Description DIAGNOSIS: Cryptobatrachus pedroruizi has thin dorsolateral folds and granular skin on the back with scattered large warts. The fingers of C. pedroruizi lack webbing but have subarticular adhesive pads and expanded disks on the digits. The anterior portion of the braincase and frontoparietals are narrow in C. pedroruizi in contrast to the widened anterior frontoparietals and braincase of C. boulengeri (Lynch 2008). All Cryptobatrachus species are very similar in appearance and are best distinguished by geographic location. COLORATION: The coloration of the back of C. pedroruizi (in preservative) is brown with a pale pre-sacral spot and dark brown blotches, and the limbs are pale brown with dark brown bands. The chin of C. pedroruizi is mottled with brown or gray and the belly is cream colored. The underside of the thigh is spotted with brown (Lynch 2008). VARIATION: This species exhibits a sexual dimorphism in the size of the tympanum: in males, the tympanum is ~65% of the eye and in females the tympanum is ~45% of the eye (Lynch 2008). Distribution and Habitat Country distribution from AmphibiaWeb's database: Colombia
Life History, Abundance, Activity, and Special Behaviors Females carry developing embryos directly on the back that hatch into miniature versions of the adult (no brooding pouch as in the hemiphractid genera Gastrotheca, Flectonotus, Fritziana). A photo of a female carrying recently hatched froglets is provided in Fig. 5 of Meza-Joya et al. (2021). The clutch size of Cryptobatrachus pedroruizi ranges from 16 - 45 offspring (Meza-Joya et al. 2021). No diet information is known. During a short survey in Vereda Puerto Rico, municipality El Molino, Guajira Department, Colombia in 2012, the species was common with 54 adults observed in four person-hours, but this population is now suspected to be decreasing (IUCN 2020). Larva Trends and Threats Possible reasons for amphibian decline General habitat alteration and loss Comments PHYLOGENETIC RELATIONSHIPS: Cryptobatrachus remotus is a junior synonym of C. pedroruizi (Meza-Joya et al. 2021). A maximum likelihood16S gene tree generated using IQ-TREE indicates that C. pedroruizi is sister to C. boulengeri and that this clade is sister to C. fuhrmanni (Meza-Joya et al. 2021). However, no molecular data is currently available for the remaining two Cryptobatrachus species: C. conditus and C. ruthveni.ETYMOLOGY: Cryptobatrachus pedroruizi was named in honor of Colombian herpetologist, Pedro Miguel Ruiz Carranza (Lynch 2008).
