Anthiadidae (Fairy basslets or Streamer basses)
Etymology: Plectranthias: Greek, plektron = anyhting to strike with, spur + Greek, anthias = a fish, Sparus aurata (Ref. 45335); polygonius: Named for the orange rhomboid-shaped polygons in parallel rows along the lateral midline that distinguish it from all its congeners; Noun in apposition.

背面の脊椎 (合計) : 10; 背鰭 (合計) : 16; 肛門の骨: 3; 臀鰭: 7; 脊つい: 26. This species is distinguished from its congeners by the following set of characters: : colouration when alive, in particular the two rows of orange rhomboid-shaped polygons on the lateral part of the body and an elongated yellow and white third dorsal spine; D X,16; pectoral-fin rays 14, all unbranched; vertebrae 10 + 16; continuous lateral line with 27-30 tubed scales; circumpeduncular scales 10-11; preopercle without antrorse spines (Ref. 122130).
Collected (with hand nets) in highly complex reefs predominantly covered by coralline algae and sponges and crevices of steep reef walls, indicating that this species probably has a wider Pacific distribution and all known individuals have been observed or collected at mesophotic depths, suggesting as with most of its congeners, this species does not inhabit shallow coral reef habitats (Ref. 122130).
