Type material. Holotype male – “ Costa Rica: P[rovincia]. Cartago [locality actually in San José Province] / R. F. Los Santos / Sendero Los Robles / 9° 33’ 25.51 N 83° 47’ 55.47 W / 2400 m, 21-27 March 2004 / J.B. Sullivan & J.D. Lafontaine;” “Databased for CNC / NOCTUOIDEA # / 13709” [green label]; Barcodes of Life Project / University of Guelph / DNA # Noctuoidea / 13709” [blue label] GoogleMaps   ; HOLOTYPE / Leichosila   / talamanca / Schmidt” [red label]; deposited in INBIO   . Paratypes – 15 ♁♁, same data as holotype [ INBIO, CNC, JBS]   ; 5 ♁♁, Costa Rica, San Jose, Parc national Chirripo, sentier pédestre vers Mont Chirripo Km 4.7, 2310m, 1 V 2005, leg B. Vincent [white label]   ; BV 392 to BV 396 [white label]; [ BVC].

Diagnosis. Both Leichosila talamanca   and L. wagneri   can be easily distinguished from all other New World arctiines by the wing pattern and colour, consisting of a grey to whitish grey ground colour with a pattern of dark grey-black, incomplete forewing bands which are ochre yellow centrally ( Figs 1, 2 View Figures 1-2 ). Leichosila talamanca   differs from

L. wagneri   in its larger size, paler grey colouration of the wings, and internally by the more triangular uncus (parallel-sided in L. wagneri   , figs 6, 7), lack of a basal process on the costal margin of the valve ( Fig.3 View Figures 3-5 ), and a broadly joined pouch-like diverticulum of the vesica that is pointed and conical in L. wagneri   ( Figs 3b, 4b View Figures 3-5 ).

Description. A detailed description is given above in the generic description. Characters specific to L. talamanca   are as follows: Male (female unknown). Forewing – length averaging 15.4 mm (14.9-16.1 mm, n = 4); ground colour mouse grey to whitish grey. Hindwing – ground colour mouse grey to whitish grey, with irregular dark-grey subterminal spots, and medial spot. Male genitalia – Uncus triangular in dorsal view; vesica with left diverticulum of two ventro-basal diverticula pouch-shaped and broadly joined to main chamber of vesica ( Fig. 3b View Figures 3-5 ).

Etymology. This species occurs in montane broadleaf forest of the Cordillera de Talamanca, Costa Rica, hence the name.

Distribution and biology. Leichosila talamanca   is known only from two localities in the Cordillera de Talamanca. At the type locality, the habitat is dominated by mature oaks (D. Lafontaine, pers. comm.) within the Talamancan montane forest at 2400 m elevation. Collection dates are for the last week of March and early May.
