Remarks.
The assessment of
C. variegata
as a
nomen dubium
by
Ruiz & Brescovit (2008)
is absolutely justified and will definitely not change anymore. Even, if the juvenile male
holotype
would be found in the future, it would be impossible to define this species, as the male copulatory organ is not developed in this specimen. A definite discrimination of
Corythalia
species, however, is not possible without the examination of copulatory organs of adult specimens. The present study has shown that colouration patterns, if at all, may help distinguish certain groups of species, but definitely not to recognise a particular species. Additionally, a certain degree of variation in coloura- tion is recognisable among different specimens of most species and especially the colouration of the opisthosoma depends on the nutritional state or the maturity of females (i.e. state of the oogenesis). Moreover,
Crane (1948)
had found out that the colouration of juvenile specimens often differ from that of adults. In
French Guiana
several other
Corythalia
species occur, e.g.
C. waleckii
,
C. luctuosa
,
C. spiralis
,
C. foelixi
Bayer
,
sp. nov.
,
C. fulgipedia
. It is not to exclude that the juvenile type of
C. variegata
is conspecific with one of these species. In any case, as the type specimen is juvenile, it is impossible to discriminate
C. variegata
from other
Corythalia
species based on the description and the illustration (
Fig. 67
) in
Caporiacco (1954)
.
