Type species: dumerillana Duponchel = angustiorana Haworth
DIAGNOSIS
External characters:
Venation:
venation Batodes angustiorana
Forewing: R 4-R 5 stalked to middle; CuP preserved in most terminal part of wing.
Hindwing: R-M 1 stalked to middle; M 3 -CuA 1 stalked.
Forewing shape and markings:
Batodes angustiorana male 2; Batodes angustiorana female 2
Moths fairly small; costa gradually arced, termen convex. Males with short costal fold.
Sexual dimorphism:
Males are smaller than females, they have dentate-ciliate antennae and the forewing has a short costal fold.
Genitalia:
Male:
male genitalia B. angustiorana
Uncus strong. Transtilla broad, folded medially; brachiola-like shallow pocket in outer portion of valva externally; costa of valva well-developed; aedeagus with three short cornuti in vesica; coecum penis well-developed.
Female:
female gen. B. angustiorana
Sterigma with well developed antevaginal portion and cup-shaped part; antrum short, with internal sclerite; ductus seminalis subterminal, situated dorsally; signum dagger-shaped with well developed basal lobes.
Taxonomic note:
The genus has also often been referred to as Ditula. However, according to Razowski, 1987a, Ditula must be regarded as a synonym of Eudemis (Olethreutinae), and synonymization of Batodes with Ditula was therefore incorrect.
Early stages:
Eggs of Batodes angustiorana are pale yellow and are deposited in a scale-like batch. Larvae of this species are pale yellowish green to brownish green or greyish green. Swatschek, 1958, provides the following diagnosis based on chaetotaxy: crochets on the abdominal prolegs small and almost equal in length anteriorly and bigger and clearly arranged biordinally posteriorly. The second stemma equidistant from first and third. Spiracle on abdominal segments 2-7 not bigger than basal ring of seta SD1. Seta D1 equidistant from SD1 and D2 on the ninth abdominal segment, the pinacula being clearly separated.
Biology:
Larvae are polyphagous on both deciduous trees and conifers.
Batodes angustiorana is an univoltine species; young larvae hibernate.
Distribution:
Western part of the Palaearctic Region except for Asia Minor; Nearctic Region.
