Description

Body depth contained 2.7 to 3.2 times in standard length (for fish 13 to 42 cm standard length). Head length contained 2.2 to 2.4 times in standard length; interorbital area flat to convex, the dorsal head profile almost straight; preopercle angular, with 2 to 4 distinctly enlarged serrae at angle; upper edge of operculum slightly convex; posterior nostrils not much larger than anterior nostrils; maxilla reaches to below rear half of eye, the ventral edge with a low step at the distal expansion; midlateral part of lower jaw with 2 rows of teeth, the inner teeth larger than outer ones.Gill rakers 8 or 9 on upper limb, 16 or 17 on lower limb. Dorsal fin with XI spines and 14 or 15 rays, the third or fourth spine longest, its depth contained 2.5 to 3.0 times in head length and longer than longest dorsal-fin ray, the interspinous membranes deeply incised; anal fin with III spines and 8 rays; pectoral-fin rays 17 to 19; pectoral-fin length contained 1.7 to 2.0 times in head length; pelvic fins not reaching anus, their length contained 2.1 to 2.3 times in head length. Lateral-body scales distinctly ctenoid and without auxiliary scales; lateral-line scales 55 to 62; lateral-scale series 103 to 122. Pyloric caeca 7.
Colour: Generally pale brown, with small dark brown (or greyish green?) spots unevenly scattered on dorsolateral parts of head (posterior to eyes) and body, dorsal fin and caudal fin; no spots on body below level of pectoral fins or on anal and paired fins. According to Postel et al. (1963), juveniles have 6 or 7 dark lines running horizontally along the body and these disappear with age.

Distribution

Indo-West Pacific from Natal, South Africa, Mozambique, Réunion, Mauritius, New Caledonia, Philippines, New Guinea, New Ireland, and Fiji. Not known from the Red Sea or Persian Gulf.

Ecology

E. magniscuttis is known only from deep water (128 to 300 m) in the vicinity of coral reefs. Biology unknown.

Size

According to Postel et al. (1963), this species attains 150 cm total length and a weight of 50 kg.

Interchangeable taxa

E. magniscuttis is closely related to E. epistictus, which has fewer (and smaller) dark spots on the head and body, and in juveniles the dark spots are arranged in 3 longitudinal rows on the body. E. pseudomorrhua was described by Postel et al. (1963) in the same paper with their description of E. magniscuttis. These two species were separated in their key to species on the basis of scale counts (E. magniscuttis was said to have only about 75 lateral-scale series), but they were not otherwise compared. The colour patterns that they illustrated for these two species are virtually identical, and both species were caught only in deep water. Heemstra and Randall (1993) have not been able to examine the holotype of E. magniscuttis (which was deposited at the oceanographic station in Nossi Bé, Madagascar), but if the lateral-scale count is not erroneous, it probably represents an individual anomaly.
