Originally described from Puerto Rico, this species has since been 
recorded from Jamaica and is now recorded from Dominica and 
St. Lucia. 
The Dominican examples agree closely with the type except that 
the darker ventral processes of the subgenital plate are nearer its 
apex. The St. Lucian specimens seem to have a narrower and more 
twisted apex of the aedeagus and the dorsolateral process of the 
ninth segment has both dorsal and ventral points apically. 
Aputt.—Length of forewing 1.5-2 mm. Color mottled grayish 
brown; forewing of female with a patch of purplish iridescent scales 
centrally. Male genitalia: ninth segment produced basoventrally, 
posterior margin with a dorsolateral process whose tip is developed 
into a dorsal (and sometimes ventral) point; clasper elongate and 
rectangular in lateral view, in ventral view with apex obliquely 
truncate; bracteole slender, arising near base of clasper; subgenital 
plate elongate, slender, with dark, ventrally directed lobes at mid- 
length; aedeagus with a membranous process arising near midlength, 
and a more strongly sclerotized process near apex, central tube 
trough shaped apically. Female genitalia: eighth sternum with 
anterior margin heavily sclerotized, with a pair of short anterolateral 
rods, mesally with a heart-shaped lobe, and posteriorly with a rec- 
tangular sclerite, posterior margin with 3 pairs of setae; bursa copula- 
trix elongated apically, basolateral angles rodlike, with a basomesal 
complex.
