Remarks.
According to
Escalera (1914)
, the original description of
susicus
was based at least on
two specimens
(‘‘length. 5–7 mm’’) from
Agadir
, and deposited in the
MNCN
, Madrid. In the Collection Escalera there are
two specimens
(damaged by
Anthrenus
) of
Laparocerus
from
Mogador
collected in 1906, a different locality, hence not
syntypes
, and
one male
specimen in good conditions, with a printed locality label reading ‘‘Agadir’’, but no further identification label. This specimen was located misplaced in the Collection with other curculionids. Moreover, some of Escalera’s specimens went to Paris, apparently in the years 1968 and 1980. In the Museum National d’Histoire Naturelle there are
two specimens
labelled as ‘‘cotypes’’ of
Cyclobarus susicus
, both from
Agadir
, but with different sets of labels and mounted on different types of cards. One of the
syntypes
(
Figure 6A
), kept in Coll. Ruter (Muséum Paris, 1980), is a male of a
Laparocerus
and was studied by Ruter, who consequently transferred the species to that genus and provided a line drawing of its habitus (
Ruter 1945
). The second
syntype
(
Figure 6B
), kept in Coll. Hoffmann (Muséum Paris, 1968) is a
Cyclobarus
. It seems that Escalera described
susicus
based on specimens pertaining to different species and genera. The textual description applies exactly to the
Laparocerus
, but the only
syntype
that bears at least one handwritten label of Escalera [‘‘Agadir’’] is the
Cyclobarus
(
Figure 6B
, second label from top). To designate this latter specimen as the name-bearing type (
lectotype
) would have rather cumbersome implications: firstly, a redescription of
susicus
would be necessary; secondly,
Cyclobarus susicus
would enter in synonymy with
Cyclobarus mskalicus
Escalera, 1914
(J. Pelletier, personal communication); thirdly, a new name would be needed for the
Laparocerus
species
, despite the fact that it has been described as
Cyclomaurus tessellatus
Hustache, 1932
(as
Laparocerus
it enters in secondary homonymy with
Laparocerus tessellatus
(Brulle´, 1839). A more practical solution for stability is to exclude the
Cyclobarus
specimen, and to designate the
Laparocerus
male from
Agadir
kept in Madrid as
lectotype
of
susicus
Escalera, 1914
.
