Figs 1–3 MATERIAL. Holotype ♂ : Brazil , Rondônia , Ouro Preto , 22.III.1979 leg. A.C. Mendes ( MCNZ ) . DESCRIPTION. This species is very similar to E. hevera in dorsal aspect and size ( Fig. 1 ); it can be distinguished by the morphology of the pygophore especially by the structure of parameres and segment X. ( Figs 2–3 ). Measurements: total length 6.15, head length 1.06, anteocular length 0.41, pronotal length 1.47, scutellar length 2.29, head width 1.80, interocular width 0.90, interocelar width 0.36, pronotal width 3.93, scutellar width 2.29, abdominal width at third segment 3.93, antennal segments missing. Dorsal surface matte, darker than in E. hevera ; disc of scutellum and corium with wider dark brown spots; membrane of hemelytra heavily infuscate. Lateroventral thirds of abdomen with dark brown spots in addition to the oblong spot on median third. Male genitalia. Pygophore subquadrangular, posterolateral angles developed; lateral thirds of dorsal rim heavily depressed, inner wall of genital cup tumescent, posteriorly triangular, surpassing postero-lateral angles of pygophore. Parameres quadrangular in dorsal view, juxtaposed along mid line, and covering the base of the platelike and wide segment X; apical margin of segment X * Contribution No. 484 of the Department of Zoology, UFRGS.

Inferior fold of ventral rim of pygophore with a deep semicircular excavation; superior fold sinuate, median third with a U-shaped notch bearing a denticle at middle ( Fig. 3 ). ETYMOLOGY. This species is named in honor to Dr. Izyaslav Kerzhner for his outstanding contribution to the knowledge of the true bugs.
