Holotype redescription
MEASUREMENTS. Length: 11 mm. Width: 5.6 mm.
HEAD. Reddish-brown, surface with upright setae. Labroclypeus, shape of anterior margin straight, posteriorly with dense punctation. Ocular canthus with terminal setae, ratio to eye: 1/3. Eyes, ratio diameter/interocular width: 0.56. 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.
PRONOTUM AND ELYTRA. Surface of pronotum and elytra with setae. Pronotum unicolored, reddishbrown, widest at middle, posterior marginal line absent, lateral margin strongly convex and smooth (not serrate), antero-lateral angle dorso-ventrally flattened, postero-lateral angle dorso-ventrally not flattened, punctation on disc sparse, setae of lateral margin dense, median longitudinal excavation absent. Scutellum, punctures absent medially. Elytra unicolored, reddish-brown, surface opaque, microsculpture absent, punctation on intervals present and sparse, diameter of strial and interval punctation equal.
ABDOMEN. Lateral carina absent. Second visible ventrite without row of setae in medial region. Apical visible ventrite without suture to apical tergite.
LEGS. Ratio of length of metepisternum/metacoxa: 1/0.95. Metacoxa without longer lateral bristles, a laterally extended longitudinal shelf absent. Metatibia, widest at apex, ratio of width/length: 1/4.27, dorsal margin not carinated, ventral margin serrated, distal spines groups disposed at two thirds of metatibial length. First metatarsomere, ratio to dorsal metatibial spur: 1/2. Dorsal surface of tarsi glabrous, with punctures. Metatarsi, length of first protarsomere subequal to 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.
