Gnathosoma. Pedipalps 3-segmented: a trochanter which lacks setae, fused femurogenu (femur + genu) which is complemented with 5 or 6 setae, and tibiotarsus (tibia + tarsus) which is complemented with 5 or 6 setae. Tibiotarsi may be complemented with a bladder- or bulb-like apophysis. Pedipalps do not reach beyond the subcapitulum by more than the distal half of the tibiotarsi. Chelicera with or without seta near the cheliceral digit. Subcapitulum with 4 pairs of setae (hg1–4) are present; setae hg4 is often the longest. 2 pairs of adoral setae are present or absent.
Idiosoma, dorsal. Female with proterosomal shield (absent in Cunaxoides ulcerosus) which is complemented with two pairs of setae (lps and mps) and two pairs of setose sensillae (at and pt) and may bear a hysterosomal plate complemented with a varying number of setae; when present the dorsal hysterosomal plate may be fused with the proterosomal shield. Dorsal plates well demarcated or not. Dorsal setae c1–h1 are present; c2, f2 and h2 may also be present. If f2 is present, f1 and f2 may be located together on a small platelet. Setae not on larger plates may be born on small platelets barely larger than the setal socket. Cupule im present laterad and posterior of e1. Integument that is not covered in shields or plates is striated
Idiosoma, ventral. Coxae of female vary in size, from being restricted to the trochantral bases to being extensive and nearly forming a holoventral shield. Coxae may or may not be well demarcated. Coxae I–II fused (usually) or not, coxae III–IV fused (usually) or not. Coxae I–II may coalesce medially to form a sternal shield. The genital plates each bear 4 setae (g1–4); 2 pairs of genital papillae visible underneath the plates. The anal plates bear one pair of setae (ps1); one pair of setae is present ventrally on the integument near the anal plates (either ps2 or pa). Cupule ih is present ventrally laterad the integumental setae associated with the anal plates. The integument that is not covered in shields or plates is striated. Legs. Tarsi never constricted apically so as to end in lobes. Trichobothrium on leg tibia IV present. Ambulacral claws are rippled and occur on either side of a 4-rayed empodium.
