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.
