Biconothrips Stannard


Biconothrips Stannard 

This Urothripine genus is closely related to Urothrips  from Africa, but the only described species, B. reedi  , is known only from various sites in eastern Australia ( Fig. 9View FIGURES 8 – 18). However, Mound (1972 a) indicated that there is considerable variation between populations, and this may reflect a series of localised species.

Diagnosis. Apterous, body tuberculate-reticulate; head anterior margin projecting over bases of antennae, without prominent setae; eyes with about 8 ommatidia; stylets retracted almost to eyes, about 1 / 3 of head width apart; antennae 5 -segmented, morphological segments III –V fused, VII –VIII fused to form slender segment; pronotum without prominent setae, or with epimeral setae well-developed, notopleural sutures reduced; basantra absent; mesopraesternum absent or very slender; no sternopleural sutures; fore tarsi without tooth; pelta transverse, closely joined to tergite II; tergite IX twice as long as VIII; tube about as long as IX, anal setae more than three times as long as tube; male sternite VIII without pore plate.
