Small size (HW 0.72-0.88, WL 0.79-0.91). Masticatory margin of mandibles with four teeth; head shape quadrate, as long, or slightly longer than wide (CI 1.02-1.11); posterior margin of head in full-face view laterally rounded; occipital carinae distinct; antennal scapes reaching or slightly surpassing head margin; midline of eyes situated slightly above midline of head in full-face view; eyes moderately large (OI 0.20-0.25) and protruding. Pronotum laterally angular; promesonotal suture indistinct, promesonotum forming one plane; mesonotum usually without posterior face; laterally mesonotum carinate, sometimes ending in small denticles, but not greatly set off from propodeum; metanotal groove shallow, laterally constricted and bordered by carinae; propodeal spines short, spiniform (SPI 0.06-0.10) and straight; dorsal face of propodeum distinct; posterior face of propodeum gently sloping; petiole in dorsal view greatly flared and convex, dorsolaterally rounded to carinate, without posterolateral tubercules or denticles; subpetiolar process usually a small, angular dent; postpetiole distinctly bilobed, with a narrow median impression; subpostpetiolar process absent. Head sculpture aciculate to faintly reticulate; sculpture otherwise mostly reticulate; face usually with < six erect, longer setae, and regular appressed to decumbent pubescence; erect pilosity on promesonotum usually sparse, < six long setae; otherwise promesonotum dorsally with sparse appressed to subdecumbent pubescence; petiole and postpetiole usually with a pair of short, erect setae posterolaterally, and sparse suberect, decumbent or appressed pubescence; abdominal tergites and sternites four to seven usually with moderately abundant, short, erect pilosity, and regular appressed to decumbent pubescence throughout. Color yellow-brown to brown.

Queen
(n = 1) HW 1.01, HL 1.01, EL 0.33, SL 0.64, MSNW 0.76, MSNL 0.87, WL 1.68, SPL 0.00, PTH 0.29, PTL 0.33, PTW 0.39, PPL 0.23, PPW 0.39, LHT 0.75, CI 0.99, OI 0.32, SI 0.63, MSNI 0.87, SPI 0.00, PTHI 0.87, PTWI 1.18, PPI 1.68, LBI 2.24. Small queen (HW 1.01, WL 1.68). With worker characters, except as follows. Masticatory margin of mandibles with five teeth; antennal scapes reaching level of lateral ocelli; eyes large (OI 0.33), situated below midline of head in full-face view; head elongate-rectangular (CI 0.99), posterior margin straight. Mesoscutum in dorsal view longer than wide (MSNI 0.87); dorsal face of propodeum short; propodeal tubercules or denticles absent; petiole moderately flared, postpetiole with complete impression; subpetiolar process present as minute tooth.

Sculpture aciculate to reticulate throughout; face with six longer erect setae (but n = 1) and regular short suberect to decumbent pubescence; mesonotum with regular short, erect to suberect pubescence, interspersed with abundant, longer, erect setae; petiole and postpetiole with fairly dense, short, suberect to decumbent pilosity, and postpetiole with additional longer dorso-posterior setae; abdominal tergites and sternites four to seven with abundant, short, erect pilosity and dense appressed to decumbent pubescence. Color yellowish brown.
