Mound, Laurence A., Dang, Li-Hong & Tree, Desley J., 2013, Genera of fungivorous Phlaeothripinae (Thysanoptera) from dead branches and leaf-litter in Australia, Zootaxa 3681 (3), pp. 201-224 : 207

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. 9 ). However, Mound (1972a) 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.
