Female. Body length 12 – 17 mm. Head. Posterior margin virtually straight. Occipital carina slightly swollen and smoothly curved dorsolaterally. Vertex width 0.55 × pronotal width. Eye almost circular, its length in frontal view 0.8 × to the distance from its ventral margin to mandibular condyle. Head sculpture concealed by dense setation, except gena and malar space densely and coarsely foveolate-punctate. Mandible with small subapical tooth. Dorsal scrobal carina present, well-defined, reaching but not extending over antennal tubercles; lateral scrobal carina virtually absent. Antennal tubercles virtually unsculptured, smooth and shinning. Flagellomere 1 2.4 × pedicel length; flagellomere 2 1.8 × pedicel length. Mesosoma. Dorsal thoracic length 0.8 × its width. Mesosomal dorsum well differentiated from pleurae, lateral margins rounded, not sharp or angulate; sculpture predominantly obscured by dense setation, dense and coarse areolate-punctate where visible, denser and smaller mediad; intervals vestigially scabrous. Anterior face of propodeum well-defined, coarsely striated longitudinally medially, sparsely punctate laterally; dorsal face roundly angulate into anterior face in lateral view. Humeral carina present, broadly separated from well-defined, slightly projected, rounded epaulette; anterolateral corners of pronotum rounded in dorsal view. Pronotal spiracle projected from lateral margin of pronotum, rounded. Sculpture of lateral face of pronotum sparsely punctate with dense micropunctures; mesopleuron densely micropunctate anteriorly, dense coarse and confused foveolate-punctate along mesopleural ridge, concealed by dense setation elsewhere; metapleuron sculpture predominantly concealed by dense setation, except dorsal fourth unsculptured and asetose, smooth. Lateral face of propodeum densely and coarsely foveolate punctate with interspersed micropunctures on posteroventral half. Ratios of width of humeral angles, pronotal spiracles, widest point of mesonotum, narrowest point of mesonotum and propodeum posterior to propodeal spiracles, 52:67:65:55:53. Lateral margin of mesonotum slightly emarginated anterior to propodeal spiracle, smoothly diverging anterad. Propodeal spiracle strongly projected from lateral margin of mesosoma; post-spiracular area absent. Scutellar scale present, well-developed, slightly narrower than and separated from well developed anterolateral carinae which are connected thus forming a single transverse carina with shallow emargination medially; scabrous intervals present on scutellar area. Posterior face of propodeum slightly longer than and poorly distinguished from dorsal face. Metasoma. Ratios of width of T1, width of T2 and length of T2, 38:88:86. Disc of T2 densely and coarsely foveolate-punctate to punctate, sculpture denser and smaller mediad, sparser and shallower over integumental spots. T3 – 6, except pygidial plate, predominantly concealed by dense setation, densely and coarsely foveolate-punctate where visible. S1 sparsely punctured, surface cuneiform, ending in a rounded longitudinal carina, equally high throughout. S2 densely and coarsely foveolate-punctate, more sparserly so posteromedially; anteromedial crest-fold vestigial. S3 – 6 densely and coarsely foveolate-punctate. Pygidial plate broadly subovate, defined by lateral carinae at apical half of plate; surface mostly irregularly longitudinally rugose, rugae vestigial laterally.

