AbstractTeleiopsis, a Holarctic though predominantly Palaearctic genus, is revised and eleven species are recognized. Three of these are newly described and one new generic combination is established. Keys to the species of Teleiopsis and figures of moths and their male and female genitalia are given. A cladistic analysis was carried out using PAUP (Phylogenetic Analysis Using Parsimony); the results are discussed and a consensus classification of the species is derived. Biological data, as far as known, are given for each species. Host-plant and biogeographical relationships within the genus are analysed and factors influencing intraspecific variation are discussed.

Species Groups

Zethus is the largest genus in Eumeninae, with over 250 species. Currently, it is divided in four subgenera: Z. (Zethus), Z. (Zethusculus), Z. (Zethoides) and Z. (Madecazethus). Z. (Zethoides), with 42 species, is subdivided in eight species groups, each considered a phylogenetic unit, that were created without any phylogenetic analysis. Eighteen species of Z. (Zethoides) corresponding to different groups were examined, altogether with terminals from distinct lineages of Zethus, Zethini and Eumenini, to perform a cladistics analysis to verify the proposed divisions. Zethus (Zethoides) and all of its species groups, except for the Z. biglumis group, were monophyletic. Zethus s.s. was paraphyletic in relation to Z. (Madecazethus), Z. (Zethoides) and Ctenochilus. Z. (Zethusculus) was also retrieved paraphyletic. Despite the subgeneric incongruences, the outgroups were too poorly represented to carry a taxonomic modification. Thus, the only alteration was the inclusion of the Z. clypearis group in the Z. biglumis group.

Preliminary Phylogenetic Analysis

AbstractThe subgenus M. (Scaphigenia) Lacordaire includes six species distributed in arid regions of South America. A systematic revision of this subgenus is presented, including re-descriptions and an update of distribution data of the six species. A preliminary cladistic analysis is performed to test the relationships among the species of the subgenus and if the morphological characters used are suitable. A key is presented to separate the seven subgenera of Megalostomis Chevrolat as well as a key for the species of the subgenus M. (Scaphigenia). Male aedeagus internal sac of the nine studied taxa are described and illustrated. This constitutes the first internal sac descriptions for members of this subtribe and could help clarify the homology of such structures within Cryptocephalinae. M. (S) consimilis Achard is reassigned to the species status on the base of genitalic characters. The cladistic analysis was done using forty-one characters from adult external morphology and male and female genitalia. Two species of two different subgenera of Megalostomis: M. (Megalostomis), and M. (Heterostomis) Lacordaire, and one representative of the genus Themesia Lacordaire were selected as out groups. Results were obtained by implicit enumeration using parsimony software. Three equally parsimonious trees were obtained of 45 steps, Ri=0.952, and Ci= 0.941. Support of each group was evaluated by Jacknifing, Bootstrap and Bremer values. Relationships between species are discussed.

PionosyllisMalmgren, 1867 is revised based on a cladistic analysis of the 41 species considered herein as valid, two newly described species in this paper (Basidiosyllis victoriaeandOpisthodonta russelli), 11 species from other genera actually belonging, or related to,Pionosyllis, and 13 syllid species from different subfamilies. The phylogenetic analysis is based on 55 characters; a strict consensus of 1200 equally parsimonious trees (length = 314 steps) was obtained. The clades containing species usually included withinPionosyllisare newly named within the frame of a new Linnean classification of the group (except for one, belonging to another subfamily). The diagnosis ofPionosyllisis emended, and five new genera are proposed:Synmerosyllis,Basidiosyllis,Westheidesyllis,PerkinsyllisandBrevicirrosyllis.ParaehlersiaSan Martín, 2003, proved to be closely related toPionosyllis. Seven species are transferred toOpisthodontaLangerhans, 1879, here emended, and three transferred toNudisyllisKnox & Cameron, 1970 (according to San Martín & Hutchings, 2006).Opisthodonta uraga(Imajima, 1966) comb. nov. andPerkinsyllis longisetosacomb. nov. are redescribed.Pionosyllis compactaMalmgren, 1867,P. styliferaEhlers, 1913,P. giganteaMoore, 1908,P. enigmatica(Wesenberg-Lund, 1950), andNudisyllis magnidens(Day, 1953) comb. nov., are redescribed.Pionosyllis marquesensisMonro, 1939 andP. proceraHartman, 1965 likely belong to the Syllinae, thus they are not treated in the taxonomic account.

