Phylogenetic systematics of Pseudolebinthus, a new genus of Eneopterinae crickets (Orthoptera, Grylloidea, Eneopteridae) from south-east Africa

Abstract.  Within a framework of historical analysis of Eneopterinae crickets, the genus Pseudolebinthus Robillard gen.n. and two new species P. africanus Robillard, sp.n. and P. whellani Robillard, sp.n. , endemic from south-east Africa, are described. A cladistic analysis using 198 morphological characters and 47 terminals assessed the phylogenetic position of the new taxa within the subfamily. The resultant topologies support the previously proposed phylogeny for the subfamily and contained tribes. The monophyly of Pseudolebinthus is supported strongly as well as its sister relationship with Xenogryllus within the tribe Xenogryllini. A key to Eneopterinae tribes, Xenogryllini genera and Pseudolebinthus species is given. Taxonomic, evolutionary and acoustic issues raised by the recognition of Pseudolebinthus are discussed.
