Diagnosis. Male frons narrow, 0.025 (0.02–0.03)/ 7 of head width; female frons 0.26 (0.24–0.28)/ 10. Basicosta pale yellow to orange, inner edge sometimes tan. Male upper calypter light tan to whitish, lower calypter light tan to brown; female with upper and lower calypters white. Setae on tibia, t 1 1 p; t 2 1 ad, 1 av, 1 p to pv; t 3 with no prominent setae. Body color usually bluish; though the thorax is sometimes green and the abdomen is usually blue to blue-purple. Presutural area of the thorax mostly microtomentose, posterolateral areas polished; anterior abdominal tergites with tomentum, T 4 and T 5 polished. Male genitalia in lateral view with surstylus narrow at base, expanding broadly posteriorly in lower half; cercus tapering to a point from a broad base, much longer than surstylus. In posterior view, surstylus curved sharply inward, cercus short ( Figs. 48, 49View FIGURES 38 – 49). Phallus and other male characters and ovipositor are typical of the L. eximia  group ( Figs. 60 –61View FIGURES 52 – 61, 76– 78, 86View FIGURES 73 – 87. 73 – 81, 93View FIGURES 93 – 94).

Distribution. Specimens were examined from several Bahamas islands, including Grand ( USNM, WSUP), New Providence ( WSUP), and San Salvador ( USNM). Other locations include Cayman Islands ( UCD), Cuba ( BMNH, USNM), Dominican Republic ( CMNH, USNM) and Haiti ( USNM). A single specimen of this species was examined from Mayaguez, Puerto Rico ( USNM). It was reared from spoiled meat and collected by H.L. Dozier, Jan. 27, 1936. I examined numerous specimens from Puerto Rico and never found this species again. James (1972) listed this species from Bahamas and Cuba.

Discussion. A long series of specimens from the Dominican Republic is very close to L. retroversa  . The most obvious difference is the postocular area is yellow to gold and the lappets of the anterior spiracle are orange compared to Bahamian specimens, which have a silvery postocular area and a brown spiracle. After extensive comparison of morphology, including examination of male and female genitalia, it was concluded the differences are not sufficient to describe these specimens as a separate species.
