Lutjanus adetii
A southwestern Pacific snapper valued as a game fish.
The yellow-banded snapper, also called the hussar, is a marine fish in the snapper family Lutjanidae. It lives in the southwestern Pacific Ocean. While not a major commercial species, it is caught by local fisheries and is popular with recreational anglers.
French naturalist François-Louis Laporte, comte de Castelnau, first described this species in 1873, naming it *Diacope adetii*. He based the description on specimens collected in Nouméa, New Caledonia, by a man identified only as "Mr. Adet," whose full name was not recorded.
This snapper has a fairly deep body, with a standard length about 2.5 to 2.7 times its depth. Its snout is somewhat pointed, the preorbital bone is wider than the eye’s diameter, and it has a well-developed preopercular protuberance and notch. The tongue has a patch of granular teeth, and the vomerine teeth form a triangular patch. The dorsal fin has 10 spines and 14 soft rays; the anal fin has 3 spines and 8 soft rays; both fins have rounded rear edges. The pectoral fins have 17 rays, and the tail fin may be slightly notched or forked. The body is rosy-pink, fading to silvery on the belly, with a dusky to golden stripe running from the middle of the gill cover to the base of the tail fin. A golden patch surrounds the eye and extends onto the snout, and there is a yellow blotch at the base of the pectoral fin. The dorsal and anal fins have white margins. Juveniles have a large red spot on the tail stalk, which some keep as the mid-lateral stripe appears. The fish can reach a total length of 50 cm (20 in), though 30 cm (12 in) is more typical.
Its range is limited to the southwestern Pacific, including eastern Australia, eastern Papua New Guinea, and New Caledonia. In Australia, it occurs from the northern Great Barrier Reef in Queensland south to Sydney, New South Wales, with small juveniles recorded even farther south, and also around Lord Howe Island in the Tasman Sea. It lives from the surface down to 40 m (130 ft) among rocky and coral reefs.
The hussar is a nocturnal hunter. Adults gather in large groups during the day and scatter at night to feed. Off New Caledonia, spawning occurs from August to February, peaking between November and January.
The species is mainly caught by recreational fishers. Its flesh is considered good quality, and it is sold fresh in some local markets, especially in New Caledonia.

Lore & Background
Lutjanus adetii was first formally described in 1873 as Diacope adetii by the French naturalist François-Louis Laporte, comte de Castelnau, with the type locality given as Nouméa on New Caledonia. Its specific name honours 'Mr Adet', who collected the specimens that Castelnau described, though Castelnau did not give Adet's given names.
The species has a relatively deep body, with a standard length of 2.5 to 2.7 times its depth. The snout is rather pointed, and the preorbital bone is wider than the diameter of the eye. It has a well-developed preopercular protuberance and incision. The tongue has a patch of granular teeth, and the vomerine teeth are arranged in a triangular patch. The dorsal fin has 10 spines and 14 soft rays, while the anal fin contains 3 spines and 8 soft rays; both fins have a rounded posterior profile. The pectoral fins contain 17 rays, and the caudal fin may be emarginate or slightly forked. The background colour is rosy-pink shading to silvery below, with a dusky to golden stripe running from the middle of the operculum to the base of the caudal fin. A golden patch surrounds the eye and runs onto the snout, and the pectoral fin base has a yellow blotch. The dorsal and anal fins have white margins. Juveniles have a sizeable red spot on the caudal peduncle, which some retain while the mid-lateral stripe appears.
Lutjanus adetii has a restricted distribution in the southwest Pacific Ocean, occurring in eastern Australia, eastern Papua New Guinea, and New Caledonia. In Australia, it ranges from the northern Great Barrier Reef in Queensland south to Sydney in New South Wales, with small juveniles recorded further south, and also at Lord Howe Island in the Tasman Sea. It occurs from the surface down to 40 m, living among rocky and coral reefs. It is a nocturnal hunter; adults spend the day in large aggregations that disperse at night to forage. Off New Caledonia, the spawning season is from August to February, peaking in November to January.
Reader's Guide
Lutjanus adetii is mainly of interest to recreational fisheries, though its flesh is considered of good quality and it is caught for markets in some localities, especially in New Caledonia. It is caught using hook and line and gill nets, and the catch is normally sold fresh. The hussar is one of the species taken in the coral reef finfish fishery of Australia. While not a major commercial species, its role as a game fish and its presence in local markets, particularly in New Caledonia, give it a modest significance within the southwestern Pacific region. The species' nocturnal foraging behavior and daytime aggregations are notable aspects of its biology, and its restricted distribution makes it a characteristic inhabitant of rocky and coral reefs in the area. The description by Castelnau in 1873, based on specimens collected by Mr Adet, provides the taxonomic foundation for this snapper, which remains of minor but consistent interest to both recreational anglers and local fisheries.

Frequently Asked Questions
Who is Lutjanus adetii?
Lutjanus adetii, widely known as the yellow-banded snapper or hussar, is a deep-bodied marine fish in the snapper family Lutjanidae. The species was formally described in 1873 by French naturalist François-Louis Laporte, comte de Castelnau, who gave it the original name Diacope adetii based on specimens from Nouméa, New Caledonia.
What are Lutjanus adetii's powers/role?
As a mid-water predator in the southwestern Pacific, this snapper preys on smaller fish and invertebrates around coastal and reef habitats. Most adults hover near 30 cm in total length, though the species can reach up to about 50 cm.
Why is Lutjanus adetii important?
The hussar is a popular target for recreational fishing and a modest catch for local fisheries, making it economically meaningful to coastal communities in its range. Ecologically, it helps control populations of smaller reef-associated fish and invertebrates.
Where does Lutjanus adetii live?
This snapper is native to the southwestern Pacific Ocean, with its original type specimens collected in Nouméa, New Caledonia. It occupies coastal and reef-adjacent waters throughout that region.
