Anolis Tropidogaster Sundered

Squares are A. gaigei; circles are A. tropidogaster; triangles are locations of members of the species complex for which specimens were not examined and thus determination to species has not yet been accomplished.

Gunther Köhler’s at it again! This time with a merry band of colleagues he’s split Anolis tropidogaster, a little brownjob of an anole widespread in southern Central America and Colombia, into two species, A. tropidogaster in Colombia and eastern Panama and A. gaigei sandwiching it in western panama and the Santa Clara Mountains of Colombia.

Like a number of recently differentiated mainland anoles, the species differ markedly in the shape of their hemipenes. However, in contrast to some other cases, they also differ in dewlap color and a number of scale characters. Further, a limited genetic analysis suggests that the two forms may be substantially differentiated genetically.

Professor and Curator of Herpetology at the Museum of Comparative Zoology at Harvard University. I've spent my entire professional career studying anoles and have discovered that the more I learn about anoles, the more I realize I don't know.

One thought on “Anolis Tropidogaster Sundered

  1. Nice job, excellent web page, just a little comment, I think you meant Santa Marta Mountains of Colombia instead of Santa Clara.

    Cheers,

    Laury from Colombia, of course
