( Fig. 12b , 13 , 16 )

Pseudeuptychia [n. sp.] Lamas MS ( Nymphalidae : Satyrinae 1475 ): Lamas 2004: 221.

Description. Male. unknown or unrecognized.

Female. Forewing length: 21 mm (n = 1)

Head: Eyes naked, with white scales at base; first segment of labial palpi white, adorned with white long hair-like scales and brownish long hair-like scales, second segment length almost twice as great as eye depth and covered with white hair-like scales and white scales laterally, and with black hair-like scales along edge of distal two-thirds of dorsal surface, ventrally adorned with black hair-like scales and some white hair-like scales about 3-4× as long as segment width, third segment about one-third of second segment in length and covered with black scales dorsally and ventrally, with creamy-white scales laterally; antennae approximately two-fifths of forewing length, with ca. 35 antennomeres (n = 1), distal 13–14 antennomeres composing club.

Thorax: Dorsally scattered with white scales and brown scales, greenish long hair-like scales present anteriorly, meso- and metathorax covered with sparse white hair-like scales; ventrally scattered with white scales and brown scales.

Legs: Foreleg whitish, first, second and third segments appear as distinct tarsomeres, fourth and fifth tarsomeres fused; midleg with femur white ventrally, tibia and tarsus greyish dorsally, tarsus ventrally ocher and tibia adorned with spines ventrally, pair of tibial spurs present at distal end of tibia.

Abdomen: See genitalia description below.

Wing venation: Basal half of forewing subcostal vein swollen; base of cubitus swollen; forewing recurrent vein absent; hindwing humeral vein developed; origin of M 2 slightly nearer M 1 than M 3.

Wing shape: Forewing triangular, apex rounded, costal margin slightly convex, outer margin almost straight, inner margin almost straight, but rounded towards thorax near base; hindwing slightly elongate, rounded, costal margin almost straight, angles inwards at base, outer margin convex, inner margin slightly concave near tornus, anal lobe convex, slightly round.

DFW: Ground colour light brown, distally darker, white coloration extending from base towards half way through discal cell, cells Cu 1, Cu 2, and 2A, slightly translucent, thus subtly revealing ventral ocelli in cell M 1.

DHW: Ground colour white, similar to white coloration on DFW, marginal area light brown, slightly translucent, thus subtly revealing ventral submarginal and marginal bands and ocelli in cells M 1 and Cu 1, distal side of ocelli marked with rufous tint.

VFW: Ground colour pale brown; pale reddish-brown discal band extends from radial vein, crossing discal cell, narrower below cubital vein, bent inwards and fading away before reaching 2A; whitish coloration along inner margin, extending up to origin of Cu; pale reddish-brown postdiscal band extending from radial vein towards inner margin until reaching vein 2A, slightly narrowing towards posterior end, bent outwards below Cu 2; broad, faint, indistinct dark shading covering middle of cells R 5, M 1, M 2, M 3, Cu 1, and Cu 2 (around submarginal ocelli); sinuate submarginal band, almost concolorous, extending from apex towards tornus, jagged above Cu 1, straight below this vein; concolorous marginal band, traversing along marginal area from apex to tornus; fringe brownish; ocellus in cell M 1, spilling out from veins M 1 and M 2, black with two slate grey pupils in center, ringed with orange, tiny satellite ocellus present in cell M 2, appears as slate grey patch surrounded by indistinct orange ring, small ocellus in cell M 3, similar to ocellus in cell M 1.

VHW: Ground colour similar to forewing; general wing pattern similar to forewing except as follows: discal and post discal band broader, postdiscal band inflated distally when traversing along discal cell; submarginal band jagged after Cu 1 and broadens towards tornus; five submarginal ocelli, those in cells M 1 and Cu 1 similar to that in VFW cell M 1, those in cells M 2 and M 3 similar to those in VFW cells M 2 and M 3, ocellus in cell Rs black with slate grey smudge-like pupil in center, ringed with orange.

Female genitalia ( Fig. 13c ): Lamella antevaginalis appears as a slightly sclerotized region surrounded by a membraneous area, somewhat semi-circular in ventral view; lateral sclerotized plate of 8th abdominal segment not fused with lamella antevaginalis at anterior margin; weakly sclerotized region present in ventral surface of intersegmental membrane of seventh and eighth abdominal segments; bursa copulatrix not examined due to damage in the abdomen.

Types. Holotype. FEMALE: PERU, CU[ZCO] VALLE DE MARCAPATA// MUSM-LEP 104263// Photographed By K. Willmott June 2015 // Genitalia vial SN-16-65 S. Nakahara // ( MUSM).

Etymology. The specific epithet is derived from the Spanish word ‘cuzqueña’, meaning ‘a woman from Cuzco’, in reference to the fact that this species is represented by a single female from Cuzco department. This specific epithet is treated as a latinized feminine noun in apposition.

Distribution. To date, this species is known only from the type locality, Valle de Marcapata, Cuzco, Peru.

Systematic placement and diagnosis. Although we do not have DNA data to justify the placement of this species in Pseudeuptychia , we describe this species in this genus due to its morphological resemblance to the other two other species placed in this genus, namely P. languida ( Butler, 1871) (type species) and P. hemileuca Staudinger, [1886] . All three species share a similar lamella antevaginalis which appears as a simple rounded plate surrounded by a membranous area. The female of Pseudeuptychia cuzquenya n. sp. is distinguished from the female of P. languida by lacking the prominent white area between the VHW discal band and postdiscal band, in addition to having the postdiscal band crossing the origin of Cu 1, whereas the postdiscal band is located distal to the origin of Cu 1 in P. languida . The lamella antevaginalis is similar to that of P. languida , but is distinguished by being semi-circular in ventral view, whereas this structure is somewhat oval in ventral view in P. languida . The male of P. cuzquenya n. sp. is unknown.
