SPINULATA MANES ( DRUCE, 1898) COMB. NOV.

( FIGS 26, 27 , 61, 62 , 93 , 111, 112 , 138)

Arbela manes Druce, 1898: 450

Cossula manes Druce, 1898 . Donahue (1995: 126)

Male ( Fig. 26 ): Forewing length: 19 mm.

Head: Antenna light brown; labial palpus light brown ventrally, dark brown dorsally; frons cream irrorated with brown; vertex light rusty-brown.

Thorax: Patagia same colour as vertex; dorsum of prothorax and tegula same colour as patagia and becoming cream, irrorated with light brown towards metathorax; pleura cream irrorated with light brown; venter brown irrorated with cream and light brown. Legs cream mesally, and dark brown laterally; tarsi same as femur and tibia. Forewing light brown dorsally, with brown and light rusty-brown striae alternating along entire wing length; costal margin with numerous short fuscous striae; fringe banded light brown and cream. Forewing mostly brown ventrally, with faint brown striae and short fuscous striae along costal margin. Hindwing brown dorsally and ventrally; fringe whitish cream.

Abdomen: Rusty-brown dorsally; pale rusty-brown ventrally.

Male genitalia ( Figs 61, 62 , 93 ): Valva subtrapezoidal, approximately 0.8¥ length of genital capsule, with sides and edges rounded; gnathos–uncus expanse approximately 0.8¥ length of genital capsule. Saccular process with an elongate patch of spines. Juxta process flattened and mostly fused to valva. Gnathos almost semicircular in shape, with lateral sides slightly upcurved. Uncus elongate and digitiform, with acute apex. Aedoeagus strongly curved, tapering to a slender, acute apex as viewed laterally; apex rounded as viewed ventrally.

Female ( Fig. 27 ): Forewing length: 21 mm.

Head: Antenna same as male; labial palpus light brown ventrally, dark brown dorsally; frons and vertex light rusty-brown.

Thorax: Patagia same as vertex; tegula light rustybrown; dorsum cream, interspersed with light brown; pleura and venter creamy light brown. Legs creamy light brown mesally and dark brown laterally; tarsi same as femur and tibia. Forewing with similar dorsal and ventral pattern as male, but with striae on costal margin not as dark and overall wing hue lighter; fringe mostly cream with some light brown. Hindwing light brown dorsally and ventrally; fringe creamy white.

Abdomen: Light golden brown dorsally and ventrally, with a darker brown patch on A2–3 dorsally.

Female genitalia ( Figs 111, 112 ): Sternite 8 reduced and mainly membranous, mostly covered by intersegmental membrane; intersegmental membrane between abdominal sternites 7 and 8 with sclerotized cuticular wrinkles and folds above ostium, and forming an elongate and flattened tube along basal quarter of ductus bursae near ostium; ductus bursae slightly elongated and sclerotized along terminal quarter of length near ostium; corpus bursae small and spherical, approximately 0.5¥ length of bursa copulatrix.

Distribution: Central and north-western South America, from Costa Rica, Panama and Colombia.

Holotype: PANAMA: Chiriqui, (Staudinger Collection at Humboldt Museum, Berlin, Germany) [not examined].

Material examined: COLOMBIA: Valle: Anchicaya Valley : 1 ♂, 650 m, 2.ii.1989, J. Bolling Sullivan, slide USNM 85730 ( USNM) . COSTA RICA: CARTAGO: Grano de Oro, Chirripo , 1120 m: 1 ♀, 4.x.1992, J. F. Corrales, ( INBio) . PUNTARENAS: Rancho Quemado, Península de Osa , 200 m: 1 ♂, xii.1992, F. Quesada, ( INBio) . SAN JOSÉ: Estación Bijagual, 500 m, Res. Biol. Carara : 1 ♀, xii.1989, R . Zuniga , slide USNM 85657 ( USNM) .

Host: Unknown.

Flight period: October to December in Costa Rica; February in Colombia.

Discussion: Spinulata manes is similar to other members of Spinulata in the presence of transverse striae on the forewing, but differs in the absence of distinct forewing spots.

Comments: Although the holotype was not examined in this study, species identification was made based on descriptions and illustrations, both original and from Dyar & Schaus (1937, in Seitz).
