簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 7; 臀鰭軟條: 6. Distinguished from other Hemipsilichthys species by the exposed lateral process of cleithrum above pectoral fin insertion very reduced in size, never passing the origin of the pectoral fin spine; and by the arrangement of the hypertrophied odontodes on the lateral margin of head, which are longer posteriorly and slightly turned backwards (Ref. 42856).
與其他的 Hemipsilichthys 種區分了藉由裸露的匙骨側面突起胸鰭上方嵌入非常縮小的, 從不經過胸鰭棘的起源; 而且肥大的齒對頭部的側面邊緣的安排, 那是藉由後面較長而且些微地向後轉.(參考文獻 42856)
Facultative air-breathing in the genus (Ref. 126274); Found in rocky and stony areas. During the day, this fish hides under the stones in the deep and shaded places but is always active.
