( Figs. 6 View Figs , 14 View Figs )

Material examined. CHINA: SHAANXI PROVINCE: Qingling Shan mts, 6 km S Xunyangba, ca. 33°28′ N, 108°30′ E, 18.–20.v.2005, O. Nakládal leg., on the first mountain ridge S of Xunyangba, wet close valley near the stream, secondary mixed forest, unbaited pitfall traps, 1 ♀ ( JRPC).

Note. The single female specimen is subteneral and although it probably represents an undescribed species, it is not formally named here until a conspecific male becomes available. However, we provide here a brief description to facilitate its association with other specimens in the future.

Diagnostic description. Measurements: TBL 6.6 mm, PMW/PML 1.64, PMW/PBW 1.14, EL/EW 1.22, EW/PMW 1.55.

Body large in size, robust and only weakly vaulted ( Fig. 6 View Figs ), habitually similar to A. turkestanicum ( Semenov, 1893) . Dorsum light brown, pronotal disc with narrow, dark brown medial spot; antennae, mouthparts and legs uniformly light brown ( Fig. 6 View Figs ). Dorsal surface lustrous, head and pronotum without microsculpture, elytra with fine, slightly transverse microsculpture. Pronotum and elytra with scattered short erect setae.

Pronotum widest at half of length; anterior margin distinctly emarginate; lateral margin finely bordered, weakly explanate; sides moderately raised and weakly sinuate posteriorly ( Fig. 6 View Figs ); base wide, without impressions. Disc impunctate, lateral and posterior areas with scarce strong punctures.

Elytra broadly oval, apical part elongate. Each elytron with nine regular striae, stria 3 with ca. 58 medium-sized punctures; interstriae flat; elytron with narrow epipleural keel; lateral margin smooth, without serration. Hind wings fully developed.

Male. Unknown.

Female. Posterior margin of ventrite VIII regularly rounded with slight lateral sinuosity, spiculum ventrale wide, conically tapering toward weakly emarginate anterior margin, distinctly broadened latero-apical margin ( Fig. 14 View Figs ). Ovipositor with transverse, asetose valvifer; triangular, heavily sclerotized coxite bearing numerous setae; stylus modified into strongly curved, apically glabrous scrapers (similar to A. belousovi sp. nov., A. davidis , A. jelineki sp. nov., A. jinfo [see RŮŽIČKA et al. 2004: 119, Fig. 20 View Figs ], A. qinlingense and A. schawalleri ).

Distribution. This presumably new species of Apteroloma is presently known only from a single locality in the Qinling Shan mts in the Shaanxi province. It was collected together with A. potanini and A. qinlingense .
