ABSTRACT. The mating position is described and illustrated for the first time in Peloridiidae. Peloridium hammoniorum Breddin, 1897 from Chile and Hemiodoecus leai China, 1924 from Tasmania mate in the side-by-side (V-shaped) position, where the tips of male and female abdomens are actually in a female-above position (the female’s posterior held between the male’s genitalia below and his tegmina above). Such mating position, common in Psyllomorpha, Auchenorrhyncha and Heteroptera, is likely primitive for Hemiptera.
KEY WORDS: relict, Chile, Tasmania, moss bugs, Auchenorrhyncha, Homoptera, Heteroptera, phylogeny, genitalia, copulation.
