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).

Twenty-four nearly complete carapace samples were collected at three different localities of the Maastrichtian (Late Cretaceous) Cárdenas Formation in San Luis Potosí, east-central Mexico. The material has been assigned to five families: the Callianassidae, Dakoticancridae, Carcineretidae, ?Majidae, and Retroplumidae. Two genera of callianassid shrimp are described, Cheramus for the first time in the fossil record. Dakoticancer australis Rathbun is reported as the most abundant crustacean element; one new genus and species of carcineretid crab, Branchiocarcinus cornatus, is erected, and a single, fragmentary specimen is questionably referred to the Majidae. The three localities reflect paleoenvironmental differences, exhibited by different lithologies, within marginal marine, lagoon environments. The record of dakoticancrid crabs in the Cardenas Formation extends the paleobiogeographic range of the family and the genus Dakoticancer. Carcineretid crabs, although not abundant, seem to have been a persistent element of crustacean assemblages in clastic environments during the Late Cretaceous of the ancestral Gulf Coast of Mexico.

Stratigraphic Range

Two new cirroidean gastropod genera, Alaskiella (family Porcelliidae) and Alaskacirrus (family Cirridae), from the Emsian (late Early Devonian) of west-central Alaska (Medfra B-4 quadrangle) are described. The shell of Alaskiella medfraensis new genus and species exhibits inclined heterostrophic coiling. This shell character is known among other members of the subclass Archaeogastropoda, but is recorded for the first time within members of the superfamily Cirroidea. Inclined heterostrophic coiling of the shell was probably developed independently in several different groups of the subclass Archaeogastropoda. The new genus Alaskacirrus, represented by Alaskacirrus bandeli new species, is the oldest and only known Paleozoic member of the family Cirridae. This suggests that the family Cirridae was separated from the family Porcelliidae since at least Early Devonian time and that it most probably developed from the subfamily Agnesiinae of the family Porcelliidae. Thus, the stratigraphic range of the family Cirridae is at least from Lower Devonian to Cretaceous, an interval of about 350 million years.

Herein we describe a new fossil from the Araripe Basin, <italic>Cratoavis cearensis</italic> nov. gen et sp., composed of an articulated skeleton with feathers attached to the wings and surrounding the body. The present discovery considerably extends the temporal record of the Enantiornithes birds at South America to the Early Cretaceous.

Evolutionary Stasis

AbstractThe mid-Cretaceous weevil fossils from the Orapa Diamond Mine in Botswana are studied, and a new genus and species, Orapaeus cretaceus Kuschel & Oberprieler, is described. This fossil genus is placed in the tribe Eurhynchini of Brentidae and compared with the two extant genera of the tribe. With the discovery of Orapaeus, the family Brentidae can, for the first time, be traced back to Cretaceous times, and there is evidence that the brentid subfamilies and perhaps also the tribes were already differentiated by the Middle Cretaceous. By contrast, the modern families of angiosperm plants were evidently not yet established by then. In consideration of the palaeoflora of Orapa, it is concluded that the environment probably was tropical and the area well vegetated, but that no clues are present as to the likely hostplant(s) of Orapaeus. The differences between Orapaeus and the extant Eurhynchini suggest that the fossil insect fauna of Orapa is generally assignable to extinct forms, and these differences do not support a hypothesis of prolonged evolutionary stasis.

A diminutive paguroid shield from Lower Eocene strata in the Lessini Mountains (northern Italy), recorded several years ago as Paguristes sp. (sensu Beschin et al. 2016), is here transferred to the family Calcinidae Fraaije, Van Bakel & Jagt , 2017, on the basis of the presence of an intra- gastric Y-linea. The new genus and species, Joecalcinus bolcensis, erected here constitute the second known extinct member of this family. We postulate that calcinids derived from the Annuntidiogenidae Fraaije, 2014 during the Late Cretaceous.

The family Sphaerocorynidae includes two valid genera and five species, most of which have a confusing taxonomic history. Here, a new genus and species, Astrocoryne cabela, gen. et sp. nov., is described from the Maldives and the Red Sea, based on both morphological and molecular evidence. Astrocoryne cabela has an apomorphy represented by the type of tentacles, here named ‘dicapitate’, and consisting of capitate tentacles with a proximal capitulum-like cluster of nematocysts. Molecular analyses confirmed the monophyly of this species, as well as its belonging to the Sphaerocorynidae, together with Sphaerocoryne spp. and Heterocoryne caribbensis Wedler &amp; Larson, 1986, for which we present molecular data for the first time. Moreover, the high divergence of A. cabela from other species of the family justifies the establishment of a new genus. Interestingly, specimens from the Maldives and the Red Sea showed marked morphological variation in the polyp stage, although only a slight genetic divergence was detected. This study highlights that a comprehensive morpho-molecular assessment of Sphaerocorynidae is strongly needed in order to clarify the taxonomic issues and the diversity of this taxon.

AbstractThe definition of the family Evaniidae is revised and Cretevaniidae are synonymised with Evaniidae based on evidence derived from recently described Mesozoic taxa and a new genus and species, Lebanevania azari, described here from Lebanese amber. A fore leg with a long trochanter and a 12-segmented antenna are autapomorphies of the new genus. A large, high and wide head and a high and short mesosoma are derived characters shared with other Evaniidae. The new genus also has complete fore wing venation and lacks a tubular petiole, which are ground plan features of the Evanioidea. A cladistic analysis of fossil and extant members of the superfamily Evanioidea and notes on fossil taxa are presented.

Nearctic Region

AbstractThe 11 genera of Nearctic Braconini are keyed: two of them, Myosoma Brullé with a wide pantropical range and Alienoclypeus Shenefelt, new genus, are found chiefly in the Chihuahuan desert and shrub fauna of northern Mexico and the southwestern U.S.A. and are recorded as Nearctic for the first time. Four new species are described in Myosoma: eumystax, impexum, longius, and durango. R. D. Shenefelt describes a new genus and species, Alienoclypeus insolitus. The genus Atanycolimorpha Viereck, 1913 is synonymized with Ipobracon Thomson, 1892. The genus Coeloides is revised for the Nearctic Region; 12 species are described and illustrated. Five of these are new: mexicanus, durangensis, sympitys, tsugatorus, and sonora. One species, C. rossicus (Kokujev), is Holarctic, a new subspecies, betulae, is described from Canada. The following are new synonyms: C. rufovariegatus (Provancher) = (dendroctoni Cushman), C. vancouverensis (Dalla Torre) = (brunneri Viereck), C. crocator (Kirby) = (promontorii Dalla Torre).
