Translation:

Light brown or yellowish, opaque, head with the frons, pronotum and base of the scutellum, most of the prosternum, as well as anterior and middle legs, light brown; head anteriorly rounded, on each side slightly punctured, carina strongly marked, not reaching posterior margin; pronotum slightly foveolated, anterior part quite elevated, posterior margin deeply and angularly grooved; scutellum strongly punctured and finely striated laterally; apex of the tegmina rounded; wings hyaline; dorsal and ventral abdomen light brown, rarely darken; posterior basal spine of the tibia reduced. Body length: 6 ½ - 7 mm; tegmina: 7-9 mm; pronotum width: 2 ½ - 3 mm.

Remarks: All the specimens originally described by Berg (1879) as belonging to Tomaspis Amyot & Serville and synonymized with Cercopis terrea Germar by Berg (1883: 239), are considered here as lectotype and paralectotypes (ICZN, art. 74.1.1). These specimens were missing in the entomological collection of MLP labelled as “typus”.

Lectotype 5774/1 lacks both prothoracic legs and the mesothoracic right leg. The paralectotype 5774/2 lacks left forewing. Paralectotype 5774/3 lacks both prothoracic and mesothoracic left legs, both metathoracic legs and right forewing; the left forewing is glued to a piece of card, and the genitalia dissected in vial with glycerine.
