Diagnosis. Males of Hersilia orvakalensis sp. nov. can be distinguished from all other described congeners (including H. tibialis) by the absence of crenulae on the retrolateral border of the median apophysis and by the short truncated distal area of the cymbium (Figs 9 – 14). Females can be distinguished by the shape of the spermathecae and accessory glands, which form a single elongate tri-lobed and pod-shaped structure, and by the shape of the median epigynal plate, which is extended posteriorly with a broad base (Figs 23 – 24). Both sexes are also characterized by the presence of two humps laterally on the abdomen (Figs 5, 17).
Etymology. The specific epithet is a noun in apposition, taken from the type locality at Orvakal Village, Kurnool District. Affinities. In the classification of Baehr and Baehr (1993) Hersilia orvakalensis sp. nov. would be placed in the H. pectinata species group. This group includes three other species from the Oriental Region and four species from the Afrotropical Region. Males are characterized by a pronounced angular dorsal projection on the pedipalpal tibia with four-seven strong spines, by lamellar modifications on the bulb of the male pedipalp, by a complex median apophysis and by a long, ridged embolus. Females are characterized by a median epigynal plate with basal rippled pads. Hersilia orvakalensis seems otherwise closely related to H. tibialis from India and Sri Lanka in possessing a relatively short male pedipalp, with a short and wide tibia bearing a conspicuous ridge and five strong spines. Like H. tibialis, the cymbium is also stout and markedly pilose, rounded off at the apex, with numerous short spines; the embolus is curved and free, with an enlarged apex; the retrolateral projection of the median apophysis is flat and broad; and the epigynum is large, consisting of a median plate with distinct lateral borders and an extended base.
