Subcapitulum with or without ventral projections. Setae subc. present or absent. Setae elc.p. present or absent, stick-like if present. Idiosoma slightly elongated, 2–2.5 times longer than wide or vermiform. Idiosomal dorsum and opisthosomal venter with or without transverse striations. Anterior apices of apodemes I fused or not with propodonotal shield or gnathosomal branches (in Gastronyssus ). Apodemes II–IV shaped differently. Median part of idiosomal venter with or without sclerotization. Median transverse sclerite present or absent. Coxal fields I with or without membranous posterior projections. Folds posterior to coxal fields II present or absent. Anal opening situated ventrally or terminally. Projections or folds on leg podomeres present or absent. Coxal fields sclerotized or not. Tarsi of legs I–II distinctly shorter than respective tibiae. Pretarsi absent or present but strongly reduced on legs III–IV. Setae cp, ba I–II, and pR I–II absent. Setae e I–II situated dorsally or antiaxially, represented by alveoli, microsetae or spines; e III–IV present or absent, if present displaced dorsally, represented by alveoli.
