Genus Planovalvata Dubatolov & Kishida, 2012

Planovalvata Dubatolov & Kishida in Dubatolov, Kishida & Wang , Tinea 22 (1): 39. Type species: Planovalvata confusa Volynkin, Dubatolov & Kishida , sp. nov. (= Stigmatophora roseivena sensu Dubatolov et al. (2012) , neC Hampson (1894)).

Taxonomic note. In the original description, Dubatolov & Kishida (Dubatolov et al. 2012) attributed the genus to "the series of Miltochrista -like genera" ( Asura / Miltochrista complex by Holloway 2001), but according to the male genitalia structure (entire distal section of valve with a longitudinal zone of costally directed strong setae), it is related to the genus Eugoa Walker, [1858] and not to the Asura / Miltochrista complex. At present the genus Eugoa includes several groups of species with significantly different genital structures and some of them probably could be erected into separated genera. The generic/subgeneric structure of this group will be revised later by the authors.

Diagnosis. Small moths with yellow forewing ground color and pattern consisting of red strokes on veins and along the costal margin. In the male genitalia, Planovalvata has the following apomorphic differences from the typical Eugoa (the type species Eugoa aequalis (Walker, [1858]) was illustrated by Holloway (2001) and Durante (2012)): 1) uncus is long, narrow and laterally flattened (whereas in Eugoa the uncus is short, dorso-ventrally spatula-like broadened); 2) tegumen without paratergal sclerites and dentate penicular lobes (whereas in Eugoa s. str. the tegumen with rounded paratergal sclerites and large irregularly dentate penicular lobes); 3) vinculum is very short (whereas in Eugoa the vinculum is longer); 4) distal part of the costal margin of valve is irregularly dentate (whereas in Eugoa the costal margin of valve is smooth). Female unknown.
