|Scientific name||Lampropeltis abnorma (BOCOURT, 1886)|
|English name||Central American Milk Snake|
|Habitat||L. abnorma “hondurensis-phase” occurs in all habitats that are present in the lowland and on moderate hights.
L. abnorma “stuarti -phase” occurs in dry, tropical forests and on the plains along the coast.
L. abnorma “abnorma-phase” lives mainly in densely populated forests, where it often is found under rotting wood and other material on the forest floor.
From the other two “phases” I did not find information about the habitat.
|Distribution||South-eastern Guerrero and southern Veracruz (Mexico) and then southwards in Nicaragua, Honduras and western Costa Rica.
It may also occur in southern Oaxaca and probably in Campeche, Chiapas, Quintana Roo, Yucatan (Mexico) and in Belize and El Salvador.
|Before 2014, this species did not actually exist.
In that year, major revisions were made regarding species and subspecies of Lampropeltis, among others based on DNA research. If you want to know more about this, read this article…
Ruane, Sara; Robert W. Bryson, Jr., R. Alexander Pyron, and Frank T. Burbrink 2014. Coalescent Species Delimitation in Milksnakes (genus Lampropeltis) and Impacts on Phylogenetic Comparative Analyses. Systematic Biology 63 (2): 231-250
Simply put, in 2014 L. abnorma is “composed” of the following species/subspecies:
Lampropeltis triangulum abnorma (Guatemala)
Lampropeltis triangulum hondurensis (northern Honduras, Nicaragua en north-eastern Costa Rica)
Lampropeltis triangulum oligozona (Oaxaca, Chiapas – Mexico, Esquintla – Guatemala)
Lampropeltis triangulum stuarti (El Salvador, Honduras, Nicaragua, north-western Costa Rica).
The expectation is that, most probably, the old scientific names will still be used regularly.
Or, for example, something like L. abnorma “hondurensis” or L. abnorma (hondurensis-phase).
