Embolemopsis is an extinct genus of wasps belonging to the family Embolemidae. Two species are known: the type species, E. baissensis from the Aptian Zaza Formation of Russia,[1] and E. maryannae from the Barremian Wessex Formation of England.[2]

Discovery and naming

[edit]

The holotype of E. baissensis, PIN 4210/7295, was discovered in Baissa, Russia within an outcrop of the Zaza Formation and was named described by Olmi et al. (2010) within a revision of the Dryinidae and Embolemidae.[1]

The holotype, and only specimen, of E. maryannae was discovered in Chilton Chine, England in the L6 plant debris bed of the Wealden Formation,[2] and before being named, E. maryannae was previously described as a member of the Dryinidae in a conference abstract by Jarzembowski (2015).[3] Between 2017 and 2019, E. maryannae was classified instead as a member of the Embolemidae, and was named by Olmi et al. (2020) alongside six other extinct members of the Embolemidae.[2] It was named in honour of Mary Anning.

Description

[edit]

E. baissensis grew to around 2.60 millimetres (0.102 in) long.[1]

Classification

[edit]

Jarzembowski (2015) classified E. maryannae within Dryinidae,[3] and Olmi et al. (2020) later placed both species of Embolemopsis within Embolemidae.[2]
