Pascoe

Cerambycinae

Titurius Pascoe, 1875: 63. Type species: Titurius calcaratus Pascoe, 1875.

Diagnosis

Small, slender beetles with moderately long filiform antennae. Frontoclypeus transverse. Eyes large, finely facetted and distinctly emarginate. Antennal insertions separated apically, removed from mandibular articulation by 2–3 times diameter. Antennal foramen lateral, with internal articulation. Antennal scape gradually expanded toward apex, distinctly shorter than pronotum; pedicel short and transverse; antennomere 3 shorter than scape, as long as or longer than antennomere 4; antennomeres 4–7 without spines. Pronotum transverse, lateral margins nodulose at middle; pronotal disc without tubercles. Prosternal process narrow, not expanded apically. Procoxal cavities oval with broad lateral extensions; open externally. Procoxae projecting below prosternal process. Mesoventrite flat or gradually rising anteriorly; mesoventral intercoxal process broad, notched apically. Mesocoxal cavities broadly open to mesepimeron; mesotrochantin visible. Elytra complete; elytron without costae; punctures visible, partially arranged in striae. Hind femur not exceeding apex of abdomen; hind tibia with sharp pointed apical spine.

Distribution and Biology

Distributed from Mt Walsh near Biggenden and Toowoomba in southern Queensland, to the Blue Mountains in New South Wales and to the Australian Capital Territory.

Adults are active by day and have been collected from October to January from flowering trees and bushes (Leptospermum sp., Syzygium smithii and Melaleuca ericifolia).
