Ciclos reproductivos de la serpiente coral Micrurus nigrocinctus (Serpentes: Elapidae) en Costa Rica

Abstract

The coral snake Micrurus nigrocinctus has two reproductive patterns in Costa Rica. Specimens of the Pacific population (M. n. nigrocinctus) mate during the early dry season (November, January). Oviposition takes place in February and March; the mean number of eggs was 7.9 (5-14) in this population. Births occur between April and June after 47-81 days of incubation. The total length of neonates is 168-212 mm, and the weight is 1.2-2.0 g. Specimens of the Atlantic population (M. n. mosquitensis) seem to have an extended breeding season. Oviposition in this subspecies was observed in March and June; the mean number of eggs was 6.7 (5-8). Births take place in May and August, after two months of incubation. Neonates have 173189 mm in total length and 1.9-2.4 g in mass. Adult females are longer than males, especially in M. n. mosquitensis.

En Costa Rica existen 2 poblaciones o subespecies: Micrurus nigrocinctus mosquitensis y M. nigrocinctus nigrocinctus, ubicadas en las vertientes Atlántica y Pacífica, respectivamente (Taylor et al. 1974) y separadas geográficamente por las Cadenas Montañosas. No existen datos sobre la actividad reproductiva de esta especie en el medio natural, ni sobre las características de los neonatos. En general, datos reproductivos sobre las especies de Micrurus en el Continente son escasos en la literatura. Este trabajo informa sobre los ciclos reproductivos de estas dos poblaciones de M. nigrocinctus en Costa Rica, los cuales muestran una clara variación en su periodicidad, así como de algunos parámetros demográficos.
