 Recent molecular phylogenies of the Lepidoziaceae indicate that the current classification is incongruent with the phylogeny. Although substantial uncertainties remain, an interim classification is needed. The classification proposed includes a broader definition of the Lembidioideae, reinstatement of Neolepidozia and Tricholepidozia and the recognition of the new genus Ceramanus. While the Zoopsidoideae are unlikely to represent a monophyletic group, it is not yet possible to provide a phylogenetically accurate revision of this subfamily.

Current Classification

The current classification ofPristoceradoes not have taxonomic or cladistic support, which results in mistakes during the allocation of its species, especially within the generaDicrogenium,Kathepyris,NeodicrogeniumandDiepyris. This study aimed to verify the monophyly and to present a cladistic hypothesis for the genus. The analyses were based on 147 characters of 50 terminal taxa. Parsimony analyses under both equal and implied weightings were performed. All cladograms obtained by the implied weighting recoveredPristoceraand all four related genera as polyphyletic. A monophyletic group withPristoceraand the other genera of the inner group was formed. This group was supported by 13 synapomorphies, with one of them exclusive, as follows: the presence of a hypopygium that was divided into two parts. Based on our results, the following new genus-group synonyms were established:Dicrogenium,Kathepyris,NeodicrogeniumandDiepyrissyn.n. forPristocera, and their 39 species were combined with the latter. The following new names are proposed to avoid homonyms:Pristocera zatanom.n. forDicrogenium bequaertiBenoit,Pristocera zelanom.n. forKathepyris katangensisBenoit,Pristocera zinticanom.n. forKathepyris uelensisBenoit,Pristocera zontanom.n. forNeodicrogenium bequaertiBenoit andPristocera zuncranom.n. forNeodicrogenium tuberculatum(Turner). Therefore,Pristoceranow comprises 124 species from the Old World.

Molecular Phylogenies

Recently published molecular phylogenies of the Annonaceae have confirmed the long-held hypothesis that the large paleotropical genus Polyalthia is polyphyletic. Species previously assigned to Polyalthia are now known to belong to up to six distinct, generally well-supported clades. Three members of a group of six species previously referred to as the Polyalthia hypoleuca complex form a monophyletic group (with 99% bootstrap support) that is only distantly related to the other species of Polyalthia sampled. Putative morphological synapomorphies are assessed, and justification provided for validating a new generic name, Maasia. Six species names in the Polyalthia hypoleuca complex are accordingly transferred to Maasia: M. discolor, M. glauca, M. hypoleuca, M. multinervis, M. ovalifolia, and M. sumatrana.

A new scarab beetle genus and species, Puelchesia gracilis, is described based on specimens collected in the Monte biogeographic province of west central Argentina. This genus is placed in the tribe Pachydemini based on an evaluation of the characters within the context of the current classification of the subfamily Melolonthinae. The distribution and natural history of the taxon is also discussed.

The Family

The single and endemic species of Eupterote Hübner recorded from Australia is shown not to possess the male genitalia typical of this genus, nor of any other genus of Eupterotidae, and it is consequently placed in a new genus, Ebbepterote Oberprieler, Nässig & Edwards, as E. expansa (T. P. Lucas, 1891), comb. nov. Its genitalia are compared with those of many Asian and African genera of Eupterotidae, resulting in a revised classification and redefinition of the major eupterotid lineages. Five groups are defined: a probably paraphyletic 'basal' Ganisa-group and likely monophyletic subfamilies Janinae (including Tissanga Aurivillius and Hibrildes Druce), Striphnopteryginae, Eupterotinae and Panacelinae. Ebbepterote and the New Guinean 'Eupterote' styx Bethune-Baker species-complex are included in Striphnopteryginae, which is otherwise restricted to Africa. Cotana Walker is reassigned to Eupterotinae from Panacelinae and Sphingognatha Felder is resurrected from synonymy with Eupterote. The genitalia of Ebbepterote and several other critical genera are illustrated, demonstrating that the shape of the uncus does not constitute a suitable synapomorphy for defining the Eupterotidae as a monophyletic group. Another alleged eupterotid synapomorphy, the presence of a row of midventral spurs on the apical tarsal segment of the hindleg of the female, is shown to occur only sporadically in the family but also outside of it, in the lemoniid–brahmaeid–sphingid clade of Bombycoidea. As a result, the monophyly of the Eupterotidae currently rests only on a single, cryptic character of the mesoscutum of the imago and is in urgent need of substantiation.

