Diagnosis

Erethistoides sicula differs from both E. montana and E. pipri in having a

longer caudal peduncle (19.6–22.3% SL vs. 14.4–18.4) and shorter pectoral spine (14.6–28.0% SL vs. 30.7–32.1). It further differs from E. montana in having a dorsally projecting bony splint on the opercle immediately posterior to its articular facet with the hyomandibula (vs. splint absent; Fig. 2) and from E. pipri in having a more slender head (13.4–15.1% SL vs. 16.4).
