Description

Female

Unknown.

Male

BODY LENGTH. 19 mm.

HEAD. Transversely subrectangular with posterolateral angles rounded in dorsal view; lateral margins of head convergent immediately behind eyes. Vertex width 0.8× pronotal width. Eye almost circular. Ocelli small; OOD 3.4× DLO, IOD 0.8× DLO. Occipital carina distinct. Head surface sparsely and finely punctate; sculpture sparser and finer posterad. Gena ecarinate. Antennal scrobe concave to eye margin, with well-defined transverse dorsal scrobal carina. Clypeus concave laterally immediately below antennal insertion, conspicuously convex medially; densely and coarsely foveolate-punctate, coarser mediad; apical/ventral margin with a pair of medial short subacute free teeth medially. Scape bicarinate. Flagellomere 1 2.0 × pedicel length; flagellomere 2 2.6× pedicel length. Mandible obliquely tridentate apically, medial tooth smaller than inner tooth; lacking dorsal or ventral projections.

MESOSOMA. Epaulets well defined, sharply projected from anterior margin of pronotum, separated from well-defined humeral carina, anterolateral corners of pronotum subangulate.Anterior surface of pronotum, with coarse dense punctures laterally, micropunctures sublaterally, and medial longitudinal, slightly concave, smooth, unsculptured area. Tegula convex, mostly glabrous and impunctate except for dense coarse punctures along inner and anterior margin. Dorsum of pronotum densely and coarsely foveolate-punctate mediad to areolate-punctate laterad with somewhat sharp intervals. Mesoscutum densely and finely foveolate-punctate, parapsis and notaulus reduced to posterior half of mesoscutum. Scutellum ‘box-like’, with conspicuously horizontal dorsal surface roundly angulate into nearly vertical posterior surface; dorsal surface shorter than posterior surface; sculpture densely and coarsely areolate-punctate to foveolate-punctate. Axilla produced posterolaterally as obliquely truncate projection in dorsal view; projection coarsely foveolate-punctate basad, unsculptured, smooth, shining apicad. Metanotum slightly wider laterad, its surface obscured by dense setation. Propodeal dorsum convex, slightly depressed sublaterally, mostly concealed by dense setation, densely areolate where visible; sculpture of lateral surface absent along most of anterior margin; dorsal surface indistinguishable from posterior surface. Lateral surface of pronotum sparsely and vestigially punctate with sparse interspersed micropunctures; mesopleura with conspicuous blunt projection on dorsal half; sculpture densely and coarsely areolate with interspersed micropunctures to simply micropunctate anterad. Metapleuron micropunctate, except basal third densely and coarsely areolate.

WINGS. Forewing with elongate sclerotized pterostigma; marginal cell elongated, roundly truncate apically; three submarginal cells.

LEGS. Simply setose, no strong spines discernible dorsally; spurs finely serrate on margins.

METASOMA. T1 0.5× as wide as T2. T2 0.9× as long as wide. Dorsal metasomal sculpture, except pygidial plate, partially concealed by dense setation, sparsely and finely punctate with sparse interspersed micropunctures where visible; sculpture sparser and less defined in apical segments; pygidial plate slightly broader than long, weakly defined by parallel carinae laterally; surface densely micropunctate throughout. S1 longitudinally elevated medially, terminating in slightly concave low longitudinal carina, carina slightly higher posteriorly. S2 sparsely and finely foveolate-punctate to punctate with few scattered micropunctures laterally; sculpture sparser mediad; anteromedial crest-fold present, sternal pit absent. S3–7 sparsely and finely foveolate-punctate to punctate; S7 longer than broad, posterior margin projected medially into closely bidentate apex.

GENITALIA. Parapenial lobe not at all pronounced posteriorly, subacute. Ratios of free length of paramere, cuspis and digitus, 77: 52: 18. Paramere almost straight in dorsal view, apex slightly curved outward, slighlty narrower posterad, upcurved posteriorly in lateral view, almost asetose except for sparse scattered inconspicous setae throughout, setae more evident on ventral surface. Cuspis slender, elongate, slightly curved inward and tapered posterad in dorsal view, upcurved posterad and almost straight throughout in lateral view, with tuft of conspicuous long setae at apex and sparser scattered inconspicuous short setae elsewhere. Paracuspis poorly developed, sessile, lobe-like, wider than long with rounded and setose posterior margin, setae shorter than or longer than paracuspis. Digitus short, slightly curved inward in dorsal view, strongly tapered posterad and with apex abruptly curved dorsally in lateral view, setose anterodorsally. Penis valve strongly concave on inner surface, with well-defined pair of short acute teeth posteroventrally, with well-defined lateral pocket on outer margin, apical distance between teeth 0.1× length of valve, dense setae present along truncate posterior margin and inconspicuous setae present at base of anterior tooth on outer surface.

Coloration and variations

Integument black. Body setae predominantly black varying in density, except the following areas with silvery-white setae varying in density: anterior/ventral margin of clypeus; metanotum, prodeal dorsum; legs predominantly (occasionally all black); T1, anterior third, lateral areas, lateral felt lines, and lateral margins of T2; fringe of T2 laterally, fringe of T3 medially and laterally, fringe of T4–5 laterally, and S1–4. Wings dark brown throughout with strong violaceous and blueish reflections.

Distribution

Brazil (Rondônia, Bahia, Mato Grosso, and Minas Gerais), Paraguay (Amambay and Concepción) and Bolivia (Santa Cruz and Beni).

Remarks

This species can only be separated from T. infernalis on certain genitalia and setae pattern characters. Likewise, it can be a candidate for a sex association with T. sancta based on its known distribution (also see remarks of T. infernalis ).
