Popis: 9. Pseudoodes rambouseki (Jedlička, 1931), comb. n. (Figs 12 A���J, Table 2) Holosoma rambouseki Jedlička, 1931: 21 (type locality: ��� China mer.: Prov. Szetschuan: Chung-king���). References. Holosoma rambouseki: Csiki 1933: 1675; Wu 1937: 148 (���Szechnan���); Lorenz 1998: 304; Bousquet 2003: 444; Lorenz 2005: 324; Bousquet 2017: 497. 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.

IOZ CAS (IZAS); 1♂, ���China���Chongqing Jinfo Shan 7.5.��� 13.5.2018 Lgt. E. Kučera��� (cEK). TME: 9 specimens. TGE: 2♂♂, 1♀. Diagnosis. This species differs from other taxa of the ��� rambouseki ��� group except P. emeishanicus in its PW /HW 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 Gu��orguiev 2014). 10. 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. TABLE 2. (Continued) 10.
