03F55278FFA3FFB9F3297E1BFBF6F9FE.taxon	distribution	Distribution and biology The species is currently recorded from a single locality, Croydon in the Gulf of Carpentaria area of Queensland, in the Gulf Plains bioregion (Fig. 7). The specimens were collected in March. They are cryptic when sitting on the branches of their host plant, Acacia holosericea A. Cunn. ex G. Don / A. colei Maslin & L. A. J. Thomson (Fabaceae) in open Eucalyptus L’Her. woodland (Figs 5 – 6). A specimen was observed at day time, in a trophobiotic interaction with ants collecting the honeydew produced by the planthopper. The ants were identified as Camponotus wiederkehri Forel, 1894 (Hymenoptera: Formicidae: Formicinae) (Fig. 5 C – F) and the observed ant specimens belong to different casts; the behaviour of the ants included antennal, palpal and proleg contact / palpation which are regarded as a way to stimulate honeydew production by the planthopper (Bourgoin et al. 2023).	en	Constant, Jérôme (2026): Revision of the Eurybrachidae IXX.
