Holotype redescription

MEASUREMENTS. Length: 12 mm. Width: 5.8 mm.

HEAD. Reddish-brown, surface with setae. Labroclypeus, shape of anterior margin convex. Ratio ocular canthus/eye: 1/4. Antennae with eight antennomeres; antennal club with three antennomeres; ratio antennal club/remaining antennomeres: 1/1; ratio third vs fourth antennomere: 1/4; fourth antennomere, lateral projection absent; ratio fifth vs fourth antennomere: 1/5.

PRONOTUM AND ELYTRA. Surface of pronotum and elytra without setae. Pronotum unicolored, reddishbrown, widest at base, anterior marginal line present, posterior marginal line absent, lateral margin weakly convex and not serrated, antero-lateral angle dorso-ventrally flattened, postero-lateral angle dorso-ventrally flattened, median longitudinal excavation absent. Scutellum, punctures absent medially. Elytra bicolored, surface opaque, microsculpture absent, punctation on intervals present and sparse, diameter of strial and interval punctation equal.

ABDOMEN. Lateral carina present. Apical visible ventrite without suture to apical tergite.

LEGS. Metacoxa without longer lateral bristles, a laterally extended longitudinal shelf present. Metatibia, widest at apex, distal spines groups disposed at two thirds of metatibial length. First metatarsomere, ratio to dorsal metatibial spur 1/3. Metatarsi, length of first protarsomere smaller than second and third combined, ventral margin serrated and setose. Protibia with three teeth. Protarsi, length of first protarsomere subequal to second and third combined, second protarsomere narrow, claws symmetrical, inner protarsal claw bifid, apex of basal tooth of inner protarsal claw acute.
