THE CORAL TRIANGLE: HEARST BIODIVERSITY EXPEDITION 
Trachonurus villosus (Gunther, 1878) (Fig. 60) 
Material.— CAS uncat. (1, 58.7 mm HE, 340++mm TL); HEPD-012, beam trawl in 721-761 m. CAS 
235503 (61.6 mm HE, 345 mm TE, DC-1411); HEPD-016, otter trawl in 892-966 m. 
Remarks.— Trachonums has several nominal species; all are closely similar and difficult to distinguish; 
more taxonomic sRidy is necessary. Numerous specimens were collected by the Albatross during its 
1907-1910 expedition to the Philippine and Indonesian ai'chipelagos. Trachonurus villosus is apparently 
widespread in the northwestern Pacific. 
Ventrifossa longibarbata Okamura, 1982 (Fig. 61) 
Material.— CAS 236398 (62.4 mm HE, 310+ mm TE, DC-1555); HEPD-035, beam trawl in 397-439 m. 
Remarks.— Previously known firom southern Japan, Okinawa Trough, and Taiwan in 382-1211 m. The 
HEPD specimens represent the first record of the species fi'om the Philippines. 
Ventrifossa macroptera Okamura, 1982 
Material.— CAS 233997 (5, 31.3^3.5 mm HE, 175-207 mm TE); HEPD-006, otter trawl in 454-457 m. 
Remarks.— These HEPD specimens represent the first record of the species from the Philippines and the far¬ 
thest south. It was previously known from the Kyushu-Palau Ridge and off Taiwan. Ventrifossa sazonovi 
Iwamoto and Williams, 1999 from off Vietnam and Western Australia also has a smooth spinous second 
ID ray, but that species has shorter P (1.5-1.9 time in HE vs. 1.3-1.5) and enlarged spinules on scales along 
the dorsum in adults. 
Ventrifossa saikaiensis Okamura, 1984 (Fig. 62) 
Material.— CAS 235515 (2, 48.4-58.7 mm HE, 240+-287+ mm TE, DC-l 382, -1 390); HEPD-012, beam 
trawl in 721-761 m. CAS 235517 (55.9 mm HE, 295+mm TE, DC-1406); HEPD-015, beam trawl in 
757-836 m. CAS uncat. (61.6 mm HE, 345 mm TE); HEPD-016, otter trawl in 892-966 m. 
Remarks.— Known only from tlie Okinawa Trough, Taiwan, and the South China Sea off Euzon, in 
280-1211 m. 
Ophidiidae (Brotueas and Cusk-Eees) 
Dicrolene tristis Smith and Radcliffe in Radcliffe, 1913 
Material.— CAS 235740 (2, 116-161 mm SE, DC-1309); HEPD-006, otter trawl in 454-457 m. CAS 
235468 (175 mm TE); HEPD-016, otter trawl in 892-966 m. 
Remarks.— Known from southern Japan, Taiwan, and the Philippines in approximately 560-990 m. 
Glyptophidium japonicum Kamohara, 1936 (Fig. 63) 
Material.— CAS 233982 (123 mm SE, DC-1286); HEPD-003, beam trawl in 272-291 m. 
Remarks.— The genus was revised by Nielsen and Machida (1988); five of the seven species are known 
from off the Philippines. 
Glyptophidium lucidum Smith and Radcliffe in Smith, 1913 (Fig. 64) 
Material.— CAS 235750 (5, 130+-175+mm SE); HEPD-006, otter trawl in 454-457 m. CAS 235801 (188 
mm SE, DC-1446); HEPD-019, beam trawl in 541-636 m. 
Remarks.— This is a common species known from the northern Philippines south to NW Australia, in 
395-685 m. 
Hoplobrotula armata (Temminck and Schlegel, 1846) (Fig. 65) 
Material.— CAS 235795 (207 mm SE, DC-1550); HEPD-033, beam trawl in 225-347 m. 
Remarks.— The HEPD specimen probably represents the first record of the species from the Philippines. 
The species is known from southern Japan, Okinawa, and Taiwan in upper-slope depths (in approximate¬ 
ly 200-350 m).
