DESCRIPTION: Holotype female: Length:

3.1 mm; head, scutellum, metanotum, propodeum, netrion, metapleuron dark brown; anterior margin of frontal ledge, mandibles, pronotum, mesonotum, propleuron light brown; antenna, legs yellow; metasoma predominantly dark brown, lighter medially.

Head globose, length 1.5 times width; vertex rugulose punctate covered with decumbent setae; frontal ledge strongly produced with 10 longitudinal costulae, between costulae transversely subdivided by sculpture, anterior margin produced into 14 upcurved, obtuse projections, lower surface of projections smooth; upper portion of gena rugulose punctuate, otherwise largely smooth, with sparse punctures; mandible long, sigmoid, apical twothirds dentate, outer margin with five to six acute, ventrally directed teeth, inner margin with two acute teeth, apex of mandible acute.

Mesosoma height 1.4 times width; mesoscutum densely punctuate, covered with decumbent hairs; notauli abbreviated; scutellum rugulose-punctate, covered with sparse, erect hairs; dorsellum tridentate, teeth short, subequal in length, lateral teeth curved medially; forewing extending to T5.

Metasoma length 2.1 times greatest width; T1 longitudinally costate; T2 longitudinally costate medially, rugulose-punctate laterally, largely glabrous medially, setose laterally; T3– T4 medially and along anterior margin smooth, otherwise punctate with coriaceous microsculpture, finely setose; T5–T6 punctate with coriaceous microsculpture, densely setose throughout; cercus with long sensory bristles.

Male unknown.

DIAGNOSIS: Distinguished from T. genieri by the tridentate dorsellum, the punctate mesoscutum and scutellum, the short notauli, the greater number of mandibular teeth, and the greater number or projections on margin of the frontal ledge.

ETYMOLOGY: From the Latin crenatus , notched or toothed, referring to the anterior margin of the frontal ledge.
