Seventy-two morpho-anatomical characters were examined in 221 genera belonging to the families Blattidae, Polyphagidae, Blattellidae, and Blaberidae. They were cladistically analyzed and polarized using two mantids and two termites. As no autapomorphies of the family Blattellidae were found, the constituent subfamilies were used as terminal taxa together with other families. Three trees were found (CI = 0.81 and RI = 0.88, without autapomorphies) that differed only by the position of Nyctiborinae relative to Blattellinae and Ectobiinae. The strict consensus tree was [Blattidae [Polyphagidae [Anaplectinae [[Pseudophyllodromiidae, Blaberidae] [Nyctiborinae, Blattellinae, Ectobiinae]]]]]. The main discrepancies with McKittrick's tree were the monophyly of Polyphagidae (instead of paraphyly) and that the Blaberidae is the sister-group of Pseudophyllodromiinae (instead of the sister-group of Blattellinae, Ectobiinae, and Nyctiborinae). These results made it necessary to elevate the Anaplectinae and Pseudophyllodromiinae to familial status, and to give a new sense to the family Blattellidae, which includes only the subfamilies Blattellinae, Ectobiinae, and Nyctiborinae. This phylogeny was used to test current evolutionary hypotheses concerning sociality and reproductive behaviour; many traits were assumed to be ancestral to all cockroaches (protozoan symbionts and familial life habits) or preadaptive (progressing from advanced oviparity in Blattellidae to ovoviviparity in Blaberidae) that must actually be considered homoplasic.

Anatomical Characters

The phylogenetic position of the subfamily Pyrgulinae within the superfamily Rissooidea has been discussed very controversially. Different data sets not only led to different evolutionary scenarios but also to different systematic classifications of the taxon. The present study uses detailed anatomical data for two pyrgulinid taxa, the type species of the subfamily, Pyrgula annulata (Linnaeus, 1767), and the type species of the little known genus Dianella, D. thiesseana (Kobelt, 1878), as well as DNA sequencing data of three gene fragments from representatives of eight rissooidean families to A) infer the phylogenetic position of Pyrgulinae with emphasis on its relationships within the family Hydrobiidae, B) to study the degree of concordance between anatomyand DNAbased phylogenies and C) to trace the evolution of anatomical characters along a multi-gene molecular phylogeny to find the anatomical characters that might be informative for future cladistic analyses. Both anatomical and molecular data sets indicate either a very close or even sister-group relationship of Pyrgulinae and Hydrobiinae. However, there are major conflicts between the two data sets on and above the family level. Notably, Hydrobiidae is not monophyletic in the anatomical analysis. The reconstruction of anatomical character evolution indicates that many of the characters on which the European hydrobioid taxonomy is primarily based upon are problematic. The inability to clearly separate some hydrobiids from other distinct families based on those characters might explain why until only a few years ago, "Hydrobiidae" was a collecting box for numerous rissooidean taxa (mostly species with shells small and lacking any characteristic features). The present study not only stresses the need for comprehensive molecular studies of rissooidean taxa, it also demonstrates that much of the problems surrounding anatomical analyses in rissooidean taxa are due to the lack of comprehensive data for many representatives. In order to aid future comparativeanatomical studies and a better understanding of character evolution in the species-rich family Hydrobiidae, detailed anatomical descriptions for P. annulata and D. thiesseana are provided.Key words: Pyrgulinae, Pyrgula, Dianella, Hydrobiidae, phylogeny, DNA, anatomy, Greece

AbstractDescription of larval instars of Deronectes depressicollis Rosenhauer 1856, D. lareynii (Fair-maire 1858), D. latus (Stephens 1829), D. aubei (Mulsant 1843), and Scarodytes halensis (Fabricius 1787) is presented including a detailed chaetotaxic and porotaxic analysis of the cephalic capsule, head appendages, legs, last abdominal scgment and urogomphi. A phylogenetic analysis of 14 genera of the tribe Hydroporini, based on 22 larval characteristics was conducted with Hennig86. Three of the branches of the strict consensus tree have a statistical support greater than 60% according to the Parsimony Jackknifer. One of the supported clades is Antiporus Sharp + Nebrioporus Régimbart + Neonectes J. Balfour-Browne + Oreodytes Seidlitz + Stictotarsus Zimmermann + Scarodytes Gozis, of which the sister-group is the genus Deronectes Sharp. Consequently larval characters, in contrast to adult characters support the inclusion of Antiporus, Neonectes and Oreodytes in the Deronectes-group of genera. All members of this clade are characterized by: (i) presence of an occipital suture in first instar, (ii) presence of a constriction at level of occipital suture, (iii) absence of maxillary cardo, and (iv) insertion of the primary seta MX I on the maxillary stipes. Scarodytes is postulated to share a monophyletic origin with Nebrioporus, Stictotarsus, and Antiporus based on (i) the presence of natatory setae on femora, tibiae, and tarsi and (ii) the shape of the urogomphomere I which is more than 3.10 times longer than urogomphomere 2.

