Diagnosis. Males of H. affinis may be distinguished from others species by the following combination of characters: Body size less than 9,2 mm ( Fig. 10 View FIGURES 10 – 15 ); disc of pronotum with strong greenish or yellowish metallic sheen and smooth surface on its central portion ( Figs 10 View FIGURES 10 – 15 , 16, 17). Aedeagus [Ventral view]—inner margin at apical third of parameres with lobe as wide as long (Fig. 29). Endophallus: Lateral lobe of A+SA sclerites with one-fifth of A+SA length, apex of lateral lobe slightly narrowed (width of apex about one-half its basal width) ( Fig. 26 View FIGURES 26 – 28 ). Horseshoe-shaped sclerite curved, with a shorter “arm” strongly expanded on its inner margin, claviform ( Fig. 28 View FIGURES 26 – 28 , arrow).

Description. Length. 8.0– 9.2 mm. Head. Surface around eye with brownish or greenish sheen; shiny surface extends by approximately one-half of eye width in dorsal view. Pronotum. Margin between lateral and posterior angles approximately straight. Disc with strong greenish or yellowish metallic sheen and smooth surface on its central portion. Surface around disc covered by dense ocellate microtubercles, mainly on lateral and posterior portions; disc with median longitudinal depression on posterior portion, triangular shaped; surface of depression with microgranulation ( Fig. 16). Elytra. Anterior portion of seventh elytral stria with inconspicuous elevation. Seventh and eighth striae inconspicuous on basal sixth of elytra. Eighth stria narrower on anterior half of elytra, carinate margins touching. Abdomen. Disc of pygidium with shiny, dense and irregular microtubercles, forming conspicuous shiny zones. Secondary sexual characters. Besides the sexual dimorphism mentioned to the genus, females differs from the males in the following aspects: disc of pronotum almost completely shiny and glabrous; anterior portion of pronotum with shiny surface restricted to a narrow longitudinal band (with about 1/10 width of pronotum); posterior portion of the disc with a longitudinal and shallow depression. Aedeagus. [Lateral view]— parameres symmetric, rectangular in shape, with approximately two-thirds of phallobase length; apex of parameres, between apical and dorsal margins with rectangular projection, longer than wide (Fig. 31); Inner angle between the apical and dorsal margins with approximately 90°. Inner angle between the apical and ventral margins with approximately 40°. [Dorsal view]—inner margins of parameres sub-parallels (Fig. 30). Endophallus: FLP sclerite with irregular shape, about two-thirds of A+SA length ( Fig. 26 View FIGURES 26 – 28 ). SRP sclerite circular, with a conspicuous lobe projected outward ( Fig. 27 View FIGURES 26 – 28 ).

Remarks. In the original description Fabricius (1801) only mentioned “ America Meridionali” [South America] as the type-locality to Ateuchus affinis . However, the specimens collected by Smidt exhibit the following label data: “ Essequibo ”. According to Papavero (1971), Smidt had visited several Caribbean islands and continental regions close to those islands, for example, Essequibo and Demerara (both currently belonging to Guyana). Therefore, according to Papavero, all the specimens collected by Smidt in the South American regions can be considered from Essequibo and Demerara region. Specimens from Guyana (close to the type locality) have the disc of pronotum with strong greenish or yellowish metallic sheen and smooth surface on its central portion, covering approximately one-third of pronotum width; microgranulation on lateral and posterior portions ( Fig. 16). The specimens from Amapá commonly have the pronotum with two sleek bands surrounded by dense microtubercles and microgranulation; disc with median longitudinal depression on posterior portion ( Fig. 17). We have found no significant difference in the male genitalia between these two forms. Therefore, to date, we prefer to consider this pronotum variation as an intraspecific character.
