Anaches yitingi Holzschuh & Lin, 2013: 154 , fig. 10.

Anaches yitingi: Lin, 2015 , 256, 2 figs.; Lin & Yang, 2019: 362; Danilevsky, 2020: 449; Lin & Lazarev, 2021: 74.

Male terminalia ( Figs. 14–15 ). Tegmen length about 2.0 mm; lateral lobes rather straightly tapered from middle to narrowly rounded apices, each about 0.4 mm long and 0.2 mm wide; median lobe plus median struts slightly curved, slightly longer than tegmen in length; median struts shorter than half of whole median lobe in length; apex of ventral plate strongly projected ( Fig. 15a ); median foramen elongate; internal sac with 2 hook-shaped sclerites ( Figs. 15b, 15c ). Tergite VIII ( Figs. 14a & 14c ) trapezoidal, apex slightly emarginated with round angles, provided with medium long setae along apical and lateral sides.

Diagnosis. This species is mostly similar to A. albaninus (Gressitt, 1942) , but can be easily distinguished from it by the following features: the whitish band more oblique; the anterior margins of the whitish bands “U”-shaped, instead of slightly oblique line; the sexual patches on sternite IV closer to each other ( Figs. 10a, 10b ), instead of well separated ( Figs. 11a, 11b ); the apex of tergite VIII emarginated ( Figs. 14a, 14c ), instead of rounded ( Figs. 16a, 16c ); the apex of ventral plate of median lobe projected ( Fig. 15a ), instead of pointed ( Fig. 17a ).

Type specimens examined. 1 ♂, 1 ♀, paratypes, Taiwan, Pingtung County, Mt. Dahan , 2007-V-26, leg. Wenhsin Lin ( IZCAS, IOZ (E) 1905283–84) .

Distribution. China: Taiwan.
