Pseudobatos glaucostigmus ( Jordan & Gilbert, 1883) .

Speckled Guitarfish. To 91 cm TL (35.8 in) TL (Rodrigues-Romero et al. 2008); a much larger record, about 150 cm (59.1 in) TL ( Ramírez-Amaro et al. 2013) is undocumented. Bahía Magdalena, southern Baja California Sur (Pollom et al. 2000a) to Ecuador ( Amezcua Linares 1996), including Gulf of California (McEachran in Fischer et al. 1995). Benthic; depth: intertidal to 112 m (367 ft) (min.: Weigman 2016; max: Amezcua Linares 1996). In an analysis of DNA, Naylor et al. (2012) found no statistical difference between this species and Pseudobatos productus (Ayres, 1854) . Nevertheless, because of differences in morphology and color patterns, they retained the two species.
