Short Summary

This paper targets the nearly cosmopolitan weevil subfamily Lixinae. A phylogenetic analysis of one mitochondrial and two nuclear DNA fragments obtained from 87 Lixinae and 49 outgroup terminals strongly supports the monophyly of the subfamily. The molytine tribe Mecysolobini is the likeliest sister group of Lixinae; adults of both taxa share the likely synapomorphic condition of the greatly shortened labial palpi. Phylogenetic relationships within the subfamily are poorly resolved. None of three Lixinae tribes is recovered as monophyletic. The subfamily’s oldest dichotomy is formed by a clade of two genera Rhabdorrhynchus plus Pachycerus sister to the rest of the subfamily. The genera Chromonotus, Larinus, Lixus, and Stephanocleonus are recovered as non-monophyletic. The genera Asproparthenis, Chromonotus, and Maximus form a strongly supported clade. The genus Eumecops is the likeliest sister to the clade formed by the genera Stephanocleonus plus Coniocleonus. The cleonine genus Scaphomorphus is a sister to a subset of externally most similar species of the genus Lixus; the same clade likely includes the genus Lixoglyptus not represented in the analysis. As an aside we provide a short summary of active flight in adult Cleonini.

A New Species

ABSTRACT A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new species described herein. Dasyloricaria have a restricted trans-Andean distribution, with D . filamentosa occurring at the lower and middle Magdalena, lower Cauca, and Sinu in Colombia, and lago Maracaibo basin in Colombia and Venezuela; D . latiura in the Atrato and the Tuyra basins in Colombia and Panama, respectively; and the new species in the upper and middle Magdalena basin in Colombia. New synonyms for D . filamentosa and D . latiura are proposed, and a lectotype is designated for the latter. Dasyloricaria is herein recognized as monophyletic, with D . filamentosa as the sister group of D . latiura , and the new speciesas sister to that clade. Spatuloricaria is hypothesized to be the sister group of Dasyloricaria based on synapomorphies of the neurocranium, branchial arches and external morphology features. The subtribe Rineloricariina was partially corroborated through the phylogenetic analysis. An identification key for the species of Dasyloricaria is provided.

A phylogenetic analysis using 28S and 18S rDNA provides evidence that the tribe Eucraniini is a monophyletic group and the sister-group of the Phanaeini and Dichotomiini. Our molecular phylogeny of the dung beetle tribes provides strong evidence for the monophyly of the subfamily Scarabaeinae. The monophyly of the tribe Eucraniini is well supported and it includes the genera Anomiopsoides Blackwelder, Ennearabdus van Lansberge, Eucranium Brullé and Glyphoderus Westwood. The food-lifting relocation behaviour present in species of Eucranium, Anomiopsoides and Glyphoderus is considered a derived condition and it most probably evolved from tunnelling behaviour. The preference for dry dung or dung pellets by species of Eucraniini genera, and feeding on plant material by species of Anomiopsoides, are considered apomorphic. Our analyses suggest that rolling behaviour in the Scarabaeinae evolved at least twice during their evolution. The incidence of high endemicity of dung beetles in the Monte biogeographic province of Argentina suggests that the area constitutes an independent centre of evolution. Our hypothesis is that a vicariant event was responsible for the divergence of the Eucraniini from a Neotropical lineage ancestral to Eucraniini and Phanaeini. The isolation of the Eucraniini lineage probably occurred after the Andean uplift during the Quechua diastrophism (middle Miocene) that resulted in the creation of xeric plains in austral regions of South America.

Morphological And Molecular Data

Although the taxonomy of the ca 18 000 species of butterflies and skippers is well known, the family-level relationships are still debated. Here, we present, to our knowledge, the most comprehensive phylogenetic analysis of the superfamilies Papilionoidea, Hesperioidea and Hedyloidea to date based on morphological and molecular data. We reconstructed their phylogenetic relationships using parsimony and Bayesian approaches. We estimated times and rates of diversification along lineages in order to reconstruct their evolutionary history. Our results suggest that the butterflies, as traditionally understood, are paraphyletic, with Papilionidae being the sister-group to Hesperioidea, Hedyloidea and all other butterflies. Hence, the families in the current three superfamilies should be placed in a single superfamily Papilionoidea. In addition, we find that Hedylidae is sister to Hesperiidae, and this novel relationship is supported by two morphological characters. The families diverged in the Early Cretaceous but diversified after the Cretaceous–Palaeogene event. The diversification of butterflies is characterized by a slow speciation rate in the lineage leading to Baronia brevicornis , a period of stasis by the skippers after divergence and a burst of diversification in the lineages leading to Nymphalidae, Riodinidae and Lycaenidae.

