Type locality. Brazil, Rio de Janeiro, Teresópolis (coordinates -22.4241, -42.9680).

Male Holotype. Labels: Terezopolis, E. do Rio, Brasil; Zajciv, coll. 1956 (MNRJ)

Description. Body broadly oval, copperish brown with dark brown to black punctures. Head and anterior margin of pronotum darker than the remaining dorsal surface; lateral margin of mandibular plates, anterior and anterolateral margins of pronotum, and anterior half of the lateral margin of coria lined in black. Body surface bearing sparse, short setae densely distributed on abdominal venter.

Head declivous, slightly longer than wide; lateral margins of mandibular plates sinuous and slightly elevated, without projections before the eyes. Mandibular plates and clypeus subequal in length, round at apex. Middle of clypeus tumescent. Ocelli small, the diameter of each ocellus less than twice the diameter of one puncture. Ocelli placed behind an imaginary line connecting the posterior limit of eyes (Fig. 7 A, D); interocellar distance about 4.5 times the distance between each ocellus and the nearest eye. Eyes small, width of each eye less than? the width of head across the eyes. Antennae brown; antennal tubercles not visible in dorsal view (Fig. 7 A). Bucculae rounded anteriorly, evanescent posteriorly attaining the base of head. Labium light brown; first segment reaching prosternum, second segment slightly surpassing mesocoxae, third surpassing urosternite III, and the fourth segment attaining urosternite VI.

Pronotum irregularly punctured, transversally striated; cicatrices conspicuous, slightly tumescent. Anterolateral margins almost straight; anterior half of anterolateral margins crenulate; anterolateral angles projected laterad of eyes by half the width of one eye. Humeral angles rounded. Scutellum almost 1.2 times longer than wide at base, attaining the level of middle of connexivum V; apex broadly rounded. Frenal and postfrenal portions of scutellum subequal in length. Punctures denser than on pronotum, and smaller and denser near the apical margin of scutellum; black fovea present in basal angles. Hemelytra regularly punctured; punctures denser than on scutellum; apex of each corium setose. Trocanthers and base of femora light brown, tibiae and tarsi dark brown; tibiae with dorsal, shallow sulcus.

Connexivum exposed, dark brown, bearing shallow punctures and short setae. Posterolateral angles of urosternites round. Ventral abdomen copperish, densely setose except at middle of sternites III to VI. Urosternites III to V longitudinally depressed at midline. Trichobothria lateral of imaginary line tangent to lateral margins of spiracles IV to VI.

Male genitalia. Pygophore globose; posterolateral angles poorly developed, broadly rounded (Fig. 8 A, B, pa). Dorsal rim concave, bearing 1+1 short projections near base of segment X (Fig. 8 A, C, D, dr, p1), and 1+1 long, laminar projections lateral to segment X (fig 8A,C, D, p2). Inferior layer of ventral rim broadly concave (Fig. 8 B, vr, il); superior layer of ventral rim with 1+1 large laminate projections lateral to segment X, partially covering the parameres both in posterior and in dorsal views (Fig. 8 A–G, vr, sl, p3). Parameres long and falciform, projecting anterolaterally lateral to segment X and curving about 90° posterolaterally over the laminate projections of the dorsal rim (Fig. 8 A–G, par). Segment X broad, membranous at basal ¾, emarginate at apex (Fig. 8 A–G, X).

Measurements. (n=1) head length 2.00; width 2.10; interocular distance 1.30; pronotum length 2.44; width 6.17; scutellum length 3.85; width 3.45; length of antennomeres: I 0.52, II 0.60, III 0.94; length of labium segments: I 1.17, II 2.01; III 1.70, IV 1.55; length of abdomen 4.41; width 5.78; total length 9.00.

Comments. Ocellatocoris longirostris is described in Ocellatocoris Campos & Grazia based on the following characters: the shape of the head; the proportionately small eyes; the short setae covering most of the body; the shape of the pronotum, particularly the anterolateral margins crenulated and transversly striated; the proportions of the scutellum; the shape of the evaporatorium and peritreme; and the structure of the meso- and metasternum. Ocellatocoris was described for O. dasys Campos & Grazia, known only from the female holotype (Campos & Grazia, 2001). Though the male of O. dasys remains unknown, we describe Ocellatocoris longirostris on the basis of the following morphological differences: the smaller body (total length 8.7 in O. longirostris and 13.4 in O. dasys); the relatively longer rostrum, surpassing the anterior margin of urosternite VI in O. longirostris while only attaining the anterior margin of urosterite V in O. dasys; the sparser setae on coria of O. longirostris; and the absence of 1+1 lateral light brown stripes on urosternites III to V in O. longirostris which are present in O. dasys.
