Diagnosis | DIAGNOSIS (andrewsi). Pliocercus andrewsi differs from all other species of the genus, except P. bicolor, in the combination of 5- 7 black rings on the body that are 50-125% of the length of the pale interspaces. Pliocercus bicolor rarely (1 in 55) has as few as 7 black rings on the body equally as long as those of P andrewsi, and differs also in having the posterior infralabial fused with the second labiogenial. In addition, P. andrewsi differs from the P. euryzonus complex (P. dimidiatus, P. euryzonus) in having tricolor rings. All other congeners have either more numerous black rings on the body or, if equally few, black rings that are much shorter than half the length of the pale interspaces [SMITH & CHISZAR 2001].

Comment | This genus / species complex is in urgent need of revision. While Smith & Chiszar 2001 (CAAR) have summarized the state of knowledge at the time, there seems to be no molecular analysis of the relationships among the numerous subspecies and synonyms. A bicolour (red and black) OR tricolour (red, yellow and black) banded or ringed form that mimics the pattern of sympatric species of venomous coral snakes (Micrurus sp.) Subspecies: Smith & Chiszar 2001 (CAAR 739) listed 5 subspecies: elapoides, aequalis, diastema, occidentalis, and wilmarai (the latter of which is now often considered a valid species). Mimicry: Pliocercus elapoides (and Pliocercus wilmarai, if recognized) mimicks Micrurus bernadi, M. tener, M. diastema, and M. limbatus (TORRE-LORANCA et al. 2006). Type species: Pliocercus elapoides COPE 1860: 253 is the type species of the genus Pliocercus COPE 1860. Synonymy: Pliocercus and Urotheca have been synonymized by Savage & Crother 1989. However, other disagree and have kept the two genera separate (e.g. Smith et al. 1995: 204). P. wilmarai is a synonym of Pliocercus elapoides fide WALLACH et al. 2014: 570 and Heimes 2016: 284. |
Etymology | The derivation of the specific name is from the Latin words elaps, meaning "snake or coralsnake" and oides, a suffix meaning "likeness," in reference to its similarity in color pattem to that of a coralsnake. The genus name Pliocercus is derived from the Greek words pleio, meaning "more" and kerkos, meaning "tail," in reference to the long and thick tail in members of this genus. The subspecies occidentalis ("of the west"), used here as an adjective, refers to the unique geographic occurrence of this subspecies. Pliocercus andrewsi honors the collector of the type specimens, E. Wyllys Andrews, who contributed extensively to the knowledge of the herpetofauna of the Yucatan Peninsula and to the collections of the Field Museum of Natural History. |
