The Amphibians and Reptiles of Michoacán, México

by William Edward Duellman

Coleonyx elegans nemoralis Klauber

Coleonyx elegans nemoralis Klauber, Trans. San Diego Soc. Nat. Hist., 10:195, March 9, 1949.—Paso del Río, Colima, México.

Klauber (1945:199) and Smith and Taylor (1950b:43) reported this lizard from the coastal lowlands of Colima and Guerrero. Davis and Smith (1953:101) reported it from 8 kilometers northeast of Temilpa, Morelos, in the upper Balsas Basin. Specimens of this lizard have been collected infrequently; the few locality records and limited ecological data indicate that it inhabits dense scrub forest and tropical semi-deciduous forest. Coleonyx elegans nemoralis is to be expected on the coastal lowlands, the seaward foothills of the Sierra de Coalcomán, and on the lower slopes of the Cordillera Volcánica along the northern edge of the Tepalcatepec Valley.

Phrynosoma orbiculare orbiculare (Linnaeus)

Lacerta obricularis Linnaeus, Systema naturae, ed. 12, 1:1062, 1789.—México (by inference). Type locality restricted to México, Districto Federal, by Smith and Taylor (1950b:97).

Phrynosoma orbiculare orbiculare, Smith, Trans. Kansas Acad. Sci., 37:290, 1934.

Gadow (1905:213) inferred that Phrynosoma orbiculare occurred at elevations of more than 3000 feet in Michoacán. There are no specimens of this species known from Gadow's collections made in Michoacán. Smith and Taylor (1950b:98) apparently accepted Gadow's statement and recorded the species from Michoacán: "above 3000 feet (Jorullo?)." Reeve (1952:940) somehow misconstrued this statement to read "Jorullo, above Zumpango (Smith and Taylor, 1950b)." Reeve did not indicate on his map (1952:939) that the species occurred in Michoacán. In the most recent review of the species (Horowitz, 1955), no localities are given in Michoacán. Since Phrynosoma orbiculare is known from central Jalisco, Guanajuato, Queretaro, and México, its presence at least in northeastern Michoacán is to be expected, although at the present time there are no specimens known from the state.

Eumeces brevirostris (Günther)
