Pseudamia is a genus of small marine fish from the family of cardinalfish (Apogonidae) that occurs in the Red Sea , the Persian Gulf and the tropical Indo-Pacific as far as Japan, Palmyra , Tahiti and Australia. The fish live close to the coast to a depth of 64 meters.
features
The different types of Pseudamia are 5 to 21 cm long and have round scales . For cardinalfish, the body of the Pseudamia species is unusually elongated and not high back. The two dorsal fins are far apart. The first is supported by six spines, the second by a spine and eight to nine soft rays; in the anal fin there are two spines and eight to ten soft rays. The caudal fin is rounded or rhombic. It is supported by 17 main fin rays, 15 of which are branched and the top and bottom are unbranched. Supramaxillary (a jawbone) and base phenoid are absent. The ridge of the preoperculum is smooth, the edge sawn or smooth. The Hypuralia 1 and 2 and 3 and 4 are grown together; No. 5 is free. All Pseudamia species have two scaly lateral lines .
Systematics
Pseudamia was established in 1865 by the Dutch ichthyologist Pieter Bleeker and, together with the genera Gymnapogon , Paxton and Pseudamiops, assigned to the subfamily Pseudamiinae within the cardinalfish in 1954 . In 2014 the new subfamily Paxtoninae was created for Paxton in a revision of the systematics of the cardinalfish and Gymnapogon and Pseudamiops were assigned to the tribe Gymnapogonini within the subfamily Apogoninae , so that today Pseudamia is the only species of the monotypical subfamily Pseudamiinae.
