Type locality. Brazil.

Taxonomic history. Godart [1824] described Satyrus periphas based on a single specimen [holotype] from Brazil, bearing no specific locality data. Westwood (1851) treats it as belonging to Neonympha Hübner, 1818 , based on adult morphological characters. Later, it is considered as a species of Euptychia by Butler (1867). Giacomelli (1928) described the variation ocellata based on specimens from Cosquin, Argentina. Lamas & Viloria (2004) transfer this species to Pampasatyrus and this classification is followed since then by several authors.

Diagnosis. Easily distinguished from Stegosatyrus ocelloides n. comb. by the larger size. The ocelli on ventral face of wings of S. periphas n. comb. are smaller than those of S. ocelloides n. comb.. On the ventral face of FW, the discal line is straight and joins with sub-marginal line close to 2 A, whereas in S. ocelloides n. comb. it is irregular and joins with CuA 2. On the ventral face of HW, the discal line of S. periphas n. comb. is straight and the marginal line is thinner than in S. ocelloides n. comb..

Redescription. MALE ( Figs 9 –10 View FIGURES 1 – 16 , 19, 22 View FIGURES 17 – 22 , 47–60 View FIGURES 47 – 60 , 78– 83 View FIGURES 72 – 83 ). Head ( Figs 19, 22 View FIGURES 17 – 22 , 78 –79, 82– 83 View FIGURES 72 – 83 ): Antenna light brown with 33 flagellomeres; frons with a tuft of elongated medium brown scales; labial palp with elongated white and black scales on ventral face, third segment thin with a pointed apex, a little longer than first segment. Thorax ( Figs 49 View FIGURES 47 – 60 , 80– 81 View FIGURES 72 – 83 ): with thin and elongated medium brown scales; prothoracic leg with coxae a little longer than total length of the others segments, femur more developed than tibia, tarsus the same length of tibia and with a pointed apex. Abdomen: dorso-laterally dark brown and ventrally light brown. Wings ( Figs 9 –10 View FIGURES 1 – 16 , 47 View FIGURES 47 – 60 ): dorsally medium brown and ventrally light brown. FW (length: 16–19 mm): external margin with medium brown fringes; Rs with length equal to dcs + dcm +dci; R 1 arises in discal cell, before dcs vein; R 2 and R 3 start together in R as a single vein and then branch out; sub-marginal region with a black ocellus between M 1 -M 3 externally surrounded with a yellow line and with a small nacreous pupil; ventral face with thin dark brown sub-marginal line between R 4 - 2 A, parallel to external margin, joining the discal line and surrounding the ocellus. HW: external margin with slight indentations and with fringes similar to those of FW; a black ocellus between CuA 1 -CuA 2 and another small one between CuA 2 - 2 A; ventral face with black ocelli between M 1 -M 2, CuA 1 -CuA 2 and another smaller one between CuA 2 - 2 A, two small nacreous pupils between M 2 -M 3 and M 3 -CuA 1, discal line straight and joining sub-marginal line at tornus. Genitalia ( Figs 51–58 View FIGURES 47 – 60 ): tegumen with median concavity at the proximal portion; ventral arm of tegumen straight and dilated at the middle portion; appendix angular reduced; anterior projection of saccus 2 / 3 the length of gnathos; apex of valva slightly crenulated; aedeagus thin with proximal portion lanceolate, a little longer than the valva.

FEMALE ( Figs 11 –12 View FIGURES 1 – 16 , 48, 50, 59– 60 View FIGURES 47 – 60 ). Similar to male. Head: Antenna with 35 flagellomeres.

Wings ( Figs 11 –12 View FIGURES 1 – 16 , 48 View FIGURES 47 – 60 ): FW (length: 15–20 mm): R 2 arises very close to dcs vein. Genitalia ( Figs 59–60 View FIGURES 47 – 60 ): Papillae anales a little longer than length of tergite VIII; sternite VIII fused with tergite VIII; lamella antevaginalis sclerotized; ductus bursae membranous; signa 2 / 3 the length of bursa.

Distribution ( Fig. 84 View FIGURES 84 ). Occurs in south Brazil (states of Paraná, Santa Catarina and Rio Grande do Sul) and in Argentina (being doubtful occurrence in Tucumán and Cósquin), from sea level to 1,400m. Flies throughout the year.

Host plants. Gramineae , Poa annua ( Varga, 1997; L. A. Kaminski, pers. comm.).

Oviposition and eggs ( Figs 65 –70 View FIGURES 65 – 71 , 72 View FIGURES 72 – 83 ). Eggs laid individually. Spherical eggs, without ornamentations, light yellow during the first few days, passing to cream with broad reddish bands and with a reddish spot in the micropilar area close to eclosion. Before hatching, the egg becomes translucent and it is possible to see the larvae. Height: 1.04 mm. Width: 1.04 mm (n= 24). Duration: 10–15 days.

First instar ( Figs 71 View FIGURES 65 – 71 , 73– 77 View FIGURES 72 – 83 ). Head capsule width 0.5 mm; height 0.8 mm; head scoli 0.1 mm (n = 10). Head capsule black, reticulate, with enlarged chalazae; bearing a pair of short scoli in the vertex. Third stemma larger than the other five stemmata. Body cream colored, smooth, with orange longitudinal stripes; caudal filaments very short. Setae dark, short, several dorsal and subdorsal clubbed at the tip. Legs and prolegs cream colored; abdominal spiracle globose. Larval length: 1.8 – 2.0 mm (n = 10 / DZUPIL 0122).

Remarks. After examining specimens in the collection of the Muséum National d’Histoire Naturelle de Paris and consulting Dr. Lamas (Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos, Lima, Peru), we concluded that the holotype is lost. Therefore, a neotype of Satyrus periphas is hereby designated to clarify the taxonomic status of the species and for nomenclatural stability.
