Diagnosis.

1.9-2.1 mm (mean = 2.0 mm; n = 5), 3.0-3.33 × as long as wide. This species is distinguished by the elytral apex attenuate and weakly emarginate, declivital interstriae 2 denticulate along the entire length, denticles on declivital interstriae 1 and 3 subequal, posterolateral margin of declivity with interstriae 3 and 9 joining, forming a carina and continuing submarginally to apex, declivital interstriae distinctly impressed, and anterior margin of pronotum without a row of serrations.

Distribution.

Colombia (Valle de Cauca), Costa Rica ( Limón), Dominica, Ecuador* (Orellana), Grenada, Guadeloupe, Martinique, Mexico (Campeche, San Luis Potosí, Tabasco, Veracruz), Panama ( Panamá), Peru (Loreto, Madre de Dios), Saint Lucia, Saint Vincent and the Grenadines, Trinidad, United States (Florida), Venezuela (Aragua, Mérida).

Biology.

This species is polyphagous and has been collected from Cordia ( Cordiaceae ), Hevea brasiliensis ( Euphorbiaceae ), Acacia ( Fabaceae ), Heliocarpus appendiculatus , Theobroma cacao ( Malvaceae ), Coffea ( Rubiaceae ), Cestrum ( Solanaceae ), Cecropia ( Urticaceae ) ( Wood and Bright 1992; Bright and Skidmore 1997; Wood 2007). Wood (2007) reported collecting the species from limbs and a log 5-20 cm in diameter. Specimens were also collected by canopy fogging.

Remarks.

Bright (2019) placed this species back in Xyleborus without discussion. This species clearly beongs in Coptoborus and shares the characters outlined in the generic diagnosis and has been shown to be correctly placed in Coptoborus , rather than Xyleborus in several molecular phylogenetic studies (e.g. Cognato et al. 2011; Gohli et al. 2017; Cognato et al. 2018).
