Manerebia huamanii Cerdeña & Pyrcz , n. sp.

( Figs. 3 , 8 )

Type locality. Peru, Cajamarca Department, Tres Ríos

Diagnosis. This species might be confused, at first sight, only with the Colombian M. apiculata , which is of approximately the same size and shape in terms of the FW apex, and, to some extent, with the Ecuadorian M. interrupta . Both of these species apparently have individual forms with median half-moon shaped yellow patches. However, these patches in M. huamanii n. sp. are situated basally in relation to the postdiscal line, and distally in M. apiculata and M. interrupta , which makes the new species unmistakable. Considerable differences are apparent in the male genitalia, which show some similarities among M. huamanii n. sp., M. seducta , and M. ignilineata , including, among others, the stout uncus and massive basal parts of the valva. Molecular data are not available for M. huamanii n. sp. and no sister-species can be immediately identified, but its most closely related species should probably be looked for among those with the most similar genitalia.

Description. MALE ( Fig. 3C, D ): Head: Eyes chocolate brown, naked; antennae naked, reaching 2/5 th length of costa, slender with club formed gradually, dorsally chestnut, ventrally sandy yellow, labial palpi two and a half times length of head, covered dorsally with short, ventrally with long, dense brown and sparse yellow hair-like scales. Thorax: Black, dorsally naked, legs brown, tibia covered with brown scales, femur and tarsus with sandy yellow scales. Wings: FW length: 18 mm (n=2); apex acute, distal margin slightly truncate below apex. HW oval with a slightly produced apex. FWD almost uniform medium brown, with a slightly darker basal half. FWD medium brown. FWV medium brown, a shade lighter in distal half, a faint reddish suffusion in submarginal area. HWV reddish brown, with a magenta overcast along outer margin distal to a wavy brown submarginal line, basally edged with grey; a median series of four, half-moon shaped sandy yellow patches with sharp outer edges contiguous to a faint postdiscal line. Abdomen: Dorsally covered with medium brown, ventrally with grey brown scales. Genitalia ( Fig. 8B ): Uncus long and arched; gnathos one third length of uncus, with a stout base and sharp apex; pedunculus small, directed downwards, saccus medium long, flattened dorso-ventrally; valva stout in basal half with a blunt dorsal process, sharply narrowing into an elongated apical one-third ending with a series of three sharp processes pointing inwards; aedeagus nearly straight, prominently widened in middle, slightly flattened dorso-ventrally, similar in length to valva. FEMALE: Unknown.

Molecular data. Not available.

Type material: Holotype ♂: Peru, Cajamarca, Tres Ríos , 6 o 56'41''S 78 o 52'40'' W, 3163 m, 20. viii.2010, E. Huamaní leg., MUSM ; Paratype ♂: PERU, Piura, entre Las Minas y El Tambo, 2600–2900 m, 10–13.iv.1981, G. Lamas leg., MUSM .

Etymology. This new species is dedicated to Erick Huamaní Villalobos, the collector of the holotype and a member of the Museo de Historia Natural Universidad Nacional de San Agustín de Arequipa (MUSA), in recognition of his invaluable contributions to different projects of the MUSA. The name is treated as a Latinized masculine noun in the genitive case.

Remarks. The wing pattern characters, in particular the yellow patches situated basally in relation to the postdiscal line, and male genitalia, make this species unmistakable. The type locality lies on the western slopes of the Andes in the department of Cajamarca, half-way between two other localities where new species of Manerebia were discovered during this study, Abra de Porculla and Hacienda Udima ( Fig. 16 ). The second known specimen, which is associated with this species, comes from a more northerly locality in Piura, some 250 km away, also situated on the western slopes of the Andes. We were, unfortunately, unable to examine its genitalia. Its size, wing shape and colour pattern match those of M. huamanii except for the lack of any HWV yellow patches. The presence or absence of HWV median patches or bands is a common, highly variable individual character in the genus Manerebia . Such variation apparently occurs, for example, in M. interrupta , M. apiculata , M. ignilineata (Dognin, 1896) and M. trimaculata (Hewitson, 1870) , among other species.
