Worker: Total body length 4.3 mm; head width 1.7 mm; forewing length 3.5 mm. Head slightly wider than long; inner orbits of compound eyes converging below (Fig. 3); malar area subequal to width of third flagellomere; clypeus about twice as broad as long; interalveolar distance equal to median ocellar diameter, shorter (0.8x) than alveolar diameter; alveolocular distance 1.7 times alveolar diameter, 2.1 times interalveolar distance; interocellar distance about two times median ocellar diameter, 1.2 times longer than ocellocular distance; ocelloccipital distance about 1.3 times median ocellar diameter; scape 3.3 times longer than wide, 1.5 times broader than width of third flagellomere, distinctly convex on outer margin, abruptly narrowed on basal one-fourth; pedicel about as long as broad, slightly shorter than first flagellomere; flagellomeres slightly broader than long, except apical flagellomere much longer than broad (Fig. 4); compound eye 2.7 times longer than broad; gena 0.7 times narrower than compound eye in profile. Scutum with anterior margin rounded, 1.2 times broader than long, about twice as long as scutellum; scutellum 1.4 times broader than long, narrowly rounded on distal margin (long-paraboloidsensuCamargo and Moure 1994); hind tibia 2.6 times longer than broad; hind basitarsus about twice as long as broad, strongly projecting on posterodistal margin.  Integument in general finely and densely punctate, dull, as in other species of the genus; propodeum without impunctate midline.  Color predominantly ferruginous, except: black on upper two-thirds of frons, apex of scape, pedicel, flagellum; dark reddish brown on subantennal area, epistomal sulcus, malar area, mandible distally (darker on teeth), mesepisternum ventrally, hind tibia distally, outer surfaces of middle and hind basitarsi; yellow maculations as follows: mandible basally, labrum, scape, face (Fig. 3), gena and vertex with complete, thin band (at most as wide as median ocellar diameter), pronotum, pronotal lobe, anterior one-third of tegula, costal sclerite, mesepisternum laterally, metepisternum entirely, propodeum laterally, scutum laterally with broad band (as wide as median ocellar diameter), axilla, lateral and distal margins of scutellum with narrower band than on scutum, apices of middle and hind femora, outer surfaces of fore and middle tibiae with narrow band, hind tibia with band on posterior margin, fore and middle basitarsi basally. Wing membrane subhyaline with weak greenish and coppery reflections; veins and stigma dark brown (Figs 1, 2).  Body sparsely covered with minute, appressed, simple yellowish to whitish hairs except as follows: inferior margin of mandible, labrum, and hypostomal area with long (about as long as median ocellar diameter), erect hairs; scape with stiff, erect, simple hairs (0.5 times width of third flagellomere) along inner margin (Fig. 4); gena laterally with few stiff, erect hairs as those on scape; mesepisternum ventrally, middle and hind coxae, sterna with much longer, erect simple hairs (about twice as long as median ocellar diameter); sides of propodeum with dense, branched, semierect hairs (0.5 times median ocellar diameter) partially obscuring integument.  Male: Unknown.  Queen: Unknown.
