A phylogenetic revision of the true bug genus Heraeus (Hemiptera: Rhyparochromidae: Myodochini), with the description of two new genera and 30 new species

Prior to this study, the genus Heraeus Stål, 1862 included 14 species, all of which are restricted to the Western Hemisphere. Three species are known from the Nearctic Region, nine from the Neotropical Region, and two mainly tropical elements are distributed in both regions. In this contribution, we consider Heraeus cincticornis Stål, 1874 a junior synonym of Heraeus elegans (Walker, 1873), select a lectotype for Heraeus coquilletti Barber, 1914, and neotype for Lygaeus triguttatus Guérin‐Méneville, 1857, and describe 28 new species. In addition, the two new genera, Baranowskiobius gen. nov., to include H. elegans (Baranowskiobius elegans comb. nov.) and two new species, and Paraheraeus gen. nov., to include Heraeus eximius Distant, 1882 (Paraheraeus eximius comb. nov.), are described. Previously described species and new taxa are (re)described and illustrated, including male genitalia. Scanning electron micrographs, general habitus photographs, and distribution maps are included for all species studied. A phylogenetic analysis comprising 46 terminal taxa and 50 morphological characters was performed, and five species groups were hypothesized, including the coquilletti, caliginosus, guttatus, illitus, and plebejus groups. All known species of Heraeus and the new genera are included in the phylogenetic analysis. The type species of the genera Myodocha Latreille, 1807, Orthaea Dallas, 1852, and Paisana Dellapé, 2008 are used as out‐groups.     

Review of the stiletto fly genus Actenomeros Winterton & Irwin (Diptera, Therevidae, Agapophytinae)

Systematics of Schistopterini (Diptera: Tephritidae: Tephritinae), with descriptions of new genera and species

Abstract. The systematics of tribe Schistopterini (Diptera: Tephritidae) is reviewed and discussed, and a key is given to the fourteen current genera, of which four are new. A cladogram of the type species of the genera plus all other species of one of the new genera ( Microtreta ) is presented, supporting the monophyly of Microtreta .
The new genera include Calloptera (type species Rhabdochaeta asteria Hendel), Microtreta (type species Microtreta fini , sp.n.), Melanopterella (type species Rhabdochaeta nigra Bezzi) and Schistotephritis (type species Camaromyia acrophthalma Bezzi). Microtreta is treated comprehensively; its constituents, deemingi, fini, frontale, jeffreyi and longicornis (all new species), are described from East Africa and the Arabian Peninsula. Host plants, all of genus Vernonia (Asteraceae), are recorded for the four East African species. Characters of immature stages are described for M. longicornis . Eighteen new combinations are made.     

A revision of the Australian earthworm genus Woodwardiella with descriptions of two new genera (Megascolecidae: Oligochaeta)

The genus Woodwardiella Stephenson, 1925, from which oriental species were excluded by Gates (1938, 1939, 1960), is further restricted to include only five south-western Australian species, a Tasmanian species and provisionally, as species inquirenda , the Victorian W. healesi (Michaelsen, 1923) and a further Tasmanian species, W. mortoni Spencer, 1895.
Twelve species originally assignable to Woodwardiella , of which one is reduced to a junior synonym, constitute a new genus, Heteroporodrilus , known only from the southeastern portion of the Australian mainland.
Woodwardiella punctatus (Spencer, 1900) is shown to be a junior synonym of the sympatric Victorian W. smithi (Fletcher, 1889a) which is placed in the new monotypic genus Pseudoperichaeta.
Plutellus manifestus (Fletcher, 1889), which has tubular prostates and belongs to the family Acanthodrilidae s. Gates, shows close affinities with Heteroporodrilus which is referable to the family Megascolecidae s. Gates, characterized by racemose prostates. Variation in the form of the prostates can no longer be accorded even subfamilial significance and Plutellus is transferred to the subfamily Megascolecinae. Close morphological similarity demonstrated between P. manifestus and P. heteroporus Perrier, 1873, the type species of the genus, suggests a basis for restriction of the heterogeneous assemblage known as Plutellus.
Diporochaeta davallia Spencer, 1900, has close affinities with Pseudoperichaeta and, like this genus, has tufted meronephridia anteriorly.     

Revision of some comasterid genera from Australia (Echinodermata: Crinoidea), with descriptions of two new genera and nine new species

Morphological characters used in comasterid taxonomy are reappraised. As a result, form and distribution of pinnule combs are newly promoted as primary characters of generic recognition. Form and arrangement of cirri and division series, as used by A. H. Clark (1931), are rejected as characters important in recognizing taxa higher than species. Five of 12 comasterid genera reported as occurring in Australian waters (H. L. Clark, 1946) are critically examined. Of these genera, Comantheria A. H. Clark, 1909b is referred to the synonymy of Comanthus A. H. Clark, 1908a, Comanlhoides A. H. Clark, 1931 is referred to the synonymy of Cenolia A. H. Clark, 1916b, and Comanthina A. H. Clark, 1909b is maintained. In addition, two new genera are described. These genera are related by the occurence of the first brachial syzygy at 3 + 4 on all arms. Twenty-six species within the five genera are now recognized in Australian waters. Nine new species are described, and the 17 existing species are rediagnosed and critically reappraised. The revision involves taxa distributed throughout the Indo-west Pacific region, as far west as S Africa.     

