Piranthus mandai Maddison, sp. nov. Figs 270-274 View Figures 270–274
Type material.
Holotype male (specimen JK.91.05.31.0001), in LKCNHM, from Singapore: Mandai Track 15 Trail, 1.4106°N, 103.7783°E, J K H Koh 31 May 1991.
Etymology.
Named for the type locality. Other names: In lab notebooks the informal code for this species was “SGOMG”.
Diagnosis.
In colouration similar to P. planolancis , browns and blacks, but with body more compact and robust, as in P. bakau and P. kohi . Embolus with only a small loop before proceeding distally, and thus P. mandai is second in sequence from least to most rotated embolic bases: P. kohi (Fig. 255 View Figures 255–269 ), P. mandai (Fig. 270 View Figures 270–274 ), P. planolancis (Nafin et al. 2020), P. bakau (Fig. 237 View Figures 237–254 ).
Description.
Male (holotype, specimen JK.91.05.31.0001). Carapace length 2.7; abdomen length 2.5. Carapace with rugose surface, black and dark brown, with a sparse covering of narrow scales that is more or less uniform: there is no bare patch beside the PLE, and no distinct three vertical thoracic lines, but there is a slight condensation of scales into a single vertical thoracic line, similar to that in P. bakau . Clypeus narrow and dark. Chelicerae vertical, dark, with a few pale scales basally. Palp brown. Palp similar to that of P. planolancis , but RTA much shorter (Figs 270-272 View Figures 270–274 ), the shortest known among Piranthus . Legs light to dark brown, with indistinct markings (Figs 273 View Figures 270–274 , 274 View Figures 270–274 ) similar to those of P. planolancis ; darkest in the femur, patella, and tibia of the first leg, and the femora of the other legs. Abdomen brown above, lacking the transverse bands of P. bakau and P. kohi , but with the dark end of the abdomen (Fig. 274 View Figures 270–274 ).
