Abstract:
This paper reports a new species Anthoxyela orientalis sp. nov. referred to the genus Anthoxyela Rasnitsyn, 1977 of the subfamily Macroxyelinae (Symphyta, Xyelidae). This fossil was collected from the Yixian Formation of western Liaoning, China. Based on characters of this specimen, the diagnosis of the genus Anthoxyela is revised.

Abstract:
An inventory of the Myriapoda (Diplopoda, Chilopoda, Symphyla) from Cretaceous Burmese amber, Myanmar, is presented, including the oldest and/or first fossil record for numerous orders. For millipedes (Diplopoda) 527 records, including 460 new specimens determined by us, belonging to 13 of 16 recent orders are listed: Polyxenida, Glomeri­desmida, Glomerida, Siphonophorida, Polyzoniida, Platydesmida, Siphoniulida, Chordeumatida, Polydesmida, Stemmiulida, Callipodida, Spirostreptida and Spirobolida. For centipedes, 33 records for 4 of the 5 recent orders are listed: Scutigero­morpha, Lithobiomorpha, Scolopendromorpha and Geophilomorpha. For Symphyla, three records for both families, Scutigerellidae and Scolopendrellidae, are listed. The majority of Diplopoda records (30.5%) are Polydesmida. The record of the Polyzoniida includes first instar octopod juveniles. The checklist includes the first fossil representatives known of the Platydesmida, as well as the oldest known fossils of the Polyxenida, Glomeridesmida, Glomerida, Siphono­phorida, Polyzoniida, Siphoniulida, Spirostreptida, as well as both Symphyla families. Misidentifications by Zhang (2017) are corrected; while most Chilopoda in that list are correct, almost all Diplopoda are misidentified.

Abstract:
We critically re-examine nine of the ten fossil specimens currently assigned to Hepialidae. Three fossils with impressions of wing veins and scales placed in the fossil genus Prohepialus Piton, 1940, and two mummified larvae that show apomorphic characters, have features that support placement in Hepialidae. The other four fossils that we evaluate, Prohepialus incertus Piton, 1940; Oiophassus nycterus Zhang, 1989; Protohepialus comstocki Pierce, 1945; and a fossil scale, lack definitive hepialid characters. One of these, Prohepialus incertus Piton, 1940, appears to represent a symphytan (Hymenoptera), and is excluded from Lepidoptera. The fossilized wings placed in Prohepialus by Jarzembowski display numerous features that indicate a proximate phylogenetic relationship to extant members of the hepialid genus Sthenopis Packard and related genera.

Abstract:
The stephanid wasps are of great phylogenetic and biological significance among parasitic Hymenoptera, itself one of the major radiations of insects and of critical ecological and agricultural importance. The family, the only one of its superfamily (e.g., Gauld and Bolton, 1988; Goulet and Huber, 1993: although Rasnitsyn, 1988, 2000 includes the traditional Trigonalyoidea, Megalyroidea, Ceraphronoidea, and some extinct lineages in the Stephanoidea), is hypothesized by some authors to be basal within the diverse parasitoid lineage Apocrita (Rasnitsyn, 1975, 2000; Königsmann, 1978; Rohdendorf and Rasnitsyn, 1980; Whitfield, 1992, 1998; Vilhelmsen, 1996, 2001). Such a phylogenetic placement makes the stephanids an interesting link between the principally xylophagous wood wasps (i.e., the paraphyletic suborder Symphyta), the sole parasitic symphytan family Orussidae, and the remainder of the Apocrita (Orussidae + Apocrita = Euhymenoptera). Thus, stephanids may represent one of the earliest families of parasitoid wasps exhibiting the characteristic “wasp waist,” allowing for more control and flexibility during oviposition. Tantalizingly, the stephanids are morphologically similar to orussids in that both exhibit a characteristic series of tubercles on the head (presumably an adaptation for allowing them to move through burrows in wood after eclosion). These similarities, however, may be convergent adaptations of parasitizing wood-boring insects (a plesiomorphic biological trait across the Apocrita) and stephanids may belong to a clade of evaniomorphous wasps, albeit still relatively basal within that lineage (e.g., Rasnitsyn, 1988; Ronquist et al., 1999). In either case, Stephanidae figure prominently in cladistic studies of the Hymenoptera and are of presumably ancient origin based on their phylogenetic position (e.g., Rasnitsyn, 2000). Fossils of the family, however, are rare and until now have been restricted to Tertiary deposits.

Abstract:
AbstractData on diversity are fundamental to our understanding of both natural and disturbed ecosystems. Yet, despite their real and potential importance, knowledge of the diversity of non-pterygote soil arthropods in Canada still is very incomplete. This is illustrated with information on diversity from nine non-pterygote arthropod taxa: Tardigrada, Chilopoda, Diplopoda, Symphyla, Pauropoda, Protura, Collembola, Pseudoscorpionida, and Oribatida, and faunal lists are given for six of these taxa. Although valuable family and generic keys have been published recently, few monographic works or user-friendly keys to species are available. Autecological information essential to explaining the functional role of soil arthropods remains inadequate. Fortunately, the needs of other disciplines and issues are causing a change. For example, current ecological research recognizes that the roles of soil arthropods in decomposition, nutrient cycling, and soil formation are more complex than previously supposed, palaeoecologists require new or corroborating data to interpret their fossil assemblages, and issues such as agroecosystem management, environmental indicators, and global change require a more thorough knowledge of soil communities. Researchers in these areas face poor data on diversity based on inadequate systematics, which limit their understanding of the composition and organisation of soil arthropod communities. This inadequacy presents both a challenge and an opportunity to soil arthropod systematists and ecologists.

Abstract:
Cette étude a eu pour objectif d'éclairer la question de la variabilité morphologique et métrique de la symphyse mandibulaire et des structures mentonières dans les populations actuelles et chez les Hommes fossiles à partir du genre Homo. Une nouvelle approche morphologique et de nouvelles mesures ont été réalisées au sein de ce travail, dans le but d'améliorer la diagnose des caractères morphométriques de la symphyse. Une nouvelle méthode informatisée, the GIMP, de calcul des surfaces symphysaires a été mis au point. Dans la plupart des populations actuelles, la symphyse mandibulaire a gardé quelques caractères archaïques au niveau des faces antérieure et postérieure. L'étude morphométrique comparée des structures symphysaires dans les échantillons actuels a mis en évidence une variabilité importante interpopulationnelle et intrapopulationnelle. Chez les fossiles, la symphyse, du point de vue morphologique et métrique, a évolué au cours de la lignée humaine. Cette évolution a été marquée par l'apparition des caractères modernes. De plus, nous avons pu prouver que l'apparition du menton est une conséquence de plusieurs phénomènes évolutifs et consécutifs. De plus, nous avons mis en évidence que l'acquisition des caractères modernes est plus rapide pour la face antérieure que pour la face postérieure de la symphyse.
