AbstractBabinskaiidae is an extinct family of the lacewing superfamily Myrmeleontoidea, currently only recorded from the Cretaceous. The phylogenetic position of this family is elusive, with inconsistent inferences in previous studies. Here we report on three new genera and species of Babinskaiidae from the mid-Cretaceous Kachin amber of Myanmar, namely Calobabinskaia xiai gen. et sp. nov., Stenobabinskaia punctata gen. et sp. nov., and Xiaobabinskaia lepidotricha gen. et sp. nov. These new babinskaiids are featured by having specialized characters, such as the rich number of presectoral crossveins and the presence of scaly setae on forewing costal vein, which have not yet been found in this family. The exquisite preservation of the Kachin amber babinskaiids facilitate a reappraisal of the phylogenetic placement of this family based on adult morphological characters. Our result from the phylogenetic inference combining the data from fossil and extant myrmeleontoids recovered a monophyletic clade composed of Babinskaiidae and another extinct family Cratosmylidae, and further assigned this clade to be sister group to a clade including Nemopteridae, Palaeoleontidae, and Myrmeleontidae. Babinskaiidae appears to be a transitional lineage between Nymphidae and advanced myrmeleontoids, with ancient morphological diversification.

AbstractThe placement of Diopsina in a monophyletic clade with Diopsis and Eurydiopsis is confirmed and a sister group relationship between Diopsina and Diopsis recovered with moderate support. The clarification of the phylogenetic position of Diopsina nested deeply within Diopsini is of crucial importance for the understanding of the relationships and the evolution of various morphological characters within the family.

New Information

Complete descriptions, as preservation permits, are provided for new Late Jurassic taxa (e.g., †<i>Ascalabothrissops voelkli</i> n. gen. and n. sp., †<i>Anaethalion zapporum</i> n. sp., and †<i>Elopsomolos frickhingeri</i> n. gen. and n. sp.); the phylogenetic positions of these taxa are given, as well as an evaluation of the European teleosts during the Late Jurassic. <br><br> The relationships among certain fossil and extant teleosts are evaluated based on 191 unweighted morphological characters by using cladistic principles. The results suggest that †<i>Ascalabothrissops</i> n. gen. from the Kimmeridgian of Schamhaupten is the sister-taxon of †<i>Pachythrissops</i> from the Tithonian of Bavaria, and consequently is an ichthyodectiform. †<i>Anaethalion zapporum</i> n. sp., an elopiform, stands in an unresolved polytomy with †<i>A. angustus, †A. knorri</i>, and a clade formed by †<i>A. angustissimus</i> and more advanced elopiforms. The new results confirm Arratia (1997) that †<i>Anaethalion</i>, as presently understood, is a paraphyletic taxon. †<i>Elopsomolos frickhingeri</i> n. gen. and n. sp. forms a polytomy with †<i>Elopsomolos</i> sp. 1 and 3, and [<i>Elops + Megalops</i>]. Monophyly of the Kimmeridgian and Tithonian genus †<i>Elopsomolos</i> is not certain. <br><br> Following the new phylogenetic hypothesis, that includes new taxa and new characters, the elopomorphs stand as the primitive sister-group of osteoglossomorphs and more advanced teleosts. The new information does not affect the phylogenetic position of the main extant teleostean clades and confirms previous results by Arratia (1991, 1996, 1997, 1999). <br><br> The analysis of the elopiforms through time shows that the group had an important radiation during the Late Jurassic, to be replaced by new genera and species during the Cretaceous, and again during the Cenozoic. From numerous genera living in the past, elopiforms are represented now by two genera, <i>Elops</i> and <i>Megalops</i>. <br><br> Soweit es die Erhaltung zulässt, werden vollständige Beschreibungen der drei neuen spätjurassischen Taxa †<i>Ascalabothrissops voelkli</i> n. gen. et n. sp., †<i>Anaethalion zapporum</i> n. sp., und †<i>Elopsomolos frickhingeri</i> n. gen. et n. sp. gegeben. Die phylogenetische Stellung dieser Taxa als auch anderer spätjurassischer europäischer Teleosteer ist analysiert. <br><br> Die Verwandtschaftsbeziehungen innerhalb einiger fossiler und rezenter Teleosteer wurden auf der Basis von 191 nicht gewichteten morphologischen Merkmalen mit Hilfe der kladistischen Methode evaluiert. Als Ergebnis zeigt sich, dass †<i>Ascalabothrissops</i> n. gen. aus dem Kimmeridgium von Schamhaupten das Schwestertaxon von †<i>Pachythrissops</i> und damit ein Ichthyodectiformer ist. †<i>Anaethalion zapporum</i> n. sp., ein Elopiformer, steht in einer nicht auflösbaren Polytomie mit †<i>A. angustus, †A, knorri</i>, und einer Gruppe gebildet aus †<i>A. angustissimus</i> und weiter fortgeschrittenen Elopiformen. Die neuen Ergebnisse bestätigen Arratia (1997), dass †<i>Anaethalion</i>, wie zur Zeit umgrenzt, ein paraphylethisches Taxon darstellt. †<i>Elopsomolos frickhingeri</i> n. gen. et n. sp. bildet eine Polytomie mit †<i>Elopsomolos</i> sp. 1 und 3, und [<i>Elops + Megalops</i>]. Die Monophylie der Gattung †<i>Elopsomolos</i> aus dem Kimmeridgium und Tithonium ist nicht gesichert. <br><br> Nach der neuen phylogenetischen Hypothese, die neue Taxa und neue Merkmale einbezieht, sind die Elopomorphen die primitive Schwestergruppe der Osteoglossomorphen und weiter fortgeschrittener Teleosteer.

