成魚的尾鰭略圓的,第四個分支條的第二個略微延長了。 有時互相混淆那與日本 P. pulchella 親源相近, 但是容易地被區分種用它的白色腹鰭, 在 P. pulchella 中那是褐色到黑色, 以及各種不同的其他不同.(參考文獻 48636) 淡的紅褐色的到灰褐色背面, 顏色變化成微白色的腹地, 在身體的半邊側面上 6 大的子四邊形的紅黑色的褐色斑點, 狹窄地連接到比較不明顯﹐像鞍狀斑一樣的﹐和深色的斑點在身體背面。 低的尾鰭中的第三到第四的深褐色的紅色。 背鰭的刺狀部分的最後薄膜在它的基底 (參考文獻 42740) 幾乎連接到第一背鰭鰭條了。
Coastal species found in shallow estuaries and protected coastal bays to depths of about 25 m (Ref. 48636). Inhabit sand bottoms solitarily (Ref. 90102). Minimum depth reported from Ref. 48636.
