A New Genus and Species of Cardinalfish (Apogonidae) from the Indo-West Pacific, with a Key to Apogonine Genera

Lachneratus phasmaticus, a new genus and species of cardinalfish (Family Apogonidae), is described from material collected at the Comoro, Fiji, and Hawaiian islands. The new genus is most similar to Rhabdamia Weber based on skeletal similarities, enlarged teeth, relatively smooth preopercular edges and deciduous cycloid scales. Lachneratus differs externally from Rhabdamia in having one to three strong spines on the preopercular edge (none in Rhabdamia), 12 or more dorsal-fin rays (11 or less in Rhabdamia). A key is provided to identify 19 recognized genera of the subfamily Apogoninae, based on external characteristics.

Family Status of Amioides and the Senior Synonym of Coranthus (Percomorpha: Apogonidae)

Amioides, proposed as a synonym of Synagrops about 72 years ago, was recently recognized as a valid genus and provisionally placed in the Acropomatidae. Amioides is moved from Acropomatidae to Apogonidae based on family synapomorphies of having one supernumerary anal spine and a simple swimbladder. The first two anal spines have non-homologous positions in these two families based on the number of serial and supernumerary anal spines. Amioides is the senior synonym of Coranthus, a widely distributed, rarely collected, deep-dwelling cardinalfish (77–276 meters). A single species is recognized with Amioides grossidens as a junior synonym of Coranthus polyacanthus. Pore and free neuromast patterns for Amioides polyacanthus, new combination, are described.
