Discussion: P. truei species group. Mexican populations revised, as part of P. truei, by Hoffmeister (1951). Divergent karyotypes and genetic distances had questioned unity of P. truei (Lee et al., 1972; Zimmerman et al., 1978); sympatry documented in New Mexico by Modi and Lee (1984), who raised P. gratus to a species (also see DeWalt et al., 1993 b; Janecek, 1990; Tiemann-Boege et al., 2000).