Phylogenetic relationships within the “symmetrical” hermit crab family Pylochelidae were analyzed for 41 of the 45 species and subspecies currently considered valid. In the analyses, 78 morphological characters comprised the data matrix and the outgroup consisted of Thalassina anomala, a member of the Thalassinidae, and Munida quadrispina, a member of the Galatheidae. A poorly resolved strict consensus tree was obtained from a heuristic parsimony analysis of unweighted and unordered characters, which showed the family Pylochelidae and the subfamilies Pylochelinae and Pomatochelinae to be monophyletic taxa – the latter two groups had the highest Bremer support values. Additionally, while the subgenus Pylocheles (Pylocheles) was strongly supported, the subgenera Xylocheles, and Bathycheles were not. More fully resolved trees were obtained when using implied weighting, which recognized the monotypic subfamilies Parapylochelinae, Cancellochelinae and Mixtopagurinae. The subfamily Trizochelinae was found to have four distinct clades and several ambiguously placed taxa.

Abstract A new taxon of a broad-snouted goniopholidid, Siamosuchus phuphokensis, gen. et sp. nov., was discovered in the Sao Khua Formation (ante-Aptian), northeastern Thailand. The specimen is described on the basis of an incomplete skeleton showing the premaxillae, maxillae, nasals, left lacrimal, frontal, left jugal, right postorbital, caudal part of the cranial table, most of the right part of the postcranial skeleton, and several heavily sculptured osteoderms. S. phuphokensis is distinguished from the other broad-snouted goniopholidids on the basis of the following characters: penetration of the nasals in the narial border; presence of a robust and high median ridge on the interorbital surface; lateral margin of the frontal forming the medial edge of the orbit; supraoccipital exhibiting a wide pentagonal shape. A phylogenetic analysis using 101 characters for 29 mesoeucrocodylian taxa and 3 outgroup taxa supports the monophyly of the family Goniopholididae. In addition, the Thai specimen forms a clade with the European Goniopholis. Based on our strict consensus tree, the generic name Goniopholis should be restricted to the European forms only.

This article presents the phylogenetic conclusions of an osteological study of species belonging to the subfamilies (Soleinae and Achirinae) of the dextral flatfish family Soleidae (Pieuronectiformes; Soleoidei). A cladistic analysis of the data revealed that the subfamilies, but not the family, are monophyletic. The Soleinae were found to be more closely related to the other soleoid family, the Cynoglossidae, than to the Achirinae. If we accept the principle that only monophyletic groups are to be admitted into Linnean classification, it is suggested that the two subfamilies be raised to the family level. The anatomical data led to the proposal (with caution) that the sister group of the achirid–soleid–cynoglossid lineage is the pleuronectid subfamily Samarinae. Consequently, it is suggested that the suborder Soleoidei be eliminated by incorporating its three families into the Pleuronectoidei which becomes monophyletic. Also, it is proposed that the Pleuronectid subfamilies (Pleuronectinae, Poecilopsettinae, Paralichthodinae, Rhombosoleinae, Samarinae) be raised to the family level. However, since the monophyletic status of these taxa is dubious (except for the Samarinae) any hypothesis including them must await a proper cladistic analysis of their intra- and inter-relationships.

Transformation Series

The osteologic and myologic characteristics of the family Pentacerotidae are described in detail. The family Pentaceroti-dae is a monophyletic group supported by 11 synapomorphies found in all family members. Of their synapomorphies, two(the second infraorbital and endopterygoid articulate with lateral ethmoid conditions) are considerably rare in percoidsand strongly support the monophyly of the family. A comparison of 44 transformation series among all species revealedfour equally parsimonious trees, and a strict consensus tree was adopted. On the basis of the inferred phylogenetic rela-tionships of the Pentacerotidae, this family was cladistically classified into two subfamilies and seven genera: Histiopter-inae (Histiopterus, Evistias, Zanclistius, Pentaceropsis, Paristiopterus, and Parazanclistius) and Pentacerotinae(Pentaceros). The center of origin of pentacerotids was inferred to be the Southern Australian region. I propose that the two families, Ostracoberycidae and Chaetodontidae, are closely related with Pentacerotidae.

