Diagnosis Trunk, short, compact, fully segmented, with 3 -4 short dorsomedian setae. Lateral processes short, closely spaced, glabrous. Neck very short, ocular tubercle at narrowest part, dorsal to oviger implants, with large prominent eyes. Proboscis bottle-shaped, broadest at base, tapering to ovoid shape with moderately long distal tubular area. Lips, narrow flat in adults, tripartite and splayed apart in juveniles, without distal setae field. Abdomen short, not as long as tip of first coxae of fourth leg pair. Chelifores massive, scapes, short, with single median and few short distal setae. Chelae with large triangular palm, short fingers. Immovable finger with rounded end tubercle, of immovable finger, with few short ectal setae. Palps lacking. Ovigers with long fifth segment bearing a laterodistal apophysis with several short spines. Strigilis segments short, with typical spines, terminal claw shorter than terminal segment, with 3 - 4 short endal teeth. Legs moderately long, with rows of short spines on both tibiae, some associated with low tubercles. Tarsus short, with one stout sole spine. Propodus short, well curved, with 3 larger heel spines and 5 - 6 smaller sole spines. Claw robust, well curved, long in relation to propodal length. Without auxiliaries. Female slightly larger, neck and proboscis longer than those of male. Ovigers without fifth segment apophysis, shorter (Ref. 9).