A phylogenetic analysis was used to determine evolutionary relationships within the Early Cambrian superfamily Olenelloidea Walcott, 1890. Phylogenetic patterns within the suborder Olenellina Walcott, 1890, which contains the Olenelloidea and the Fallotaspidoidea Hupé, 1953, are also discussed. The Olenelloidea are monophyletic, and synapomorphies uniting them include the condition of the ocular lobes where they intersect the frontal lobe of the glabella, and the condition of the lateral margins of the glabellar lobes. In contrast, taxa formerly assigned to the Fallotaspidoidea are shown to represent a paraphyletic grade of several genera, some more closely related to the Olenelloidea, and some more closely related to the Redlichiina Richter, 1933. Seventy-nine exoskeletal characters were coded for 26 taxa within the Olenellina. These included 22 ingroup Olenelloidea and four outgroup taxa that have traditionally been assigned to the Fallotaspidoidea. When subjected to parsimony analysis these character data yielded a single most parsimonious cladogram that provides an hypothesis of relationship for the generic clades within the superfamily. Two new genera are recognized herein, Fritzolenellus and Lochmanolenellus. It has been argued that genetic flexibility was so great and trilobite morphology was so plastic in the Early Cambrian that suprageneric classification of Early Cambrian trilobites is precluded. Although levels of intraspecific variability may have been slightly higher in the Early Cambrian relative to the mid Paleozoic, based on the extent of polymorphic character codings, it was not so high as to obviate attempts at recovering phylogenetic structure in a major clade of Early Cambrian taxa. In addition, the consistency index recovered by this analysis is not unduly low for a phylogenetic database of this size. The phylogenetic analysis also has bearing on patterns of allometric heterochrony, which have often been held to be significant in Early Cambrian trilobites. The paedomorphic retention of advanced genal spines into the adult probably evolved at least four times. Three of the episodes can be best described as neoteny, the fourth, as progenesis. Finally, based on the phylogeny, it is likely that rates of speciation in trilobites may have been two to three times higher in the Early Cambrian than in the mid Paleozoic.

 Phylogenetic relationships of the family Cyclopteridae were reconstructed based on osteological and external characters.  The monophyly of the family was strongly supported by 47 commonly recognized synapomorphies, including six autapomorphies (plus one additional autapomorphy, presence of a dorsal process on the pelvis, recognized after the phylogenetic analysis) among the suborder Cottoidei.  As a result of the cladistic analysis, a single most parsimonious phylogeny was obtained, based on characters in 32 transformation series.  A new classification of Cyclopteridae based on reconstructed relationships, including three subfamilies [Liparopsinae, Cyclopterinae and Eumicrotreminae (newly established)] and four genera (Aptocyclus, Cyclopsis, Cyclopterus and Eumicrotremus), is proposed.

The Family

A cladistic analysis of the Empidoidea and basal lineages of the Cyclorrhapha, based on morphological characters, confirms the monophyly of both groups as well as that of the                    Eremoneura. The resulting final trees are used to revise the classification of the Empidoidea to include the following five families: Empididae, Hybotidae, Atelestidae (including Nemedininae n. subfam.), Brachystomatidae rev. stat. (comprising the subfamilies Brachystomatinae, Ceratomerinae and Trichopezinae), and Dolichopodidae s.lat. The family Microphoridae is not recognized, and the Microphorinae and Parathalassiinae are assigned to the Dolichopodidae s.lat. The Dolichopodidae s.str. includes 15 subfamilies that were previously recognized within the family. Within the Empidoidea we found support for Atelestidae as the sister group to the Hybotidae and for the monophyly of Parathalassiinae + Dolichopodidae s.str. The Empididae remains poorly defined and the genera Homalocnemis Philippi, Iteaphila Zetterstedt, Anthepiscopus Becker, and Oreogeton Schiner are classified as incertae sedis within the                   Empidoidea. In addition, the following higher taxa are proposed: Symballophthalmini n. tribe, Bicellariini n. tribe, Oedaleinae rev. stat., and Trichininae rev. stat., which are all assigned to the Hybotidae. The genus Sematopoda Collin is tentatively assigned to Trichopezinae, and Xanthodromia Saigusa is transferred from Hemerodromiinae to Brachystomatinae.        All morphological characters are extensively discussed and illustrated, including details of the antennae, mouthparts, internal thoracic structures, wings, and male and female terminalia. In addition, a key to families and unplaced genus groups of the Empidoidea is provided. Feeding habits are also discussed in terms of the empidoid ground plan condition.

