Abstract Several systematic revisions of the superfamily Palaemonoidea Rafinesque, 1815 (Natantia) have been published, with molecular studies complementing morphological examination. Yet, the true systematic positions of two families within the superfamily have remained uncertain, one of these being Anchistioididae Borradaile, 1915, the second being Desmocarididae Borradaile, 1915. We constructed a further phylogeny of Palaemonoidea based on two mitochondrial and five nuclear markers to resolve this issue. AnchistioidesPaulson, 1875 (the sole genus of Anchistioididae) is recovered nested within Palaemonidae Rafinesque, 1815, calling into question the validity of Anchistioididae as a distinct family. We also review the morphological characters that have been used to support family level status of Anchistioides including mouthparts adaptations, telson ornamentation, larval morphology, the presence of an appendix interna on the first pleopod in both sexes, and the mandible with a distally flared molar process. Although the latter two characters appear to be synapomorphic to the genus, we contend that these are ambiguous and not well founded to support the family-level status of the genus. As a consequence, and supported by the phylogenetic results, Anchistioididae is herein considered to be a synonym of Palaemonidae.

A New Species

The classification of the superfamily Psylloidea is revised to incorporate findings from recent molecular studies, and to integrate a reassessment of monophyla primarily based on molecular data with morphological evidence and previous classifications. We incorporate a reinterpretation of relevant morphology in the light of the molecular findings and discuss conflicts with respect to different data sources and sampling strategies. Seven families are recognised of which four (Calophyidae, Carsidaridae, Mastigimatidae and Triozidae) are strongly supported, and three (Aphalaridae, Liviidae and Psyllidae) weakly or moderately supported. Although the revised classification is mostly similar to those recognised by recent authors, there are some notable differences, such as Diaphorina and Katacephala which are transferred from Liviidae to Psyllidae. Five new subfamilies and one new genus are described, and one secondary homonym is replaced by a new species name. A new or revised status is proposed for one family, four subfamilies, four tribes, seven subtribes and five genera. One tribe and eight genera / subgenera are synonymised, and 32 new and six revised species combinations are proposed. All recognised genera of Psylloidea (extant and fossil) are assigned to family level taxa, except for one which is considered a nomen dubium.

Phylogenomic Study

Abstract— The generic classification of the Thelypteridaceae has been the subject of much controversy. Proposed taxonomic systems have varied from recognizing the approximately 1200 species in the family within the single genus Thelypteris, to systems favoring upwards of 30 genera. Insights on intrafamilial relationships, especially for neotropical taxa, have been gained from recent phylogenetic studies; however, in the most recent classification, 10 of 30 recognized genera are either non-monophyletic or untested. We sequenced 407 nuclear loci for 621 samples, representing all recognized genera and approximately half the known species diversity. These were analyzed using both maximum likelihood analysis of a concatenated matrix and multi-species coalescent methods. Our phylogenomic results, informed by recently published morphological evidence, provide the foundation for a generic classification which recircumscribed 14 genera and recognized seven new genera. The 37 monophyletic genera sampled demonstrate greater geographic coherence than previous taxonomic concepts suggested. Additionally, our results demonstrate that certain morphological characters, such as frond division, are evolutionarily labile and are thus inadequate for defining genera.

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.

The Family

The aim of this study was to summarize the available data on larval morphology of the first zoea of the family Hippolytidae and describe the first zoeal stage of H. obliquimanus from two geographically distinct populations, Brazilian and Caribbean in order to discuss interand intraspecific variability. Ovigerous females of Hippolyte obliquimanus were collected at Cahuita (Limón, Costa Rica) and at Ubatuba (São Paulo, Brazil). We compiled the published descriptions of all available hippolytid Zoea I (66 spp., 21%), and all zoeae share several characteristics. However, such morphological features cannot be used to distinguish the first zoeae of Hippolytidae from other caridean larvae. Historically, the presence of an exopodal seta at the maxillule and the absence of the anal spine/papilla have been considered as characteristic for the Zoea I of the genus Hippolyte. The results of our revision, however, did not support these conclusions: although H. obliquimanus showed an exopodal seta at the maxillule, four congeners did not bear such structure; moreover, H. obliquimanus as well as one other congener have an anal spine/papilla. All morphological characters observed in the first zoeal stage of H. obliquimanus are shared with others species of the family Hippolytidae. Intraspecific variability in Hippolyte obliquimanus was detected in one morphological aspect: the first zoea had four denticles on the ventral margin of the carapace in the Brazilian population, while specimens from the Costa Rican population had three.

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 aim of the Colophon larval study was to enable researchers to identify the species found in the field; to use larvae as an alternative for adults in molecular studies; to comment on possible phylogenetic information that may contribute to the sub-familial placement of the genus; and to obtain habitat preference data. To achieve this, larvae of four Colophon species were examined and their main diagnostic morphological characters identified. Larvae live in a fairly homogeneous micro-habitat of moist, humus-rich soil in protected places such as under rocky overhangs and amongst the roots and tussocks of Restionaceae. Colophon larvae show small inter-specific differences and larval characters contributed little equivocal information from which phylogenetic support for family placement could be deduced. Apparently, as with many scarabaeoid groups (Trogidae, Scarabaeidae), larval morphology may not have diversified much from the basal ground-plan and it remains for other (adult) phylogenetically significant morphological characters or DNA to provide more clarity on Colophon’s subfamilial placement.

