On the phylogenetic position of the genus Birulatus Vachon, 1973 (Scorpiones, Buthidae) and redescription of Birulatus haasi

Abstract

The phylogenetic position of the genus Birulatus Vachon, 1973 is revised. VACHON (1973) did not express any precise opinion about the phylogenetic position of the new genus. The present analysis shows that the genus Birulatus can be associated to some extent with genera such as Compsobuthus Vachon, Cicileus Vachon and Buthiscus Birula, but it undoubtedly represents an older lineage, and stands in an isolated phylogenetic position. Birulatus should therefore, be classified among the incertae sedis genera within the family Buthidae.

Kurzfassung

Die phylogenetische Position der Skorpionsgattung Birulatus Vachon, 1973 wird revidiert. VACHON (1973) hatte keine präzise Meinung über die phylogenetischen Beziehungen der Gattung mitgeteilt. Die hier vorgenommene Analyse zeigt, daß die Gattung in einem gewissen Grade mit den Gattungen Compsobuthus Vachon, Cicileus Vachon and Buthiscus Birula in verwandschaftlicher Beziehung steht, daß sie aber zeifelsohne einer älteren Abstammungslinie angehört, und phylogenetisch isoliert dasteht. Birulatus sollte daher innerhalb der Familie der Buthidae als incertae sedis-Gattung eingestuft werden.
