Rihirbus is a genus of assassin bug from the tropical parts of the Oriental region. They belong to the Harpactorinae and the genus is unique in having the fore tibiae with incurved tips and the apex having a long tooth. They show sexual dimorphism and are polymorphic making their identification to species complicated. Females are larger and wider. R. trochantericus takes about 49 days to develop from egg to adult in southern India. [1]

The genus Camptibia has an incurved tip to the foretibia, but lacks subapical teeth. [2] The head is shorter than the pronotum and the base of the antenna has a spine behind it. The antennal scape is about as long as the head, pronotum and scutellum put together. They show considerable polymorphism and sexual dimorphism and in the past a number of species have been described but only three are currently recognized. [3]

Apiomerus is a genus of conspicuous, brightly colored assassin bugs belonging to the family Reduviidae. The species can be found in the United States ranging into tropical America. The common name bee assassins derives from their frequent habit of sitting and waiting upon flowers and taking bees as prey. The bright colors are aposematic, likely a warning to larger predators that a painful bite can be delivered.
