Diagnosis.

Fore wing weakly melanic distally with a basal transverse melanic band posterad parastigma. Scape half melanic (laterally) and half yellow (medially).

Holotype female.

Body length. 6.12 mm

Head. OOL 0.13; POD 0.15; IOL 0.09; EH 0.88; MS 0.16; 38 (38-40) flagellomeres.

Mesosoma. Mesoscutum punctate; notauli well impressed and crenulate; scutellum with apical carina and subapical transverse depression; sternaulus well impressed and crenulate, extending about ¾ length of mesopleuron; metapleuron rugose in ventral 1/3, punctate dorsally; fore tibial spur as long as basitarsus.

Metasoma. Median tergite 1 about twice as long as wide apically (length = 0.94mm, width = 0.48mm).
