Updating the New Zealand checklist of Collembola: A synonymy and new combinations

The New Zealand checklist of Collembola was prepared 10 years ago but only published in 2012 (Greenslade P 2012. Collembola. In: Gordon DP ed. The New Zealand inventory of biodiversity: a species 2000 symposium review. Volume 1, Animalia. Christchurch, Canterbury University Press. Pp. 237-243). Since 2004, a number of changes in the species list, both additions and deletions, have been published but they are scattered in disparate journals. Also, new synonymies and new combinations have become evident. Here, I gather these findings together in a single article, thus making them available. I synonymise Sminthurus multidentatus with S. viridis and remove the subfamily Uchidanurinae from the list, transferring its New Zealand and Australian species to the subfamily Pseudachorutinae. Other already published new records, corrected identifications and new combinations are listed here including some additions to the description of the type and only species Clavaphorura septemseta of its New Zealand endemic genus. The total number of species known from New Zealand is now 350, with 101 genera. The number of families remains at 18 but the number of subfamilies falls from six to five. I document them here with a new synonym and combination.
