Anolis ginaelisae

Anolis ginaelisae

Six large anoles of the Dactyloa clade occur in western Panama. In their explorations, Lotzkat and colleagues have collected all of them, and have just published a paper in Zootaxa reviewing these species. Their phylogenetic analyses based both on DNA and morphological characters confirm the existence of the six taxa, but also find geographically-oriented genetic differentiation in two species. In combination with morphological data, the authors split A. microtus into two species, the new one under the name A. ginaelisae.

The paper includes a nice review of all the species including spiffy color plates (see A. ibanezi below as an example) and natural history notes (short take: they’re all arboreal and almost all individuals have been caught at night). A key is also included.

One last note. The derivation of the new specific epithet gianaelisae is touching: “Sebastian Lotzkat dedicates this exceptionally beautiful new species to his even more enchanting fiancée Gina Elisa Moog, who has made more than a third of his life worthwhile by now, in deepest gratitude for that wonderful time and pleasant anticipation of a mutual future.”

Abstract: “Six species of giant alpha anoles of the genus Dactyloa are known to occur in western Panama: Dactyloa casildae, D. frenata, D. ibanezi, D. insignis, D. kunayalae, and D. microtus. Based on own material collected along the highlands in Bocas del Toro, Chiriquí, and Veraguas provinces and the Comarca Ngöbe-Buglé of western Panama, we review their variation in morphological characters and the 16S rRNA mitochondrial gene. Our results support all six nominal taxa, but reveal considerable genetic differentiation between populations of the two highland species, D. casildae and D. microtus, respectively, from different localities. Correlated morphological differences confirm the existence of a cryptic species among populations currently assigned to D. microtus, which we describe as Dactyloa ginaelisae sp. nov. We provide point distribution maps, morphology and color descriptions, photographs in life, conservation status assessments, and an identification key for all seven species.”
