(Figs 1-2 & 6-7)  
 Material examined: Holotype ♀ (fig. 1) Spain: Canary Islands, La Gomera: Vallehermoso, 300 m. 15.- 16.iv.1998 (K. Larsen leg., gen. prep. 4184 ♀ KL). Paratype (fig. 2) ♀ Spain: Canary Islands, La Gomera: Hermigua, El Convento, 600 m 6.-13.iv.2007, leg. W. Losert (coll. KL).   
From litt. 3 ♀ Hermigua, Agulo, 30.iv.- 6.5.1965 leg. J. Klimesch (Klimesch, 1987).  
 Description   
Female (Fig. 1-2): Wingspan 10 – 12 mm. Frons and head dark brown with raised scales. Antenna half the length of forewing and black in colour. Labial palpus short and grey. Thorax and abdomen dark brown, with the underside lighter in colour. Legs light greyish-yellow. Spurs with a few dark spots.  
Forewing lanceolate, apex pointed. Termen indented and curved. Ground colour grey and shadowy, in the first half of the costa and forming a dividing light grey fascia from the middle of costa to the dorsum before the speculum. A large, sharply defined blackish dorso-basal blotch, oblique towards the light dividing line. Median fascia blackish, triangular pointing at apex. Four pairs of white costal strigula in outer half with blackish dividing marks. The narrow area between the median fascia and the strigula is light brown. The speculum is large, grey and v-shaped towards the costa. In the middle a white-ringed blackish dot. Two tiny, white post-apical strigula. Cilia greyish-yellow with an inconspicuous dividing line. Hindwings grey-brown with darker cilia.  
Underside of wings is grey with visible strigula at costa of forewing.  
Female genitalia (Fig. 6 & 7): colliculum short, sterigma semi-circular, large, ostium weak, lamella postvaginalis large, divided, tapering distally, ductus bursae and corpus bursae very weak and hardly visible, two triangular signa, one twice as large as the other.  
Male: unknown.  
 Biology: Not known except for the collecting dates and localities: five specimens 6.iv.-6.v on La Gomera: Hermigua, Agulo and Vallehermoso. The three localities are on the northern slopes of the island with mostly rather dry shrubland vegetation.   
 Etymology: The species is named after the famous Austrian entomologist Josef Klimesch, who was the first to discover this taxon.   
 Diagnosies: The species is easily distinguished from A. comptana (fig. 3) by the distinct blackish markings including the white-ringed black dot in the large speculum and from A. sparulana (fig. 4) by the shape of the dorso-basal blotch. In the female genitalia the differences when compared to A. comptana (fig. 8) are quite obvious, especially the smaller size of the colliculum and the large semi-circular sterigma is characteristic. The sterigma of A. sparulana (fig. 9) is very large and rounded and not semi-circular as in A. klimeschana.   
 Faunistic report   
 A specimen of Ancylis comptana (fig. 5) is reported from the Balearic island of Mallorca.   
SPAIN: Mallorca, Alcudia, s’Albufereta, 20.-21.ix.2009 (K. Larsen leg. et coll., gen. prep. 4439 ♀ KL).  
 The specimen from Mallorca superficially looks like A. comptana (Fröl.), although rather small – wingspan 10 mm. It is figured here for comparison. There are slight differences in the genitalia, but more material would be needed to document a different status of this taxon.
