On some new or poorly-known millipedes from Chile and Argentina (Diplopoda

Abstract

A fresh collection of Diplopoda from Chile and Argentina appears to contain 16 identifiable species, mostly richly illustrated, among which four are new: Argentocricus iguazu sp.n. (Rhinocricidae, Spirobolida) from Argentina, as well as Semnosoma eskovi sp.n., Abatodesmus simplicior sp.n. and Anaulacodesmus bifidus sp.n. (all Dalodesmidae, Polydesmida) from Chile. The following new synonymy is established: Monenchodesmus inermis Silvestri, 1903 = Monenchodesmus inermis nahuelhuapiensis Schubart, 1954 = Monenchodesmus tiganus Chamberlin, 1957, syn.n. (the valid name the first). The species Anaulacodesmus lacustris Schubart, 1954, previously known only from the Andean parts of Argentina bordering on Chile, is recorded from Chile for the first time.
