Etymology: Meiacanthus: Greek, meion = less = lessen + Greek, akantha = thorn (Ref. 45335).
Eponymy: Not a true eponym as this is after a character in Greek mythology; Procne (sometimes Progne – see below), a daughter of King Pandion of Athens. She was metamorphosed into a swallow. The name is used for species which have some ‘swallow-like’ attribute. (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 4 - 5; Raggi dorsali molli (totale) : 25 - 26; Spine anali: 2; Raggi anali molli: 15 - 16. Lunate caudal fin with elongated lobes in both sexes; upper half of body bluish black and lower half abruptly bluish white, posteriorly with few small black spots; dorsal fin basal half black with pale blue stripe composed of 1 spot per membrane broadly joined to the next ; outer half of fin bluish gray with pale thin blue margin and black submarginal line; caudal fin base and lobes black with pale blue upper and lower margins, centroposterior part of fin transparent with dusky rays; pectoral-fin axil without dark spot. Dorsal rays IV-V (rarely IV), 25-26; pectoral soft rays rarely 13; segmented caudal rays 11-12 (typically 11); lateral line present (Ref. 54980).
Body shape (shape guide): elongated.
Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
