The sole specimen described here was collected from a fossil locality near Daohugou Village, Inner Mongolia, China, from which plants, diverse insects, conchostracans, anostracans, spiders, salamanders, pterosaurs, and mammals have also been discovered (Huang et al., 2006). The specimen is housed in the Nanjing Institute of Geology and Palaeontology, CAS, Nanjing, China. The specimen was observed and photographed using a Zeiss Discovery V20 stereo microscope. It was examined both dry (under low-angled light) and under 70% alcohol.
