Genus Ljania Thor, 1898

Diagnosis: Character states of the family, such that: dorsum nearly completely covered by a sclerotized dorsal plate. Plate bearing 4 or 5 pairs of setae. Venter nearly covered by 3 pairs of plates with surfaces finely punctuate and reticulate in form of a network of honeycomb­shaped areas. Plates of each side variously fused, suture lines between plates II and III or between plates I and II, and II and III, medially incomplete. Plates of two sides completely separated medially by membranous integument. Coxal plates I bearing 2 pairs of setae, plates II bearing 1 pair of setae and plates III bearing 1 pair or 2 pairs of setae. Unpaired excretory pore plate with 2 pairs of setae variously shaped and bearing excretory pore located posteriomedial to coxal plates. Legs each with 5 movable segments, second segments partially divided by incomplete suture lines in some species. Cheliceral bases medially fused.

Characters valid for the genus: Dorsal plate and coxal plates with reticulation. CX­I separate, CX III bearing 1 pair of setae, C4 anteriorly. Expp broadly obcordate and occupying nearly entire region posterior to CX­III, Expp bearing setae E1 and E2 (or, rarely additionally setae V2).