Rove beetles of the genus Piestus Gravenhorst, 1806 are commonly captured under the bark of or inside decaying logs from Neotropical forests. Piestus belongs to the subfamily Piestinae, historically an ill-defined dumping-ground for Staphylinidae defined by plesiomorphic characters, but which has gradually been restricted in concept and currently includes only six additional extant genera worldwide. Piestinae in this restricted sense has been considered a probably monophyletic subfamily, but its status and phylogenetic position, as a possible sister-group of Osoriinae within the recently proposed Oxyteline group of staphylinid subfamilies, are uncertain and need confirmation. The main aim of the present study was to provide a morphological cladistic analysis and complete taxonomic revision of Piestus, which, as the type and most speciose genus of Piestinae, is critical for future phylogenetic studies involving the subfamily. In our study, the monophyly of Piestus is established and phylogenetic relationships among its species are proposed based on 70 adult morphological characters. Piestus is supported by 11 synapomorphies and high branch support. All species of Piestus are revised and the genus is redefined. The genus contains 43 species, including 13 species described here for the first time. The previously proposed subgenera Antropiestus Bernhauer, 1917, Eccoptopiestus Scheerpeltz, 1952, Elytropiestus Scheerpeltz, 1952, Lissopiestus Scheerpeltz, 1952, Piestus s. str., Trachypiestus Scheerpeltz, 1952 and Zirophorus Dalman, 1821 have not been confirmed, as they were found to be poly- or paraphyletic, or are here removed from Piestus, and therefore subgenera are not used. The main taxonomic changes are as follows. Lissopiestus, syn. nov. is proposed as new synonym of Eleusis Laporte, 1835 and its species, E. interrupta (Erichson, 1840), comb. rest., is transferred again to that genus. Antropiestus, syn. nov. and Eccoptopiestus, syn. nov. are proposed as new synonyms of Hypotelus Erichson, 1839 and their species, H. laevis (Solsky, 1872), comb. nov. and H. andinus (Bernhauer, 1917), comb. nov., are transferred to Hypotelus. Fourteen new synonymies are proposed (valid species listed first): P. lacordairei Laporte, 1835 = Z. furcatus Sharp, 1887, syn. nov.; P. capricornis Laporte, 1835 = P. frontalis Sharp, 1876, syn. nov.; P. pennicornis Fauvel, 1864 = P. plagiatus Fauvel, 1864, syn. nov.; P. rectus Sharp, 1876, syn. nov.; P. pygialis Fauvel, 1902, syn. nov.; P. surinamensis Bernhauer, 1928, syn. nov.; P. minutus Erichson, 1840 = P. nigrator Fauvel, 1902, syn. nov.; P. sulcatus Gravenhorst, 1806 = P. sanctaecatharinae Bernhauer, 1906, syn. nov.; P. condei Wendeler, 1955, syn. nov.; P. gounellei Fauvel, 1902 = P. wasmanni Fauvel, 1902, syn. nov.; P. mexicanus Laporte, 1835 = P. alternans Sharp, 1887, syn. nov.; P. aper Sharp, 1876 = P. schadei Scheerpeltz, 1952, syn. nov.; P. angularis Fauvel, 1864 = P. crassicornis Sharp, 1887, syn. nov.; H. andinus (Bernhauer, 1917) = P. strigipennis Bernhauer, 1921, syn. nov. One species is revalidated: P. fronticornis (Dalman, 1821), stat. rev., and one synonym is restored: P. penicillatus (Dalman, 1821) = P. erythropus Erichson, 1840, syn. rest. Neotypes are designated for P. lacordairei Laporte, 1835 and Oxytelus bicornis Olivier, 1811, and lectotypes are designated for P. puncticollis Fauvel, 1902, P. capricornis variety muticus Fauvel, 1902, P. zischkai Scheerpeltz, 1951, P. pennicornis Fauvel, 1864, P. plagiatus Fauvel, 1864, P. pygmaeus Laporte, 1835, P. niger Fauvel 1864, P. minutus Erichson, 1840, P. nigratror Fauvel, 1902, P. sulcatus Gravenhorst, 1806, P. sanctaecatharinae Bernhauer, 1906, P. sulcipennis Scheerpeltz, 1952, P. aper Sharp, 1876, P. schadei Scheerpeltz, 1952 and P. andinus Bernhauer, 1917.

