简单描述 型态特徵 | 形态测量图

背棘 (总数): 5; 背的软条 (总数): 21; 臀棘 1; 臀鳍软条: 17; 脊椎骨: 30. This species is distinguished by the following characters: body color in life light brown dorsally, center of scales whitish, 6 irregular, semicircular brown blotches along back that link narrowly to large dark brown spots on about lower 2/3 of body, with the spots vertically elongate anteriorly, horizontally elongate and darker posteriorly; head orangish brown with small dark brown spots dorsally on snout and nape, 7 narrow bluish white bars (3 on opercle and preopercle, 4 radiating from ventral and anterior part of eye); dorsal and anal fins are translucent whitish, the spinous dorsal with a large black basal spot mainly between the 3rd and 5th spines; rows or round orange spots on soft dorsal fin; small irregular white spots on anal fin; dark brown about lower third of caudal fin with small whitish spots along rays, the rest of the fin light grey with small white and orange spots along rays; D V,21, all rays branched; A I,17 all rays branched; pectoral rays 16-17, branched except uppermost; 57-58 lateral line scales; gill rakers 4-6 + 8-10; lower jaw projecting, 3 pairs of canine teeth anteriorly in jaws; palatine teeth absent; vomerine teeth in a chevron-shaped patch of 3-4 rows; greatest body depth 5.05-6 in SL; head length (HL) 3.5-3.9 in SL; orbit diameter 3.6-4.4 in HL; preopercle's posterior margin with widely spaced, small, blunt serrae; opercle scales ctenoid, cheek scales weakly ctenoid dorsally, becoming cycloid, progressively smaller, nonimbricate ventrally; fourth dorsal spine is the longest, 3.1-3.8 in HL; caudal fin emarginate on dorsal half, often with protruding upper lobe, becoming rounded on ventral half; pectoral fins 5.1-5.4 in SL; pelvic fins just reaching anus (Ref. 79876).
成鱼的尾鳍略圆的, 第二个对第四个分支条略微延长。 有时互相混淆那与日本 P. pulchella 亲源相近, 但是容易地被区分种用它的白色腹鳍, 在 P. pulchella 中那是褐色到黑色, 以及各种不同的其他不同.(参考文献 48636) 淡的红褐色的到灰褐色背面, 颜色变化成微白色的腹地, 在身体的半边侧面上 6 大的子四边形的红黑色的褐色斑点, 狭窄地连接到比较不明显﹐像鞍状斑一样的﹐和深色的斑点在身体背面。 低的尾鳍中的第三到第四的深褐色的红色。 背鳍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。
