DIAGNOSIS.
This species (
Figs. 55–57
) is recognized by the transverse yellow to yellowish-brown fascia along the posterior margin of the vertex and the bluish sheen on the hemelytra.
It is most similar to
N. longirostris
in sharing a flattened body, overall black color including the antennae and legs, and the relatively thick first and second antennal segments, but is larger, has a pale transverse band on the vertex, the labium is much shorter, and the genital tubercle (
Fig. 133
) is stouter and apically rounded.
Nigrotomocoris keltoni
and
N. tibiopallidus
differ from and
N. longirostris
and
N. nigrus
in having a less flattened body and C-shaped left parameres (versus L-shaped parameres);
N. keltoni
also has the white pleural patches and a more spinelike genital tubercle (
Fig. 131
) and
N. tibiopallidus
has pale tibiae and antennal segments.
