Trunk with dark spots of pigment, mucro and legs less pigmented. Ant. IV with nine subsegments; Ant. III with 14 chaetae other than the sensory clubs; Ant. II with 13 chaetae, three of them clearly longer than the others; Ant. I with seven chaetae; some chaetae of Ant. II-IV capitate. Eyepatches lacking interocular chaetae. Head vertex with a total of 16 large spines, two of them unpaired; unpaired chaeta A1 absent; secondarily reduced chaetae near the spines present. Clypeal area with 4+4 mac near the antennae. Trochanters I-III with 1,1,1 spines, respectively, trochanter I spine capitate, II knobbed and III blunt; trochanter III with three regular chaetae other than the spine. Ungues with a single inner tooth, with tunica and weak pseudonychia; unguiculus I with the internal tooth; unguiculus III filament thin and reaching the tip of the unguis III. Large abdomen dorsally with several capitate mac. Female with a long subanal appendage (surpassing the ventral anal valves), blunt, apically serrated on its internal face. Dens ventral chaetotaxy formula from the apex to the base as: 4,1 … 1, dorsal chaetotaxy with 15 chaetae; mucronal notch prominent (adapted from Zeppelini et al. 2018).

Szeptyckitheca kac is unique within the genus due the presence of 4+4 modified mac on the upper clypeus (f line) and the dens ventral chaetotaxy formula of 4,1...1 chaetae. Further data on the species are presented in Table I.
