Diagnosis.

Labial palps in males approx. 20% longer than in U. austriacalis and U. cretacea ; outer side of labial palps’ 2nd and 3rd palpomeres barely darker than rest of labial palps. Maculation of forewing usually more pronounced than in U. austriacalis , the apical brown streak often broader; hindwing in both sexes with greyish cream-white inner area contrasted by a prominent dark brown postmedial line and dark brown terminal band, especially in specimens where the postmedial line and the outer band are fused into a broad band; in contrast, the hindwings’ upper side is evenly dark brown in females of U. austriacalis . In the male genitalia, the fibula of U. donzelalis is generally broader and elongate triangular, tapering from the broad base towards the apex; in U. austriacalis the fibula is narrower and evenly broad from the base to the subapex. In the female genitalia, the signum of U. donzelalis is 4.1-5.1 times as long as broad (n = 6), whereas in U. austriacalis the signum is 3.4-4.4 times as long as broad (n = 8) (Tab. 1). Udea donzelalis can furthermore be distinguished by the DNA Barcode from all other sequenced Udea species; the nearest neighbour is U. cretacea with 4.29% minimum p-distance.

Redescription.

Head. As for U. austriacalis , apart from: frons and vertex covered with cream-white to beige scales; labial palps covered with light brown scales, outer sides of labial palps’ second and third segment sometimes slightly darker with dirty light brown scales; maxillary palps approximately one third as long as labial palps, with beige to light brown apical scale tuft; antennal length approx. 60 % of forewing length in males, approx. 70 % in females.

Thorax. As for U. austriacalis , apart from: legs cream-white except for dark brown inner side of fore- and midlegs; hindleg proximal outer spur ca. 2/3 length of inner spur, distal spurs almost equal in length, outer slightly shorter.

Wings. Forewing length 12-13 mm in males, 8-10 mm in females. Males and females with one frenulum bristle. Female forewing with more acute apex due to the straight costa (distally curved in males). Forewing ground colour glossy cream-white, with maculation more or less prominent: a light brown streak parallel to the basal two thirds of the costa, distal discoidal stigma a diffuse brownish area, postmedial line brownish, arching around distal discoidal stigma, then turning basad until below distal discoidal stigma, sharply arching back outwards (the " Udea loop" typical for most species in the genus), then following the course of the arch in the postmedial line’s anterior part and meeting with the dorsum at about two thirds of the dorsum length; apical streak more or less pronounced, usually relatively broad; ends of veins on dorsum with minute dark dots; fringe light cream-white. Hindwing in both sexes cream-white to grey-brown, postmedial line and terminal band dark brown, can be fused into one broad band. Underside of forewing uniformly brown, sometimes with grey-grown strip along cell; underside of hindwing greyish white with a brown tinge, postmedial line brownish grey, rather diffuse; colour of external area as internal area, or brownish grey as postmedial line, with which it can form a broad band.

Abdomen. As for U. austriacalis .

Male genitalia. (Figs 29-33) As for U. austriacalis , apart from: juxta nearly rhombical to broad drop-shaped, apex sharply bifid with medial incision about one fifth of juxta length; ventral valva edge straight to slightly convex; elongate triangular, apically tapering, strongly sclerotised fibula directed towards distal sacculus apex, apical half narrowed to pointed, ventrad curved claw, ventral side of claw flat; right posterior phallus apodeme forming sclerotised spatulate lobe with medially protruding ridge containing three teeth of varying shape at posterior end.

Female genitalia. (Fig. 46) As for U. austriacalis , apart from: signum 4.1- to 5.1-times as long as broad (n = 6); length of auxillary signum 42-62 % of main signum length (n=6); length of antrum sclerotisation 1-1.5 times the antrum diameter.

Immature stages.

Unknown.

Distribution.

DNA data.

See Table 2. On BOLD, U. donzelalis is represented by BIN ADB6837. The five DNA barcoded specimens are identical in their DNA barcodes. The nearest neighbour is U. cretacea with 4.29 % minimum p-distance in the COI Barcode (see Tab. 3). The next-closest neighbour is U. rhododendronalis with a minimum interspecific COI p-distance of 4.76 %.

Remarks.

Lederer (1863) synonymised donzelalis with U. austriacalis , and following authors ( La Harpe 1864, Marion 1973, Leraut 1996) came to the same con clusion. However, Leraut (1996) mentioned that the specimens from the Pyrenees, conspecific with the revised U. donzelalis , differ from other specimens of U. austriacalis in their clearer maculation on the forewings in both sexes. Based on the investigation of the four syntypes of U. donzelalis , a lectotype and three paralectotypes are designated (see material examined).
