Name
Eucalantica pumila Sohn sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype ♂ – COSTA RICA: Heredia, Volcan Barva, 6 km ENE from Vara Blanca, 10°11' N; 84°07'W, alt. 1950–2050 m, 20 February 2002, BN-INB0003219355, GSN [SJC 808] (INBIO).
Diagnosis
This new species is easily distinguished from all other species of Eucalantica by its smaller size and in having a triangular, dark brown dorsal patch on the forewings. The male genitalia of Eucalantica pumila is similar to Eucalantica costaricae, but spines on the socii and the aedeagus is slender in the former.
Description
(Fig. 13).Forewing length 5.8 mm (n=1); costal streak on basal 1/10 of costal margin, black; dorsal patch subtriangular, dark brown, upper border extended to the lower side of the discal cell; terminal line with three dark brown dots between veins. Hindwing anterior margin 2.2× longer than maximum width, pale gray except dark gray apical area.
Male genitalia
(Figs 29, 30). Uncus subpentagonal, convex posteriorly, with a papilliform projection apically; socii semielliptical, straight ventrally, 1.5× longer than saccus, long-hairy dorsally, with four slender terminal spines in a row, gradually smaller from basal to terminal spine (Fig. 29b). Tegumen subtrapezoidal; subscaphium (Fig. 29d) slightly bulged. Valva elongate, of even width throughout, narrowly rounded apically; costa slightly convex at basal 1/3; sacculus ending at basal 1/4 of ventral margin of valva; an arched setal area above basal area of sacculus (Fig. 29c). Saccus slender, 2× longer than uncus. Aedeagus (Fig. 30) slender, narrower in distal half, almost straight, obtuse terminally; a zone of minute-spinulate cornuti 1/2 as long as aedeagus.
Female
unknown.
Distribution
Costa Rica (only known from the type locality).
Etymology
The specific epithet is derived from the Latin pumilus, meaning “little", and refers to its small size relative to other Eucalantica.
