Subgenus Rhombotettix Rhombotettix Skejo, Yong, Bogic & Kasalo, subgen. nov.

Type species.

Cicada rhombea Felton, 1765 = Phyllotettix (Rhombotettix) rhombeus .

Etymology.

Rhombotettix is a noun of masculine gender made up of combining Latinised Ancient Greek words for rhombus (ῥόμβος, rhombos) and grasshopper (τέττιξ, tettix). This name was selected because of its prosody in the combination with the specific epitheton of the type species, " Rhombotettix rhombeus ".
