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
