DNA barcoding of euryglossine bees and the description of new species of Euhesma Michener (Hymenoptera, Colletidae, Euryglossinae)

Abstract

This paper launches an open access DNA barcoding project “AUSBS” under the (BOLD)Barcoding of Life Datasystems . The aims of the project are to help scientists who lack the necessary morphological knowledge to identify known species using molecular markers, to aid native bee specialists with the recognition of species groups that morphologically are difficult to define, and, eventually, to assist with the recognition of new species among known species. Using integrative taxonomy, i.e. morphological comparison to type specimens in Australian museum collections combined with phylogenetic analysis of a fragment of the (mtCOI)mitochondrial DNA cytochrome c oxidase subunit I gene sequences led to the recognition of four new species of Euhesma Michener (Hymenoptera: Colletidae: Euryglossini) collected during intensive surveys in remote Australian conservation areas, which are described. The new species are Euhesma micans, Euhesma lyngouriae, and Euhesma aulaca in a species group associated with Eremophila flowers, and Euhesma albamala in the walkeriana species group.

Re-establishment of species from synonymies based on DNA barcoding and phylogenetic analysis using Diplopterygium simulans (Gleicheniaceae) as an example

“…Thus, rechecking the revisions based on molecular biology is necessary. In recent years, many new species were identified by using the methods of molecular biology [ 16 , 18 ] and a few studies reanalyzed the synonymies. Liu et al (2013) reinstated Arthropteris guinanensis H.G.…”

“…Here, we combined these two methods to identify species. Recently, many new species have been discovered based on these methods [ 16 – 18 ], but few synonymies were re-recognized [ 19 ].…”

Twenty six new species of Leioproctus (Colletellus): Australian Neopasiphaeinae, all but one with two submarginal cells (Hymenoptera, Colletidae, Leioproctus)

“…The latter surveys are the result of a partnership between the Australian Government, BHP Billiton and Earthwatch Australia to document fauna and flora from selected national reserves. These surveys regularly result in the discovery of new invertebrate species (e.g., true bugs: Symonds and Cassis 2014; spiders: Baehr et al 2013; bees: Hogendoorn et al 2015, Leijs and Hogendoorn 2016; review of new described species: Taylor et al 2017a, b).…”

New species of Goniocolletes and Trichocolletes (Hymenoptera, Colletidae) from southern Australia

“…These surveys regularly result in the discovery of new invertebrate species (e.g. true bugs: Symonds and Cassis 2014; spiders: Baehr et al 2013, bees: Hogendoorn et al 2015). …”

“…Close to 60% of the known species are not in identification keys and with each generic revision numerous new species are added (Batley and Hogendoorn 2009). Therefore, species identification and recognition of new species is most straightforward for those genera that have recently been revised and where species identification keys have been included in the revision (Hogendoorn et al 2015). Here, we describe species in two genera of Colletidae that were revised recently ( Trichocolletes : Batley and Houston 2012; Goniocolletes : Maynard 2013).…”
