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. inornatus but has more elongate elytra 1.7-2.0 x as long as wide vs. 1.6 x as long as wide, and larger size 2.0-2.2 mm vs. 1.8 mm. Similar species. C. furiosa , C. inornatus , C. janeway , C. martinezae , C. vasquez . Distribution. Brazil (Bahia, Espirito Santo, Mato Grosso, Sao Paulo), Colombia (Huila, Santander, Tolima, Valle de Cauca), Costa Rica (Cartago, Limon , Puntarenas), Ecuador* (Orellana), French Guiana*, Mexico (Hidalgo, Oaxaca, Tabasco, Veracruz), Panama ( Cocle , Panama *), Venezuela (Barinas). Biology. This species has been recorded from diverse hosts including: Guatteria ( Annonaceae ), Protium ( Burseraceae ), Cordia ( Cordiaceae ), Inga ( Fabaceae ), Bombacopsis quinata , Heliocarpus appendiculatus , Theobroma cacao ( Malvaceae ) ( Wood and Bright 1992 ; Bright and Skidmore 1997 ; Wood 2007 ) and Cecropia ( Urticaceae ). Wood reported collecting specimens from limbs and branches 5-15 cm in diameter ( Wood 1982 , 2007 ). Specimens were also collected by canopy fogging. Remarks. Smith et al. (2017) reported this species from Peru (Madre de Dios). However this record represents a misidentification. The record is actually part of the type series of Coptoborus janeway from sample Peru 83b.
