Spariolenus tigris Simon. Pocock 1900: 264 View in CoL (in part, misidentification, record of one female from India: Pune, used as paratype here, see below); Sethi and Tikader 1988: 8 (in part, misidentification of the noted female).
Type material: Holotype: female, India: Karnataka: Uttanur , 16.18 N, 77.10 E, 391 m, 2010, Neha, Manju & Susaj leg. ( SMF) GoogleMaps . Paratypes: 1♀, India: Maharashtra: Pune [label: Spariolenus tigris Simon ; India: Poona Distr. R.C. Wroughton, Bombay Nat. Hist. Soc. ( NHM 1899.9.21.511)] ; 1♂, 1♀, India: Maharashtra: Western Ghats, Satara, Morghal cave , 17.63 N, 73.86 E, 800 m, Nov 2015, Kulkarni leg. ( BNHS) GoogleMaps .
Etymology. In the cultural history of Bharat ( India), Bakasura is the name of a voracious feeding demon who lived in caves, noun in apposition.
Diagnosis. The male resembles S. omidvarbrothers sp. n., S. zagros , S. fathpouri , and S. mansourii by bifurcated ET ( Figs 3A, C View FIGURES 3 ) but differ from them by stout and robust PET and RET (vs. slender and elongated ones in the other species). The remaining species with known males embody simple or not bifurcated ET [e.g., S. iranomaximus Moradmand & Jäger, 2011 ; S. tigris and S. buxa ( Saha et al. 1995) ]; Female is similar to S. tigris by having widened CO occupying majority of the EP (vs. not so in the rest of species) but it is distinguished from S. tigris by MEP extending beyond CO laterally (vice versa in S. tigris ) ( Fig. 4A View FIGURES 4 ).
Male (Paratype): Measurements. TL 13.5, 8.8, 7.9, 4.0, 9.5, PL 7.2, PW 6.3, AW 3.6, OL 6.3, OW 4.5. Eyes. AME 0.25, ALE 0.52, PME 0.3, PLE 0.50, eye inter distances: AME-AME 0.23, AME-ALE 0.13, PME-PME 0.28, PME-PLE 0.48, AME-PME 0. 38, ALE-PLE 0.47. clypeus-AME 1.02, clypeus-ALE 0.7. Spination. Palp 131, 101, 2121; Legs: Femur I–III 323(2), IV 321; Patella I–IV 000; Tibia I–II 111(10), III 1118, IV 2226; Metatarsus I–III 1014, IV 3036. Measurements of palp and legs. Palp 13.08 [4.2, 1.6, 2.56, 4.72], I 50.4 [12.8, 4.27, 14.4, 14.67, 4.27]; II 57.07 [14.67, 3.47, 16.53, 17.6, 4.8]; III 46.4 [12.27, 3.47, 13.33, 13.07, 4.27]; IV 42.4 [12,2.13, 12.27, 13.6, 2.4]. Chelicerae with 3 promarginal and 5 retromarginal teeth, cheliceral furrow with around 20 denticles.
Palp. As in diagnosis, with cymbium subequal to tibia in length, RTA short, BRB present, embolus longer than conductor, PET much shorter than RET ( Figs 3A–C View FIGURES 3 ).
Colouration. Same as for female ( Fig. 12A View FIGURE 12 ).
Female (holotype): Measurements. TL 18.3, PL 8.8, PW 7.9, AW 4.0, OL 9.5, OW 7.2. Eyes. AME 0.33, ALE 0.63, PME 0.46, PLE 0.61, AME-AME 0.23, AME-ALE 0.03, PME-PME 0.21, PME-PLE 0.51, AME-PME 0.41, ALE-PLE 0.58, clypeus-AME 0.65, clypeus-ALE 0.96. Chelicerae with 3 promarginal and 5 retromarginal teeth, and 20 intermarginal denticles. Measurements of palp and legs. Palp 14.1 [4.2, 2.1, 3.0, 4.8], I 48.4 [13.0, 4.3, 14.1, 13.3, 3.7], II 53.4 [15.2, 4.8, 14.7, 14.6, 4.1], III 45.7 [12.2, 4.1, 12.7, 13.1, 3.6], IV not available. Spination. Palp 131, 101, 2121, 1014; Legs (leg IV missing): Femur I 423, II–III 323; Patella I–III 101; Tibia I 405(10), II 404(10), III 3148; Metatarsus I–II 1014, III 2014.
Female copulatory organ. As in diagnosis, EF longer than wide, AB present and continuous to EF, CO widened longitudinally, MEP extended beyond EP laterally, MS not widened ( Fig. 4A View FIGURES 4 ); SC of vulva extending laterally beyond FC and TC in ventral view ( Fig. 4B View FIGURES 4 ).
Colouration. Generally beige in body with contrasting darker bands and spots on legs and stripes on carapace ( Figs 9D View FIGURES 9 , 12B View FIGURE 12 ).
Distribution and habitat preferences. This species seems to be widespread in the south and western Indian Peninsula ( Fig. 13 View FIGURE 13 ). Subadult male and female specimens were collected within the Morghal cave entrance corridor ( Fig. 12A–C View FIGURE 12 ) in the Western Ghats and then reared in captivity to get mature. Attached to the cave wall, a plastered old egg sac with exuviae of spiderlings instars was observed ( Fig. 12D View FIGURE 12 ) similar to the egg sac of Spariolenus arata documented by Moradmand & Jäger (2011: fig. 40), from Iran.
