Holocentridae - Squirrelfishes

Myripristis berndti Jordan and Evermann, 1903
Myripristis berndti Jordan and Evermann, 1903: 170 (Hawaii).
Myripristis murdjan (non Forsskal).- Greenfield, 1965: 240 (Clipperton Island).

Abundant, numerous individuals seen on outer slope in caves and crevices between 15-40 m; small to large adults; nocturnal benthic; solitary or in groups; carnivore: large zooplankton (crustacean larvae, etc.); spawns pelagic eggs; 24 cm SL; Indo-Pacific to the Americas; underwater photographs; resident; specimens at USNM (as M. murdjan), LACM.

Myripristis clarionensis Gilbert, 1897
Myripristis clarionensis Gilbert, 1897: 441 (Clarion Island).
Myripristis clarionensis.- Greenfield, 1965: (Clipperton Island)

Common on outer slope in caves and crevices between 15-40 m; juveniles and adults; nocturnal benthic; solitary or in groups; carnivore: large zooplankton (crustacean larvae, etc.); pelagic eggs; 18 cm SL; TEP, from Revillagigedo Islands and Clipperton only; 5: 70-110 mm SL; underwater photographs; resident population; specimens at USNM, LACM.

Myripristis gildi Greenfield, 1965
Myripristis gildi Greenfield, 1965: 241 (Clipperton Island).

Not seen or collected by us; nocturnal benthic; solitary or in groups; carnivore: large zooplankton (crustacean larvae, etc.); pelagic eggs; 25 cm SL; endemic to Clipperton Island; although we actively searched for this species we may not have recorded it because its close resemblance to M. berntdi (which greatly outnumbered M.gildi in collections made in the 1950s); resident on the basis of its restriction to Clipperton; specimens at UCLA, US NM, LACM.

There are four members of this genus in the TEP (Allen and Robertson 1994, Fischer et at 1995) M. berntdi, M. clarionensis, M. gildi, and M. leiognathus. Greenfield's (1965) non-cladistic analysis indicates that, among those species, M. gildi is most closely related to M. berntdi, and he suggested that M. gildi is derived from an ancestor of M. berntdi that previously invaded the TEP. However, since M. berntdi has a number of relatives in eastern Oceania the issue of the phylogenetic relationships and origins of M. gildi remains to be resolved through cladistic analysis of the Pacific and neotropical members of the genus.

Plectrypops lima (Valenciennes, 1831)
Myripristis lima Valenciennes, in Cuvier and Valenciennes, 1831: 493 (Mauritius).

Rare, a single adult collected with rotenone in 30 m; nocturnal benthic; solitary; carnivore: fishes and crustaceans; pelagic eggs; 15 cm SL; Indo-Pacific to the Americas; 1: 63 mm SL; population status uncertain, as it normally inhabits deep water (see Randall et al 1985); specimen at USNM.

Sargocentron suborbitalis (Gill, 1864)
Holocentrus suborbitalis Gill, 1863a: 86 (Cabo San Lucas, Baja California).
Sargocentron suborbitalis.- Fischer et al 1995: 1185 (Clipperton Island)

Fewer than five adults seen by us at —20m depth, and a dozen or so recently recruited juveniles collected by rotenone on the reef flat; numerous specimens collected with rotenone on the reef flat and offshore at the surface in the 1950s; nocturnal benthic; solitary or in groups; carnivore: crustaceans, worms, small fishes; pelagic eggs; 22 cm SL; TEP from Gulf of California to Ecuador, also Galapagos Islands; underwater photographs; resident; specimens at
