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.

AbstractThis paper is chiefly aimed at reassessing the limits of four bombycoid families, namely the Eupterotidae, Saturniidae, Lemoniidae, and Brahmaeidae. An incompletely resolved cladogram is proposed for the whole 'bombycoid complex' (Mimallonoidea + Lasiocampoidea + Bombycoidea). Within the Bombycoidea, the primary dichotomy is considered to lie between the Eupterotidae + Bombycidae s.lat. + Endromidae + Mirinidae + Saturniidae, and the Carthaeidae + Lemoniidae + Brahmaeidae + Sphingidae. Sharing at least nine synapomorphies, the Lemoniidae and Brahmaeidae are regarded as reliable sister groups, and the Lemoniidae + Brahmaeidae are proposed as a sister group to the Sphingidae. Another newly proposed clade groups together the Endromidae, Mirinidae and Saturniidae. At family level, the Hibrildidae are synonymized with the Eupterotidae (syn. n.), for which the most significant autapomorphy lies in a previously unnoticed particularity of the female hind leg (distitarsus typically provided with a midventral row of spines). Sexual dimorphism in leg structure also leads to a redefinition of the Saturniidae, a family which must include, with subfamily rank (stat. rev.), the 'Oxytenidae' and 'Cercophanidae' of modern authors. A pair of distal, tooth-like structures on the fourth tarsomere of the female fore leg can thus be ascribed to the ground plan of the Saturniidae, along with a few other convincing autapomorphies. On the other hand, the 'Apatelodidae' are only tentatively placed in the 'Bombycidae sensu lato', a group provisionally resurrected insofar as the Apatelodidae sensu auct. prove to be diphyletic. As a matter of fact, the 'apatelodid' subfamily Epiinae is synonymized with the Bombycinae (syn. n.) in consideration of a rather large number of synapomorphies. When more extensively studied, the morphology of the eighth sternum of the male abdomen might lead to a slightly different, more restricted, concept of the Bombycidae (Le. excluding 'true' Apatelodidae). Often regarded as incertae sedis, the African genera Sabalia Walker and Spiramiopsis Hampson are definitely assigned to the Lemoniidae and Brahmaeidae respectively. Autapomorphies of these two families are recorded and discussed, as are those found to characterize the Sphingidae. Three subfamilies are tentatively recognized within the latter (Smerinthinae stat. rev., Sphinginae, Macroglossinae), five within the Eupterotidae (Hibrildinae, Tissanginae, Janinae, Panacelinae, Eupterotinae), and four within the Bombycidae s.lat. (Apatelodinae, Phiditiinae subfam. n., Prismostictinae [= Oberthueriinae, syn. rev.], Bombycinae). Three of these subfamilies are considered in a new sense, viz. the Panacelinae, Apatelodinae, and Bombycinae. Although the phylogeny of the Saturniidae is not fully taken into account in the present study, the composition of three saturniid subfamilies is critically examined (Oxyteninae, Cercophaninae, Ludiinae), and the Oxyteninae are viewed as the most 'primitive' member of the family.

Cladistic Analyses

The taxonomy ofHomopholis C.E.Hubb. is revised, and anew genus Whalleya K.E.Wills & J.J.Bruhl isdescribed. Relationships among the known species ofHomopholis (H. belsonii C.E.Hubb.,H. proluta F.Muell., and a putative species,H. sp. nov.), and the relationships betweenHomopholis and other genera within the Paniceae were investigated. Morphological and anatomical data forHomopholis and selected species ofDigitaria and Panicum were analysed phenetically and cladistically. The value and contribution ofcharacters to the findings were assessed. In the phenetic analyses, threedistinct clusters of species were formed. The first cluster includedDigitaria coenicola (F.Muell.) Hughes,D. divaricatissima (R.Br.) Hughes andD. papposa (R.Br.) P.Beauv.; the second,Panicum effusum R.Br.,P. queenslandicum Domin var.queenslandicum and P. simileDomin; and the third, H. sp. nov.,H. proluta, H. belsonii andP. subxerophilum Domin. Specimens ofH. belsonii noticeably separated from the other threespecies. For the cladistic analyses, species ofEntolasia and Thyridolepis were used as outgroup taxa. One most parsimonious tree was produced.Homopholis belsonii was well supported as the most basalmember of the ingroup. The three species ofDigitariaformed a well-supported clade.Panicum effusum, P. queenslandicumvar. queenslandicum and P. simileformed a well-supported clade, and were the sister group toEntolasia marginata (R.Br.) Hughes andE. stricta (R.Br.) Hughes.Panicum subxerophilum was in a clade (=Whalleya) with H. sp. nov. andH. proluta, with P. subxerophilumand H. proluta as sister species.

The Subject

The family Alestidae (also referred to as the African Characidae) comprises the African dwarf forms ("Petersiini") and the genera Alestes, Brycinus, Bryconaethiops, and Hydrocynus. Although several authors have presented characters to support the monophyly of the family, a cladistic analysis of the group has not been published. Furthermore, the interrelationships of the constituent groups are the subject of some controversy. A cladistic analysis of the Alestidae is presented, including characters to support the monophyly of the family. The results of this study indicate that several species should be removed from the genus Brycinus, that Hydrocynus is the sister group of Alestes s.str. (containing only five species), and that the dwarf alestids ("Petersiini") do not form a monophyletic group.

