Hypocisseis ornata Distinctive features
Head with frons strongly concave between heavy 'eye-brow-like' forward-projecting ridges that border the inside edge of the eyes; pronotum and elytral surface very uneven; coloration dark grey-brown with areas of blue reflections.
Despite its wide distribution spanning southern Australia and its common mistletoe hosts, this species appears not to have been collected in SA since being described by Carter 1923a around 100 years ago. Carter cited two localities: Lucindale in the SE Region of SA ,and Geraldton in WA; the former is represented in the SA Museum by five syntype specimens.
In October 2021 I found degraded dead remains of two specimens in stems of a dead mistletoe on Fleurieu Peninsula. This prompted more systematic searching, and in the same month dead remains were discovered in the SE Region by A.M.P. Stolarski and I found a live pupa in the Adelaide foothills.

Host plant notes
Strongly associated with mistletoes (Loranthaceae); Armstrong 1947 refers to adults being taken on two species of mistletoe in NSW (as 'Loranthus', probably Amyema spp. There are two more recent WA collections by R.P. McMillan in the SA Museum which show that Amyema is a larval host. A pair was cut from 'from tunnels in Loranthus preissii' (now Amyema preissii) and a single individual was 'cut from Amyema'. The mistletoe A. preissii also occurs widely in SA and mainly parasitises Acacia species. The recent SA larval host records are from A. miquelii (Box Mistletoe), another common species that parasitizes a range of woodland Eucalypts in temperate areas, and, occasionally, a small number of mallee Eucalypt species.
