Diagnosis Trunk tubercles: tall slender and similar tubercles on the first coxae and to a lesser extent on the dorsodistal tip of the femora. Lateral processes: without tubercles. Ocular tubercle: short, carried almost horizontally, eyes at tip, prominent. Proboscis: quite short, recurved back ventrally under cephalic segment. Abdomen: very short, not extending to distal rim of second coxae, fourth leg pair. Palps: very short, terminal segment mounted laterally at base of shorter third segment forming subchelate, structure. Oviger: fourth segment longest, with constrictions suggesting additional segments beyond fourth are coalesced, armed with few distal spines. Legs: moderately short, first coxae with tall slender dorsodistal tubercle equal to but more slender than median trunk tubercles. Femora: with slender dorsodistal tubercle shorter than those of sole setae. Propodus: well curved, longer than short second tibiae, with row of short sole spines, claw short, robust, auxiliaries lacking (Ref. 9).
