Type species. Eutychide gertschi Bell, 1937 .

Definition. Placed in Justinia Evans, 1955 (type species Hesperia justinianus Latreille, [1824] ), this genus is not monophyletic with it, and is instead in a different subtribe (not Falgina Grishin, 2019, but Moncina A. Warren, 2008 ), being in the same clade with Niconiades Hübner, [1821] , Thoon Godman, 1900 , Joanna Evans, 1955 and Pares Grishin, 2019 among others and not showing closer relationship with any of these genera ( Fig. 13 ). Keys to J. 50.6 in Evans (1955) and is distinguished from its relatives by the following combination of characters: antennae longer than half of the costal margin, palpi gracile, last segment conical and short, mid-tibiae without spines, very short and broad uncus with lateral projection on each side, together with tegumen square-shaped in dorsal view, saccus short, the same length as uncus, unusually shaped valva: broad with a bulging costa, trapezoid in shape, harpe upturned with stout teeth at the angles, penis the same length as vinculum in lateral view and slightly narrower than tegumen in lateral view. In DNA, a combination of the following base pairs is diagnostic: aly207.4.2:A41C, aly1019.26.7:A53T, aly925.20.2:G1259A, aly15220.5.8:A772C, and aly276890.2.1:T39C.

Etymology. The name is a feminine noun in the nominative singular, given for the rhomboidal shape of valvae.

Species included. Only the type species.

Parent taxon. Subtribe Moncina A. Warren, 2008 .
