Brief report to Larva of Pseudochromis sp. (Perciformes, Pseudochromidae)

Somehow, larva of the Pseudochromidae has been no report so far at Japan. Pseudochromidae has been missing also at *Okiyama, 2014.

This photo was shooting at Iriomote Island of Okinawa to early June 2016.

TL; about 25mm. Depth about 3m.

Meristic Characters - D Ⅲ, 22; A Ⅲ 13; P¹ 17(this photo)

Pigment - This larva has orange pigment, it's dispersed throughout over the head and each scale, base of dorsal and anus fin, caudal fin base.

Study - Maybe, I'm thinking either species of Genus Pseudochromis from the Meristic character. Genus Pseudochromis are known six species of the following in sea of Japan. Above all, it seems to be one of the following two.

Pseudochromis tapeinosoma Bleeker, 1853 - (Japanese name : Katsuiro-nise suzume)
D Ⅲ, 21-23; A Ⅲ 12-14; P¹ 17-19; LLp 20-27+4-11; Pred.S 10-15.

Pseudochromis cyanotaenia Bleeker, 1857 - (Japanese name : Ryukyu-nise suzume)
D Ⅲ, 21-23; A Ⅲ 12-14; P¹ 16-20; LLp 23-31+6-11; Pred.S 11-19.

According to the Jeffrey M. Leis & Brooke M. Carson-Ewart(ed.), 2004. Other, following species has similar Meristic characters in Pseudochromidae. but, both those are not been reported from Japan.

genus Assiculus
Assiculus punctatus Richardson, 1846
