The Rich

The rich decapod assemblage from the late Eocene of San Feliciano hill (Orgiano, Monti Berici, Vicenza, NE Italy) was partially recorded by De Angeli and Garassino (2002, 2014). Herein, two new crabs, Bericirinia bretoni n. gen., n. sp. (Epialtidae MacLeay, 1838) and Orgianocarcinus bericus n. gen., n. sp. (Dairidae Ng and Rodriguez, 1986) are reported from San Feliciano Hill, located in Monti Berici, Orgiano. Moreover, two well-preserved specimens assigned to Actaeites lobatus Müller and Collins, 1991 (Xanthoidea MacLeay, 1838, incertae sedis) allowed to add some morphological characters to the original description of the holotype, lacking the fronto-orbital margin.

Fossil Genus

Following an exhaustive review of published molecular data and morphological characters, we propose a new generic classification for the Cyprinodontiform family Aphaniidae. The generic concept applied is based on monophyly, reasonable compactness, and morphological diagnoses. The proposed genera are monophyletic and compact groups that can be diagnosed by a combination of morphological characters. All species in Aphaniidae are morphologically homogeneous and have similar scale patterns, fin positions, and meristic characters. However, only a handful of morphological characters, including colour patterns, permit identification. We propose separation of Aphaniidae into eight monophyletic genera: Anatolichthys, Aphaniops, Aphanius, Kosswigichthys, Paraphanius, and Tellia, in addition to the new genera Esmaeilius and Apricaphanius, which are described for the species of the A. sophiae and A. iberus species groups, respectively. The original description of Aphanius hormuzensis does not fulfil the criteria of the International Commission on Zoological Nomenclature, therefore this taxon is re-described as A. teimorii. Esmaeilius arakensis, E. kavirensis, E. mesopotamicus, and E. pluristriatus are treated as synonyms of E. sophiae. Esmaeilius farsicus is a junior synonym of E. persicus (Jenkins, 1910). The fossil genus Brachylebias is considered as incertae sedis since it lacks diagnostic characters which would permit it to be assigned to any of the extant genera recognised in this study.

Stratigraphic Range

The rich decapod community from the late Eocene (Priabonian) of San Feliciano (Orgiano, Vicenza, northeastern Italy) was partially described by De Angeli &amp; Garassino (2002). Anomurans and brachyurans are the main component of this community, whereas the macrurans are very scarce. The studied specimen is the first report of macrurans from this locality after twenty years of field research. Similar carapace morphological characters allow the studied specimen to be assigned to the extant <em>Palinurellus</em> von Martens, 1878, and differences with the two species of <em>Palinurellus</em> allow erection of a new species <em>P. bericus</em> n. sp. The report of <em>Palinurellus</em> in the fossil record is significant because it expands the stratigraphic range of this genus back to the late Eocene. It also represents the second report of the Palinuridae from the Eocene of Vicenza.

Group Relationships

The monotypic genus Chlamydolecanium Goux (Hemiptera: Coccoidea: Coccidae) is known only from the original collection in Corsica. The original description does not allow definite placement in any of the subfamilies in the Coccidae. Although it had been suggested that it belonged to the Cardiococcinae, no other members of this subfamily were geographically close. The adult female and 1 st -instar nymph of the type species, Chlamydolecanium conchioides Goux are here redescribed. A parsimony analysis was undertaken based on 56 morphological characters of the adult females in 29 taxa (24 genera considered to belong to the Cardiococcinae, plus Parafairmaria bipartita (Signoret), an incertae sedis monospecific genus possibly close to Cardiococcinae, plus the recently described Kenima galilit Ben-Dov plus two other soft scale genera as outgroups (Coccus hesperidum L. and Paralecanium frenchii (Maskell)). This analysis confirmed the placement of the genus Chlamydolecanium within the Cardiococcinae clade, although its sister-group relationships remain unresolved. Its geographic distribution and taxonomic relationships are discussed.

Ramalina sekika Asahina is reported for the first time from Russia from Sakhalin. It refers to the number of rare and poorly investigated species of the genus. Until now it was considered to be endemic to northeastern China. The original description and the location in the Far East are given, as well as the data on anatomical and morphological study of the Russian specimen. The differences in the anatomical structure of its thallus are discussed. A comparison of anatomical and morphological characters of R. sekika, R. pollinaria (Westr.) Ach. (European material), R. yasudae Räsänen has been made; the author considers them as independent species.

