Diagnosis. Belongs to C. rybyensis species group. It differs from all Palaearctic species of the group (except C. hortivaga ) by transverse S2 basal platform ( Fig. 3 View FIGURES 1–5 ) and characteristic coloring of the hind leg—coxa with apical yellow spot, trochanter yellow, femur black, tibia predominantly black with inner yellow stripe, tarsi darkened. It differs from the morphologically similar C. amamiensis Tsuneki, 1961 which is only found on the Ryukyu Islands ( Japan), by the dark color of hind legs (predominantly yellow in C. amamiensis ), black or with yellow spot metanotum (orange-yellow in C. amamiensis ), yellow narrow band of T2 (large and orange-yellow in C. amamiensis ) and dense punctation (the punctures interspaces on T2 and T3 are smaller than in C. storozhenkoi , but larger than in C. amamiensis ).

Comparison of features with most related species C. hortivaga given in Table 1.

Description. Female and male. Head slightly transverse, midfrontal carina abruptly sloping at dorsal end, ending far from midocellus. Punctation of clypeal median part large and dense, without micropunctures and microsetation. Silver setation on clypeal lateral parts relatively weak and not concealing integument. Mesosoma . Pronotum with anterolateral carina lacking dorsally. Punctation dense and large, on mesonotum central part with distinct interspaces. Tegula with single (1–3) punctures. Metapostnotum with deep median furrow, predominantly smooth or oblique microrugose, laterally with conspicuous oblique ridges, basally with transverse delicate folds. Legs. Typical for related species. Wings. Jugal lobe of hindwing near 1/5 of anal cell. Metasoma. T1 without small, apicomedian fossa. S2 basal platform transverse, near 1/4 of segment length ( Fig. 3 View FIGURES 1–5 ). Coloration ( Fig. 2 View FIGURES 1–5 ). Black, with yellow pattern. Clypeus (except free margin), lateral part of face, supraclypeal sclerite (at male often only medially), large spot on tegula yellow. Fore and mid legs with yellow coloration on: femora inner surface in apical part, tibiae base and inner surface, tarsi. Midcoxa yellow apically. Hind leg coxa with apical yellow spot, trochanter yellow, femur black, tibia predominantly black with inner yellow stripe, tarsi darkened. T2 with large, apical band slightly narrowed medially, usually reduced apical band on T2–T5 (at females) or T2–T6 (at males), S2 with yellow apical band or lateral spots. Sometimes (predominantly in specimens from mainland) yellow lateral spots on pronotum and (or) transverse spot on metanotum present too, and apical band on T5 (at females) or T6 (at males) large and not reduced.

Female ( Figs 1–5 View FIGURES 1–5 , 9–11 View FIGURES 9–14 , 21, 23 View FIGURES 21–30 ). Body length 10.9–14.2 mm ( holotype 12.0 mm). Head ( Figs 4, 5 View FIGURES 1–5 ) ratio H:W = 0.84, POL:OOL = 0.63. Clypeal median part dorsally trapeziform, ratio H:W = 0.92 ( Fig. 9 View FIGURES 9–14 ), concave apically, concavity near 1/2 of its length from fore margin. Median part of clypeal free margin slightly doubly notched, with conspicuous lateral angles. Mandibula with two wide teeth in inner edge ( Figs 4, 5 View FIGURES 1–5 ). Metasoma. T1 ratio L:W = 0.93 ( Fig. 10 View FIGURES 9–14 ), apical semitransparent border high ( Fig. 11 View FIGURES 9–14 ). Pygidial plate L:W = 2.10, slightly shiny, sculpture rugose (brainlike) and prominent ( Fig. 21 View FIGURES 21–30 ).

Male ( Figs 6–8 View FIGURES 6–8 , 15–17 View FIGURES 15–20 , 25, 27, 29 View FIGURES 21–30 ). Body length 7.2–10.4 mm. Head ( Figs 7, 8 View FIGURES 6–8 ) ratio H:W = 0.88, POL:OOL = 0.64. Clypeal median part dorsally trapeziform, ratio H:W = 1.1 ( Fig. 15 View FIGURES 15–20 ), distinctly convex. Row of agglutined setae on clypeal free margin near 0.64× distance that separates it from opposite row. Median part of clypeal free margin almost straight. Flagellomeres without fringe of setae, F11 not curved. Mandibula edentate in inner edge ( Fig. 7 View FIGURES 6–8 ). Metasoma. T1 ratio L:W = 1.00 ( Fig. 16 View FIGURES 15–20 ), apical semitransparent border high ( Fig. 17 View FIGURES 15–20 ). S8 apex not deep notched ( Fig. 25 View FIGURES 21–30 ). Genitalia— Figs 27, 29 View FIGURES 21–30 .

Etymology. The specific epithet is a patronym honoring S. Yu. Storozhenko (Vladivostok, Russia) on the occasion of his 70th birthday and in recognition of his many contributions to the study of Orthoptera and other Insects.

Distribution. Russia (Amurskaya Province, Khabarovsk Territory, Primorsky Territory, Kuril Islands: Kunashir), China ( Heilongjiang, Jilin, Hebei, Shandong, Hubei), Korean Peninsula, Japan ( Hokkaido, Honshu, Kyushu, Shikoku, Ryukyu). Record from Yunnan ( Dollfuss 2021b: 599) is doubtful (possibly refers to C. fortinata Cameron, 1902 ) on geographical reason.
