Descriptions of four new species of Enaphalodes are included: E. antonkozlovi, sp. nov. from Costa Rica, E. bingkirki, sp. nov. from Nicaragua, E. monzoni, sp. nov. from Guatemala, and E. cunninghami, sp. nov. from Mexico. Enaphalodes senex (Bates, 1884) is revalidated and it is newly recorded from Nicaragua and Guatemala. A key to the 15 currently recognized species of Enaphalodes is included. Key-Words. Cerambycinae; Elaphidiini; Key; Long horned beetle; Taxonomy. INTRODUCTION Enaphalodes were known, with only two species known from Central and South America. The genus Enaphalodes Haldeman (1847) was In this work, we describe four new species originally listed in Dejean’s (1836) catalogue, but it of Enaphalodes: E. antonkozlovi from Costa Rica, is an unavailable name since it had no description E. bingkirki from Nicaragua, E. monzoni from or included species and therefore did not meet Guatemala, and E. cunninghami from Mexico.

Haldeman (1847) made the genus name available by describing a species, E. simplicicollis, within it. This species is currently a synonym of E. hispicornis MATERIALS AND METHODS (Linnaeus, 1767).
