Subgenus Hygrobates (Lurchibates) Goldschmidt & Fu, 2011

Diagnosis: Integument fine, irregularly striated, glandularia little sclerotized, lateral eyes not in capsules; genital field with 3 pairs of acetabula; excretory pore with very weak sclerotization; legs without swimming hairs, I-leg-5 ventro-distally with a pair of strong setae, I-leg-6 straight; gnathosoma large, posteriorly broadly fused to the anterocoxal plate; cheliceral claws extremely large, with dorsal margin distally curved and serrated, proximally concave; palpus robust, P-2 without projection, P-3 ventrally smooth or denticulate, P-5 short, compact and formed like a grasping organ due to the presence of a proximo-ventral extension (flat to extended, pointed) and two strong, curved distal claws. There is a clear sexual dimorphism in the shape of the genital field (for details see Goldschmidt & Fu 2011).
