Las 4.4 imaging system

Specimens were point mounted on black, acid-free card for examination (using a Leica M205C stereomicroscope with LED light source), photography and long term preservation. Images were acquired using the Leica LAS 4.4 imaging system, which comprised a Leica® Z16 microscope with a Leica DFC450 Camera with 0.63× video objective attached. The imaging process, using an automated Z-stepper, was managed using the Leica Application Suite V 4.4 software installed on a desktop computer. Lighting was achieved using techniques summarized in Buffington et al. (2005) , Kerr et al. (2008) and Buffington and Gates (2009) .

At SAMC we used a Leica LAS 4.4 imaging system, which comprised a Leica® Z16 microscope with a Leica DFC450 Camera with 0.63× video objective attached. The PageBreakimaging process, using an automated Z-stepper, was managed using the Leica Application Suite V 4.4 software installed on a desktop computer. At BMNH, images were acquired using a Canon SLR EOS 5DSR with 65 mm macro lens mounted on a copy stand with an automated Z-stepper; images were aligned using Helicon Focus software version 6.6.1. Diffused lighting was achieved using techniques summarized in Buffington et al. (2005) , Kerr et al. (2008) , and Buffington and Gates (2009) .
