Abstract

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Collection and specimen data from the new QVMAG specimen lots have been archived in Darwin Core format together with a KML file of occurrences.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.

Keywords

Polydesmida; Dalodesmidae; Polyzoniida; Siphonotidae

Introduction

The millipede fauna of southern South America is poorly known Golovatch 2014, and many named species are known only from their type localities. While working as a forester in 1983 I had the opportunity to visit native forests in southern Chile and to opportunistically sample myriapods. Centipedes in the samples were later deposited in the Tasmanian Museum and Art Gallery (TMAG) in Hobart, Tasmania, and millipedes in the Queen Victoria Museum and Art Gallery (QVMAG) in Launceston, Tasmania. I recently re-examined the QVMAG samples and was able to identify most of the millipedes to species, and to register them as QVMAG specimen lots. Collection and specimen data for these registered lots have now been archived and are publicly available through Zenodo.

General description

Purpose: 

The occurrence data are being made available to assist future studies of the millipede fauna of southern South America. The specimen lots are available for loan from QVMAG.

Sampling methods

Sampling description: 

Millipedes were opportunistically hand-collected by the author during visits to forests in Chile's Llanquihue and Osorno provinces in 1983. Most were found in or under rotting logs. Millipedes were placed in ca 75% methylated spirits in Chile and transferred to 75-80% ethanol at QVMAG. Using my 1983 field notes, Google Maps, Google Earth and online maps of southern Chile, I georeferenced the collecting localities in 2017 to a spatial uncertainty of ±1000 m or less in most cases.

Additional information

The 31 occurrence records in the Darwin Core Archive list 13 millipede taxa from 16 sites in southern Chile. Ten of the 13 taxa (24 samples) are named species of Dalodesmidae (Polydesmida), one sample contains a possibly new species in the genus Tsagonus Chamberlin, 1957 (Dalodesmidae) and two samples contain only unidentifiable female dalodesmids. The last taxon (six samples) is Siphonotidae (Polyzoniida).

The Dalodesmidae identified to species are: Abatodesmus velosoi Demange & Silva, 1971, Anaulacodesmus bifidus Golovatch, 2014, A. carinobtusus Silvestri, 1903, A. levissimus Attems, 1898, Pleonaraius pachyskeles Attems, 1898, Semnosoma eskovi Golovatch, 2014, Trienchodesmus gayanus (Gervais, 1847), Tsagonus muermo Chamberlin, 1957, T. nahuelbutae Chamberlin, 1957 and T. osorno Chamberlin, 1957. A male Tsagonus from forest at Lago San Antonio in the south of Chiloé island is close to T. silvestrii Demange & Silva, 1976 but may be a new species.

The Siphonotidae are tentatively referred to Burinia, following Golovatch 2014, who refers all indigenous Chilean Polyzoniida to that genus.
