Apelaunothrips medioflavus (Karny)

( Figs 6 , 22 )

The third antennal segment of this species is reported to have only two sensoria on the third antennal segment (Okajima 1979), but one female specimen listed below from Taiwan has a third slender sensorium ventrally on the right antenna, although the left antenna has only two sensoria on this segment. The male collected with this female also has only two sensoria on the third segment. In contrast, the single female listed below from Timor has a third slender ventral sensorium on the third segment of both antennae, and this is here interpreted as intraspecific variation. The head of medioflavus is elongate, and weakly reticulate medially, but the stylets are usually close together medially, in contrast to the illustrated individual from East Timor ( Fig. 6 ). Antennal segment VIII has a distinct basal neck ( Fig. 22 ). The specimen from Timor has a pair of campaniform sensilla on the pelta, but this is absent in the specimens from Taiwan.

Specimens studied. Taiwan, Pingdong County, Nanjenshan, 1 female, 1 male from dead leaves, 3.xi.2001, in the National Zoological Museum of China, Beijing. East Timor, Ainaro, 1 female from grass, 5.xii.2003 (A. Roach), in Australian National Insect Collection, Canberra.
