Type material.

Holotype ♂ - COSTA RICA: Heredia, Volcán Barva, 6 km ENE from Vara Blanca, 10°10'34"N; 84°06'41"W, alt. 1950-2050 m, 16 February 2002, BN-INB0003220413, GSN [SJC 642] (INBIO). Paratype ♂ - COSTA RICA: same locality as holotype, 21 March 2002, A Kawahara, BN-INB0003217116, abdomen missing (INBIO).

Diagnosis.

This species is very close to Eucalantica icarusella in the shape of the dorsal patch of the forewing and in having entirely pale gray forewing fringes but differs from the latter by having most of the black dots sparsely scattered beyond the discal cell. Eucalantica ehecatlella is further distinguished from Eucalantica icarusella by the lack of projections near the apex of uncus in the male genitalia.

Description

(Fig. 6). Forewing length 5.0-6.2 mm (n=2) with dark brown costal streak in basal 1/4; posterior suffusion on basal half of dorsal margin, reddish brown with an intermittent, black line along upper border; black spots sparsely scattered on distal 1/4; terminal line narrow, black, intermittent; fringes pale orange, paler on tornus. Hindwing anterior margin 2 × longer than maximum width; fringes pale gray.

Male genitalia.

(Figs 21, 22) (1 preparation examined). Uncus (Fig. 21a) elongate, triangular, conical apically; socii bulged dorsally, sharp triangular in terminal 1/5, 1.5 × longer than saccus, long-hairy dorsally, with four terminal spines in a row, third spine from tip longest, followed by second, fourth, and first in order of length (Fig. 21b). Tegumen parallel-sided; subscaphium (Fig. 21d) slightly bulged ventrad. Valva obovate, costal margin almost straight, apex broadly round; a semicircular ema rgination adjoining with a densely setose area and an oblique groove above saccular base (Fig. 21c); a subrectangular emargination near the middle of the base of valva ventrally (Fig. 21c). Saccus elongate, digitate, as long as uncus. Aedeagus (Fig. 22) of even width throughout, strongly curved medially, with a triangular carina terminally and a zone of minute-spinulate cornuti 1/3 as long as aedeagus.

Female.

Distribution.

Etymology.

The specific epithet is derived from 'Ehecatl', a god of wind in Aztec mythology and refers to the windy habitat where the new species was collected.