Phylogenetic revision of Agapophytinae subf.n. (Diptera: Therevidae) based on molecular and morphological evidence

Agapophytinae subf.n. is a highly diverse lineage of Australasian Therevidae, comprising eight described and two new genera: Agapophytus Guérin‐Méneville, Acupalpa Kröber, Acraspisa Kröber, Belonalys Kröber, Bonjeania Irwin & Lyneborg, Parapsilocephala Kröber, Acatopygia Kröber, Laxotela Winterton & Irwin, Pipinnipons gen.n. and Patanothrix gen.n. A genus‐level cladistic analysis of the subfamily was undertaken using sixty‐eight adult morphological characters and c. 1000 base pairs of the elongation factor‐1α (EF‐1α) protein coding gene. The morphological data partition produced three most parsimonious cladograms, whereas the molecular data partition gave a single most parsimonious cladogram, which did not match any of the cladograms found in the morphological analysis. The level of congruence between the data partitions was determined using the partition homogeneity test (HT_F) and Wilcoxon signed ranks test. Despite being significantly incongruent in at least one of the incongruence tests, the partitions were combined in a simultaneous analysis. The combined data yielded a single cladogram that was better supported than that of the individual partitions analysed separately. The relative contributions of the data partitions to support for individual nodes on the combined cladogram were investigated using Partitioned Bremer Support. The level of support for many nodes on the combined cladogram was non‐additive and often greater than the sum of support for the respective nodes on individual partitions. This synergistic interaction between incongruent data partitions indicates a common phylogenetic signal in both partitions. It also suggests that criteria for partition combination based solely on incongruence may be misleading. The phylogenetic relationships of the genera are discussed using the combined data. A key to genera of Agapophytinae is presented, with genera diagnosed and figured. Two new genera are described: Patanothrix with a new species (Pat. skevingtoni) and Pat. wilsoni (Mann) transferred from Parapsilocephala, and Pipinnipons with a new species (Pip. kroeberi). Pipinnipons fascipennis (Kröber) is transferred from Squamopygia Kröber and Pip. imitans (Mann) is transferred from Agapophytus. Agapophytus bicolor (Kröber) is transferred from Parapsilocephala. Agapophytus varipennis Mann is synonymised with Aga. queenslandi Kröber and Aga. flavicornis Mann is synonymised with Aga. pallidicornis (Kröber).     

Phylogenetic affinities of Auriculostoma (Digenea: Allocreadiidae), with descriptions of two new species from Peru

Two new allocreadiid trematodes are described from the intestine of characid fishes from Rio Itaya, a tributary of the Amazon River near Iquitos, Peru. Auriculostoma foliaceum n. sp. is described from Bryconops cf. caudomaculatus (Günther, 1864) Backup, 2003, and Auriculostoma diagonale n. sp. from Stethaprion cf. erythrops Cope, 1870. Auriculostoma foliaceum n. sp. differs from its congeners by having a foliated lateral margin and lacking vitelline follicles in the forebody. Auriculostoma diagonale n. sp. differs from all of its congeners except Auriculostoma platense (Szidat, 1954) Scholz, Aguirre-Macedo, and Choudhury, 2004, by having oblique rather than tandem testes and differs from A. platense by having a much more elongated cirrus sac. Phylogenetic hypotheses based on analyses of 3 alignments of partial sequences of the 28S rDNA gene conducted in this study provide a framework for revaluating the classification of Allocreadiidae Looss, 1902. The present analyses show that (1) Paracreptotrematina limi Amin and Myer, 1982, does not belong in the Allocreadiidae; (2) Creptotrematina aguirrepequenoi Jiménez-Guzmán, 1973 (spelled here without diacritic mark), does not belong to Paracreptotrematina Amin and Myer, 1982, but remains in the Allocreadiidae; (3) Auriculostoma astyanace Scholz, Aguirre-Macedo, and Choudhury, 2004, is closely related to C. aguirrepequenoi and Wallinia chavarriae Choudhury, Hartvigsen-Daverdin, and Brooks, 2002; (4) Megalogonia Surber, 1928, is retained as an accepted genus in the Allocreadiidae; and (5) Margotrema Lamothe-Argumedo, 1970, is found to be nested among 3 species of Crepidostomum Braun, 1900.     

