Small but not ephemeral: newly discovered species of Aphelinidae and Trichogrammatidae (Insecta: Hymenoptera: Chalcidoidea) from Eocene amber

New species of fossil Aphelinidae and Trichogrammatidae are described from middle Eocene (Lutetian) Baltic amber (41.3–47.8 Ma). A new subfamily, two new genera and three new species of Aphelinidae are described, with comments on their placement: Phtuaria fimbriae gen.n. , sp.n. in Phtuariinae subf.n. , Glaesaphytis interregni gen.n. , sp.n. and Centrodora brevispinae sp.n. These represent the first described true fossil Aphelinidae. Four new species of Trichogrammatidae are described: Mirufens illusionis sp.n. , Palaeogramma eos gen.n. , sp.n. , Pterandrophysalis plasmans sp.n. and Szelenyia terebrae sp.n. , thus expanding our knowledge of fossil Trichogrammatidae beyond the single previously described species. The presence of recognizable extant genera of Aphelinidae and Trichogrammatidae in the Eocene suggests that the morphology of these genera has been relatively invariant despite highly variable conditions during and since the Eocene.

Molecular phylogeny and systematics of Australian ‘Iravadiidae’ (Caenogastropoda: Truncatelloidea)

The family Iravadiidae is found to be polyphyletic in a molecular phylogenetic analysis using a subset of Australian taxa. Taxa previously assigned to Iravadia form a monophyletic clade, but Nozeba topaziaca clusters with Auricorona queenslandica n. gen. and n. sp. in an unnamed family related to Tornidae. Aenigmula criscionei n. gen. and n. sp., an iravadiid-like species from the Northern Territory, belongs to another unnamed family related to Caecidae, Calopiidae and Clenchiellidae. A systematic revision of some Australian ‘iravadiids’ raises the subgenera Fluviocingula and Pseudomerelina to full generic rank and reinstates two former synonyms of Iravadia (Fairbankia), Pellamora and Wakauraia, as genera. The species formerly identified in Australia as Iravadia quadrasi is recognised as three allopatric species; Iravadia pilbara n. sp. and the reinstated species Iravadia goliath and Iravadia quadrina. Pellamora splendida n. sp., from Western Australia, is recognised as distinct from Pellamora australis, and Fluviocingula superficialis n. sp. from Fluviocingula resima. Wakauraia fukudai n. sp. is recorded from central Queensland.

Fossil water striders in Cretaceous French amber (Heteroptera: Gerromorpha: Mesoveliidae and Veliidae)

Fossil gerromorphan bugs from the Cretaceous (Albian–Cenomanian boundary) amber of Charentes, SW France, are reviewed. A larva described by Perrichot et al. (2005) as incertae familiae within the Gerromorpha is now placed in the Mesoveliidae. Three new genera and species are also described and illustrated: Emilianovelia audax Solórzano Kraemer & Perrichot, gen. et sp.n. , and Malenavelia videris Solórzano Kraemer & Perrichot, gen. et sp.n. , which are placed in the Mesoveliidae: Mesoveliinae; and Arcantivelia petraudi Solórzano Kraemer & Perrichot, gen. et sp.n. , which is the first Mesozoic member of the Veliinae. The relationships between these fossils and their palaeoecology are discussed. The new discoveries confirm the antiquity of the semi‐aquatic gerromorphans, particularly the clade (Veliidae + Gerridae). The habitat is described as aquatic and likely marine‐influenced, yet adaptation to a fully marine habitat in these gerromorphans remains difficult to establish.

Phylogeny of Evanioidea (Hymenoptera,Apocrita), with descriptions of new Mesozoic species from China and Myanmar

The phylogeny of the superfamily Evanioidea is presented using morphology and DNA sequence data of selected extant and fossil genera by employing two phylogenetic methods, maximum parsimony and Bayesian inference. Based on our new results, the monophyly of Evanioidea is corroborated. Evanioidea, Anomopterellidae, Othniodellithidae, Andreneliidae and Evaniidae are monophyletic families, while Praeaulacidae, Aulacidae, Baissidae and Gasteruptiidae are paraphyletic families. In addition, four new genera (Sinuevania gen.n. , Curtevania gen.n. , Exilaulacus gen.n. , Heterobaissa gen.n. ) with five new species (Sinuevania mira sp.n. , Curtevania enervia sp.n. , Exilaulacus loculatus sp.n. , Exilaulacus latus sp.n. , Heterobaissa apetiola sp.n. ), and five additionally new species (Newjersevania longa sp.n. , Newjersevania brevis sp.n. , Cretevania tenuis sp.n. , Cretevania venae sp.n. , Praeaulacus rectus sp.n. ) and one new combination [Cretevania mitis (Li, Shih & Ren, 2014a) comb.n. ] are described based on well‐preserved fossils from the Middle Jurassic Jiulongshan Formation in Inner Mongolia, China, the Early Cretaceous Yixian Formation in Liaoning, and mid‐Cretaceous amber from Myanmar. This study documents the diversification of one major lineage of the mid‐Mesozoic parasitoid revolution that dramatically changed food‐web relationships in terrestrial ecosystems.

