Eccritotarsus nigro-cruciatus Stål, 1860: 57 (original description).

Eccritotarsus magnificus Distant, 1888: 82 (original description). Synonymized by Carvalho & China, 1951: 676.

Material examined. BRAZIL. Minas Gerais: 7 ♂ 1 ♀, Viçosa, 18.viii.1982 (Fiuza & Martins) ( UFVB) ; 1 ♂, Viçosa, 14.iii.1933 (E. J. Hambleton) ( UFVB) ; Rio Grande do Sul: 1 ♂, Putinga , 603 m, 29.x.2003 ( UFVB) .

Diagnosis. Body white and black with yellow areas. Head in dorsal view, antennal segments I and II, pronotum and apex of cuneus black. Propleuron with anterior area to the coxal suture yellowish. Xyphus black and yellow. Corium with transverse stripe extending to the clavus and generally to the embolium. Body length 3.73–5.00 mm. Right paramere ( Fig. 51 ) with basal process short and wide; body wide with median constriction; sensory lobe absent; apical process proximally elongate, apically sub-rectangular and transverse to the proximal part. Left paramere ( Fig. 52 ) with basal process wider towards the body; body flattened and convex, wider medially; sensory lobe absent; apical process elongate, curved and truncate at the apex.

Associated/host plants. Unknown.

Distribution. Argentina ( Carpintero & Carvalho 1993) , Brazil ( Carvalho & Afonso 1977), Ecuador ( Carvalho 1957).— Colombia (Valle del Cauca) ( Carvalho & Afonso 1977).

Comments. Specimens of E. nigrocruciatus in literature ranged 3.85–5.00 mm long ( Stål, 1860; Distant 1888, Ferreira &Henry 2011). Specimens in the present work are 3.73–3.80 mm; hence, length ranges are 3.73–5.00 mm.