Revision of the Chinese species of Dialineura Rondani, 1856 (Diptera,Therevidae, Therevinae)

Two species, Dialineura nigrofemorata Kröber and Dialineura gorodkovi Zaitzev, are recorded from China for the first time. The female information of Dialineura henanensis Yang is also included here. A key to all the male species in the world and a biogeography map of China are presented.     

The Turkish Agromyzidae (Diptera), with descriptions of four new species

A total of 117 agromyzid leafminers are known to occur in Turkey, among which Agromyza phylloposthia, Pseudonapomyza pyriformis, Liriomyza cardariae and Phytomyza geminata are described as new to science. A faunistic account of the Agromyzidae in Turkey is given.     

Phylogenetic relationships within the superfamily Desmodoroidea (Nematoda: Desmodorida), with descriptions of two new and one known species

Three nematode species of the superfamily Desmodoroidea Filipjev, 1922, were isolated from beach sediments in Wellington, New Zealand, for morphological and molecular analyses. Two of these species, D esmodorella verscheldei sp. nov. and D racograllus ngakei sp. nov. , were new to science and are described herein. Epsilonema rugatum Lorenzen, 1973, comb. nov. , which was originally described from New Zealand material as a subspecies of Epsilonema dentatum from Chile, is redescribed and elevated to the rank of species based on cuticular ornamentation. The phylogenetic relationships amongst the three Desmodoroidea families are investigated based on new and existing sequences of the D2 and D3 expansions segments of large subunit (LSU) 28S rRNA gene and small subunit (SSU) of 18S rDNA gene. Our analyses suggest that the Draconematidae is a sister taxon to the Desmodorinae and Spiriniinae, with the Draconematidae forming a monophyletic crown group and the Desmodorinae and Spiriniinae forming a paraphyletic stem group. Phylogenetic relationships between the Epsilonematidae and Stilbonematinae, however, could not be determined with certainty. The SSU and D2‐D3 of LSU consensus trees indicate that the morphological resemblance between the Draconematidae and Epsilonematidae, which are both characterized by swollen pharyngeal body regions and mid‐posterior body regions with specialized setae, reflects distinct and independently evolved adaptations to their unusual mode of locomotion, with differences in the structure and distribution of specialized setae between the two families also consistent with convergent evolution. We show that the family Desmodoridae and superfamily Desmodoroidea as currently defined are not monophyletic. It was not possible to determine whether the Prodesmodorinae are more closely related to the Desmodoroidea or Microlaimoidea, although it is clear that they do not belong to the Desmodoridae. The single Molgolaiminae sequence available formed a distinct clade together with the superfamily Microlaimoidea, and should therefore be placed with the latter. Clarifying the phylogenetic relationships within the Desmodoroidea will require greater focus on the Pseudonchinae, Molgolaiminae, and Epsilonematidae, for which no or very few sequences are available at present. © 2016 The Linnean Society of London

Redefinition of the Glyptonsternine genus Pareuchiloglanis (Teleostei: Sisoridae), with descriptions of three new genera

The genus Pareuchiloglanis (Sisoridae) contains 20 valid species and 5 species with uncertain taxonomic status. Previous morphological and molecular studies indicated that Pareuchiloglanis was non-monophyletic; nonetheless, no change was made to correct the taxonomy of the genus. Therefore, the authors conducted a systematic morphological comparison and molecular phylogenetic study on Pareuchiloglanis. The results showed that Pareuchiloglanis is a polyphyletic group. Species previously identified as Pareuchiloglanis can be divided into four groups, of which Pareuchiloglanis poilanei alone has the genus name Pareuchiloglanis. The remaining three groups of species are contained within new genera named Barbeuchiloglanis, Sineuchiloglanis and Tremeuchiloglanis. Each genus has a distinct distribution that does not cross or overlap. The molecular results supported the reliability of morphological classification and indicated that the four genera were not directly related to one another. Specifically, Sineuchiloglanis and Tremeuchiloglanis shared no recent common ancestor. In contrast, Sineuchiloglanis formed a sister group with Chimarrichthys, and Tremeuchiloglanis formed a sister group with Creteuchiloglanis and Pseudexostoma.     

New Asellota from the Antarctic deep sea (Crustacea, Isopoda, Asellota), with descriptions of two new genera

Two new genera, Reductosoma gen.n. (Desmosomatidae) and Desmostylis gen.n. (Desmosomatidae), and five new species are described from the Maud Rise and the Gunnerus Ridgc, Antarctica. Two new species of the Desmosomatidae (Eugerdellatinae and Desmosomatinae) are described: Reduetosoma gunnera gen. et sp.n. and Desmosoma hesslera sp.n.; one species of the Munnopsidae (Eurycopinae), Disconectes colernuni sp.n.; and two species of the Macrostylidae from the Antarctic deep sea, Desmostylis obscurus gen. et sp.n. and Macrostylis sarsi sp.n. Comments on the phylogeny and zoogeography are given.
