November, 1961 Smith: Amphibians and Reptiles of Illinois 47 Eurycea longicauda melanopleura (Cope) Dark-Sided Salamander Spelerpes melanopleurus Cope 1893Z':383 (type locality: Raley's Creek, White River, Mis- souri). Eurycea longicauda pernix X E. I. melano- pleura, Mittleman 19+2:104. Eurycea longicauda melanopleura, Grimmer & Langebartel 1948:224. Diagnosis.—A medium-sized, long-tailed salamander (largest Illinois specimen 130 mm. in total length), fig. 35, related to the subspecies longicauda but differing in having a longitudinal dark band (rather than a se- ries of vertical bars) on each side of the tail, numerous middorsal dark spots scat- tered or arranged in several irregular rows, numerous dark flecks on venter, vellow- green to yellow-brown groundcolor, and larger eyes. Variation.—The males of the dark-sided salamander differ externally from the fe- males in having more swollen snouts and larger nasolabial protuberances, but so many intermediate examples occur that dissection is often the only method by which the sex of an individual can be accurately deter- mined. In this subspecies subadults differ from older specimens less markedly than in Eury- cea longicauda longicauda but in similar characters. Seven specimens, 88 to 114 mm. in total length, have tail lengths to (average ) per cent of the total length, and six specimens, 115 to 130 mm. in total length, have tail lengths to (av- erage ) per cent. The groundcolor is us- ually more yellowish in small individuals. :*^W. ^" ^Wftfj Fig. 35.—An adult Eurycea longicauda melanopleura from Adams County, Illinois.
