Richards, William J., Takuji Yato, & Peter R. Last (2003). Revision of the gurnard fish subgenus
Otohime
(Triglidae:
Pterygotrigla
). Smithiana, Bulletin 2.
The subgenus
Otohime
of the triglid genus
Pterygotrigla
is revised and includes descriptions of six new species (
P. amaokai, P. draiggoch, P. elicryste, P. hafizi, P. soela, and
P. urashimai) and diagnoses of five previously described species (
P. arabica, P. hemisticta, P. multipunctata, P. spirai, and
P.tagala). All are poorly represented in museum collections and are distributed in tropical waters of the Indian and western Pacific oceans. A brief discussion of the genus
Pterygotrigla is provided together with its current species composition. The subgenus
Otohime is unique within
Pterygotrigla in having a very long opercular spine and cleithral spines reduced or absent . The species characters used for identification are the number of joined pectoral-fin rays and second dorsal-rays, colouration of the pectoral fin and first dorsal fin, breast squamation, and number of gill rakers and a few other meristic and morphometric features.
Otohime species are very similar in morphometry and meristics and the extent of intraspecific variation is indeterminable from the small collections available. A brief discussion of the genus Pterygotrigla is provided together with its current species composition that is thought to include the unresolved triglid Prionotus alepis. A range extension is given for
Pterygotrigla macrorhynchus
.
