Gordonoryssomus mirnae sp. nov.

( Fig. 14 )

Description of holotype (male). Length 5.64, width 3.82 mm. Form elongate oval, widest at middle of elytra, not flattened dorsoventrally ( Fig. 14C ). General color reddish yellow ( Fig. 14A, B ). Outline of pronotum and elytron discontinuous. Pronotum and elytra without spots. Pronotum translucent at apex; finely, densely punctured; pubescence of semidecumbent yellowish hairs ( Fig. 14D ). Elytral punctures intermixed coarse and fine, dense, slightly larger than on pronotum; sparse in the discal area. Antenna, mouthparts, hypomera, epipleura, and legs reddish yellow. Metaventrite finely, sparsely punctured medially and anteriorly; coarsely, densely punctured laterally and posteriorly with punctures large, often confluent. Abdominal ventrites finely punctured, punctures separated by about a diameter or more, punctures becoming thicker laterally. First abdominal ventrite with postcoxal line slightly angulate, extending beyond middle of first ventrite ( Fig. 14E ). Genitalia simple; basal lobe longer than paramere, lateral margin thickened and abruptly widened in apical half, apex rounded; paramere slightly curved in lateral view, nearly parallel-sided ( Fig. 14G, H ); sipho curved and apex acuminate ( Fig. 14F ).

Female. Similar to male in all aspects externally. Genitalia with genital plates triangular, not elongate, styli with setae; spermatheca elongate, uniform ( Fig. 14I ).

Etymology. This species is named in honor of a great lepidopterist, Dr. Mirna Martins Casagrande.

Discussion. G. m i r n a e differs from the other species of the genus because it is the only species with uniform color pattern reddish yellow.
