“…However, given that the majority of wasps known from Cretaceous amber are often of smaller proportions (i.e., 12 mm or less) (e.g., Liu et al 2007; Engel and Grimaldi 2009; McKellar and Engel 2012; Engel et al 2013, 2017), and this is also true for coeval ants (e.g., Engel and Grimaldi 2005; McKellar et al 2013b, 2013c; Barden and Grimaldi 2013, 2014, 2016; Perrichot et al 2016; Barden et al 2017), one might conclude that the taphonomic bias is true. This is particularly evident when one considers that larger arthropod inclusions are certainly well known, with numerous such examples in these same resins (e.g., Grimaldi et al 2002; Engel and Grimaldi 2008), and certainly this is the case in the diverse Cenozoic ambers (e.g., Engel 1995, 2014; Engel and Grimaldi 2007). Thus, the result of such a taphonomic bias would be that there are any number of ‘ghost’ lineages and for which there assuredly should have been representatives in the Cenomanian (e.g., larger ichneumonoids, varied sizeable aculeates [such as scoliids], siricoid wood wasps, &c.).…”

A new braconid wasp from the Upper Cretaceous (Cenomanian) amber of the Hukawng Valley in Kachin State, Myanmar is described and figured from a unique female. Seneciobracon novalatus Engel & Huang, gen. et sp. n., is placed in a distinct subfamily, Seneciobraconinae Engel & Huang, subfam. n., owing to the presence of a unique combination of primitive protorhyssaline-like traits, with an otherwise more derived wing venation. The fossil is discussed in the context of other Cretaceous Braconidae.

“…A spectacular find was a taxonomically identifiable orchid pollinium attached to a worker of the fossil stingless bee Proplebeia dominicana (Wille et Chandler) in early Miocene (19–15 Ma) amber from the Dominican Republic (Ramírez et al 2007). Prior to this, orchid fossils had not been found from the Dominican Republic, although their presence was predicted by the occurrence of orchid bees (Euglossini) in the same Miocene deposits (Engel 1999) and the same is true for Mexican amber (Engel 2014). Many fossil bees preserved in amber, not only corbiculate bees, have pollen preserved in their scopae or corbiculae (e.g.…”

The middle Eocene Messel and Eckfeld localities are renowned for their excellently preserved faunas and diverse floras. Here we describe for the first time pollen from insect-pollinated plants found in situ on well-preserved ancient bees using light and scanning electron microscopy. There have been 140 pollen types reported from Messel and 162 pollen types from Eckfeld. Here we document 23 pollen types, six from Messel and 18 from Eckfeld (one is shared). The taxa reported here are all pollinated by insects and mostly not recovered in the previously studied dispersed fossil pollen records. Typically, a single or two pollen types are found on each fossil bee specimen, the maximum number of distinct pollen types on a single individual is five. Only five of the 23 pollen types obtained are angiosperms of unknown affinity, the remainder cover a broad taxonomic range of angiosperm trees and include members of several major clades: monocots (1 pollen type), fabids (7), malvids (4), asterids (5) and other core eudicots (1). Seven types each can be assigned to individual genera or infrafamilial clades. Since bees visit only flowers in the relative vicinity of their habitat, the recovered pollen provides a unique insight into the autochthonous palaeo-flora. The coexistence of taxa such as Decodon, Elaeocarpus, Mortoniodendron and other Tilioideae, Mastixoideae, Olax, Pouteria and Nyssa confirms current views that diverse, thermophilic forests thrived at the Messel and Eckfeld localities, probably under a warm subtropical, fully humid climate. Our study calls for increased attention to pollen found in situ on pollen-harvesting insects such as bees, which can provide new insights on insect-pollinated plants and complement even detailed palaeo-palynological knowledge obtained mostly from pollen of wind-pollinated plants in the dispersed pollen record of sediments. In the case of Elaeocarpus, Mortoniodendron, Olax and Pouteria the pollen collected by the middle Eocene bees represent the earliest unambiguous records of their respective genera.

“…The success of this work will be measured in the number of forthcoming discoveries stimulated by questions left open here. Euglossines hold a special place among corbiculate bees as they are the only group that is not eusocial and are putatively the earliest-diverging branch (e.g., Schultz et al, 1999Schultz et al, , 2001Engel, 2001b;Noll, 2002;Cardinal & Packer, 2007) within a clade that extends at least to the latest Cretaceous (e.g., Engel, 2000Engel, , 2001aEngel, , 2004Ohl & Engel, 2007), albeit available fossils of orchid bees are much younger (e.g., Engel, 1999Engel, , 2014Hinojosa-Díaz & Engel, 2007b;Michez et al, 2012;Dehon et al, in press). These realities coupled with their unique morphology, behavior, and intimate relationship with orchids makes them of paramount interest, particularly the diverse genus Euglossa which encapsulates 55% of the known species.…”

Abstract. The second and final part of a revision of the subgenus Euglossella Moure in the orchid bee genus Euglossa Latreille (Apinae: Euglossini) is presented here, redefining the species groups within it to comply with current morphological and molecular phylogenetic hypotheses. We present a fully illustrated account of the species comprising the newly defined viridis and mandibularis species groups, with comparable diagnoses for all species, keys to the new scheme of species groups within the subgenus, and keys for males and females to the species of the two groups here treated. The viridis group as presented here is composed of 12 species, five of them newly described -Euglossa (Euglossella) celiae Hinojosa-Díaz & Engel, new species, E. In total, considering the six species previously included in the decorata group, the subgenus now includes a total of 21 species. New country records are presented for E. viridis, E. perviridis, and E. mandibularis. Notes on morphological variation and distribution are included as is a summary of known chemical attractants and floral substrates.
