. Body integument minutely asperous, mostly glabrous except sparse stiff setae on anterior head margin and gaster. Head only slightly longer than wide. Compound eye oval, moderately large and feebly convex, its outer margin barely surpassing the outline of sides in full-face view, with 38–40 ommatidia. Ocelli absent. Frontal carinae well distant, closer to inner margin of eyes than to each other, not surpassing posterior margin of eyes and without frontal lobe, such that antennal sockets entirely exposed although directed laterad. Antenna 12-merous, scape surpassing vertexal margin by more than one-third its length; first and terminal funicular antennomeres subequal in length, nearly twice as long as broad; all other antennomeres cylindrical, only slightly longer than broad. Vertex with an erect seta (likely paired, but upper left side of head altered) longitudinally aligned with frontal carina, in profile situated at midlength between posterior margins of eye and head. Anterior clypeal margin bordered by seven stiff, short setae inclined ventrally; posterior clypeal margin semicircular, even with posterior level of toruli. Mesosoma: in profile, mesonotal dorsal outline feebly convex in its anterior third, flat and sloped in its posterior two thirds. Mesonotum and propodeum forming a distinct angle at metanotal groove. Metathoracic spiracles raised into distinct tubercules, conspicuously breaking outline of mesosoma in lateral view, distinctly anterior to metanotal groove. Dorsal surface of propodeum flat, declivitous surface convex. In profile, propodeal spiracle at junction of lateral and declivitous surfaces, slightly above midheight of sclerite. Dorsal surface of mesosoma apparently without erect setae. Legs: mesotibia and metatibia each with one spur, that of metatibia pectinate. Metasoma: petiole more than twice as long as wide, nearly as wide as high, broadest around its midlength; ventral and dorsal surfaces feebly convex; ventral surface without lobe, with two anterior longitudinal rows of three short setae. Gaster: abdominal tergite III largest, ventral surface of its anterior projection with a groove that accommodates entire petiole. Tergites III–VI with posterior margin bordered by a row of short appressed setae barely surpassing margin. Tergite VII in dorsal view small, trapezoidal.

The new species is readily recognizable by its anterior clypeal margin with a deep V-shaped incision and broadly rounded lateral margins, the almost complete lack of erect setae on the dorsum of head, mesosoma and first gastral tergite (with the exception of a single pair of setae posterior to the frontal carinae), and the propodeal dorsum that is as long as, or even slightly longer than, the declivitous surface.
