Striaria zygoleuca Hoffman, 1950

Striaria zygoleuca Hoffman, 1950 , J. Elisha Mitchell Sci. Soc. 66: 16. Male holotype from Highlands, Macon Co., North Carolina (USNMNH). Causey, 1958, Proc. Biol. Soc. Washington 71: 181 (as a synonym of S. granulosa ) Hoffman, 1999, Virginia Mus. Nat. Hist. Special Publ. 8: 209. Hoffman (1999) states that this species occurs in “western North Carolina and eastern Tennessee ” but no specific additional localities are given. Following Causey (1958) he also thought that the species was a junior synonym of S. granulosa , but this may not be the case since an examination by WAS of the holotype’s gonopods showed them to be different from the illustrations of S. granulosa by Cook (1899). Striaria zygoleuca also has a striking white collum contrasting with the dark pigment of the rest of the trunk and such an obvious feature was not mentioned for S. granulosa by either Bollman (1888) or Cook (1899). Causey (1958) did not examine the specimens of S. granulosa described by Cook (1899) and had only juvenile specimens possibly attributable to S. zygoleuca . She gave no reasons for the synonymy. All of the Georgia, Kentucky and North Carolina localities listed by Causey under S. granulosa (some of which may be attributable to S. zygoleuca ) are based on juvenile specimens.
