Soractellus lalianensis sp. nov. ( Figs. 1A–I , 2A–C )

Genitalia. Pygofer considerably longer than wide, with numerous stout setae ( Fig. 2A ). Valve triangular ( Fig. 2B ). Connective loop-shaped, without stem ( Fig. 2B ). Style elongate, with preapical lobe moderately developed, apophysis long and thumb-like ( Fig. 2B ). Aedeagal shaft elongate, forked at apex, with branches more than one third length of aedeagus, gradually attenuating in lateral view, gonopore at base ( Fig. 2B, C ).

Female seventh sternum tumid medially on posterior margin ( Fig. 1D ).

Type material: Holotype: ♂, PAKISTAN, Lalian City , 21 May 2016, Coll. Hassan Naveed . Paratypes: 7♂, 5♀ same data as holotype ; 12♂, 9♀, Mianwali City , 18 July 2017, Coll. Hassan Naveed .

Remarks. This species is similar to Soractellus jianfengensis but can be distinguished from the latter by the following characteristics: forewings brachypterous, aedeagal shaft with apical branches nearly 1/4 of total length, style apophysis straight and stout, and female seventh sternum tumid medially on posterior margin.
