Polyphyly of Lichen-cryptic Dagger Moths: synonymy of Agriopodes Hampson and description of a new basal acronictine genus, Chloronycta, gen. n. (Lepidoptera, Noctuidae).

Schmidt BC, Wagner DL, Zacharczenko BV, Zahiri R, Anweiler GG - Zookeys (2014)

Bottom Line: The immature stages of Chloronycta tybo comb. n. are described and illustrated for the first time.Although previously treated as a valid species, we show that Agriopodes geminata (Smith) represents the northern terminus of clinal variation in wing pattern of A. fallax and synonymize A. geminata under A. fallax (syn. n.).The history and identity of Agriopodes corticosa (Boisduval), a nomen dubium, is discussed.

ABSTRACT
The taxonomic composition and systematic position of Agriopodes Hampson is examined through an integrated approach using adult and larval morphology, biology, and molecular sequence data. The type-species of Agriopodes, Moma fallax Herrich-Schäffer is shown to be derived within the Acronicta grisea Walker species-group; accordingly, Agriopodes is relegated to synonymy under Acronicta Ochsenheimer, syn. n. (Acronictinae). Additionally, molecular markers and morphology show that Agriopodes is not monophyletic: Agriopodes tybo (Barnes) is not closely related to A. fallax nor to Acronicta, and is transferred to a new genus, Chloronycta Schmidt & Anweiler, gen. n. The immature stages of Chloronycta tybo comb. n. are described and illustrated for the first time. Although previously treated as a valid species, we show that Agriopodes geminata (Smith) represents the northern terminus of clinal variation in wing pattern of A. fallax and synonymize A. geminata under A. fallax (syn. n.). The history and identity of Agriopodes corticosa (Boisduval), a nomen dubium, is discussed.

Chloronycta tybo (Cave Creek Canyon, AZ) and Polygrammate hebraeicum (Cosby, TN) larvae. 17Chloronycta tybo early instar 18Chloronycta tybo penultimate instar 19Chloronycta tybo ultimate instar 20Polygrammate hebraeicum ultimate instar. In addition to overall resemblance, note similarities in dorsal pattern elements, as well as head allometry, colouration, and luster (particularly between penultimate instar of Chloronycta tybo and ultimate instar Polygrammate hebraeicum).

Mentions: The first two larval instars (Fig. 17) are leaf skeletonizers that remove patches of leaf tissue from the lower leaf surface. Middle (Fig. 18) and late instars feed from a leaf edge, always from the underside of a blade.
