Abstract
The study on faunal diversity o f Non- Apis bees (Super family: Apoidea) in and
around western gnat region from places like Shimoga, Chikkamagalur, and Kodagu
Districts revealed 47 species in 13 genera under 4 families viz., Apidae, Halictidae,
Meghachilidae, and Collitidae and 6 sub-families viz., Apinae, Xylocopinae, Halictinae,
Nominae, Meghachilinae, and Hylaeinae. The genera included under the study are
Braunsapis Michener, Heriades Spinola and Anthidellum Cockerell one species each,
Thyreus Jurine and Halictus Latreille two species each, Amegilla Friese, Ceratina
Latreille and Meghachile Latreille. five species each, Lassioglosum Curtis and Nomia
Latreille 4 species each, Coelioxys Latreille 3 species and Xylocopa Latreille 10 species.
All these species were collected while foraging on 22 different plant species. Each o f the
specimens are described and illustrated. Keys are also given for their identification. All
these species are useful to mankind as pollinators. Amegilla Friese pollinates Thumbe,
Adathoda, Balsam; Cerantina Latreille pollinates cucumber, ridge guard and bitter guard
and Xylocopa Latreille pollinates beans, ridge guard, glyricidia and ankola. Meghachile
Latreille pollinates datura, kuphia, lakki, techoma and pongamia. The bee diversity was
higher at Shimoga dist followed by Chikkamagalore and Kodagu dists.
