Key to species of Cochliomyia  of the West Indies

1. Genal dilation antero-dorsally with few to many short, black setae ( Fig. 21View FIGURES 21 – 28); T 5 cupreous, contrasting in color with preceding tergites ( Fig. 22View FIGURES 21 – 28); mesonotum with 3 broad black polished vittae alternating with narrower, gray microtomentose vittae ( Fig. 5View FIGURES 2 – 7. 2); postgenal setulae white........................................................................................................ 2

- Genal dilation with entirely yellow setae; T 5 blue to green, concolorous with preceding tergites; mesonotum with three black polished vittae alternating with about equal width green or blue microtomentose vittae; postgenal setulae yellow........................................................................................................................................................................... 3

2. T 5 with pair of median dorsal silvery microtomentose spots ( Fig. 22View FIGURES 21 – 28); occiput with few to numerous dark setae in upper part, just below postocular setae; frons of male narrower, 0.06 (0.05–0.065 / 8) head width, equal to or narrower than the width of first flagellomere; surstylus and cercus long and slender ( Figs. 31, 33View FIGURES 29 – 34. 29) ........................... C  . aldrichi

- T 5 with uniform dusting of microtomentum; occiput with pale setae only below postocular setae; frons of male broader, 0.083 (0.075–0.09 / 2) head width, width broader than width of first flagellomere; surstylus digitate, cercus with broad base tapering sharply to point ( Figs. 32, 34View FIGURES 29 – 34. 29) ............................................................................... C  . minima

3. Fronto-orbital plate with dark setulae outside row of frontal setae ( Whitworth 2006, fig. 53, right side); T 5 without pronounced silvery microtomentum; postgenal setae usually golden yellow; female with dark basicosta; proclinate orbital setae absent; not found in North America since 1966 due to eradication efforts; found in parts of Mexico, Central and South America, possibly in isolated areas in the West Indies ............................................ C  . hominivorax

- Lower third to half of fronto-orbital plate with pale setulae outside row of frontal setae ( Whitworth 2006, fig. 53, left side); T 5 usually with pronounced silvery microtomentum laterally; postgenal setae usually pale yellow; female usually with yellowish basicosta; usually with two pairs of proclinate orbital setae (sometimes only one on one or both sides). Widespread in Neotropical and Nearctic Regions ......................................................................... C  . macellaria
