An Australian collector's authority file, 1973-2020.

Background: Biodiversity databases contain omissions and errors, including those resulting from data entry mistakes and from the use of outdated or incorrect data sources. Some of these omissions and errors can be minimised by the use of authority files, such as expert-compiled taxonomic name databases. However, there are few publicly available authority files for collecting events, and the "where", "when" and "by whom" of specimen data are typically entered into biodiversity databases separately and directly, item by item from specimen labels.

A new genus and species of narrow-range millipede (Diplopoda, Polydesmida, Dalodesmidae) from Tasmania, Australia.

is only known from a small area on the Great Western Tiers in northern Tasmania, Australia, and like species of Mesibov, 2003 has no detectable paranota on the diplosegments. The gonopod telopodite of the new species is divided into a large, lateral, cowl-like structure, a solenomere and a medial branch with three processes.

A second remarkable case of parapatry in a Tasmanian millipede genus (Diplopoda, Polydesmida, Dalodesmidae).

Verhoeff, 1936 and Mesibov, 2010 are parapatric in northeast Tasmania, Australia. The parapatric boundary is ca 50 km long and mainly follows streamlines. Three sections of the boundary were intensively sampled.

An archived taxonomic website: .

The taxonomic parts of the privately maintained website (2006-2019), now offline, have been archived in Zenodo and are no longer being updated. Core taxonomic information about the Australian millipede fauna is now available on , a global taxonomic resource for millipedes. Most of the locality records for named, native Australian millipedes formerly available as downloads on the website are now accessible through the Atlas of Living Australia and the Global Biodiversity Information Facility.

A new and cryptic species of Chamberlin, 1920 (Diplopoda, Polydesmida, Dalodesmidae) from Tasmania, Australia.

differs from the 30 previously described species in the form of the femoral process of the gonopod telopodite, which is tripartite with an erect distal branch and two posteromedially curving basal branches. Despite careful searching, the new species has only been collected by pitfall trapping and may have a very small range in the northwest corner of the Central Plateau in Tasmania, Australia.

Cambaloid millipedes of Tasmania, Australia, with remarks on family-level classification and descriptions of two new genera and four new species (Diplopoda, Spirostreptida).

The Southern Hemisphere cambaloid millipede genera are here assigned or re-assigned to the families Cambalidae Bollman, 1893 and Iulomorphidae Verhoeff, 1924. is erected for the three Tasmanian cambalids, (type species), and The new genus is distinguished by a thin, transverse tab at the tip of the anterior gonopod telopodite with a comb of setae immediately behind the tab. The iulomorphid is described from a single site in Tasmania's southern mountain district.

A new, alpine species of Chamberlin, 1920 from Tasmania, Australia (Diplopoda, Polydesmida, Dalodesmidae).

is described from 1450-1550 m elevation on the treeless, alpine Ben Lomond plateau in northeast Tasmania, Australia. The new species is distinguished from all other Tasmanian and Victorian species by a unique combination of gonopod telopodite features: solenomere without a pre-apical process, tibiotarsus Y-shaped, femoral process L-shaped with forked tips, prefemoral process with a long comb of teeth below an irregularly dentate apical margin, and a roughened "shoulder process" near the base of the prefemoral process.

An audit of some processing effects in aggregated occurrence records.

A total of ca 800,000 occurrence records from the Australian Museum (AM), Museums Victoria (MV) and the New Zealand Arthropod Collection (NZAC) were audited for changes in selected Darwin Core fields after processing by the Atlas of Living Australia (ALA; for AM and MV records) and the Global Biodiversity Information Facility (GBIF; for AM, MV and NZAC records). Formal taxon names in the genus- and species-groups were changed in 13-21% of AM and MV records, depending on dataset and aggregator. There was little agreement between the two aggregators on processed names, with names changed in two to three times as many records by one aggregator alone compared to records with names changed by both aggregators.

A replacement name for Dalodesmus sakalava (de Saussure Zehntner, 1901) (Diplopoda: Polydesmida: Dalodesmidae).

Polydesmus (Pterodesmus) voeltzkowi nom. nov. is proposed as a replacement name for Polydesmus (Pterodesmus) sakalava de Saussure Zehntner, 1901, now Dalodesmus sakalava (de Saussure Zehntner, 1901), a junior primary homonym of Polydesmus sakalava de Saussure Zehntner, 1897.

The Chemistry of Some Dalodesmidean Millipedes from Tasmania (Diplopoda, Polydesmida).

