A new genus and species of Berothidae is described from the Late Cretaceous (Cenomanian) Myanmar amber. Ansoberothajiewenaegen. et sp. nov. can be easily distinguished from other berothid genera by the long antenna, the scape with ca. 100 flagellomeres, the forewing with four ra-rp, MPand CuA are pectinately branched, and the hind wing with one oblique cua-cup between CuA stem and the distal branch of CuP.

A new genus and species of basal cyclostome Braconidae is described and figured from a male preserved in mid-Cretaceous amber from northern Myanmar.  <strong><em>Rhetinorhyssalus morticinus</em></strong> Engel, new genus and species, is interesting for its combination of primitive features such as a minute apical costal cell and anal stubs in the forewing, while lacking 2Cu in the hind wing, a putatively derived trait.  As such, the genus may represent a lineage diverging from the braconid stem subsequent to many protorhyssalines, while remaining basal relative to generalized cyclostome groups such as Rhyssalinae.  In addition, the Late Cretaceous <em>Diospilus allani</em> Brues, in Campanian Canadian amber, is transferred to <strong><em>Diorhyssalus</em></strong> Engel, new genus, and its similarity to <em>Rhetinorhyssalus</em> is discussed.  This transfer results in the new combination, <em>Diorhyssalus allani</em> (Brues).  Both genera are tentatively considered as subfamily <em>incertae sedis</em>.

New Genus And Species

A new genus and species of Sisyridae, Stictosisyrapennyi gen. et sp. n., is described from the Late Cretaceous (earliest Cenomanian/late Albian) Myanmar amber. It can be easily distinguished from other sisyrids genera by the configuration of wing venation such as forewing with four ra-rp crossveins, M forked distal to the separation of RP1, CuA pectinate and CuP simple; hind wing 1r-m long and sinuous. Besides, the newly documented spongillaflies bore distinct, irregularly distributed spots on the forewings.

The Relationship

A new genus and species of the lacewing family Psychopsidae, Electropsychops handlirschi gen. et sp. nov., is described based on a well preserved male specimen from the mid-Cretaceous amber of Myanmar. The new genus possesses a number of diagnostic characters of Psychopsidae, i.e., the lack of a forewing median nygma, the presence of a vena triplica, and the straight and barely forked RA. However, it also exhibits some remarkable characters that are present in Osmylopsychopidae, such as the distally narrowed forewing costal space and the sigmoid MA stem in the hind wing. The relationship between Psychopsidae and Osmylopsychopidae is briefly discussed.

A New Species

Leafhoppers of the Eupteryx-complex differ from other members of the tribe Typhlocybini in having the posterior branch of hind wing vein R separate from the anterior branch of M (Young 1952). The complex now includes 9 known genera of which 5 genera, Aguriahana Distant 1918, Eurhadina Haupt 1929, Eupteryx Curtis 1833, Caknesia Dworakowska 1994, Almunisna Dworakowska 1969 and Bellpenna Chiang et al 1989, have been reported from China. Here we propose a new genus Comahadina Huang and Zhang which shares the hind wing character with other genera in the complex, based on a new species, Comahadina angelica Huang and Zhang, here designated as the type-species. The new genus and species are described and illustrated and a key to all genera of the Eupteryx-complex is provided.

The proctotrupoid wasp family Pelecinidae (Proctotrupomorpha: Proctotrupoidea) is recorded in Early Cretaceous amber for the first time, previous amber inclusions being from the Late Cretaceous or Tertiary. Zoropelecinus zigrasi Engel & Grimaldi, new genus and species, is described and figured from an exquisitely preserved female in Albian-Cenomanian amber from Myanmar. The genus is similar to other fossil pelecinids of the genera Pelecinopteron Brues (Paleogene ambers of the Baltic and Siberia) and Henopelecinus Engel & Grimaldi (Turonian amber, New Jersey). Although two subfamilies have at times been recognized (or even as two families) the Iscopininae are clearly paraphyletic with respect to Pelecininae and therefore of no classificatory value and accordingly synonymized herein (new synonymy).

