General research

  • A study on extant arthropods (mainly insects and spiders) living around the resinous tree Hymenaea verrucosa in the lowland coastal forest of Madagascar and trapped by the resin produced by this tree species, and on their implications for inferring whether amber records the true past biodiversity of the entire forest, is published by Solórzano Kraemer et al. (2018).[1]
  • A study on the early evolution of stem and crown-arthropods as indicated by Ediacaran and Cambrian body and trace fossils is published by Daley et al. (2018).[2]
  • A study on the evolution of ecdysozoan vision, focusing on the evolution of arthropod multi-opsin vision, as indicated by molecular data and data from fossil record, is published by Fleming et al. (2018).[3]
  • Grimaldi et al. (2018) report biological inclusions (fungi, plants, arachnids and insects) in amber from the Paleogene Chickaloon Formation of Alaska, representing the northernmost deposit of fossiliferous amber from the Cenozoic.[4]
  • A mantis lacewing larva found in association with two spiders, attached to one of the anterior walking legs of one of the spiders, is described from the Cretaceous amber from Myanmar by Haug, Müller & Haug (2018), who interpret this finding as evidence of palaeo-parasitism.[5]

Arachnids

Research

  • Review of arachnids known from the Bitterfeld amber (Germany) and a study on their implications for inferring the age of this deposit is published by Dunlop et al. (2018).[6]
  • The first fossil representative of the parasitic mite family Pterygosomatidae, assigned to the genus Pimeliaphilus and similar in morphology to the extant species parasitic on cockroaches, is described from the Cretaceous (Albian) Archingeay amber (France) by Sidorchuk & Khaustov (2018).[7]
  • Fossil mite "Sejus" bdelloides, originally interpret as a member of Mesostigmata, is reinterpreted as a member of Prostigmata referrable to the group Anystina by Dunlop, Walter & Kontschán (2018).[8]
  • A study on the body size of fossil mites is published by Sidorchuk (2018).[9]
  • A hard tick wrapped in spider silk is described from the Cretaceous Myanmar amber by Dunlop et al. (2018).[10]
  • A male specimen of a tick belonging to the genus Ornithodoros and the subgenus (Alectorobius) is described from the Dominican amber by Estrada-Peña & de la Fuente (2018),[11] who also provide illustrated interpretations intended to support the validity of the identity of the fossils reported by de la Fuente (2003).[12]
  • A pseudoscorpion attached to barbules of a contour feather, possibly documenting a phoretic association between pseudoscorpions and Mesozoic birds, is described from the Cretaceous amber from Myanmar by Xing, McKellar & Gao (2018).[13]
  • A study on the phylogenetic history of spiders, based on molecular data and re-examination of the global fossil record, as well as on the ancestral predatory strategies among different groups of spiders and some of the possible drivers of spider diversification during the Early Cretaceous greenhouse, is published by Shao & Li (2018).[14]
  • A study on the burrows produced by wolf spiders belonging to the genus Pavocosa, aiming to identify ichnological signatures which may facilitate identification of wolf spider burrows in the fossil record, is published by Mendoza Belmontes, Melchor & Piacentini (2018).[15]
  • Fossil crevice weaver Misionella didicostae from Dominican amber is transferred to the genus Antilloides by Magalhaes (2018).[16]
  • Evidence of a fossilized cobweb, and a possible case of predation of a theridiid spider on a dolichopodid fly, are reported from the Mexican amber by García-Villafuerte (2018).[17]

  • Description of the morphology of Tetrachela raiblana and a study on its implication for understanding of the homologies of carapace grooves between polychelidans and other decapods is published by Audo, Hyžný & Charbonnier (2018).[38]
  • A large-sized (12.9 mm maximum length) right valve of a marine ostracod is described from the Cretaceous amber from Myanmar by Xing et al. (2018).[39]
  • A study evaluating how sexual selection related to species extinction in fossil cytheroid ostracods is published by Fernandes Martins et al. (2018), who report that species with more pronounced sexual dimorphism had higher estimated extinction rates.[40]
  • An ostracod fauna including four species belonging to the suborder Darwinulocopina is described from the Lower Jurassic (Hettangian) Whitmore Point Member of the Moenave Formation (Arizona and Utah, United States) by Antonietto et al.

