Diagnosis

Male pedipalpal femur with a heart-shaped protuberance medially and a projection on the subterminal prolateral surface ( Figs 14I , 15E ); pedipalpal patella with a small, triangular-shaped projection on the prolateral face ( Figs 14I , 15E ); femur, basitarsus and telotarsus of leg I bent, the dividing line between the basitarsus and telotarsus visible ( Figs 14J , 15F ). Female pedipalpal femur 4.30–4.54 times as long as broad, pedipalpal patella 2.93–3.23 times as long as broad.

Etymology

The specific epithet is derived from the Latin word ‘ cordatus ’ meaning ‘cordiform’ and ‘heart-shaped’, which refers to the shape of the projections on the male pedipalpal femur on the subterminal prolateral surface; adjective.

China: Guangxi Zhuang Autonomous Region.

Remarks

The presence of a projection on the prolateral face of the pedipalpal patella has been previously reported for males of S. gibba , S. papillata and S. spinata Zhan, Feng & Zhang, 2023 . The new species can be distinguished by the basitarsus and telotarsus of leg I in lateral view: in S. cordata Zhao, Guo & Zhang sp. nov., basitarsus and telotarsus are bent (in S. gibba basitarsus and telotarsus each have a large columnar projection on the lateral side, in S. papillata and S. spinata basitarsus and telotarsus are straight) ( Zhan et al. 2023; Zhao et al. 2024). Females of the new species are similar to those of S. tengchongensis Yang & Zhang 2013 , but can be distinguished by the following: pedipalpal femur 4.30–4.54 times as long as broad (4.00– 4.13 in S. tengchongensis ); pedipalpal patella 2.93–3.23 times as long as broad (2.66–2.67 in S. tengchongensis ) ( Yang & Zhang 2013).
