Arctosa lesserti Reimoser, 1934: 470 View in CoL , figs 2–3.

Arctosa mulani View in CoL — Tikader & Malhotra 1980: 373, figs 247–251 (neotype designation; transfer from Pardosa View in CoL ; misidentification). Majumder 2005: 26 (misidentification). Lu et al. 2016: 130, figs 1A–H, 2A–D, 3A–D, 12A–B (misidentification).

Type material. Female lectotype (here designated) and male and female paralectotypes from INDIA: Tamil Nadu: Nilgiris: Masinagudi (=Masnigudi) (11°34’19.84’’N, 76°38’33.77’’E), 942 m alt.; Reimoser leg.; 15 October 1934; repository NHM (no register number specified), examined (only females) from photographs GoogleMaps .

Diagnosis. Males of A. lesserti seem closely related to the males of Arctosa zhaojingzhaoi Li, 2016 as both share a downwardly directed median apophysis, but can be distinguished from the latter by uniformly thick median apophysis, which is narrow distally in A. zhaojingzhaoi (compare Pan et al. 2016: fig. 2A–B to Lu et al. 2016: fig. 1C–F). Females of A. lesserti closely resemble the females of A. indica as both share oval spermathecae with slender stalks, but can be distinguished from the latter by distally narrowing anterior part of median septum, which is uniform in thickness in A. indica , and pear-shaped epigynal atria, which are circular in A. indica (compare Fig. 10 View FIGURE 10 A–B to Fig. 6 View FIGURE 6 D–E and Lu et al. 2016: fig. 1G).

Description. See Reimoser (1934).

Remarks. The NHM collection has three female specimens in good condition under the name A. lesserti , without any male specimen (Hörweg, pers. comm.). Of the three female specimens, two belong to A. lesserti ( Figs 9 View FIGURE 9 A–B, 10A–B) while the third is of Wadicosa ghatica Kronestedt, 2017 ( Figs 9C View FIGURE 9 , 10C View FIGURE 10 ) (compare Fig. 10C View FIGURE 10 with Kronestedt 2017: fig. 15). The male specimen might be lost, so we could not redescribe it here.

The illustrations and colour images of the epigynum of A. mulani presented in Tikader & Malhotra (1980: fig. 248) and Lu et al. (2016: fig. 1G) respectively do not match the original illustrations of Dyal (1935: fig. 46), but clearly indicate that these authors misidentified specimens that actually belong to A. lesserti (compare Fig. 10 View FIGURE 10 A–B to Tikader & Malhotra 1980: fig. 248; Lu et al. 2016: fig. 1G).