Trilobites

Research

  • Frontal auxiliary impressions (muscle scars on the glabella) are described in Mesolenellus hyperboreus from Cambrian Stage 4 strata of North Greenland by Lerosey‐Aubril & Peel (2018), providing new information on the evolution of a pouch‐like digestive organ with powerful extrinsic muscles (i.e. a crop) in trilobites.[115]
  • A study on complete moulted exoskeletons of Estaingia bilobata and Redlichia takooensis from the Cambrian Emu Bay Shale (Australia), and their implications for inferring the course of moulting in trilobites, is published by Drage et al. (2018).[116]
  • A study assessing the morphological differences within and among three populations of Oryctocephalus indicus from the United States, Siberia and China, using a new method of analysing small morphological features, is published by Esteve et al. (2018).[117]
  • A study on early post-embryonic developmental stages of the Cambrian trilobite Ellipsostrenua granulosa is published by Laibl, Cederström & Ahlberg (2018).[118]
  • A study on the ontogeny of the co-occurring shumardiid trilobites Akoldinioidia latus and Koldinioidia choii from the middle Furongian Hwajeol Formation (South Korea) is published by Park (2018).[119]
  • Remains of the digestive system of a specimen of the bathycheilid species Prionocheilus vokovicensis from the Ordovician Šárka Formation (Czech Republic) are described by Fatka & Budil (2018).[120]
  • A study on the postembryonic development of Dalmanitina, based on a large sample of specimens from the Upper Ordovician Prague Basin, is published by Drage, Laibl & Budil (2018).[121]
  • A large and almost complete dorsal exoskeleton of a trilobite referred to the species Dipleura dekayi is described from the Devonian Floresta Formation (Colombia) by Carvalho (2018).[122]
  • A study on the phylogenetic relationships of species belonging to the genus Metacryphaeus is published by Carbonaro et al. (2018), who also perform a palaeobiogeographic analysis for the distribution of the genus.[123]

2018 in insect paleontology

This list of fossil insects described in 2018 is a list of new taxa that were described during the year 2018, as well as other significant discoveries and events related to insect paleontology that are scheduled to occur in the year 2018.

Chimerarachne

Chimerarachne is a genus of extinct arachnids containing a single species Chimerarachne yingi. Fossils of Chimerarachne were discovered in Burmese amber from Myanmar which dates to the mid-Cretaceous, about 100 million years ago. Its classification is disputed, either belonging to Uraraneida a group otherwise known from the Devonian to Permian, or a separate clade closer to spiders. Since the earliest spider fossils are from the Carboniferous, either answer results in an at least a 170 myr ghost lineage with no fossil record, making it a Lazarus taxon. The size of the animal is quite small, being only 2.5 mm in body length, with the tail being about 3mm in length. These fossils resemble spiders in having two of their key defining features: spinnerets for spinning silk, and a modified male organ on the pedipalp for transferring sperm. At the same time they retain a whip-like tail, rather like that of a whip scorpion and uraraneids. Chimerarachne is not ancestral to spiders, being much younger than the oldest spiders which are known from the Carboniferous, but it appears to be a late survivor of an extinct group which was probably very close to the origins of spiders. It suggests that there used to be spider-like animals with tails which lived alongside true spiders for at least 200 million years.

Cretapsyche

Cretapsyche is an extinct genus of caddisflies in the extinct family Dysoneuridae. It is from the Late Cretaceous (Cenomanian) and specimens are from Burmese amber.

The genus includes the three species C. circula, C. elegans and C. insueta.
