Genus Dozierana View in CoL gen. nov.

Type species: Thionia gibbicollis Dozier, 1931 View in CoL , by monotypy.

Etymology. The genus is named in honour of Dr. Herbert Lawrence Dozier who described the type species.

Diagnosis. Metope with only median carina distinct ( Figs 3 View Figs 1–5 , 8). Fore wings wide, not narrowing, but widely truncate apically, with wide hypocostal plate ( Figs 2 View Figs 1–5 , 6). Clavus as long as whole wing. Hind wings well developed, as long as fore wings. Mesonotum greatly elevated (hump-shaped) along median carina ( Figs 2 View Figs 1–5 , 6, mc). Hind tibiae with single lateral spine subapically.

Description. Metope wide, enlarged below eyes, with distinct median carina running from its upper margin through postclypeus; sublateral carinae very weak ( Figs 3 View Figs 1–5 , 8). Upper margin of metope concave. Metopoclypeal suture distinct. Coryphe transverse, 3 times as wide as long medially, without carina ( Figs 1 View Figs 1–5 , 7). Large ocelli present. Pronotum short, with 4 lateral carinae; anterior margin strongly convex; posterior margin strongly concave ( Fig. 7). Mesonotum 7 times as long as pronotum along midline, greatly elevated (hump-shaped) along median carina, with two lateral carinae joined with median one in shape of inverted “V” ( Figs 1 View Figs 1–5 , 6, mc, lc, 7). Tegulae large. Fore wings wide, not narrowing, but obliquely truncate apically, with wide hypocostal plate and rich cross-venation through whole wing, except subcostal area ( Figs 2 View Figs 1–5 , 6, hp). Costal vein with distinct upper keel appearing as a separate vein ( Fig. 6, uck). Basal cell large, oval. Forewing vein sequence: R 2, furcating on short distance from basal cell; M 2, furcating near mid of wing; CuA 1, running into apex of clavus ( Fig. 6, CuA ). Clavus as long as whole wing, open – Pcu + A 1 runs into apex of clavus. Pcu fusing A 1 after middle of clavus ( Figs 1 View Figs 1–5 , 6). Hind tibiae with single lateral spine subapically and 5 apical spines ( Fig. 2 View Figs 1–5 ).
