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databases contain omissions and errors, including those resulting from data entry mistakes and from the use of outdated or incorrect data sources.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. NEW INFORMATION: Here I describe a publicly available compilation of 3829 of my own collecting events over a 48-year period in Australia. Each record contains a unique combination of date, georeferenced location and location notes.

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

Tasmaniosoma armatum Verhoeff, 1936 and T. orientale 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. Two gonopod variants of T. orientale also appear to be parapatric.

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

Kebodesmuszonarius gen. nov. et sp. nov. is only known from a small area on the Great Western Tiers in northern Tasmania, Australia, and like species of Paredrodesmus 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.

An archived taxonomic website: Millipedes of Australia.

The taxonomic parts of the privately maintained Millipedes of Australia website (2006-2019), now offline, have been archived in Zenodo and are no longer being updated.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

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

Lissodesmuspiscator sp. nov. differs from the 30 previously described Lissodesmus 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.

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

Lissodesmus nivalissp. n. 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 Lissodesmus 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. The type status of specimen records did not change with name changes, resulting in confusion as to the name with which a type was associated. Data losses of up to 100% were found after processing in some fields, apparently due to programming errors. The taxonomic usefulness of occurrence records could be improved if aggregators included both original and the processed taxonomic data items for each record. It is recommended that end-users check original and processed records for data loss and name replacements after processing by 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.

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. Tasmanocambala is erected for the three Tasmanian cambalids, T.greeni gen. n., sp. n. (type species), T.tasmanica sp. n. and T.taylori sp. n. 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 Talomiusweldensis gen. n., sp. n. is described from a single site in Tasmania's southern mountain district. The new species is unusual among the Australian Iulomorphidae in having a fully-developed, ambulatory leg 1 in the male, and small, compact gonopods.

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. These compounds have not been detected before in millipede defensive secretions. This report is the first on species of the suborder Dalodesmidea (Polydesmida), a dominant component of the soil and litter fauna of the temperate regions of the Southern Hemisphere.

Annotated catalogue of South American Dalodesmidae (Diplopoda, Polydesmida).

All published names for genera and species of South American Dalodesmidae are presented with annotated synonymies. Semnosoma chilense (Silvestri, 1903) comb. nov. is introduced for the "orphan" species Iulidesmus chilensis Silvestri, 1903.

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

Tridactylogonus warrenbenensissp. n. is described from Warrenben Conservation Park at the southern end of the Yorke Peninsula in South Australia. Like T. obscurus Jeekel, 1982 and T. rugosissimus 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 Amastigogonus Brölemann, 1913 from Tasmania, Australia (Diplopoda, Spirostreptida, Iulomorphidae).

Amastigogonus insularissp. n. 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 Amastigogonus species. The new species differs from the 10 previously described species of Amastigogonus 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.

Iulomorphid millipedes (Diplopoda, Spirostreptida, Iulomorphidae) of Tasmania, Australia.

Tasmanian Iulomorphidae are here assigned to the genera Amastigogonus Brölemann, 1913, Atelomastix Attems, 1911 and Equestrigonusgen. n. Descriptions or redescriptions are given for Amastigogonus danpicolasp. n., Amastigogonus elephassp. n., Amastigogonus fossuliger Verhoeff, 1944, Amastigogonus hardyi (Chamberlin, 1920), Amastigogonus hellyerisp. n., Amastigogonus michaelsaesp. n., Amastigogonus orientalissp. n., Amastigogonus peninsulensissp. n., Amastigogonus tasmanianus Brölemann, 1913 (type species of Amastigogonus), Amastigogonus verreauxii (Gervais, 1847), Atelomastix bonhamisp. n., Atelomastix smithisp. n. and Equestrigonus tasmaniensisgen. n., sp. n. The synonymy of Amastigogonus nichollsii Verhoeff, 1944 with Amastigogonus hardyi is accepted, and lectotypes are designated for Amastigogonus nichollsii and Amastigogonus tasmanianus.

A new genus and species of dalodesmid millipede from New South Wales, Australia (Diplopoda, Polydesmida, Dalodesmidae).

Cernethiainopinata gen. n., sp. n. is described from highland New South Wales. Like other dalodesmids the new species has numerous sphaerotrichomes on the legs of adult males, but Cernethiainopinata sp. n. shares several character states with Tasmanian species in the genera Noteremus Mesibov, 2009, Paredrodesmus Mesibov, 2003 and Procophorella Mesibov, 2003, which lack sphaerotrichomes and have not yet been assigned to family within the suborder Dalodesmoidea.

A new genus and species of native exotic millipede in Australia (Diplopoda, Polydesmida, Paradoxosomatidae).

Taxidiotisomaportabile gen. n., sp. n. is described from scattered populations in New South Wales, Victoria and Tasmania, Australia. Populations of Taxidiotisomaportabile in Victoria, Tasmania and parts of New South Wales occur in urban, suburban and agricultural areas, with no collections of the species in natural habitats in the same district. Taxidiotisomaportabile is likely to be a native exotic species whose home range is in eastern New South Wales.

Redescription of Brochopeltismjoebergi Verhoeff, 1924 and description of a second Brochopeltis species from Australia (Diplopoda, Polydesmida, Paradoxosomatidae).

Brochopeltismjoebergi Verhoeff, 1924 is redescribed from type and new material, a lectotype is designated and Brochopeltismjoebergiqueenslandica Verhoeff, 1924 is synonymised with Brochopeltismjoebergi. Brochopeltismediolocus sp. n. is the first native paradoxosomatid described from Australia's Northern Territory.

Three new species of Tasmaniosoma Verhoeff, 1936 (Diplopoda, Polydesmida, Dalodesmidae) from northeast Tasmania, Australia.

The small-range millipedes Tasmaniosomaanubis sp. n., Tasmaniosomainterfluminum sp. n. and Tasmaniosomanicolaus sp. n. are described, and the colour of live Tasmaniosomabarbatulum Mesibov, 2010 is documented.

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.
