Generic Relationships

With discovery of four new Neotropical species, the New World shore-fly genus Rhysophora Cresson, 1924 is revised, including a phylogenetic reassessment of some generic relationships within Discomyzini and of species within Rhysophora. The reconstructed phylogenetic relationships are based on 43 adult morphological characters and resulted in the following discoveries, mostly based on the well-supported cladogram: (1) the monophyly of Rhysophora is corroborated; (2) its sister group is Helaeomyia Cresson, not Guttipsilopa Wirth, as previously proposed; (3) three species groups within Rhysophora are recognized; and (4) greater species diversity is in South America, where there is also greater diversity in host plants. We hypothesise that the two Nearctic species, R. robusta and R. laffooni, resulted from two independent dispersal and speciation events when their water lettuce and pickerel weed hosts also dispersed there from the Neotropics. All of these flies are associated with aquatic plants of the families Pontederiaceae (Pontederia, Eichhornia) and Araceae (Pistia stratiotes), with the exception of R. griseola. All species are redescribed and an identification key, distribution maps and illustrations of male terminalia are provided to assist identification of these species.

We review forty-five species of Nepticulidae (Lepidoptera) based on an analysis of samples collected in the central Andean region of Peru and Bolivia. Thirteen of these species are new to science, and are named and described here: Stigmella paracosma Remeikis & Stonis, sp. nov., S. expressa Remeikis & Stonis, sp. nov., S. acalyphae Diškus & Stonis, sp. nov., S. lepida Diškus & Stonis, sp. nov., S. misera Diškus & Stonis, sp. nov., S. inca Diškus & Stonis, sp. nov., S. eiffeli Diškus & Stonis, sp. nov., S. arequipica Remeikis & Stonis, sp. nov., S. coronaria Diškus & Stonis, sp. nov., S. azulella Diškus & Stonis, sp. nov., S. sparsella Diškus & Stonis, sp. nov., Manoneura forcipis Diškus & Stonis, sp. nov., and Acalyptris murex Diškus & Stonis, sp. nov. Some of the central Andean species are recorded here as leaf-miners on Euphorbiaceae (Acalypha), Fabaceae (Collaea), Rosaceae (Polylepis), Malvaceae (Sida), Calceolariaceae (Calceolaria), Lamiaceae (Clinopodium), and Asteraceae (Ageratina and Trixis). We create eleven new species groups based on morphological characters designated in Stigmella and one in Acalyptris. A pictorial key to the species groups and distribution maps are provided. All new species are illustrated with 150 photographs and drawings of the adults and genitalia, and, where known and/or available, photographs of host-plants and leaf-mines.

Maximum Likelihood Phylogeny

Abstract A northward trans-Wallacean radiation is demonstrated for Chrysorthenches, a member of the Orthenches group. Here we review Chrysorthenches and allied genera resulting in a generic transfer of Diathryptica callibrya to Chrysorthenches and two new congeners: C. muraseaeSohn & Kobayashisp. nov. from Japan and C. smaragdinaSohnsp. nov. from Thailand. We review morphological characters of Chrysorthenches and allied genera, and find polyphyly of Diathryptica and the association of the Orthenches-group with Glyphipterigidae. These findings were supported in a maximum likelihood phylogeny of DNA barcodes from ten yponomeutoids. We analysed 30 morphological characters for 12 species of Chrysorthenches, plus one outgroup, via a cladistic approach. The resulting cladogram redefined two pre-existing Chrysorthenches species-groups and identified one novel lineage: the C. callibrya species-group. We review the host associations between Chrysorthenches and Podocarpaceae, based on mapping the working phylogenies. Our review suggests that ancestral Chrysorthenches colonized Podocarpus and later shifted to other podocarp genera. Biogeographical patterns of Chrysorthenches show that they evolved long after the Podocarpaceae radiation. Disjunctive trans-Wallacean distribution of the C. callibrya species-group is possibly related to the tracking of their host-plants and the complicated geological history of the island-arc system connecting Australia and East Asia.

