This species was synonymized with Lucilia cluvia by Aubertin 
(1933) ; it was not treated by Shannon (1926) in his synopsis of 
American Calliphoridae. It is colored very differently from any 
known North American species. In fact, its particular type of 
coloring is approached only by Lucia graphita Shannon, 
described from the Hawaiian Islands, which is almost entirely 
black. 
Johnson described the holotype of problematica as being a male 
specimen collected in Bermuda on June 30, 1905, by Professor 
Kineaid. This specimen is now in the National Museum collection 
. erroneously marked ‘‘Cotype.’’
