Most specimens were found beneath rocks in grassy areas near the upper limits of the arid scrub forest, both in the Sierra de Coalcomán and on the southern slopes of the Cordillera Volcánica; all are from elevations of less than 1100 meters. One specimen was found on a road at night near Apatzingán. This species has been found in similar habitats near Huajintlán, Guerrero, and in arid scrub forest at lower elevations in Colima. It is unknown from the coast of Michoacán.

Apatzingán.
This specimen (CNHM 39208) was reported by Schmidt and Shannon (1947:81); they stated that it was a paratype of P. pulcherrima. However, Taylor and Smith (1942a:246) did not mention the specimen; aside from the type (EHT-HMS 5497), the only other specimen they designated as belonging to the type series was UMMZ 85711 from Chilpancingo, Guerrero.
The taxonomic validity of Pseudoficimia pulcherrima remains doubtful, for only minor characters distinguish it from P. frontalis. Furthermore, all known specimens of P. pulcherrima are from within the geographic range of P. frontalis.
