簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 8-10; 臀鰭軟條: 14 - 16; 脊椎骨: 28 - 29. Can be distinguished from all its congeners by the following combination of characters: 25-29 scales in longitudinal series; pectoral fin with vertical rows of small dark gray spots or dark gray bars in males; frontal squamation F-patterned, anterior section of supraorbital series of neuromasts continuous; dark marks on flanks mainly longitudinally arranged in females; body depth 21.3-24.6% SL in males and 18.1-23.8% SL in females; caudal peduncle depth 15.5-17.1% SL in males and 14.7-15.7% SL in females; head depth 69.4-75.4% SL in males and 65.2-68.1% SL in females; and 4-5 bars or transverse rows of spots on pectoral fins in males (Ref. 57947).
能在組合特徵之後被與它所有的同類區分藉由: 在縱向的系列中的 25-29個鱗片; 在雄性中胸鰭有呈縱向列的小深灰色斑點或深灰色橫帶; 前的鱗片排列 F-式樣, 眶上成列的神經瘤連續的前面部分; 在側面上的深色印記主要地縱向地排列成雌性了; 在雄性與 18.1-23.8% SL 中在雌性的體高 21.3-24.6% SL; 在雄性與 14.7-15.7% SL 中在雌性的尾柄深度 15.5-17.1% SL; 在雄性與 65.2-68.1% SL 中在雌性的頭部深度 69.4-75.4% SL; 而且在雄性中的在胸鰭上的 4-5 橫帶或橫跨的列斑點.(參考文獻 57947)
