Euptychia cesarense viloriai Andrade, Pulido, Peña & Lamas, new subspecies

(Figs. 2, 6)

Euptychia [n. sp.]: Lamas, 2004

Description. MALE, FW length: 17 mm (n=4) (Fig. 6 A).

Similar to nominotypical subspecies but DHW with an additional white-pupilled faint black ocellus in Cu2-2A, the lines below are narrower and the ventral ground color is paler (R194, G175, B86), in VFW the ocellus between R5 and M2 is smaller and the dark yellow patches between postdiscal and submarginal lines in M3-Cu1 and Cu1-Cu2 are nearly inconspicuous, in VHW the anal area between the inner margin and the postdiscal line is dusted with white scales. Ventrally, the discal, postdiscal, marginal and submarginal lines are thinner than those of nominotypical subspecies and submarginal line in both wings is more undulated in M2–Cu1.

Genitalia as in E. cesarense cesarense.

FEMALE, FW length: 17.2 mm (n=7) (Fig. 6 B): Ground color in both wings paler and more yellowish than in E. cesarense cesarense. DFW with a white pupilled black ocellus in M1-M2. DHW with white-pupilled black ocelli in M1-M2, Cu1-Cu2, and a faint one in Cu2-2A. Ventrally, the lines are wider than in E. c. cesarense, and the VFW patch between postdiscal and submarginal lines is more conspicuous.

Genitalia as in E. cesarense cesarense.

Early stages and host plants. Unknown.

Etymology. This subspecies is named after our friend and colleague Angel Viloria, in recognition of his important work on Andean Lepidoptera.

Diagnosis. Euptychia cesarense viloriai males are distinguished from the nominotypical subspecies by having a pupilled ocellus between Cu2-2A of DHW, the VHW anal area dusted with white scales, ventral ground color paler, ventral lines narrower, VHW discal line more oblique and submarginal line in the VFW apex in zigzag, rather different from the smoothly roundend line in the cesarense. Females can be separated by a general paler color, a pupilled ocellus in cell Cu2-2A of DHW and wider VW submarginal lines are evident.

Distribution and ecology. Known from Junín, Pasco and Cuzco in Peru. The subspecies flies from 1200 to 2100 m.

The existence of the species in several localities of Peru, and northern Colombia, suggests that Euptychia cesarense is a rare but widely distributed species in the Andes, with additional subspecies likely to be discovered in regions where it is currently unknown (Fig. 1). We compared additional material from Ecuador sharing features with cesarense and viloriai, which seems to be a different subspecies, but the status of these spcimen must be reviewed.
