Revision of the enigmatic South African Cryptolaryngini (Coleoptera, Curculionidae), with description of a new genus and twenty-two new species

The weevil genus Cryptolarynx Van Schalkwyk, 1966 is endemic to the Northern and Western Cape provinces of South Africa. two previously known species genus, C. vitis (Marshall, 1957) estriatus 1957), have an aberrant globular body head shape, which has made it difficult place into classification systems Curculionoidea. This paper presents description 21 new from Africa (C. subglaber Haran sp. nov., squamulatus muellerae hirtulus robustus namaquanus carinatus variabilis pyrophilus pilipes armatus falciformis oberprieleri spinicornis cederbergensis homaroides marshalli endroedyi oberlanderi san luteipennis nov.) one species, Hadrocryptolarynx major gen. et also A redescription provided incorporate characters species. plant Oxalis (Oxalidaceae) recorded as larval host for several their larvae develop in subterranean bulbs members egg, larva pupa are described. confirm that Cryptolaryngini early-diverging group Curculionidae, with a placement among taxa currently classified subfamily Brachycerinae sensu lato, although exact taxonomic position remains unresolved, some characters, pupal ones, suggest close relationship between Stenopelmus Schoenherr.
