Info
Plectranthias hinano is a newly described flag perch, it has been observed in deeper, highly complex habitats on walls and ledges in mesophotic ecosystems, suggesting that the species does not live in shallow coral reefs.
Plectranthias hinano has been collected around Tahiti and observed around Moorea, no other radio reports are known to date.
Similar species: Plectranthias bennetti Allen & Walsh, 2015.
Plectranthias hinano also differs from all of its relatives in morphology and a coloration that includes two indistinct black spots along the base of the dorsal fin and translucent yellow dorsal and anal fin membranes.
The body of the perch is overall bright red in coloration, with the breast and belly mostly bright red to pink.
The dorsal portion of the body is darker red with yellow scale margins and lateral line, on the body is a series of 8-12 pink to white incomplete bars , beginning just behind the orbit and continuing to the base of the caudal fin.
The bars are about 20 degrees off vertical in front and become nearly vertical as they approach the base of the caudal fin.
A black spot, nearly twice the size of the orbit, is located at the base of the dorsal fin spines.
The black spot is interrupted by the nearly vertical white bar that begins below soft rays 1 or 2; a smaller second black spot, slightly smaller than the orbit, is located at the base of the soft rays of the dorsal fin.
The snout, throat, anterior part of the lower lip, upper jaw, and opercula are mostly light pink.
At the on the snout begins a yellow stripe that extends across the upper jaw, under the orbit to the preoperculum.
From the pupil, a lattice-like network of indistinct yellow stripes runs radiating across the iris, between the eyes, across the top of the head, from the ventral edge of the orbit to the origin of the lateral line and the lower edge of the opercula.
The iris is mostly pink with yellow spots radiating outward from the pupil, the pupil is black and tear-shaped, tapering anteriorly.
Spiny part of dorsal fin is predominantly translucent yellow, with upper half of black spot on membrane between spines 7 - 10, lower third of soft dorsal fin is predominantly translucent yellow, upper two-thirds hyaline.
Caudal fin membranes are mostly hyaline with some regions of faint translucent yellow, fin rays white with red margins.
Pelvic fins are also hyaline with faint yellow on rays, anal fin mostly translucent yellow with hyaline margins
Pectoral fins are hyaline with pink edged rays, but the base of the pectoral fins are yellow.
Etymology:
Plectranthias hinano was named for Teurumereariki Hinano Teavai Murphy, former deputy director of the University of California Berkeley Gump Research Station and president of the Te Pu Atitia Cultural Association, in honor of the significant contributions she made to the promotion of Polynesian biocultural heritage and field research in Moorea, French Polynesia.
