Tettigonia dubia nomen nudum Berg, 1884: 162 . Tettigonia platensis Berg, 1884: 162 . Ciminius platensis Young, 1977: 593 . Diagnosis. Coloration pale-yellow (Figs 8 A – C , 28 G, H ). Aedeagus (Fig. 8 G, H ) bearing from two to three large teeth on median third of ventral margin, apex expanded, broadly rounded, forming a hood-like structure. Paraphysis (Fig. 8 I ) almost rectilinear in lateral view, directed posterodorsally, apex acute; in dorsal view (Fig. 8 J ), broad at base, strongly narrowing towards apex. Description. Measurements : Total length: males (n = 20) 4.0– 4.6 mm , females (n = 20) 4.5–5.5 mm . — Crown : (Figs 8 A , 28 G ), in dorsal view, slightly produced, anterior margin from broadly rounded to subtriangular; median length of crown from 3 / 8 to 1 / 2 of intraocular width, and about 1 / 4 of transocular width. Pronotum width slightly greater than transocular width. Ocelli aligned to imaginary line between anterior eye angles. Other features as in generic description. — Coloration : Overall coloration pale-yellow (Figs 8 A – C , 28 G, H ), as described for C. albolineatus . — Male terminalia : Pygofer (Fig. 8 D ), in lateral view, posterior margin from broadly to narrowly rounded. Subgenital plate (Fig. 8 D ), in lateral view, slightly exceeding posteriorly half-length of pygofer. Valve (Fig. 8 E ), in ventral view, anterior and posterior margins subparallel; lateral margins narrowly rounded anteriorly. Style (Fig. 8 F ), in dorsal view, without preapical lobe. Aedeagus (Fig. 8 G, H ), in lateral view, shaft expanded on basal half, ventral margin bearing two or three large teeth medially, apical portion expanded, apex rounded, forming a hood-like structure. Paraphysis (Fig. 8 I, J ), in lateral view, directed posterodorsally, rectilinear, dorsal and ventral margins subparallel, not attaining pygofer apical third, apex acute. Other features as in generic description. — Female terminalia : Sternite VII (Fig. 9 A – C ), in ventral view, 1.6 × wider than long, posterior margin with a slight median lobe. Valvula II (Fig. 9 F – H ) blade with 12 continuous triangular serrated teeth, with a distinct gap in anterior margin of teeth. Other features (Fig. 9 D, E, I, J ) as in generic description.

Remarks. Ciminius platensis is a common species collected with sweeping net in open field grasses, and along with Ciminius autumnalis sp. nov. and C. sidanus , do not present male black specimens known. Ciminius platensis can be differentiated from the latter securely due to the aedeagus with few and large teeth ventrally and paraphysis rectilinear and short.
