簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 5; 臀鰭軟條: 10 - 11; 脊椎骨: 29 - 31. 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).
Erethistoides sicula 在有一個方面有別於 E. montana 和 E. pipri
較長的尾柄 (19.6-22.3% SL vs.14.4-18.4) 與較短的胸棘.(14.6-28.0% SL vs.30.7-32.1) 它進一步在鰓蓋上在有一個方面有別於 E. montana 背面突出多骨的夾板用上顎緊鄰在它的關節刻面後面 (vs. 夾板不存在; 圖 2) 而且從 E. pipri 在有一個方面更細長的頭部.(13.4-15.1% SL vs.16.4)
