Monograph of the Afrotropical species of Scelio Latreille (Hymenoptera,Platygastridae), egg parasitoids of acridid grasshoppers (Orthoptera,Acrididae)

The genus Scelio is a cosmopolitan and speciose group of solitary parasitoids of the eggs of short-horned grasshoppers (Orthoptera: Acrididae). A number of these hosts are important pests, including plague locusts of the genus Schistocerca. Species of Scelio are recognized as potentially important biological control agents, but this possibility has yet to be fully realized, in part because the species-level taxonomy is still incompletely developed. The species of the pulchripennis group have been recently revised. As a continuation of this effort, here we revise the Afrotropical species of Scelio, excluding the pulchripennis species group. Sixty two (62) species are treated, 48 of which are new. Species are classified into the following species groups: ernstii (12 species, 9 new), howardi (23 species, 19 new), ipomeae (6 species, 5 new), irwini (4 species, 3 new), simoni (3 new species) and walkeri (12 species, 9 new). Keys to species groups and to the species within each group are provided. New species described are: S. albatus Yoder, sp. n., S. aphares Yoder, sp. n., S. apospastos Yoder, sp. n., S. ardelio Yoder, sp. n., S. aurantium Yoder, sp. n., S. balo Valerio & Yoder, sp. n., S. bayanga Yoder, sp. n., S. bubulo Yoder, sp. n., S. cano Yoder, sp. n., S. clypeatus Yoder, sp. n., S. concavus Yoder, sp. n., S. copelandi Yoder, sp. n., S. crepo Yoder, sp. n., S. destico Yoder, sp. n., S. dupondi Yoder, sp. n., S. effervesco Yoder, sp. n., S. erugatus Yoder, sp. n., S. exophthalmus Yoder, sp. n., S. fremo Valerio & Yoder, sp. n., S. gemo Yoder, sp. n., S. grunnio Yoder, sp. n., S. harinhalai Yoder, sp. n., S. igland Yoder, sp. n., S. impostor Yoder, sp. n., S. irwini Yoder, sp. n., S. janseni Yoder, sp. n., S. latro Yoder, sp. n., S. memorabilis Yoder, sp. n., S. modulus Yoder, sp. n., S. mutio Yoder, sp. n., S. ntchisii Yoder, sp. n., S. parkeri Yoder, sp. n., S. phaeoprora Yoder, sp. n., S. pilosilatus Yoder, sp. n., S. pipilo Yoder, sp. n., S. quasiclypeatus Yoder, sp. n., S. retifrons Yoder, sp. n., S. ructo Yoder, sp. n., S. scomma Yoder, sp. n., S. simoni Yoder, sp. n., S. simonolus Yoder, sp. n., S. somaliensis Yoder, sp. n., S. susurro Yoder, sp. n., S. tono Yoder, sp. n., S. transtrum Yoder, sp. n., S. tritus Yoder, sp. n., S. ululo Yoder, sp. n., S. vannoorti Valerio & Yoder, sp. n. The following species are redescribed: S. afer Kieffer, S. chapmani Nixon, S. howardi Crawford, S. ipomeae Risbec, stat. n., S. mauritanicus Risbec, S. philippinensis Ashmead, S. remaudierei Ferrière, S. striatus Priesner,S. taylori Nixon, and S. zolotarevskyi Ferrière. The genus Lepidoscelio Kieffer is treated as a junior synonym of Scelio Latreille, syn. n.; its type species, Lepidoscelio fuscipennis Kieffer, 1905 is transferred to Scelio, renamed Scelio obscuripennis Johnson, nom. n. (preoccupied by Scelio fuscipennis Ashmead, 1887), and redescribed. The following additional species are transferred from Lepidoscelio to Scelio: S. cayennensis (Risbec), comb. n., S. insularis Ashmead, rev. comb., S. luteus (Cameron), comb. n., S. thoracicus Ashmead, rev. comb. Lectotypes are designated for S. africanus Risbec, S. ipomeae Risbec, S. mauritanicus Risbec, S. remaudierei Ferrière, S. sudanensis Ferrière, and S. zolotarevskyi Ferrière. Scelio gaudens Nixon is a junior synonym of Scelio striatus Priesner, syn. n.; Scelio africanus Risbec and Scelio clarus Fouts are both junior synonyms of Scelio afer Kieffer, syn. n.; Scelio sudanensis Ferrière and Scelio cheops Nixon are both junior synonyms of Scelio zolotarevskyi Ferrière, syn. n.; Scelio cahirensis Priesner is a junior synonym of Scelio mauritanicus Risbec, syn. n. The name Scelio chapmanni Nixon is an incorrect original spelling, requiring an emendation to S. chapmani.

