Abstract
The genus Aphanommata in the Old World is reviewed. Aphanommata kuscheli sp. nov. from São Nicolau and A. strakai sp. nov. from Fogo (both Cape Verde islands) are described. Aphanommata euphorbiarum (Wollaston, 1867) from Santo Antão in the Cape Verde islands is redescribed and its lectotype is designated. All three Aphanommata species from the Cape Verde islands as well as A. filum (Mulsant and Rey, 1859) from Old World are diagnosed, illustrated, and keyed. Mature larva of A. kuscheli sp. nov. is described, larval morphology is discussed and the current state of knowledge about immature stages of Cossoninae is summarized. Vertical and inter-insular distributional pattern of Cape Verde Aphanommata and Pselactus is reviewed and discussed.
Highlights
Islands and archipelagos are important for biodiversity because they host many threatened species and because they are biodiversity hotspots due to their high levels of endemism [1,2]
The Cape Verde Archipelago consists of ten main islands and several islets located between 550 and 800 km west of the Senegal coast, all the islands are volcanic in origin
The aim of this paper is to review the Cape Verde members of the genus Aphanommata
Summary
Islands and archipelagos are important for biodiversity because they host many threatened species and because they are biodiversity hotspots due to their high levels of endemism [1,2]. The Cape Verde Archipelago consists of ten main islands and several islets located between 550 and 800 km west of the Senegal coast, all the islands are volcanic in origin. Since that time, only limited data were accumulated about biology, larvae, evolution, distribution and the phylogenetical relationship of beetle taxa endemic to the archipelago [4,5,6,7,8,9]. Weevils are not an exception and recent field research produced a significant amount of undescribed endemic species which can shed light on the history of this group within the archipelago [8,9]. The genera Dinas Wollaston, 1867 and Pselactus Broun, 1886 were the only weevil genera with more than one species within the archipelago. Biological notes based on original observations are limited to the collecting notes for several genera made by Wollaston [3]
