Diagnosis: Hylopanchax thysi is distinguished from all other Hylopanchax species, except H. paucisquamatus, by the presence of 30 vertebrae vs. 31-33 (Ref. 123864). It is further distinguished from H. paucisquamatus and all congeners except H. multisquamatus by the presence of a hyaline urogenital male papilla with small black spots vs. black, and the presence of a conspicuous reticulate pattern in the flank of both males and females vs. absence or less conspicuous; finally, H. thysi is distinguished from H. multisquamatus by a male caudal peduncle depth-length ratio between 53-59% vs. 40-45%, 24-26 scales in the midlongitudinal series vs. 27-30, 13-14 pectoral-fin rays vs. 11-12, body depth 25.2-27.8% of standard length vs. 20.0-23.7%, female predorsal length between 62.0-64.0% of standard length vs. 66.0-74.8%, and female prepelvic length of 33.7-38.0% of standard length vs. 42.1-45.1% (Ref. 123864).
