Adaina perplexus (Grossbeck, 1917)

Fig. 21 , 55

Diagnosis. Distinguished from Adaina ambrosiae by the light buff as opposed to mottled fuscous and white ground color on the wing base; discal spot and cleft spot small and well defined as opposed to dif- fusing into ground color; occipital fringe ochraceous-tawny as opposed to drab; dorsum of thorax with scales solid cartridge or light buff as opposed to light buff with drab tips; abdomen without fuscous lateral patches on segments A4 and A5. Male genitalia (figured by Matthews et al. 2012) are characterized by a distinct saccular process with a flattened blade-like base and narrow curved distal portion as opposed to a more lobed process in A. ambrosiae . The female genitalia ( Fig. 55 ) are distinct from A. ambrosiae in having a pair of elongate signa.

Preserved material examined. BAHAMAS: Long Island: Stella Maris , 1 mi. SE of airport, 23.575317°, −75.247100°, 31.v.2014, DLM, JYM, MJS, GJG, feeding on leaves of Melanthera (20 L, 1 LS, 2 P, 1 PC) ; same data except 31.v–1.vi. 2014 (17 L, 4 LS) ; South Andros Island: W of the Bluff Settlement 24.106939°, −77.557659°, 29.iii.2014, DLM, JYM, MJS, RMR, feeding on leaves of Melanthera (14 L, 6 LS, 3 P) (27 L, 5 LS, 5 P) {2 vials }.

Life history. Larvae feed externally on the leaves of Melanthera aspera (Jacq.) Small [ Asteraceae ]. Unlike A. ambrosiae , which also feeds on Melanthera Rohr , larvae loosely fold or draw together leaves with silk. The larva and pupa were illustrated by Matthews et al. (2012).

Distribution. Bahamas: Abaco, Cat, Long, San Salvador and North and South Andros Islands; Cuba: Varadero ( Gielis 2011); Trinidad; United States: Florida, Monroe and Sarasota counties.

Comments. Previously reported from North Andros Island ( Matthews et al. 2012).
