The Family

Despite their great importance as pests of cultivated plants worldwide, members of the family Tetranychidae have never been subjected to a thorough cladistic analysis to reveal the history and relationships among related genera. Herein, we provide the first phylogenetic analysis and taxonomic review of species of the genera Aponychus, Paraponychus and Stylophoronychus using morphological characters. The results indicate a monophyletic clade uniting the aforementioned genera, although none of the three genera were recovered as monophyletic. We reinstate the tribe Aponychini as the taxon containing those three genera. Aponychus bambusae and A. aequilibris are herein considered junior synonyms of Stylophoronychus vannus and A. corpuzae, respectively.

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.

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov.

Phylogenetic relationships within the largest family of entodiniomorphid rumen ciliates, the Ophryoscolecidae, were inferred from comparisons of small-subunit ribosomal RNA gene sequences. These included three new sequences from Diplodinium dentatum (1638 base pairs (bp)), Eudiplodinium maggii (1637 bp), and Ophryoscolex purkynjei (1636 bp). Using morphological characters, Lubinsky constructed a cladogram of the Ophryoscolecidae, and on the basis of his analysis, he divided the family into three subfamilies (Entodiniinae, Diplodiniinae, Ophryoscolecinae) to reflect his "natural" groupings (G. Lubinsky. 1957. Can. J. Zool. 35: 141 – 159). Our cladistic analysis, based on the limited morphological and ultrastructural data available, indicates that there are no synapomorphies supporting the Diplodiniinae sensu Lubinsky. However, based upon the six 18S sequences for the Ophryoscolecidae, the rumen ciliates are monophyletic and fall into three distinct groups corresponding to Lubinsky's subfamilial division of the family. Our molecular analysis shows Entodinium to be the earliest branching rumen ciliate (subfamily Entodiniinae) and Eudiplodinium, not Diplodiium, branching first among the diplodiniines.

Simulium (Hearlea) Vargas, Mart nez Palacios, & D az N jera 1957 is comprised of 20 known species that are largely confined to the area between M xico and Guatemala. Herein, all currently recognized species within this subgenus are described, illustrated, keyed (except males), and subjected to phylogenetic analysis. Geographic distributions for each species are also updated. Simulium deleoni Vargas, 1945, is synonymized with S. capricorne De Le n, 1944. Simulium paracarolinae new species, from Guatemala, is described from the larva. A cladistic analysis of all Hearlea species and representatives from three outgroups was conducted using 39 morphological characters. Although different character weighting methods yielded different topologies, all trees agreed that Hearlea is monophyletic is comprised of two species groups, based mainly upon characters of the larva and pupa: the Simulium juarezi group S. ayrozai Vargas, S. burchi Dalmat, S. canadense Hearle, S. capricorne De Le n, S. chiriquiense Field, S. contrerense D az N jera & Vulcano, S. dalmati Vargas & D az N jera, S. delatorrei Dalmat, S. estevezi Vargas, S. ethelae Dalmat, S. juarezi Vargas & D az N jera, S. microbranchium Dalmat, and S. nigricorne Dalmat and the S. carolinae group Simulium (Hearlea) carolinae De Le n, S. gorirossiae Vargas & D az N jera, S. johnsoni Vargas & D az N jera, S. larvispinosum De Le n, S. menchacai Vargas & D az N jera, S. paracarolinae n. sp., and S. temascalense D az N jera & Vulcano.

Single Clade

A phylogenetic analysis of selected anomuran, thalassinidean, and other decapod crustacean taxa, based on spermatozoal ultrastructural characters and spermatophore morphological characters, was performed and the following relationships of the taxa are elucidated from the trees produced. The Anomura are not a monophyletic assemblage, with the lomoid Lomis being exclusive of the remainder of the anomuran taxa, and the thalassinid Thalassina included in the anomuran clade. The synapomorphy joining the majority of the conventional anomuran taxa (Lomis excluded) is the cytoplasmic origin of the microtubular arms. When the palinurid and thalassinoid representatives are separately designated as outgroups, the Astacidea and Brachyura jointly formed a sister group to the Anomura. The superfamilies Thalassinoidea, Paguroidea, and Galatheoidea are not monophyletic groups. In all analyses the anomuran families Coenobitidae and Porcellanidae each form a monophyletic group. The paguroid family Diogenidae is paraphyletic, with the genera Clibanarius and Cancellus separate from a single clade containing the remaining diogenid genera. The families Paguridae and Parapaguridae form a monophyletic clade with the exception of Porcellanopagurus. The two representatives of the family Chirostylidae (Eumunida and Uroptychus) fail to associate with the other species in the Galatheoidea. The taxa in the family Galatheidae are not a monophyletic assemblage. The only investigated hippoid Hippa is portrayed as the sister group to the remainder of the anomuran taxa (with the exception of Lomis).

