Figs 9–13

Type species

Literna rugosa ( Fallou, 1890) .

Diagnosis

Postclypeus strongly compressed laterally with the presence of a deep and narrow furrow on the median part; medial margin of postclypeus composed of two very thick carinae. Very pronounced tegmina veins forming numerous cavities and bumps on the general surface of the tegmina. Presence of a strongly pronounced lobe on the dorso-posterior margin of the pygofer below the anal tube. This very typical character is only observed in Soulieriana gen. nov. and separates it from all other genera within Cercopidae .

Etymology

This new genus is named after the last name of our hemipterist colleague Adeline Soulier-Perkins with the postfix ‘ana’ in reference to Amberana and Bourgoinrana . The gender is feminine.

Description

HEAD. Head wider than long. Ocelli closer to each other than to compound eyes and separated by strong carina extending over the frons to anterior margin of head. Postclypeus compressed laterally; in frontal view, presence of deep and narrow median furrow bordered by edges and forming two clearly bulges striated laterally. Rostrum reaching mesocoxae.

THORAX. Hindlegs with one spine on metatibiae.

TEGMINA. Tegmina longer than wide with large number of bumps, making them strongly embossed; cells of apical network very concave.

MALE GENITALIA. With sterno-lateral plates. Pygofer not straight in its dorsoposterior part; presence of a lobe clearly identifiable just below anal tube. Anal tube with sparsely sclerified area on anterior part.

Distribution ( Figs 9H , 10H , 11H , 12I , 13I )

Endemic genus of Madagascar.
