Diagnosis.

Phrynarachne lancea males can be easily distinguished from other species by the wide, spear-shaped RTA. Females of P. lancea are similar to P. mammillata in having an M-shaped median plate and kidney-shaped spermathecae. However, P. lancea can be distinguished by the length to width ratio of the median plate (7:1 in P. lancea vs 4:1 in P. mammillata ), the straight posterior edge of the median plate (vs procurved in P. mammillata ), the posterior edge of the spermathecae shorter than the anterior edge (vs of equal length in P. mammillata ), and the longitudinal fertilization ducts (vs transverse in P. mammillata ).

Description.

Female (Figs 11 , 19A ): total length 16.49, carapace 6.53 long, 6.82 wide, white, posterior edge black. Eye sizes and interdistances: ALE 0.21, AME 0.20, PLE 0.24, PME 0.21; ALE-AME 0.14, AME-AME 0.25, PLE-PME 0.33, PME-PME 0.28. Chelicerae white, with two promarginal teeth and one retromarginal tooth; gnathocoxae white with black pattern, labium black, 0.88 long, 0.83 wide. Sternum white. Legs white with black markings, femora I and II with dense, varying-sized tubercles; tibiae and metatarsi I, II with dense asymmetrical ventral spines (I, tibia 28, metatarsus 75; II, tibia 26, metatarsus 68). Leg measurements: I 12.45 (4.23, 4.49, 2.41, 1.32), II 12.15 (4.15, 4.41, 2.31, 1.28), III 6.25 (2.12, 2.38, 0.98, 0.87), IV 5.90 (2.18, 2.00, 0.92, 0.80). Leg formula: 1234. Opisthosoma white, posterior grey, with four obvious brown tubercles.

Epigyne (Fig. 11 ) with sclerotized margins inconspicuous, M-shaped; median plate M-shaped, hood absent, anterior and posterior edges recurved, the ratio of length to width is 7:1; copulatory opening inconspicuous; spermathecae kidney-shaped, the ratio of anterior edge to posterior edge length is 3:1. Fertilization duct longitudinal.
