Based on the first molecular phylogenetic analyses of samples from northeast India, specimens referred to Rhabdops from this region are more closely related to the southeast and east Asian natricine genera Opisthotropis Günther, 1872 and Sinonatrix Rossman & Eberle, 1977 (as well as to New World and western Palearctic natricines) than to peninsular Indian (true) Rhabdops. Morphologically, these northeast Indian populations differ from other natricines by having a single (‘fused’ or unpaired) internasal shield and a single prefrontal shield. Given the morphological and phylogenetic distinctiveness of these northeast Indian populations, we refer them to a new genus, Smithophis gen. nov., and transfer Rhabdops bicolor (Blyth, 1854) to Smithophis bicolor comb. nov. Based on morphological and molecular variation within our northeast Indian sample, we additionally describe Smithophis atemporalis sp. nov. from the state of Mizoram.

Large Distribution

The superfamily Bogidielloidea is one of the most wide-ranging hypogean amphipod taxa currently known, comprising over 130 species in 43 genera occurring on every continent except Antarctica. This large distribution among such cryptic organisms is curious, especially when combined with weak morphological characters uniting the superfamily. A unique new genus and species of bogidielloid amphipod, Simplexia longicrus, gen. et sp. nov., described from Terrell County, Texas, sheds light on the evolutionary relationships within this grouping. Molecular phylogenetic analyses of the order Amphipoda using two nuclear genes and one mitochondrial gene reveal that this species and the sympatric Parabogidiella americana form a clade removed from other sequenced members of Bogidiellidae sensu stricto, and, as such, the two species are placed in the newly erected Parabogidiellidae, fam. nov. Additional phylogenetic analyses of the cosmopolitan Bogidiellidae are recommended to further resolve its systematics.

Partitioning Pattern

AbstractThe Enenteridae Yamaguti, 1958 and Gyliauchenidae Fukui, 1929 exhibit an interesting pattern of host partitioning in herbivorous fishes of the Indo-West Pacific. Enenterids are known almost exclusively from fishes of the family Kyphosidae, a group of herbivorous marine fishes common on tropical and temperate reefs. In contrast, gyliauchenids are found in most of the remaining lineages of marine herbivorous fishes, but until the present study, had never been known from kyphosids. Here we report on the first species of gyliauchenid known from a kyphosid. Endochortophagus protoporus gen. nov., sp. nov. was recovered from the Western buffalo bream, Kyphosus cornelii (Whitley, 1944), collected off Western Australia. Kyphosus cornelii also hosts an enenterid, Koseiria allanwilliamsi Bray & Cribb, 2002, and is thus the first fish known in which enenterids and gyliauchenids co-occur. Molecular phylogenetic analyses place the new species close to those of Affecauda Hall & Chambers, 1999 and Flagellotrema Ozaki, 1936, but there is sufficient morphological evidence, combined with the unusual host, to consider it distinct from these genera. We discuss factors which may have contributed to the host partitioning pattern observed between enenterids and gyliauchenids.

AbstractThe taxonomy of the Asian genera of the subfamily Betylobraconinae, a small and understudied group within the hymenopteran family Braconidae, is revised. A new genus exclusively from the Asian region, Asiabregma gen. nov., containing three species (A. ryukyuensis sp. nov. (type species, Japan and Malaya), A. makiharai sp. nov. (Japan) and A. sulaensis (van Achterberg), comb. nov. (Indonesia)) is described. One new species of Aulosaphobracon, A. striatus sp. nov. from Vietnam, and one of Facitorus, F. amamioshimus sp. nov. from Japan, are also described. Based on molecular phylogenetic analyses using COI mtDNA and 28S rRNA sequences, the three genera previously placed in the tribe Facitorini, Facitorus, Conobregma and Jannya, together with Asiabregma gen. nov., are transferred to the rogadine tribe Yeliconini.

Orange Color

Crocinoboletus is described as a new genus of Boletaceae to accommodate Boletus rufoaureus and B. laetissimus, characterized by its brilliant orange color of basidiomata caused by the presence of unusual boletocrocin polyene pigments, bluish olivaceous staining of all parts when bruised, smooth basidiospores, and the pileipellis which has an interwoven trichoderm at the middle part of the pileus and a cutis at the margin of the pileus. Prior molecular phylogenetic analyses also confirmed the two taxa are not members of the genus Boletus s.s., but form a well-supported generic lineage within Boletaceae. Consequently a description, color photos of fresh basidiomata, line-drawings of microstructures and a comparison of Crocinoboletus with allied taxa are presented.

