Centrodorsal plate showing either foveate or reticulate cuticular pattern. In nymphal stages posterior part of this plate showing a median lesser sclerotized and slightly concave conspicuous area without distinct surface pattern resembling an inverted Y. Large folds framing centrodorsal plate completely, showing fine granular surface. Orifice of opisthonotal gland (gla) located in posterior third of lateral folds. Ventral sejugal suture developed as distinct furrow, posterior border medially opened over a short distance. Legs monodactylous with large hook-like claws.
