Grados, Juan, 2024, Beyond appearances: the genus Ernassa Walker, 1856 (Lepidoptera, Erebidae, Arctiinae, Phaegopterina) and the description of eight new species, Zootaxa 5493 (4), pp. 301-327 : 318-319

Ernassa harveyi sp. nov.

( Figs. 51–56 )

Diagnosis: Similar to E. markpacei sp. nov., from which it differs mainly by the shape of the valva. Ventrally, valva is shorter and truncated towards the dorsal process, while in E. markpacei sp. nov., it is elongate and oblique towards the dorsal process; lateral view, the dorsal process is longer, very thin, with an acute tip and curved, while in E. markpacei sp. nov., it is wide and strongly curved.

Tegumen with narrow sides, anterior margin shaped as an inverted “ V ”. Uncus base wider than the distal part of the tegumen; near its base, two lateral processes, sclerotized, “˩”-shaped, curved, with abundant long and thick bristles at their base; distal part short, pointed and hook-shaped at its end, a concave notch on its ventral part. Saccus absent.Valva. Lateral view: wide and quadrangular; ventral process elongate, membranous, with the presence of thick setae on the ventral margin; dorsal process sclerotized, elongate, thin, curved, acute distally. Ventral view: wide and quadrangular; slightly concave in its medial part, truncated towards the dorsal process; with an internal invagination, with abundant setae; dorsal processes directed mesally. Juxta sclerotized, pentagonal; a membranous area at the anterior margin, small and digitiform; and markedly concave at the posterior margin. Transtilla sclerotized, elongate, pointed towards the posterior part. Adeagus elongate and sinusoid; coecum penis elongate; vesica short, membranous, an elongate dorsal process and a digitiform ventral process; with minute spicules at the dorsal area.

Female. Unknown.
