Nauphoeta
speckled cockroach, lobster cockroach, cinereous cockroach
Nauphoeta is a monotypic genus of cockroaches in the family Blaberidae, containing the single species Nauphoeta cinerea. The genus is notable for its well-studied social behavior, including male territoriality and dominance hierarchies. Nauphoeta cinerea has become a widely used laboratory model organism for behavioral, physiological, and toxicological research, and has achieved a circumtropical distribution through human-mediated dispersal.
