Holotype redescription
MEASUREMENTS. Length: 8 mm. Width: 4 mm.
HEAD. Reddish-brown. Labroclypeus, shape of anterior margin weakly sinuated medially, posteriorly with sparse punctation. Ocular canthus with terminal setae, ratio to eye: 1/3. Antennae with eight antennomeres; antennal club with three antennomeres; ratio antennal club/remaining antennomeres: 1/1; ratio third vs fourth antennomere: 1/3; fourth antennomere, lateral projection absent; ratio fifth vs fourth antennomere: 1/5.
