Description. Head broadly triangular, with rounded sides, narrowed anteriorly, vertex and sides slightly convex. Mandibles triangular, with 5 teeth on the masticatory border, the apical and subapical larger than the others. Antenna with 9 segments. Scape clearly fails to reach the vertexal margin. Eyes well developed, situated near anterior margin of the head, with about 8 ommatidia in their maximum diameter. In dorsal view, promesonotum trapezoidal, sides and dorsum well defined. Promesonotum strongly convex in lateral view. Promesonotal suture well defined dorsally and laterally. Propodeum unarmed. Propodeal spiracles conspicuous, situated on the edge of declivitous face of propodeum, their aperture obliquely directed backward and upward. Metapleural gland bullae conspicuous, bigger than propodeal spiracle. Propodeal lobes small, rounded. Petiole in profile with short anterior peduncle, followed by a high and narrow node, its apex narrowly pointed. Petiolar peduncle attains petiolar mid length. Petiolar spiracle at base of node. Subpetiolar process present, as a keel-like lamella that ends in rounded apex anteriorly. Postpetiole low, rounded in frontal view, noticeably wider than long in dorsal view. Gaster without humeral angles basally. Head, promesonotum, petiole, postpetiole, gaster, scapes and legs smooth and shining. Lower side of mesopleuron and petiolar peduncle finely reticulated; propodeum with fine reticulation on the declivous face, between the propodeal spiracles and on the metasternal lobes. Body devoid of standing pilosity, except for very short, sparse minute hairs on head, legs and scape. Reclined minute hairs on thorax and gaster. Pilosity denser and longer on antennae. Row of hairs on the anterior clypeal margin, including median hair (not visible in the Automontage Picture). Central clypeal hair accompanied by two lateral hairs, although both lateral hairs not in the same plane (in full face view the 3 hairs appearing as the same length). Body yellow, eyes and mandibular teeth dark. Pilosity golden.
