description: 7. Pseudoodes hunanensis sp. n.
(Figs 10 A–I, Table 2)
Type material. Holotype ♂, ‘ China, Hunan, Tianpingshan, Xiaozhuangping, 1400m 29.78637, 110.09285 [w, p] // 2015.6.14 N, along road LIANG Hongbin collector Institute of Zool., CAS [w, p]’ (IZAS). Paratypes: 2♂♂, 3♀♀, all with first and second labels as in the holotype (IZAS, NMNHS).
TME: 6 specimens. TGE: 1♂, 1♀.
Diagnosis. This species is separated from all other members of the “ rambouseki ” group by its much wider metepisternum (see Table 2) and bicolored legs. It is most similar to P. leigongshanicus but differs in its slightly larger size, mentum tooth narrower apically, laterobasal impressions of pronotum longer nearly reaching basal margin, prosternal process shortly rounded at apex, male protarsomere 2 less widened (W/Lp2: 1.32–1.35), and median lobe more pointed at apex (Fig. 10G).
Description. Habitus. Rather large specimens (BL: 13.0– 14.4 mm, BW: 5.1–5.7 mm), with ovate, subconvex body (Figs 10A, B). Ratios and measurements. See Table 2. Color and luster. Body dark brown to black; antennae, palpi, tibiae and tarsi rufous, coxae, trochanters and femora darker than tibiae and tarsi. Integument moderately shiny, without iridescence. Punctuation. Dorsal surface without punctuation; prosternum and metasternum at sides, and meso- and metepisternum with dense and moderately strong punctuation; proepisternum finely and shallowly punctate; abdominal ventrites punctate at sides. Head. Less than twice as wide as pronotum (Table 2). Mentum tooth with apex shortly truncate, with paramedial border distinct (Fig. 10C). Thorax. Pronotum with sides slightly rounded toward posterior angles (PW/PB: 1.05–1.08); maximum width in posterior fourth; laterobasal impressions long, shallow, nearly reaching basal margin; base indistinctly sinuate; anterior angles rounded, moderately projected. Prosternum with median longitudinal sulcus distinct, deeper and located more posteriad than in P. leigongshanicus; prosternal process elliptic, shortly rounded apically (Fig. 10D). Metepisternum more than one-and-a-half times wider than long (Table 2), with lateral margin straight to convex, coadunation with epipleuron short, located at middle (Fig. 10E). Elytra. Apical sinuation weak, poorly defined. Basal margin distinct laterally, forming wellexpressed distinct denticle at shoulder, disappearing medially at level between striae 2 and 3. Parascutellar striola punctiform, shallow, less impressed than other striae; striae 1–3 superficially punctate anteriorly, remaining striae impunctate. Intervals 1–7 subconvex, interval 8 more convex and more elevated than other intervals. Legs. Metacoxal basal sulcus reaching lateral third. Male mesotibia slightly dilated distally. Protarsomeres 1–3 of male strongly dilated, with second segment one-third wider than long (W/Lp2: 1.32–1.35). Male genitalia. Median lobe (Figs 10F, G) with basal bulb narrow, moderately long; angle between basal bulb and shaft acute; shaft long, swollen medially; apex short, curved ventrally; apical lamella short, pointed. Female genitalia. Basal gonocoxite with four lateroapical setae. Apical gonocoxite short, subtriangular, with two minute, barely observable dorsolateral ensiform setae, dorsomedial ensiform seta near middle, and nematiform setae equidistant from middle and apex (Fig. 10H). Bursa copulatrix without dorsal sclerite; spermatheca very long, undifferentiated, with seminal canal coiled apically; spermathecal gland connected near middle, but at proximal half of seminal canal (Fig. 10I).
Etymology. The species is named for Hunan Province, where the type locality is situated.
Distribution. Known only from Mount Tianping Shan situated in the eastern part of Wuling Mountain Range, Sangzhi County, northwestern Hunan Province, China. Given the fact that the type locality is very close to the Hunan / Hubei border, it is highly probable that this species occurs in adjacent Enshi Tujia and Miao Autonomous Prefecture, Hubei Province as well.
Bionomics. This species was collected along a muddy road at a rainy night. In that wet and cold night, beetles stayed near small puddles on the road, or rested in wet places near the bed of a ditch where water was flowing.
Notes. Additional data about the type locality of the new species are as follows. GPS coordinates: 29.78637, 110.57105; altitude: 1,410 m a.s.l.
