Description.

Male. Body length: ca. 4.5-5.5 mm. Colouration: head mostly dark brown, except antenna and palpus which are yellow and genal dilation, which is brownish; head evenly covered with grey reflecting microtomentum. Scutum brown with three or four pale longitudinal vittae; thoracic pleura covered with silver reflecting microtomentum; tegula, basicosta light brown, calypters and wing membrane slightly infuscate; halter yellow; coxae and femora yellow; tibiae brown; tarsi dark brown; abdomen yellowish to light brown, weakly microtomentose. Head: frontal vitta 0.5-0.7 times as wide as fronto-orbital plate, both measured at approx. midlength. Ocellar triangle setulose, without ocellar setae. Postpedicel approx. 1.0-1.2 times as long as pedicel. Arista thickened in proximal 1/8-1/10; first and second aristomere approx. as long as wide. Frontal setae medioclinate, slightly proclinate near base of antenna. Median vertical setae short, 0.2-0.3 times as long as height of compound eye, crossed medially. Parafacial 0.8-0.9 times as wide as postpedicel. Facial ridge with few short setae above vibrissa. Gena, in profile, 2/5-1/2 as high as compound eye. Frons approx. 0.3 times as wide as compound eye in dorsal view. Prementum stubby, 1-2 times as long as wide; labella not elongated, normally developed; palpus exceptionally reduced. Thorax: two postpronotal setae; one posthumeral seta; 0 + 1 supra-alar setae (i.e., first and third postsutural supra-alar setae absent); 1 + 1-2 intra-alar setae; 2 + 3 dorsocentral setae (first presutural dorsocentral barely distinguishable from general setulae); acrostichal setae not differentiated. Fore tibia approx. 2 times as long as first protarsomere. Hind tibia with 3 dorsal preapical setae and 3-4 well-developed anterodorsal and posterodorsal setae. Costal sector cs2 setulose ventrally. Abdomen: tergite 5 approx. as long as tergite 4. Male terminalia: surstylus triangular in lateral view; cerci stout with a slight restriction at approx. mid length; apical 1/5 of cerci not pointed. Female. Female differs from male as follows: Head: fronto-orbital plate entirely shiny and parafacial with less dense microtomentum. Frontal vitta approx. 0.2 times as wide as fronto-orbital plate in female. Parafacial 1.2 times as wide as postpedicel. Frons approx. 0.9 times as wide as compound eye in dorsal view.

Distribution.

Neotropical - Trinidad and Tobago (Trinidad).

Etymology.

The species epithet is derived from the Spanish word for Caribbean and should be treated as a Latin adjective.
