 Description:   
 General features dorsal integument: finely striated (10/10 Mm), inner layer with a honeycomblike structure consisting of regularly arranged fields of fine porosity; muscle attachments: sclerotized, D-1 fused with postfr, postoc, and Dgl-3, occasionally also prefr; D-2 a separate, roundish platelet, D-3 fused with Dgl-4, D-4 free or fused with Dgl-5; V-1–3 as separate, roundish platelets coxal field: mediocaudal margin of Cx-1+2 extending over the level of the apodemes equally rounded, apodemes Cx-2 short and curved, their tips directed laterally; Cx-3+4 subtriangular, with straight caudal margin slightly irregular due to secondary sclerotization.   
I-L: I-L-5 elongated, ventral margin slightly convex near the base, slightly concave in the centre, and strongly diverging from dorsal margin in the sector between ventral seta and base of seta S-1; S-1/2 homoiomorphic, with rounded tips, narrow setal interspace, S-1 more slender and with a knobshaped tip; I-L-6 equally curved, with dorsal and ventral margins slightly converging from the base to the claw furrow.  
excretory pore: posteriorly embraced by an U-shaped sclerite; Vgl-1: fused to Vgl-2  
palp: little sexual dimorphism, ventral margin P-2 weakly concave, with rugosity in its central part, P-3 straight, slightly convex in the centre, P-4 straight, 1: 1: 1, with a fine denticle near proximoventral hair insertion, sword seta halfway between ventral setae or nearer to the distoventral one.
