Remarks.
The species was described by Boheman based on a single female labelled as from Lusitania (5
Portugal
); however, Gyllenhall is often cited as author. I have seen specimens of
L. azoricus
Drouet
labelled as
L. piceus
in several collections (Coll. Stierlin, Osella, Poncy, etc.). Furthermore,
Marseul (1872
, p 548) placed the species with a question-mark as synonym of
L. vespertinus
(
Wollaston, 1854
)
and it is recorded identically in
Winkler (1932
, p 1448), even though
L. piceus
Boheman, 1834
would have priority over
L. vespertinus
(
Wollaston, 1854
)
, as posteriorly recognized by
Schmitz (1898
, p 154) in his list of Madeiran coleoptera. It has been registered in several catalogues (
Jacquelin du Val 1855
;
Lacordaire 1863
;
Lona 1938
, etc.) as from
Portugal
, and only
Lundblad (1958
, p 485) assumes that the locality label ‘‘Lusitania’’ must be an error as in the case of
L. morio
, equally described by Boheman on a specimen provided by Falderman. Consequently, I assume the island of
Madeira
as the locality where the type really originated. The
holotype
of
L. piceus
is kept in Stockholm. It is a rubbed female specimen that resembles
L. noctivagans
(
Wollaston, 1854
)
, but could equally be assigned to
L. lauripotens
(
Wollaston, 1854
)
. Females of this group of
Laparocerus
(
L. vespertinus
, included) are not always easy to separate. Therefore I propose to consider
L. piceus
, a
nomen dubium
.
