Two new species of Bonnetina tarantulas (Theraphosidae: Theraphosinae) from Mexico: contributions to morphological nomenclature and molecular characterization of types
David Ortiz, Oscar F. Francke
Two new species of tarantulas from Mexico are described and illustrated: Bonnetina tenuiverpis and Bonnetina juxtantricola, from the states of Mexico and Guerrero, respectively. Male palpal bulbs, tibial apophyses and spermatheca are among the most taxonomically informative characters. Male bulb microstructure is revealed from scanning electron microscopy; both new and homologous structures to other Theraphosinae genera are identified and described. Nomenclatural changes for male tibial apophyses are also proposed. The holotype male and allotype female of one of the species are molecularly characterized and matched from CO1 partial sequence.
About the Author
My main research interests are evolutionary biology of mygalomorph spiders (tarantulas and their kin) and the trace that history has left in their genome, morphology, ecological niche, etc. I am working on my PhD project of phylogenetic systematics of the tarantula genus Bonnetina (Theraphosidae), using molecular and morphological evidence. I am also working on Bonnetina as model to determine species boundaries in an integrative approach.
