Generic Relationships

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.

New Interpretation

Adult external morphology of the extant raptorial Mantispoidea (Insecta: Neuroptera: Mantispidae and Rhachiberothidae) is compared emphasizing the morphology of the subfamily Symphrasinae as a key group to understand the phylogenetic relationships among the members of the superfamily. Plega dactylota Rehn, 1939 is thoroughly characterized in order to exemplify the morphology of the Symphrasinae. Additionally, following a review of the literature and examination of comparative material of Dilaridae, Berothidae, Rhachiberothidae and all Mantispidae subfamilies, a new interpretation of the components of the raptorial apparatus (i.e., head, prothorax, grasping forelegs, as well as integumentary specializations) is presented. Also, wing venation for these groups is reinterpreted, and new homology hypotheses for wing venation are proposed based on tracheation and comparative analyses. Given the high morphological divergence on the genital sclerites within the Mantispoidea, plus the confusing previous usage of neutral terminology and terms referring to appendages across taxonomic and morphological studies, we attempt to standardize, simplify, and situate terminology in an evolutionary context under the “gonocoxite concept” (multi-coxopod hypothesis). The remarkable morphological similarity of the genital sclerites of Symphrasinae and Rhachiberothidae (sensu U. Aspöck & Mansell 1994) with the Nallachinae (Dilaridae) was taken as a starting point to understand the morphology of other Mantispidae subfamilies. Based on these morphological comparisons, we provide a revised phylogenetic analysis of Mantispoidea. This new phylogenetic analysis supports a sister group relationship between the family Rhachiberothidae, comprising Rhachiberothinae and Symphrasinae, and the family Mantispidae, including the subfamily Mantispinae and its sister taxa Drepanicinae and Calomantispinae, which may represent a single subfamily. Based on these analyses, raptorial condition probably evolved a single time in these insects and subsequently became diversified in the two sister clades of the raptorial Mantispoidea.

This paper reports discovery of the genus <em>Disphaerona</em> Jordan, 1902 in two widely separated regions in China: in three isolated highlands in Yunnan (the Cang Shan Range, Mt. Jizu and Mt. Haba) and in the Dabie Mountains of Hubei, at the border with Anhui. Till present the genus was known from China only from four specimens of<em> D.</em> <em>chinensis</em> (including its holotype) described from Sichuan in 1995. Sixteen specimens from each of the three newly detected localities in Yunnan were DNA barcoded and the data were made publicly available at dx.doi.org/10.5883/DS-DISPHAE. Temporal phylogenetic analysis revealed a topology suggesting monophyly and recent (0.2–0.4 Ma) origin of the populations on both Mt. Jizu and Mt. Haba. The population on the Cang Shan Range harbours representatives of both clades forming the ingroup, mtDNA of which diverged some 7.9 Ma. The habitus of the holotype of the only nominative Chinese <em>Disphaerona</em> species, <em>D. chinensis,</em> is illustrated, together with habitus and male and female genitalia of specimens newly discovered in both Yunnan and Hubei. All specimens of <em>Disphaerona</em> from Yunnan are seemingly conspecific and are taxonomically assigned to D. chinensis. Two similar males and one sympatric but dissimilar, smaller female from the Dabie Mountains do not have associated DNA barcode data. It remains unknown whether the three Dabie Mountains specimens are conspecific or even congeneric; pending this uncertainty they are tentatively treated as <em>Disphaerona</em> without a Linnaean name. <em>Disphaerona</em> population in the Dabie Mountains, if indeed a member of this hypothesised clade, forms the easternmost record of the genus. Monophyly and sister group of <em>Disphaerona</em> are briefly discussed and both are shown as unknown and unverifiable. A brief overview of the state of phylogenetic knowledge of Anthribidae is given, which is practically non-existing and with neither the family, nor any of its tribes and the vast majority of genera tested as monophyletic.

Morphological And Molecular Data

Although the taxonomy of the ca 18 000 species of butterflies and skippers is well known, the family-level relationships are still debated. Here, we present, to our knowledge, the most comprehensive phylogenetic analysis of the superfamilies Papilionoidea, Hesperioidea and Hedyloidea to date based on morphological and molecular data. We reconstructed their phylogenetic relationships using parsimony and Bayesian approaches. We estimated times and rates of diversification along lineages in order to reconstruct their evolutionary history. Our results suggest that the butterflies, as traditionally understood, are paraphyletic, with Papilionidae being the sister-group to Hesperioidea, Hedyloidea and all other butterflies. Hence, the families in the current three superfamilies should be placed in a single superfamily Papilionoidea. In addition, we find that Hedylidae is sister to Hesperiidae, and this novel relationship is supported by two morphological characters. The families diverged in the Early Cretaceous but diversified after the Cretaceous–Palaeogene event. The diversification of butterflies is characterized by a slow speciation rate in the lineage leading to Baronia brevicornis , a period of stasis by the skippers after divergence and a burst of diversification in the lineages leading to Nymphalidae, Riodinidae and Lycaenidae.

