DD125902FF9F183FFF28FBD1FA869110.taxon	diagnosis	Diagnosis. Utiaritichthys esguiceroi differs from its congeners by the higher number of perforated scales on the lateral line (99 - 101, vs. 69 - 72 in U. sennaebragai, and 78 - 82 in U. longidorsalis), the higher number of prepelvic spines (17 - 19, vs. 9 - 10 in U. sennaebragai, and 28 - 31 in U. longidorsalis), the lower number of postpelvic spines (20 - 21, vs. 15 - 17 in U. sennaebragai, and 14 in U. longidorsalis), and also by the number of circumpeduncular scales (23 - 25 vs. 30 - 48 in U. sennaebragai, and 33 - 35 in U. longidorsalis). Furthermore, the new species differs from U. longidorsalis by having larger interdorsal width (11.8 - 15.6 vs. 7.1 - 7.9 % of SL), and larger adipose-fin base length (4.2 - 5.8 vs. 3.7 - 3.8 % of SL).	en	Pereira, Thiago N.
