| Species: | Feather-horned Longhorn Beetle (Piesarthrius laminosus)| This Photo: | S1, Male, dorsal | Other names: | Longicorn Beetle, Long-horn Beetle or Long Horned Beetle | Thank you Francesco Vitali for confirming the id of this species for us General Species Information: Found on Ellura (in the Murray Mallee, SA) and elsewhere ~15mm long with very long thin wide filaments on the antennae on the male. Females don't have the "feather"/long & wide filaments. These antennae with long, wide filaments are described as "lamellate-pectinate" or "flabellate" (meaning fan-shaped). It's difficult to determine how long the antennae are. Superficially they are a bit over 12mm long. However, the end segment has 2 filaments, of ~5mm long. So really the antennae are ~7mm, with 5mm of filament nearly doubling their length. The filaments vary in length, with the middle being the longest at ~7mm, and both edges being ~5mm. As with many longhorns, the eyes are heavily indented and wrap around the antennae base.
