Review of Bolivian Dipsas (Serpentes: Colubridae), with Comments on Other South American Species

Review of Bolivian Dipsas (Serpentes: Colubridae), with Comments on Other South American Species Seven species of Dipsas occur within Bolivia. On the basis of new material, we revise D. chaparensis , D. peruana , and D. variegata . We review D. i. cisticeps and consider it to be a subspecies of D. bucephala . We transfer D. boettgeri , D. latifrontalis , and D. polylepis to the synonymy of D. peruana . We consider D. neivai and populations of D. variegata from Bolivia, Brazil, and Peru to be conspecific with Guianan and Venezuelan D. variegata . On the other hand, we recognize D. trinitatis Parker as a morphologically distinct, full species rather than a subspecies of D. variegata . We refer Leptognathus robusta Müller to the synonymy of D. oreas rather than D. variegata . Alizarin red staining reveals calcification patterns of snake hemipenes and is recommended as a modification of techniques used to prepare these organs. Characters of visceral morphology improve our understanding of dipsadine relationships. As in most snakes, male Dipsas usually have higher subcaudal counts than females. On the other hand, species of Dipsas either have reverse ventral count dimorphism or their ventral counts are not dimorphic. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Herpetological Monographs Allen Press

Abstract

Seven species of Dipsas occur within Bolivia. On the basis of new material, we revise D. chaparensis , D. peruana , and D. variegata . We review D. i. cisticeps and consider it to be a subspecies of D. bucephala . We transfer D. boettgeri , D. latifrontalis , and D. polylepis to the synonymy of D. peruana . We consider D. neivai and populations of D. variegata from Bolivia, Brazil, and Peru to be conspecific with Guianan and Venezuelan D. variegata . On the other hand, we recognize D. trinitatis Parker as a morphologically distinct, full species rather than a subspecies of D. variegata . We refer Leptognathus robusta Müller to the synonymy of D. oreas rather than D. variegata . Alizarin red staining reveals calcification patterns of snake hemipenes and is recommended as a modification of techniques used to prepare these organs. Characters of visceral morphology improve our understanding of dipsadine relationships. As in most snakes, male Dipsas usually have higher subcaudal counts than females. On the other hand, species of Dipsas either have reverse ventral count dimorphism or their ventral counts are not dimorphic.
