Diagnosis (adult female and male). Species of this genus are characterised by having the anterior margin of the epistome with at least one projection; the idiosoma dorsally convex and extensively covered by sclerotised shields; podonotal and opisthonotal shields fused to form a holonotal shield without a distinct line of fusion; setae j 3 and r 3 not inserted on tubercles; the holonotal shield fused with the ventri-anal shield; the exopodal shield undivided adjacent to coxa III; the peritrematal shield and part of the exopodal shield adjacent to coxa IV fused into a single unit, which is either fused to the ventri-anal shield or separated from it by a narrow line of unsclerotised cuticle; metapodal shield typically indistinct, either fused to neighbouring shields or, often, apparently longitudinally elongate and located externally to and along the posterior end of the fused peritrematal and exopodal shields.
