A new species of the genus Siler Simon, 1889 (Araneae, Salticidae, Chrysillini) from India

A new chrysilline jumping spider species belonging to the genus Siler Simon, 1889 is described from Odisha, India. Detailed mor-phological descriptions, illustrations of the male palp and female genitalia and phylogenetic relationships of the new Siler species are presented. Phylogenetic analysis reveals that the new species is sister to a clade of predominantly Southeast Asian Siler species. Furthermore, the results indicate the presence of multiple cryptic species masquerading as S. semiglaucus sensu lato. We also briefly discuss some unique behavioural observations on the newly-described species.
