| Remarks | Urogenital papilla: in male, tip blunt within a deep groove posterior to the anus and flanked anterolaterally by a pair of swollen skin folds (accessory folds); each accessory fold roughly triangular in shape, appears to be confluent anteromedially with the heavily plicate skin surrounding the anus; in female, tip needle-like, along the dorsal surface of a robust tube-like structure which also bears the anus, the entire structure is accommodated within a deep pocket anterior to the anal-fin origin. In some specimens, the posteriormost tip of this structure is located within the pocket, suggesting some degree of mobility (Ref. 120657). |

| Diagnosis |
This species is distinguished from Barryichthys algicolaby having a shorter, deeper body (body depth at dorsal-fin origin 10-11% SL vs. 7-8% SL); wider, deeper head (head width at widest point 66-75% HL vs. 55-61%; depth at orbit 30-32% HL vs. 27-29%; interorbital width 27-33% HL vs. 20-24%); the ventral margin of orbit obscured by cheek in ventral view (vs. entire ventral margin of orbit visible in ventral view); shorter abdominal region with fewer vertebrae (17 vs. 21); with fewer ribs (11-12 vs. 15), epicentrals (14-15 vs. 18-19) and total vertebrae ( 38-39 vs. 42-44). Live colour pattern, including body background golden-yellow to olive-brown, a variable number of irregularly shaped light to dark brown markings along dorsal midline, presence of a series of light to dark brown elongate lateral markings forming an incomplete or complete horizontal stripe (Ref. 120657). |
