Phaenicia retroversa James, 1971: 382 . Holotype male (USNM, not examined). Type locality: Bahamas, Grande Island. Phaenicia retroversa: Mariluis et al. 1994: 26 .

Lucilia retroversa: Whitworth 2010: 26 ; Kosmann et al. 2013: 77.

Type information. The type series includes the holotype, an allotype, 5 male and 8 female paratypes. Two male paratypes were examined.

Diagnosis. Known only from the West Indies, where this species and L. cluvia are the only Lucilia with a pale orange basicosta ( L. sericata also has this character, but this species is only known from Bermuda near the West Indies). This species has dark setae on the gena to separate it from L. cluvia . See Whitworth (2010) for more details on this species.

Specimens barcoded. 2 females [BNNR183, 184], Grand Bahama Island, Freeport, West Indies , June 20, 1987, W.E. Steiner, M.J. & R. Molineaux ( USNM) . 1 male [BNNR048], 1 female [BNNR047], Dominican Republic, La Vega Cordillera Central , 4.1 km SW El Convento, May 31, 2003, J. Rawlins, et. al. ( CMNH) .

Discussion. James (1971) described this species from the Bahamas and Cuba. Whitworth (2010) studied a long series of specimens from the Dominican Republic that were similar to this species, but some differences were noted. It was originally thought these specimens belonged to a separate species, but detailed studies of specimens from each group led to the conclusion that differences were intraspecific variation. Four specimens were barcoded, two from the Dominican Republic, and two from the Bahamas ( Fig. 161 ). The barcode data supports the finding, though they are not identical, the two groups are very similar.

Distribution. Bahamas, Grand, New Providence, San Salvador; Cayman Islands, Cuba, Dominican Republic and Puerto Rico.
