In the third supplement (N.O.S.T.: Reynolds and Cook, 1993), genera were assigned to 36 families recognized therein. Subsequent to the publication of that third supplement (noted also in the third paragraph of the main Prolegomenon page linked from the left navigator bar of this website), six new families have been established: Tumakidae {Righi, 1995; Stud. Trop. Andean Ecosystems 4(16): 600}, Parvidrilidae {Erséus, 1999; Proc. Biol. Soc. Wash. 112(2): 328}, * Rhinodrilidae {James, 2012; Zootaxa 3540: 67}, Tritogeniidae {Plisko, 2013; African Invertebrates 54(1): 79}, Kazimierzidae {Nxele and Plisko, 2016: African Invertebrates 57(2): 113}, and Arecoidae {James, Csuzdi & Brown, 2023: Zootaxa 5255(1): 421; type genus: Areco Righi, Ayres & Bittencourt, 1978}.
Four other families are now excluded: Kurenkovidae {Brinkhurst, 1989; Can. J. Zool. 67: 2736}, Lycodrilidae {Hrabě, 1982; Věstn. Česk. Spol. Zool. 46(3): 180}, Tubificidae {Erséus, C., M.J. Wetzel, and L. Gustavsson, 2008; Zootaxa 1744: 66–68}, and Lobatocerebridae {Nielsen, 2012. Animal Evolution. Third Edition. Oxford, University Press, p. 115}. Full citations for the publications in which the above new families have been defined are included on the References page linked from the left navigator bar of this website.
Accounts for new taxa described since publication of N.O.S.T. in 1993 (and those inadvertently omitted from N.O. and its three supplements, N.O.S.P., N.O.S.S., and N.O.S.T.) have been added to this on-line nomenclator. Although we have been diligent in our search for and access to publications in which taxa have been described as new to science, many have yet to be added – particularly the descriptions for new taxa that have been published in the lesser known scientific literature, or in books, symposia proceedings, and/or journals with inconsistent publishing schedules.
* Early in 2012, James (in James and Davidson, Invertebrate Systematics 26(2): 204–212), established a new family, Pontoscolecidae, into which several taxa in the family Glossoscolecidae s.s. were transferred based on analyses of 28S, 18S, and 16S gene sequencing of taxa in 14 families within the Crissiclitellata. A subsequent paper by James (2012, Zootaxa 3540: 67–68) noted that the name Pontoscolecidae James, 2012 is in fact synonymous with the much older but largely forgotten Rhinodrilidae Benham, 1890. Thus, please reference James’ 2012 Zootaxa paper for a listing of the genera now included in Rhinodrilidae.]
The table below includes the number of taxa (genera, subgenera, species, and subspecies) first described as new to science, by year; we also include re-validations for several taxa previously designated species dubia.

Please note that the tallies in each column for the most recent years continue to increase as accounts are prepared and added to NO2 pages; many accounts for newly described taxa in the years 2014–present remain to be added.
We encourage all users of this website to contact us with information for taxa that have not yet been included in this nomenclator, and to correct mistakes on any of the pages. We also encourage you to prepare the accounts of your newly described taxa for inclusion on the genus, subgenus, and species pages of this website, which will assist us in adding them quickly. Please send each of us PDFs of your papers in which descriptions, re-descriptions, and re-validations have been published – to assist us in the accurate updating and creation of accounts for inclusion in this nomenclator. Thank you; JWR & MJW.
