Short Description
Diagnose after RUTLEDGE, 2019 [27520]: Pseudobatos buthi is distinguished from P. glaucostigmus in having a nasal tassel, uniform coloration, a slightly narrower maximum disc width and disc width at anterior orbit, longer head, longer snout, shorter anterior nasal flap, smaller nostril length, and a smaller body width at first dorsal-fin origin. Pseudobatos buthi is distinguished from P. leucorhynchus in having a nasal tassel, brown rostrum, shorter distance from snout to first dorsal-fin origin, shorter distance from snout to lower caudal-fin origin, slightly narrower disc width at anterior orbit, a narrower body at first dorsal-fin origin, shorter anterior nasal flap base length, and shorter nostril length. Pseudobatos buthi is most similar to P. productus but differs in having a narrower disc width (30–35% vs. 36–38% TL range), shorter distance from nostril to disc margin (2.8–4.0% vs. 4.2–5.2% TL range), narrower disc width at anterior orbit (12–19% vs. 20–22% TL range), narrower tip of snout width (3% vs. 4–6% TL average), and no prominent thorns as a juvenile.
