This species is distinguished from all others in the group by the transverse pronotum (Fig. 90C), MPW/PL = 1.21-1.28, that is broad relative to the elytra, MEW/MPW = 1.35-1.39. Most similar to

can also be distinguished from that species by the distinct isodiametric sculpticells in transverse rows on the elytral disc and apex. Body coloration is darker as well, with the pronotal disc rufobrunneous to rufopiceous, and the elytra rufobrunneous, in some instances with an apical rufopiceous cloud. Setal formula 2 2 2 0. Standardized body length 3.2-3.7 mm.

of the ocular lobe, ocular lobe ratio = 0.75-0.79. The labrum is medially emarginate 1/5-1/6 of its length. The pronotal hind angles are obtuse rounded and little projected, the lateral margin only briefly subparallel before the angle. The pronotal median base is slightly depressed relative to the disc, but well set off by the dense elongate punctures and wrinkles, and the upraised isodiametric and transverse sculpticells over the surface. The elytral striae are well developed, with striae 1-6 and 8 complete and moderately deep on disc, stria 7 shallower. Striae 1-6 are distinctly punctate in basal

The 8th interval is broadly convex, slightly more so than inner intervals. The lateral elytral setae are arranged in an anterior series of 6 setae and a posterior series of 4 setae.

). Yet the only 20th Century record was a single specimen collected by beating vegetation at 1830-1980 m elevation (E.C. Zimmerman, BPBM). This species appears to have been a species of the forest edge (Fig. 94), with the historical collecting sites now extensively disturbed, the old forest edge gone.
