AMS IA. 6690, holotype of Peristedion (Panichthys) picturatum lingi, 249 mm SL, south head of Sydney Harbor (33 ° 51 ’S, 151 ° 21 ’E), Australia, 5 Apr. 1933; HUMZ 58873, 1 specimen, 259 mm SL, Odawara Fish Market, Odawara, Honshu, Japan; HUMZ 87415, 1 specimen, 271 mm SL, South China Sea; HUMZ 207289, 207290, 2 specimens, 186, 131 mm SL, just north of Townsville (18 °00’S, 147 °01’E), Queensland, Australia, 224–228 m, 9 Jan. 1986; NSMT-P 54651, 1 specimen, 165 mm SL, Sanya Fish Harbor, Hainan, China, 4 Mar. 1997.
Diagnosis
Diagnosis. A species of Satyrichthys with four lip and three chin barbels; many dusky spots on spinous dorsal fin; antrose spines on upper lateral bony plates of caudal peduncle; parietal bones of each side equal in size on midline.
Distribution
Distribution.Japan, South China Sea, Philippines and Australia, in depth of 80– 228 m.
Discussion
Remarks. Herre (1925) described Satyrichthys welchi from the Philippines based on one specimen. Unfortunately, the holotype of this species was destroyed during World War II (Yatou & Okamura 1985). Peristedion (Panichthys) picturatum lingi was described by Whitley (1933) on the basis of the holotype and one paratype from Australian waters. Later, many ichthyologists included this species in Satyrichthys as S. lingi (e.g., Paxton et al. 1989, 2006; Kawai 2008). A comparison of the holotype of S. lingi and the original description with other material of S. welchi reveals similar meristics and relative measurements (Table 8). As the original description of S. welchi is also similar to the holotype of S. lingi. I conclude that S. lingi is a junior synonym of S. welchi. Del Cerro and Lloris (1997) synonymized S. welchi with S. moluccensis without evidence. Satyrichthys welchi is easily distinguished from S. moluccensis by its four lip barbels, three chin barbels, and many dusky spots on the spinous dorsal fin [vs. three lip barbels, zero (rarely two) chin barbels and no spots in S. moluccensis). One paratype (AMS IA. 5810: Fig. 13) of Whitley’s species is identified as Peristedion liorhynchus (Günther, 1872) in having a combination of upper jaw teeth absent, lateral margin of head smooth, posterior pairs of bony plates in the lower lateral rows contralaterally sutured along the midline, and the rostral projections broad and spatulate (Yamada 2002; Kawai & Yabe 2006; Kawai 2008).