The phylogenetic placement of Chapsa lamellifera, C. megalophthalma and Diploschistes ocellatus was studied using a dataset of five genetic markers (mtSSU, nuLSU, RPB1, RPB2 and ITS). As extratropical species occurring in Australasia, C. lamellifera and C. megalophthalma differ from other species in that genus by having relatively large ascomata with muriform ascospores and complex chemistry of either the protocetraric or stictic acids chemosyndrome. D. ocellatus is unique within Diploschistes, in lacking lateral paraphyses and containing the norstictic acid chemosyndrome. Previous phylogenetic analysis gave inconclusive results regarding the phylogenetic position of these taxa, and hence in the present study, a larger sampling of molecular markers was employed. Our results demonstrated that the two Chapsa species and D. ocellatus are not part of their current genera. Consequently, the new genera Gintarasia Kraichak, Lücking &amp; Lumbsch and Xalocoa Kraichak, Lücking &amp; Lumbsch are described to accommodate these species. The new combinations Gintarasia lamellifera (Kantvilas &amp; Vězda) Kraichak, Lücking &amp; Lumbsch, G. lordhowensis (Mangold) Kraichak, Lücking &amp; Lumbsch, G. megalophthalma (Müll. Arg.) Kraichak, Lücking &amp; Lumbsch and Xalocoa ocellata (Vill.) Kraichak, Lücking &amp; Lumbsch are also proposed.

We provide an updated skeleton phylogeny of the lichenized family Graphidaceae (excluding subfamily Gomphilloideae), based on three loci (mtSSU, nuLSU, RPB2), to elucidate the position of four new genera, Aggregatorygma, Borinquenotrema, Corticorygma, and Paratopeliopsis, as well as the placement of the enigmatic species Diorygma erythrellum, Fissurina monilifera, and Redingeria desseiniana. Based on the resulting topology, in addition to three tribes described previously, we recognize four further tribes in the subfamily Graphidoideae: Acanthothecieae Lumbsch, Kraichak & Lücking, Diploschisteae (Zahlbr.) Lumbsch, Kraichak & Lücking, Leptotremateae Lumbsch, Kraichak & Lücking, and Wirthiotremateae Lumbsch, Kraichak & Lücking. The phylogenetic position of Aggregatorygma and Borinquenotrema was not resolved with support, whereas Corticorygma forms part of Acanthothecieae, supported sister to Acanthothecis, and Paratopeliopsis belongs in Thelotremateae, unsupported sister to Leucodecton. Diorygma erythrellum is confirmed as a member of the Diorygma-Thalloloma clade, while Fissurina monilifera, inspite of its myriotremoid ascomata, belongs in Fissurina s.str. Redingeria dessiniana, although resembling the genus Phaeographopsis, is supported sister to R. glaucoglyphica. Topeliopsis darlingtonii forms the sister group to Gintarasia megalophthalma. Consequently, T. darlingtonii and the closely related T. elixii are recombined in Gintarasia as Gintarasia darlingtonii (Frisch & Kalb) Lumbsch, Kraichak & Lücking, and G. elixii (Frisch & Kalb) Lumbsch, Kraichak & Lücking.

