Williboldiana new genus 
Type species: Willibaldiana paasi new species 
Description. (Figure 1) Labial palp two and a half the 
diameter of the eye, whitish grey; second segment 
strongly scaled, spatula shaped; head rough scaled with 
white greyish tipped scales; antenna fasciculate black 
and white ringed. Hind tibia whitish with more or less 
strongly blackish rings narrower closer to the tip of tibia; 
two pairs of rather long spurs. In hindwing vein M2 is 
approaching basally to CuAl and M3 is missing. 
Forewing with many fine costal strigula and a costal 
fold reaching 2/5th of the length; at the tornal area there 
is a reminiscence of a speculum where the outer line is 
present but only with a very week line of leaden 
glistening scales. 
Male genitalia (Figure 4). Uncus very week, reduced; 
socii rather broad, rounded; tegumen broad with slender 
pedunculi; valva very small and rather weak with a bigger 
rounded and hairy cucullus; at the dorsal edge of cucullus 
three long pointed thorns growing in size to the corner of 
cucullus; aedeagus long, narrow and tipped; it is more 
strongly sclerotised towards the tip; vinculum strong. 
Female genitalia (Figure 6). Papilla analis long and 
hairy; apophyses rather week and short; ostium very 
weekly developed or reduced; ductus bursa long, 
strongly sclerotised from bursa to just before ostium, 
where it is without sclerotisation and is narrowing; bursa 
rounded with two small signa and a central area with 
stronger wrinkles. 
Abdomen (Figure 8, IV. schmitzi n. sp.) has strongly 
sclerotised spiracles - one at each segment. 
Etymology. The genus is named after my good friend 
and provider of the specimens Willibald Schmitz.

Diagnosis. The species differs from the other 
Willibaldiana species by the much smaller size and the 
more whitish/grey ground colour of the forewing. The 
drawings are less stretched towards the tip of the wing 
than in the preceding species. In the male genitalia the 
species differs by having general smaller genitalia with 
smaller thorns and the hairs on the cucullus are much 
less pronounced; aedeagus is more tipped and shorter; 
socii are bigger and the following species has a short 
uncus. In the female genitalia the two signa are very 
small and not funnel shaped. The sclerotised spiracles - 
one in each segment of abdomen - are much smaller 
than in the following species. 
Description. Imago. (Figure 1) Wingspan 9-10 mm. 
Antenna fasciculate, strongly ringed white and black. 
Labial palp two and a half the diameter of the eye, 
whitish grey; second segment strongly scaled, spatula 
shaped; head rough scaled with white greyish tipped 
scales. Hind tibia whitish with more or less strongly 
blackish rings narrower closer to the tip of tibia; two 
pairs of rather long spurs. In hindwing vein M2 is 
approaching basally to CuAl and M3 is missing. Ground 
colour whitish suffused with irregular dark areas and 
spots and also powdered with very small orange-yellow 
scales. The basal blotch is dark irregular defined followed 
by a lighter area before some darker areas which are 
reminiscent of the median fascia; apical fascia darker 
irregular spotted. There is a reminiscence of a speculum 
where just the outer line is present but only with a very 
week line of leaden glistening scales and at the place for 
the inner spot there is a bright area. At costa several 
strigula dark and light and five of them are not divided. 
Cilia are light grey with a dark dividing line. Hindwing is 
light grey unicoloured and the fringes are without a 
dividing line.
