The mantis genus Tenodera is composed of several species distributed across Africa, Asia and Australasia, along with recent human introductions to North America. Species of the genus are morphologically similar and utilise equivalent habitats across their distribution. Relationships among these species and the morphological characters used to diagnose them have never been formally tested, leaving authors to disagree as to the species composition of Tenodera. With DNA sequence data from five molecular loci and morphological characters from male genitalia, we reconstructed the phylogeny of Tenodera using multiple optimality criteria. All included species were found to be monophyletic in analyses of the combined data. Tenodera sinensis and T. bokiana were both supported as distinct species recovered in separate clades, resolving confusion as to their placement and classification. Our analysis identified a previously undescribed species of Tenodera collected in India, recovered as sister to T. aridifolia and T. sinensis, and exhibiting distinct male genital morphology. In light of the phylogeny, we characterise for the first time, and investigate the evolution of, the male genitalia, which allowed us to discover several transitions in structural forms. We also consider the connection of these transitions to sexual cannibalism and how this behaviour may have led to rapid evolution of the male genitalia.

Molecular Identity

Anopheles (Nyssorhynchus) oswaldoi (Peryassú, 1922) comprises a species complex in South America. To fully characterize other taxa within the Oswaldoi Complex, it is essential to fix the identity of the nominotypical member. Given that the no type was designated in the original description, a lectotype is formally designated from the remaining syntypes in the Museu Nacional do Rio de Janeiro. These and other recently collected specimens from the type locality (Espírito Santo, Brazil) and the State of São Paulo, Brazil were used to redescribe the species using morphological characters of the adult female, male and male genitalia, and the fourth-instar larva and pupa. The larva, pupa, and male genitalia are illustrated. Diagnostic morphological characters of the adult female and male genitalia are provided to distinguish An. oswaldoi s.s. from the morphologically similar An. konderi, An. galvaoi, and An. ininii. DNA sequence data from the second nuclear internal transcribed spacer region (ITS2) are included to fix the molecular identity of An. oswaldoi s.s.

Abstract A new tribe of braconid wasps provisionally included in the Rhyssalinae, Laibaleini trib. nov., type genus Laibalea gen. nov. (type species Laibalea enigmatica sp. nov.), from Kenya and the Central African Republic, is described. A molecular dataset, with emphasis on basally derived taxa based on four gene fragments (28S D2–D3 expansion region, COI barcode, elongation factor 1-alpha and 16S ribosomal DNA), was analysed both alone and in combination with a morphological dataset. Molecular phylogenetic placement of the new species into an existing subfamily is complicated by the extreme sequence divergence of the three sequences obtained for Laibalea. In both the combined sequence analysis and the combined DNA plus morphological tree, Laibalea is recovered as a sister group to the Rhyssalinae plus all non-cyclostome lineage braconids excluding Mesostoinae, Maxfischeriinae and Aphidiinae. A consensus of morphological characters and molecular analyses suggests inclusion of Laibalea either in the otherwise principally Holarctic subfamily Rhyssalinae or perhap more basally, in the principally Gondwanan Mesostoinae s.l., although we cannot exclude the possibility that it might represent a separate basal lineage. We place Laibalea in its own tribe, provisionally included in Rhyssalinae. The DNA sequence data are presented for several genera for the first time. Avga, the type genus of Avgini, is shown not to belong to Mesostoinae s.l. or Hormiinae, but its exact relationships remain uncertain. The generic compositions of Rhyssalinae and Mesostoinae s.l. are revised. Anachyra, Apoavga, Neptihormius, Neoavga and Opiopterus are shown to belong to Mesostoinae s.s. A key to the tribes of Rhyssalinae is provided.

Two new rust species, Chrysomyxa diebuensis and C. zhuoniensis, on Picea asperata are recognized by morphological characters and DNA sequence data. A detailed description, illustrations, and discussion concerning morphologically similar and phylogenetically closely related species are provided for each species. From light and scanning electron microscopy observations C. diebuensis is characterized by the nailhead to peltate aeciospores, with separated stilt-like base. C. zhuoniensis differs from other known Chrysomyxa species in the annulate aeciospores with distinct longitudinal smooth cap at ends of spores, as well as with a broken, fissured edge. Analysis based on internal transcribed spacer region (ITS) partial gene sequences reveals that the two species cluster as a highly supported group in the phylogenetic trees. Correlations between the morphological and phylogenetic features are discussed. Illustrations and a detailed description are also provided for the aecia of C. succinea in China for the first time.

Molecular Characters

An integrative taxonomic analysis of Hierodula patellifera (Audinet-Serville) is presented based on morphological and molecular characters (COI, 28S rDNA). During repeated trips to the Korean peninsula, we collected unusual specimens from Wanju-gun. They were similar to H. patellifera, but can be distinguished by a larger body size, the number and shape of spines on foreleg, and the shape of male genitalia. To examine the phenotypes and delimit H. patellifera from fourteen sampled populations, we used forecoxal spines and male genitalia as key morphological characters, as well as molecular data including gene tree monophyly and genetic divergence data. The molecular analyses (p-distance, neighbor-joining, and parsimony analyses) did not separate the specimens as two distinct species. The diagnostic characters of H. patellifera are illustrated with habitus images.

