Data from: A taxonomic revision of the North American species of Lepraria s.l. that produce divaricatic acid, with notes on the type species of the genus L. incana.

James C. Lendemer
The divaricatic acid-producing populations of Lepraria in North America north of Mexico are revised using traditional morphological characters, chemistry, ecology, biogeography, and ITS1, 5.8S, and ITS2 sequence data. Three taxa are accepted: L. cryophila, L. hodkinsoniana sp. nov., and L. pacifica sp. nov. Both Lepraria crassissima and L. incana are excluded from the study area. Non-cryptic, semi-cryptic, and fully-cryptic species concepts in Lepraria are discussed with a special emphasis on the practical integration of molecular...

Data from: Understanding the formation of ancient intertropical disjunct distributions using Asian and Neotropical hinged-teeth snakes (Sibynophis and Scaphiodontophis: Serpentes: Colubridae)

Numerous taxa show ancient intertropical disjunct distributions. Many can be explained by well-known processes of historical vicariance, such as the breakup of Gondwanaland. Others, such as Asian–Neotropical divergences are not as well understood. To clarify the phylogenetic position and understand biogeographic and temporal origins the geographically disjunct and morphologically unique genera of hinged-teeth snakes, Scaphiodontophis (n = 1) and Sibynophis (n = 9; Colubridae), we inferred a time-calibrated phylogeny with additional 107 taxa representing the...
