Nesothrips badius (Hood, 1918: 143) comb.n.

(Figs 48, 56, 59)

Described in Cryptothrips, this species was transferred to Bolothrips by Mound (1974 a) because of the long head and small eyes (Fig. 48), as well as its habitat at the base of grasses and sedges. Subsequently it was re-assigned to Carientothrips because of the presence of four sensoria on the fourth antennal segment (Mound 1974b). However, it is here transferred to Nesothrips because of the arrangement of the maxillary stylets, wide apart and V-shaped in the head (Fig. 48), and because of the form of the maxillary palps, with the first segment short and quadrate and the second segment three times as long as the first (Fig. 56). This species is widespread in eastern Australia from northern Queensland to Tasmania, and is also common in New Zealand (Mound & Walker 1986). The most closely related species is barrowi sp.n. that is known only from a single specimen taken on Barrow Island, off the northwestern coast of Western Australia.

Diagnosis. Usually effectively apterous with the wing lobe less than 40 microns long and the ocelli absent; body, legs and antennae dark brown with segment III briefly paler at base (Fig. 59); head elongate, cheeks sinuate, constricted behind eyes but broader medially, maxillary stylets wide V-shaped, not retracted as far as postocular setae; eyes small, postocellar and postocular setae small and acute; pronotum am setae small, remaining major setae not large; mesopresternum boat-shaped, metathoracic sternopleural sutures not present; metanotum weakly sculptured; pelta very broadly triangular with rounded corners; tergites with about 10 discal setae in median transverse row, median pair longer than lateral setae, wing-retaining setae long and straight; tergite IX setae acute, about as long as tube. Male smaller than female, with fore tarsal tooth; pronotum of large male with thickened median apodeme.
