Diagnosis. Male frons 0.026 (0.02–0.035)/ 14 of head width, female frons 0.25 (0.24–0.26)/ 5. Basicosta usually tan, sometimes yellowish to orange; male upper calypter pale, lower tan, both calypters pale in female. Lower genal dilation with pale setae. Tarsi with the following pattern, t 1 1 p; t 2 1 a, 1 v, 2 p; t 3 no strong setae. Presutural area of thorax with microtomentum except polished in posterolateral corners; anterior abdominal tergites with microtomentum, rear edge of T 3, T 4 and T 5 polished.

Male genitalia in lateral view with surstylus parallel-sided, straight and digitate, broadly rounded distally; cercus tapering from a broad base to a point, longer than surstylus. In posterior view, lower one-third of surstylus curved inward; cercus long and straight ( Figs. 50–51View FIGURES 50 – 51). Phallus, ovipositor and other characters as described for L. eximia  group ( Figs. 62 –63View FIGURES 62 – 72. 62, 63, 79–81, 87View FIGURES 73 – 87. 73 – 81, 94View FIGURES 93 – 94).

Distribution. Specimens were examined from Antigua ( TW, USNM), Bermuda ( USNM), Guadeloupe ( CNC), and St. Lucia ( CNC, FSCA, UGG). James (1970) listed this species from Antigua, Puerto Rico, and possibly Haiti.

Discussion. Both sexes have pale setae on gena, a character shared only by L. cluvia  in the region. Much wider frons of male L. cluvia  is distinctive for males, see discussion under that species. Females of this species can be confused with female L. cluvia  because of the pale setae on lower gena. Pattern of microtomentum on the dorsum of abdomen normally separates females. There is some variation in specimens of L. rica  from Guadeloupe that have microtomentum in upper, outer corners of T 4, darker basicosta of L. rica  separates these specimens.

There is no evidence of L. rica  from outside the West Indies and Bermuda. I found this species to be quite common in Antigua from the desert-like shorelines to the subtropical forests in the mountains. Surprisingly, this is the only Lucilia  known from Antigua. Woodley and Hilburn (1994) also reported this to be the dominant species of Lucilia  in Bermuda.