New Information

Phylogenetic relationships among the genera of the subfamily Oxycoryninae and other belids (Curculionoidea) were reconstructed by cladistic analysis using 21 terminals and 98 characters: 62 from imaginal morphology, 33 from larval morphology and three biological characters relating to host plants and larval feeding habits. Terminal taxa represent all extant genera of Oxycoryninae, two genera of each of the three tribes of Belinae plus two outgroup taxa used to root the tree. New information on the larvae and biology of the metrioxenines is used in phylogenetic reconstruction. In accord with the single optimal cladogram obtained, a revised classification of the Oxycoryninae is proposed. The subfamily is classified into three tribes (Oxycorynini, Metrioxenini and Aglycyderini), with the tribe Oxycorynini further classified into three subtribes (Oxycraspedina Marvaldi & Oberprieler, subtr. nov., Oxycorynina and Allocorynina) and the tribe Metrioxenini into two subtribes (Metrioxenina and Afrocorynina ( = Hispodini, syn. nov.)). Larval and adult unambiguous synapomorphies defining each clade are identified. Tracing the evolution of biological traits from the phylogenetic estimate indicates that drastic shifts to phylogenetically distant host plants occurred from the ancestral belid association with conifers. Structural, chemical and/or ecological similarities of the plant organs consumed apparently had a major influence in the colonisation of different plant taxa by this group of weevils.

Gall Induction

The molecular-based phylogenetic analysis of the subfamily Tephritinae, the subfamily that contains almost all the cecidogenous species of the family Tephritidae, has reassigned several tribes and groups of genera and modified their concepts based on morphology alone to other tribes and, thus, changed the hypothetical scenarios of evolution of fly/host–plant relations and, in particular, the gall induction in different phylogenetic lineages. Gall induction is shown to arise independently within the Myopitini (in two lineages), Cecidocharini, Tomoplagia group of genera, Eurostini, Eutreta, Tephritis group of genera, Platensinini, Campiglossa group of genera, and Sphenella group of genera independently and more or less synchronously due to the shift to host plants with smaller flower heads and sensitive to larval feeding causing tissue proliferation. This was possibly a result of temporary aridization of the grassy biomes in the Nearctic and Afrotropic regions in the late Miocene or early Pliocene.

Outgroup Species

Rhabdepyris (Epyrinae) is a cosmopolitan genus comprised of 132 species. No morphological synapomorphies are known for the genus and the genus is characterized by a combination of characters common to most Epyrini. Herein, we performed a cladistic analysis based on morphological characters to test the monophyly of Rhabdepyris. The three known subgenera of Rhabdepyris (Chlorepyris, Rhabdepyris s. str., and Trichotepyris) and other Epyrini (Anisepyris, Bakeriella, Calyozina, Epyris, Laelius, Trachepyris) were included in the ingroup. The cladistic analysis of 48 taxa (46 ingroup species and two outgroup species) and 81 structural characters yielded 72 cladograms under equal weights, and one under successive weighting. Rhabdepyris was found to be polyphyletic; the subgenus Trichotepyris was closely related to Anisepyris whereas Rhabdepyris str. s. was closely related to Laelius. The subgenus Chlorepyris is paraphyletic. Morphological characters are discussed in the light of the new phylogeny; novel characters are proposed and illustrated, and a new classification of Rhabdepyris and Epyrini is proposed. The following nomenclatural changes are proposed: Trichotepyris is synonymized under Anisepyris (syn. n.); Chlorepyris is recognized as a separated genus (stat. rev.); all 12 American species of the subgenus Rhabdepyris are transferred to Laelius; 22 species of Trichotepyris are transferred to Anisepyris; 58 species are transferred to Chlorepyris. A remaining total of 40 species are now recognized in Rhabdepyris. The holotype of Rhabdepyris, R. myrmecophilus Kieffer, the type species of Rhabdepyris, is redescribed.
