BIODIVERSITY OF NABICULA KIRBY SPECIES (HEMIPTERA: NABIDAE) IN CANADA: FAUNISTIC REVIEW, BIOECOLOGY, BIOGEOGRAPHY

Abstract

AbstractSeven species of Nabicula Kirby occur in Canada: N. americolimbata (Carayon), N. flavomarginata (Scholtz), N. limbata (Dahlbom), N. nigrovittata nearctica (Kerzhner), N. propinqua (Reuter), N. subcoleoptrata Kirby, and N. vanduzeei (Kirkaldy), of which N. limbata is officially recorded for the first time for North America. A faunistic review of the species, key to all taxa, generic diagnosis, and characters distinguishing male and female last-instar nymphs are presented. As appropriate for each species, die following are provided: synonymy, description of adult, wing polymorphism, taxonomic comments, detailed geographical distribution, bioecology, and illustration of important structural characters and nymphal instars. The last-instar nymphs of N. americolimbata, N. nigrovittata nearctica, N. propinqua, N. subcoleoptrata, and N. vanduzeei are described and illustrated for the first time. The biogeography of Nabicula is considered with regard to species diversity patterns, ecological assemblages, species distribution patterns, and relationships between macroptery and geographical distribution.
