( Figs 14 , 22, 23 , 51 –57, 64)

Etymology. The species name is a patronymic in honour to the Peugeot company. The company started in 1999 the Peugeot-ONF Carbon Sink Programme project at the Fazenda São Nicolau, Cotriguaçú, Mato Grosso, Brazil.

Diagnosis. Males of H. peugeoti may be distinguished from others species by the following combinations of characters: disc of pronotum with strong greenish metallic sheen and smooth surface; sleek surface covering approximately one-third of pronotum width, surrounded by dense microtubercles, meanly on lateral and posterior portions ( Fig. 22 ). Aedeagus: [Ventral view]—inner margin at apical third of parameres with small lobe, wider than long (Fig. 55). Endophallus: Lateral lobe of A+SA sclerites with one-fifth of A+SA length, apex of lateral lobe abruptly narrowed (width of apex about one-third its basal width) ( Fig. 51 ). Horseshoe-shaped sclerite curved, with a shorter “arm” not expanded on its inner margin ( Fig. 54 , arrow).

Description. Length. 8.7–9.0 mm. Head. Surface around eye, in dorsal view, with brownish or greenish sheen; width of shiny surface approximately equal to that of eye. Pronotum. Margin between lateral and posterior angles approximately straight. Disc green with yellowish or greenish sheen ( Figs 22 ). Central portion of disc with oval, longitudinal and sleek band. Surface around band covered by dense ocellate microtubercles. Posterior surface of disc with a longitudinal depression and evident microgranulation ( Fig. 22 ). Elytra. Anterior portion of seventh elytral stria with inconspicuous elevation. Seventh stria narrower on basal sixth of elytra, carinate margins touching. Eighth stria inconspicuous and lacking punctures on basal half of elytra. Abdome. Disc of pygidium with longitudinal area of small shiny, sparse and irregular microtubercles, forming small 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 completely shiny and glabrous, with yellowish or greenish sheen; shiny surface narrowed on anterior portion of pronotum (width of shiny surface about one-fourth of pronotum width); posterior portion of disc with shallow longitudinal depression and almost inconspicuous microgranulation.

Aedeagus. [Lateral view]—parameres symmetric, rectangular in shape, with approximately two-thirds of phallobase length; apex of parameres, between apical and dorsal margins, with subrectangular projection, twice wider than long (Fig. 57). Inner angle between the apical and dorsal margins with approximately 90°. Inner angle between the apical and ventral margins with approximately 50°. [Dorsal view]—inner margins of parameres subparallels (Fig. 56). Endophallus: Complex of A+SA sclerites with elongate shape ( Fig. 51 ); anterior portion wider; FLP sclerite irregular, about two-thirds of A+SA length ( Fig. 52 ). SRP sclerite circular, with a conspicuous lobe projected outward ( Fig. 53 ).

Remarks. Specimens of the type series have the disc of pronotum with sleek surface covering approximately one-third of pronotum width; microgranulation on lateral and posterior portions ( Fig. 22 ). The specimens from Guajará mirim, Aripuanã, Porto Velho and Juína commonly have the pronotum almost completely glossy and shiny, with microgranulation only visible on lateral and posterior portions ( Fig. 23 ). 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. However, the specimens with the pronotum almost completely glossy have not been included in the type series.