In 1958 Deichmann synonymized Holothuria inornata Semper, 1868 with Holothuria kefersteinii (Selenka, 1867). This nomenclature has been adopted until now. However, some specimens recently collected from the Mexican Pacific matched the original description of H. inornata Semper (1868) whereas others matched the original description by Selenka (1867). A morphological, molecular and ecological study of the specimens was conducted to confirm the identification of these specimens. The morphological characters of our specimens were compared with those contained in the original descriptions and figures of the types of both species. Besides the different color pattern of live specimens of both species, the main differences found are the presence of straight distally perforated rods in the dorsal papillae, and the presence of Holothuriophilus trapeziformis Nauck, 1880 in the cloaca of H. inornata, versus the absence of these kind of rods in the dorsal papillae, and the absence of symbionts in the cloaca in H. kefersteinii. The species identified by Deichmann (1958) as H. kefersteinii is, in fact H. inornata. Both species might have been confused because the morphology of preserved specimens is very similar and the presence of the straight rods in papillae might have been overlooked during identification. A more thorough review of the ossicles from the specimens, together with the comparison of ossicles from the type specimens, has allowed the resurrection of long-forgotten species, H. inornata

Background The rich rodent assemblages from the Eocene–Oligocene deposits of the Jebel Qatrani Formation (Fayum Depression, Egypt) have important implications for our understanding of the origin and paleobiogeography of Hystricognathi, a diverse clade that is now represented by the Afro-Asiatic Hystricidae, New World Caviomorpha, and African Phiomorpha. Methods Here we present previously undescribed material of the enigmatic hystricognath clade Phiocricetomyinae, from two stratigraphic levels in the lower sequence of the Jebel Qatrani Formation—a new genus and species (Qatranimys safroutus) from the latest Eocene Locality 41 (~34 Ma, the oldest and most productive quarry in the formation) and additional material of Talahphiomys lavocati from that species’ type locality, early Oligocene Quarry E (~31–33.2 Ma). Results The multiple specimens of Qatranimys safroutus from L-41 document almost the entire lower and upper dentition, as well as mandibular fragments and the first cranial remains known for a derived phiocricetomyine. Specimens from Quarry E allow us to expand comparisons with specimens from Libya (late Eocene of Dur at-Talah and early Oligocene of Zallah Oasis) that have been placed in T. lavocati, and we show that the Dur at-Talah and Zallah specimens do not pertain to this species. These observations leave the Fayum Quarry E as the only locality where T. lavocati occurs.

Autolytinae is revised based on available types, and newly collected specimens. Out of 170 nominal species, 18 are considered as incertae sedis, 43 are regarded as junior synonyms, and 25 are referred to as nomina dubia. The relationships of Autolytinae is assessed from 51 morphological characters and 211 states for 76 ingroup-taxa, and 460 molecular characters from mitochondrial 16S rDNA and nuclear 18S rDNA for 31 ingroup-taxa; outgroups include 12 non-autolytine syllid polychaetes. Two analyses are provided, one including morphological data only, and one with combined morphological and molecular data sets. The resulting strict consensus tree from the combined data is chosen for a reclassification. Three main clades are identified: Procerini trib. n., Autolytini Grube, 1850, and Epigamia gen. n. Proceraea Ehlers, 1864 and Myrianida Milne Edwards, 1845 are referred to as nomen protectum, while Scolopendra Slabber, 1781, Podonereis Blainville, 1818, Amytis Savigny, 1822, Polynice Savigny, 1822, and Nereisyllis Blainville, 1828 are considered

Molecular Identity

Anopheles (Nyssorhynchus) oswaldoi (Peryassú, 1922) comprises a species complex in South America. To fully characterize other taxa within the Oswaldoi Complex, it is essential to fix the identity of the nominotypical member. Given that the no type was designated in the original description, a lectotype is formally designated from the remaining syntypes in the Museu Nacional do Rio de Janeiro. These and other recently collected specimens from the type locality (Espírito Santo, Brazil) and the State of São Paulo, Brazil were used to redescribe the species using morphological characters of the adult female, male and male genitalia, and the fourth-instar larva and pupa. The larva, pupa, and male genitalia are illustrated. Diagnostic morphological characters of the adult female and male genitalia are provided to distinguish An. oswaldoi s.s. from the morphologically similar An. konderi, An. galvaoi, and An. ininii. DNA sequence data from the second nuclear internal transcribed spacer region (ITS2) are included to fix the molecular identity of An. oswaldoi s.s.
