8. Pseudoodes leigongshanicus sp. n.

( Figs 11 A–J, Table 2)

Type material. Holotype ♂, ‘ CHINA, W GUIZHOU prov. LEIGONGSHAN, Xijiang 29 May–2 Jun 1997 1200– 1900 m, Bolm lgt. [w, p]’ (NHMB). Paratype ♀, with first label identical to that of holotype (NHMB).

TME: 2 specimens. TGE: 1♂, 1♀.

Diagnosis. This species is most similar to P. hunanensis but differing in characters noted in “Diagnosis” for this latter species. It differs from other members of the species group treated except P. rambouseki in its slightly smaller and narrower body ( Table 2). P. leigongshanicus is rеadily separated from P. rambouseki in its greater PW/HW and PW/PL, less widened male protarsomere 2 ( Table 2), male mesotibia almost straight, and apical lamella of median lobe wider and straight ( Figs 11F ).

Description. Habitus. Moderately large specimens (BL: 12.5–12.9 mm, BW: 5.0– 5.1 mm), with ovate, subconvex body ( Figs 11A, H ). Ratios and measurements. See Table 2. Color and luster. Body dark brown to black; antennae, palpi, and legs piceous to rufous (legs less distinctly bicolorous than in P. hunanensis ). Integument moderately shiny, without iridescence. Punctuation. Dorsal surface without punctuation except posterolateral parts of pronotum with large but shallow punctures extending laterally to posterior half; prosternum at sides and proepisternum finely and shallowly punctate; meso- and metepisternum, and metasternum at sides with denser and stronger punctuation; abdominal ventrites 1–5 punctate and rugose at sides and submedially, ventrite 6 punctate at apex. Head. Less than half as wide as pronotum ( Table 2). Mentum tooth truncate at apex, with paramedial border distinct ( Fig. 11B ). Thorax. Pronotum with sides slightly rounded toward posterior angles (PW/PB: 1.07); maximum width in posterior third; laterobasal impressions long, shallow, nearly reaching basal margin; base feebly sinuate; anterior angles rounded, moderately projected. Prosternum with median longitudinal sulcus shallow; prosternal process elliptic, widely rounded apically ( Fig. 11C ). Metepisternum about one-and-a-half times wider than long ( Table 2), with lateral margin straight to convex, coadunation with epipleuron short, located anteriorly and in middle ( Fig. 11D ). Elytra. Apical sinuation indistinct, poorly defined. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level between striae 2 and 3. Parascutellar striola shallow, punctiform, less impressed than other striae; striae impunctate except 1–4 in anterior sixth. Intervals 1–7 subconvex, interval 8 more convex than other intervals. Legs. Metacoxal basal sulcus reaching lateral third. Male mesotibia slightly dilated distally. Protarsomeres 1–3 of male strongly dilated, with second tarsomere more than one-third wider than long (W/Lp2: 1.44). Male genitalia. Median lobe ( Figs 11E, F, G ) in lateral view very similar to that of P. hunanensis , but angle between shaft and basal bulb less acute; apical lamella short, less acute than in P. hunanensis . Female genitalia. Basal gonocoxite with four lateroapical setae.Apical gonocoxite as in P. hunanensis , only dorsomedial ensiform seta located equidistant from middle and base ( Fig. 11I ). Spermathecal complex as in P. hunanensis ( Fig. 11J ).

Etymology. The species is named for Leigongshan Mountain where the type locality is situated.

Bionomics. Nothing is known about the bionomics of this species. Label data show only that it was found at high altitude, most probably in a forest environment.

Distribution. The species is known only from Leigongshan Mountain situated in Qiandongnan Miao and Dong Autonomous Prefecture, Guizhou Province, China. Leigonshan Mountain is the highest massif in the southeastern part of Guizhou.
