Shannon, 1926 : 132 Hall, 1948 : 257 Woodley and Hilburn, 1994 : 13 Keys to the genera and species of blow flies (Diptera: Calliphoridae) of the West Indies and description of a new species of Lucilia Robineau-Desvoidy Whitworth, Terry Zootaxa 2010 2663 1 35 3WBZZ Shannon Shannon [151,410,1336,1362] Insecta Calliphoridae Lucilia Animalia Diptera 29 30 Arthropoda species rica     Lucilia rica  Shannon, 1926: 132    Phaenicia rica:  Hall, 1948: 257    Lucilia rica:  Woodley and Hilburn, 1994: 13   Diagnosis. Malefrons 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.  Malegenitalia 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. 50–51). Phallus, ovipositor and other characters as described for  L. eximiagroup ( Figs. 62–63, 79–81, 87, 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. cluviain the region. Much wider frons of male  L. cluviais distinctive for males, see discussion under that species. Females of this species can be confused with female  L. cluviabecause 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. ricafrom Guadeloupethat have microtomentum in upper, outer corners of T4, darker basicosta of  L. ricaseparates these specimens. There is no evidence of  L. ricafrom outside the West Indies and Bermuda. I found this species to be quite common in Antiguafrom the desert-like shorelines to the subtropical forests in the mountains. Surprisingly, this is the only  Luciliaknown from Antigua. Woodley and Hilburn (1994)also reported this to be the dominant species of  Luciliain Bermuda.
