Type material. Catocala hippolyta: lectotype ♁ [FMNH, examined], designated by Gall and Hawks (1990: 10). Barnes and McDunnough (1918: 30) stated “the species is only known from the Coast Range of California extending from Sonoma County to Los Angeles County.” Although C. hippolyta has been treated as an endemic coastal Californian species, it in fact comes into contact with C. semirelicta Grote, 1874 along the eastern and northern edges of its geographic range in the Sierra Nevada mountains, where the two blend into one another. Moreover, during the past several decades, Paul and Sandy Russell have collected from one locality in the Santa Barbara foothills a series of C. hippolyta that contains specimens indistinguishable from typical C. semirelicta . We thus feel the observed geographic variation in C. hippolyta and C. semirelicta is more indicative of two subspecies. Type Locality: San Mateo County, California, [USA].
