|Diagnosis||Diagnosis. Synophis bogerti can be distinguished from other species of Synophis by having a semicapitate, bilobed hemipenis with a large lateral spine at the base of the hemipenial body (Fig. 3); 19 longitudinal rows of dorsals at midbody; strongly keeled dorsals except for first row, which is weakly keeled (at least posteriorly); and 154–163 ventrals in males, 161–168 in females. Scutellational characters of all recognized species of Synophis are presented in Table 3.|
|Comment||Similar species: S. bicolor; the specimen (UMMZ 91550) illustrated by Bogert (1964) as S. bicolor is actually S. bogerti, as defined by TORRES-CARVAJAL et al. 2015. Specimens of “S. bicolor” from eastern Ecuador examined by Bogert (1964) correspond to S. bogerti.|
|Etymology||The specific epithet bogerti is a noun in the genitive case and is a patronym for Charles M. Bogert (1908–1992), an American herpetologist and former curator of the American Museum of Natural History. Among his many contributions, Bogert published a systematic revision of Diaphorolepis and Synophis, in which he rec- ognized that “It is also possible, of course, that specimens tentatively referred to S. bicolor are not actually conspecific” (Bogert 1964: 517).|
Some dictionaries called this species “Bogert’s fishing snakes” but there is no evidence this species eats fish (Pyron e al. 2016).
