Identification
In the Apiomerini (which contains the most commonly confused genus Apiomerus), the first antennal segment is shorter than the head, the ocelli are farther apart than the eyes and the tarsal claws are simple. In Rhynocoris (and Harpactorini in general), the first antennal segment is longer than the head, the ocelli are situated more closely than the eyes and the tarsal claws are dentate or appendiculate.
Rh. ventralis: Body and legs largely red or yellow;
Rh. leucospilus: Black, with yellow spots on sides of abdomen only
Range
Worldwide; in our area, R. ventralis widespread across the US, the Palaearctic R. leucospilus known from Sitka, AK
Remarks
On a worldwide scale, this genus has been used in the past as a "dumping ground" for harpactorine assassin bugs.
