A new species of Dynomene from the Priabonian (Upper Eocene) of the central Pyrenees in Aragón (Spain) is described as the first record of the genus from the Iberian Peninsula. The new species reveals close similarities to other dromioid species described from the Priabonian of Hungary. The panopeid Eoacantholobulus oscensis Ossó & Domínguez, 2017, from the same locality, is reviewed and transferred to the genus Sculptoplax, after comparisons with specimens of Sculptoplax rigida Müller & Collins, 1991 from the Priabonian of Italy. The present note again provides evi- dence of the close relationship between the Late Eocene decapod crustacean faunas of the western-most Tethys and the Pyrenean basins.

The Iberian Peninsula is part of the South European Atlantic Shelf within the Lusitanian ecoregion. Given the characteristics of this region, a great invertebrate biodiversity is expected. Nevertheless, no literature records of Polycladida are known for the Cantabrian Sea. Here, we report the presence of six polyclad species, including one new species.Notoplana vitrea, considered endemic to the Mediterranean Sea, was found in the Cantabrian Sea, demonstrating its presence in Atlantic waters. This species was previously reported for these waters on two natural history photographic websites: the importance of searching, indexing and disseminating this type of record for the scientific community is discussed.Discocelis tigrinais reported for the first time for the Cantabrian Sea, and is the northernmost record to date. In this paper,Pleioplana atomatais reported for the second time for the Iberian Peninsula, yet is the first record for the Cantabrian Sea. Although a literature record ofLeptoplana tremellarisfor the Iberian Peninsula exists, it is considered a misidentification ofL. mediterranea; therefore, this work provides the first record ofL. tremellarisfor the Iberian Peninsula. The cosmopolitan speciesCycloporus papillosusis also reported for the Cantabrian Sea. A new species,Imogine fafaisp. nov., is described and taxonomically compared with other species of the genus.

A New Species

A new species of the fossil ant genus Drymomyrmex Wheeler, 1915, D. rasnitsyni sp. nov., is described from the late Eocene Rovno amber (Ukraine). This is the first find of a worker of this genus and the first record of Drymomyrmex in the Rovno amber. Based on the analysis of the morphological features of gynes and worker it is proposed to attribute Drymomyrmex to the tribe Plagiolepidini Forel, 1886.

A new species of the late Mesozoic–Cenozoic family Ringiculidae (Ringicula (Ringicula) cockburnensis n. sp.) is described from basal glauconitic beds of late Eocene age of Cockburn Island, Antarctica, and is the first reported occurrence of the family Ringiculidae from the continent of Antarctica. Ringicula (R.) cockburnensis n. sp. most closely resembles R. castigata from the middle Oligocene Duntroonian Stage of New Zealand and provides further support for the strong provinciality (Weddellian Province) that existed along the southern margin of the Pacific during the Late Cretaceous and early Tertiary.

<em>Diplacodes lefebvrii</em> (Rambur, 1842) is a libellulid dragonfly, which is common and widespread in Africa and across the Indian Ocean. While this species is fairly common in the south and east of the Mediterranean, its European range is confined to Cyprus, the island of Rhodes and the south of the Iberian Peninsula. Here we report the first record of <em>D. lefebvrii </em>for Italy, which was captured near Cagliari (Sardinia) on 11.IX.2013. In October 2014, a population of the same species was observed at a small wetland on the island “Isola di San Pietro” (Sardinia). Here the observed sex ratio of <em>D. lefebvrii</em> was strongly biased in favour of females and only a single male was observed.

A New Species

A new species of Limnophilinae (Diptera: Limoniidae), Dicranophragma (Brachylimnophila) relictum Mederos sp. nov., is described. This is the third species of this genus recorded from the Iberian Peninsula. This new species was discovered in a cave in the Sant Llorenç del Munt i Serra de l’Obac Natural Park, Barcelona Province (Catalonia) and it is the first record of a species of this genus from a hypogeous environment. The absence of suitable ecological conditions for the survival of this new species, particularly in the vicinity of the cave, suggests that this population of D. relictum Mederos sp. nov. is isolated. Dicranophragma relictum Mederos sp. nov. is characterized by the following features: a general grey-to-greenish-grey coloration on its thorax and a dark-grey abdomen; wings more than four times longer than wide; pale-brown-to-yellowish tinted wings, with brown veins and a well-marked stigma; in the male genitalia the upper part of the aedeagus is acute when viewed laterally and is longer than the lower part. A key is provided for separating the three species of Dicranophragma known to be present in the Iberian Peninsula.

A New Species

We describe a new species of homolid crab from the Ypresian (early Eocene) Roda Formation of Huesca province (Aragon, Spain). In spite of the fragmentary condition of the sole specimen, some preserved frontal elements, and in particular the complete left cheliped, allow inclusion it within the genus Paromola Wood-Mason in Wood-Mason and Alcock, 1891, based on morphological similarities with the extant species of this genus. Direct comparison with specimens of the extant Paromola cuvieri (Risso, 1815) confirms this systematic assignment. Paromola bretoni n. sp. is the first homolid reported in the Cenozoic of the Iberian Peninsula, and expands the rich decapod fossil record of the Eocene basins of southern Pyrenees.

Decapod crustacean specimens from the middle Eocene San Juan Formation in central Chiapas represent the first record of Eocene decapods in southern México. New taxa include: Dardanus mexicanus new species (Diogenidae), Lophoranina cristaspina new species, Notopus minutus new species (Raninidae); Verrucoides stenohedra new genus and new species (Xanthidae); Stoaplax nandachare new genus and new species (Goneplacidae); and Viapinnixa alvarezi new species (Pinnotheridae). Verrucoides verrucoides new genus and new combination from the Paleocene of Greenland represents a new combination. In addition, the fauna includes Callianassa sensu lato sp., Laeviranina sp., Calappilia cf. C. hondoensis Rathbun, 1930, Eriosachila sp., and indeterminate calappid and xanthoid taxa. This assemblage bears close relationship with coeval faunas in the Tethyan region of southern Europe and southern North America and with Paleocene faunas of Greenland, strengthening the evidence for previously described patterns of dispersal within the Decapoda.
