Figs 41-47

Type material. Holotype: Male, INDONESIA: East Nusa Tenggara, Flores, Pulau Babi , 8°27'S, 122°30'E, E. Jacobson leg. IV.1913 ( SMF) .

Etymology. This specific name is derived from the originally Greek words "dikella" and "keros" which means "two-pronged", referring to the needle-like conductor and embolus of the male; adjective.

Diagnosis. This new species is similar to P vallicola Deeleman-Reinhold 1995 in the male bulb provided with a sub-distal conductor (Fig. 41) and a distal embolus (Fig. 41) and the ratio embolus length: conductor length roughly 1:1, but can be distinguished by the promargin of chelicerae with 2 teeth (the promargin of chelicerae teethless in P vallicola ), the spindly embolus, and bulb clearly longer than tarsus (bulb of same length as tarsus in P vallicola ) (Figs 41-42, 44-46) in the male.

Description. Male (holotype). Total length 2.05; prosoma 1.06 long, 0.83 wide; opisthosoma 1.19 long, 0.68 wide (Fig. 43). Prosoma, suborbicular, yellow, decorated with numerous hairs on the middle of clypeus, and the region behind eyes (Fig. 43). Chelicera yellow, promargin with lamina and two small teeth, and retromargin without teeth, posterior surface of fang provided with 13 small denticles. Sternum palp brown. Opisthosoma yellowish, ovoid (Fig. 43). Legs yellow. Leg measurements: I missing, II 12.94 (3.80, 0.35, 3.81, 3.88, 1.10), III 7.78 (2.08, 0.32, 2.52, 2.64, 0.22), IV 12.98 (3.64, 0.30, 4.05, 3.90, 1.09); leg formula: 4 2 3; palp 2.03 (0.66, 0.17, 0.38, 0.23), bulb 0.39 long, 0.13 wide. Male palp (Figs 41-42, 44-46): Male palp: femur, patellar, tibia and tarsus with numerous long, strong spines, bulb pale yellow elongate, conductor (Fig. 41) dark, needle-like, embolus (Fig. 41) slender, embolus and conductor slightly diverging.

Female: Unknown.

Distribution. Known only from the type locality (Fig. 47).
