Description. (Figs. 2–5)
Female: total length 27.3 mm, length of head 5.2 mm, length of pronotum 4.5 mm, length of scutellum 2.6 mm, width of head at level of eyes 2.4 mm, width of pronotum 6.3 mm, width of abdomen 9.7 mm.
Overall color black. Clavus and corium orange, except veins and internal base of corium. Dorsal connexivum totally orange.
Head black. 2.2 times longer than wide. Integument covered with short and sparse pilosity, providing almost glabrous aspect, similar to male, without rugosity, but delicately granular. Anteocular region 5 times longer than postocular, latter with sides almost straight and soft convex to back. Ocelli easily visible. Clypeus wider at posterior third. Genae rugose, surpassing apex of clypeus. Juga rugose, pointed apically. Eyes not attaining superior bor- der of head, surpassing inferior border of head. Dorsally, synthlipsis 1.3 times longer than wide (Fig. 2).
Antenniferous tubercles located at submedian part of anteocular region. First antennal segment not attaining clypeal border, with moderate pilosity consisting of short and robust hairs. Second segment with abundant short pilosity. Third segment with golden micropilosity. Ratio of antennal segments 1:5, 0:3, 2:?
Rostrum black, in lateral view, first segment not attaining base of antenniferous tubercles; second attaining posterior border of eye; third, dark brown colored, with low and tenuous pilosity, mainly at the apex. Ratio of rostrum segments 1:2.5:1 (Fig. 2).
Neck with 1 + 1 lateral orange spots.
Pronotum entirely black, and shining tenuous rugose and granulose. Color black, well marked, with anterolateral angles divergent, rounded and somewhat pointed. Interlobular sulcus with notable depression at base, extending to apical border of posterior lobe. Submedian carinae divergent, originating on posterior third of anterior lobes and attaining anterior three-quarters of posterior lobe. Humeral angles rounded, well marked and elevated (Fig. 3). 1 + 1 small brown spots at external margin of humeral angles.
Scutellum with cordate area, totally black with 1 + 1 tubercles on base that do not reach posterior border of pronotum. Central depression large and rugose, formed by large transverse striae, attaining to the base of posterior process. Posterior process short striated and subcylindrical (Fig. 4). Stridulatory sulcus with fine striae.
Hemelytra not attaining posterior border of abdomen (Fig. 5). Corium and clavus orange with black veins and lighter regions between veins. Membrane dark-yellowish fumose; veins dark brown.
Legs entirely black. Anterior and median femora with rudimentary subapical tubercles. Posterior femurs without tubercles. Ratio of width and length of anterior femur 1:8.1.
Abdomen black and shining. Sparse and short hairs. Connexivum, in ventral view, delicately striated, ventrally and dorsally orange, with brown marked areas at center of each segment, but not forming a true macula. Intersegmental sutures yellow. Tracheal spiracles yellow.
Geographic distribution and habitat (Fig. 6). We recorded the occurrence of T. baratai in six municipalities (Fig. 6), extending its geographical distribution in the state of Mato Grosso do Sul, Brazil. To our knowledge, these specimens were collected for the first time in domiciles and in peridomestic environments of rural and urban areas, highlighting the synanthropic behavior of T. baratai.
