Type material. Holosoma rambouseki Jedlička. Consists of 3♂♂, 1♀ specimens, all preserved in NMPC. No specimen from the type series was explicitly designated as type or holotype in Jedlička’s work, thus all the samples are treated as syntypes (cf.Article 73.2., ICZN 1999). Of these specimens, a male is chosen for lectotype designation. It is labelled as follows: ‘CHUNG–KING Szetschuan [‘e’ almost illegible] Coll. Dr. Becker [w, p] // Rambouseki mihi det. Ing. Jedlička [w, h/p] // TYPE [r, with black frame, p] // Paratypus [r, p]’. The remaining three specimens are treated as paralectotypes: 1♂, ‘CHUNG–KING Szetschuan [‘e’ almost illegible] Coll. Dr. Becker [w, p] // TYPE [r, with black frame, p] // Holosoma Rambouseki mihi DET.ING.JEDLIČKA [p, h/p]’; 1♂, ‘CHUNG–KING Szetschuan [‘e’ almost illegible] Coll. Dr. Becker [w, p] // TYPE [r, with black frame, p] // Rambouseki mihi det. Ing. Jedlička [w, h/p]’; 1♀, ‘CHUNG–KING Szetschuan [‘e’ almost illegible] Coll. Dr. Becker [w, p] // TYPE [r, with black frame, p] // Rambouseki mihi det. Ing. Jedlička [w, h/p]’.

Diagnosis. This species differs from other taxa of the “ rambouseki ” group except P. emeishanicus in its PW/HW <2.10 ( Table 2). It is readily distinguished from P. emeishanicus by its PW/PL ≤1.61. In addition, P. rambouseki differs from all members of the group in the male mesotibia strongly curved and dilated distally, highest W/Lp2, and apical lamella of median lobe bent to left ( Fig. 12D ).

Description. Habitus. Moderately large specimens (BL: about 12.4–13.3 mm, BW: 4.7–5.2 mm), with ovate, subconvex body ( Figs 12A, B, E ). Ratios and measurements. See Table 2. Color and luster. Body dark brown to black; antennae, palpi, tibiae and tarsi rufopiceous. Integument moderately shiny, without iridescence. Punctuation. Dorsal surface without punctuation; prosternum punctate at sides; proepisternum finely and shallowly punctate and striate; meso- and metepisternum, and metasternum at sides with dense and moderately strong punctuation; abdominal ventrites 1–5 punctate and finely rugose at sides, ventrite 6 densely punctate at apex. Head. About half as wide as pronotum ( Table 2). Mentum tooth with apex more or less emarginate, with paramedial border finer than in other taxa of “ rambouseki ” group ( Fig. 12F ). Thorax. Pronotum with sides rounded toward posterior angles (PW/PB: 1.07–1.11); maximum width in posterior third; laterobasal impressions long, shallow, nearly reaching basal margin; base indistinctly sinuate; anterior angles rounded, rather projected. Prosternum with median longitudinal sulcus distinct; prosternal process elliptic, widely rounded apically ( Fig. 12G ). Metepisternum about one-and-a-half times wider than long ( Table 2), with lateral margin straight, its coadunation with epipleuron short, located anteriorly ( Fig. 12H ). Elytra. Apical sinuation weak, poorly defined. Basal margin distinct laterally, forming distinct denticle at shoulder, disappearing medially at level between striae 2 and 3. Parascutellar striola rather reduced, punctiform; striae impunctate. Intervals 1–7 subconvex, interval 8 more convex and more raised than other intervals. Legs. Metacoxal basal sulcus barely reaching lateral third.Male mesotibia slightly concave on lateral margin,and significantly thickened apically along medial margin ( Fig. 12B ). Protarsomeres 1–3 of male strongly dilated, with second segment one and a half time wider than long (W/Lp2: 1.51–1.55). Male genitalia. Median lobe ( Figs 12C, D ) with basal bulb moderately long; angle between basal bulb and shaft acute; shaft long, swollen; apex short, curved ventrally; apical lamella more elongate than in other representatives of “ rambouseki ” group, left-orientated, rounded at tip. Female genitalia. Basal gonocoxite with three lateroapical setae. Apical gonocoxite as in P. leigongshanicus ( Fig. 12I ). Bursa copulatrix with small dorsal sclerite (not visible in Fig. 12J ); spermatheca very long, slightly differentiated, with seminal canal narrow and receptaculum twisted apically; spermathecal gland connected in apical third of seminal canal ( Fig. 12J ).

Distribution. This species is restricted to Mount Jinfo, Nanchuan District, Chongqing Municipality, China. Most probably, it may inhabit other parts of Dalou Mts., which extend also to Guizhou Province.

Bionomics. Almost nothing is known about the bionomics of this species. Label data indicate only that a single specimen was found under a stone, in a broadleaf forest, in the daytime.

Notes. In original description, Jedlička (1931: 21) compared the species with O. helopioides . Nevertheless, he placed it in another genus, Holosoma Semenov, 1889 , which at that time was classified in tribe Oodini (see Guéorguiev 2014).
