Han, H. L., Pan, Z. H. & Kononenko, V. S., 2016, A review of the genus Atrovirensis Kononenko, 2001 with description of four new species from China (Lepidoptera, Noctuidae: Xyleninae, Apameini), Zootaxa 4088 (2), pp. 201-220 : 215

( Figs 12, 13 , 31 , 44 )

Material examined: male, China, Prov. Guangdong, Huizhou City, Mt. Nankun, 18.v.2003, M.Wang leg., genit. prep. HHL-2918-1. Coll. NEFU, Harbin; 1 female, Prov. Guangdong, Mt. Nanling, 22.vi.2003, M.Wang leg., genit. prep. HHL-2909-2. Coll. SCAU, presently deposited NEFU, Harbin.

Beside the examined material on A. furcatus we found the taxon, with by our opinion is closely related, but somewhat different from A. furcatus . We avoid describing it as a new species before more material can be acquired to judge the morphological difference with A. furcatus or the molecular study can prove its specific status. The data on specimens and diagnosis are given here.

Diagnosis. Adult. ( Figs 12, 13 ). Wingspan 43–45 mm. The taxon belongs to A. sinica group. It is externally similar to its sister-species A. furcatus and the other species of the group, but can be distinguished from them by somewhat larger size (wingspan 43–45 mm), darker colouration of the forewing, mossy-green colour of pale elements of wing pattern and narrower subterminal field. Male genitalia. ( Fig. 31 ). The male genitalia of A. sp. cf. furcatus are very similar to those of A. furcatus , but differs by somewhat narrower valva, more triangular shaped cucullus, longer ventral extension of sacculus and by shape of harpe, which is thinner and longer than those in A. furcatus , knee-like curved in apical third, but not slightly furcate as in A. furcatus . Aedeagus with longer basal tube of vesica, narrower ventral extension armed with two tiny cornuti; medial diverticulum armed with stick-like cornutus shorter, but more massive compared with A. furcatus . Female genitalia. ( Fig. 44 ). Female genitalia close to A. owadai ( Fig. 41, 42 ) and A. furcatus ( Fig. 43 ), but differ by very small antrum formed by two small semicircular setose plates; ductus bursae longer than in A. owadai and thicker than in A. furcatus .

Distribution. South East China (Prov. Guangdong). The taxon is known only from its collecting sites.

Note. The male and female of this taxon (male, genit. slide HHL-2918-1 and female, HHL-2909-2) were incorrectly included to the type-series of A. owadai as paratypes (Gyulai et al. 2013).
