Ansa Walker, 1868: 548 . (syn. by STÅL 1872).

Type species. Atelocerus hypomelas Burmeister, 1835, by monotypy.

Diagnosis. Mandibular plates and clypeus subequal in length. Antennomere 2 shorter than first. Labium long, surpassing the middle of sternite 5. Ostioles elliptical. Conjunctiva with one pair of processes and two pairs of lobes: median and ventral lobes. Annular flanges conver-gent.

Redescription. Body elongate (Figs. 8 A– B, 9A– B, 12A– B). Head: Head longer than wide, apex rounded (Figs. 8A, 9A, 12A, D). Mandibular plates as long as clypeus, apices obtuse; lateral margins sinuous. Clypeal apex obtuse, in a higher level than mandibular plates in lateral view; clypeal suture beginning after an imaginary line crossing anterior margin of compound eyes. Anten-niferous tubercles visible in dorsal view, each with an ob-tuse process laterally. Antennomere 1 not reaching apex of head; antennomere 2 shorter than 1, visible (Figs. 8D, 9 A– B, 12D); antennomere 3 cylindrical, slightly flat-tened; antennomere 4 cylindrical, convex dorsally (Fig. 18 Fiii). Bucculae tapering towards the base of head, not reaching its base. Labium long labium, surpassing mid-dle of sternite 5 (Figs. 9C, 12C); labiomere 1 lying en-tirely between bucculae, labiomere 2 flattened laterally, shorter than labiomeres 3 and 4 combined and labiomeres 3 and 4 uniformly entire. Thorax: Pronotum trapezoidal (Figs. 8A, 9A, 12A, D, 21 A– B); anterolateral margins explanate, not reflexed and impunctate; posterior margin slightly convex. Mesosternal carina elevated, smooth; metasternal furrow shallow. Each ostiole of ESES ellip-tical, opening posterolaterally; periostiolar depressions present; each peritrema spout-shaped, occupying about 1/3 of the distance to lateral margin of evaporatorium; medial furrow of the each ostiolar peritreme long, occu-pying more than half of the length of peritreme; evapora-torium punctate, occupying more than half of meso- and metapleuron; anterolateral margin of each evaporato-rium rounded; evaporatorium on mesopleuron reaching its anterior and posterior lateral angles, and surpassing the limits of mesocoxal sutures (Fig. 18J). Metathoracic spiracle wide (Fig. 18J, red arrow). Legs concolourous with abdominal venter (Figs. 8B, 9B, 12B). Length of femora and tibiae subequal; femora unarmed; tarsi 3-seg-mented. Scutellum longer than wide (Figs. 8A, 9A, 12A) and basal angles foveate. Corium longer than scutellum, surpassing apices of abdominal tergite 5. Membrane with veins linear. Hemelytra surpassing apex of abdomen. Abdomen: Connexivum exposed (Figs. 8A, 9A, 12A, 21C – D). Medial longitudinal groove on abdominal ven-ter reaching sternite 6 (Figs. 8B, 9B, 12B). Male terminalia (Figs. 10 A– N, 12G – I): Genital cup broad, open dorsoposteriorly. Ventral rim forming two layers, inferior and superior layers of ventral rim, not separated by a ca-rina; area between layers excavated. Superior layer of ventral rim projected toward genital cup, developed lat-erally to segment X, not covering parameres. Segment X not carinate, with processes. Parameres well-developed. Female terminalia (Fig. 11 A– C): Valvifers 8 convex. Valvulae 8 not visible. Laterotergites 8 lacking spiracles. Laterotergites 9 surpassing tergite 8 (Fig. 11A).

Distribution. Brazil: Amazonas, Rio de Janeiro and Par-aná (Fig. 17).

1 Outline of anterolateral margins of pronotum impunc-tate in dorsal view (Figs. 8A, 9A, 21A). Foveae on basal angles of scutellum relatively large, size equal to diameter of a compound eye (Figs. 8A, 9A, 21C). Sublateral margins of sternites lighter than of abdom-inal venter (Figs. 8B, 9B – C, 21F). Superior layer of ventral rim of pygophore with one pair of processes; lateral margin of each projection of superior layer of ventral rim notched (Fig. 10 A– B). Segment X rec-tangular, with one process, medially (Fig. 10I – K). .. ....................................... O. hypomelas (Burmeister)

1’ Outline of anterolateral margins of pronotum punc- tate in dorsal view (Figs. 12A,D, 21B). Foveae on ba- sal angles of scutellum relatively small, size less than diameter of a compound eye (Fig. 12A, 21D). Sub- lateral margins of sternites concolourous with disc of abdominal venter (Figs. 12B – C, 21G).
