Mongoliana arcuata View in CoL sp. nov.

Gergithus triangularis View in CoL [sic!] = Mongoliana triangularis Chen, Zhang & Chang, 2014: 76 View in CoL , non Mongoliana triangularis Che, Wang & Chou, 2003: 38 View in CoL .

Diagnosis. The new species differs from M. triangularis Che, Wang et Chou by (features of M. triangularis Che, Wang et Chou in parentheses): clypeus black ( Chen et al. 2014, Fig. 2 View FIGURES 1 – 6. 1 – 3 –31E) [clypeus pale brown ( Fig. 26 View FIGURES 21 – 26. 21 – 23 )]; anal tube with apical margin convex, lateroapical angle obtuse ( Chen et al. 2014, Fig. 2 View FIGURES 1 – 6. 1 – 3 –31H) [apical margin of anal tube sinuate, lateroapical angle protruding ( Fig. 73 View FIGURES 73 – 80. 73 – 76 )]; aedeagus with pair of asymmetrical processes both arising from base ( Chen et al. 2014, Fig. 2 View FIGURES 1 – 6. 1 – 3 –31K, L) [processes symmetrical and both arising from middle ( Figs 74–76 View FIGURES 73 – 80. 73 – 76 )]; pygofer in profile with posterior margin slightly convex near middle ( Chen et al. 2014, Fig. 2 View FIGURES 1 – 6. 1 – 3 –31I) [pygofer in profile with posterior margin concave in dorsal one-third, strongly convex near middle ( Che et al. 2003, Fig. 2 View FIGURES 1 – 6. 1 – 3 B)].

Description (modified after Chen et al. ’s original description). Body brown. Frons fuscous, with yellow tubercules and numerous yellow spots. Frontoclypeal suture and clypeus black except a yellow transverse fascia at the base of clypeus.

Male terminalia. Anal tube with apical margin convex in middle, lateroapical angle obtuse. Pygofer in lateral view with posterior margin slightly convex near middle. Lateral lobes of phallobase arcuate at apex, dorsal margin serrated near apex; ventral lobe with apical margin slightly sinuate; aedeagus with paired asymmetrical processes at base. Genital style with hind margin nearly straight near middle, dorsal margin with moderate subquadrate process at middle.

Material examined. One male (holotype), China, Yunnan Province, Gaoligong Mountains National Nature Reserve, Baihualing, 8 May 2009, Zaihua Yang; two males (paratypes), same data as holotype ( IEGU, examined from images only).

Etymology. The specific epithet “ arcuata ” refers to arcuate apical margin of the anal tube.

Distribution. China (Yunnan) ( Fig. 81 View FIGURE 81 ).

Notes. Recently, Chen et al. (2014) re-described M. triangularis based on three males from Yunnan, China. Although Chen et al. (2014) misspelled Gergithus triangularis , as Gnezdilov (2015) mentioned: “There are several misprints:…….p. 76— Gergithus triangularis should be changed to Mongoliana triangularis ”. The redescriptions and figures by Chen et al. (2014) show patterns of clypeus coloration and configuration of male genitalia for the species identified by them (see Chen et al. 2014: 76, 77, Figs 2 View FIGURES 1 – 6. 1 – 3 –31) apparently differ from the holotype of M. triangularis Che, Wang et Chou (now deposited in NWAFU). We considered that it was misidentified and regard as to be a new species in the genus Mongoliana . The photographs of habitus and male genitalia of the holotype of M. triangularis Che, Wang et Chou, 2003 are provided here (see Figs 24 – 26 View FIGURES 21 – 26. 21 – 23 & 73 – 76 View FIGURES 73 – 80. 73 – 76 ).