First Time

Hypoxys is one of four subgenera of Edessa (Fabricius, 1787) together with Aceratodes (De Geer, 1773), Dorypleura (Lepeletier & Serville, 1825) and Edessa (Fabricius, 1787). This taxon has a very confusing taxonomy due to incorrect use of the names available, imprecise descriptions, and large number of very similar species. To illustrate the confusion, Hypoxys potentially includes a large number of species of Edessa, but actually contains only the type species, according to the most recent catalogue. The name E. quadridens Fabricius, 1803, type species of Hypoxys, was used for more than a century as a label to identify a large group of similar species. In this work we continue revising Edessa elevating Hypoxys to genus based on the following morphological characters: proximal part of costal margin black; evaporatorium with a deep notch on lateral margin; anterior arms of metasternal process acuminate; pygophore longer than wide and subrectangular or barrel-shaped in dorsal view; dorsal rim of pygophore well-projected, almost reaching posterolateral angles and finishing in a small lobe; and posterolateral angles of pygophore not developed. Hypoxys is being divided in four species groups to include 17 species transferred from Edessa. H. quadridens group comprises: Hypoxys quadridens (Fabricius, 1803) (type species), H. boerneri (Breddin, 1904) comb. nov., H. claricolor (Breddin, 1907) comb. nov., H. dolosus (Breddin, 1907) comb. nov., H. eburatulus (Breddin, 1907) comb. nov., H. necopinatus (Breddin, 1907) comb. nov., H. offuscatus (Breddin, 1907) comb. nov. and H. trabeculus (Breddin, 1907) comb. nov. H. triangularis group comprises: H. triangularis (Dallas, 1851) comb. nov. (type species), H. capito (Breddin, 1904) comb. nov. and H. subrastratus (Bergroth, 1891) comb. nov. H. oxyacanthus group comprises: H. oxyacanthus (Breddin, 1904) comb. nov. (type species), H. brachyacanthus (Breddin, 1904) comb. nov., H. infulatus (Breddin, 1904) comb. nov., H. leptacanthus (Breddin, 1904) comb. nov. and H. tragelaphus (Breddin, 1903) comb. nov. H. balteatus group comprises only H. balteatus (Walker, 1868) comb. nov. These groups of species will be useful to organize the new species of Hypoxys that will be described in upcoming papers. Descriptions, measurements, photos of genitalia of both sexes; photos in dorsal and ventral views of the species; and distribution maps are provided. Males of H. capito, H. claricolor, H. eburatulus, H. infulatus, and H. subrastratus are described for the first time. Female of H. necopinatus is described for the first time. Edessa jugalis is considered a junior synonym of H. quadridens; E. rimata a junior synonym of H. offuscatus; E. scabriventris and E. leprosula junior synonyms of H. triangularis; E. pachyacantha a junior synonym of H. tragelaphus; E. orba a junior synonym of E. oxyacanthus. A key to the species of Hypoxys is also provided.

The Indo-Australian crowned weevil genus Asytesta Pascoe, 1865 is revised. Forty-one species are recognized, including18 that are new: A. alexandriae, A. alexriedeli, A. allisoni, A. biakana, A. cheesmanae, A. concolora, A. emarginata, A.fayae, A. frontalis, A. gressitti, A. julieae, A. marginalis, A. morobeana, A. sedlaceki, A. thompsoni, A. tuberculata, A.vivienae, and A. woodlarkiana, new species. One subspecies, A. lugubris bidentata Voss is elevated to species status, A.bidentata Voss, new status. Four species are newly synonymized: A. circulifera Lea, 1928 = A. rata Heller, 1910, A.definita Faust, 1898 = A. humeralis Pascoe, 1865, A. granulifera Lea, 1928 = A. aucta Faust, 1898, and A. setipes Lea,1928 = A. lugubris Heller, 1895 new synonyms. Six new species groups are proposed. Lectotypes are designated for 18species. Two species are transferred from Asytesta to other genera: A. maura Pascoe to Microporopterus Lea and A.ypsilon Heller to Meroleptus Faust, new combinations. A checklist and key for all crowned weevil genera, key to speciesgroups and species of Asytesta, adult habitus illustrations, distribution maps, and line drawings of diagnostic charactersare provided.A phylogeny for the genus based on 82 adult morphological characters (187 states) for 41 ingroup taxa is alsopresented. All genera and species of the crowned weevil group as redefined here (including Cyamomistus Heller,Eudyasmus Pascoe, Glochinorhinus Waterhouse, Nothotragopus Zimmerman, Panopides Pascoe, and Zygara Pascoe),were included in the analysis to test the monophyly of Asytesta. Monophyly of Asytesta was supported only with thesynonymy of the monotypic genus Zygara. Accordingly, Zygara is a new junior synonym of Asytesta and Zygara doriae (Kirsch) is returned to its original combination with Asytesta; A. doriae Kirsch resurrected status.

AbstractThe subfamily Panchaetothripinae, comprising 35 genera and 98 species, includes several pest species of which the most notorious is the greenhouse thrips, Heliothrips haemorrhoidalis. In an attempt to establish the sister-group of Heliothrips, the relationships of this genus to 31 of the other genera in the subfamily were examined cladistically, using 35 parsimony-informative morphological characters. The analysis indicated that there was no support for two of the three tribes into which this subfamily is customarily arranged, the Monilothripini and the Panchaetothripini, but weak support for the tribe Tryphactothripini. No clear sister-group relationship could be identified for the New World genus Heliothrips, although it grouped with three old world genera Australothrips, Retithrips and Rhipiphorothrips. It is concluded that a morphological data set is not capable of producing a robust phylogeny of the Panchaetothripinae, and that the subject requires re-examination using molecular data.

