Translation:

Opaque, dorsally yellowish, tegmina with a dark brown median band, broader toward apex thickened anteriorly, ornamented; posterior legs yellowish, ventral surface of the abdomen darkened with margins red; rounded head, vertex punctate on each side, a strongly transversal groove at the middle and in front of the ocelli, convex frons a longitudinal median carina, with a well-marked carina, striated laterally. Pronotum with anterior surface foveolate and posteriorly punctate. Scutellum acuminated, printed at the middle portion; tegmina punctuate, apically slightly areolate, with a median brownish-darkned band, sometime insconspicuous. Wings hyaline, veins darkened; sometime dorsal surface of the abdomen red; terminal portion of posterior tibiae spine darkened-black. Long. corp. 8-10 mm, tegm. 11-13 mm; lat. Pron. 3-3 ½ mm”.

Remarks: Both the specimens were labelled as “typus” by Berg (1883), treated as syntypes by Carvalho & Webb (2005: 107) and are considered here as lectotype and paralectotype (ICZN, art. 74.1.1). This species was treated as “species of uncertain position” by Carvalho & Webb (2005: 107).

Lectotype 1734/1 has the genitalia dissected in vial with glycerine and lacks both mesothoracic legs. Paralectotype 1734/2 lacks left forewing and prothoracic and metathoracic left legs.
