This species is known only from the Tepalcatepec Valley, where it has been found in open arid situations from 180 to 500 meters. Specimens were found in the daytime in stumps, dead cacti, and the hollow branches of the legume, _Apoplanesia paniculata_. In life adults were pale gray or grayish tan above and creamy white below. A juvenile having a snout-vent length of 18 mm. had a pale orange tail with gray cross-bands. In the adults the tail was colored like the body. The specimen from 14 kilometers south-southwest of Apatzingán (KU 29764) and those from Cofradía (BMNH 1914.1.28.28-30) were not listed by Dixon (1960). ~Phyllodactylus homolepidurus~ Smith _Phyllodactylus homolepidurus_ Smith, Univ. Kansas Sci. Bull., 22:121, November 15, 1935.--Five miles southwest of Hermosillo, Sonora, México. El Ticuiz (2); La Placita; Ostula (2); Pómaro; San Pedro Naranjestila. These specimens have been referred to _Phyllodactylus homolepidurus_ by James R. Dixon (_in litt._), who is currently studying the American members of the genus. Geckos of this species have been found in tropical semi-deciduous forest in the coastal lowlands to elevations of 500 meters. Most specimens were found beneath the bark of standing dead trees or stumps. Two individuals from El Ticuiz (UMMZ 115102) in life were dark gray above with brownish tubercles; the belly was a dusty cream-color. Apparently this species does not enter the Tepalcatepec Valley, where _Phyllodactylus lanei_ is abundant. ~Phyllodactylus lanei~ Smith _Phyllodactylus lanei_ Smith, Univ. Kansas Sci. Bull., 22:125, November 15, 1935.--Tierra Colorado, Guerrero, México. Apatzingán (13); 21 km. S of Arteaga: El Sabino (53); La Playa; Ostula (2); Río Marquez, 10 km. S of Lombardia (8); 16 km. N of Tafetán. This widespread species has been taken at elevations of less than 1100 meters in the Balsas-Tepalcatepec Basin, where it occurs in riparian situations in the foothills. Specimens have been collected in tropical semi-deciduous forest at Ostula and in oak forest south of Arteaga; both of these localities are on the Pacific slopes of the Sierra de Coalcomán, a region inhabited by _Phyllodactylus homolepidurus_. Both species have been collected at Ostula. A juvenile from 21 kilometers south of Arteaga (UMMZ 118933) had alternating black and white bands on the tail. In life most of the lizards are dull ashy gray or grayish tan above and white below. According to Dixon (_in litt._), one specimen from Apatzingán (UMMZ 115102) resembles _Phyllodactylus magnus_ in scutellation, but it lacks the distinctive yellow venter of that species. Apparently _Phyllodactylus lanei_ is restricted to rather mesic environments in the Balsas-Tepalcatepec Valley and surrounding foothills; in the more open arid environments on the floor of the valley it seems to be replaced by _Phyllodactylus duellmani_. ~Phyllodactylus paucituberculatus~ Dixon