ABSTRACTA new rhynchonellide brachiopod has been collected from the Kahuitara Tuff (Campanian–Maastrichtian) of Pitt Island, Chatham Islands, New Zealand. Brachiopods are extremely rare in Cretaceous rocks from New Zealand, and this new genus and species is unlike any other rhynchonellide known from Australasia or elsewhere. Chathamirhynchia kahuitara is distinguished by its small size, strong ribbing, and well-developed sulciplicate folding, and internally by a large, robust cardinal process and raduliform crura. The shell structure of C. kahuitara is shown to be of typical fine fibrous ‘rhynchonellidine’ type. This brachiopod was probably strongly attached to volcanic rock or shells in a shallow-water, high-energy environment. Implications for the biogeography of brachiopods during the Late Cretaceous are briefly discussed.

A New Species

A new genus and species of Philopotamidae (Philopotaminae),Aymaradellaboliviana, is described from the Bolivian Andes of South America. The new genus differs from other Philopotaminae by the loss of 2A vein in the hind wing and, in the male genitalia, the synscleritous tergum and sternum of segment VIII, and the elongate sclerotized dorsal processes of segment VIII. The first record ofHydrobiosella(Philopotaminae) in the New World is also provided with a new species from the Andes of Ecuador,Hydrobiosellaandina. In addition, a new species of the Neotropical genusChimarrhodella(Chimarrinae),Chimarrhodellachoco, is described from the Choco-Andean region of Ecuador, andChimarrhodellaperuviana(Ross) is recorded from Ecuador for the first time. Lastly,Wormaldiaimbrialis(Philopotaminae), new species, is described, also from the Ecuadorian Choco.

Basal Position

A partial humerus, ulna, and radius compose the type specimen of a new bird, Piksi barbarulna, new genus and species, from the Late Cretaceous (Campanian) Two Medicine Formation of western Montana. This ornithothoracine taxon differs from all other birds in having an enlarged dorsal epicondyle and a reduced ventral condyle on the humerus with corresponding modifications on the articular surface of the ulna. Among modern birds, Piksi is most similar to galliforms, but the paucity of unambiguous characters and its unusual morphology defy placement within any extant "order" and strongly questions any neornithine affinities. Instead, Piksi appears to have a fairly basal position within Ornithothoraces. Several morphologic features of Piksi occur in phylogenetically diverse but morphologically similar birds, such as galliforms, tinamous, and some columbiforms. The new bird comes from an inland, relatively dry paleo-environment. Atypical for a Cretaceous avian record dominated by waterfowl, Piksi appears to represents a heavy-bodied ground bird. Searching of inland depositional environments may yield new and ecologically distinct avian varieties.

AbstractA new genus and species are described within the extinct tribe Haidomyrmecini, and tentatively placed within the subfamily Sphecomyrminae (Hymenoptera: Formicidae).Haidoterminus cippusnew genus and speciesexpands the distribution of the bizarre, exclusively Cretaceous, trap-jawed Haidomyrmecini beyond their previous records in mid-Cretaceous Burmese and French amber, and into Laurentia. The new material from the Grassy Lake, Alberta, Canada collecting locality also provides evidence that these highly specialised, likely arboreal, ants persisted for an additional 20 million years, reaching the Late Cretaceous. Morphological features ofH. cippus, such as the presence of an elongate antennomere II (pedicel), further support the argument that Haidomyrmecini may not actually belong within the subfamily Sphecomyrminae, and may warrant recognition at the subfamily level or inclusion as a highly autapomorphic clade within another subfamily. Despite the introduction of new fossil material, and the clarity of preservation in Canadian amber, the mystery of how Haidomyrmecini fed remains unsolved.

Discovery of a single specimen of brachyuran decapod from the Campanian Millwood Member in southern Manitoba, Canada, permits description of a new genus and species, Cretacocarcinus smithi. Comparison of sternal architecture and general carapace morphology with potentially related taxa documents that the new genus, along with Camarocarcinus Holland and Cvancara, form a new family, Camarocarcinidae, tentatively assigned to the Raninoidea. The Camarocarcinidae are interpreted to have originated in the upper Midcontinental Seaway in the Late Cretaceous, survived the K–T extinction event(s), and dispersed into southern North Dakota, USA; Greenland; and Denmark in the Paleocene.
