Idiosomal length 190‒790. Dorsal plates are well-developed and sometimes combined. OC typically have 2 setae and 2 corneas. PD with 1 or 2 pairs of setae. Dorsal setae 4 or 5 pairs and adanal setae are located on AP. Ventral plates are often combined into a single plate, and epimeral plates frequently include additional (adjunct) setae. Females with 1‒35 pairs of pgs and 1‒2 pairs of sgs. Majority of males with 9‒17 pairs of pgs and 2 pairs of sgs. Palp consists of 4 segments: P2 has a single dorsal seta, P3 lacks setae, and P4 has three setae. Tarsus I includes a dorsolateral solenidion and a famulus, while Tarsus II also has a dorsolateral solenidion. A carpite is found between the end of the tarsus and the central sclerite. In males, tarsus IV bears plumose parambulacral setae. All tarsi have lateral claws only and lack ventral setae. There are 2 or 3 nymphal stages, and when only 2 stages are present, they are the protonymph and tritonymph (Abé 1998; Bartsch 2003; 2006).</p></div>	https://treatment.plazi.org/id/FF7387ABFF89FFC1BCADF977FB741794	Public Domain	No known copyright restrictions apply.
