On the basis of several Ö and ç specimens collected by the authors in northern
Norway in 1982 it is stated that Clepsis mehli (Opheim, 1964) is a separate and
valid species. In 1964 Opheim described mehli on the basis of a single specimen
from northern Norway, but later Razowski (1979) changed its status to
subspecies rank of the Japanese species Clepsis insignata Oku, 1963.
Imago and genitalia of both sexes of the Clepsis species most related to mehli
namely C. tannuolana Kostjuk, 1973 andC. insignata are figured and compared.
C. mehli is more closely related to tannuolana than to insignata. Remarks on the
variation and habitat of mehli are given.
The description of Clepsis mehli (Opheim, 1964) was based on a single
male from northern Norway: Fn : Vardo, 20.VÜ.1 962 (R. Mehl, coll.
Zoological Museum, Oslo). It was described in the genus Epagoge Hb.
(Opheim, 1964). The second specimen of mehli, also a male, was found
in northern Norway as well: Fi: Rafsnes, primo.vii.1979 (J. Itämies)
Razowski (1979), when revising the genus Clepsis Guenée, transferred
mehli to Clepsis and included it in his unicolorana group. He also
provisionally synonymized it with the Japanese species, C. insignata Oku,
1963, giving it status as a subspecies of insignata.
In 1982 the authors collected a large series of mehli both males and the
hitherto unknown female in a few localities near Alta in northern
Norway : Fi : Rafsnes and Kvenvik and Fv : Kviby and Laukvik. This
gave us an opportunity to study the taxonomic relationship between mehli
and its relatives.
The species in the unicolorana group are all very similar with respect to
the morphology of the male genitalia (Razowski, 1979). The female
genitalia usually offer more useful characters. Examination of the female
