Pterygotrigla was originally described as the genus Hoplonotus by the French zoologistAlphonse Guichenot but this name was invalid as it was preoccupied by Hoplonotus Schmidt 1846, a coleopteran taxon. In 1899 the Australian ichthyologistEdgar Ravenswood Waite put forward the new name Pterygotrigla to replace Guichenot's name. The type species of the genus is Trigla polyommata[1] which was described in 1839 by John Richardson with its type locality given as Port Arthur, Tasmania.[2] This genus, along with the monotypicBovitrigla, makes up the subfamily Pterygotriglinae within the family Triglidae.[3] The genus name, Pterygotrigla, is a compound of pterygion, a diminutive of pteryx, which means "fin", thought to be a reference to pectoral fins of the type speciesP. polyommata and their resemblance to wings, and Trigla the type genus of the Triglidae which was also the original genus of P. polyommata when it was described by Richardson in 1839.[4] The common name used for most of the species classified within this genus is gurnard which derives from the croaking sound they create when caught.[5]
Subgenera and species
There are currently 31 recognized species in this genus:[2][6] and these are classified into subgenera as follows:[4]
Pterygotrigla gurnards are characterised by having the pterygiophores of the spiny dorsal fin flattened into plate-like structures, there are less than 65 scales along the lateral line and they have 26-28 vertebrae in their spine.[10]
Distribution
Pterygotrigla gurnards are found in the Indo-Pacific from the eastern coast of Africa, including the Red Sea, east into the western central Pacific Ocean. They occur as far north as Japan and south to New Zealand.[6]
