( Figs. 2 , 7 , 9 ) Magninia tonkinea Clermont, 1932: 215 , fig. on page 215. Type locality: Tien-Yen, Tonkin , Vietnam . Type material examined. Holotype , female, “ Tonkin / Tien-yen ”, “ex. Jeanvoine / Coll. Clermont ”, “ Type ”, “ Magninia / tonkinea / Clerm. / type ”, “ tonkinea Clerm ”, “TYPE”, “ Museum Paris / Coll. M. Pic ” ( MNHN ). Examined by photographs taken by Gan-Yan Yang & Hong-Liang Shi in 2011. Other material examined. China ( Guangxi ) : 1 male , Guangxi , Jinxiu , Dayaoshan , 900 m , 2018.VIII.11 , local collector ( CCCC ) . China ( Hainan ) : 1 male , Hainan , Ledong , Jianfengling , 950 m , 2015.V.7-12 , leg. Yu-Tang Wang & Nan-Yi Tsai ( CCCC ) ; 1 female , ditto except 2018.V.21 , local collector ( CCCC ) ; 1 female , ditto except 2018.VI.2 , local collector ( CCCC ) . Complementary description. Male ( Fig. 2 ). Body length 48.5–49.4 mm , humeral width 14.6–15.0 mm. General appearance similar to the female described by Clermont (1932) . Body slightly slenderer. Antenna about 2.0 times of body length. Legs relatively longer and thicker. Endophallus in everted condition ( Fig. 9 ), almost identical to Meges gravidus as described above, but relatively slenderer. Female. Body length 55.0– 57.3 mm , humeral width 16.6–17.8 mm . Distribution. China : Hainan (new Province record), Guangxi ; Vietnam : “ Tonkin ”. FIGURES 6–7.

Endophallus of Meges spp. and Pseudomeges spp. 8 , Meges gravidus ( Pascoe, 1858 ) ; 9, M. tonkineus ( Clermont, 1932 ) ; 10, Pseudomeges marmoratus ( Westwood, 1848 ) ; 11, P. aureus Bi, Chen & Lin sp. nov. a, apical phallomere in dorsal view; b, apical phallomere in non-everted condition. Remarks. The resemblances of the endophallic structures between this species and Meges gravidus ( Figs. 8. 9 .), indicate a close relationship. This species can be easily distinguished from the latter by its larger body size, antennae longer, protibial subapical tooth sharper, elytra broader with smooth base which lacks remarkable granule, elytral humeri remarkably spined and elytral disk bearing fewer maculae of relatively lighter color. Huang et al . (2002) firstly recorded this species from Guangxi , China . We confirmed the distribution in Guangxi and added Hainan as a new locality based on new material.
