Athetis eupsilioides Han & Kononenko , sp. n.

( Figs. 5, 6 , 21 , 33 )

Type material. Holotype: China: [Prov. Zhejiang], male, " Ost Tien-mu-shan, Prov. Chekiang, 3.iv.1931 " (H. Höne), genit. prep. ZFMK 1717 . Paratypes: 1 female, same locality and data ( ZFMK), genit. prep. ZFMK 1716 ; 2 females, Prov. Guangdong, Nanling Mts. , 23.xi.2003 and 11–14.iii.2004, M. Wang leg. ( SCAU) ; 1 female, Autonomic reg. Guangxi, Mt. Maoershan , 1.iii.2003, M. Wang leg., genit. prep. HHL-1969-2, HHL-1970-2, HHL- 1979-2 2 ( SCAU) . 1 male, China, leg. Sinyaev (coll. Nekrasov, ZISP). The holotype and one paratype are deposited in the collection of ZFMK , three paratypes are deposited in the collection SCAU , one paratype in the collection ZISP .

Diagnosis. The species differs from its relatives by a reniform which resembles those in species of the genus Eupsilia , Xylenini . The reniform consists of small white-yellowish, slightly triangular spots in discal veins of forewing surrounded with two white dots basally and apically. Some specimens of A. cinerascens have a similar reniform, but they differ by better expressed medial shade. In the male genitalia, A. eupsilioides differs by characteristic structure of valva, which is with a cut from apex to ventral margin, having strong bifurcate harpe, and strong digitus. Vesica curved under straight angle, arming with strong spine-like and row of pin-like cornuti.

Description. External appearance ( Fig. 5, 6 ). Wingspan 34–35 mm. Male antennae slightly fasciculate, ciliated; palps pressed, dark brown laterally, yellowish ventrally, 3rd segment short, about half length of 2nd; eyes surrounded with brown lashes; head and thorax covered with brown hair-like scales, head with erected hairs. Ground color of forewing brown; basal line as black streak in costal field; subbasal line thin, dark, broken; orbicular as dark dot; reniform as yellowish central spot surrounded medially, caudally and marginally by three white dots on dark background; postmedial line thin, dark; subterminal line diffused; cilia dark brown with whitish borderline. Hindwing grey-brown with traceable discal spot, cilia yellowish grey. Male genitalia. ( Fig. 21 ). Abdominal hair brushes missing. Uncus completely reduced; tegumen high, with wide lobes, well sclerotised, vinculum V-shaped; juxta leaf-shaped, with medial bar and long handle like extension; valva narrow, elongated with parallel margins, in distal third curved dorsally; distal margin of valva between apex of costa and digitus concave cut, membranous; apex of costa forms rounded cucullus covered by thin dense hairs; digitus as strong pointed extension; harpe situated at distal fourth of valva, strong, elongated, bifurcated with apices acute, dorsal apex much longer and acute than ventral one. Aedeagus large, about equal to valva, its distal part strongly sclerotised, carina short; vesica curved under straight angle, arming with row of 10–12 strong, long spine-like cornuti basally and moderate pin like cornuti from medial to apical part. Female genitalia. ( Fig. 33 ). Ovipositor short, weak; papillae anales short, quadrangular, apophyses anteriores rather moderate, apophyses posteriores about 2 times longer than anteriores ones; ostium split-like, antrum formed by large quadrangular extremely large antevaginal plate, which is high, rounded apically, with deep narrow split centrally; ductus bursae short, wide, folded in connection with antrum, extended to join with bursa, enveloped bursa from lateral and dorsal sides; bursa short, deposited horizontally, with large sclerotised and wrinkled cervix and membranous corpus bursae.

Etymology. The species name “ eupsilioides ” refers to external similarity of the species to the genus Eupsilia Hübner, [1821] 1816 ( Noctuinae , Xylenini ).

Distribution. East China (Prov. Zhejiang, Guangdong, Autonomic reg. Guangxi). The moths fly from March to April.
