Pseudanaphothrips achaetus

Pseudanaphothrips achaetus (Bagnall) (Figs 6, 7, 10, 14, 18, 19, 27) Pseudothrips achaetus Bagnall, 1916: 398. Described originally from an unspecified number of both sexes collected from flowers on Mt Lofty, South Australia, this species has been studied from multiple sites across all Australian States and Territories. It has been found widely in New Zealand and specimens have been studied in ANIC from Hawaii, Maui, and Timor Leste. Bhatti (1978) recorded four females and one male from two separate sites near Surabaya in Java, taken in 1920 and 1925. The published record of this species from California (Mound et al. 2019) is based on nine females and one male in the collection at Riverside, California, collected from the flowers of various plant species in May 2006 at Riverside and identified by M. Hoddle and L. Mound. In structure, this is probably the most derived species within the genus, the length of the pronotal posteroangular setae being greatly reduced (Fig. 7). The fore wings are shaded but pale at the base, and the body is brown although paler in teneral adults. The metanotal median striae vary in how closely they converge at the posterior (Figs 18, 19) and the paired campaniform sensilla are sometimes absent. The posteromarginal comb on tergite VIII usually comprises a few closely spaced microtrichia medially with few laterally (Fig. 27), and the ctenidia often arise on or close to the anterior margin of each spiracle. In males, the sternal pore plates are more narrowly transverse and slender than in most members of this genus (Fig. 14).
