COSSULA DUPLEXATA SP. NOV.
( FIGS 43 View Figures 32–43 , 81, 82 View Figures 77–88 , 103 View Figures 101–106 , 143)
Male ( Fig. 43 View Figures 32–43 ): Forewing length: 22 mm.
Head: Antenna light brown; labial palpus rustybrown dorsally and ventrally; frons rusty-brown; vertex dark rusty-brown to fuscous.
Thorax: Patagia same colour as vertex; tegula and dorsum mixed with white, brown and fuscous scales; pleura mostly brown, with some white along base of forewing; venter mostly brown, mixed with creamy white and light brown; a dark brown to fuscous patch below labial palps, ventrally. Legs mostly rustybrown, lighter brown mesally. Forewing a mix of different shades of brown dorsally, mixed with creamy white; several short fuscous striae traversing wing, with few striae along costal and inner margins; an elongate fuscous spot beginning at base of discal cell and extending towards inner angle; terminal patch with outer margin greyish brown and inner margin dark brown to fuscous; a brown to fuscous spot separate from terminal patch between CuA 1 and CuA 2; fringe different shades of brown; forewing mostly brown ventrally, with a mix of cream along wing; costal margin cream and brown banded. Hindwing brown dorsally and ventrally; fringe different shades of brown.
Abdomen: Brown to dark brown dorsally and laterally; mostly light brown and cream ventrally; A7–8 light brown and cream.
Male genitalia ( Figs 81, 82 View Figures 77–88 , 103 View Figures 101–106 ): Valva oblong and rounded apically; length of valva approximately 0.7¥ length of genital capsule; gnathos–uncus expanse approximately 0.03¥ length of genital capsule; sacculus with a lenticular ridge running lengthwise and developing terminally into a blunt spinose process; juxta process elongate and wide; gnathos arms short; gnathos bridge elongate and narrow, broadly downcurved as viewed laterally, subacute terminally and apressed to uncus; uncus elongate and narrow, downcurved with gnathos bridge, with apex truncate and shallowly bifurcate. Aedoeagus becoming wider towards rostellum, as viewed laterally; rostellum short, knob-like and blunt apically; vesica with a dense covering of small spines at distal end where ductus ejaculatorius emerges.
Female: Unknown.
Distribution: Known only from the type locality, Costa Rica.
Holotype: ♂; COSTA RICA: CARTAGO: Moravia de Chirripo , 1100 m: 16.iv.1983, A. M. Chavarria, slide USNM 96036 About USNM ( INBio).
Host: Unknown.
Flight period: April (unique record).
Etymology: Derived from the Latin suffix ‘-atus’ meaning ‘imitate’ or ‘copy’. Cossula duplexata refers to its similarity to C. duplex .
Discussion: This species most closely resembles C. duplex in wing pattern and colour, and an undescribed species from Brazil in male genital morphology. Cossula duplexata differs from duplex in possessing a smaller, fuscous scale patch at the base of the forewing discal cell ( Fig. 43 View Figures 32–43 ). The male genitalia of duplexata differs from the Brazilian species in possessing a more curved, caudal apex of the gnathos and in the distinctly shorter, broader saccular process of the valvae ( Fig. 81 View Figures 77–88 ). In the Brazilian species the gnathos is not curved and the saccular process is long and slender.
