| Species: | Eucalypt Longhorn (Phoracantha semipunctata)| This Photo: | Shell | Thank you Mark Hura for confirming the id of this species for us General Species Information: Found in the Adelaide Hills and possibly elsewhere Unfortunately we only found a dead shell. Note the four trailing spines on the elytra (2 per elytron). There are at least a couple of other similar species in SA; P. punctata & P. tricuspis which are hard to separate. To separate these two Samuel Westbrook, refering to P. tricuspis, said "The diverging yellowish-orange zigzag fasciae on each elytron are the biggest indicator of this species.. The costae are also more prominent and highlighted here, which is an indication of P. tricuspis. However, elytral patterns are very varied, and while helpful, other morphological characteristics should be used to corroborate. In the case of P. tricuspis/punctata this is the spines on the antenna segments. P. tricuspis is bispinose, with the males having an inner and outer apical spine on the third segments; the females are easier to ID, with segments 3-8 being bispinose. While P. punctata is unispinose. The species have different host preferences. P. tricuspis is less common than P. punctata and is underrepresented in rural areas where there are fewer people making observations. Other records of this species have it relatively evenly distributed across south-east Australia."
