Two Inclusions

Chartocerus azizaesp. nov. is described as the first known fossil from the family Signiphoridae, based on two inclusions in the same piece of Eocene Baltic amber (36.7–48.5 million years ago). Implications of the morphology of C. azizae are discussed, indicating that it should be placed in Chartocerus.

A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

Based on material originating from five amber collections of Eocene Baltic amber, Protostomopsis pandema gen. et sp. nov. is described and illustrated using X-ray micro-computed tomography. It is the first formally described extinct species of Cerylonidae, and the first known Palaearctic representative of the subfamily Ostomopsinae. As such, the new species extends the temporal range of the family Cerylonidae by approximately 45 Ma.

AbstractThe fossil record of the family Camerobiidae has been represented by only one species, Neophyllobius succineus Bolland and Magowski, 1990, described from Eocene Baltic amber. These prostigmatan mites are distinguishable by their distinctly long and slender stilt-like legs, and they are associated with aboveground vegetation where they hunt for other small invertebrates. This paper enhances the knowledge of fossil stilt-legged mites. Two new fossil species, N. electrus new species and N. glaesus new species, are described from samples of Baltic amber, and remarks on their morphology and taphonomy are provided. The discovery is complemented with a discussion on morphological singularities (the shape of the prodorsum, the location of setae h1 and h2 in living specimens, and lengths of genual setae), an anomaly of hypertrophied seta (found in the N. glaesus holotype), and some biogeographical issues.UUID: http://zoobank.org/d1602384-ae4f-4f90-b4a1-6cdedd77c9e1

A New Species

AbstractThe family Peradeniidae (Hymenoptera: Proctotrupoidea) is represented by two rare extant species from southeastern Australia (Australian Capital Territory, Victoria, Tasmania). A new species, Peradenia galerita sp. n., is described from Eocene Baltic amber. The fossil species is very similar to the living Perndenia, but has the short metasomatic petiole typical of most Proctotrupoidea. The subfamily classification of Heloridae proposed by Rasnitsyn and the status of Peradeniidae are briefly reviewed. The subfamily Mesohelorinae Rasnitsyn, 1990 is a junior synonym of Protohelorinae Rasnitsyn, 1980 (syn. n.).

AbstractThe tribal classification of Derbidae with respect to Otiocerini is presented and discussed. Key to extant and fossil genera of Otiocerini is provided. New genus and species from Eocene Baltic amber – Lugeilangor elektrokleistis gen. n. et sp. n. of Derbidae tribe Otiocerini Muir is described. It seems to be related to the extant Asian-Pacific genera Paralyricen Muir, 1913, and Flaccia Stål, 1866. It is the second record of the family Derbidae in Eocene Baltic amber inclusions. Palaeobiological and biogeographical significance of the fossil is discussed.

Plesiomorphic Character

Succinoraphidia radioni sp. nov. (Raphidiidae) is described from the late Eocene Rovno amber, Ukraine. The genus also includes two species from contemporaneous Baltic amber, i.e., S. exhibens Aspöck & Aspöck, 2004 and S. baltica (Carpenter, 1957), comb. nov. The venation of Succinoraphidia is analysed. It possesses several plesiomorphic character states at the family level, and the monotypic subfamily Succinoraphidinae represents a basal group within the family or possibly even a potential stem group of Raphidiidae. All diagnostic character states of Succinoraphidia (except the structure of the pterostigma) are found in a few Cretaceous species of the paraphyletic Mesoraphidiidae, but some of these are not found in the extant Raphidiidae.
