| Diagnosis | Diagnosis: Phymaturus katenke is a member of the patagonicus group, distinguished from the palluma group by having superciliaries that are flat and imbricate rather than rectangular and non-overlapping; slightly spiny and nonrugose caudal scales in verticilles, and two rows of lorilabial scales between the subocular and supralabial scales. Phymaturus katenke is distinguished from P. spurcus, P. patagonicus, P. felixi and P. desuetus by its larger adult body size (Tables 2, 3). Absence of sexual dichromatism differentiated P. katenke from the examined P. camilae, P. spurcus and P. felixi, and from P. ceii Scolaro & Ibargüengoytía 2007, P. videlai Scolaro & Pincheira-Donoso 2010, P. castillensis Scolaro & Pincheira-Donoso 2010 and P. tenebrosus Lobo & Quinteros 2005. Moreover, the color pattern of P. katenke is different from those observed in other monochromatic species such as P. etheridgei Lobo et al. (2010), P. curivilcun, P. patagonicus or P. indistinctus Cei & Castro (1973). Three traits (number of supralabials, scales between rostral and interparietal, and scales around midbody) distinguish P. katenke from all examined species. Supralabial scales and scales between rostral and interparietal were more numerous in P. katenke, while scales around midbody were more numerous in P. spurcus, P. manuelae, P. camilae, P. felixi and P. desuetus (Table 2). Phymaturus katenke differs from P. spurcus. P. patagonicus, P. camilae, P. felixi, P. curivilcun and P. desuetus in its larger axila-groin distance, head width and, with the exception of P. patagonicus, limbs length. A higher number of ventral scales distinguishes P. katenke from P. patagonicus, P. curivilcun and P. camilae. Phymaturus katenke has more infralabial and dorsal scales than P. manuelae and distinguishes it from P. spurcus. P. patagonicus, P. curivilcun and P. felixi (Tables 2, 3). Phymaturus katenke has a fragmented into two subocular scale, a trait normally not present in P. patagonicus, P. felixi or P. camilae (Scolaro et al. 2021). |

| Etymology | The specific epithet “katenke” (which means watercourse, or “corriente de agua ̈ or “mucha agua” in Spanish) comes from the Tehuelche language and refers to the name of the farm where the holotype was found. |
