Abstract
Las poblaciones de toboba de pestañas o bocaracá del suroeste de Costa Rica han sido denominadas tradicionalmente Bothriechis schlegelii supraciliaris Taylor 1954. Sin embargo, la morfometría y el patrón de coloración sugieren que es una especie aparte, que aquí se propone como Bothriechis supraciliaris stat.nov.
Highlights
It is closely related to B. schlegelii from which it differs by íts color patterns based on a uniforrn ground color with polymorphic dorsal designs, and its lower counts of ventral and caudal scales
Taylor described a specimen from Valle del General (San José province, South West Costa Rica), as a subspecies of Bothrops schlegelii (Berthold), which he named Bothrops schlegelii supraciliaris
Fifty-seven specimens of typical Bothriechis schlegelii, from various parts of Costa Rica and twenty-five specimens collected in the forest reserve of the Las Cruces Biological Station, Coto Brus, Puntarenas, at 1000-1400 m a.s.l., were compared for scale counts and for color pattems of live specimens
Summary
H. Taylor described one specimen from the area as a new subspecies, B. schlegelii supraciliaris. It is closely related to B. schlegelii from which it differs by íts color patterns based on a uniforrn ground color with polymorphic dorsal designs, and its lower counts of ventral and caudal scales.
