A new genus and two new species of Leiodinae from Chile, with keys to world genera of Sogdini and Leiodinae from Chile and Argentina (Coleoptera: Leiodidae)

Abstract

Anaballetus gen. nov., Anaballetus chilensis sp. nov. (tribe Sogdini) and Neohydnobius irregularis sp. nov. (tribe Pseudoliodini), both from Chile, are described and distinguished from related and similar taxa. A key for the identification of the described world genera of the tribe Sogdini is presented, and the placement of the new genus is discussed; it is considered most closely related to still-undescribed genera known from Australia and New Zealand. A key is also provided to all described species of Leiodinae known from Chile and Argentina. With the exception of Dietta Sharp, 1876, all of these genera and species of Leiodinae are endemic (precinctive) to Chile and southern Argentina.
