| Diagnosis | Diagnosis. Assigned to Ichnotropis due to the absence of a well-defined collar, digits not serrated or fringed, subdigital lamellae keeled, and subocular bordering the lip. A slender Ichnotropis with a single frontonasal; subocular bordering the lip; a single anterior loreal; feebly developed head shield striations, prefrontals well separated from the anterior supraocular; and supraciliaries separated from the supraoculars by a series of smaller scales. The new species can be distinguished from other Ichnotropis species based on a combination of the following characteristics: Prefrontals well separated from the anterior supraocular (versus mostly in contact in I. bivittata, I. microlepidota and I. tanganicana); lower number (34–41) of midbody scales rows (44–47 in I. grandiceps and 43–48 in I. robusta sp. nov.); small, depressed head and pointed snout (versus large robust head and rounded snout in I. grandiceps and I. robusta sp. nov.); four supralabials anterior to the subocular (versus mostly five in I. grandiceps and I. robusta sp. nov.); distinctive occipital scale usually extending posteriorly well beyond the level of the parietals (versus large trapeziform occipital wedged between the parietals, not protruding past parietals in I. grandiceps and I. robusta sp. nov.). The new species resembles I. capensis sensu lato in its narrow, pointed snout, with the prefrontals well separated from the anterior subocular. It differs in that the new species exhibits black spots on the chin shields and gular scales (versus immaculate in I. capensis sensu lato) and the absence of a clear upper white dorsolateral stripe that separates the dark black lateral band from the dorsal brown vertebral band (versus present in most I. capensis sensu lato). In the phylogenetic analysis, the uncorrected p distances show that the new species differs by >5.9% for 16S and >12.3% for ND4 sequence divergence from other Ichnotropis species (Table 2).
