Signoretia Stål, 1859: 289.

Type-species.

Thamnotettix malaya Stål, 1855.

Diagnosis.

Head ( Figs 10-14 ) weakly to strongly produced. Pronotum ( Figs 10, 11, 13, 14 ) with longitudinal carinae absent or, if present, weakly developed and not extended entire length. Forewings ( Fig. 19 ) with claval veins separate throughout length.

Notes.

Signoretia currently includes 10 Oriental species and 15 Afrotropical species, in addition to the new species described herein. Members of Signoretia can be easily distinguished from Preta by the lack of paired complete longitudinal carinae on pronotum ( Figs 10, 13 ) and separate claval veins on forewings ( Fig. 19 ). Several nominal species do not have the male genitalia described and illustrated, specially the Oriental ones.
