Abstract

The material for this paper was the author’ research during the expedition in the Zanzibar in January and February 2014. The Zanzibar archipelago includes group of islands off the coast of mainland Tanzania in the Indian Ocean (Zanzibar, Pemba etc.). The Zanzibar or Unguja is major island of the Zanzibar archipelago. It is located in the subequatorial physical-geographical belt. The beetles were collected in Mwera river and canals in rice paddies. During the research, 10 species of water Adephaga (from 2 familes, 8 genera) from Unguja island were found. Nine species of Dytiscidae and one species Noteridae from Zanzibar are presented. The largest number of species (5) was reported from subfamily Hydroporinae. For the first time Canthydrus notula (Erichson, 1843), Bidessus sharpi Régimbart, 1895, Clypeodytes meridionalis Régimbart, 1895, Hydroglyphus farquharensis (Scott, 1912), Uvarus gschwendtneri (Guignot, 1942), Hydrovatus acuminatus Motschulsky, 1859, Laccophilus adspersus Boheman, 1848 are recorded for Unguj island and Zanzibar archipelago fauna. All these species are found on mainland Tanzania The article illustrates the habitats of all species of aquatic beetles on Zanzibar, as well as the habits of species of the diagnostically difficult genus Laccophilus (L. adspersus, L. continentalis Gschwendtner, 1935 и L. cf. canthydroides Omer-Cooper, 1957).
