Fig. 22 , 57

Diagnosis. Forewing cleft at about 0.5–0.6× wing length from base; mottled drab and white; variable, with some individuals noticeably whiter. Costa with two fuscous dashes on first lobe near terminals of vein R 2 and R 3. R 2 dash obliquely connected to small spot at cleft base as a diffuse drab or fuscous mark. Small fuscous spots marking terminus of R 4 (apex), R 5 on first lobe and, M 3 (apex), Cu 1 in darker specimens. Hindwing drab. Male genitalia recognized by elongate, subequal anellus arms, a long saccular process equal or just exceeding length of left valve, and a small spine on the right valve saccular margin ( Bahamas specimen not available, see illustration in Gielis (2011)). Female genitalia ( Fig. 57 ) with a centrally placed funnel-shaped antrum, very short ductus bursae, and round corpus bursae lined with stellate spicules. Inception of ductus seminalis on anterior part of corpus bursae.

Pinned material examined. BAHAMAS: Crooked Island: 1.5 mi. E of Landrail Pt. , 22.813263°, −74.321186°, 7.vi.2015, MJS, GJG (1 ♀, slide DM 2097) ; North Andros Island : 2.4 mi. S of Staniard Creek, 24.797594°, −77.888264°, 27.x.2011, DLM, JYM, MJS, GJG (1 ♀, slide DM 1624) .

Life history. Unknown.

Distribution. In the West Indies, this species is known from The Bahamas, Cuba, Puerto Rico, and the Virgin Islands. In The Bahamas it has been collected on Crooked and North Andros islands. In south Florida it has been recorded from the Florida Keys and Florida City. Gielis (2011) also indicates records from Brazil and Mexico.

Comments. The specimen from North Andros was previously reported by Matthews et al. (2012) as “ Adaina sp.” Study of additional specimens from Cuba and Florida support the current species level determination.
