Figs 8 A-C,29B  
 Type material: male, Holotype: Honduras, El Paraiso, 6.8 km W Yuscarán, Cerro Monserrat (13°55'N, 86°24'W), 1760 m elev., under bark, 7.7.1994, leg. Ashe & Brooks, #019 (KNHM).   
 Diagnosis: Unfortunately, only the male holotype is known. Thus, the variation in size and colouration is unknown. Regarding the size, E. hondurana resembles E. humilis and E. boliviana. It is darker than E. humilis, which makes it similar to E. nigerrima. The elongate shape of the elytra and the colouration is similar as in E. boliviana. Without dissection of the aedeagus the species cannot be separated from the other related species of the group. In contrast to the related species, the central lobe of the aedeagus is more elongate and bears a short acute tooth in the apical part.   
 Description: Length: 2.6 mm. Colouration: blackish; elytra light brown with base and posterior margin blackish; legs and antennae light brown.   
Head: 0.39 mm long, 0.41 mm wide; eyes large, slightly prominent; as long as temples; temples smoothly narrowed to neck; preocular sides shortly parallel to base of antennae; anterior margin of clypeus sinuate; apically curved; deep supraocular groove reaching from anterior edge of eyes to posterior edge of temples; punctation moderately deep and irregularly sparse; interstices between punctures two to five times as wide as diameter of punctures; at each end of supraocular groove with large setiferous puncture; long setae yellow; elongate microsculpture deep; on clypeus partly diagonal; on vertex longitudinal and close to neck partly diagonal or transverse; surface slightly shiny.  
Antennae as long as head and pronotum combined; first antennomere thicker and longer than following antennomeres; second antennomere half as long as first; third antennomere slightly longer than second; following antennomeres increasing in width and decreasing in length; fourth antennomere slightly longer than wide; tenth antennomere slightly wider than long; fourth to eleventh antennomere pubescent and with long apical setae.  
Pronotum: 0.35 mm long, 0.39 mm wide; widest close to anterior angles; anterior angles rounded; sides in anterior half smoothly curved; nearly parallel; in posterior half evenly narrowed to posterior angles; at posterior margin approximately half as wide as at anterior angles; punctation similarly dense and deep as on head; at anterior margin close to anterior angles with three large setiferous punctures; long setae yellow; along lateral margin with several setiferous punctures; lateral margin interrupted; interruption marked by large setiferous puncture; microsculpture as deep as on head; striae elongate; on disc longitudinal; close to posterior angles diagonal; close to anterior angles nearly circular; surface slightly shiny.  
Elytra: 0.49 mm long, 0.46 mm wide; widest close to posterior angles; slightly narrowed; smoothly curved humeral angles; punctation as dense and deep as on head and pronotum; one large setiferous puncture on central disc; microsculpture as deep as on pronotum; meshes longitudinal; surface slightly shiny.  
Abdomen pubescent with several larger punctures with setae.  
Aedeagus moderately broad with short transparent lobes in apical half; apex obtuse; in lateral aspect, central lobe curved with acute apex; at midline of apical half with short triangular process; on both sides of process and close to base of process with several sensillae; anteriad of process few sensillae; parameres as long as central lobe; at apex with moderately wide transparent lobe; at outer side of transparent lobe with numerous short setae and one longer seta at apex.  
 Etymology: The species name derived from the country where it was collected.
