Diagnosis: O. gephyra can be distinguished from other species of Oedipina in Honduras by the presence of 17 or 18 costal grooves. Oedipina elongata is the exception. O. gephyra is distinguishable from O. elongata by the presence of maxillary teeth which O. elongata does not have. O. gephyra has a dorsum that is uniformly blackish-brown, while Oedipina elongata has a brown dorsum with lighter brown spots or patches on the head and on the body (McCranie et al. 1993; McCranie and Wilson 2002).
Coloration: O. gephyra is uniformly blackish-brown throughout, and the tail is black. Tiny iridophores are visible under magnification (McCranie et al., 1993).
Variation: Males have mental glands and premaxillary teeth that pierce the lip. In females, the premaxillary teeth are located behind the lip. Males have cloacal papillae, while females have shallow cloacal folds (McCranie and Wilson 2002).

The species name, gephyra, is derived from Greek root word that means “bridge.” The name refers to the fact that O. gephyra has several morphological features that bridge the gap between the species groups Oedipina uniformis and Oedipina parvipes . This was recognized by Brame when he revised the genus Oedipina in 1968 (McCranie et al. 1993; McCranie and Wilson, 2002).
The sister species of O. gephyra are Oedipina elongata and Oedipina carablanca (McCranie et al. 2008).
