Material examined. Holotype, male, Hanasi Lake, Xinjiang, China ( 47°14.64'N, 87°12.41'E; elev. 1 374 m), 14 August 1997, coll. Daochao Jin, slide number XJ-IV-1997081401. Paratypes: 3 males, slide numbers XJ-IV-1997081402, XJ-IV- 1997081403 and XJ-IV-1997081404, same data as holotype GoogleMaps .

Etymology. “ pseudo- ” means “not real” or “imitated”. The new species is named after the species Lebertia ( Lebertia) maglioi Thor, 1907 (Thor, 1907) which is similar to the new species.

Habitat. Stream.

Distribution. Palaearctic Region ( China ( Xinjiang)).

Remarks. This new species is similar to Lebertia ( Lebertia) alia Semenchenko & Tuzovskij, 2010 from Russia, and L. ( L.) maglioi Thor, 1907 from Germany, respectively. The new species is similar with L. alia by the ventral seta insertions divided the ventral margins of P-4 into 1:1:2 and the similar length of suture lines (Cx-I/II ML ratio 0.96–1.17 in L. alia). But they can be distinguished by the following: 1) Integument of L. alia with fine striation and porosity while the new species with sculptured surface; 2) Cx-IV of L. alia with nearly right angled posteromedial edges while the new species with obtuse angled posteromedial edges ( Fig. 16 View Figures 16–17 ); 3) Ventrodistal seta longer than ventral margin of P- 2 in L. alia while the new species not ( Fig. 18 View Figures 18–23 ); 4) III-L-5 and IV-L-5 each with 1 short swimming seta in L. alia but the swimming seta of the new species reduced completely ( Figs 22–23 View Figures 18–23 ); 5) Each genital flap in males with 18–24 medial and 6–7 lateral setae in L. alia while the new species bearing 4 medial setae and without lateral setae on each genital flap ( Fig. 21 View Figures 18–23 ). The data of L. alia from Semenchenko & Tuzovskij (2010).

The new species is also very similar to L. maglioi in these points: 1) P-4 with maximum height in basal part, distal part narrow; 2) The suture lines similar in length (Cx-I/II ML ratio 0.9–1.1 in L. maglioi); 3) Distance between dorsal setae of P-3 <20. But they can be distinguished by the following: 1) Integument of L. maglioi smooth, while the new species with sculptured surface; 2) Cx-IV of L. maglioi with nearly right angled posteromedial edges while the new species with obtuse angled posteromedial edges ( Fig. 16 View Figures 16–17 ); 3) III-L-5 with 1 and IV-L-5 with 2 swimming setae in L. maglioi while no swimming seta in the new species ( Figs 22–23 View Figures 18–23 ); 4) IV-L-6 of L. maglioi with 2 small ventral setae, but IV-L-6 of the new species without ventral seta ( Fig. 23 View Figures 18–23 ); 5) IV-L-5 of L. maglioi with 3-4 ventral setae and 2 ventrodistal setae, but in L. pseudomaglioi with 2 ventral setae and 1 ventrodistal seta ( Fig. 23 View Figures 18–23 ). The data of L. maglioi from Gerecke (2009).
