Pachyprotasis xibei Zhong & Wei, 2013: 849 , 852–854, fig. 852. ♂, type locality: Mt. Liupan, Fengtai (35°23′N, 106°18′E, alt. 1945 m), Ningxia, China.

Distribution. China (Ningxia and Qinghai) ( Fig. 127 View FIGURE 127 ).

Material examined. Holotype: Ningxia: ♂, Fengtai, Mt. Liupan (35°23′N, 106°18′E, 1945 m), 24.05.2008, Fei Liu leg.; Paratypes: 3 ♂, Fengtai, Mt. Liupan (35°23′N, 106°18′E, 2133– 2050 m), 26– 28.05.2008, Fei Liu leg.; Qinghai: 1 ♂, Xiewuzhen, Chengduo (33°07′ N, 97°2′ E, 3800 m), 26.06.2009, Zejian Li leg.

Discussion. This species is similar to the male of P. maculopleurita and may be distinguished as follows ( P. maculopleurita in parentheses): body length 9.5 mm (body length 5.5–6.0 mm); labrum and clypeus completely white (labrum and clypeus black); mesepisternum medially white (mesepisternum medially black); all sterna completely white (all sterna only posteriorly with white). It is also similar to P. fulvocoxis and may be distinguished as follows ( P. fulvocoxis in parentheses): median mesoscutal lobe with lateral part anteriorly white, apex without white (median mesoscutal lobe with lateral part completely black, apex with a white arrow-shaped spot); mesocutellum black, medially with two separate white spots, mesoscutellar appendage and metascutellum completely black (mesocutellum, mesoscutellar appendage and metascutellum completely white); lower part of mesepisternum with two large separate white spots, medial of mesepisternum white (mesepisternum completely black); laterally deflexed parts of all terga and all sterna completely white (laterally deflexed parts of terga with outer margins white, all sterna posteriorly with white); hind coxa without brown (hind coxa dorsally with brown). Except for the gonoforceps and penis valve, reliable morphological differences between these three species were not found.