The first quantitative phylogenetic analysis within the spider family Philodromidae (using 65 morphological characters from 40 ingroup taxa) does not corroborate Schick’s division into the tribes Thanatini (Apollophanes O. P.-Cambridge, 1898, Pelloctanes Schick, 1965, Thanatus C. L. Koch, 1837; Tibellus, Simon, 1875) and Philodromini (Ebo Keyserling, 1884, Philodromus Walckenaer, 1826; Rhysodromus Schick, 1965). Instead, Ebo is sister to all other genera in the family, and a fraction of Philodromus (the histrio species-group = Rhysodromus Schick) are contained with the Thanatini. The forgotten genus Artanes Thorell, 1870 constitutes a well-defined distal taxon in a clade that contains the majority of Philodromus species. Here Artanes is considered a subgenus of Philodromus, and includes the margaritatus and the poecilus species-groups. The western Palearctic species of the subgenus are revised. Twelve species are (re-)described, keyed and illustrated: Philodromus blanckei (Wunderlich, 1995) (first description of ♀); P. calidus Lucas, 1846; P. femurostriatus, sp. nov. from the eastern Mediterranean; P. fuscomarginatus (De Geer, 1778); P. johani, sp. nov. from Crete; P. laricium Simon, 1875, removed from synonymy with P. corticinus (C. L. Koch); P. maghrebi, sp. nov. from northern Africa (♀ only); P. margaritatus (Clerck, 1757); P. parietalis Simon, 1875; P. pentheri, sp. nov. from the Caspian region and Albania (♀ only); P. pinetorum, sp. nov. from the Mediterranean; and P. poecilus (Thorell, 1872).

This study provides new and additional data on morphology and a phylogenetic analysis of the recently described species Pelagia benovici Piraino, Aglieri, Scorrano & Boero, 2014 from the Northern Adriatic (Mediterranean Sea). Comprehensive morphological analyses of diagnostic characters, of which the most significant are marginal tentacles anatomy, basal pillars, gonad pattern, subgenital ostia and exumbrellar sensory pits, revealed significant differences from the currently known genera Sanderia, Chrysaora and Pelagia in the family Pelagiidae. A phylogenetic analysis of mitochondrial genes (COI, 16S rRNA, 12S rRNA) and nuclear ribosomal genes (28S rRNA, ITS1/ITS2 regions), together with cladistic analysis of morphological characters, positioned Pelagia benovici as a sister taxon with Sanderia malayensis, and both share a common ancestor with Chrysaora hysoscella. Pelagia benovici does not share a direct common ancestor with the genus Pelagia, and thus we propose it should not belong to this genus. Therefore, a new genus Mawia, gen. nov. (Semaeostomeae : Pelagiidae) is described, and Pelagia benovici is renamed as Mawia benovici, comb, nov.

A taxonomic revision and phylogenetic analysis of the spider genus Epicratinus Jocqué & Baert, 2005 is presented. The phylogenetic analysis is based on a data set including 16 Epicratinus species plus 9 outgroups representing by five related zodariid gen­era and one of them considered most basal as the root. These taxa were scored for 49 morphological characters. Parsimony was used as the op­timality criterion and a sensitivity analysis was performed using different character weighting concavities. Five unambiguous synapomorphies support the monophyly of Epicratinus. Some internal clades within the genus are well-supported and their relationships are discussed. Epicratinus includes 16 species, all with males and females. A species identification key and distribution maps are provided for all. New morphological data are also pre­sented for five previously described species. All 16 species occur only in the New World. The following species are transferred to Epicratinus: E. perfidus (Jocqué & Baert), comb. nov. from Tenedos; Epicratinus perfidus Jocqué & Baert comb. nov. and newly synonymized with E. santacruz Grismado & Izquierdo and this last species is treated as the junior synonym. Epicratinus petropolitanus (Mello-Leitão) has the male described for the first time. The following 11 species are newly described as new: E. zangief sp. nov.; E. pegasus sp. nov.; E. pikachu sp. nov.; E. stitch sp. nov.; E. ehonda sp. nov.; E. anakin sp. nov.; E. vader sp. nov.; E. omegarugal sp. nov.; E. zelda sp. nov.; E. dookan sp. nov. and E. mauru sp. nov., all from Brazil.

New Oriental taxa of the Lygistorrhinidae - Blagorrhina gen. n., with B. blagoderovi sp. n. and B. brevicornis sp. n.; Gracilorrhina gracilis gen. n., sp. n.; and Labellorrhina gen. n., with L. grimaldii sp. n. and L. quantula sp. n. are described, and two undescribed species, known only from females, are characterized. Based on this new material, the family is redefined. The phylogeneticrelationships among the taxa of Lygistorrhinidae were studied by parsimony analysis using 43 morphological characters from the adults of 25 ingroup and one outgroup species. The cladistic analysis produced 14 most parsimonious cladograms. The solution obtained suggests unambiguously the following phylogeny: Palaeognoriste Meunier and “Lygistorrhina” asiatica Senior-White are successively sister groups of the rest of the Lygistorrhinidae; there is a clade Labellorrhina + (Gracil- orrhina + (Blagorrhina + ((Seguyola Matile + (Loyugesa Grimaldi & Blagoderov + Matileola Papp))))) with a monophyletic Lygistorrhina Skuse – Probolaeus Williston lineage as sister group. The phylogeny among the latter group remains largely unresolved.

AbstractThe systematics and phylogenetic relationships of the family Leptodactylidae are controversial as is the intrafamilial phylogeny of the leptodactylids. Here we analyze the relationships of the leptodactylid subfamily Hylodinae. This subfamily has been considered to be monophyletic and composed of three genera, Hylodes, Crossodactylus and Megaelosia. In the present study 49 characters were used, based on different studies on Leptodactylidae phylogeny. Maximum parsimony methods with unweighted and successively weighted characters were used to estimate the phylogeny of the Hylodinae. Upon analysis, the data provided further evidence of the monophyletic status of the three genera, with Megaelosia being the basal genus and the other two genera being sister taxa. The analysis with successive weighting results in a more resolved topology of the species subgroups of the genus Hylodes and separates this genus from Crossodactylus and confirms that the hylodines are monophyletic.
