Holotype redescription
MEASUREMENTS. Length: 9.2 mm. Width: 3.8 mm.
HEAD. Reddish-brown, surface with upright setae. Labroclypeus, shape of anterior margin convex, posteriorly with dense punctation. Ocular canthus with terminal setae, ratio to eye: 1/2. Ratio third vs fourth antennomere: 1/3. Fourth antennomere, lateral projection absent. Ratio fifth vs fourth antennomere: 1/5.
