Laparocerus squamosus, Brulle sensu Wollaston, 1864

Machado, Antonio, 2006, The type material of the species of Laparocerus Schönherr, 1834 (Coleoptera, Curculionidae, Entiminae), Journal of Natural History 40 (35 - 37), pp. 2001-2055 : 2037-2038

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).
