Fossil Genus

A new fossil genus of the family Hybotidae is described, based on male and female specimens. The new genus is monotypic: Syneproctus caridadi gen. et sp. nov. It belongs to the subfamily Hybotinae and shares some characters with the extant genera Syneches Walker, 1852, Stenoproctus Loew, 1858 and Chillcottomyia Saigusa, 1986; however, the differences, principally in the wing venation (shortened cua cell, horizontal m-cu crossvein) and sclerotized mouthparts, support the description of a new genus. This is the first description of a new taxon of the subfamily Hybotinae from specimens preserved in Dominican amber.

A new fossil genus of Bibionidae (Diptera: Bibionomorpha), Burmahesperinus gen. nov., from the mid-Cretaceous Burmese amber, is described and illustrated (type species Burmahesperinus antennatus sp. nov., the other two species included are B. conicus sp. nov. and B. pedicellatus sp. nov.). The new genus is tentatively placed in a new subfamily, Burmahesperininae subfam. nov. of the family Bibionidae. Its possible phylogenetic position is briefly discussed. The new genus, as well as the subfamily, possesses the wing venation similar to the recent genus Hesperinus Walker, 1848, in combination with Brachycera-like modification of both the male and female antenna and the overall habitus typical of fungus gnats (Sciaroidea).

The record of the fossil representatives of the family Juliidae is updated. The new genus Candinia is proposed, in the subfamily Juliinae, for two fossil species somewhat intermediate between Julia and Berthelinia. The new species Candinia pliocaenica is recorded from the lower Pliocene shallow marine deposits near Siena (Tuscany, Italy). This is the first record of Sacoglossa in the Mediterranean Basin. Based on the very specialized life habits of the Juliidae, it is suggested that subtropical Caulerpa algal prairies inhabited the Mediterranean during the early Pliocene, likely becoming extinct in this basin because of the mid-Pliocene climatic deterioration.

A new stonefly genus and species of the family Leuctridae, Euroleuctra gillesi gen. et sp. nov., is described and illustrated based on a well-preserved male specimen in the Eocene Baltic amber from Poland. The new genus is a new member of Leuctridae, exhibiting typical leuctrid diagnostic characters of the terminalia and wing venation. The new genus is also compared with related extant and extinct taxa.

A new genus and species, Patagosmilus goini, of the family Thylacosmilidae (Mammalia, Metatheria, Sparassodonta) is described here. The new taxon is based on a single specimen collected from the west margin of the Río Chico, in Río Negro Province, Argentina, from the middle Miocene Colloncuran SALMA. Until now, two formally recognized species were encompassed in the family Thylacosmilidae: Thylacosmilus atrox, from the late Miocene-late Pliocene Huayquerian to Chapadmalalan SALMAof Argentina and probably Uruguay; and Anachlysictis gracilis, from the middle Miocene Laventan SALMA of Colombia. Recognition of the Patagonian taxon, Patagosmilus, provides new anatomical data, likely to be included in future phylogenetic analyses. The overall morphology of Patagosmilus suggests that it has a more generalized anatomy than Thylacosmilus. The dental morphology suggests the new Patagonian taxon was probably closer to Thylacosmilus than Anachlysictis. Saber-tooth thylacosmilids have several autapomorphic features in the skull that differentiate them from other sparassodonts, including the delayed replacement or non-replacement of the deciduous last premolar.

