Coptoborus inornatus Wood, 2007: 399.

Type material.

Holotype (MEFEIS), not examined. Paratype (NMNH), examined.

New records.

None.

Diagnosis.

1.8 mm, 2.8 × as long as wide ( Wood 2007). This species is distinguished by the elytral apex attenuate and strongly emarginate, declivity convex, declivital interstriae 2 denticulate, elytral apex with interstriae 3 and 9 joining, forming a crenulate carina that continues submarginally to apex, declivital interstriae 3 with fewer than ten denticles, elytral apices acute, declivital striae not impressed, elytral apex crenulations large and coarse, declivital slope steep, occupying 50% of elytra. It is most similar to C. tolimanus but has stouter elytra, 1.6 × as long as wide vs. 1.7-2.0 × as long as wide, and smaller size, 1.8 mm vs. 2.0-2.2 mm.

Similar species.

C. furiosa , C. janeway , C. martinezae , C. tolimanus , C. vasquez .

Distribution.

Brazil ( Espírito Santo, Mato Grosso).

Biology.

Unknown.

Remarks.

Wood (2007) incorrectly reported the holotype’s location as MZUSP; the holotype is in MEFEIS. We examined the species description and images of a paratype but were unable to examine the holotype. Specimens of the type series do not share the same collecting event or locality. The holotype was collected from Mato Grosso, Brazil and the ten paratypes were collected in Espírito Santo, Brazil. The measurements of this species overlap almost entirely with those of C. tolimanus except in the elytral length width ratio, 1.6 × as long as wide vs. 1.7-2.0 × as long as wide. The body size is also likely identical given that Wood’s measurements were found to be 0.2 mm short (see methods). The slope of the elytra and elytral sculpturing is also identical. This species is almost certainly a synonym of C. tolimanus but the holotype should be examined to ensure that its morphology is congruent with that of the paratypes before it is formally synonymized.
