DIAGNOSIS.—Trunk ovoid in dorsal view, lateral processes closely crowded, with tiny dorsodistal tubercles. Ocular tubercle conical, pointing anteriorly, eyes small, at base of tubercle. Proboscis massive, greatly swollen distally, less so proximally, lips flat. Abdomen moderately long, carried horizontally, bearing small conical dorsodistal tubercle.
Chelifores moderately short, scape with narrowly conical dorsodistal tubercle, chelae oval, with endal fold denoting atrophied finger. Palps long, slender, heavily setose distally, distal segments 5–7 each with ventral projection. Ovigers large, segments 3–6 with many lateral setae, seventh with lateral bulge having many setae, strigilis segments small. Legs with many short dorsal spines, low dorsolateral tubercles on the first and third coxae, moderately long sex pore spur on posterior 4 second coxae, and modest dorsodistal tubercle on each femur. Propodus with 3 heel spines and many lateral and sole setae. Claw slender, auxiliaries about half main claw length.