Phylogenetic Framework

The first-instar larva of the genus Arthropterus W.S. MacLeay, 1838 is described and illustrated. This is the first description of a newly hatched (first-instar) larva in the myrmecophilous tribe Paussini and the first known larva from a basal paussine lineage. A phylogenetic analysis of the subfamily based on larval characters confirms the placement of the genus Arthropterus as a sister-group of the remaining Paussini and supports the hypothesis that Metriini is the sister-group of Ozaenini+Paussini, with 'Ozaenini' as a paraphyletic group. Within this phylogenetic framework, we reassess which larval characters are diagnostic of the tribes Paussini and Ozaenini. Several larval features of Arthropterus, such as the riddled sensilla S-VIII and the fused terminal disk, are interpreted as adaptations to myrmecophily. This interpretation supports the hypothesis that larvae have played an important role in the evolution of myrmecophily within the subfamily Paussinae.

Swimming Leg

Uncovering the systematics of CopepodaHarpacticoida, the second-most abundant component of the meiobenthos after Nematoda, is of major importance for any further research dedicated especially to ecological and biogeographical approaches. Based on the evolution of the podogennontan first swimming leg, a new phylogenetic concept of the Ancorabolidae Sars and Cletodidae T. Scott sensu Por (Copepoda, Harpacticoida) is presented, using morphological characteristics. It confirms the polyphyletic status of the Ancorabolidae and its subfamily Ancorabolinae Sars and the paraphyletic status of the subfamily Laophontodinae Lang. Moreover, it clarifies the phylogenetic relationships of the so far assigned members of the family. An exhaustive phylogenetic analysis was undertaken using 150 morphological characters, resulting in the establishment of a now well-justified monophylum Ancorabolidae. In that context, the Ancorabolus-lineage sensu Conroy-Dalton and Huys is elevated to sub-family rank. Furthermore, the membership of Ancorabolina George in a rearranged monophylum Laophontodinae is confirmed. Conversely, the Ceratonotus-group sensu Conroy-Dalton is transferred from the hitherto Ancorabolinae to the Cletodidae. Within these, the Ceratonotus-group and its hypothesised sister-group Cletodes Brady are combined to form a monophyletic subfamily Cletodinae T. Scott, subfam. nov. Consequently, it was necessary to restructure the Ancorabolidae, Ancorabolinae and Laophontodinae and extend the Cletodidae to include the displacement and exclusion of certain taxa. Moreover, comparison of the Ancorabolidae, Cletodidae, Laophontoidea and other Podogennonta shows that the Ancorabolidae and Cletodidae form sister-groups in a monophylum Cletodoidea Bowman and Abele, which similarly has a sister-group-relationship with the Laophontoidea T. Scott. According to the present study, both taxa constitute a derived monophylum within the Podogennonta Lang.

Stratigraphic Position

Phylogenetic relationships within the neogastropod family Nassariidae are poorly understood as are relationships between the Nassariidae and other fossil and extant buccinid taxa. The poor resolution of nassariid and buccinoidean relationships is due to: 1) the complex distribution among these gastropods of characters commonly used in classification; 2) a number of Mesozoic and Paleogene genera whose relationships to extant buccinoidean lineages are poorly constrained; and 3) a lack of previous efforts to address these problems on a rigorous, phylogenetic basis.The results of a phylogenetic analysis of nassariid genera did not decisively support the monophyly of the family. The buccinid subfamily Photinae was an extant sister group to the Nassariinae in a phylogenetic analysis of extant taxa and on many cladograms from an analysis combining fossil and extant taxa. In addition, Buccitriton (representing the Paleogene Tritiaria group) was a sister taxon to the Nassariinae in all analyses in which it was included, regardless of the identity of the extant nassariine sister group. This suggests that the photines, which likely arose from a Tritiaria ancestor, are the closest living relatives to the Nassariinae. Many Paleogene fossil “buccinoid” taxa appear to be more distantly related to the Nassariinae and possibly to the rest of the nassariids as well. Stratigraphic range data combined with the results of this study suggest that the Nassariinae diversified rapidly in the early Miocene and achieved a cosmopolitan distribution early in their history. A largely Indo-Pacific subclade was consistently deeply-nested within the Nassariinae, suggesting that nassariines invaded the Indo-Pacific region most recently. The timing of this invasion is difficult to estimate but had occurred by the end of the Miocene. Further analyses using molecular sequence data, relative stratigraphic position, or focusing in more detail on the Paleogene taxa are required to resolve the identity of the sister group to the Nassariinae with greater confidence.

