Pseudoodes tianlinensis sp. n. ( Figs 13 A–G, Table 2 ) Type material . Holotype ♂ , 2002–V–31 [ Guangxi , Tianlin, Cenwanglao Shan Mountain] 1500–2062 m [Yang Xiujuan leg.] [w, p] // China , Guangxi , Tianlin Cengwanglao Shan, 1500–2062m , YANG Xiujuan collector Museum of Hebei University [w, p] (HBUM). TME: 1 specimen . TGE: 1♂ . Diagnosis . This species differs from other wingless members of the species group except P . rambouseki in its smallest MA/MM ( Table 2 ). It is most similar to P . emeishanicus , from which it can be separated by its longer pronotum (see PW/PL, Table 2 ) and characters noted in the “Diagnosis” under P . emeishanicus . Pseudoodes tianlinensis differs from P . rambouseki in its pronotum much wider than the head (PW/HW>2.10), different apical lamella of median lobe ( Fig. 13G ), slightly dilated and almost straight male mesotibia, and W/Lp2: 1.26. Description . Habitus . Specimens of moderately large size (BL: 13.5 mm , BW: 5.3 mm ), with ovate, subconvex body ( Fig. 13A ). Ratios and measurements . See Table 2 . Color and luster . Body dorsal surface black, underside dark brown, appendages piceous to rufous. Integument moderately shiny, without iridescence. Punctuation . Dorsal surface without punctuation; prosternum and metasternum at sides, and metepisternum moderately punctate; proepisternum nearly smooth; mesoepisternum shallowly punctate; abdominal ventrites 1–5 punctate and finely rugose at sides, ventrite 6 punctate at apex. Head . Less than half width of pronotum ( Table 2 ). Mentum tooth with apex truncate, with paramedial border distinct ( Fig. 13C ). Thorax . Pronotum ( Fig. 13B ) with sides slightly rounded toward posterior angles (PW/PB: 1.06); maximum width in posterior third; laterobasal impressions shallow but distinct; base nearly straight; anterior angles rounded, appreciably projected anteriorly. Prosternum with median longitudinal sulcus shallow, located more medially than in P . emeishanicus ; prosternal process elliptic, more narrowly rounded apically than in other species of “ rambouseki ” group except P . emeishanicus ( Fig. 13D ). Metepisternum significantly wider than long (MA/MM: 1.50), with lateral margin slightly convex, coadunation with epipleuron relatively long, located anteriorly and in middle ( Fig. 13E ). Elytra . Apical sinuation moderate, well-defined. Basal margin distinct laterally, forming a small denticle at shoulder, disappearing medially at level between striae 2 and 3. Parascutellar striola rather reduced, punctiform, appreciably less impressed than other striae; striae superficially punctate anteriorly. Intervals 1–7 subconvex, interval 8 appreciably more convex than others. Legs . Metacoxal basal sulcus reduced at side, barely reaching lateral third. Male mesotibia slightly but more dilated distally than in P . emeishanicus . Protarsomeres 1–3 of male moderately dilated, with second tarsomere wider than long (W/Lp2: 1.26). Male genitalia . Median lobe ( Figs 13F, G ) with basal bulb moderately long, narrow; angle between basal bulb and shaft acute; shaft long, swollen proximally; apex short, curved ventrally; apical lamella short, rounded. Female genitalia . Unknown. Etymology . The species is named for Tianlin County, where the type locality is situated. Distribution . Presently known only from Cenwang Laoshan Mts. in northwestern Guangxi Zhuang Autonomous Region, China . Bionomics . Nothing is known about the bionomics of this species.
