New synonymy. Based on Blanchard’s (1938) description and figures of the male genitalia of his new species Lucilia littoralis, this nominal species is synonymized with Musca eximia Wiedemann, 1819, syn. nov.
Diagnosis. A widespread and somewhat variable species found from the southern United States to southern South America. One of six species where the upper calypter is white and the lower brown in males while both the upper and lower calypters are white in females. Where ranges overlap in southern South America, it may be confused with L. ochricornis. To separate them, L. eximia has pale and weak setae below and behind the strong postocular row (as in Fig. 3) vs. setae dark and stout (as in Fig. 4); male frons narrower, averaging 0.04 (0.03–0.05/ 19) of head width at narrowest vs. broader, averaging 0.06 (0.05–0.075/5) of head width; male genitalia are distinctive in lateral view the surstylus is of medium length, narrower at the base with distal half expanded (Fig. 41).
Description. In male, anterior and posterior facets both small, anterior facets 1.8x posterior facets (0.40mm, 0.27mm); females eye facets very similar to males except anterior facets are slightly larger (0.48mm, 0.27mm). See Hall (1948) and other authors listed above for more characters for this species. See Whitworth (2010) for a detailed discussion of characters and character states for this species. See Figs 41, 42, 65, 66, 90–92, 124 herein for views of male genitalia, phallus, hypandrium, ejaculatory sclerite and sternite; see Figs. 136, 148 for views of ovipositor and spermathecae.

Tantawi & Sinclair (2013) recorded this species for the first time from four Galápagos Islands.
Discussion. This species was common in many areas and somewhat variable, it has been described as different species by numerous authors, see synonyms above. Mello (1961) listed Phaenicia ochricornis, P. mera, and P. primaveris as synonyms of L. eximia, these were misidentifications. This species was the most frequently encountered species of Lucilia in most of the Neotropical Region and it occurs over a large geographical area. It is likely found in every country through Central and South America from Argentina north.
Barcodes for 28 specimens of this species were obtained from Belize, Bolivia, Brazil, Costa Rica, Dominica, Honduras, Puerto Rico, Venezuela, and from the United States (Louisiana and Texas). Specimens grouped into several discrete clusters, widely separated (Fig. 161). This raised the possibility that some of these groups are cryptic species. A study of specimens within groups revealed some variation in morphology, but, in my opinion, none of the differences merited the description of separate species. See Whitworth (2010) for a discussion of differences seen between West Indies and mainland L. eximia. A possible explanation for the variation in barcodes for this species is that isolated populations widely separated evolved at different rates. They slowly grew more different, but genes may change faster than the observable physical characteristics that mirror these changes. Further study of the various populations may reveal groups that merit species distinctions. It is possible that L. eximia is a species complex based on the CO1 data, but it is beyond the scope of the present work to sort this out.
