Palaeosiamoglaris hkamtiensis sp. nov. of the family Prionoglarididae is described from Hkamti amber (ca. 110 Ma), together with Psyllipsocus myanmarensis nov., third fossil psyllipsocid species Noije Bum Hill 98 Ma). Based on current observations we discuss synapomorphic characters proposed to define tribe Siamoglaridini. is, inter alia, characterized by maxillary palpomere 3 ca. 0.66 times as long 4, second anal vein concavity turned toward posterior wing margin in forewing, Sc reaching R1 nearly at middle radial cell. The new antennae 11 segments, cell closed and six-angled, quadrangular pterostigma.

The fossil psocodeans from Late Cretaceous (Cenomanian to Santonian) amber of Vendée, in northwestern France, are studied. Two new genera and three new species are described and illustrated, as Proprionoglaris axioperierga n. sp. (Archaeatropidae), Scocompus atelisus n. gen. and sp.

متن کاملA fossil bee from Early Cretaceous Burmese amber.
The bee fossil record is fragmentary, making it difficult to accurately estimate the antiquity of bee-mediated pollination. Here, we describe a bee fossil [Melittosphex burmensis (new species), Melittosphecidae (new family)] from Early Cretaceous Burmese amber (approximately 100 million years before the present). The fossil provides insights into the morphology of the earliest bees and provides...
متن کاملCretevania bechlyi sp. nov., from Cretaceous Burmese amber (Hymenoptera: Evaniidae).
The fossil evaniid wasp Cretevania bechlyi sp. nov., is described based on a well preserved female specimen from Cretaceous Burmese amber. The new species is placed in the genus Cretevania Rasnitsyn, 1975 based on the elongation of the mid and hind trochantellus, the fore wing venation (e.g. first marginal cell triangular and broad, 2m-cu absent, second sub-marginal cell separated from first di...
متن کاملMummified precocial bird wings in mid-Cretaceous Burmese amber
Our knowledge of Cretaceous plumage is limited by the fossil record itself: compression fossils surrounding skeletons lack the finest morphological details and seldom preserve visible traces of colour, while discoveries in amber have been disassociated from their source animals. Here we report the osteology, plumage and pterylosis of two exceptionally preserved theropod wings from Burmese amber...
