Legs with basal lobe of all claws large and rounded; mid tibia with 3 apical and 7 preapical spines; preapical spines placed at intervals on the anterior surface in distal half of tibia; hind tibia with 5 apical and 15 preapical spines; preapical spines arranged in five rows beginning just basal to apical spines and extending along distal quarter of tibia; hind tibia in lateral view broader in apical one-third than basal one-third so tibia appears clavate.

Fore and hind wings clear; fore wing maximum width 1.2 (1.0–1.3) mm, length 3.6 (2.6–4.0) mm; cell 1-Rs absent; most of M+Cu unpigmented; hind wing maximum width 0.7 (0.5–0.7) mm, length 3.4 (2.3–3.4) mm.

Metasomal length 1.9 (1.4–2.9) mm, maximum width 0.9 (0.6–1.0) mm; median T1 surface sculpturing faintly granulate; T 1 in dorsal view quadrate in shape, length 0.5 (0.4–0.8) mm, anterior width 0.3 mm, posterior width 0.5 mm; T2+3 surface smooth as is dorsal surface of remaining metasomal tergites (anterior region T2 sometimes faintly granulate), T2 medial transverse groove a faint curved depression; T2–T3 boundary a faint depression.

Male. Same as female except for genitalia.

Comments. Camptothlipsis oliveri is distinguished from the five other undescribed Australian Camptothlipsis species examined by the pronounced scutellar sulcus with eight pits and the long and distinctly scrobiculate sternalus. The species has been collected from the Timorian, Torresian and northern Kosciuskan biogeographic regions ( Fig. 18A ) and was reared from an unidentified tortricid host feeding on the exotic plant spinyhead sida, Sida acuta Burm. f., in the Timorian region. This species is named after the senior author’s son Mr Oliver Finn Stevens.

Diagnosis. Fore wing cell 1-Rs absent; labial palpomere 3 not significantly reduced, at least 0.5x length of labial palpomere 4; notauli distinctly scrobiculate; scutellar sulcus scrobiculate with 8 pits; sternalus distinctly scrobiculate and relatively long; propodeum extensively rugose-granulate, with distinct granulate sculpturing on T1 only, although faint granulate sculpturing sometimes on anterior T2. Body mostly yellow with varying amounts of brown on dorso-posterior metasoma.