Abstract A comprehensive phylogeny of species relationships of the Auchenipteridae is reconstructed here with a large-scale taxon sampling based on combined morphological and molecular datasets. The hypothesized phylogeny includes most species of Auchenipteridae (97 of 124 valid species) and multiple members of siluriform families as an outgroup (32 species) to embrace the diversity of forms among related catfishes. As the first large-scale phylogeny of the Auchenipteridae, comparison between taxa included information from both morphology (264 characters) and mitochondrial and nuclear molecular markers (3490 nucleotides) from five genes: coI, 16S, rag2, myh6 and SH3PX3. Trees were generated under two different optimality criteria (Maximum Parsimony and Bayesian Inference). A new classification for the family is presented herein to bring the taxonomy more in line with the new phylogenetic hypothesis. The strict consensus tree corroborates the monophyly of superfamily Doradoidea, family Auchenipteridae and its two subfamilies, Centromochlinae and Auchenipterinae. The new classification scheme proposes nine tribes in Auchenipteridae, based on the monophyly of major groups in both subfamilies. Centromochlus, Glanidium and Tatia are each recovered as paraphyletic. To maintain a monophyletic classification, some species treated as Tatia and Centromochlus are assigned to genera not previously recognized as valid.

Insight Into

The 3′ region of the matK gene from 17 species, representing 13 tribes and six subfamilies of the Poaceae, is used to investigate the potential of the gene in addressing systematic questions in the family. The aligned sequences were analyzed by the Wagner parsimony methods using PAUP and PHYLIP and by the neighbor-joining method. Out of the 583 bp sequenced, 30% were variable and 14.9% were informative. The strict consensus tree, rooted by Joinvillea (Joinvilleaceae), showed well-resolved major clades that represent the grass subfamilies. The bambusoid Phyllostachys appeared as a basal clade in the family. Oryza diverged either before or after the Pooideae in the parsimony and neighbor-joining methods, respectively. The three members of the Pooideae grouped in a monophyletic lineage in both analyses. Arundo (Arundinoideae) was basal to the subfamilies Panicoideae and Chloridoideae. Analysis of the various types of DNA mutations underscores the potential of the matK gene in providing insight into grass systematic and evolution.

Hexactinellid Sponges

The phylogenetic relationships within the family Spongicolidae were examined based on a cladistic analysis of 38 adult morphological characters with reference to two outgroup species of the family Stenopodidae. The strict consensus tree identified Microprosthema as the most basal genus, followed by Paraspongicola, Spongicola and the remaining genera. The Spongicoloides represents the most derived genus among spongicolids. The genera Spongicola, Spongicoloides and Spongiocaris should be redefined, because they formed paraphyletic clades. The cladogram indicates that symbiosis with the hexactinellid sponges is coincident with the loss of gills, exopods on maxillipeds 2 and 3, and with the loss of spination on carapace, pereopods, abdomen, tail fan etc. These losses in the spongicolids are thought to be secondarily derived in relation to their sponge-associated habitat.

Evidence Analysis

Larvae of 60 genera representing the following families and subfamilies of Scarabaeoidea were studied and analysed phylogenetically: Lucanidae (Aesalinae, Nicaginae, Syndesinae, Lampriminae, Lucaninae), Passalidae (Passalinae, Aulacocyclinae), Trogidae, Pleocomidae, Geotrupidae (Taurocerastinae, Lethrinae, Geotrupinae), Bolboceratidae, Ceratocanthidae, Hybosoridae, Glaphyridae, Scarabaeidae (Aphodiinae, Scarabaeinae, Melolonthinae, Dynastinae, Cetoniinae). Seventy-eight larval morphological characters were employed in the analysis. Our data confirm that Dascillidae are not closely related to Scarabaeoidea. The monophyly of the superfamily is supported by 20 apomorphic character states, 18 of them unique. Monophyly of the following scarabaeoid clades is supported (with the number of larval synapomorphies followed by the bootstrap value in parentheses): Scarabaeoidea without Passalidae (6/67), Passalidae (9/100), Pleocomidae (11/93), Trogidae (8/93), Glaphyridae (10/96), Lucanidae (9/95), Ceratocanthidae + Hybosoridae (5/74), Scarabaeinae (9/98). The family Ceratocanthidae was found to be paraphyletic with respect to Hybosoridae. Monophyly of the family Scarabaeidae is not supported. The resolution of the basal parts of the strict consensus tree is higher when using Dascillidae + Eulichadidae v. Agyrtidae + Helophoridae as an outgroup, but the differences in topology become insignificant after bootstrapping. It is suggested that larval morphology alone is not an adequate tool to address basal relationships of Scarabaeoidea and a total evidence analysis should be performed.
