Description.

(Holotype) Body length 6 mm. Head yellowish brown, higher than long. Eye small, rounded oval and vertically elongated.

Frons projecting before eye margin at a distance corresponding to the length of eye, with triangular fore margin and long black frontal setae. Ocellar triangle posteriorly as broad as half width of frons, narrowing to middle and reaching front of frons as a narrow point, brown, with gray microtrichosity and with dark brown longitudinal median groove (Fig. 5). Ocellar tubercle black. Interfrontal setae in two rows on margin of ocellar triangle, long, irregularly incurved. Ocellar setae long and slender, similar to other relatively long setulae on head. External and internal vertical setae indistinct, numerous orbital setae. Clypeus large, brown to black, slightly gray microtrichose. Proboscis short, palpus short, but clubbed, yellow, with numerous long black setulae. Antenna yellow, pedicel large, about as long as broad, 1st flagellomere longer than broad.

Female with long cerci (Fig. 12).
