Micrurus ibiboboca (Serpentes, Elapidae) is not a Guiana Shield Species
( ) Coral snakes (Micrurus) are a diverse group of Neotropical squamates. Similarities in morphology and coloration can make identification difficult, especially in areas of species sympatry. Species with triad-type coloration, approximately 30% of all Micrurus species, are among the most difficult to identify. Micrurus ibiboboca Merrem, 1820 is an east Brazilian species with triad-type colorat...
متن کاملA new species of monadal coral snake of the genus Micrurus (Serpentes, Elapidae) from western Amazon.
We described a new species of monadal coral snake of the genus Micrurus from the region of Tabatinga and Leticia, along the boundaries of Brazil, Colombia, and Peru. The new species can be distinguished from the other congeners by the combination of the following characters: absence of a pale nuchal collar; black cephalic-cap extending from rostral to firstdorsal scale and enclosing white tippe...
متن کاملNeuromuscular Activity of Micrurus laticollaris (Squamata: Elapidae) Venom in Vitro
In this work, we have examined the neuromuscular activity of Micrurus laticollaris (Mexican coral snake) venom (MLV) in vertebrate isolated nerve-muscle preparations. In chick biventer cervicis preparations, the MLV induced an irreversible concentration- and time-dependent (1-30 µg/mL) neuromuscular blockade, with 50% blockade occurring between 8 and 30 min. Muscle contractures evoked by exogen...
متن کاملHerpetologists' League Phylogeny of South American Triad Coral Snakes (Elapidae: Micrurus) Based on Molecular Characters
We present new molecular data (mtDNA sequences and allozymes) for several species of Souith American "triad" coral snakes. We present a phylogenetic hypothesis for the group based on analysis of molecular characters using both maximum parsimony (MP) and maximu-m likelihood (ML) optimality criteria. Results from both methods are generally congruent and suggest a basal position for the morphologi...
متن کاملThe Development of the Skull of the Egyptian Cobra Naja h. haje (Squamata: Serpentes: Elapidae)
BACKGROUND The study of craniofacial development is important in understanding the ontogenetic processes behind morphological diversity. A complete morphological description of the embryonic skull development of the Egyptian cobra, Naja h. haje, is lacking and there has been little comparative discussion of skull development either among elapid snakes or between them and other snakes. METHODO...
