Head coloured like wing background, covered with white or whitegrey erect scales, appressed only on frons. Antenna long, filamentous. Labial palp composed of three segments, middle segment markedly larger, with characteristic erect scales. Maxillary palp reduced, hardly visible. Forewing elongate, with a slightly pointed apex, varying in pattern; two colour forms can be distinguished: dominated by white or white-grey scales. In forewing , subcostal vein (Sc) reaching costal margin at 1/2 of wing length; radial veins free, R1–R4 reaching costal margin, R5 reaching termen margin near wing apex; medial and cubital veins free, Cu1 and Cu2 reaching dorsal margin close to one another; Pcu conspicuous at base and near dorsal margin, hardly visible in central part; anal veins A1–A2 free only near wing base, remaining parts fused, conspicuous; pterostigma conspicuous, limited by veins Sc and R2. Light-coloured form . Scape and pedicel white, flagellomeres white, with narrow brown bands. Labial palp: first segment white, second segment dominated by grey-brown scales, with white scales only near first segment, third segment bicoloured: white and grey-brown. Forewing background white, with scattered grey-brown scales in middle part; small rectangular grey-brown spots scattered all over wing; costal margin white, with small rectangular brown spots, two largest spots located near 1/2 and at 2/3 of wing length (from base); along dorsal margin, a conspicuous white streak interspersed with small rectangular brown spots, two largest spots connected by oblique bands with spots near costal margin; whitish area in apical part; along termen margin, three conspicuous black rectangular spots; cilia light-grey, with a narrow white band. Dark-coloured form . Scape and pedicel grey, only several initial flagellomeres with wide white bands, remaining flagellomeres uniformly dark-grey. Labial palp: first segment white-grey, second segment grey-brown, third segment bicoloured: grey and grey-brown. Forewing background grey-white, with scattered brown spots of various size: from very small to slightly larger; basal area white, with a very small proportion of brown scales; near costal margin, several small, light brown spots, largest spot located near wing apex; near dorsal margin of wing, close to basal whitish area, a larger rectangular dark brown spot, separated from next one by a whitish area; apical part of wing with a markedly larger proportion of white scales; at wing apex, a conspicuous black spot; along apical part of wing, near cilia, conspicuous small black dots; cilia coloured like wing background. Hindwing light grey, cilia long, coloured like wing background; stalk of veins Sc+R1 reaching costal margin at 4/5 of wing length; remaining radial veins R2–R5 fused, reaching costal margin near wing apex; medial veins M1–M3 and cubital veins Cu1–Cu2 free; postcubital vein CuP poorly visible only near wing base, remaining part conspicuous; anal veins A1–A2 free, conspicuous. Abdomen cylindrical, coloured like wing background. In male gentalia , anal tube long, membranous. Uncus reduced. Tegumen poorly defined, usually its middle part very narrow. Socii wide, covered with hairs. Gnathos poorly visible, usually fused with socii. Saccus very long and narrow. Valva with a gently rounded apex, constricted at 1/3 of its length; each valva, near vinculum with apodeme, apical part of apodeme clearly dentate. Aedeagus long and thin, strongly sclerotized, in central part convex; apical part wider, membranous, with a single long, conspicuous, dentate, pointed spine; basal part of aedeagus wider, sclerotized on one side; ductus ejaculatorius small, membranous; aedeagus 1/3 longer than valva. In female genitalia , posterior and anterior apophyses long and thin; anterior apophyses hooked at apex. Ductus bursae strongly sclerotized, markedly dilated near inception of corpus bursae, more sclerotized, twisted due to sclerotization in this part; only short section before inception of corpus bursae membranous, with small membranous ductus bullae. Ductus bullae short, evenly thin, bulla seminalis large, elongated, membranous, ductus seminalis narrow, membranous. Corpus bursae nearly spherical, concave in central part, poorly sclerotized, signum absent. In side view, corpus bursae looks like two fused spheres, one of them slightly larger. Biology : Species of Arabis and Draba have been recorded as larval foodplants in several countries, and Descurainia sophia in the British Isles (Ford 1941). Distributional area : mountains of Central Europe, Fennoscandia, Russia, Altai (Fig. 13). Notes . The two species are very similarly coloured, with a similar pattern on forewings. Both of them have vary significantly in forewing pattern, from uniformly grey with a very simplified pattern to the typical colour forms of both species. When identifying very worn specimens, species determination is possible only on the basis of the male or female genitalia. : Published as part of Baraniak, Edward, 2016, Rhigognostis senilella (Zetterstedt, 1839) and R. marmorosella (Wocke, 1849): two valid species distinguishable in genitalia (Lepidoptera, Plutellidae) in Zootaxa 4084 (3) , DOI: 10.11646/zootaxa.4084.3.2, http://zenodo.org/record/1052143 : {"references": ["Wocke, M.
