One of the many taxonomic challenges found in the Dendropsophus microcephalus species group is the Dendropsophus walfordi distinction from D. nanus. Recent phylogenetic inferences have indicated the paraphyly of these species, although they were not designed to assess this issue. To contribute to the delimitation of these species, we analyzed the 12S, 16S and COI mitochondrial genes, the morphological traits, and the advertisement calls of specimens from northern Amazonia to Argentina, including the type localities of D. nanus and D. walfordi. Paraphyly of D. nanus with respect to D. walfordi was inferred by maximum-parsimony and Bayesian analyses, and five major clades exhibiting nonoverlapping geographic distributions were recognized. The bPTP and ABGD analyses supported the existence of five independently evolving lineages in this complex. Acoustic and morphological data clearly distinguished the clade that included the topotypes of D. walfordi from the others, corroborating the validity of this species. To avoid the paraphyly of D. nanus with respect to D. walfordi, we recognize the clade distributed from central-southern Brazil to Argentina as D. nanus, the clade distributed in Amazonia as D. walfordi, and discuss the existence of unnamed cryptic species closely related to D. nanus and D. walfordi.

DNA molecular data are used to generate a phylogeny for the micropezid subfamily Taeniapterinae. Thirty-two taeniapterine species were sampled, including 10 of the 20 New World genera recognized by Steyskal, as well as one genus formerly treated as a synonym of Poecilotylus Hennig (Hemichaeta Steyskal). Five species from the Micropezinae were included as outgroups. A total DNA dataset of 4705 bp, including mitochondrial genes (12S and cytochrome c oxidase I (COI)) and nuclear coding genes (wingless and CAD), was analysed using maximum parsimony and Bayesian inference. The genus Taeniaptera Macquart was found to be non-monophyletic with respect to the remainder of the Taeniapterini analysed here. Taeniaptera is restricted to the Taeniaptera trivittata Macquart species group, Mitromyia Cresson is resurrected to contain the Taeniaptera grata (Wulp) species group, and Paragrallomyia Hendel is resurrected to contain most species previously considered Taeniaptera. Poecilotylus is recognized as a paraphyletic group awaiting further research.

Abstract A taxonomic revision of all Australian species of Metopia Meigen (Sarcophagidae: Miltogramminae) is completed using an integrated approach combining molecular and morphological data. Metopia nudibasis (Malloch) is redescribed as a species complex and a new endemic Australian species, Metopia sputnik sp. n., is described. Evidence is presented that Metopia sauteri (Townsend) is absent from Australia and this species is therefore removed from the known Australian fauna. Molecular phylogenetics is used to reconstruct interspecific and generic relationships and support morphology-based species hypotheses. Phylogenetic analysis splits Metopia Meigen into two clades, separated by Aenigmetopia Malloch, rendering the former genus nonmonophyletic. The implications of this are discussed.

The Status

The type genus of Serpulidae, Serpula Linnaeus, 1758, along with closely related genera Crucigera Benedict, 1887 and Hydroides Gunnerus, 1768, accounts for approximately one-third of all described species in the family. Although previous morphological and molecular studies unequivocally indicate that these three genera constitute a monophyletic group, the status of each genus remains unknown. In this study, the relationships among and within the genera Serpula, Crucigera, and Hydroides were investigated using maximum parsimony and Bayesian analyses of nuclear (18S and 28S rDNA) and mitochondrial (cytochrome b) genomic molecular markers plus morphology. The phylogeny supports the monophyly of Hydroides, but Serpula forms a paraphyletic basal grade and Crucigera is polyphyletic. The lack of close relationship between Hydroides and Crucigera indicates that their similar opercular features are not homologous.

Abstract Anthropogenic environmental change is leading to changes in distribution for many organisms. While this is frequently discussed for prominent organisms of high conservation value, the same is true for the many cryptic species that rarely figure in debates on the human impact. One such cryptic taxon is the European Ptomaphagus sericatus (Chaudoir, 1845) and related forms. During a citizen science expedition in the Vondelpark, Amsterdam, the Netherlands, we obtained two forms of this species complex. We placed the examination of these specimens in the context of a re-analysis of the species group, and, using DNA barcoding and genital study on material collected thoughout Europe, found that the P. sericatus species complex consists of three distinct, partly sympatric species, one of which was previously undescribed. On the basis of collection data, at least two species, P. medius and P. thebeatles sp. n., show signs of having recently undergone (possibly anthropogenic) range changes, with P. medius even reaching North America. We describe P. thebeatles sp. n.; we raise two subspecies, viz. P. sericatus sericatus (Chaudoir, 1854) and P. sericatus medius (Rey, 1889) to the level of species, and designate a neotype for the former; we identify P. dacicus Jeannel, 1934 and P. pyrenaeus Jeannel, 1934 as junior synonyms of P. sericatus, and P. compressitarsus (Rey, 1889) as a junior synonym of P. subvillosus Goeze, 1777; we identify P. septentrionalis Jeannel, 1934 and P. miser (Rey, 1889) as junior synonyms of P. medius; we designate lectotypes for P. medius and P. miser.

AbstractThe taxonomy of Merodon dobrogensis Bradescu, 1982 (Diptera: Syrphidae) species subgroup was reviewed. Multiple data sources (morphology, geometric morphometry of wings and surstylus, molecular data, and distributional data) were used to investigate the species subgroup in the manner of integrative taxonomy. Merodon dobrogensis Bradescu, 1982 and M. puniceus Vujić, Radenković, and Pérez-Bañón, 2011 are supported as distinct species belonging to the M. dobrogensis species complex within the M. dobrogensis species subgroup. Additionally, evidence is presented for the description of a new species, M. rojoi Radenković and Vujić new species, with a distribution in mainland Greece, the Greek island Euboea, and the Peloponnese. A short diagnosis is provided for the M. aureus species group, the M. dobrogensis species subgroup, and the newly defined M. dobrogensis species complex, in addition to a description of the new species, with drawings and photographs of adult morphology.

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

Margyricarpus pinnatus is a poorly understood entity from natural grasslands of South America that it better considered as a species complex. In this work we contribute to the advancement of the taxonomic knowledge of this challenging species complex by describing two new species of Margyricarpus from southern Brazil. We present field photographs, illustrations, a distribution map and ecologic and conservation notes on the new species.