Male. Body length 15 mm. Head. Rounded subrectangular in dorsal view, posterolateral angles rounded. Vertex width 0.75 × pronotal width. Eye almost circular. Ocelli small; OOD 3.5 × DLO, IOD virtually equal to DLO. Occipital carina distinct. Head surface densely and coarsely foveolate-punctate to punctate. Gena ecarinate. Antennal scrobe concave to eye margin, with prominent transverse dorsal scrobal carina narrowly separated from internal eye margin. Clypeus slightly concave laterally immediately below antennal insertion, convex medially; coarsely and densely foveolate-punctate to punctate; with a pair of short, sessile, blunt tubercles on apical margin. Scape bicarinate. Flagellomere 1.75 × pedicel length; flagellomere 2.1 × pedicel length. Mandible obliquely tridentate apically, inner tooth slightly larger than middle tooth; lacking dorsal or ventral projections. Mesosoma. Epaulettes well defined, slightly projected from anterior margin of pronotum, rounded, broadly separated from humeral carina, anterolateral angles of pronotum subangulate. Anterior face of propodeum coarsely foveolate-punctate to punctate laterally, unsculptured medially, with a conspicuous longitudinal slightly concave medial area. Tegula convex, mostly glabrous and impunctate except for dense coarse punctures anteriorly and along inner margin. Mesoscutum densely and coarsely foveolatepunctate, notaulus and parapsis indistinguishable. Scutellum convex, densely and coarsely foveolate-punctate. Axilla produced posterolaterally as truncate projection, with conspicuous flat posterior face, coarsely and densely foveolate-punctate dorsally; posterior face of axillar projection arched. Metanotum slightly wider laterally, its surface obscured by dense setation. Propodeum dorsum convex, partially concealed by dense setation, densely areolate where visible; lateral face predominantly densely areolate, areolations less defined anterad; posterolateral margins rounded, posterodorsal corners rounded in lateral view; dorsal and posterior faces indistinguishable. Lateral face of pronotum densely coarsely and confusedly foveolate-punctate to punctate with interspersed micropunctures; mesopleura with strong blunt tubercle on dorsal half; mesopleural sculpture densely and coarsely areolate-punctate to foveolate-punctate with interspersed micropunctures anteriorly. Metapleuron sculpture concealed by dense setation. Wings. Forewing with elongate sclerotised pterostigma; marginal cell elongated, 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 length 0.9 × its width. Dorsal metasomal sculpture partially concealed by dense setation, densely and coarsely foveolate-punctate to simply punctate where visible, except pygidial plate on T7 irregularly rugose and weakly defined by parallel carinae apicolaterally, rugosities predominantly transverse. S1 longitudinally elevated medially, forming pronounced carina slightly higher posteriorly. S2 foveolate-punctate, foveolations conspicuously sparser and smaller mediad; with well-developed longitudinal anteromedial crest-fold ending on elongate and narrow longitudinal pit densely filled with setae. S3 – 7 sparsely foveolatepunctate to punctate. S7 slightly broader than long, with a pair of subacute closely spaced tooth-like projections on posterior margin. Genitalia. Parapenial lobe slightly pronounced apically. Ratios of free length of paramere, cuspis and digitus, 64:55:7; paramere slightly sinuous in dorsal view, upcurved apically in lateral view; with dense long setae ventrally except at apically with setae conspicuously reduced; cuspis narrow, slender, in dorsal view slightly curved inward at basal half and curved outward in apical half; conspicuously and smoothly widened apically; predominantly asetose with sparse conspicuous setae ventrally at apex; paracuspis well-developed, not sessile, twice as long as wide, roundly subtriangular at apical margin, densely setose, setae predominantly shorter than paracuspis; digitus short, curved inward in dorsal view and upcurved in lateral view, setose dorsally; penis valve strongly concave on internal surface, with very closely spaced pair of teeth apicoventrally; apical tooth more acute and longer; subapical tooth acute, externolateral vestigial; apical distance between teeth 0.03 × length of valve; dense setae present along apical margin and at base of teeth on external surface.

Colouration and variations

Female. Integument predominantly black to reddish-black except mandibles basally and most flagellomeres ventrally reddish-brown. Setae predominantly silvery-white to silverygolden varying in density except the following areas with black setae varying in density: gena, malar space, posterior margin of vertex, ventral surface of head, pronotum, mesonotal dorsum, propodeal dorsum medially, T1 – 2 medially, fringe of T2 medially, and fringe of T3 – 5 sublaterally; no conspicuous colour or setae variations were observed in the specimens examined.

Male. Integument entirely black except most flagellomeres reddish-brown ventrally. Setae predominantly silvery-white varying in density except the following areas with black setae varying in density: head predominantly, pronotum, mesopleuron above tubercle, mesonotum, axillae, scutellum, T2 posteromedially, fringe of T2 – 5 medially and T6 – 7; no conspicuous colour or setae variations were observed in the specimens examined.

Remarks

Mickel identified numerous specimens of this species in different collections as ‘ T. speciosa   sp. n. ’ and even labelled certain specimens as paratypes. No mention of the name, however, was ever made in published literature. Males herein associated with T. guarata   , though almost structurally identical to the other males of the T. juvenilis   species group, can be reliably associated with the females based on distribution and their distinct setal pattern, which can be observed in both sexes of species typical of the Atlantic Forest, such as Hoplocrates cephalotes (Swederus)   , Hoplomutilla spinosa (Swederus)   , Pappognatha patruelis (André)   , and Ephuta chrysodora (Perty)   (KAW, pers. obs.).
