Diagnosis. Males of H. krinskii are readily distinguishable from others species by disc of pronotum completely sleek and shiny, with strong greenish and yellowish sheen; sleek surface covering approximately three-fourths of pronotum width ( Fig. 19 ). Posterior portion of disc with a narrow longitudinal depression; surface of depression with conspicuous microgranulation ( Fig. 19 ). Aedeagus [Ventral view]—inner margin at apical third of parameres with lobe twice wider than long (Fig. 48). 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. 45 ). Horseshoeshaped sclerite curved, with a shorter “arm” slightly expanded on its inner margin ( Fig. 47 , arrow).

Description. Length. 9.5–10.4 mm. Head. Dark brown with reddish sheen. Surface around eye with yellowish or greenish sheen; width of shiny surface approximately equal to that of eye in dorsal view. Dorsal surface of head with some ocellate punctures distributed randomly. Pronotum. Margin between lateral and posterior angles approximately straight. Disc completely sleek and shiny, with greenish or yellowish sheen ( Fig. 19 ). Elytra. Brown, with greenish sheen on base. Anterior portion of seventh elytral stria with inconspicuous elevation. Seventh stria inconspicuous on anterior portion of elytra; punctures visible. Punctures of eighth stria inconspicuous on anterior portion of elytra. Abdomen. Disc of pygidium with shiny, sparse and irregular microtubercles. Secundary sexual characters. Besides the sexual dimorphism mentioned to the genus, females of this species also present the pronotum completely shiny and glabrous, laking microgranulation. Elytral surface with distinct greenish sheen. Aedeagus. [Lateral view]—parameres symmetric, rectangular in shape, with two-thirds of the phallobase length (Fig. 50). Apex of parameres, between apical and dorsal margins, with rectangular projection twice wider than long. Inner angle between apical and dorsal margins obtuse (>90°). Inner angle between apical and ventral margins with approximately 40°. [Dorsal view]—Inner margin of parameres clearly convergent at apex (Fig. 49). Endophallus: Complex of A+SA sclerites with elongate shape ( Fig. 45 ); anterior portion wider; FLP sclerite irregular, about two-thirds of A+SA length ( Fig. 46 ). SRP sclerite circular, with a conspicuous lobe projected outward ( Fig. 46 ).
