21. Lucilia setosa ( James, 1966)

Tables 1, 2

Phaenicia setosa James, 1966: 479 . Holotype male (USNM, not examined). Type locality: Ecuador, Galápagos, Darwin Island. Phaenicia setosa: James 1970: 11 .

Lucilia setosa: Kosmann et al. 2013: 77 ; Tantawi & Sinclair 2013: 239.

Diagnosis. The lower portion of the head does not extend downward or forward. The thorax and abdomen are metallic bluish or green and covered with a heavy whitish microtomentum; disc of T5 with stout black setae. The male frons is broad in this species, 0.16–0.17.of head width at narrowest, like other Galápagos Lucilia . Male genitalia are illustrated in Tantawi & Sinclair (2013, figs. 2E, 2F).

Description. See Tantawi & Sinclair (2013) and James (1966) for more details on this species.

Specimens examined. (7 males, 7 females). Ecuador: Galápagos Islands . 5 male, 6 female paratypes, Isla Darwin , Jan. 29, 1964, D.G. Cavagnaro ( WSUP) ; 1 female, same data except nonparatype ; 2 males, Española at Punta Juarez , Feb. 10–12, 1967, Ira L. Wiggins ( WSUP) .

Discussion. Two nonparatype male specimens from Española and collected by Ira Wiggins were examined (above). They had been identified as L. setosa by James, but differ from the paratype specimens I examined. The former specimens have a narrower frons with a head to frons ratio of 0.13/2 of head width at narrowest, than the five paratype males listed above with broader frons 0.174(0.16–19/5). They shared the stout discal setae on T5 with the paratype specimens from Darwin Island, but they appeared different in body color and microtomentum patterns varied. More material is needed for study from Española to clarify the identity of both the L. setosa -like specimens and the L. pionia -like specimens. Tantawi and Sinclair (2013) have examined additional specimens from the same series collected by Ira Wiggins from Española and identified as L. setosa by James. They placed all the Española Lucilia specimens, other than L. deceptor , under Lucilia sp. near L. pionia .

Distribution. James (1966) listed from Ecuador, Galápagos Islands, Darwin Island (Culpepper) and Wolf Island, but is likely to occur on other islands.
