Type locality. Brazil, Paraná, Castro.

Taxonomic history. Schaus (1902) described Euptychia ocelloides based on two syntypes, a male and a female, from the type locality. Brown & Mielke (1967) and Iserhard & Romanowski (2004) indicate this species as belonging to Megisto . Lamas & Viloria (2004) transfer the species to Pampasatyrus and, since then, this classification is followed by several authors.

Diagnosis. Among the species with similar color pattern, Stegosatyrus ocelloides n. comb. is easily distinguished from Megisto cymela (Cramer, 1777) by the irregular discal line on the forewing, the absence of an ocellus between M3-CuA1 and the thick and crenulated marginal line on the hindwing. Unlike M. cymela , the Stegosatyrus ocelloides n. comb appendix angular is small, the anterior projection of the saccus is longer than the tegumen, and the uncus does not have a down-curved apex.

Redescription. MALE ( Figs 5–6 , 18, 21 , 33, 35, 37–44 ). Head ( Figs 18, 21 ): Antenna light brown with 31 flagellomeres; frons with small white scales near the border of the eyes; labial palpi with elongated white and black scales on ventral face, third segment digitiform with same length of first segment. Thorax ( Fig. 35 ): tegulum with long, medium brown and white scales; prothoracic leg with coxae of same length as trochanter + femur + tibia + tarsus, femur more developed than tibia, tarsus same length of tibia. Abdomen: medium brown; sternite VIII rectangular. Wings ( Figs 5–6 , 33 ): light brown. FW (length: 13–16 mm): external margin with light brown fringes; sub-marginal region with a black ocellus between R5-M2 externally ringed with light brown line and two nacreous pupils; marginal region with dark brown line between R4-2A, parallel to margin; sub-marginal region with dark brown line rounding the R4-CuA2 ocellus; Rs of same length as dci vein; R1 arises at dcs vein base; similar ventral view. HW: external margin without indentations, but with fringes similar to the FW; a black ocellus between CuA1- CuA2; marginal region with irregular dark brown line between R1-2A; sub-marginal region with irregular dark line between M1-CuA2; ventrally face similar to dorsal face, differing in the presence of an ocellus between M1-M2 and another small one between CuA2-2A, irregular dark brown discal line parallel to margin between R1 and tornus. Genitalia ( Figs 37–44 ): tegumen with a pronounced median concavity in the proximal portion; ventral arm of tegumen angulated; appendix angular reduced; anterior projection of saccus of same length as gnathos; valvae without crenulation at apex; aedeagus approximately one and one half times longer than tegumen + uncus, narrow and with proximal portion lanceolate.

FEMALE ( Figs 7–8 , 34, 36, 45–46 ). Similar to male. Head: Antenna with 32 flagellomeres. Thorax ( Fig. 36 ): prothoracic tibia about 2/3 the length of femur. Genitalia ( Figs 45–46 ): Papillae anales 2/3 the length of tergite VIII; sternite VIII separated from tergite VIII; lamella antevaginalis sclerotized; ductus bursae with basal half sclerotized; signa 1/3 to 1/2 the length of bursa.

Variation. Some individuals can present a small black ocellus on the HWV, between M2-M3.

Distribution ( Fig. 84 ). Occurs in the south-west region of Paraguay (Hernandarias and Caaguazú) and the midwest, south and southeast regions of Brazil, from sea level to 1,500m. Flies throughout the year.

Host plants. Unknown.
