DESCRIPTION: Holotype female: Length: 4.2 mm; head, metasoma dark brown to black; anterior margin of frontal ledge, mandibles, A8–A11 brown; mesosoma light brown; legs, A1–A7 pale yellow.

Head large, elongate, length 1.6 times width; vertex rugulose punctate, sculpture with strong longitudinal orientation, covered with numerous semidecumbent setae, medially with longitudinal furrow extending from occipital carina to median ocellus; frontal ledge strongly produced, with 11 longitudinal costulae, between costulae with line of setigerous punctures, anterior margin of ledge produced into 10 upcurved, truncate projections, lower surface of projections smooth, setose; upper portion of gena longitudunally rugulose, otherwise largely smooth, with sparse setose punctures near eye; mandible long, sigmoid, apical half dentate, outer margin with three acute, ventrally directed teeth, inner margin with two acute teeth, long truncate basal tooth, apex of mandible spatulate.

Mesosoma height 1.5 times width; mesoscutum finely, longitudinally costulate, covered with fine dark setae; notauli present, fine, nearly percurrent; scutellum longitudinally costulate, covered with fine dark setae; dorsellum in form of semicircular lamella, without armature; forewing extending to apex of T4.

Metasoma length 2.0 times greatest width; T1 longitudinally costate, with simple line of setae along lateral margin; T2 longitudinally costulate, largely glabrous medially, finely setose laterally; T3 longitudinally costulate with superimposed coriaceous microsculpture, setose throughout; T4–T6 shallowly punctate with coriaceous microsculpture, densely setose throughout; sensory bristles arising from cercus short.

Male: Nearly identical to female; somewhat smaller, length 3.5–4.0 mm; A1–A2 pale yellow, A3–A12 dark brown; A3 much longer than A2; flagellomeres elongate, with erect setae, each flagellomere distinctly separated; mandible narrower; forewing extending posteriorly to apex of metasoma.

DIAGNOSIS: Distinguished from T. crenatus by the semicircular dorsellum, the longitudinally costate mesoscutum and scutellum, the elongate notauli, the smaller number of mandibular teeth, and the smaller number of projections on the frontal ledge.

ETYMOLOGY: Named in honor of one of the earliest collectors of the type series, François Génier (Canadian Museum of Nature, Ottawa).