Complete Mitochondrial Genomes

Tenthredinidae represents one of the external feeders of the most diverse superfamily, Tenthredinoidea, with diverse host plant utilization. In this study, four complete mitochondrial genomes (mitogenomes), those of Cladiucha punctata, Cladiucha magnoliae, Megabeleses magnoliae, and Megabeleses liriodendrovorax, are newly sequenced and comparatively analyzed with previously reported tenthredinid mitogenomes. The close investigation of mitogenomes and the phylogeny of Tenthredinidae leads us to the following conclusions: The subfamilial relationships and phylogenetic placements within Tenthredinidae are mostly found to be similar to the previously suggested phylogenies. However, the present phylogeny supports the monophyly of Megabelesesinae as a subfamily, with the sister-group placement of Cladiucha and Megabeleses outside of Allantinae. The occurrence of the same type of tRNA rearrangements (MQI and ANS1ERF) in the mitogenomes of Megabelesesinae species and the presence of apomorphic morphological characters also provide robust evidence for this new subfamily. The divergence and diversification times of the subfamilies appear to be directly related to colonization of the flowering plants following the Early Cretaceous. The origin time and diversification patterns of Megabelesesinae were also well matched with the divergence times of their host plants from Magnoliaceae.

The Old World water scavenger beetle genus Sternolophus Solier is revised. Six new species are described: Sternolophus acutipenis sp. n., S. insulanus sp. n., S. jaechi sp. n., S. mandelai sp. n., S. prominolobus sp. n. and S. solitarius sp. n. Three taxa are reinstated as valid species: Sternolophus angustatus (Boheman), S. elongatus Schaufuss and S. mundus (Boheman). The subgenera within the genus are rejected and Neosternolophus Zaitzev syn. n. is synonymized with Sternolophus s. str. Lectotypes are designated for Hydrophilus angolensis Erichson, H. angustatus, H. rufipes Fabricius, Sternolophus brachyacanthus Régimbart, S. comoriensis Fairmaire, S. elongatus, S. frater Schaufuss, and S. rufipes var. foveoliceps Kolbe. On the basis of similar morphological characters, two species-groups are proposed for some of the species within the genus: The angolensis group including S. angolensis, S. inconspicuus (Nietner), S. mundus, and S. solitarius, and the solieri group including S. angustatus, S. elongatus, S. mandelai, S. rufipes Fabricius, and S. solieri Castelnau. Sternolophus unicolor (Castelnau) is considered a nomen dubium. Male genitalia and other diagnostic morphological characters are illustrated, and distribution maps are presented for all 17 species.

The genus <em>Canthyporus</em> Zimmermann, 1919, is revised. A total of 35 species are recognized, all of them distributed within the Ethiopian Region, and with a centre of diversity in the South African Western Cape province. Descriptions of all species are given together with illustrations of habitus and male and female genitalia. A key to species (males), distribution maps, and ecological information are provided. Four new species are described from South Africa: <em>Canthyporus aenigmaticus</em> n.sp., <em>C</em>. <em>nimius</em> n.sp., <em>C. turneri</em> n.sp., and <em>C. wewalkai</em> n.sp. The species <em>C. congener</em> Omer-Cooper, 1956, is regarded as valid and not as a junior synonym of<em> C. canthydroides</em> (Régimbart, 1895). Lectotypes are designated for the following ten names:<em> C. alvei</em> Omer-Cooper, 1965, <em>C. consuetus </em>Omer-Cooper, 1965, <em>C. latus</em> Omer-Cooper, 1965, <em>C. lowryi </em>Omer-Cooper, 1965, <em>C. nebulosus</em> Omer-Cooper, 1965, <em>C. similator</em> Zimmermann, 1923, <em>C. simulator</em> Guignot, 1959, <em>C. testaceus</em> Zimmermann, 1923, <em>Hydroporus collaris</em> Boheman, 1848, and <em>Hydroporus hottentottus</em> Gemminger &amp; Harold, 1868. A parsimony analysis based on 32 morphological characters found 28 shortest trees. Monophyly of the genus <em>Canthyporus</em> is supported mainly by the presence of an anterior ligula on the ventral side of the elytron. Four species groups are recognized within the genus: (1) <em>canthydroides</em> group, including ten species in Namibia and South Africa; (2) <em>exilis</em> group, including four species in Lesotho and South Africa; (3) <em>hottentottus</em> group, including 18 species from the Democratic Republic of the Congo, Ethiopia, Kenya, Lesotho, Madagascar, South Africa, Swaziland, Tanzania, and Zimbabwe; and (4) <em>lateralis</em> group, including three species from South Africa.
