Diagnosis: Integument fine, irregularly striated, dorsal and postero-ventral muscle attachment sites not sclerotized; lateral eyes not in capsules; glandularia weakly sclerotized, gland pores and their accompanying setae closely associated, but not on a common platelet; genital field with three pairs of acetabula on more or less triangular plates, males with a single genital plate formed by the fusion of both acetabular plates with the strongly sclerotized pre- and postgenitale; excretory pore with very weak sclerotization; legs without swimming hairs, their claws with ventral claw blade, I-leg-5 ventro-distally with a pair of strong, short, blunt setae, distal leg segments straight; gnathosoma large, posteriorly broadly fused to the little extended antero-coxal plate, rostrum moderately projecting; cheliceral claws extremely large, with dorsal margin distally curved and serrated, proximally concave; palp robust, P-2 with- out projection, P-2 and 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 a pair of large, strong, curved distal claws; a fine distally ramified seta inserted ventro-laterally between the proximal projection and the strong palp claws; clear sexual dimorphism in the shape of the genital field, in general slight sexual dimorphism in the shape of the coxal field; no sexual dimorphism in the morphology of legs, palps and chelicerae.
