Athetis linzhi Han & Kononenko , sp. n.

( Figs. 8 , 23 , 34 )

Type material. Holotype: male, China, Xizang, Linzhi , 1–20.vii.2009, Z. H. Pan leg., genit. prep. HHL-1976-1 . Paratype: female with same data as holotype, genit. prep. HHL-1978-2 (coll. NEFU). The holotype and paratypes are deposited in the collection of NEFU .

Diagnosis. This species shows magenta-brown coloration similar to Athetis suffusa Yoshimoto, 1994 , described from Nepal ( Yoshimoto 1994), but differs from it by weakly expressed wing pattern. In male genitalia it differs from A. suffusa by less serrate harpe, short rounded pollex and shape and arming of vesica, which is Tshaped, armed by small to moderate cornuti of about equal length, while in A. suffusa vesica not t-shaped and armed by long thin cornuti. Female genitalia of this and the next species show a relation to A. fasciata group by characteristic shape of bursa and by the presence of signum formed by row of small spines.

Description. External appearance ( Fig. 8 ). Wingspan 34–35 mm. Male antennae filiform. Palps pressed, brown, their 3rd segment very short, about half length of 2nd; eyes surrounded with lashes. Head and thorax covered by magenta-brown hairs and hair-like scales. Ground color of forewing magenta-brown with intrusion of black scales; basal line marked in costal area; antemedial line thin, black, hardly traceable; orbicular as black dot; reniform dark brown, surrounded with pale reddish brown scales; medial field shadowed; postmedial line weak, thin, represented as twin row of black dots; subterminal line dark, straight, indistinct; terminal field brown; veins in subterminal and terminal fields suffused with dark grey; cilia grey, basally pale. Hindwing grey, with darker veins, discal spot traceable; cilia grey, with pale borderline. Male genitalia. ( Fig. 23 ). Abdominal hair brushes present. Uncus vestigial, small, apically abrupt; tegumen twice higher than vinculum; wide, with well developed lobes, vinculum V-shaped; juxta leaf-shaped; valva relatively broad, elongated, with parallel margins, distally curved dorsally, clavus not present; cucullus rounded, covered by dense thin hairs; sacculus long, clasper elongate, plate-like; harpe situated at distal third of valva, rather strong, short and broad, serrate along distal margin, pointed at apex; digitus relatively large and broad, ventrally extending beyond valva. Aedeagus slightly curved and extended apically; vesica tubular, T-shaped, with rather long basal diverticulum, bearing numerous spine-like cornuti of approximately equal length, and six somewhat larger cornuti on top of diverticulum. Female genitalia. ( Fig. 34 ). Ovipositor rather long, papillae anales weak, elongated, apophyses anteriores and posteriores long, thin, almost equal in length; ostium split-like, antrum sclerotised, cup-like, with medial fold; ductus bursa sclerotised, folded in joining with antrum; corpus bursae rounded, bearing ribbon-like signum formed by small spines; appendix bursae rather large, apically transformed to narrow tube, positioned posteriorly.

Etymology. The species name “ linzhi ” refers to the type-locality of the species, Linzhi village in Autonomous Region Xizang of China.

Distribution. South West China (Autonomous Region Xizang). The moths fly in July.