This paper records a new genus Taungurungia, which is the first new taxon with emergences to be described from the Lower Devonian of Victoria. The fossil is preserved primarily as a compression and impression, and lacks internal anatomy. The fossil extends our knowledge of known variations within early land plants, with most characteristics, such as emergences and H- or K-branching, redolent of affinities with the zosterophylls. However, having a large ovate terminal sporangium, the fossil adds to taxa that in some cases have been provisonally allied to the zosterophylls with elongate sporangia; this further demonstrates the need for reassessment of the Zosterophyllopsida.

Cladistic Classification

The new genus Ambophthalmos is recognised for "Neophrynichthys" angustus and "Neophrynichthys" magnicirrus, two southern Pacific psychrolutids. A hypothesis of psychrolutid phylogenetic relationships based on parsimony analysis of osteological characters is presented. Two synapomorphic characters suggest that A. angustus and A. magnicirrus form a monophyletic group: the supratemporal is posteriorly fused to the posttemporal and arch 2 is medially fused to its antimere. Four characters suggest that Cottunculus is monophyletic and five synapomorphic characters suggest that Ambophthalmos is sister to Cottunculus. A cladistic classification of the Psychrolutidae includes five subfamilies sequenced as Dasycottinae, new; Eurymeninae, new; Cottunculinae, redefined; Malacocottinae, new; and Psychrolutinae, unchanged.

AbstractThe lichenicolous ‘heterobasidiomycetes’ belong in the Tremellomycetes (Agaricomycotina) and in the Pucciniomycotina. In this paper, we provide an introduction and review of these lichenicolous taxa, focusing on recent studies and novelties of their classification, phylogeny and evolution. Lichen-inhabiting fungi in the Pucciniomycotina are represented by only a small number of species included in the genera Chionosphaera, Cyphobasidium and Lichenozyma. The phylogenetic position of the lichenicolous representatives of Chionosphaera has, however, never been investigated by molecular methods. Phylogenetic analyses using the nuclear SSU, ITS, and LSU ribosomal DNA markers reveal that the lichenicolous members of Chionosphaera form a monophyletic group in the Pucciniomycotina, distinct from Chionosphaera and outside the Chionosphaeraceae. The new genus Crittendenia is described to accommodate these lichen-inhabiting species. Crittendenia is characterized by minute synnemata-like basidiomata, the presence of clamp connections and aseptate tubular basidia from which 4–7 spores discharge passively, often in groups. Crittendenia, Cyphobasidium and Lichenozyma are the only lichenicolous lineages known so far in the Pucciniomycotina, whereas Chionosphaera does not include any lichenicolous taxa.

Galeaspids are an endemic clade of jawless stem-gnathostomes known as ostracoderms. Their existence illuminates how specific characteristics developed in jawed vertebrates. Sinogaleaspids are of particular interest among the galeaspids but their monophyly is controversial because little is known about Sinogaleaspis xikengensis. Newly discovered sinogaleaspids from the Lower Silurian of Jiangxi, China provide a wealth of data and diagnostic features used to establish the new genus, Rumporostralis gen. nov., for Sinogaleaspis xikengensis. A morphological study showed that the sensory canal system of sinogaleaspids had mosaic features similar to those of three known galeaspids. There are 3–8 pairs of transverse canals in the Sinogaleaspidae, which suggests that the sensory canal system of galeaspid probably had a grid distribution with transverse canals arranged throughout the cephalic division. Phylogenetic analysis of Galeaspida supports the monophyly of the Sinogaleaspidae, consisting of Sinogaleaspis, Rumporostralis, and Anjiaspis. However, Shuyu and Meishanaspis form another monophyletic group, Shuyuidae fam. nov., which is outside all other eugaleaspidiforms. We propose a cladistically-based classification of Galeaspida based on our analysis.
