背的軟條 (總數) : 75 - 87; 臀鰭軟條: 59 - 68; 脊椎骨: 40 - 43. This species is distinguished by the following characters: anterior nostril placed low on snout; tip of opercular spine free; 2 pairs of psedoclaspers, inner one positioned in front of outer one; eyes not visible (eyes minute black dots in specimens less than 20 mm SL); head naked; otolith with fused colliculi; 3 lower preopercular pores; maxillary strongly vertically expanded posteriorly, knob at rear corner; 5-7 prolonged rakers on anterior gill arch; anterior anal fin pterygiophore elongated; pseudobranchial filaments absent (Ref. 55786).
這種被藉著下列的特徵區別: 前鼻孔放置了在吻上的低處; 鰓蓋棘的頂端分離; 2 對 psedoclaspers, 內部的在外部的之前放置; 眼看不見的;(眼在標本的細小的黑色點少於 20 mm SL) 頭部裸露的; 用融合的 colliculi 的耳石; 3個低的前鰓蓋骨孔; 上頜骨強烈地垂直地在後部地擴大, 在後面的角落癤瘤; 延長耙的 5-7 在前面鰓弓; 前面的臀鰭支鰭骨延長; 偽鰓絲狀突起不存在。 (參考文獻 55786)
Uncommon species found in caves and sinkholes (Ref. 34024). Associated with the blind synbranchid fish Ophisternon infernale (Hubbs, 1938) and several blind crustacean species. In only one cave, it was found with the catfish Rhamdia guatemalensis (Günther, 1864). This species does not react to flashlights, but darted away at the slightest vibration; it seems to feed on troglobitic shrimps and mysids. Newly-born juveniles are light yellow and about 20 mm long (Ref. 55786).
稀有的種發現於洞穴與陰溝的入口處。 (參考文獻 34024) 伴隨著盲眼的 synbranchid 魚 Ophisternon infernale(Hubbs, 1938) 與一些盲眼的甲殼類的種.。 在只有一個洞穴中，它被與鯰魚 Rhamdia guatemalensis 一起發現。 (Gunther, 1864) 這種不會對手電筒產生反應, 但是在最輕微的震動離開衝出.; 它似乎覓食穴居的蝦與糠蝦。 最近-天生的稚魚是淡黃色的大約 20 mm 長.(參考文獻 55786)
