Coalcomán (3); El Sabino (3); Uruapan (5).
The range of Leptodeira splendida bressoni apparently does not overlap that of Leptodeira maculata; the latter is restricted to the lower reaches of the arid scrub forest, whereas L. s. bressoni inhabits the upper limits of the arid scrub forest and the lower part of the pine-oak forest. Specimens have been collected between 950 and 1630 meters on the slopes of the Cordillera Volcánica and at 950 meters in the Sierra de Coalcomán. At Uruapan individuals were found beneath rocks along a stream and in a stone fence. Leptodeira duellmani, which was described from Coalcomán by Peters (1954:25), is an aberrant individual of L. s. bressoni (Duellman, 1958a:56).

Most specimens of this species have been collected in tropical semi-deciduous forest at elevations of less than 1000 meters. In the Sierra de Coalcomán one was taken in pine-oak forest at an elevation of 1700 meters near Ocorla; another was found in broad-leafed forest between Aguililla and Dos Aguas at an elevation of 1600 meters. Most individuals have been seen in trees or bushes. The absence of broad-leafed forest in the Tepalcatepec Valley probably accounts for the absence of this snake in that area.
