Key to the species of Lucilia  of the West Indies

1. Three postsutural acrostichal setae; abdomen usually with apparent mesal division in which one half is microtomentose, the other half shining when viewed from a sharp angle laterally........................................................................ 2

- Two postsutural acrostichal setae; abdomen usually uniformly metallic or microtomentose ...................................... 3

2. Central occipital area with single seta just below inner vertical seta ( Whitworth 2006, fig. 73); abdomen dull coppery; humeral callus with two or three small setulae along posterior margin ( Whitworth 2006, fig. 74); metasternum bare; frons of male broad, much broader than width of parafacial at level of lunule, 0.20 (0.19–0.21) of head width; male genitalia (under Phaenicia pallescens  ) as in Hall (1948, fig. 24, J –M)................................................ L  . cuprina

- Central occipital area with two to five setae below inner vertical seta ( Whitworth 2006, fig. 73); abdomen usually bright green, occasionally shining coppery; humeral callus with six to eight small setulae along posterior margin ( Whitworth 2006, fig. 74); metasternum setose; frons of male narrower, about equal to width of parafacial at level of lunule, 0.13 (0.12–0.14) of head width; male genitalia as in Hall (1948, figs. 25 F, G); reported only from Bermuda. ....................................................................................................................................................................... L  . sericata

3. Fifth abdominal tergite coppery or aeneous (not always obvious, especially in some females); postocular area golden; body dark blue, sometimes with purple highlights; upper calypter white, lower calypter tan in both sexes;

basicosta tan; anterior abdominal tergites with tomentum including outer edges of T 4, the remainder polished; known only from Jamaica.......................................................................................................................... L  . lucigerens - T 5 usually not distinctly colored in contrast to other tergites; without above combination of characters. ................. 4

4. Rear half of gena with several to many pale setae in front of postgena ( Fig. 35View FIGURES 35 – 37) (note the postgena has pale setae in all Lucilia  in the region)................................................................................................................................................ 5

- Rear half of gena with only dark setae (rarely a few pale setae are found on rear edge of gena, not extending forward) ............................................................................................................................................................................. 6

5. Basicosta usually tan, sometimes light tan to orange. Rear edge of T 3, all of T 4 and T 5 polished when viewed from rear ( Fig. 36View FIGURES 35 – 37); male frons narrow, about 0.03 of head width, much narrower than width of first flagellomere. ............ ............................................................................................................................................................................. L  . rica

- Basicosta usually pale yellow or orange. Anterior third or more of T 4 with whitish microtomentum, rest of T 4 and T 5 polished ( Fig. 37View FIGURES 35 – 37); male frons much broader, about 0.10 of head width, broader than width of first flagellomere. .......................................................................................................................................................................... L  . cluvia

6. Basicosta pale orange, yellow or whitish...................................................................................................................... 7

- Basicosta darker, tan to black or sometimes orange-brown ......................................................................................... 9

7. Body color metallic-tan, appearing somewhat teneral; abdominal tergites all microtomentose; known only from six specimens from Bermuda, possibly extinct ........................................................................................... L  . problematica

8. Thorax green or blue, abdomen bluish-purple; T 4 and T 5 polished; male lower calypter dark brown; setae behind postocular row of setae weak and pale; surstyli broad, usually curved sharply inward ( Figs. 48–49View FIGURES 38 – 49); known only from Bahamas, Cuba, Cayman Islands and Dominican Republic............................................................. L  . retroversa

- Thorax and abdomen normally concolorous brilliant green; only rear edge of T 4 and all of T 5 polished; male lower calypter light tan; one irregular row of black setae behind postocular row; surstylus long and slender ( Figs. 40–41View FIGURES 38 – 49); listed from Cuba by James (1970), primarily southern USA, possibly introduced elsewhere ........... L  . coeruleiviridis

9. Upper and lower calypters gray to tan in both sexes; postocular area golden in good specimens, varying from faint to bright yellow; area may be darkened in poor specimens. Male frons narrow, 0.02 head width, usually less than width of median ocellus; male genitalia as in Figs. 44–45View FIGURES 38 – 49; known only from Puerto Rico, St. Vincent, Dominica and St. Lucia................................................................................................................................................................
