Laparocerus squamosus
(Brulle´, 1839)
Otiorynchus squamosus
Brullé 1839
, p 71
.
Type locality.
Gran Canaria (northern side),
Canary Islands
.
Lectotype
: 1„, without head and prothorax, and only three legs.
Ventrites
and aedeagus glued on the same mounting card (by
A. Roudier
).
Webb
and
Berthelot
leg. (
ex litt.
).
MNHN
(
Coll. Générale
),
Paris
.
Paralectotypes
:
3♀♀
, much rubbed; some tarsi missing; two of them with ventrites on additional card.
The
specimens were originally pinned (pinhole on elytra).
Webb
and
Berthelot
leg.
MNHN
(
Coll. Générale
),
Paris
.
Remarks.
Brullé (1839)
did not mention the island of origin. The species inhabits Gran Canaria, as observed by
Roudier (1957a)
. From the list of carabid species reported by Brulle´, one can infer that in the case of Gran Canaria the insects were collected probably during two excursions; one in the vicinity of Las Palmas, and another more to the interior (Tafira, Santa Brígida?), both in the northern side of the island (cf.
Machado 1992
, p 266 footnote).
Laparocerus subnebulosus
(
Wollaston, 1854
)
Atlantis subnebulosa
Wollaston 1864
, p 337
.
Type locality.
El Monte
, Gran Canaria,
Canary Islands
.
Holotype
:
1♀
, slightly immature. Gran Canaria [E.M. or L.P.] El Monte or La Isleta, Spring 1858, leg. Wollaston (
ex litt.
) [Type] [
Atlantis
/
subnebulosa
/Woll. type]. NHM, London.
Remarks.
Wollaston was not sure about the
type
locality, either La Isleta or El Monte. Knowing the ecology of the species, El Monte seems to me more plausible, while La Isleta lies just too low.
Wollaston (1865
, p 337) established the subgenus
Canopus
for four species of Canarian
Atlantis
,
A. subnebulosa
being the first on the list. I fix this species as the
type
for
Canopus
Wollaston, even though the name is already occupied by
Canopus
Fabricius, 1803
,
Canopus
Montfort, 1808
,
Canopus
Rafinesque, 1840
,
Canopus
Walker, 1855
, and
Canopus
Felder, 1861
.
Alonso-Zarazaga and Lyal (1999)
resurrected the name
Amyntas
Wollaston, 1865
for the Canarian subgenus (see
Laparocerus incomptus
).
Laparocerus subopacus
Wollaston, 1865
Laparocerus subopacus
Wollaston 1865
, p 322
, Appendix p 52.
Type locality.
Monte Forte (5
El Cedro
),
La Gomera
,
Canary Islands
.
Lectotype
: 1„ (red card-line), La Gomera, Monte Forte, Messrs Crotch leg. (
ex litt.
). [Type] [
subopacus
, W.]. NHM, London (
Figure 4A
).
Paralectotypes
: not yet localized.
Perhaps
in the third
Wollaston Collection
(mainly material from the Messrs Crotch), deposited in the
California Academy of Sciences
(see
Kavanaugh 1979
)
.
Remarks.
In the description, Wollaston did not mention the remarkable lateral dents of the abdomen (see
Figure 4A
). He may have considered them a deformation, but it is the natural habitus of the insect. In Junk and Schenkling’s catalogue (
Lona 1938
) there are two entries for this species: first as
Laparocerus (Laparocerus) opacus
(p 348)—an incorrect subsequent spelling—and second, as
L. subopacus
(p 349).