New fossils from China elucidating the phylogeny of Praesiricidae (Insecta: Hymenoptera)

A new subfamily of Praesiricidae (Pamphilioidea), Decorisiricinae subfam.n. , is erected based on three new genera: Decorisiricius gen.n. , Limbisiricius gen.n. and Brevisiricius gen.n. Two new species – Decorisiricius patulus gen. et sp.n. and D. longus sp.n. – from the Lower Cretaceous Yixian Formation and three species –Limbisiricius aequalis gen. et sp.n. , Limbisiricius complanatus sp.n. and Brevisiricius partialis gen. et sp.n. – from the Middle Jurassic Jiulongshan Formation, are described. Based on these well‐preserved new fossil specimens and previously published data, the nonmonophyly of Praesiricidae is confirmed and the phylogenetic relationships of species of Praesiricidae are analysed for the first time. Two main clades within Praesiricidae are recognized from the cladistic analysis: Decorisiricinae subfam.n. forms a monophyletic lineage, with the remaining members of Praesiricidae plus Megalodontes (Megalodontesidae) forming its sister group. The two subfamilies Archoxyelydinae and Praesiricinae are discarded with no strong supported synapomorphic characters based on phylogenetic research. A key to all genera of Praesiricidae is provided.

A new genus of mantidflies discovered in the Oriental region,with a higher‐level phylogeny of Mantispidae (Neuroptera) using DNA sequences and morphology

A remarkable new genus and two new species of Mantispidae (Neuroptera) are described from the Oriental region. Allomantispa Liu, Wu, Winterton & Ohl gen.n. , currently including A. tibetana Liu, Wu & Winterton sp.n. and A. mirimaculata Liu & Ohl sp.n. The new genus is placed in the subfamily Drepanicinae based on a series of morphological characteristics and on the results of total evidence phylogenetic analyses. Bayesian and Parsimony analyses were undertaken using three gene loci (CAD, 16S rDNA and COI) combined with 74 morphological characters from living and fossil exemplars of Mantispidae (17 genera), Rhachiberothidae (two genera) and Berothidae (five genera), with outgroup taxa from Dilaridae and Osmylidae. The resultant phylogeny presented here recovered a monophyletic Mantispidae with ?Mesomantispinae sister to the rest of the family. Relationships among Mantispidae, Rhachiberothidae and Berothidae support Rhachiberothidae as a separate family sister to Mantispidae. Within Mantispidae, Drepanicinae are a monophyletic clade sister to Calomantispinae and Mantispinae. In a combined analysis, Allomantispa gen.n. was recovered in a clade comprising Ditaxis McLachlan from Australia, and two fossil genera from the Palaearctic, ?Promantispa Panfilov (Kazakhstan; late Jurassic) and ?Liassochrysa Ansorge & Schlüter (Germany; Jurassic), suggesting a highly disjunct and relictual distribution for the family.

A remarkable new opsiine leafhopper genus (Hemiptera: Cicadellidae: Deltocephalinae) from Southern China,with notes on its phylogenetic position

A remarkable new genus of tribe Opsiini (Deltocephalinae), Yinformibus gen. nov. including Yinformibus menglaensis sp. nov. is described from Yunnan of China. The new genus is placed in the tribe Opsiini based on male adults having a pair of aedeagal shafts, each with its own gonopore. Partial 28S rDNA and Histone H3 sequences are provided for the new species, and a phylogenetic analysis based on these markers for Deltocephalinae retrieved from GenBank suggests Opsiini is monophyletic and supports the placement of Yinformibus gen. nov. in Opsiini. The molecular results placed the new genus in a clade comprising Hishimonus Ishihara, Opsius Fieber, and an undescribed genus from Zambia. Additionally, we also analysed the relationships of Yinformibus gen. nov. with other genera based on morphology.