Coccoid green algae are abundant in subaerial habitats, but they are largely unexplored because of their morphological uniformity. Several new genus-level lineages have recently been described on the basis of molecular data. In this study, a coccoid green alga was isolated from surface soil in Zhoukou, Henan Province, China, and the cultured cells were described using light and electron microscopy. The ellipsoidal cell had smooth cell wall and parietal chloroplast with a pyrenoid surrounded by a starch envelope. Reproduction occurred by formation of 2‒16 autospores. Molecular phylogenetic analyses based on the nuclear 18S rDNA gene and the chloroplast ribulose-bisphosphate carboxylase gene (rbcL) indicated that this coccoid green alga represents a new lineage of the Watanabea clade (Trebouxiophyceae, Chlorophyta). Here, we describe this organism as a new genus and species, Polulichloris henanensis, gen. et sp. nov.

Sequence data (COI-5P and rbcL) for North American members of the tribe Pterosiphonieae were compared with collections from around the world. Phylogenetic analyses resolved Pterosiphonia as polyphyletic and many species required transfer to other genera. In our analyses Pterosiphonia sensu stricto included only the type species P. cloiophylla (C. Agardh) Falkenberg and P. complanata (Clemente) Falkenberg, as well as the South African species P. stegengae sp. nov. A new genus, Xiphosiphonia gen. nov., was described for X. ardreana (Maggs & Hommersand) comb. nov., X. pennata (C. Agardh) comb. nov., and X. pinnulata (Kützing) comb. nov. Some Asian, European and North American species previously attributed to Pterosiphonia were transferred to Symphyocladia including S. baileyi (Harvey) comb. nov., S. dendroidea (Montagne) comb. nov., S. plumosa nom. nov. (for P. gracilis Kylin), and S. tanakae (S. Uwai & M. Masuda) comb. nov. We also described two new North American species, Symphyocladia brevicaulis sp. nov. and S. rosea sp. nov. Other species formed a well-supported clade for which the genus name Polyostea Ruprecht was resurrected. Included in Polyostea were P. arctica (J. Agardh) comb. nov., P. bipinnata (Postels & Ruprecht) Ruprecht, P. hamata (E.S. Sinova) comb. nov., and P. robusta (N.L. Gardner) comb. nov.

Background The rich rodent assemblages from the Eocene–Oligocene deposits of the Jebel Qatrani Formation (Fayum Depression, Egypt) have important implications for our understanding of the origin and paleobiogeography of Hystricognathi, a diverse clade that is now represented by the Afro-Asiatic Hystricidae, New World Caviomorpha, and African Phiomorpha. Methods Here we present previously undescribed material of the enigmatic hystricognath clade Phiocricetomyinae, from two stratigraphic levels in the lower sequence of the Jebel Qatrani Formation—a new genus and species (Qatranimys safroutus) from the latest Eocene Locality 41 (~34 Ma, the oldest and most productive quarry in the formation) and additional material of Talahphiomys lavocati from that species’ type locality, early Oligocene Quarry E (~31–33.2 Ma). Results The multiple specimens of Qatranimys safroutus from L-41 document almost the entire lower and upper dentition, as well as mandibular fragments and the first cranial remains known for a derived phiocricetomyine. Specimens from Quarry E allow us to expand comparisons with specimens from Libya (late Eocene of Dur at-Talah and early Oligocene of Zallah Oasis) that have been placed in T. lavocati, and we show that the Dur at-Talah and Zallah specimens do not pertain to this species. These observations leave the Fayum Quarry E as the only locality where T. lavocati occurs.

The limbless, primarily soil-dwelling and tropical caecilian amphibians (Gymnophiona) comprise the least known order of tetrapods. On the basis of unprecedented extensive fieldwork, we report the discovery of a previously overlooked, ancient lineage and radiation of caecilians from threatened habitats in the underexplored states of northeast India. Molecular phylogenetic analyses of mitogenomic and nuclear DNA sequences, and comparative cranial anatomy indicate an unexpected sister-group relationship with the exclusively African family Herpelidae. Relaxed molecular clock analyses indicate that these lineages diverged in the Early Cretaceous, about 140 Ma. The discovery adds a major branch to the amphibian tree of life and sheds light on both the evolution and biogeography of caecilians and the biotic history of northeast India—an area generally interpreted as a gateway between biodiversity hotspots rather than a distinct biogeographic unit with its own ancient endemics. Because of its distinctive morphology, inferred age and phylogenetic relationships, we recognize the newly discovered caecilian radiation as a new family of modern amphibians.
