Distribution. South-eastern Queensland to the northern tablelands of New South Wales ( Figure 61 ).

Diagnosis. Male: hypopygium with apical spine large and broadly triangular and the lateral spines relatively small (see Brown 1995b: Figure 5 ). Aedeagus long and narrow with the apex narrowed and slightly down-turned, and the dorsal margin of the ventral lobe curved (see Brown 1995b: Figure 15 ). Gena short and approximately quarter length of minimum eye diameter (see Brown 1995b: Figure 7 ; 2001: Figure 14 ).

Female: frons and vertex with a semicircular area of finer punctures interspersed between deeper punctures. Pygidium strongly narrowed dorsally with two medial longitudinal carinae (see Brown 2001: Figure 19 ).

Description. Female: brown; antennae and legs slightly paler. Head subrectangular, slightly wider than long, posterior angles rounded, eyes relatively large, not strongly protuberant, almost reaching base of mandibles. Mandibles long, evenly curved, without preapical tooth. Clypeus narrowly truncate apically, closely and finely punctate, sharply medially carinate basally to near apical margin. Frons obscurely sagittally sulcate. Frons and vertex deeply rugosely punctate interspersed with small shallow punctures in a large semicircular area bounded by the inner orbits of the eyes and most of the vertex (except laterally and posteriorly). Pronotum trapezoid with lateral margins converging posteriorly, dorsal and lateral surfaces clearly delineated from dorsum, margins not carinate, dorsum rugosely punctate, punctures aligned longitudinally, lateral surface longitudinally multistriate with striae subparallel to ventral margin becoming rugosely punctate dorsally. Mesoscutellum trapezoid, closely punctate. Propodeum closely to rugosely punctate dorsally, rugosely punctate posteriorly, longitudinally striate laterally. Mesopleura with small dorsal surface below level of mesoscutellum, produced anterolaterally into a vertical carina. Metasoma rugosely punctate, punctures longitudinally aligned, T 1–5 with posterior line of longitudinal punctures blending in with other punctation; T 6 almost smooth medially, longitudinally, striations short, confluent and appearing as two parallel lines medially, with lateral fringe of setae, lateral margins strongly convergent dorsally, apical margin not broadly rounded, narrowly emarginate; T 1 with vertical declivity anteriorly; S1 short, broad, medially raised, not carinate; S6 with weakly raised lip on posterior margin. BL: 8.

Remarks. This is the most southern species, and is the only species found outside tropical Australasia.

The female has not been described previously, and apart from T. subtriangularus , is the only known female for this genus.
