Almeida, Lúcia M. & Santos, Paula B., 2014, Synopsis of Oryssomini Gordon (Coleoptera: Coccinellidae) from the Neotropical region with new species of Oryssomus Mulsant, Pseudoryssomus Gordon and Gordonoryssomus Almeida & Lima, Zootaxa 3846 (1) : -

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.
