Etymology.

Dunama biosise is named in honor of BIOSIS, the non-profit publishing company, the sale of which generated the JRS Biodiversity Foundation (http://www.jrsbdf.org), which in turn supports biodiversity information management for conservation in many places, including INBio and ACG.

Diagnosis.

St8 wide, short, anterior margin simple, posterior margin sclerotized with a pair of forceps-like processes, a small and sclerotized triangular projection at the base of each process. Phallus with subbasal, unsclerotized expansion, distal half narrow and sclerotized.

Description.

Male (Figs 47, 48, 51-53).Head - Antenna pectinate in basal 4/5, rami moderately long, reddish brown, distal fifth simple, shaft cream colored, scape with scale tuft reddish brown and cream colored; frons with cream scales mixed with reddish-brown scales; labial palpus upcurved reddish brown with a few scattered cream-colored scales; ocelli absent; vertex reddish brown, cream colored laterally; patagium blackish brown near the midline, blackish brown laterally, margins cream colored. Thorax and abdomen - Tegula cream colored at base, a mix of cream and reddish-brown scales distally; mesoscutum blackish brown anteriorly, cream and blackish brown posteriorly; mesoscutellum mostly creamy white; thoracic pleuron cream colored; legs mostly blackish brown on outer surfaces, cream-colored on inner surfaces. Abdominal dorsum light gray, venter cream colored. Wings - Dorsal ground color a mixture of gray-brown and beige scales; veins lined with gray, especially distally; anal fold and cubitus ligth brown; orbicular spot diffuse blackish brown; M-line diffuse blackish brown; AD-line with ligth brown spots, fringe gray brown. Dorsal hindwing dirty gray brown, lighter near base. Ventral surfaces of both wings gray brown (Figs 47, 48). (WL 11.7-12.8). Male genitalia - (Figs 51-53). Tg8 oval, posterior margin narrroly sclerotized; St8 wide, short, anterior margin simple, posterior margin sclerotized with a pair of forceps-like processes, a small and sclerotized triangular projection at base of each process (Fig. 51). Uncus lobule-like and elongate with thin, pubescent socci, up-curved. Valva with costal margin smooth, bearing an apical spine-like projection, long and sclerotized; saccular margin serrate and heavily sclerotized at base, with laminate-like structure (Fig. 52). Phallus with subbasal unsclerotized expansion, distal half narrow and sclerotized. Vesica small, without cornuti (Fig. 53). Female (Figs 49, 50, 54). Antenna filiform, shaft cream colored; body color and wing pattern similar to male but wings longer (Figs 49, 50). (WL 13.9 mm). Female genitalia - (Fig. 54) segment 8 forming a heavily sclerotized capsule; anterior apophyses acute; posterior apophyses tiny, CB small and round, signum absent; DB short; ostium recessed in St8. Ovipositor lobes acute and slightly pubescent.

Natural history.

Unknown, except that it is a moth of Costa Rica’s lowland Pacific coast rain forest and both sexes can be captured at light at night.

Distribution.

Dunama biosise has been collected from 0 to 100 m elevation in the Osa Peninsula, Area de Conservacion Osa (Fig. 85).

Remarks.

The single sample submitted for barcode analysis produced only a 349 base pair DNA barcode instead of the hoped-for 658 base pairs (Fig. 86). However, its barcode differences, and its distinctive genitalia, as well as the ecosystem it occupies, all indicate that it is a species distinct from the other known Costa Rican Dunama .
