Described in a key, this species is known only from a single male, collected at Cedar Creek in northern Queensland between 1910 and 1913. A second specimen, taken at Colosseum, is a female not a male (see Karny, 1924: 22), and is here considered to be a different species because it has much shorter major setae and more extensive yellow on the hind tibiae. The holotype has long pale major setae; the postocular setae are longer than those of the acripilus holotype but the pronotal posteroangular and epimeral setae are shorter. The maxillary stylets are long and particularly close together medially ( Fig. 19 ), but although the mouth cone is long and pointed it does not reach to the mesopraesternum, possibly because the pronotum of this male is so massive. The fore femora are enlarged, and the fore tarsal tooth is also large. The metanotal reticulation is arranged concentrically ( Fig. 18 ), the three sub-basal setae on the forewing are arranged in a straight line, but only four duplicated cilia are visible. Antennal segments IV and V are yellow with only weak brown shading at the apex. There is a large glandular area occupying the eighth sternite except for the posterior margin. Several specimens closely similar to this holotype were beaten from Geijera parviflora at Dalby, South East Queensland. However, these have the antennal segments, including segment III, more extensively brown, the pronotal anteromarginal setae scarcely longer than the width of the second antennal segment, the apices of the major setae only weakly expanded, and the forewing sub-basal setal bases arranged in a triangle, as in T. ater .
