Holotype : ♂ , COLOMBIA : Cundinamarca , Choachi (waterfall La Chorrera ), 4°35′33″N , 73°57′36″W , elevation 2500 m , 1–2.ii.2017 , leg. Wolfram Mey , genitalia slide no. AD1119 ( MfN / UNC ) . Paratype : 1 ♂ , same label data as holotype, genitalia slide no. AD1120 ( MfN ) . Diagnosis. Externally, this new species can be confused with some other dark-coloured species. In the male genitalia, the unique shape of the five-clawed carinae ( Fig. 24 ), slender lateral processes of the phallus ( Fig. 24 ), spinose uncus ( Figs 15, 16 , 23 ), and unique dorsal process of the valva with a basal arc ( Figs 18, 19 ) distinguish D. ursipedella sp. nov . from all known congeneric species. Male ( Figs 13, 14 ). Forewing length 3.7–4.0 mm; wingspan 8.0–8.7 mm (n = 2). Head: frons and palpi pale grey; pecten small, slender, grey; frontal tuft and collar comprised of lamellar scales; frontal tuft brown-grey, distally pale grey, basally blackish grey; collar grey, distinctive; antenna longer than one half the length of forewing; flagellum brown-grey; sensillae 4–5 times longer that the width of the flagellum. Tegula and thorax covered with brown-grey scales. Forewing brown-grey, sparsely speckled with some dark brown scales; fringe grey, with an indistinctive fringe line; forewing underside dark brown, without spots or androconia, except for blackish grey special scales along costal margin at the forewing base. Hindwing dark brown-grey on upper side and underside, without androconia; fringe grey. Legs blackish grey on upper side, pale grey to grey cream on underside. Abdomen brown-grey on upper side, pale grey, glossy on underside; genital plates contrasting with the colour of the abdomen, cream; anal tufts lateral, almost merging, comprised of long brown scales. Male genitalia ( Figs 15–30 ) with capsule 480–490 µm long, 240–280 µm wide. Uncus ( Figs 15, 16 , 25 ) comprised of two relatively long and slender lateral lobes and short, rounded median lobes; the latter covered with thickened spines distally. Socii ( Figs 23 , 25 ) large, weakly paired or non-paired, with very little spines mostly on the medial fold ( Fig. 25 ). Valva ( Figs 18, 19 , 21 , 26–28 ) ca. 315 µm long (excluding the basal process); ventral lobe with a basal fold ( Fig. 27 ); dorsal process ( Figs 18, 19 , 22 , 26, 28 ) greatly developed but at a distance from the ventral lobe and with a basal arc ( Figs 19 , 26 ); there is also a short but wide lobe-like process in between the dorsal and ventral lobes ( Figs 22 , 28 ). Anellus absent. Vinculum relatively large, rounded or triangular distally ( Figs 19 , 21 , 29, 30 ). Phallus ( Fig. 24 ) 280–305 µm long, wide basally and apically, constricted medially, with slender lateral processes and well-developed five-clawed carinae. Female . Unknown. Bionomics ( Figs 11, 12 ). The host plant is unknown (see Discussion). Adults fly in February. Otherwise, the biology is unknown. Distribution . This species is known from a single locality in Colombia (Choachi, Cundinamarca , near La Chorrera waterfall), at an altitude of about 2500 m . FIGURES 13–20.

The species name is derived from Latin ursus (a bear) and pedis (a foot) in reference to the distinctive claw-like carinae of the phallus in the male genitalia.
