The fauna of bees known from Early Eocene (Ypresian) Cambay amber are reviewed.  Presently only three species have been recovered, all from among the corbiculate Apinae and representing the extinct tribes Electrapini and Melikertini, and all from genera known from the slightly younger middle Eocene Baltic amber.  A single, poorly-preserved and fragmentary female of an unidentifiable species of Protobombus Cockerell is recorded.  Two new species of the genus Melikertes Engel are documented, one representing a new subgenus, Paramelikertes Engel & Ortega-Blanco, as is a third, fragmentary melikertine of uncertain identity.  The new species are Melikertes (Paramelikertes) gujaratensis Engel & Ortega-Blanco, new species, and M. (Melikertes) kamboja Engel & Ortega-Blanco, new species.

Two new species of larger benthic foraminifera, Neorotalia omanensis n. sp. and Operculina musawaensis n. sp. are described and illustrated from the eastern Oman Mountains. N. omanensis n. sp. occurs in the Musawa Formation in association with the planktonic foraminifera Morozovella edgari and Truncarotaloides topilensis indicating an early to middle Eocene age (P10-P13). Operculina musawaensis n. sp. occurs in the Abat Formation in association with the planktonic foraminifera Acarinina esnaensis and A. soldadensis indicating an early Eocene age (P6).  This is the first known record showing the presence of genus Neorotalia in the Middle East. Representatives of the larger foraminiferal genus Linderina sp. are also described and illustrated from the Musawa Formation and compared with the published Linderina species in the surrounding countries.

The family Discidae has undergone extensive speciation in the Macaronesian region (eastern Atlantic Ocean), with 11 endemic species recognised from Madeira and the Canary Islands in recent checklists (Bank, Groh & Ripken 2002; Seddon 2008; Fauna Europaea database project 2011), grouped into the genera Keraea Gude, 1911 and Discus Fitzinger, 1833: K. deflorata (R.T. Lowe, 1855) and D. (Atlantica) guerinianus (R.T. Lowe, 1852), from Madeira; and nine species from the Canary Islands: K. garachicoensis (Wollaston, 1878), D. scutula, (Shuttleworth, 1852), D. engonatus (Shuttleworth, 1852), D. textilis (Shuttleworth, 1852), D. retextus, (Shuttleworth, 1852), D. putrescens (R.T. Lowe, 1861), D. ganodus (J. Mabille, 1882), D. gomerensis Rähle, 1994, and D. kompsus (J. Mabille, 1883). In contrast with the anatomical data known for the European and North American genera Discus and Anguispira Morse, 1864 (Uminski 1962; Pilsbry 1948), there has hitherto been no information published on the internal anatomy of the Canary Islands and Madeiran species, which are known only by their shell characters. In this paper we raise Atlantica to the rank of genus in the Discidae and describe shell and anatomical characters for two new species from La Gomera and Tenerife, respectively. They are grouped in a new subgenus of Atlantica, largely restricted to the laurisilva. This laurel-rich forest occurs in humid subtropical and warm-temperate regions with little variability in temperatures and is developed between 600 and 1,200 m above sea level in the Canary Islands (Yanes et al. 2009b: Fig. 2).

A molecular phylogeny of the western Palearctic weevil genus Kyklioacalles Stüben, 1999 is presented, combining two mitochondrial genes (CO1 and 16S) in a Bayesian analysis. Based on molecular data, the validity of the subspecies Kyklioacalles punctaticollis punctaticollis (Lucas, 1849) and Kyklioacalles punctaticollis meteoricus (Meyer, 1909) is discussed and the morphological differentiation of the endophalli and known distributions of both subspecies are verified. Glaberacalles subg. n. (formerly Kyklioacalles punctaticollis-group) and two new species are described, Kyklioacalles atlasicus sp.n. from Morocco and Kyklioacalles plantapilosus sp.n. from Spain. Kyklioacalles berberi (Stüben, 2005), comb. n. and Kyklioacalles olcesei (Tournier, 1873) comb. n. are transferred from Acalles Schoenherr. The molecular results further advocate a transfer of Onyxacalles pyrenaeus (Boheman, 1844) to Kyklioacalles; however this is not supported by morphological evidence. Kyklioacalles almadensis Stüben, 2004 syn. n. (Spain) is synonymized with Kyklioacalles bupleuri Stüben, 2004 (Tunisia). A catalogue of all 40 (sub-)species of Kyklioacalles is given and a key of the species of the subgenus Glaberacalles is presented.

Marksomyia is proposed as a new subgenus of the genus Culicoides Latreille to embrace six species from Australia and New Guinea. Comparative descriptions of males and females of C. zentae sp. nov. and C. kayi sp. nov., pupae of C. zentae and redescriptions of C. marksi Lee & Reye, C. dycei Lee & Reye, C. parvimaculatus Lee & Reye and C. pseudostigmaticus Tokunaga are presented together with distributional data and keys for their specific determination. The designated type species of the subgenus is C. marksi. Marksomyia is further subdivided into three species complexes based on the shape and sclerotisation of the spermathecae.

Two new species of Eurypinae (Coleoptera: Mycteridae) are described from Eocene Baltic amber from the Kaliningrad Region, Russia: Glesoconomorphus nachzehrer gen. et sp. nov. and Omineus febribilis sp. nov. The first new fossil taxon displays affinity to recent members of the Neotropical Conomorphus-Stilpnonotus lineage, and the second species was placed into the present-day eastern and southeastern Asian genus Omineus Lewis. The fossil Neopolypria nigra Abdullah, 1964 (Baltic amber) is moved from Mycteridae and placed as incertae sedis within Tenebrionoidea Latreille, 1802.

Extraordinarily diverse morphologically and ecologically, Lake Baikal’s two endemic gammaroidean amphipod clades are both firmly placed within the paraphyletic genus Gammarus, based both on morphological and molecular characters. However, the exact placement of the two Baikal clades remains elusive, making reconstruction of the ancestral state of Baikal endemic radiation difficult. We sequenced 2 mitochondrial and 3 nuclear genes from several species of each of the two clades aiming to represent early branches of the radiation. We also describe two new species of Baikal gammarids, Eulimnogammarus etingovae sp. nov. and Eulimnogammarus tchernykhi sp. nov., with some morphology suggestive of basal position within the radiation. We confirm the two previously demonstrated Baikal clades, but cannot unequivocally support any of the previous hypotheses about affinities of the two Baikal clades within palearctic Gammarus species. Rather, it appears that the two Baikal endemic radiations separated from the rest of freshwater Palearctic forms early and rapidly, probably as part of gammarid diversification during colonization of fresh waters in Middle Eocene.

We describe Paleothrypticus eocenicus gen. et sp. nov., oldest and first Medeterinae from the Early Eocene Oise amber (France). Representatives of the tribes Medeterini and Systenini are recorded in the Middle Eocene Baltic amber and the Miocene amber of Mexico. These fossils show that this subfamily was already well diversified at the beginning of the Eocene.
