简单描述 型态特徵 | 形态测量图

Diagnosis: The dorsal finlet is fan-like and 3-spined, its height more than half of predorsal length, 58-84% (vs. 4-spined in P. smithi, low profile in P. rubrocinctus); first 2 spines of finlet more closely spaced than the 2nd and 3rd. Lateral line deflection is usually located below interspace between 14th and 15th dorsal fin elements. Upper lip fimbriae more numerous than those of lower lip. Base of pectoral fin usually naked or rarely with a single scale on its upper portion (Ref. 56973).
鉴别: 背部小鳍是扇状的与 3-有背骨的, 它的高度超过一半的前背长度, 58-84%;(vs.4-有背骨的在 P. smithi 中, 低矮外形在 P. rubrocinctus 中) 小鳍的最初 2根棘更多间隔很密的超过第二与第三个。 侧线歪斜通常是在第 14 与第 15个背鳍要素之间的间隙之下设置。 上嘴唇毛缘众多的超过下唇的。 胸鳍基底通常裸露的或很少有鳞片在它的上面部分.(参考文献 56973)

生物学特性     字汇 (例如 epibenthic)

Known from shallow reefs; inhabits the margins of sand flats in small caves and below reef walls at depths of 1 to 6 meters; these areas are deposits of coarse gravel largely composed of f fragments of mollusc shells, crustaceans, corals, calcareous algae and sea urchin skeletons and spines. Found buried in the gravel, with just the eyes and the dorsal finlet exposed; it appears to 'swim' in the gravel; solitary or in groups. Associates with other sand-dwelling fishes such as Dactyloscopus tridigitatus, D. crossotus, Gillellus greyae, and toadfish Thallasophynne punctata; also an unidentified shrimp and juveniles of crabs (Callinectes sp.).
