Abstract Molecular dating estimates the appearance of the family Oedemeridae in the Early Cretaceous. Several fossil representatives are known from Spanish (105 Ma) and Myanmar (99 Ma) ambers. The family also has been mentioned by several authors to occur in Eocene Baltic amber, but virtually no species was described until now. Here, we provide a description of the first fossil oedemerid species from Eocene Baltic amber, which is classified within subfamily Oedemerinae, in the extant genus Oedemera Olivier as Oedemera (s. str.) girulskii n. sp. The presence of appendiculate pretarsal claws and relatively large eyes separate the new species from its extant congeners. UUID: http://zoobank.org/24b0b919-8684-4908-b002-9521b071dcc8.

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.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

Extinct Genus

The taxonomy of the Polycentropodidae is discussed, and the family is divided into 4 newly defined diagnostic genus clusters based primarily on wing characters and number of spurs on the legs. The diagnostic genus clusters are the Neureclipsis diagnostic genus cluster with Neureclipsis McLachlan and Neucentropus Martynov; the Polycentropus diagnostic genus cluster with Polycentropus Curtis, Plectrocnemia Stephens, Holocentropus McLachlan, and Polyplectropus Ulmer; the Cyrnus diagnostic genus cluster with Nyctiophylax Brauer, Cyrnus Stephens, Cyrnopsis Martynov, Cyrnellus Banks, and Adectophylax Neboiss; and the Cyrnodes diagnostic genus cluster with Cyrnodes Ulmer, Cernotina Ross, and Pahamunaya Schmid. The extinct genus Archaeoneureclipsis Ulmer is synonymised with Neureclipsis McLachlan; the extant genus Tasmanoplegas Neboiss is synonymised with Plectrocnemia Stephens; the extant genus Eodipseudopsis Marlier is synonymised with Polyplectropus Ulmer; and the extinct genus Nyctiophylacodes Ulmer is synonymized with Nyctiophylax Brauer. The following 8 new species are described in Plectrocnemia: P. martynovi (Myanmar), P. ambaita (Myanmar), P. kachin (Myanmar), P. taungyia (Myanmar), P. dalat (Vietnam), P. kamba (Myanmar), P. malaisei (Myanmar), and P. thai (Vietnam). The following 11 new species are described in Polyplectropus: P. daimong (Vietnam), P. dinhdan (Vietnam), P. giandi (Vietnam), P. jalan (Malaysia), P. pairavatika (Malaysia), P. vanuatu (Vanuatu), P. coronivia (Fiji), P. palma (Fiji), P. vanda (Fiji), P. vanua (Fiji), and P. wainimbuk (Fiji). The following 2 new species are described in the subgenus Nyctiophylax (Nyctiophylax): N. (N.) hotay (Vietnam) and N. (N.) catunujah (Myanmar). The following 7 new species are described in the subgenus Nyctiophylax (Paranyctiophylax): N. (P.) anosib (Madagascar), N. (P.) buoc (Vietnam), N. (P.) dhauli (India), N. (P.) kilah (Madagascar), N. (P.) lancelot (Malaysia), N. (P.) mintin (Vietnam and Laos), N. (P.) nepenthes (Malaysia). Cyrnopsis tangaron is described from Indonesia (Borneo). And the following 3 new species in Pahamunaya are described: P. espelandae (Brunei), P. wamana (Malaysia) and P. khoii (Vietnam). In addition, new records for 20 species are given.

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

One new genus and three new species of Lygistorrhinidae in early Eocene Cambay amber from India are described, which significantly increases our knowledge about this group in the Eocene.Lygistorrhina indican. sp. is the oldest fossil known from this extant genus.Indorrhina sahniin. gen. et sp. shows morphological similarities to each of the two extant generaLygistorrhinaandAsiorrhina.Palaeognoriste orientaleis the third species known from a group that has only been recorded from Eocene Baltic amber before. The latter finding reveals faunal links between Cambay amber and the probably slightly younger Baltic amber, adding further evidence that faunal exchange between Europe/Asia and India took place before the formation of Cambay amber.

Two New Species

The dipteran family Bolitophilidae, with the single extant genus Bolitophila, is a small family of mycophagous flies. In marked contrast to related families such as Sciaridae and Mycetophilidae, the family has a poor fossil record with no definite species assigned to the genus. In addition, the position of the extinct Cretaceous subfamily Mangasinae Kovalev, 1986 (described in Bolitophillidae) has been controversial and it has been suggested that species in this clade may belong to other sciaroid families. This situation is made worse by misplacement of the type specimen. We herein describe two new species of Bolitophila, Bolitophila warreni sp. nov. from the 46-million-year-old Kishenehn Formation in Montana, USA and Bolitophila rohdendorfi sp. nov. from Baltic amber. Bolitophila pulveris Lewis, 1969 is reassigned to Sciaroidea incertae sedis. The subfamily Mangasinae is reviewed and its position within the Bolitophilidae confirmed. Two new species of Mangas, M. kovalevi sp. nov. and M. brevisubcosta sp. nov., both from the Lower Cretaceous of Khasurty in Western Transbaikalia, are described.

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.
