Stenorhynchosaurus superficially shares affinities with the Brachaucheninae Benson and Druckenmiller, 2014, preserving a long, relatively straight-sided snout with homodont dentition (Hampe, 2005; this work).
Two characters of the mandible, the mandibular glenoid fossa lying just posterior to the occipital condyle [10.1] as in Megacephalosaurus eulerti and Brachauchenius lucasi (although not shared with Kronosaurus queenslandicus MCZ 1284); and a retroarticular process inflected slightly posteromedially [123.1] as in Kronosaurus queenslandicus (MCZ 1284), Megacephalosaurus eulerti and Brachauchenius lucasi (Benson & Druckenmiller, 2014, and references therein), are shared, together with homodont and dentition [133.0], as in Megacephalosaurus eulerti (Schumacher, et al., 2013) and Brachauchenius lucasi (Williston, 1907).
The genus is diagnosed in having an interrupted post-labial fold, broad isthmus, gill openings not extending ventrally onto undersurface of head, 14-16 branched pectoral-fin rays, lower lip not connected to the base of the maxillary barbel by a skin flap, sulcus between the lip and the barbel, homodont dentition, teeth pointed, coni-form in both jaws, premaxillary tooth patches contacting each other but not confluent, not extended posterolaterally, laterally blunt; dilator operculi muscle and levator opercula muscle contacting each other, broad anterior end of sternohyoideus muscle, its width almost equal to the width in the axilla of the pectoral fin, adductor pelvicalis superficialis muscle not contacting its antimere at the midline (Zhou et al.
