Taxonomic change of two species in the genus Haploclastus Simon 1892 (Araneae, Theraphosidae)

Abstract

The genus Haploclastus is represented by eight species in India. In this paper, we synonymise Haploclastus robustus Pocock, 1900 with H. validus Pocock, 1899. H. himalayensis Tikader, 1977 is transferred to the genus Chilobrachys based on a generic character, the presence of enlarged paddle setae on prolateral side of maxillae. We provide additional information on morphometry and photographs of the palp and stridulatory setae that are lacking in the original description.
