Cleopus verbasci
Dufour, 1843
Cleopus verbasci
was quoted by
Dufour (1843)
as being described by Fabricius, but the name had not been used in this combination by any previous author.
Fabricius (1787)
actually described
Curculio verbasci
[currently
Cionus
and synonymous with
C. tuberculosus
(Scopoli, 1763)
], which Dufour reported on the same page as
Cionus
. Certainly Dufour followed
Dejean (1821)
who cited a
Cionus verbasci
(surely the above Fabrician species) from “Paris”, and immediately below a
Cleopus verbasci
(attributed to “Meg.[erle] Rossi?” from “
Gal
.[lia] mer.[idionalis]”). Since, however, Dejean did not write any description, Dufour is the author of this species (
type
locality: Vallée d'Ossau, French Pirenees), as correctly reported by Desbrochers des
Loges (1893)
,
Zumpt (1933)
and
Klima (1934)
. This taxon was described by Dufour very briefly after some species of
Cionus
and quoted as being collected on
Verbascum
. Desbrochers des
Loges (1893)
placed
Cleopus verbasci
among the synonyms of
R. vestita
(
Germar, 1821
)
without explanation, a decision followed by
Zumpt (1933)
and
Klima (1934)
.
Péricart (1973)
reported that there are no
syntypes
of this taxon in Dufour's collection at MNHN, but stated that the synonymy with
R. vestita
is very doubtful on the basis of the host plant (
R. vestita
lives on
Antirrhinum majus
) and the brief description. We agree with Péricart's opinion and consider
Cleopus verbasci
as synonymous with
R. tetra
. This position is corroborated by the arguments reported below with regard to
Cleopus uncinatus
. Therefore, following the provisions of the Article 75 of the ICZN (1999), with the express purpose of clarifying taxonomic status of this taxon, we designate a
neotype
for
Cleopus verbasci
Dufour
which agrees with
R. tetra
. It is deposited at MNHN and has the following label data: “
France
, Bilhères d'Ossau,
4.VIII.2011
, sur
Verbascum blattariae
L., leg. P. Weill & J. Pelletier [printed on white card] /
Neotype
,
Cleopus verbasci Dufour
, des. R. Caldara 2011 [printed on red card]”. This specimen is a male, 3.0 mm long (rostrum excluded), in good condition and glued on a white rectangular card. The
type
locality of this taxon becomes now
France
, Pyrénées-Atlantiques, Bilhères d'Ossau.
It should be noted that the name
verbasci
Dufour
in the genus
Rhinusa
is a secondary homonym with
R. verbasci
(
Rosenschoeld, 1838
)
.