AbstractLebanoraphidia nana gen. et sp.n. is described from the Lower Cretaceous amber of Lebanon and represents the smallest known Raphidioptera. The new taxon is quite similar in its minute size, large compound eyes and wing venation to Nanoraphidia electroburmica (Mesoraphidiidae) from the Lower Cretaceous amber of Myanmar, as well as to 'Mesoraphidia' luzzii from the Upper Cretaceous amber of New Jersey, and Cantabroraphidia marcanoi from the Lower Cretaceous El Soplao amber of Spain. For the species 'Mesoraphidia' luzzii a new genus, Grimaldiraphidia, is erected, because it would otherwise render the genus Mesoraphidia paraphyletic. 'Mesoraphidia' durlstonenesis, 'M.' gaoi, 'M.' heteroneura, 'M.' mitchelli, 'M.' parvula and 'M.' purbeckensis are also transferred to this new genus Grimaldiraphidia. Four Cretaceous amber genera comprise minute specimens and represent a distinct clade within Mesoraphidiidae, for which a new tribe, Nanoraphidiini, is proposed. The phylogeny and fossil record of Raphidioptera is discussed and the suborders Priscaenigmatomorpha and Raphidiomorpha are supported. A revised definition and composition of Mesoraphidiidae (including Cretinocellia) is suggested. 'Siboptera' medialis is transferred to the genus Mesoraphidia. The synonymy of Alloraphidiidae with Mesoraphidiidae is rejected and Alloraphidiinae is restored as separate subfamily that probably represents the sister group of Mesoraphidiinae. The genera Caloraphidia, Styporaphidia and Ororaphidia are transferred to a new subfamily Ororaphidiinae within Mesoraphidiidae. The genus Metaraphidia is excluded from Mesoraphidiidae and attributed to a new monotypic family Metaraphidiidae, which is considered as sister group of Neoraphidioptera (Raphidiidae+Inocelliidae) within the new taxon Euraphidioptera, which is the sister group to Mesoraphidiidae within the new taxon Raphidiformia. Arariperaphidia rochai is transferred to "Baissopteridae" that might rather be a paraphyletic grade of basal stem group representatives.

AbstractThe definition of the family Evaniidae is revised and Cretevaniidae are synonymised with Evaniidae based on evidence derived from recently described Mesozoic taxa and a new genus and species, Lebanevania azari, described here from Lebanese amber. A fore leg with a long trochanter and a 12-segmented antenna are autapomorphies of the new genus. A large, high and wide head and a high and short mesosoma are derived characters shared with other Evaniidae. The new genus also has complete fore wing venation and lacks a tubular petiole, which are ground plan features of the Evanioidea. A cladistic analysis of fossil and extant members of the superfamily Evanioidea and notes on fossil taxa are presented.

A new asellotan isopod of the family Protojaniridae Fresi, Idato & Scipione, 1980 is described from freshwater springs in the Osorno province, Los Lagos region, southern Chile. Wiyufiloides osornoensis gen. & sp. n. is the third South American protojanirid species and the first known groundwater isopod in Chile. The new genus and species is principally characterized by the presence of a vestigial antennal scale, a strongly subchelate pereiopod I and the absence of an apical lobe on the protopod of pleopod II. The new taxon is described in detail and figures are given.

The Myristicaceae is a member of the early diverging angiosperm order Magnoliales; however, the family is poorly represented by fossil collections. We describe Virola dominicana sp. nov. (Myristicaceae), the first record of fossilized Myristicaceae flowers, from mid-Tertiary (45–15 million years ago) Dominican amber. The description is based on 24 male flowers in 17 pieces of amber, thus providing some indication of intraspecific variation, including a two-tepaled flower. Diagnostic characters of the new species are the long-simple or few-branched trichomes on the perianth margins, the small pollen grains, and a short staminal column. These fossils also show co-occurring insects, some of which could be Virola pollinators. It is speculated that V. dominicana disappeared from Hispaniola during the Pliocene–Pleistocene cooling events leaving no native members of the Myristicaceae in this region today. Additionally, these fossils demonstrate that Myristicaceae was present in the Western Hemisphere during the mid-Tertiary.

A new genus of lichenized fungi of the family Porinaceae is described, known from Costa Rica and Brazil. Flabelloporina Sobreira, M. Cáceres & Lücking is a thus far monospecific genus with an isolated position of its only species in the family, morphologically different from all other genera in Porinaceae. The genus is characterized by the production of numerous, flabelliform squamules on the surface of the thallus, together with black perithecia and transversally septate ascospores (with three septa in the only species). The new combination Flabelloporina squamulifera (Breuss, Lücking & Navarro) Sobreira, M. Cáceres & Lücking is proposed, based on Porina squamulifera Breuss, Lücking & Navarro, and the species is for the first time reported from Brazil.
