We investigated the evolutionary and biogeographic history of Himalayan and Hindu Kush Gloydius pitvipers by integrating time‐calibrated phylogenetic analyses with paleoclimatic reconstructions and species distribution modeling. Our results suggest an early Miocene origin in East and Southeast Asia, followed by westward dispersal across Paleo‐Tibet via

In all snakes, the Boidae and Xenopeltidae excepted, only the right lung is well developed, while the left lung is rudimentary or absent (BUTLER, 1895). The right lung consists of an anterior alveolar part that is strongly vascularized, and of a posterior smooth-walled air-sac that is anangious.

Endoparasites of Crotalus tzabcan (Serpentes: Viperidae), with a checklist in rattlesnakes [PDF]
The helminth and pentastomid fauna of 50 specimens of Crotalus tzabcan from the Yucatán Peninsula, Mexico is documented. The examination revealed the presence of three nematode species (Hastospiculum onchocercum, Hexametra boddaertii, and Travassosascaris araujoi), and one pentastomid (Porocephalus crotali).
