JAPAN : N i i g a t a Prefecture : 2♂♂ , 1♀ , ‘ Niigata Pref. , Jyôetsu-shi, Ookata-ku, Katamachi 3.IX.1976 , Seiji Morita leg.’ ( NMNHS ); 1♂ , same data, but collected 25.V.1991 ( NMNHS ); 1♀ , same data, but collected 2.VI.1991 ( NMNHS ). Other material examined . CHINA : I m p re c i s e localities : 8♂♂ , 8♀♀ , China ( IZAS , NMNHS ). J i a n g x i Province : 1♀ , Jiangxi , Liantang, field margin, 1953.8. ( IZAS ). TME: 22 specimens . TGE: 3♂♂ , 1♀ . Diagnosis . Members of this species are readily distinguished from those of other Palaearctic Oodes by their larger size, more than 12.5 mm , and very low PA/PW ( Table 4 ). Description . Habitus . Specimens of large size (BL: 12.8–15.0 mm, BW: 5.3–6.2 mm ), with subovate, moderately convex body ( Figs 16A, B, D, F ). Ratios and measurements . See Table 4 . Color and luster . Body including palpi and legs black; antennae piceous to rufopiceous. Integument dorsally and ventrally moderately shiny, without iridescence. Punctuation . Dorsal surface without punctuation; sides of prosternum and metasternum, meso- and metepisternum densely punctate; proepisternum finely rugose; abdominal ventrites finely rugose and punctured. Head . Half or less than half as wide as pronotum (PW/HW: 2.00–2.16). Mentum tooth with distinct paramedial border ( Fig. 16C ). Thorax . Pronotum with sides rounded toward posterior angles (PW/PB: 1.02–1.06); maximum width in posterior third; laterobasal impressions indistinct; base moderately sinuate; anterior angles rounded, moderately projected anteriorly. Prosternum with median longitudinal sulcus shallow; prosternal process with apex rounded and border nearly complete, reduced at apex ( Fig. 16E ). Metepisternum longer than wide (MA/MM: 0.87–1.00), with lateral margin convex and coadunation with epipleuron rather long, located anteriorly ( Fig. 16G ). Elytra . Apical sinuation weak, but distinct. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level between striae 2 and 3. Granulation in marginal furrow continuous. Parascutellar striola and stria 1 shallower than other striae, striola punctate as well as striae 1–4 anteriorly; stria 7 as distinct as stria 6. Intervals 1–7 rather flat, interval 8 convex. Legs . Metacoxal basal sulcus extending to lateral fourth. Male mesotibia not modified. Protarsomeres 1–3 of male moderately dilated, with second segment longer than wide (W/Lp2: 0.82–0.88). Male genitalia . Median lobe ( Figs 17A, B, C, D ) with basal bulb short and narrow; angle between basal bulb and shaft nearly straight; shaft long and swollen; apex short, tapered and curved ventrally; apical lamella widely rounded; ostium long, but shorter than in O . helopioides , not reaching basal bulb. Female genitalia . Basal gonocoxite with ten or so lateroapical setae. Apical gonocoxite without dorsolateral ensiform setae, with nematiform setae ( Fig. 17E ). Spermatheca coiled apically ( Fig. 17F ). Habitat . See “Habitat” under Pseudoodes vicarius . Distribution . Palaearctic Region: Japan (Honshu), China ( Jiangsu , Jiangxi ). Notes . Describing the male protarsomeres, Habu & Baba (1960) stated that “ segment 3 is almost as long as segment 2, slightly narrower than this, with apex oblique ” (ibid.: 32) and “ with lateral sides parallel ” (ibid.: 33). We measured the lengths of male protarsomeres 2 and 3 in four Chinese specimens and two topotypical specimens. It was established that protarsomere 3 is about 1.15–1.25 times longer than protarsomere 2, and thus, the above indication by Habu & Baba is not correct. It should be noted also that specimens from China have smaller body size ( 12.8–14.9 mm , original data), while those from Japan have body length 14.0– 15.2 mm (data from Habu & Baba 1960 and original data).
