Aa. Lanteri et Nb. Diaz, SYSTEMATIC STUDY AND CLADISTIC-ANALYSIS OF THE GENUS ARAMIGUS HORN (COLEOPTERA, CURCULIONIDAE), Transactions of the American Entomological Society, 120(2), 1994, pp. 113-144
Aramigus Horn (Entiminae: Brachyderini) here includes seven species: A
. pilosus Lanteri sp. nov., A. curtulus (Hustache) comb. nov., A. plan
ioculus Lanteri sp. nov., A. globoculus Lanteri sp. nov., A. intermedi
us Lanteri sp. nov., A. conirostris (Hustache) and A. tessellatus (Say
) (syn. nov. with A. durius (Germar), A. pallidus Horn, A. viridipalle
ns (Hustache), A. biseriatus (Hustache) and A. santafecinus (Lanteri))
. The last is a complex species with bisexual populations and partheno
genetic lineages, some of which correspond to the synonyms of A. tesse
llatus, and are here treated as morphotypes. The genus is redescribed
to include newly discovered variation and its relationships with other
genera are discussed. All species are described and five morphotypes
of A. tessellatus are diagnosed. A cladistic analysis resulted in four
most parsimonious cladograms in which A. pilosus is always basal; A.
curtulus and A. planioculus are sister taxa or form a trichotomy with
the remaining species; A. globoculus and A. intermedius are in phyloge
netic sequence or are sister species; and the pair tessellatus-coniros
tris is always present and terminal. The paper includes two keys (one
for the species of Aramigus and another, for the morphotypes of A. tes
sellatus); outlines of all species; illustrations of female and male g
enitalia; and distribution map to the South American species.
