Type species. Luridocimex wygodzinskyi Grazia, Fernandes & Schwertner, 1998 by monotypy.

Diagnosis. Antennomere 4 cylindrical and convex dorsally. Mesosternum grooved. Inferior layer of ventral rim of pygophore with a process. Valvifers 9 depressed. Posterior margins of laterotergites 8 acutely projected. Laterotergites 9 convergent.

Redescription. Body oblong (Figs 114, 136–137). General coloration yellowish-brown. Dorsal surface of body flattened dorsoventrally (Fig. 18). Dorsal body surface with dense and ferruginous punctuation, ventrally, in more numbers. Mandibular plates longer than clypeus; lateral margins of mandibular plates sinuous; mesial margins of mandibular plates contiguous in relation to the clypeus, apically convergent (Fig. 3). Clypeus wider basally. Antennomere 2 smaller than 1; antennomere 3 cylindrical and dorsally convex; antennomere 4 cylindrical, convex dorsally. Bucculae tapering toward base of head, not reaching its base. Labiomere 2 cylindrical and smaller than 3 and 4 combined in length (Fig. 7). Anterolateral margins of pronotum convex, with outline concolour to pronotum and evenly punctate. Posterolateral margins of pronotum sinuous. Posterior margin of pronotum slightly convex (Figs 3, 114, 136). Mesosternum with longitudinal groove. Each ostiole of ESES guttiform; periostiolar depressions present (Fig. 138). Callosity at apex of radial vein pale yellow, small or faint (Figs 137, 139). Membranal suture sub-rectilinear. Connexivum exposed, angles brown. Spiracles circular, black (Figs 18, 137, 139). Trichobothria laterally to the imaginary line tangent to the spiracles.

Male genitalia. Pygophore subquadrangular, as wide as long. Segment X “pear-shaped”, with tumescent processes basally (Figs 33–35, 140–142).

Female genitalia. Valvifers 8 convex. Each lateral margins of valvifers 9 with process, partially covering the laterotergites 9, forming a constriction. Laterotergites 9 surpassing abdominal tergite 8 (Fig. 50).

Distribution. Brazil (Rio de Janeiro) (Fig. 184).
