The first fossil Embolemidae (Hymenoptera: Chrysidoidea) from Burmese amber (Myanmar) and Orapa Kimberlitic deposits (Botswana) and their phylogenetic significance

摘要

Ampulicomorpha janzeni sp. nov. and Cretembolemus orapensis gen. et sp. nov. are described from Burmese amber (Upper Cretaceous; Lower Cenomanian) and Orapa sediments (Upper Cretaceous; Turonian), respectively. A. janzeni is the first embolemid species found in amber from Myanmar (c. 99 Ma). C. orapensis is the first fossil embolemid species found in the southern hemisphere, in Orapa Kimberlitic deposits (c. 91 Ma). A discussion on the phylogenetic significance of the above new records is presented, together with a tentative history of Embolemidae and their relations with their hosts. The new combinations Ampulicomorpha perialla (Ortega-Bianco et al., 2011) comb. nov. (= Embolemus periallus) and Ampulicomorpha reticulata (Van Achterberg in Van Achterberg & Van Kats, 2000) comb. nov. (= Embolemus reticulatus) are proposed.
