description: Hansreia grossii sp. nov.
(Figs 15, 24, 25, 58–63, 64)
Etymology. Named in honour of Paschoal Coelho Grossi, an enthusiastic scarabeidologist who collected specimens of the type series.
Material studied. Holotype: BRAZIL: AMAZONAS, Manaus, Reserva da Campina, (2°17'S, 60°02'W), VII.2008, Grossi— 1 ♂ (CEMT). Paratypes: BRAZIL: AMAZONAS, Manaus, Reserva da Campina, (2°17'02”S, 60°02'W), 13.VI.2008, Grossi— 15 ♂ 8 ♀ (CEMT); (2°17’S, 60°02”W), VII.2008, Grossi— 4 ♂ (CEMT); (2°35'29"S, 60°02'2"W), II.2009, F. B. P Gouveia et al. —4 ♀ (CEMT); same, Grossi— 1 ♂ (CEMT); BR 174 Km 115 (2°54’50.5”S, 60°02’09.7”W), 16.XI.1977, Norman D. Penny—1 ♀ (CEMT).
Diagnosis. Males of H. grossii may be distinguished by the following combination of characters: Body size less than 9.0 mm; disc of pronotum with weak greenish or yellowish metallic sheen and surface smoothly microgranulated (Figs 24, 25). Aedeagus: [Ventral view]—inner margin at apical third of parameres with small lobe, wider than long (Fig. 61). Endophallus: Horseshoe-shaped sclerite curved, with a shorter “arm” strongly expanded on its inner margin, claviform (Fig. 60, arrow). Lateral lobe of A+SA sclerites with apex bowed (Fig. 58).
Description. Length. 7.5–9.0 mm. Head. Dark brown with reddish or greenish sheen. Surface around eye with reddish sheen; shiny surface extends by approximately one-half of eye width in dorsal view. Pronotum. Margin between lateral and posterior angles approximately straight. Disc green with smooth yellowish sheen (Figs 24, 25) and conspicuous microgranulation and microtubercles, including on disc that present only a narrow, longitudinal and sleek single band. Microtubercles on disc less dense than on surrounding region. Posterior portion of disc with deep longitudinal depression and dense microtubercles (Figs 24, 25). Elytra. Anterior portion of seventh elytral stria with inconspicuous elevation. Seventh and eighth striae inconspicuous on basal fourth of elytra. Eighth stria narrower on anterior portion of elytra, carinate margins touching; stria with punctures only on posterior portion of elytra. Abdomen. Disc of pygidium with shiny, dense and confluent 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: most of pronotal disc microgranulated; shiny surface only on central portion of disc (width of shiny surface about one-fifth of pronotum width). 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, twice wider than long (Fig. 63). Inner angle between the apical and dorsal margins obtuse (>90°). Inner angle between apical and ventral margins with approximately 60°. [Dorsal view]—inner margin of parameres convergent at apex (Fig. 62). Endophallus: Complex of A+SA sclerites with elongate shape (Fig. 58); anterior portion wider; lateral lobe with one-fifth of A+SA length; apex of lobe bowed (width of apex subequal its basal width) (Fig. 58). FLP sclerite irregular, about two-thirds of A+SA length (Fig. 58). SRP sclerite circular, with a conspicuous lobe projected outward (Fig. 59).

Endophallus sclerites in Hansreia grossii sp. nov. 58—Complex of axial and subaxial sclerites (A+SA) (arrow left), and fronto-lateral peripheral sclerite (FLP), (arrow right); 59—Superior-right peripheral sclerite (SRP); 60— Horseshoe-shaped sclerite (short arm, arrow).
