Cyclargus
Cyclargus is a genus of butterflies in the family Lycaenidae. It was split off from the genus Hemiargus in 1948 by Vladimir Nabokov, although many lepidopterists have not accepted the new genus as valid. Nabokov designated C. ammon as the type species for the genus, and included C. dominica, C. thomasi, C. woodruffi and C. erembis. In 1992 K. Johnston and Matusik described C. sorpresus and C. kathleena, both from Hispaniola.
The critically endangered Miami blue is a member of the genus.
C. a. erembis was described originally as a full species, as opinion is at present divided as to whether or not this might be its status.
