Diagnosis Extremely setose/spinose species. Trunk circular in dorsal view, with 4 to 5 short median spines or sometimes spines lacking. Lateral processes contiguous, with many laterodistal setae continuing laterally on all first coxae, also with slender paired dorsodistal tubercles with spines at their tips. Ocular tubercle moderately long, eyes prominent. Proboscis slightly inflated, ovoid. Abdomen very long, with long paired dorsal spines. Palp segments short, second slightly longer than fourth, all with few dorsal setae and few ventral setae on distal 5 segments. Chelifores with many setae on scapes, most longer than segment diameter, and several short dorsal tubercles each with spine. Chela fingers atrophied, with single spine. Oviger with 3 to 4 rows of short spines on major segments, 4 strigilis segments with paired denticulate spines. Leg tibiae with many long dorsal setae, some originating on low tubercles, femur with few similar lateral and ventral setae. Second coxae of posterior 2 pairs of legs with genital spur slightly longer than segment diameter. Femur with dorsodistal tubercle as long as segment diameter, tubercle bearing tiny cement gland tube laterally near tip. Propodus slender, well curved, with 3 major heel spines, 8 to10 very small sole spines, and several lateral and dorsal setae. Claw long, little curved, auxiliaries slender, about 0.6 the main claw length (Ref. 2153, p. 3).
