Coleopterocoris hungerfordi De Carlo, 1968: 194 ; Van Doesburg, 1984: 19

Measurements (male / female). Body length: 3.43 / 3.43–3.50; maximum width of body: 2.05 / 1.95–2.00; maximum width of head: 0.77 / 0.72–0.74; length of head: 0.58 / 0.48–0.51; anterior width of pronotum: 0.80 / 0.80–0.86; posterior width of pronotum: 1.44 / 1.52–1.54; length of pronotum: 0.35 / 0.32–0.38; length of scutellum: 0.58 / 0.56–0.58; interocular width: 0. 40 / 0.39–0.40; eye width: 0.18 / 0.17–0.18.

Diagnosis. Head with numerous thin setae around eyes and on anterior region; eyes projected laterally. Pronotum with many thin setae on lateral edges; anterior portion of hemelytra with more setae than posterior one; forefemora cylindrical, not dilated. Male with apex of genital operculum obtuse to rounded; basal plate triangular, with subacute apex, subequal to or longer than paramere; parameres dilated at base, narrowing gradually toward apex and curved inward at mid­length.

Redescription

General color dark brown. Anterior region of hemelytra lighter than posterior region.

Body robust. Head with numerous thin setae around eyes and on anterior region; eyes projected laterally. Pronotum with many thin setae and well­marked punctures on lateral edges; scutellum and hemelytra surfaces with well­marked punctures; hemelytra quite

transparent, the hind wings visible through them ( Fig. 9); anterior region of hemelytra with more setae than posterior one; forefemora cylindrical, not dilated ( Fig. 13, FEM).

Male genitalia. Apex of genital operculum obtuse to rounded ( Fig. 10, GOP); basal plate triangular, apex subacute, subequal to or longer than parameres ( Fig. 11, BAS); parameres arched and dilated basally, narrowing gradually toward apex; some specimens with parameres crossed distally ( Fig. 11, PAR).

Female genitalia. Genital operculum obtuse, with apex truncated ( Fig. 12).

Comments. Coleopterocoris hungerfordi differs from C. nelsoni n. sp. and C. kleerekoperi in possessing a more robust body, eyes projected laterally with numerous setae around them, and forefemora cylindrical, not dilated. In addition, these three species can be distinguished by features of the male genitalia. In C. hungerfordi specimens the parameres are dilated basally, narrowing gradually toward the apex ( Fig. 11); in C. kleerekoperi the parameres are right­angled upward near mid­length and have a constriction near the apex, whereas in C. nelsoni the parameres are right­angled upward near the mid­length but are of the same width at all extension ( Figs. 5–6).

Distribution ( Fig. 14). Coleopterocoris hungerfordi has been reported from the Brazilian States of São Paulo and Paraná ( De Carlo 1968). The known distribution of this species now includes the State of Rio de Janeiro, Municipality of Nova Friburgo, Lumiar [22 o 22’ 0” S, 42 o 12’ 0” W] and Municipality of Macaé, Sana [22 o 23’ 60” S, 42 o 10’ 60” W].
