Xiao-Dong Yang ( CCCC ) ; 1 male , Yunnan , Longchuan , Husa Xiang , 1,700 m , 2017.VI.24 , leg. Yung-Jen Chang ( CCCC ) . Complementary description. Male. Body length 40.5–61.3 mm , humeral width 12.3–19.3 mm . Legs with tarsi four-segmented, but tarsomeres IV and V in some individuals incompletely fused ( Fig. 12 ). Male endophallus ( Fig. 10 ) stout, about 2.4 times as long as the median lobe, weakly curved near apical two-fifths dorsally; APH well defined, BPH and MPH vaguely defined due to the highly reduced cs; MPH subdivided into MT, CT and PB by constriction, CT and PB moderately swollen at middle; PB with pronounced si and indistinct sf; relative lengths of APH: MPH: BPH: PB: CT: MT = 1.0: 2.9: 0.5: 0.6: 1.0: 1.3. APH, divided into ab and bb; im moderately developed; ab gradually broadened distally; bb provided with a pair of rod-like sclerites associated with the paired ejaculatory ducts, in dorsal view ( Fig. 10a ) protuberant behind the widely separated gn and deeply emarginated apically. Spicules mainly distributed on CT, apical part of PB and whole surface of ab. Female. Body length 57.4–66.7 mm , humeral width 19.6–22.3mm . Distribution. China (new Country record): Xizang , Yunnan ; Laos , India , Myanmar , Bhutan . Remarks. This species and Pseudomeges varioti Le Moult, 1946 show allopatric distribution in Yunnan . The former is distributed in the westernmost region (Longchuan County), while the latter was reported from the southern end (Jinghong City: Weigel, Meng & Lin 2013 ). Pseudomeges marmoratus can be distinguished from the latter by its head smaller, not protruding at sides in front view, lower eye lobe larger, nearly as long as gena, instead of only 0.6 times, antennal scape thicker, antennomere III straight, antennomeres III to V not annulated with light pubescence at base, elytra longer compare to its head and pronotum united, scutellum slender, not transverse.
