Abstract

The type material of all species presently assigned to the curculionid genus Laparocerus Schönherr, 1834, and described prior to 2006, is here compiled as an advance of the revision of the genus undertaken by the author. A total of 105 names of taxa of the species level are considered valid and 24 invalid. These later cases relate to homonyms or synonyms, of which the following seven are here newly established (n. syn.): chaoensis Uyttenboogaart, 1940 = vandeli Roudier, 1958; eliasenae Uyttenboogaart, 1929 = cymbula Roudier, 1957; escalerai Uyttenboogaart, 1937 = longehirtus Roudier, 1957; hirtus Wollaston, 1854 = doramasensis Uyteenboogaart, 1929; morio Boheman, 1834 = obesulus Desbrochers, 1904; sanchezi Roudier, 1951 = nitidirostris Roudier, 1951; and susicus (Escalera, 1914) = tessellatus (Hustache, 1932). Laparocerus incomptus (Wollaston, 1864), type species of the subgenus Amyntas Wollaston, 1865, is re‐established as a good species. Furthermore, Laparocerus wollastoni Heer, 1857 (a fossil species) and L. piceus Boheman, 1834 are considered nomina dubia. A total of 52 lectotypes have been designated, as well as neotypes for Omias tessellatus Brullé, 1839 and Lichenophagus incomptus Wollaston, 1864. Some photographs of type specimens and of the two neotypes are provided. Depositary collections and type locality information has been revised and completed as far as possible.

Highlights

The monographic study of the genus Laparocerus Schonherr, 1834, in which I have been involved for the last five years, covers a thorough field prospecting in Macaronesia and west Morocco in the mainland, the systematic revision of all known species, description of new taxa, biological aspects, and the phylogeography of the group based on molecular analysis

Summary

Introduction

The monographic study of the genus Laparocerus Schonherr, 1834, in which I have been involved for the last five years, covers a thorough field prospecting in Macaronesia (archipelagos of the Azores, Madeira, Selvagens, and Canaries) and west Morocco in the mainland (ca 20,000 exx), the systematic revision of all known species, description of new taxa, biological aspects, and the phylogeography of the group based on molecular analysis.The present contribution is an advance of the revision results, consisting of the study of the type material of all previously described species-level taxa (prior to 2006) that have been ascribed originally or subsequently to the genus Laparocerus, regardless of the fact thatCorrespondence: Antonio Machado, C/Chopin 1, 38208 La Laguna, Tenerife, Canary Islands, Spain.
