Anthiadidae (Fairy basslets or Streamer basses)
Etymology: Plectranthias: Bleeker (1873) disagrees with the generic placement of Plectropoma anthioides by Günther. He, therefore, erected Plectranthias to accommodate Pl. anthioides. The name is presumably the combination of the first part of Plectropoma (plectrum), and anthias. Plectrum = Plektron = πλῆκτρον (Greek, plektron = anyhting to strike with, spur + Greek, anthias = a fish, Ref. 45335); purpuralepis: The specific name purpuralepis is a combination of the Latin purpura and lepis, meaning purple scales, in reference to the distinct purple color only present after preservation. The name is treated as a noun in apposition.

संक्षिप्त वर्णन
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 10; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 16 - 17; गुदा कांटा: 3; ऐनल सौफट रेज़: 7; जानवरों की रीड़ का जोड़: 26. This species is distinguised by the following characters: the pectoral and pelvic fins are mostly covered by small scales and scales on the whitish pink blotches turn purple when preserved; D X,16-17 with the 3rd dorsal-fin spine longest; pectoral-fin rays usually 14, all branched except for uppermost ray simple; principal caudal-fin rays 9 + 8; pored lateral-line scales 32036; cheek with 6 diagonal rows of large scales; circumpeduncular scales 14; ca. 7 rows of large predorsal scales, 2 irregular rows of small scales extending to a line through posterior nostrils; maxilla and chin scaleless; posterior margin of preopercle serrated, the ventral margin with 2 antrorse spines; the greatest body depth 32.6-35.1% SL (Ref. 124021).
Cross section: compressed.
This species apparently occurs on rocky reef bottom or slope in the mesophotic zone. Judging from other specimens (Parapercis spp., Plectranthias kamii, P. sheni, Helicolenus hilgendorfii) collected by anglers together with this species, these were taken at depths of 200 m or below (Ref. 124021).