Basal Position

Male secondary genitalia (pedipalps) are useful characters for species discrimination in most spider families. Although efforts have been made to establish pedipalp sclerite homologies, there are still many inconsistencies in their use. The majority of the morphological characters used to reconstruct the linyphiid phylogeny address male genitalic variation; these inconsistencies may affect the phylogeny and our understanding of linyphiid evolution. Stemonyphantes Menge, 1866, has been hypothesised to be sister to all remaining Linyphiidae. However, despite the basal position of Stemonyphantes, its pedipalp sclerite homologies are not well understood and, along with its monophyly, have never been thoroughly tested in a phylogenetic context. We tested the homology of tegular and radical structures of five Stemonyphantes species to the known linyphioid and araneoid sclerites. All minimum-length trees found under all analytical methods used support Stemonyphantes monophyly and its placement as the sister group to all other Linyphiidae. Our study suggests that Stemonyphantes, unlike any other linyphiids, does have homologues of the araneoid median apophysis and conductor. As Stemonyphantes is the sister group of all other linyphiids, resolving its pedipalp sclerite homologies is critical for understanding sclerite homologies and the phylogeny of the entire family.

A phylogenetic analysis of selected anomuran, thalassinidean, and other decapod crustacean taxa, based on spermatozoal ultrastructural characters and spermatophore morphological characters, was performed and the following relationships of the taxa are elucidated from the trees produced. The Anomura are not a monophyletic assemblage, with the lomoid Lomis being exclusive of the remainder of the anomuran taxa, and the thalassinid Thalassina included in the anomuran clade. The synapomorphy joining the majority of the conventional anomuran taxa (Lomis excluded) is the cytoplasmic origin of the microtubular arms. When the palinurid and thalassinoid representatives are separately designated as outgroups, the Astacidea and Brachyura jointly formed a sister group to the Anomura. The superfamilies Thalassinoidea, Paguroidea, and Galatheoidea are not monophyletic groups. In all analyses the anomuran families Coenobitidae and Porcellanidae each form a monophyletic group. The paguroid family Diogenidae is paraphyletic, with the genera Clibanarius and Cancellus separate from a single clade containing the remaining diogenid genera. The families Paguridae and Parapaguridae form a monophyletic clade with the exception of Porcellanopagurus. The two representatives of the family Chirostylidae (Eumunida and Uroptychus) fail to associate with the other species in the Galatheoidea. The taxa in the family Galatheidae are not a monophyletic assemblage. The only investigated hippoid Hippa is portrayed as the sister group to the remainder of the anomuran taxa (with the exception of Lomis).

The genus Holopodostreptus Carl, 1913 is a poorly known monotypic genus endemic to Ecuador. It differs from most other Pseudonannolenidae by a set of characteristics of the gnathochilarium and gonopods. Herein, we provide descriptive notes of males of H. braueri Carl, 1913 based on recently collected material. Females of the species are described for the first time, and images of the vulvae are provided. In addition, we attempt for the first time to place Holopodostreptus in a phylogenetic context. With a total of 14 taxa and 41 morphological characters, and under implied weighting (k = 6), a single most-parsimonious tree is recovered (total fit = 35.86). The genus is recovered as sister-group of Physiostreptus Silvestri, 1903. The clade Holopodostreptus + Physiostreptus is supported by one synapomorphy (absence of setae on the prefemoral process of leg-pair 1 in males) and one homoplastic transformation (narrow telopodite). Based on the phylogenetic results, notes on the subfamilies Pseudonannoleninae, Cambalomminae and Physiostreptinae and a key for all pseudonannolenid genera are provided.
