.

Pilosity. Each fovea with an appressed hair. Border of the frontal carinae and of the vertexal angles, mesosoma, pedicel and tergites with sparse, suberect, clubbed hairs; similar hairs but shorter on the sternites and on the legs. Gaster and legs with an additional type of hairs, thin, sparse and appressed. Sternites, distally, with rare, long, thin, slightly pointed hairs.

Colour. Head dorsum, anterior half of the ventral part of the head, pronotum, sides of the pedicel, of the basal face of the propodeum, posterior half of the first tergite, two posterior thirds of the sternites and legs light brown; femora darker; clypeus, posterior half of the ventral part of the head, mesonotum, scutellum, propodeum, pedicel, pleurae, second fourth of the first gastral tergite and anterior third of the first gastral sternite black. Anterior fourth of the first gastral tergite yellow.
