Colletid bees, Bush Blitz survey
This paper reports on bee species that were collected on Bush Blitz surveys in remote locations of Australia. Bush Blitz is a partnership between the Australian Government, BHP Billiton and Earthwatch Australia to document fauna and flora on selected national reserves. These surveys regularly result in the discovery of new invertebrate species (e.g. true bugs:
The Australian native bee species are still relatively unknown. Close to 60% of the known species are not in identification keys and with each generic revision numerous new species are added (
Bee species were caught on flowering plants using a hand net. Specimens of Trichocolletes and Goniocolletes were identified using identification keys in recent revisions of these genera by
For descriptions of the new species the terminology used by
Some of the specimens treated here were also submitted to BOLD (Barcode of Life Database) for DNA barcoding using the cytochrome c oxidase subunit 1 gene. Specimen details, including DNA sequence, collecting dates and locality information can be accessed in BOLD under the project Australian Bee Survey, e.g. http://www.boldsystems.org/index.php/Public_RecordView?processid=AUSBS310-13
AUSBS-numbers are presented under material examined.
Under material examined, collection data are presented as copied from the specimen labels. Therefore, data formats for locality coordinates could vary. For specimens collected by Leijs et al. the locality coordinates are in decimal degrees.
Two species of Goniocolletes were collected during a Bush Blitz survey at Hiltaba Station circa 130 km East of Ceduna, South Australia, November 2012. A single specimen of G. abdominalis (SAMA32-032978 / AUSBS 313-13) was collected on the same flowering Eucalyptus as where a number of other Goniocolletes males were caught. Using the key and information provided in
As only a single species is added to this genus, we do not produce a completely new key, but suggest modifying the key produced by

January, March, November.
Eucalyptus (Myrtaceae), Melaleuca (Myrtaceae), Myoporum (Myoporaceae).
Known from seven localities in southern Australia, east and west of the Nullarbor Plain.
The species is named after Stan Wann, the grandfather of the co-collector, Beth Tully. Stan Wann grew up in the bush on the north coast of NSW, and had a profound knowledge of the birds and trees in the area.
Ten species of Trichocolletes were collected during a Bush Blitz survey at Credo Station circa 120 km NW of Kalgoorlie, Western Australia between 29 August - 9 September 2011. The majority of the Trichocolletes species were caught on Mirbelia microphylla (Fabaceae) which was profusely flowering at many sites in the reserve. The Trichocolletes species avialis, nitens and rufibasis were most common and abundant, but among these also single specimens of aureotinctus, dowerinensis, dundanensis and leucogenys were collected. A single male of T. eremophilae was caught in an area with flowering Eremophila (Myoporaceae) and Senna (Fabaceae). Additionally, a male (first recorded) and females of T. luteorufus were collected on Senna glutinosa spp. chatelainiana. Here the male of T. luteorufus is described.
As we only add the male of a single species, we do not produce a completely new key, but suggest modifying the key for the males presented by Batley and Houston (2013, pg. 5), by inserting couplets as follows:
