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, t1 1p; t2 1a,
1v
, 2p; t3 no strong setae. Presutural area of thorax with microtomentum except polished in posterolateral corners; anterior abdominal tergites with microtomentum, rear edge of T3, T4 and T5 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 (

). Phallus, ovipositor and other characters as described for

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 T4, 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
.