Millipedes (Diplopoda) are well known for their toxic or repellent defensive secretions. As part of a larger investigation, we describe the chemical constituents of 14 species of Tasmanian millipedes in seven genera. Six species in the genus Gasterogramma were found to produce acyclic ketones, including the pungent unsaturated ketones 1, 2, and 6, and the novel (rel-3R,5S,7S)-3,5,7-trimethyl-2,8-decanedione (7b), for which the stereoconfiguration was established by stereoselective syntheses of pairs of isomers.

A new species of Jeekel, 1982 from South Australia (Diplopoda, Polydesmida, Paradoxosomatidae).

is described from Warrenben Conservation Park at the southern end of the Yorke Peninsula in South Australia. Like Jeekel, 1982 and Jeekel, 2002, the new species has prominent cellular sculpturing on the prozonites and granulose sculpturing on parts of the metazonites. Unlike its congeners and most species in the subfamily Australiosomatinae, the new species lacks a femoral process or tubercle on male leg 1.

A new and unusual species of Brölemann, 1913 from Tasmania, Australia (Diplopoda, Spirostreptida, Iulomorphidae).

is described from Schouten and Tasman Islands off the east coast of Tasmania, and a key is presented for the identification of males of Tasmanian species. The new species differs from the 10 previously described species of in having a reduced coxite process on the anterior gonopod.

New records for millipedes from southern Chile (Polydesmida: Dalodesmidae; Polyzoniida: Siphonotidae).

Background: Millipedes from 1983 collections by the author in southern Chile have been identified and registered as specimen lots at the Queen Victoria Museum and Art Gallery (QVMAG) in Launceston, Tasmania.

New Information: Collection and specimen data from the new QVMAG specimen lots have been archived in Darwin Core format together with a KML file of occurrences. The 31 occurrence records in the Darwin Core Archive list 13 millipede taxa from 16 sites in Llanquihue and Osorno provinces, Chile.

The Australian millipede Dicranogonuspix Jeekel, 1982 (Diplopoda, Polydesmida, Paradoxosomatidae): a species with and without paranota.

Dicranogonuspix Jeekel, 1982 occurs in Victoria and Tasmania, Australia, including the islands in eastern Bass Strait between the two States. There is only slight gonopod variation across this range, but Dicranogonuspix populations with and without paranota are separated in Bass Strait by the ca 50 km-wide gap between the Kent and Furneaux Groups of islands.

A dataset for examining trends in publication of new Australian insects.

Australian Faunal Directory data were used to create a new, publicly available dataset, nai50, which lists 18318 species and subspecies names for Australian insects described in the period 1961-2010, together with associated publishing data. The number of taxonomic publications introducing the new names varied little around a long-term average of 70 per year, with ca 420 new names published per year during the 30-year period 1981-2010. Within this stable pattern there were steady increases in multi-authored and 'Smith in Jones and Smith' names, and a decline in publication of names in entomology journals and books.

Hoplatessara luxuriosa (Silvestri, 1895) (Diplopoda, Polydesmida, Paradoxosomatidae) is native to Australia, not New Guinea.

Hoplatessara luxuriosa (Silvestri, 1895) is partly redescribed and illustrated. Its native range is shown to be in the cool-climate uplands of New South Wales, Australia. H.

New species of Agathodesmus Silvestri, 1910 from Australia (Diplopoda, Polydesmida, Haplodesmidae).

The genus Agathodesmus Silvestri, 1910 is speciose and widespread in high-rainfall parts of eastern Australia. In addition to the type species Agathodesmus steeli Silvestri, 1910 and Agathodesmus johnsi Mesibov, 2009 from New South Wales and Agathodesmus bucculentus (Jeekel, 1986) from Queensland, the following 18 new species are recognised: Agathodesmus adelphus sp. n.

A specialist's audit of aggregated occurrence records.

Occurrence records for named, native Australian millipedes from the Global Biodiversity Information Facility (GBIF) and the Atlas of Living Australia (ALA) were compared with the same records from the Millipedes of Australia (MoA) website, compiled independently by the author. The comparison revealed some previously unnoticed errors in MoA, and a much larger number of errors and other problems in the aggregated datasets. Errors have been corrected in MoA and in some data providers' databases, but will remain in GBIF and ALA until data providers have supplied updates to these aggregators.

Known unknowns, Google Earth, plate tectonics and Mt Bellenden Ker: some thoughts on locality data.

Latitude/longitude data in locality records should be published with spatial uncertainties, datum(s) used and indications of how the data were obtained. Google Earth can be used to locate sampling sites, but the underlying georegistration of the satellite image should be checked. The little-known relabelling of a set of landmarks on Mt Bellenden Ker, a scientifically important collecting locality in tropical north Queensland, Australia, is documented as an example of the importance of checking records not accompanied by appropriately accurate latitude/longitude data.
