THE CORAL TRIANGLE: HEARST BIODIVERSITY EXPEDITION 
P. macrocephalus based on differences in D and P ray counts, but he did not include P. rhodochrous in his 
discussion. If the three nominal species are determined to be a single species, its distribution would be 
extremely widespread, ranging from the western Indian Ocean to Hawaii and from Japan south to Indone¬ 
sia and through most intervening areas of the western Pacific. 
Pterois antennata (Bloch, 1787) (Fig. 97) 
Material.— CAS 235573 (105.5 mm SL, DC-1503); HEPD-026, beam trawl in 82-86 m. 
Remarks. — A common, widespread species from most of the Indo-West Pacific, found in lagoons to outer 
reefs in depths to about 76 m. 
Pterois lunulata Temminck and Schlegel, 1842 (Fig. 98) 
Material.— CAS 235752 (91 mm SL, DC-1448); HEPD-021, beam trawl in 132-172 m. 
Remarks.— Distributed throughout the western Pacific from northern Japan and Korea to northern Australia 
Setarches longimanus (Alcock, 1894) (Fig. 99) 
Material.— CAS 236699 (43 mm SL); HEPD-006, otter trawl in 454^57m. CAS 236698 (2, 340-358 mm 
SL); HEPD-009, otter trawl in 322-33 m. CAS 236696 (37.2 mm SL); HEPD-010, beam trawl in 318-333 
m. CAS 235642 (121 mm SL); HEPD-036, beam trawl in 216-262 m. 
Remarks.— A wide-ranging species in tropical to subtropical waters if the Indo-West Pacific. 
Triglidae (Searobins) 
Lepidotrigla abyssalis Jordan and Starks, 1904 (Fig. 100) 
Material.— CAS 236411 (125 mm SL, DC-1489); HEPD-022, otter trawl in 115-144 m. 
Remarks. — Masuda et al. (1984: 334) record the distribution of this species as southern Japan and the East 
China Sea. 
Pterygotrigla hemisticta (Temminck and Schlegel, 1843) 
Material.— CAS 235570 (89 mm SL); HEPD-022, otter trawl in 115-144 m. 
Remarks.— A widespread species ranging from Japan south through the Philippines and China coasts to 
Indonesia and northern Austraha, in 10-420 m. 
Pterygotrigla sp. (Fig. 101) 
Material.— CAS 234010 (187 mm SL, DC-1320); HEPD-009, otter trawl in 322-336 m. CAS 236479 (96 
mm SL, DC-1560); HEPD-036, beam trawl in 216-262 m. 
Remarks.— The genus has yet to be revised, and according to Richards (1999 in Carpenter and Niem FAO 
WCP, vol. 4, p. 2360) . . includes many species, several of which are undescribed.” We were unable to 
identify this specimen. 
Peristidiidae (Armored Searobins) 
Peristedion cf. liorhynchus Gunther, 1871 (Fig. 102) 
Material.— CAS 233996 (2, 116-166 mm SL, DC-1296, -1297); HEPD-006, otter trawl in 454^57 m. 
CAS uncat. (154 mm SL); HEPD-009, otter trawl in 322-336 m. 
Remarks.— In the preserved HEPD specimens, the dorsal fins are clear except for the black margins; P pale 
with broad black band near tip and fainter diagonal black band at mid-fin. Scales of dorsum outlined in 
black along posterior edges. The HEPD specimens do not agree with Richards’s (1999:2370) figure of the 
species (adapted from Okamui'a, 1985) in tenns of the barbel, the P pigmentation pattern and lengtli of free 
rays. That figure also shows a large sharp preopercle spine, which is reportedly absent fide Nakabo (2000: 
610) and Okamura andAmaoka (1997: 216).
