Abstract

Two new wasp species of Burmusculidae, Burmusculus abstrusus sp. nov. and Burmusculus primitivus sp. nov. are described from mid-Cretaceous amber of Myanmar. The new species are attributed to the family Burmusculidae and share the typical combination of diagnostic features of this family: forewing 2-M moderately short and distinctly angled with Rs+M and mesopleuron with no oblique sulcus. We observe variation in the presence/absence of plantulae on the tarsomeres of Burmusculus spp. and recommend that this character is included in species diagnoses in Burmusculidae. Tarsal plantulae are also observed in Pompilidae, the closest modern relatives of Burmusculidae.
