A fossil species of the primitive mymarid genus <i>Borneomymar</i> (Hymenoptera: Mymaridae) in Eocene Baltic amber

Abstract

Abstract.A new fossil species of fairyfly (Hymenoptera: Chalcidoidea: Mymaridae) is described and figured from a well-preserved female in middle Eocene (Lutetian) Baltic amber as Borneomymar pankowskiorum Engel, McKellar, & Huber, new species. This species represents the fourth genus from Baltic amber whose extant species now occur only in southeastern Asia,

Two New Species ofPterydriasReitter (Coleoptera: Ripiphoridae), Significantly Expanding the Biogeographic Range of the Genus

“…Nonetheless, the observed distributions, particularly those between Europe and sub-Saharan Africa and southern Asia, are commonly found among many groups (Grimaldi and Engel 2005), especially when looking at lineages surviving in the latter regions and known from Tertiary fossils in the former (e.g., Ander 1942;Böhme and Weitschat 1998;Engel 2001;Engel et al 2007Engel et al , 2013aPadayachee and Procheş 2016), or even strictly fossil lineages that link the past fauna of Europe with southern Asia (e.g., Grimaldi and Singh 2012;Engel et al 2013b). It is likely that several ripidiine genera or more inclusive clades were widespread during parts of the Tertiary and have subsequently become more restricted in distribution.…”

First described fossil representatives of the parasitoid wasp taxa Asaphesinae n. n. and Eunotinae (Hymenoptera: Chalcidoidea: Pteromalidaesensu lato) from Eocene Baltic amber

“…The discovery of fossil taxa also provides a better context for investigating the age of pteromalid subgroups. Recently described verifiable Baltic amber chalcidoid taxa include fossil species from otherwise extant genera such as Metapelma Westwood (Eupelmidae: Neanastatinae) (Gibson 2009), Perilampus Latreille (Perilampidae) (Heraty and Darling 2009), Borneomymar Huber (Mymaridae) (Engel et al 2013), Centrodora Förster (Aphelnidae), Mirufens Girault, Pterandrophysalis Novicky, and Szelenyia Novicky (Trichogrammatidae) (Burks et al 2015). New Baltic amber genera have been described from Neanastatinae (Eupelmidae) and Tanaostigmatidae (Gibson 2008(Gibson , 2009, Psilocharitini (Eucharitidae) (Heraty and Darling 2009), Aphelinidae, Trichogrammatidae (Burks et al 2015), and Cerocephalinae and Herbertiinae (Pteromalidae sensu lato) (Bläser et al 2015;Burks et al 2018).…”

A new lineage of Cretaceous jewel wasps (Chalcidoidea: Diversinitidae)

“…Numerous chalcidoid fossils have been reported from different amber deposits ( Grimaldi & Engel, 2005 ; Penney, 2010 ), but few of them have been formally described. Most described chalcidoids stem from young (Eocene and Miocene) deposits, which already host an astonishing phylogenetic diversity of taxa ( Darling, 1996 ; Gibson, 2008 ; Gibson, 2009 ; Gibson, 2013 ; Engel, 2009 ; Engel, McKellar & Huber, 2013 ; Heraty & Darling, 2009 ; Compton et al, 2010 ; McKellar & Engel, 2012 ; Krogmann, 2013 ; Simutnik, Perkovsky & Gumovsky, 2014 ; Bläser, Krogmann & Peters, 2015 ; Burks et al, 2015 ; Farache et al, 2016 ). It is believed that most chalcidoid families diversified after the Upper Cretaceous ( Heraty et al, 2013 ; Peters et al, 2018 ) during a period that falls within a major gap in the chalcidoid fossil record, from which only few taxa have been described or even discovered ( Burks et al, 2015 ; Heraty & Darling, 2009 ; Penney, 2010 ).…”
