Specimens are pinned and deposited in the Western Australian Museum, Perth (WAM), and the M.L. Moir personal collection, Perth (MLM). Specimens were examined with an Olympus SZ51 stereo microscope, and all images were produced using a Leica MZ16 stereo microscope and the package Auto- montage Pro version 5.02(p) (Syncroscopy, Cambridge, U.K.). A map of species distribution was produced in ArcGIS Version 9.1 (Environmental Systems Research Inc.). Tingidae terminology follows Froeschner (1996) and Lis (2000), classification follows Guilbert (2012).

ABSTRACT – This paper describes three new species of Ceratocader (Tingidae), almost doubling the number of known species. Ceratocader langlandsi sp. nov. is found in arid south Western Australia. In contrast, C. coatesi sp. nov. and C. bridgettae sp. nov. are found in the wetter tall forests of the far south-west of Western Australia. Notes on the genus, and its sister genus, Australocader, as well as a key to species of Ceratocader, are provided. INTRODUCTION The endemic Australian lacebug genus Ceratocader Drake, 1950 (Hemiptera: Heteroptera: Tingidae) is currently represented by four described species. Ceratocader armatus (Hacker, 1928), the armed lacebug, is recorded from South Australia, and C. dentatus (Hacker, 1928), the dented lacebug, from northern Tasmania (Hacker 1928; Cassis and Gross 1995). Lis (2000) added a further two species: C. fulvus Lis, 2000 from the far south-west of Western Australia and C. monteithi Lis, 2000 (Monteith’s lacebug) from central Queensland (Figure 1). Western Australia is particularly rich in lacebug species of the family Tingidae, with a key to the genera present in the south-west provided by Moir and Guilbert (2012). Despite recent publications documenting new species (e.g. Cassis and Symonds 2008, 2011; Guilbert and Moir 2010; Moir 2009; Moir and Guilbert 2012) many species await description. Here, we describe three new species of Ceratocader from Western Australia: Ceratocader langlandsi sp. nov. from the arid southern region, plus C. coatesi sp. nov. and C. bridgettae sp. nov. from the far south-west of the State (Figure 1). In addition, a discussion on the genus and a key to species is provided. MATERIALS AND METHODS The specimens examined here were collected by beating, vacuum sampling or pitfall traps (see Langlands et al. 2006; Moir et al. 2005a; Orabi et al. urn:lsid:zoobank.org:pub:14E1F58D-47BE-4839-85EC-8CEEF76FBAC8
