Diagnosis

The male of H. sahyadri sp. nov. is very similar to H. liptoni Kanesharatnam & Benjamin, 2020 and can be distinguished by the narrow embolus directed at 1 o’clock position (vs broad, flattened and directed at 11 o’clock position), well developed posterior rounded bulbal process (vs irregular) and RTA with broad base, triangular (vs RTA narrow) (cf. Figs 26–27 View Figs 24–27 , 32–33 View Figs 32–35 ; Kanesharatnam & Benjamin 2020: figs 1d, 3a, 1c–e, 3a–b). The female of H. sahyadri is very similar to that of H. dubium Wesołowska & van Harten, 2002 , but can be distinguished by the placement of the copulatory openings, placed mid-laterally (vs placed posteriorly), copulatory duct wide (vs narrow) (cf. Figs30–31 View Figs 28–31 , 34–35 View Figs 32–35 ; Wesołowska & van Harten 2002: figs 11–13).

Etymology

The specific epithet refers to the Sanskrit word for the Western Ghats, from where the species was collected.