Cladispa Baly: revision,biology and reassignment of the genus to the tribe Spilophorini (Coleoptera: Chrysomelidae: Cassidinae)

The genus, Cladispa Baly 1858, is transferred from the tribe Imatidiini (= Cephaloleiini Chapuis, 1875) to Spilophorini Chapuis, 1875 based on the review of type material, newly collected specimens and molecular phylogenetic analysis. The type species, C. quadrimaculata Baly, 1858, is redescribed, and two new species, C. amboroensis sp.n. from Bolivia (Santa Cruz Department) and C. ecuadorica sp.n. from Ecuador (Pastaza Province), are described and figured. The morphology of C. amboroensis sp.n. immature stages is broadly consistent with other Spilophorini. Field observations document that both C. quadrimaculata and C. amboroensis sp.n. are trophic specialists on Orchideaceae. Keys to Cladispa species and Spilophorini genera are provided. Trophic associations of other Cassidinae and Orchideaceae are discussed.

Long‐proboscid brachyceran flies in Cretaceous amber (Diptera: Stratiomyomorpha: Zhangsolvidae)

The monophyletic family Zhangsolvidae comprises stout‐bodied brachyceran flies with a long proboscis and occurring only in the Cretaceous, originally known in shale from the Early Cretaceous Laiyang Formation (Fm.) in China (Zhangsolva Nagatomi & Yang), subsequently from limestones of the Early Cretaceous Crato Fm. of Brazil. Cratomyoides Wilkommen is synonymized with Cratomyia Mazzarolo & Amorim, both from the Crato Fm.; Cratomyiidae is synonymized with Zhangsolvidae. Two genera and three species of Zhangsolvidae are described: Buccinatormyia magnifica Arillo, Peñalver & Pérez‐de la Fuente, gen. et sp.n. and B. soplaensis Arillo, Peñalver & Pérez‐de la Fuente, sp.n. , in Albian amber from Las Peñosas Fm. in Spain; and Linguatormyia teletacta Grimaldi, gen. et sp.n. , in Upper Albian–Lower Cenomanian amber from Hukawng Valley in Myanmar. Buccinatormyia soplaensis and Linguatormyia teletacta are unique among all Brachycera, extant or extinct, by their remarkably long, flagellate antennae, about 1.6× the body length in the latter species. A phylogenetic analysis of 52 morphological characters for 35 taxa is presented, 11 taxa being Cretaceous species, which supports placement of the family within Stratiomyomorpha, although not to any particular family within the infraorder.

A new genus of schizomids (Arachnida: Schizomida: Hubbardiidae) from Mexico,with notes on its systematics

During the systematic revision of Mayazomus, the third most diverse genus of micro whip-scorpions in North America, we found three species with peculiar morphological variation, which are different from those diagnostic characters for Mayazomus. These species share with Mayazomus the large body size and the unusual development of the male pedipalps; however, these three species share the shape of the female spermathecae with Stenochrus rather than with Mayazomus. Therefore, their phylogenetic placements create a dilemma. Here we perform analyses with morphological evidence, using two different methodologies (Parsimony and Bayesian inference) in order to hypothesize the phylogenetic relationships of the three species mentioned with each other and with respect to other North American and/or Central American genera. The results confirm our initial hypothesis that the species belong to a different genus, Olmeca gen. nov., which is recovered as the sister group of all hubbardiine genera included in these analyses, except for the genus Hubbardia. The results also indicate that despite sharing some morphological similarities, it is distantly related with Mayazomus. Three species are described herein: Olmeca brujo sp. nov., Olmeca cruzlopezi sp. nov., and Olmeca santibanezi sp. nov. Additionally, we provide a hypothesis of the relationships and biogeography of Olmeca gen. nov. with other genera.

Diverse oxyporine rove beetles from the Early Cretaceous of China (Coleoptera: Staphylinidae)

Two new genera and species, Protoxyporus grandis gen. et sp.n. and Cretoxyporus extraneus gen. et sp.n. , are described and figured on the basis of two well‐preserved impression fossils from the Lower Cretaceous Yixian Formation of China. The two genera display a combination of traits that are diagnostic of the extant staphylinid subfamily Oxyporinae: large and prominent mandibles, distinctly separated mesocoxae, abdominal tergites III–VII each with a pair of basolateral ridges, and abdominal intersegmental membranes with ‘brick‐wall’ pattern. Protoxyporus differs from extant Oxyporus in retaining the following plesiomorphic features: an elongate intercoxal process (or longitudinal carina) between metacoxae, relatively narrowly separated mesocoxae, less developed metaventral anterior process, and long infraorbital ridges. Cretoxyporus is morphologically very similar to Oxyporus, but retains distinct elongate infraorbital ridges. The discovery of two new oxyporine genera suggests that the early oxyporines were more diverse and their evolutionary history more complicated than previously documented.

