Hippasa lycosina Pocock, 1900: 250 (♀). Gravely 1924: 593, fig. 1B (♀)

Hippasa mahabaleshwarensis Tikader & Malhotra, 1980: 285 , figs 85–89 (♂ ♀), synonymised by Song (1987) (for complete list of references, see World Spider Catalog 2022).

Type material. H. lycosina . Syntypes 2 ♀♀ from INDIA: Maharashtra: Nashik (=Nasik) (20°04'N, 73°36'E; 625 m alt.), date unknown, Millet leg., repository NHM (1899), not examined (illustrations of this species given in Tikader & Malhotra (1980: figs 91–92), who studied the types are diagnostic and were used for comparative purpose). H. mahabaleshwarensis . Holotype ♀ from INDIA: Maharashtra: Satara: Mahabaleshwar (17°56'N, 73°31'E; 151 m alt.); 26 March 1976, B.K. Tikader leg., repository NZC-ZSI (4651/18), examined . Paratypes 3 ♀♀ and allotypes 2 ♂♂, with the same data as holotype, examined .

Other material examined. INDIA: Karnataka: Chikmagalur: Mullayanagiri Peak (13°23'N, 75°43'E; 1894 m alt.), 18 February 2014, M.S. Pradeep leg., from web on ground, by hand: 1 ♂, 1 ♀ ( ADSH595026 ) .

Diagnosis. Males of H. lycosina are most similar to the males of H. albopunctata Thorell, 1899 as both share a short anterior arm of tegular apophysis and ventrally visible subtegulum, but can be separated from the latter by anterior arm of tegular apophysis with prolaterally oriented tip (vs. posteriorly in H. albopunctata ), and broad mesal arm of tegular apophysis with rounded tip (vs. narrow, thorn-like in H. albopunctata , compare Figs 19F–G , 21A–B with Alderweireldt & Jocqué 2005: fig. 14). Females are similar to the females of H. himalayensis as both share a large epigynal atrium, but can be separated from the latter by a widely triangular epigynal atrium (vs. narrowly triangular in H. himalayensis ), and spherical spermathecae (vs. peanut-shaped in H. himalayensis , compare Figs 20F–G , 21D–E with Fig. 14C–D ).

Distribution. China, Laos and India: Himachal Pradesh, Karnataka, Maharashtra, Tamil Nadu, Uttarakhand ( Pocock 1900; Gravely 1924; Tikader & Malhotra 1980; Yin & Wang 1980; Hu 1984; Chen & Gao 1990; Jäger & Praxaysombath 2011; Wang et al. 2015; Ahmed et al. 2015; Marusik & Nadolny 2021; present data) ( Fig. 39 ).

Remarks. We examined the types of Hippasa mahabaleshwarensis Tikader & Malhotra, 1980 and confirmed its synonymy with H. lycosina as proposed by Song (1987, compare Figs 19F–G , 21A–B with Fig. 22B–C ).
