亞洲: 印度的曼尼普爾州到泰國半島接近馬來邊緣。 採集自雅魯藏布江，親敦江, 西塘江與薩爾溫江流域了，而且較小的溪流沿著泰國半島的西岸，在安達曼海出海的所有河川與在眉隆與塔披河流域，在泰國灣出海的所有河川。 已經不再在依洛瓦底江中收集了, 但是確定地在那裡確實出現。

Paracanthocobitis zonalternans differs from all its congeners by combination of the following characters: lateral line incomplete, ending near insertion of dorsal fin; dorsal fin with 9½-10½ branched rays; presence of axillary pelvic lobe; series of black blotches, usually without black stripe but with faint dusky stripe, along side of body, usually ending near dorsal-fin insertion; circular black spot on upper margin of caudal-fin base; black pigment extending from lateral stripe onto pectoral-fin base; absence of marmorated pattern anterior to origin of dorsal fin; dorsal saddles short, rarely connecting to lateral blotches; and upper caudal fin with 8 (occasionally 7) branched rays (Ref. 117351).
與出現在達到最多高於腹鰭的一條不完全側線的 Indochinese 區域的它的同類區分了; 眶下的鰓蓋出現在雄性。 (參考文獻 39226)
Found in a variety of streams from river mainstreams to small brooks. Apparently avoids mountain streams with steep gradient and prefer shallow riffles over small pebbles above which its marmorated color pattern makes it inconspicuous from the surface. Also collected on a muddy to sandy substrate with a few stones and numerous gastropod shells in depths ranging from 0.05 to 0.5 m.
發現於從河主流到小的小溪多種溪流了。 似乎避開山地溪流具有陡峭的。 似乎偏愛在小的小圓石上的水淺急流在那上面它的大理石彩色斑紋從表面使它不明顯。 也在一個泥濘多沙的底部上收集在深度範圍從 0.05 到 0.5 公尺中具有一些石頭與很多的腹足動物貝殼。