Examination of museum specimens belonging to the cyphophthalmid Gondwanan family Pettalidae has rendered a collection of specimens placed in the new genus Karripurcellia. The genus includes three species, K.�peckorum, sp. nov., K. sierwaldae, sp. nov. and K. harveyi, sp. nov., from the Pemberton area in Western Australia. These are the first cyphophthalmid species found outside Queensland in Australia. Karripurcellia, gen. nov. is distinguished from other Australian pettalids by the lack of modifications in the anal plate, as well as the lack of the typical male anal glands of pettalids, sironids and the stylocellid genus Fangensis Rambla, 1994. Two of the species, K. peckorum, sp. nov. and K. sierwaldae, sp. nov., live sympatrically and have been collected in the same litter samples in one locality. The proposition of the new genus is accompanied by a cladistic analysis of all pettalid genera and most species within each genus, with the exception of the species-rich genus Rakaia Hirst, 1925. The cladistic analysis supports the monophyly of the Karripurcellia, gen. nov. species, but their sister-group relationships are unclear. However, the remaining Australian species cluster with the pettalids from New Zealand and South Africa, but not with Karripurcellia, sp. nov.

A reappraisal of the eggshell of ratites clarifies aspects of its microstructure and ultrastructure. The phylogenetic usefulness of the eggshell data, consisting of discrete characters, is assessed using eggshell characters alone and by adding the eggshell characters to a data matrix from the literature based on skeletal characters. The resultant tree from the eggshell data alone yields Apteryx as the most basal ratite, dinornithids as the sister taxon of a clade of large living ratites, with Casuarius and Dromaius in a sister-group relationship. The combined eggshell and skeletal analysis revealed most groupings within Ratitae that were based on previous cladistic analysis of the skeletal characters alone, but also supports two equally parsimonious topologies: one identifies Dinornithidae and Apteryx as a clade at the base of Ratitae, and the other identifies Apteryx as the sister taxon of a clade consisting of all the other ratites. It is determined that the characteristics used to define the improperly named "ratite morphotype" in the current eggshell parataxonomy are not synapomorphies of the eggshell of Ratitae. An expanded cladistic analysis of the eggshells of avian and non-avian theropods is required to determine the phylogenetic usefulness of the characteristics of the ratite morphotype.

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.

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.

Enzyme polymorphism and 18S rRNA sequences have been used to measure genetic distances between several species of Platyhelminthes belonging to different taxa including freshwater and parasitic forms. We have used these data to address unresolved phylogenetic and taxonomic problems with this group at several different levels ranging from phylum to subgenus. The main conclusions supported by the data seem to be the following: (i) 18S rRNA data strongly suggest that the Platyhelminthes are monophyletic, being a sister-group to the other Eubilateria; a similar conclusion applies to the Paludicola as to the rest of Platyhelminthes studied; (ii) 18S rRNA and enzyme data indicate that the family Dugesiidae of the Paludicola is monophyletic with respect to the other two families, Planariidae and Dendrocoelidae; and (iii) the subgenus Schmidtea of the genus Dugesia is monophyletic with respect to the other two subgenera of Dugesia, Dugesia and Girardia. Other aspects of the relationships of subgenera and families could not be satisfactorily resolved, but point to new problems that should be addressed in future studies, namely the taxonomic status of the family Planariidae and the relationships between the genera and subgenera of the family Dugesiidae.

A new wood wasp, Cratosirex sennlaubi gen. et sp. nov., is described and figured from one specimen collected from the Lower Cretaceous Crato Formation in northeastern Brazil. This new genus is placed in the new siricid subfamily Cratosiricinae subfam. nov., based on a combination of plesiomorphic and autapomorphic characters. The presence of small and sub-equal forewing cells 1R1 and 2R1 is a synapomorphy with the extant subfamily Siricinae, absent in the other extinct subfamilies †Auliscinae and †Gigasiricinae, supporting a sister group relationships with the Siricinae. Our new discovery expands the distribution range of Siricidae fossil records, highlights the antiquity of the family, and emphasizes the need for more studies of this particular insect lineage in the Mesozoic deposits. Currently, all the representatives of the crown group of the extant Siricidae are Cenozoic.

A phylogenetic hypothesis for the patellid limpets is reconstructed by cladistic analysis of morphological characters from 37 species, representing all but one of the living members of the family. Characters included in the analysis are derived from shell shape and microstructure, headfoot and pallial complex, radula and sperm. The species fall into four clades, providing the basis for a new phylogenetic classification into four monophyletic genera: Helcion (four species; southern Africa), Cymbula (eight species; southern Africa, eastern Atlantic, southern Indian Ocean), Scutellastra (17 species; southern and southwestern Africa, Australia, Indo–West Pacific, Eastern Pacific) and Patella (nine species; northeastern Atlantic and Mediterranean). The analysis suggests sister–group relationships between Helcion and Cymbula , and between Scutellastra and Patella . In combination with present–day patterns of geographical distribution, this phylogenetic hypothesis is used to discuss the historical biogeography of the Patellidae. Scutellastra may have originated in southern Africa and dispersed across the Pacific, or alternatively may be a primitively Tethyan group. Both Helcion and Cymbula appear to have originated in southern Africa, but three Cymbula species have dispersed respectively to northwest Africa, St Helena and the southern Indian Ocean. The patellids of the northeastern Atlantic form a single clade, Patella (including P. pellucida ), which may have arrived by northward dispersal of an ancestor from southern Africa, or possibly by vicariance of a widespread ancestral Tethyan distribution. The known fossil record of patellids is too fragmentary to permit choice between these alternatives.
