Description
From Wilson (2003): DIAGNOSIS A member of the tachigaliae group, characterized by very small size and 11-segmented antennae, this species is easily recognized by the following traits.
Major: dorsal surface of head longitudinally carinulate (not transversely carinulate as in other tachigaliae-group species); pronotal dorsum lightly sprinkled with foveolae, feebly shiny; propodeal spines short, stout and directed strongly backward.
Minor: all of head and mesosoma foveolate and opaque.
MEASUREMENTS (mm) Lectotype major: HW 0.64, HL 0.74, SL 0.32, EL 0.08, PW 0.40. Paralectotype minor: HW 0.34, HL 0.38, SL 0.28, EL 0.08, PW 0.22.
COLOR Major: concolorous medium yellow; vertex with a fuzzy, circular brown spot as illustrated.
Minor: concolorous pale yellow.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