A phylogenetic analysis of the Mycetophiliformia (= Sciaroidea) was performed to determine the relationships among its families and to place the following genera of uncertain position in the system: Heterotricha, Ohakunea, Colonomyia, Freemanomyia, Rhynchoheterotricha, Chiletricha, Afrotricha, Anisotricha, Kenyatricha, Nepaletricha, Sciarosoma, Sciaropota, Insulatricha, Cabamofa, Rogambara, and Starkomyia. Eratomyia n. gen. is described based on a new species from Ecuador. Colonomyia brasiliana sp.n. and Colonomyia freemani sp.n. are described respectively from southern Brazil and Chile. The male of Cabamofa mira Jaschhof is described for the first time. A total of 64 terminal taxa and 137 transformation series (with 202 characters) were included in the data matrix, with a number of new features from thoracic morphology. Willi Hennig’s 1973 system for the higher Bibionomorpha was adopted using the name Mycetophiliformia for the Sciaroidea. The Mycetophiliformia are monophyletic. The family Cecidomyiidae appears as the sister group of the remaining Mycetophiliformia, followed by the Sciaridae. In the preferred topology, the Rangomaramidae appear as the group sister of a clade consisting of (Ditomyiidae + Bolitophilidae + Diadocidiidae + Keroplatidae) and of (Lygistorrhinidae + Mycetophilidae). The topology within the Rangomaramidae is (Chiletrichinae subfam. n. (Heterotrichinae subfam. n. ((Rangomaraminae + Ohakuneinae subfam. n.))). The Chiletrichinae include the genera Kenyatricha, Rhynchoheterotricha, Insulatricha, Chiletricha, and Eratomyia n. gen. Heterotrichinae and Rangomaraminae are monotypic. The subfamily Ohakuneinae includes Ohakunea, Colonomyia, Cabamofa, and Rogambara. The positions of Freemanomyia, Loicia, Taxicnemis, Sciaropota, Starkomyia, Anisotricha, Nepaletricha, and Sciarosoma are considered. Afrotricha might belong to the Sciaridae. The similarities used by many authors to gather the Sciaridae and Mycetophilidae in a clade are shown to be a combination of plesiomorphies and homoplasies.

The relationships of Scytodoidea, including the families Drymusidae, Periegopidae, Scytodidae and Sicariidae, have been con-tentious for a long time. Here we present a reviewed phylogenetic analysis of scytodoid spiders, emphasizing Periegops, theonly genus in the family Periegopidae. In our analysis the Scytodoidea are united by the fusion of the third abdominal entapo-physes into a median lobe, the presence of female palpal femoral thorns and associated cheliceral stridulatory ridges, a mem-branous lobe on the cheliceral promargin, and the loss of minor ampullate gland spigots. A basal split within Scytodoideadefines two monophyletic groups: Sicariidae and a group formed by Scytodidae as the sister group of Periegopidae plus Dry-musidae, all united by having bipectinate prolateral claws on tarsi I–II, one major ampullate spigot accompanied by a nubbin,and the posterior median spinnerets with a mesal field of spicules. Periegops is the sister group of Drymusidae, united by the regain of promarginal cheliceral teeth and a triangular cheliceral lamina, which is continuous with the paturon margin.

Generic Relationships

This article contains the first detailed osteological study of several flatfish species belonging to the three currently recognized genera of tongue soles (Cynoglossidae). The resulting information was used to reassess, following the cladistics methodology, the monophyletic status of the family and to put forward a hypothesis of generic relationships. The polarity of the character states was determined by outgroup comparison using the Soleidae as the sister group of the Cynoglossidae and the Achiridae as the sister group of the soleid–cynoglossid lineage. An analysis of numerous characters corroborated the monophyletism of the Cynoglossidae. It was also found that the genus Symphurus (Symphurinae) is monophyletic and is the sister group of the monophyletic Cynoglossus–Parapaglusia (Cynoglossinae) lineage. Parapaglusia was shown to be monophyletic, but no evidence was found to corroborate a similar status for Cynoglossus. An examination of the osteology of more species belonging to the speciose genera Symphurus and Cynoglossus is needed to further test this hypothesis of relationships.

