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.

As currently delimitated, the species-rich mustard tribe Euclidieae DC. (Brassicaceae) comprises 28 genera and 152 species distributed primarily in Asia. To date, no tribe-wide comprehensive phylogenetic analysis has been conducted. In this study, sequence data from the nuclear ribosomal internal transcribed spacer (nrITS) region of 82 species in all 28 genera of Euclidieae were used to test its monophyly and infer inter- and intra-generic relationships within. Phylogenetic analyses revealed thatRhammatophyllumandSisymbriopsisare embedded withinSolms-laubachias.l., andSolms-laubachialanuginosa(Eurycarpuslanuginosus) fell outside the tribe. Therefore,Solms-laubachias.l. as currently recognized is not monophyletic and its generic delimitation needed further study. Besides, our results suggest that the generaLepidostemon,Neotorularia, andTetracmeare polyphyletic.

The females of Oxysoma itambezinho Ram rez and Monapia tandil Ram rez are described for the first time, and new observations are added to a previous dataset for phylogenetic analysis. Oxysoma itambezinho differs from other Oxysoma species by the presence of unmodified copulatory ducts, not encircling the spermathecae. Monapia tandil resembles some Monapia species by the presence of a posteriorly directed pouch on the median epigynal field, unlike its sister species, M. vittata. The resulting phylogenetic trees are the same as previously obtained, but these instances of homoplasy decreased the support for some groups inside Oxysoma and Monapia.

Phylogenetic relationships of the subgroups of Parathalassiinae are presented, based on a morphological cladistic analysis. Worldwide, all known extant genera, species groups and newly discovered undescribed lineages are represented in the analysis. Some previously proposed generic relationships are supported by the analysis, but recognition of many current genera renders the present concept of Microphorella Becker as both paraphyletic and polyphyletic. Microphorella merzi Gatt is here classified in Eothalassius Shamshev & Grootaert, as Eothalassius merzi (Gatt) comb. nov. A preliminary classification with all included extant lineages within the Parathalassiinae (at the genus and species group level) is outlined. The ranking of these lineages is discussed and several species groups of Microphorella may need to be elevated to generic or subgeneric level, whereas some currently recognized genera may need to be relegated to subgenera.

The genus Oecopetalum Greenm. & C.H. Thomps. (Metteniusaceae) is distributed in the southeastern portion of Mexico to Central America (Guatemala, Nicaragua, and Costa Rica). Three species have been described and two have been reported as edible. We studied herbarium specimens of the genus Oecopetalum and performed a phylogenetic analysis based on the chloroplast genes matK and ndhF to answers to main questions: How many species are in the genus Oecopetalum? Is the genus Oecopetalum monophyletic? What are the generic relationships with other members of the family? Oecopetalum is a monophyletic genus with only two species. Pittosporosis is the sister group of Oecopetalum. The Trans-Atlantic relationship of Oecopetalum and Pittosporosis is a recurrent geographic pattern in the family Mettenuisaceae as well as in the family Icacinaceae. Our results, in concordance with fossil evidence and relationships of other groups, support the Boreotropical model of high-latitude terrestrial migrations of tropical taxa during the globally warm Paleocene–Eocene.

The phylogeny of the Elipsocidae is reappraised to aid understanding of generic relationships within the family, leading to its clear definition as a monophyletic entity and clarification of its position within the infraorder Homilopsocidea. Examination of new material and generic-level revision results in descriptions of ten new elipsocid genera: Prionotodrilus, gen. nov. for P. parvus (Smithers & Thornton), comb. nov. and P. serratus (Schmidt & Thornton), comb. nov.; Ausysium, gen. nov. for A. joyceorum, sp. nov.; Diademadrilus, gen. nov. for D. annulatus (Smithers), comb. nov., for which a description of the female is given, and D. masseyi (New), comb. nov.; Euryphallus, gen. nov. for E. badonneli (New & Thornton), comb. nov., E. cinqueportsae (Thornton & New), comb. nov., E. cooki (Thornton & New), comb. nov., E. defoei (Thornton & New), comb. nov., E. selkirki (Thornton & New), comb. nov., E. skottsbergi (Thornton & New), comb. nov. and E. stigmaticus (Tillyard), comb. nov.; Gondwanapsocus, gen. nov. for G. australis, sp. nov.; Onychophallus, gen. nov. for O. diemenensis, sp. nov.; Psocophloea, gen. nov. for P. sarahae, sp. nov.; Telmopsocus, gen. nov. for T. waldheimensis, sp. nov.; Villopsocus, gen. nov. for V. tasmaniensis, sp. nov., and Weddellopsocus, gen. nov. for W. avius (Smithers), comb. nov., W. carrilloi (Thornton & Lyall), comb. nov., W. flavus (Thornton & Lyall), comb. nov., W. griseus (New & Thornton), comb. nov. and W. valdiviensis (Blanchard), comb. nov. A rediagnosis of Spilopsocus is given, the male of Sabulopsocus tractuosus Smithers is described and Nepiomorpha phragmitella Smithers is transferred to Clinopsocus New. We provide a phylogenetic analysis to assess the monophyly of Elipsocidae. Sixty-one characters are scored for 38 taxa, including the putative new genera and four outgroups. Monophyly of Elipsocidae is supported with the exclusion of four genera: Palmicola Mockford is transferred to Mesopsocidae; Sabulopsocus Smithers and Moapsocus, gen.�nov. for M. angelicus, sp. nov. are placed in the new family Sabulopsocidae; and Drymopsocus Smithers, which is the sister-taxon to Elipsocidae, is incertae sedis. Other taxa previously regarded as elipsocids are reassigned: Elipsocus impressus (Hagen), Elipsocus modestus Banks and Elipsocus boops (Hagen) are redescribed and respectively placed in Valenzuela Navás (Caeciliusidae), Dasydemella Enderlein (Dasydemellidae) and Mesopsocus Kolbe (Mesopsocidae). Lesneia Badonnel is placed in the new family Lesneiidae. The position of Eolachesilla Badonnel is discussed briefly. A key to genera and comment on characters diagnosing the family Elipsocidae is presented. We retain two subfamilies and discuss the merits of our proposed higher classification. A brief biogeographical interpretation suggests that the family has a southern origin and may be as old as the Mesozoic.

Bayesian phylogenetic analysis of nuclear ribosomal ITS and ETS confirms earlier results from chloroplast DNA phylogenetic analysis and morphology that support the recent synonymy under Dimerostemma of several species formerly recognized within the genus Angelphytum.  The nine former Angelphytum species we sampled did not form a monophyletic group.  Based on sampling 18 of 29 species Dimerostemma was found monophyletic and derived within Ecliptinae, although its position was not fully resolved among the accessions of 32 other genera of the subtribe.  Our results add several new hypotheses of generic relationships in this group.  Dimerostemma annuum, the only annual species of the genus, resolved sister to all other Dimerostemma.  This with D. bishopii and D. retifolium formed a grade sister to two clades, each containing a combination of Angelphytum and Dimerostemma species.  Species of Dimerostemma that have xylopodia do not form a monophyletic group.  Montanoa of subtribe Montanoinae was sister to the Andean genera Idiopappus, Kingianthus and Monactis and collectively sister to a clade of Ecliptinae with seven subclades based on our sampling.  The genera Kingianthus and Wedelia were not found to be monophyletic.
