Material examined. Type-series: Lectotype of Valeria euplexina (herewith designated): male with labels: “Likiang (China), Provinz Nord-Yuennan, 19.9.1935. H. Höne / Valeria euplexina male Draudt / Holotype Valeria euplexina male Draudt / gen. prep. Hreblay N: 10016” (ZFMK); paralectoype of Valeria euplexina: female with labels: “Likiang (China), Provinz Nord-Yuennan, 14.9.1935. H. Höne / Allotype Valeria euplexina female Draudt / gen. prep. Hreblay N: 10017 female” (ZFMK). Other material examined: 1 male, 1 female, China, W. Sichuan, road Dawe/Lushan, Xiling Xue Shan Mt. H-2500 m, 19.ix.2011, N30°50.620′, E102°45.221′, A. Floriani leg., Genit. prep. GB12188, GB12189.
Diagnosis. Adult (Figs. 19–21). Wingspan 36–38 mm. Atrovirensis euplexina externally looks similar to A. yoshimotoi and A. miraculosus, but differs from the first species by narrower and longer shape of forewing with prominently oblique outer margin, and from the second relative by darker mossy-green pale elements of wing pattern. The markings of the wing pattern are similar to A. yoshimotoi and A. miraculosus. Ground colour of forewing blackish with yellowish-green dusting; basal, subbasal and subterminal fields, orbicular and reniform mossy-green; transversal lines black, outlined with white; claviform and medial shadow traceable; terminal field as in A. miraculosus, but black spots are smaller, terminal line disrupted into a row of black narrow streaks; cilia mottled. Hindwing yellowish-grey, with traceable discal spot and mottled cilia. Male genitalia (Fig. 35). In the male genitalia all structures heavily sclerotised. Uncus moderate long and wide, somewhat extended subapically; tegumen broad, without extended peniculus; juxta large, trapezoid, plate-like, with deep cut in apical part; valva moderate wide, with well-expressed neck of cucullus; sacculus with short, vestigial lateral extension; strong clasper, positioned transversally, bearing strong stout apically slightly hooked harpe; neck of cucullus rather long; cucullus moderate, rounded, armed with 1–2 row(s) of weak coronal setae. Aedeagus rather short, but stout, with broad, sclerotised carina; vesica short, rather broad, with large medial diverticula armed with short cutter-like cornutus; four strong cornuti on broad base lie in subbasal part of vesica and 5 small teeth in basal part. Female genitalia (Fig. 48) The female genitalia differ from those of other congeners by large flattened-conical ovipositor, which is somewhat constricted and pointed apically; papillae anales about 2 times larger than in other species, except A. miraculosus (Fig. 47), weakly sclerotised, shallow cup-like antrum with sclerotised lateral angles, short and broad, scobinate, ribbed and slightly sclerotised ductus bursae and large, sack-like corpus bursae.
Distribution. China (Prov. Yunnan, Prov. Sichuan).
Note. The species has been described by ‘wenige Paare von Li-Kiang, 14 bis 19.ix.35” [one pair from Likiang 14 and 19.ix.35] (Draudt 1950). The specimens with corresponding data, male, collected at 19.ix and female at 14.ix.1935 are marked in the collection of ZFMK as “Holotype” and “Allotype”, however the types were not indicated in the original description as well as for other species described by Draudt (1950). Therefore, the male specimen labelled as “Holotype” in fact is the lectotype of Valeria euplexina Draudt, 1950; the female marked as “Allotypus” is the paralectotype. Although the specimens of A. euplexina from Sichuan differ externally from the types described from Yunnan, the male and female genitalia structure of those are identical with lecto- and paralectotypes.
It worth to note, that Draudt (1950) described two different species with same name “ euplexina ” in genera Eumichtis and Valeria in same publication, on same page with imago illustration on same plate, what created some confusion for lepidopterists discussing these taxa.
The Eumichtis euplexina Draudt, 1950: 67, Pl. 5: 1, 2 has been revised by Hreblay & Ronkay (1997, 1998); the lectotype has been designated and the species has been placed to the genus Oroplexia Hampson, 1908 (Noctuidae, Xyleninae, Phlogophorini) (Hreblay et al. 1998).
The Valeria euplexina Draudt, 1950: 67, Pl. 5: 4 is revised hereby for the first time. By our opinion, based on analysis of morphological characters, V. e u pl ex i na could be considered as a member of the genus Atrovirensis (Noctuidae, Xyleninae, Apameini).