The taxonomy of the genus Crozetia Davies (Diptera: Simuliidae) is reviewed. Apart from the eggs, all stages of Crozetia crozetensis (Womersley) and Cr. seguyi Beaucournu-Saguez and Vernon, are fully redescribed with only claws and genitalia detailed for the female of Cr. crozetensis. A phylogenetic analysis of the Simuliidae indicates that Crozetia is the sister group of all other members of the extant Simuliini, in agreement with current molecular evidence. Palaeogeological evidence on the age of the Crozet Islands is equivocal, but a very late Cretaceous to early Eocene age (79-54 Mya) is most likely, hence the presence of simuliids on this archipelago is not the result of vicariance from Gondwanaland. Method of dispersal to the Crozet Archipelago may have been via wind or possibly vectored by birds from Africa, as suggested by presence of a basal tooth on the adult female claw. Morphometric analysis of larvae of Cr. seguyi indicates seven instars which is typical for the Simuliidae.

The Status

The butterfly tribe Baorini Doherty, 1886 is a large group of skippers. In this study, a total of 8 genera and 41 species of putative members of this tribe, which represent most of the generic diversity and nearly all the species diversity of the group in China, were sequenced for two mitochondrial genes and three nuclear genes (2084 bp). Phylogenetic relationships and subdivision of this tribe were investigated and the status of the genera are discussed. Partitioned maximum likelihood analyses were performed based on the combined dataset. Our results suggest that the data are split into two well-supported clades in the phylogeny tree. This analysis also represents the most complete phylogenetic analysis of the tribe Baorini in China to date, and includes several genera and species that have been previously excluded from published phylogenies of this group.

Sister Relationships

The genus Priochirus Sharp (Coleoptera : Staphylinidae) is a rove beetle group with great variation in cephalic structures, especially the teeth on the frontal margin of head. In this paper, phylogenetic relationships among ten subgenera of the genus Priochirus sensu lato, and of Priochirus and other genera of the tribe Leptochirini are analysed. A cladistic analysis was conducted based on 62 characters of adult morphology. Results indicate that the genus Priochirus is not a monophyletic group and is divided into two lineages (called here Lineages I and II respectively). The subgenus Euleptarthrus Jakobson, which included three species-groups (japonicus, longicornis and malayanus), is shown to be polyphyletic. Lineage I corresponds with the Leiochirus + (Exochirus + Syncampsochirus) + (Eutriacanthus + (Plastus + (japonicus-group of Euleptarthrus + (Barychirus + Stigmatochirus)))) clade and forms a sister group to the genus Thoracochirus Bernhauer. Lineage II corresponds with the Priochirus, s. str. + (Cephalomerus + (longicornis- and malayanus-group of the Euleptarthrus)) clade. In addition, the analysis reveals sister relationships between representatives of Lineage I and the genus Thoracochirus. On the basis of phylogenetic inference, the genus Plastus Bernhauer, stat. nov. is proposed to include the subgenera of Lineage I and a new subgenus Sinumandibulus, subgen. nov., which is erected for the japonicus-group of the former subgenus Euleptarthrus. The genus Priochirus Sharp sensu novo is redefined to include the subgenera of Lineage II. Seven new species are described from China: Plastus (Sinumandibulus) curvaticornis, sp. nov. from Sichuan; Plastus (Sinumandibulus) recticornis, sp. nov. from Hubei; Priochirus (Euleptarthrus) amblyodontus, sp. nov. from Hunan; Priochirus (Euleptarthrus) baoxingensis, sp. nov. from Sichuan, Priochirus (Euleptarthrus) elongates, sp. nov. from Guizhou, Priochirus (Euleptarthrus) parvicornis, sp. nov. from Fujian and Priochirus (Euleptarthrus) oxygonus, sp. nov. from Hainan.

AbstractA phylogenetic analysis of the fungivorous Terebrantia family Merothripidae is performed based on 73 morphological characters and 24 taxa representing the three genera of Merothripidae and outgroups. Heterothrips mexicanus Watson, Heterothripidae; Dorythrips Hood, Melanthripidae; and two genera of Aeolothripidae,Gelothrips Bhatti and Orothrips Moulton represent the outgroup. The Melanthripidae and Aeolothripidae genera are included in order to have a first approximation of the phylogenetic relationships between Merothripidae and these two families (previously suggested to be close relatives). According to the results, the monophyly of Merothripidae is recovered; within Merothripidae, Erotidothrips is the sister group of Damerothrips+Merothrips. Dorythrips is supported as the sister group of Merothripidae, and Aeolothripidae are the sister group to that clade. Additionally, Merothripidae genera are diagnosed and illustrated.
