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 Author Whitworth, Terry text Zootaxa 2010 2663 1 35 journal article 10.5281/zenodo.276279 280ecfda-718e-4b4c-b3a6-1077053c708c 1175-5326 276279 Lucilia rica Shannon Figs. 36 , 50–51 , 62–63 , 79–81, 87 , 94 Lucilia rica Shannon, 1926 : 132 Phaenicia rica : Hall, 1948 : 257 Lucilia rica : Woodley and Hilburn, 1994 : 13 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 ( Figs. 50–51 ). Phallus, ovipositor and other characters as described for L . eximia group ( 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 .

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 .
