Gordonoryssomus everardoi sp. nov.

( Fig. 12 )

Description of holotype (male). Length 3.44, width 2.26 mm. Form elongate oval, widest at middle of elytra, somewhat flattened dorsoventrally ( Fig. 12 C). General color yellowish red, middle of thorax and abdomen dark brown. Outline of pronotum and elytron discontinuous. Pronotum yellowish red, with a basal triangular black spot, translucent at apex; finely, densely punctured; pubescence of semidecumbent yellowish hairs ( Fig. 12 D). Elytra yellowish red with a large black spot, extending from the base almost to the apex, reaching the middle of humeral callus ( Fig. 12 A). Elytral punctures intermixed coarse and fine, dense, slightly larger than on pronotum; sparse in the discal area. Antenna, mouthparts, hypomera, epipleura, and legs yellowish brown. Metaventrite finely, sparsely punctured medially and anteriorly, coarsely, densely punctured laterally and posteriorly with punctures large, often confluent. Abdominal ventrites coarsely punctured, punctures separated by about a diameter or less, punctures becoming coarser laterally ( Fig. 12 B). First abdominal ventrite with postcoxal line extending beyond middle of first ventrite; precoxal area coarsely punctured on base of cavity ( Fig. 12 E). Genitalia simple; basal lobe as longer than the parameres, lateral margin thickened and abruptly widened in apical half, apex bluntly pointed; paramere straight in lateral view, nearly parallel-sided ( Fig. 12 G, H); sipho flattened and rounded apex ( Fig. 12 F).

Female. Unknown.

Etymology. This species is named in honor of Dr. Everardo José Grossi, a doctor with a passion for beetles.

Discussion. The color pattern of this species is very similar with G. deyrollii , but it differs in body length, and also male genitalia, with basal lobe almost the same length as the parameres, and J-shaped sipho. It also differs from all other species of the genus by the color pattern and male genitalia.
