| Abstract: | Summary
Stammerinema soricis (Tiner, 1951) is reported fromSorex araneus L. from a new geographic locality, Sologne, France. Comparison of the ontogenesis of the cephalic structures of this species with two other acuariids of mammals,S. suffodiax Beveridge & Barker, 1975 andS. thapari (Teixeira de Freitas, 1953), shows that these three species, formerly included in the same genus, represent three distinct genera:Stammerinema Osche, 1955, parasitic in holarctic insectivores;Antechiniella n. g. parasitic in Australian marsupials and rodents; andSkrjabinoclava Sobolev, 1943, parasitic in neotropical carnivores and in birds. The two generaStammerinema andAntechiniella belonging to different subfamilies of the Acuariidae, are derived from acuarioids which have evolved mainly in birds, hosts which harbour ancestral forms. ac]19850610 |
