Nomenclature

 *  goeldii. Cryptocerus goeldii Forel, 1912e: 205 (w.) BRAZIL. De Andrade & Baroni Urbani, 1999: 724 (s.q.m.). Combination in Paracryptocerus (Harnedia): Kempf, 1958a: 93; in Zacryptocerus: Brandão, 1991: 386; in Cephalotes: De Andrade & Baroni Urbani, 1999: 722.

Worker
Kempf (1967) - Total length 4.6 mm; maximum head length 1.36 mm; maximum width of head above eyes (the latter excluded) 1.39 mm; thorax length 1.39 mm; petiole width 0.58 mm; postpetiole width 0.64 mm; gaster width 1.49 mm.

The worker of this species shares with Cephalotes angustus and Cephalotes pallidicephalus the unique feature (in the angustus group!) of having the gaster laterally sharply marginate well beyond the anterior half, the trans lucid anterolateral lamella extending backwards much beyond the distinctly visible dorsal stigma.

The differences from angustus are as follows: Tip of scape, tibiae and tarsi rather yellowish brown than ferruginous; gastral markings more extensive, a broad and well circumscribed band just lies inside the lateral border. Occipital lobes subhyaline, yellowish, conspicuous. Dentition of thoracic border somewhat different, principally on epinotum, where there are four distinct teeth. Promesonotal suture quite distinct (usually obsolete, sometimes vestigial in angustus). Lateral spines of pedicellar segments not needle-like but broader and flattened; those of postpetiole distinctly recurved. Petiole without antero-dorsal denticles; postpetiole dorsally completely flat. Gaster short, subcircular, with the anterolateral hyaline border broader than in angustus.

The differences from pallidicephalus are as follows: color, occipital lobes and anterolateral border of gaster as stated under angustus. Sternum I of gaster without coarse costae or rugae but smooth.

Soldier
de Andrade and Baroni Urbani (1999) - Head very large, with a complete, round disc. Border of the disc strongly raised and lamellaceous. Vertexal angles with an obtuse, broad lamella continuing up to the eyes. Vertexal border concave and without margin. Mandibles with a strong carina. Dorsal border of the antennal scrobes with a short, denticulate carinae just in front of the eyes. Eyes convex and partially hidden by the head disc.

Mesosoma. Anterior pronotal border gently convex. Pronotal sides with a pair of very broad expansions, anteriorly obtuse, medially truncate, posteriorly converging. Border of the pronotal expansions lamellaceous. Pronotal carina lamellaceous, strongly developed, narrowing from the sides to the center where it is interrupted by a superficial sulcus. Promesonotal suture impressed. Mesonotum with a broad, round tooth with lamellaceous border. Propodeal suture deeply impressed. Propodeum with well differentiate basal and declivous faces. Sides of the basal face with a small swelling followed by two pairs of teeth; first pair of propodeal teeth short, broad and rounded, the second pair broad, thick, curved upwards and forwards at the apex and obtuse. Declivous face concave in the middle; its sides converging and bearing a pair of short, lamellaceous teeth.

Petiole with differentiate anterior and posterior faces; anterior face truncate, posterior face sloping backwards. Sides of the petiole, medially, with a thick, round tooth directed backwards. Postpetiole convex. Postpetiolar sides with a pair of thick, round expansions arising from the anterior border and directed anterolaterally.

Gaster oval and with a pair of protruding, anterolateral lamellae reaching the stigma.

Mid and hind femora without angles or denticles. Hind basitarsi slightly more compressed apically than distally and with slightly broad base.

Sculpture. Head dorsum superficially punctate and covered by dense, shallow foveae more superficial and smaller on the anterior third. Ventral part of the head strongly punctate, with longitudinal, slightly irregular rugosities, thinner, more superficial and superimposed to irregular, shallow foveae on the anterior half. Sides of the head and mesosoma with the same type of sculpture as the head dorsum but with foveae more irregular and smaller on the basal face of the propodeum. Propleurae with the same type of sculpture as on the posterior half of the ventral part of head. Lower meso- and metapleurae and pedicel reticulate and with small, irregular foveae. Upper meso- and metapleurae, declivous face of the propodeum, gaster and legs reticulate. First gastral tergite with irregular, small, superficial, oval foveae on the anterior third only; two posterior thirds of the tergite and anterior third and sides of the sternite with thin, superficial, irregular rugulosities. Outer face of the femora and of the tibiae with superficial, oval foveae. Center of the posterior half of the first gastral sternite shining.

Pilosity. Each fovea of the head dorsum with a canaliculate-subclavate, suberect to decumbent hair; other body foveae with appressed, canaliculate hairs. Parts of the legs and of the gaster without foveae with the same appressed hairs as on the mesosoma, but thinner. Sides of the head disc, legs and posterior border of the tergites and sternites with suberect, sparse, clubbed hairs. Sternites with rare, long, pointed hairs.

Colour. Ventral part of the head, center of the mesosoma, pedicel and three ventral fourths of the pleurae brown; sides and dorsum of the head, sides of the mesonotum, last dorsal fourth of the pleurae, sides of the pedicel, yellow-orange. Legs and gaster dark orange-brown with lighter outer face of the tibiae and with a pair of long, yellowish strips on the sides of the first gastral tergite.
