(toclypeal suture weakly bisinuate. Labrum with apex vertically produced with respect to clypeus, moderately produced medially with triangular tooth. Maxillary palpus with terminal segment enlarged, moderately elongate, with sulcus. Mentum with surface moderately setose, apex appearing bidentate. Antenna 10­segmented, club slightly shorter than combined basal segments. Pronotum: Midline absent. Surface moderately to densely punctate with moderately­sized punctures; moderately setose in apical half and along margins; setae long, slender, tawny to yellowish­brown. Scutellum: Surface moderately punctate, moderately setose; punctures moderately­sized; setae long, slender, tawny to yellowish­brown. Shape parabolic, 1.3 times wider than long medially. Elytron: Surface glabrous; longitudinal striae punctate, weakly impressed to not impressed; punctures moderately­sized, separated by 2–6 puncture widths. Intervals sparsely punctate with moderately­sized punctures. Epipleuron with row of thick setae present just ventral to bead. Pygidium: Width 2.0 times length medially. Surface weakly rugose; moderately setose; setae short to long, tawny to yellowish­brown. Venter: Thorax densely setose; setae long, tawny to yellowish­brown. Legs: Protibia with 3 subequally large teeth in apical half. Tarsal claws with modified claw ( Fig. 9 ) slightly thickened when compared with other claw, apex bifurcate. Tarsomere 5 without ventromedial tooth (similar to Fig. 6 ). Meso­ and metatibia with apical spurs slender, acute. Mesotibial apex with 15–17 spinules. Metatibial apex with 22–26 spinules. Parameres: Figure 13 . Basally with broad, medial furrow.

Female (n = 12): Length 13.0–19.0 mm. Width 7.1–10.1 mm. As male except in the following respects. Head: Antennal club shorter that combined basal segments. Legs: Tarsal claws ( Fig. 8 ) with modified claw with ventral tooth, not thickened when compared with other claw, apex not bifurcate. Metatibia with apical spurs slightly broader, blunter.
