Han, H. L. & Kononenko, V. S., 2017, Two new species of the family Noctuidae from China (Lepidoptera, Noctuidae), Zootaxa 4338 (2), pp. 385-392 : 386-387

Victrix acronictoides sp. n.

( Figs 1–4 , 6 )

Type material. Holotype: male, China, Prov. Yunnan, Tengchong, Guangpojiao , 1.v.2013, Hui Lin Han leg.; genitalia slide HHL-3815-1 (coll. NEFU) . Paratypes: 3 males with same data (coll. NEFU) .

Diagnosis. Externally the new species resembling species of the subfamily Acronictinae , especially the Craniophora Snellen spp. Compared with other known Victrix species [ V. confucii ( Figs 5 , 7 ) is illustrated here for the comparison] it differs by more robust habitués, narrower shape of wings and wing pattern unusual for Victrix spp., namely by presence of the prominent basal streak, peculiar basal silver-white patch, whitish spot in the medial area and clear Y -like mark in the costal area formed by medial line. The male genitalia by shape of valva and presence of harpe are more or less typical for Victrix spp., subgenus Rasihia .

Description. Adult ( Figs 1–4 ). Wingspan 29–31 mm. Male antennae simple, filiform; labial palps short, 3rd segment about half of 2nd, cowered with white scales, 2nd segment black; proboscis developed; eyes normal, rounded; head covered with ochre-greenish scales; frons convex, bearing little protuberance ( Figs 3, 4 ); thorax covered with ochre-green and brown scales in mixture, patagia and tegulae bordered with dark-brown. Ground colour of forewing brownish-grey with pale whitish in outer part of wing and with ochre-green suffusion in basal, subbasal and costal and outer parts of wing; main elements of wing pattern black or white, contrasting with ground colour. Basal streak distinct, black, extends from base of wing to antemedial line between veins Cu and A; clear silver-white patch lied above basal streak; antemedial line twin, whitish inside, tinged by black outside; medial field basically brownish-grey, with ochre-greenish filling from costal area to medial part; orbicular large, quadrangular, formed with thin bordered line, large whitish lies below outside of reniform; medial line black, distinct, forms y -like mark in costal field; part of medial field behind medial line ochre-greenish in inner part and whitish-grey in outer part, define by black mark in costal area; reniform indistinct; postmedial line blackish, slightly waved; subterminal field greyish with white, in costal area with dark greenish with black bordering subterminal mark; subterminal line diffused, interrupted, greyish with white outer bordering; terminal field with distinct blackish terminal and subtornal marks; terminal line blackish, interrupted; cilia speckled, white between veins and ochre-grey opposite veins. Hindwing pale greyish-brown in inner part, gradually darker grey in outer part; discal spot and medial fascia traceable; cilia whitish and ochre-grey opposite veins. Male genitalia. ( Fig. 6 ). Uncus cylindrical, straight, relatively short; tegumen wide, shorter than vinculum; transtilla not expressed as in other Victrix species; juxta deltoid, extended apically; valva rather wide basally, gradually constricted apically; sacculus broad, with setose dorsal patch; clasper well expressed, sclerotised transversal rib-like; harpe rather long, flat, positioned distally, along costa, thin, pointed; valva apex acute, pointed. Aedeagus moderate in length, slightly curved; carina patch of with small plate-like cornuti and little row of join cornuti; vesica everted perpendicularly (t - like) to aedeagus tube, broadly quadrangular in basal part, tubular in apical part, bearing three small diverticula, two of them armed with small flat cornuti.

Female unknown.

Distribution. China, Province Yunnan, Guangpojiao. Adult collected in May.

Etymology. The species name refers to external similarity of the new species to species of the subfamily Acronictinae .