Molecular phylogeny of the tribe Candalidini (Lepidoptera: Lycaenidae): systematics,diversification and evolutionary history

The butterfly tribe Candalidini is geographically restricted to Australia and mainland New Guinea and its adjacent islands. With 60 species and subspecies, it represents a large radiation of Papilionoidea in the Australian region. Although the species-level taxonomy is relatively well understood, the number of genera is uncertain, varying from two to eight. We reconstructed the phylogeny of the Candalidini based on a 13-locus hybrid enrichment probe set (12.8 Kbp: COI, Thiolase, CAD, CAT, DDC, EF1-a, GAPDH, HCL, IDH, MDH, RPS2, RPS5, Wingless), including all previously recognized genera and 76% (28/37) of the species-level diversity of the tribe. Maximum likelihood analysis recovered the Candalidini as a strongly supported monophyletic group. In conjunction with morphological characters, the phylogeny provided a robust framework for a revised classification in which we recognize four genera, 37 species and 23 subspecies. The genus Nesolycaena Waterhouse & R.E. Turner is considered in synonymy with Candalides Hübner, and four other genera are not recognized, namely, Holochila C. Felder, Adaluma Tindale, Zetona Waterhouse and Microscena Tite. Of the four valid genera, the absimilis group (23 species) is placed in the newly described genus Eirmocides Braby, Espeland & Müller gen. nov. (type species Candalides consimilis Waterhouse). The erinus group (six species) is assigned to Erina Swainson, which is reinstated. Chrysophanus cyprotus Olliff is assigned to Cyprotides Tite, which is also reinstated as a monotypic genus. The remaining seven species are placed in Candalides sensu stricto. Overall, we propose 47 new nomenclatural changes at the species and subspecies levels, including the synonymy of Holochila biaka Tite as Eirmocides tringa biaka (Tite) syn. nov. et comb. nov. and recognition of Candalides hyacinthinus gilesi M.R. Williams & Bollam as a distinct species Erina gilesi (M.R. Williams & Bollam stat. rev. et comb. nov. A dated phylogeny using Bayesian inference in BEAST2 and biogeographical and habitat analyses based on the DEC model in BioGeoBEARS indicated that the ancestor of the Candalidini most likely evolved in rainforest habitats of the mesic biome in situ on the Australian plate of Southern Gondwana during the Eocene (c. 43 Ma). A major period of diversification occurred in the Miocene, which coincided with aridification of the Australian continent, followed by a further episode of radiation in montane New Guinea during the Plio-Pleistocene.

Systematics and evolution of gall formation in the plant‐associated genera of the wasp subfamily Doryctinae (Hymenoptera: Braconidae)

Gall formation is a specialised form of phytophagy that consists of abnormal growth of host plant tissue induced by other organisms, principally insects and mites. In the mainly parasitoid wasp subfamily Doryctinae, gall association, represented by gall inducers, inquilines and their parasitoids, is known for species of seven genera. Previous molecular studies recovered few species of six of these genera as monophyletic despite their disparate morphologies. Here, we reconstructed the evolutionary relationships among 47 species belonging to six gall‐associated doryctine genera based on two mitochondrial and two nuclear gene markers. Most of the Bayesian analyses, performed with different levels of incomplete taxa and characters, supported the monophyly of gall‐associated doryctines, with Heterospilus (Heterospilini) as sister group. Percnobracon Kieffer and Jörgensen and Monitoriella Hedqvist were consistently recovered as monophyletic, and the validity of the monotypic Mononeuron was confirmed with respect to Allorhogas Gahan. A nonmonophyletic Allorhogas was recovered, although without significant support. The relationships obtained and the gathered morphological and biological information led us to erect three new genera originally assigned to Psenobolus: Ficobolus gen.n. (F. paniaguai sp.n. and F. jaliscoi sp.n. ), Plesiopsenobolus gen.n. (Pl. mesoamericanus sp.n. , Pl. plesiomorphus van Achterberg and Marsh comb.n. , and Pl. tico sp.n. ), and Sabinita gen.n. (S. mexicana sp.n. ). The origin of the gall‐associated doryctine clade was estimated to have occurred during the middle Miocene to early Oligocene, 16.33–30.55 Ma. Our results support the origin of true gall induction in the Doryctinae from parasitoidism of other gall‐forming insects. Moreover, adaptations to attack different gall‐forming taxa on various unrelated plant families probably triggered species diversification in the main Allorhogas clade and may also have promoted the independent origin of gall formation on at least three plant groups. Species diversification in the remaining doryctine taxa was probably a result of host shifts within a particular plant taxon and shifts to different plant organs.
