Topotype material examined. INDIA: Kerala: Trivandrum: Ponmudi: way to Varayadumotta, 13 December 2014, M.S. Pradeep leg., from web on roadside mud embankment, by hand: 2 ♀♀, 1 subadult ♀, 1 juvenile (ADSH59501); Ponmudi (8°45'35.79''N, 77°7'00.75''E; 920 m alt.), 5 December 2019, M.S. Pradeep &A. V. Mathew leg., from web on roadside mud embankment, by hand: 4 ♀♀, 1 juvenile (ADSH59503). Other material examined. INDIA: Kerala: Palakkad: Parambikulam Tiger Reserve: Sunkam Range, 26August 2015, Jimmy Paul leg., from web on roadside mud embankment, by hand: 1 ♂, 2 ♀♀ (ADSH59502). INDIA: Tamil Nadu: Salem: Yercaud (11°46'N, 78°12'E; 1420 m alt.), 28 May 2019, M.S. Pradeep & A. V. Mathew leg., from web on roadside mud embankment, by hand: 3 ♀♀ (ADSH59504). Diagnosis. Males of H. pantherina are similar to the males of H. lingxianensis as both have very long anterior arm of tegular apophysis and a hook-like embolus, but can be distinguished from the latter by anteriorly oriented distal part of anterior arm of tegular apophysis (vs. retrolaterally oriented in H. lingxianensis) and broad conductor (vs. narrow in H. lingxianensis) (compare Figs 28A–D, 29A–C with Wang et al. 2015: fig. 5A–B). Females of H. pantherina are similar to the females of H. loundesi as both share spermathecal stalks with broad proximal and narrow distal parts, but can be separated from the latter by less developed median epigynal plate (vs. well-developed in H. loundesi), vulva with lateral pockets accommodating spermathecal stalks (vs. absent in H. loundesi) and oval spermathecae (vs. globular in H. loundesi) (compare Figs 28F, 29D–E with Figs 17E, 18A–B).