A New Species

Didymosphaeriaceae is a ubiquitous fungal family that is reported to include saprobic, endophytic and pathogenic species associated with a wide variety of substrates. The family is characterized by 1-septate ascospores and trabeculate pseudoparaphyses, mainly anastomosing above the asci. In recent treatments Appendispora, Didymosphaeria, Roussoella, Phaeodothis and Verruculina were placed in the family. The aim of the present study is to delineate phylogenetic lineages within Didymosphaeriaceae and allied genera. A new species, Didymosphaeria rubi-ulmifolii, was isolated and identified based on morphological characters and phylogenetic analyses of partial 18S nrDNA and 28S nrDNA nucleotide sequence data. Didymosphaeria rubi-ulmifolii clustered with Montagnulaceae as a separate genus, while two putative strains (HKUCC 5834 and CMW 22186) of D. futilis from GenBank clustered with Cucurbitariaceae and Didymellaceae, respectively. The new species is characterized by immersed to slightly erumpent ascomata immersed under a clypeus, a peridium with compressed cells of textura intricata, long trabeculate pseudoparaphyses, anastomosing mostly above the asci and brown, 1-septate ascospores with granulate ornamentation. Phylogenetic analysis in combination with morphology and a review of literature show that Appendispora, Phaeodothis, Roussoella and Verruculina should be excluded from the family. Phaeodothis belongs in Montagnulaceae, Verruculina in Testudinaceae, while Appendispora and Roussoella belong in Roussoellaceae. The position of Didymosphaeriaceae as a distinct family, based on 1-septate ascospores and trabeculate pseudoparaphyses, mainly anastomosing above the asci is doubtful. Fresh collections of more Didymosphaeria strains are needed for epitypification and to obtain sequence data to establish if this family can be maintained.

Biochemical Profiles

Biochemical studies on 72 species of marine sponges from tropical Australia showed that 42 of 132 biochemical characters were useful in describing relationships between the families Microcionidae, Raspailiidae and Axinellidae, and other members of the orders Poecilosclerida and Axinellida. Chemotaxonomic characters were obtained from profiles of free amino acids (34 species), carotenoid pigments (41 species), general proteins (62 species) and antibiotic activity against three human pathogens (42 species of sponges). Biochemical data essentially supported the existing division within class Demospongiae, i.e. Ceractinomorpha and Tetractinomorpha, with the notable exception that the 'tetractinomorph' families Raspailiidae and two genera of Axinellidae were found to be more closely related to the Ceractinomorpha. Within-group comparisons demonstrated that Microcionidae (14 species) and Raspailiidae (15 species) were relatively homogeneous in their biochemical profiles, indicating that they should remain separated at the family level, supporting similar conclusions based on morphological data. Similar trends were also shown for the families Desmacellidae (2 species) and Desmoxyidae (3 species), contrary to recent taxonomic revisions by other authors who hypothesised that these families might be heterogenous. Conversely, Axinellidae (27 species) contained at least three disparate groups of genera: one (i.e. Phakellia, Reniochalina) showing strong affinities with ceractinomorphs, a second (i.e. Acanthella, Pseudaxinyssa) and possibly a third (i.e. Axinella, Teichaxinella) showing closer similarities to Desmoxyidae, Hemiasterellidae and outgroups from Hadromerida and 'Lithistida'. These results provided a measure of support for the removal of Raspailiidae to Poecilosclerida, and the division of Axinellidae into several families, as proposed independently in recent revisions based on morphological evidence.

Basal Position

Porcellionidae is one of the richest families of Oniscidea globally distributed but we still lack a comprehensive and robust phylogeny of the taxa that are assigned to it. Employing five genetic markers (two mitochondrial and three nuclear) we inferred phylogenetic relationships among the majority of Porcellionidae genera. Phylogenetic analyses conducted via Maximum Likelihood and Bayesian Inference resulted in similar tree topologies. The mtDNA genes cytochrome oxidase I (COI) and 16s rRNA (16s) were used for clade dating using previously published mutation rates. Our results provide evidence against the monophyly of both Porcellionidae and the largest genus of the family Porcellio. These results are compared to previous published work based on morphological evidence. The genera Leptotrichus and Brevurus are not grouped with the rest of Porcellionidae whereas Agnaridae are grouped with part of Porcellionidae. Armadillidium and Schizidium (Armadillidiidae) occupy a basal position on the phylogenetic tree. Even though the African genera Tura and Uramba (distributed in East Africa) are grouped together there is no general geographical pattern in other sub-clades. Additional taxonomic issues that arise in this work such as the assignment of the recently described genus Levantoniscus, arealso discussed. The status of Porcellionidae should be further revised and morphological characters traditionally used in Oniscidea taxonomy should be reconsidered in view of molecular evidence. The origin of the monophyletic clade within Porcellionidae as indicated in the present work is dated back to the Oligocene (~32 mya).

The family Saturniidae is distributed on all continents except polar areas, and includes about 1528 species in 162 genera, being the group with the largest diversity among Bombycoidea. Approximately 970 species are known from the New World. However, recent molecular studies indicate 1861 species in 162 genera and nine subfamilies. The family Arsenurinae consists of 63 species distributed exclusively in ten Neotropical genera, with phylogenetic relationships poorly understood. The goal of this study was to test the monophyly of the subfamily, tribes and genera using cladistic analysis of adult morphological characters. The subfamily, tribes and genera were all recovered as monophyletic groups with the following relationships among genera: (Almeidaia ((Loxolomia, Copiopteryx) ((Rhescyntis) ((Grammopelta, Arsenura) ((Caio) ((Dysdaemonia, Titaea) Paradaemonia)))))). Both tribes, Arsenurini and Almeidaiini, share several characters, but morphological study of Almeidaiini demonstrates that it also presents significant differences.
