What is "onomarchus"

Onomarchus ( Greek: Ονόμαρχος) was general of the Phocians in the Third Sacred War, brother of Philomelus and son of Theotimus. After his brother's death he became commander of the Phocians and pursued a warmongering policy until his final defeat.

Onomarchus is a genus of true katydids found mainly distributed in the tropical forests of Asia. Like many other members of the subfamily Pseudophyllinae, their wings appear very leaf-like.

A study of O. uninotatus found it to produce sounds at an unusually low frequency of about 3.5 kHz. The tympanal membrane cuts out high frequencies unlike the sound filters found in other Tettigoniids.

The species in the genus include

• Onomarchus bisulcatus Ingrisch & Shishodia, 1998
• Onomarchus cretaceus (Serville, 1838)
• Onomarchus leuconotus (Serville, 1838)
• Onomarchus philippinensis Weidner, 1965
• Onomarchus uninotatus (Serville, 1838)
