Specimens of a previously unrecorded collembolan species were found in a ﬁeld margin of a commercial dairyfarm near Christchurch, New Zealand. They were consistently observed apparently feeding on egg batches ofthe light brown apple moth Epiphyas postvittana, which were being used as bait to assess predation rate by poten-tial biocontrol agents. The collembolan specimens were identiﬁed as the European species Dicyrtoma fusca basedon published morphological descriptions of this species. DNA sequence data of the New Zealand specimens clus-tered with sequence data from GenBank of this species from Norway and England, conﬁrming that D. fusca pop-ulations in New Zealand originated from Europe. A GenBank sequence had previously identiﬁed a collembolanspecies from Estonia as this species, but its position in the phylogeny indicates that it is a different species. Somemorphological variations observed in arrangement of macrochaetae on the head were shown by sequence data tobe intraspeciﬁc differences only.
A new species and genus, Skadisotoma inpericulosa, is described from south-eastern Australia. It possesses some characters that are found in Tomoceridae, such as a long cylindrical dens that is medially bent and a mucro with at least six teeth of different sizes and three setae but in other characters it resembles an isotomid. In this it shows similarities to the Boreal genus Mucronia Fjellberg, but differs from it in the possession of spines on the dens and in some chaetotaxic characters.