ABSTRACT The genus Bakawan includes species of haminoeid snails associated with mangrove habitats and mud flats in the Indo-West Pacific. Here, we revise the diversity and systematics of the genus Bakawan based on our recent molecular phylogeny (Oskars & Malaquias, 2019) and detailed analysis of morphological characters. We examined a range of morphological characters (the shells, external morphology of the animal, jaw, radula, gizzard plate and male reproductive system) using light and scanning electron microscopy. We also carried out a species delimitation analysis (we used the automatic barcode gap discovery method) based on cytochrome c oxidase subunit I DNA sequence data. Four distinct species were recognized: Bakawan rotundata (A. Adams, 1850), which is the type species of the genus and ranges from the eastern Indian Ocean to the western Pacific; B. fusca (A. Adams, 1850), currently known only from the Philippines; and two species new to science, B. puti n. sp., known only from the Philippines, and B. hedleyi n. sp., restricted to tropical eastern Australia.

Abstract The phylogeny of the Oriental leafhopper genus Amritodus is reconstructed, for the first time, based on 47 discrete morphological characters and DNA sequence data from one nuclear and two mitochondrial genes. The phylogenetic results show that Amritodus is not monophyletic, and its concept is narrowed here to include four species: Amritodus atkinsoni, Amritodus brevis, Amritodus brevistylus and Amritodus saeedi. The phylogenetic results support establishment of a new genus, Paramritodus gen. nov., with three new species,Paramritodus triangulus sp. nov. (type species), Paramritodus introflexus sp. nov., Paramritodus spatiosus sp. nov. and three species previously included in Amritodus: Paramritodus pistacious comb. nov., Paramritodus flavocapitatus comb. nov. and Paramritodus podocarpus comb. nov. In addition, Amritodus flavoscutatus is transferred from Amritodus to Hyalinocerus as Hyalinocerus flavoscutatus comb. nov. Keys to species of Amritodus and Paramritodus are provided.

The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis of morphological characters and map these characters onto a recently published phylogenetic tree obtained from DNA sequence data. Results of these and previous analyses strongly support the monophyly of four clades of Nothofagaceae that are currently treated as subgenera of Nothofagus. The four clades of Nothofagaceae are robust and well-supported, with deep stem divergences, have evolutionary equivalence with other genera of Fagales, and can be circumscribed with morphological characters. We argue that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Nothofagus with four subgenera.        Nothofagus is recircumscribed to include five species from southern South America, Lophozonia and Trisyngyne are reinstated, and the new genus Fuscospora is described. Fuscospora and Lophozonia, with six and seven species respectively, occur in New Zealand, southern South America and Australia. Trisyngyne comprises 25 species from New Caledonia, Papua New Guinea and Indonesia. New combinations are provided where necessary in each of these genera.

Phylogenetic Placement

AbstractThe phylogenetic placement of the genus Maronina was studied, based chiefly on phenotypic characters such as thallus colour and anatomy, secondary chemistry, the anatomy of the excipulum and the ascus-type. DNA sequence data of mitochondrial and nuclear ribosomal loci from some of the species support the hypothesis that Maronina is nested within Protoparmelia. Hence, Maronina is reduced to synonymy with Protoparmelia. Comparison of genetic distances suggests that the two varieties within M. orientalis should be regarded as distinct species. Consequently, the new combinations Protoparmelia australiensis (Hafellner & R. W. Rogers) Kantvilas et al., P. corallifera (Kantvilas & Papong) Kantvilas et al., P. hesperia (Kantvilas & Elix) Kantvilas et al., P. multifera (Nyl.) Kantvilas et al., and P. orientalis (Kantvilas & Papong) Kantvilas et al. are proposed.

AbstractFor the first time, DNA sequence data were obtained for three species of Trichostrongylus from Russia. Internal transcribed spacer (ITS-2) of ribosomal DNA was sequenced for T. axei, T. colubriformis and T. probolurus from sheep from the Moscow region. ITS-2 rDNA length was estimated as 238 nucleotides for T. colubriformis and T. probolurus and 237 nucleotides for T. axei. The G+C content of the ITS-2 sequences of T. colubriformis, T. axei and T. probolurus were 31 %, 32 % and 34 % respectively. The level of interspecific differences in ITS-2 of rDNA of T. axei, T. probolurus and T. colubriformis ranged from 3 to 4 %. The ITS-2 sequences from the Russian specimens were compared with those of T. axei, T. probolurus and T. colubriformis from Australia and Germany. Intraspecific variation ranged from 0 % in T. colubriformis to 3.0 % in T. axei.

Life stages of Henosepilachna implicata (Mulsant), an economically important species of Epilachnini in India, are documented and illustrated. Mitochondrial DNA sequence data is provided for the first time for H. implicata with additional details on its host plants, distribution, and natural enemies. Its similarities and differences with other common pestiferous Henosepilachna spp. in India such as H. vigintioctopunctata (F.), H. septima (Dieke) and H. pusillanima (Mulsant) are discussed. Epilachna circularis Korschefsky, 1933 is found to be conspecific with H. implicata and is reduced to a junior synonym of the latter (new synonym). Notes are given on the distribution and natural enemies of some other species of Epilachnini of the Indian region.
