-----------------------
Description
Dorsal spines (total): 12 - 13 (usually: 13); Dorsal soft rays (total): 11-12; Anal spines: 2; Anal soft rays: 11-12; Pectoral fin rays: 18-20; Lateral line scales: 17-19; Gill rakers (total): 27-32. Body moderately elongate, the depth: 2.1-2.3 in SL. Max. length: 13.5 cm TL. Depth range: 3 - 40 m.
Color
Pale brown to greyish-brown body sometimes with a bronze tinge, darker scale margins, a broad dark bar behind the eye, a narrower dark bar behind the head, and dark caudal-fin tips. The soft dorsal, anal and pectoral fins may have a yellowish tinge.
Etymology
Chromis: from Greek, chroemo = to neigh. A name dating to Aristotle, referring to a drum (Sciaenidae) and its ability to make noise; Later applied to this damselfish and subsequently expanded to embrace dottybacks, cichlids and wrasses (all perch-like fishes once thought to be related).
weberi: in honor of Max Weber (1852-1937), the “distinguished zoologist of Amsterdam and author of extensive works on East Indian ichthyology”.

Distribution
Red Sea; Indo-West Pacific: East Africa, Persian Gulf, Socotra, Madagascar and Réunion (western Mascarenes) east to Line Islands, north to southern Japan, south to Jervis Bay (A.C.T., Australia) and New Caledonia.
Biology
Inhabits coral and rocky reefs, in channels and on steep outer reef slopes, singly or in small to large schools. Diurnal species. Males and females form breeding pairs, and females lay demersal eggs that adhere to the substrate. The male parent guards and aerates the eggs until the larvae hatch.
Similar species
Chromis lepidolepis looks similar in appearance to several other species. A good system to distinguish between these species is to look carefully at the spots on the fins and at the color of the eye.
Acanthochromis polyacanthus (Bleeker, 1855) - Reported from New Caledonia - Link to the species (here). Best distinguished by 17 dorsal spines, highest number in the family. This fish has a number of color variants, and ranges from whitish to all brown or dark grey, sometimes with a white tail.
Azurina elerae (Fowler & Bean, 1928) - Reported from New Caledonia - Link to the species (here).
Azurina lepidolepis (Bleeker, 1876) - Reported from New Caledonia - Link to the species (here).
Chromis ternatensis (Bleeker, 1856) - Reported from New Caledonia - Link to the species (here).
Pycnochromis amboinensis (Bleeker, 1871) - Reported from New Caledonia - Link to the species (here).
Pycnochromis atripes (Fowler & Bean, 1928) - Reported from New Caledonia - Link to the species (here).
