Reduvius sonoraensis

Usinger, 1942

Reduvius sonoraensis is a of assassin bug in the Reduviidae. It is known to occur in Central America and North America. A distinctive feature of this species is the presence of two morphological types discernible by the fifth instar: individuals with short wing pads and those with long wing pads. This wing pad dimorphism represents an unusual developmental within the Reduvius.

Identification

The fifth instar nymphs can be distinguished by two distinct morphological types based on wing pad development: those with short wing pads and those with long wing pads. This dimorphism provides a key diagnostic character for recognizing the during late nymphal stages.

Central America and North America.

Life Cycle

Nymphs develop through five instars. By the fifth instar, two distinct morphological types are present, differing in wing pad length. The functional significance of this wing pad dimorphism remains unclear.

  • Reduvius personatusBoth are congeneric assassin bugs in the Reduvius, but R. personatus (Masked Hunter) is distinguished by nymphs that actively cover themselves in debris for camouflage—a not reported for R. sonoraensis. R. personatus also lacks the wing pad dimorphism characteristic of R. sonoraensis fifth instars.
