Ogmocoris paranaensis Frey-da-Silva et al., 2002: 183 – 185.

Diagnosis. Bucculae sinuous. Outline of anterolateral margins of pronotum punctate. Foveae in basal angles of scutellum relatively small, each less than the diameter of a compound eye. The outer margin of each metapleural evaporatorium convex; gyrification of evaporatorium with low wrinkles. Sublateral margins of sternites con- colourous with abdominal venter. Spiracles dark brown to black. Dorsal rim of pygophore without dorsal pro- cess; extension of dorsal rim over segment X obsolete. Superior layer of ventral rim with one pair of processes; lateral margin of each projection entire. Inferior layer of ventral rim with one pair of processes. Segment X ogival, with 1 + 1 tumescent processes basally.

Redescription. Measurements: Table 4. Colouration: General colour castaneous dorsally, with dense darkbrown to black punctures; ventral surface dark-brown to ferruginous, with dense concolourous punctures. Head reddish-castaneous, punctures on basal half brown, those on distal half concolourous. Antennomeres darkbrown. Labium yellowish-castaneous, apical labiomeres dark brown. Anterolateral margins of pronotum and lat- eral margins of coria castaneous; punctures dark brown. Pro-, meso-, and metasternum uniformly dark-brown to reddish-castaneous, densely punctate with dark-brown to black punctures. Legs reddish-castaneous. Connexivum brown, anterolateral angles with black spot, posterolater- al angles yellow. Sternites dark reddish-castaneous, with dark-brown punctures. Spiracles dark brown to black. Trichobothria reddish. Head ( Fig. 12A, D ): Anteocular processes absent. Proportions of antennomeres: 1> 2 <3> 4 <5. Bucculae sinuous ( Fig. 12E ). Thorax: Prono- tum with anterior angles produced; anterolateral margins concave, crenulate; humeral angles slightly developed ( Figs. 12A, D , 21B ). Gyrification of evaporatorium with low wrinkles; outer margin of each metapleural evapo-ratorium convex. Foveae in basal angles of scutellum relatively small, each less than the diameter of a com- pound eye ( Fig. 21D ). Apex of each radial vein con- spicuously calloused ( Fig. 21D , blue arrow) Abdomen: Posterolateral angles of each connexivum produced ( Fig. 21D , red arrow). Sublateral margins of abdominal ster- nites concolourous with abdominal venter, dark-brown to ferruginous ( Figs. 12A, C , 21G , blue arrow). Male terminalia: Dorsal rim of pygophore without dorsal pro- cess; extension of dorsal rim over segment X obsolete. Superior layer of ventral rim with one pair of processes; lateral margin of each projection entire ( Fig. 12H ). Infe- rior layer of ventral rim with one pair of processes ( Fig. 12I ). Segment X ogival, with 1 + 1 tumescent processes basally ( Fig. 12H ). Crown of paramere well-developed, spatulate ( Fig. 12H ).