AbstractA preliminary cladistic-phylogenetic analysis of the four Holarctic genera of Adelidae recognized is presented. The monophyly of the superfamily Incurvarioidea is demonstrated on the basis of three possible synapomorphies, and that of the family Adelidae on the basis of three others. The subgenus Cauchas Zeller, 1839 is given generic status, as it is demonstrated to represent the sister-group of Nemophora Illiger & Hoffmannsegg, 1798 and Adela Latreille, 1796. Chalceopla Braun, 1921 is a new synonym of Cauchas Zeller, 1839. A key to the genera, based on males, is given.

AbstractTwenty-three characters or character systems of adults and larvae of Terebrantes are analyzed for evidence of monophyly and phyletic relationships of Chalcidoidea, Mymaridae, and Mymarommatidae. The taxa are considered to be a monophyletic group based on 3 hypothesized synapomorphies: mesotrochanteral depressor without fu2-tr2 or mesoscutal portion of t2-tr2; axillar phragma as site of origin for all or part of t,-tr2 muscle; and independent basal ring absent from male genitalia. The family Mymaridae is considered to be monophyletic based on at least 3 apomorphies: fore wing with hypochaeta; head with frontal, median, and supraorbital sulci; and toruli distinctly closer to inner margin of eye than to each other. Chalcidoidea, including Mymaridae, is considered to be a monophyletic taxon based on 3 apomorphies: prepectus externally visible, at least dorsally adjacent to lateral edge of mesoscutum; mesothoracic spiracle positioned at exposed lateral edge of mesoscutum; and multiporous plate sensilla of antenna with unique structure, as described in text. Mymarommatidae is considered to be the monophyletic sister group of Chalcidoidea based on several apomorphies, including 4 autapomorphies: head composed of frontal and occipital sclerites, which are connected by pleated membrane along hyperoccipital region; hind wing stalk-like, without membrane and terminated in bifurcation that clasps fore wing; fore wing with reticulate pattern formed by raised lineations of membrane; and axillar portion of t2-tr2 muscle absent. Phyletic relationship of Serphitidae with Mymarommatidae is deemed inconclusive because relevant internal character states of amber fossil serphitids cannot be determined. It is suggested that mymarommatids be accorded family status, but not be assigned to superfamily until phyletic relationships are more accurately determined in Terebrantes. A matrix summarizes character-state distribution of most characters analyzed for Terebrantes, and a cladogram illustrates hypotheses of character-state evolution and proposed relationships.

Swimming Leg

Uncovering the systematics of CopepodaHarpacticoida, the second-most abundant component of the meiobenthos after Nematoda, is of major importance for any further research dedicated especially to ecological and biogeographical approaches. Based on the evolution of the podogennontan first swimming leg, a new phylogenetic concept of the Ancorabolidae Sars and Cletodidae T. Scott sensu Por (Copepoda, Harpacticoida) is presented, using morphological characteristics. It confirms the polyphyletic status of the Ancorabolidae and its subfamily Ancorabolinae Sars and the paraphyletic status of the subfamily Laophontodinae Lang. Moreover, it clarifies the phylogenetic relationships of the so far assigned members of the family. An exhaustive phylogenetic analysis was undertaken using 150 morphological characters, resulting in the establishment of a now well-justified monophylum Ancorabolidae. In that context, the Ancorabolus-lineage sensu Conroy-Dalton and Huys is elevated to sub-family rank. Furthermore, the membership of Ancorabolina George in a rearranged monophylum Laophontodinae is confirmed. Conversely, the Ceratonotus-group sensu Conroy-Dalton is transferred from the hitherto Ancorabolinae to the Cletodidae. Within these, the Ceratonotus-group and its hypothesised sister-group Cletodes Brady are combined to form a monophyletic subfamily Cletodinae T. Scott, subfam. nov. Consequently, it was necessary to restructure the Ancorabolidae, Ancorabolinae and Laophontodinae and extend the Cletodidae to include the displacement and exclusion of certain taxa. Moreover, comparison of the Ancorabolidae, Cletodidae, Laophontoidea and other Podogennonta shows that the Ancorabolidae and Cletodidae form sister-groups in a monophylum Cletodoidea Bowman and Abele, which similarly has a sister-group-relationship with the Laophontoidea T. Scott. According to the present study, both taxa constitute a derived monophylum within the Podogennonta Lang.

A comprehensive molecular phylogenetic analysis of the family Thamnophilidae indicated that the genus Myrmotherula is not monophyletic. The clade composed of M. guttata and M. hauxwelli is only distantly related to other members of the genus and should be removed from Myrmotherula. The phenotypic distinctiveness of the clade argues against merging it with its sister group Thamnomanes and no generic name is available for the guttata-hauxwelli clade. Consequently, we describe the genus Isleria for these two species, and designate Myrmothera guttata as its type species.
