Type species.

Dickyyuella argentinensis Kang & Sharkey, sp. nov.

Diagnosis.

Body relatively small compared to members of the other cardiochiline genera, with strong sculpture, especially on mesosoma. Antenna thick (Fig. 1 A). Eyes bare (Fig. 1 B). Occipital carina well developed dorsally, absent ventrally (Fig. 1 E). Most of head with weak microsculpture. Median ocellus surrounded medially and laterally by a smooth, curved ridge. Pronotum bilobed anteriorly with a transverse plate dorsally. Notauli deeply impressed and entirely costate (Fig. 1 E). Median lobe of mesoscutum bilobed. Scutellar sulcus deep with a median carina (Fig. 1 E). Scutellum smooth and flat. Postscutellar depression absent (Fig. 1 E). Epicnemial carina strong and complete (Fig. 1 B). Precoxal sulcus well defined with ~ 5 costulae (Fig. 1 B). Propodeum rugose with a large, well-defined median areola. Apical abscissa of RS entirely nebulous and almost straight, very slightly curved posteriorly (Fig. 1 C). (RS + M) b about 3 × longer than m-cu vein (Fig. 1 C). 1 M about 3 × longer than m-cu vein; lacking distinct claval lobe. Veins M + Cu and M about equal in length. Hind basitarsomere swollen (Fig. 1 A). Tarsal claws rather large with pectinate base (Fig. 1 D). Spiracle of T 1 on membranous laterotergite (Fig. 1 B). T 1 wide with carinate lateral margins; medial area of T 1 with an inverse Y-shaped depression (Fig. 1 E).

Notes.

The members of Dickyyuella Kang & Sharkey, gen. nov. will run to couplet 1 in the key to the world genera by Dangerfield et al. (1999), but it can be easily distinguished from members of Heteropteron and Neocardiochiles by the size, well-developed occipital carina, deep and broad notauli, large median areola on propodeum, and rugose propodeum.