Integrative revision of the giant pill-millipede genus Sphaeromimus from Madagascar,with the description of seven new species (Diplopoda,Sphaerotheriida, Arthrosphaeridae)

The Malagasy giant pill-millipede genus Sphaeromimus de Saussure & Zehntner, 1902 is revised. Seven new species, S. titanus sp. n., S. vatovavy sp. n., S. lavasoa sp. n., S. andohahela sp. n., S. ivohibe sp. n., S. saintelucei sp. n., and S. andrahomana sp. n. were discovered, in one case with the help of sequence data, in the rainforests of southeastern Madagascar. The species are described using light- and scanning electron microscopy. A key to all 10 species of the genus is presented. All but one (S. andohahela) of the newly discovered species are microendemics each occurring in isolated forest fragments. The mitochondrial COI barcoding gene was amplified and sequenced for 18 Sphaeromimus specimens, and a dataset containing COI sequences of 28 specimens representing all Sphaeromimus species (except S. vatovavy) was analyzed. All species are genetically monophyletic. Interspecific uncorrected genetic distances were moderate (4–10%) to high (18–25%), whereas intraspecific variation is low (0–3.5%). Sequence data allowed the correct identification of three colour morphs of S. musicus, as well as the identity of a cave specimen, which although aberrant in its morphology and colouration, was genetically identical to the holotype of S. andrahoma.     

Taxonomy and phylogeny of two poorly studied genera of marine oligotrich ciliates including descriptions of two new species: Cyrtostrombidium paraboreale sp. n. and Apostrombidium orientale sp. n. (Ciliophora: Spirotrichea)

Although it is widely recognized that oligotrich ciliates are the dominant constituent of microzooplankton communities and perform key functions in energy flow and material cycling in marine microbial food webs, knowledge of their diversity is scant. In the present study, we investigate the oligotrich genera, Cyrtostrombidium and Apostrombidium, with emphasis on their morphology and evolutionary relationships. Three isolates were collected from coastal waters of northern and southern China including two new species, viz., Cyrtostrombidium paraboreale sp. n., Apostrombidium orientale sp. n., and Apostrombidium pseudokielum Xu et al., 2009. Cyrtostrombidium paraboreale sp. n. is characterized by possessing 64–98 cytopharyngeal rods and two macronuclear nodules. Apostrombidium orientale sp. n. is characterized by its somatic kinety consisting of five fragments including a horizontally orientated subterminal fragment and possessing conspicuously long dorsal cilia. Apostrombidium pseudokielum is redescribed based on the new population and a re-examination of the type material. Phylogenetic analyses were performed for the subclass Oligotrichia, incorporating SSU rRNA gene sequences of the three species investigated here. The results indicate that the genus Cyrtostrombidium is monophyletic with C. paraboreale sp. n. occupying the basal position. The genus Apostrombidium is not monophyletic as Varistrombidium kielum is nested within it.     

Australian Assassins, Part III: A review of the Assassin Spiders (Araneae, Archaeidae) of tropical north-eastern Queensland

The assassin spiders of the family Archaeidae from tropical north-eastern Queensland are revised, with eight new species described from rainforest habitats of the Wet Tropics bioregion and Mackay-Whitsundays Hinterland: Austrarchaea griswoldi sp. n., Austrarchaea hoskini sp. n., Austrarchaea karenae sp. n., Austrarchaea tealei sp. n., Austrarchaea thompsoni sp. n., Austrarchaea wallacei sp. n., Austrarchaea westi sp. n. and Austrarchaea woodae sp. n. Specimens of the only previously described species, Austrarchaea daviesae Forster & Platnick, 1984, are redescribed from the southern Atherton Tableland. The rainforests of tropical eastern Queensland are found to be a potential hotspot of archaeid diversity and endemism, with the region likely to be home to numerous additional short-range endemic taxa. A key to species complements the taxonomy, with maps, natural history information and conservation assessments provided for all species.

New Kinorhyncha from Florida coastal waters

Four new species of Kinorhynchs are described from the West Atlantic coast off Fort Pierce, Florida, USA. They are the following: Antygomonas gwenae n. sp., Echinoderes riceae n. sp., Echinoderes adrianovi n. sp. and Pycnophyes norenburgi n. sp. All species were collected at the same locality called “20 miles station.” Samples were processed for standard granulometric data, yielding an estimated average particle diameter of 250 μm. The diagnostic characters and the general morphology of the new species are discussed in depth as well as the diversity and distribution of Kinorhyncha in the area.

The Ammonia Oxidizing and Denitrifying Prokaryotes Associated with Sponges from Different Sea Areas

Marine sponges have been suggested to play an important role in the marine nitrogen cycling. However, the role of sponge microbes in the nitrogen transformation remains limited, especially on the bacterial ammonia oxidization and denitrification. Hence, in the present study, using functional genes (amoA, nirS, nirK, and nxrA) involved in ammonia oxidization and denitrification and 16S rRNA genes for specific bacterial groups as markers, phylogenetically diverse prokaryotes including bacteria and archaea, which may be involved in the ammonia oxidization and denitrification processes in sponges, were revealed in seven sponge species. Ammonia oxidizers were found in all species, whereas three sponges (Placospongia sp., Acanthella sp., and Pericharax heteroraphis) harbor only ammonia-oxidizing bacteria (AOB), two sponges (Spirastrellidae diplastrella and Mycale fibrexilis) host only ammonia-oxidizing archaea (AOA), while the remaining two sponges (Haliclona sp. and Lamellomorpha sp.) harbor both AOB and AOA. S. diplastrella and Lamellomorpha sp. also harbor denitrifying bacteria. Nitrite reductase gene nirK was detected only in Lamellomorpha sp. with higher phylogenetic diversity than nirS gene observed only in S. diplastrella. The detected functional genes related to the ammonia oxidization and nitrite reduction in deep-sea and shallow-water sponges highlighted the potential ecological roles of prokaryotes in sponge-related nitrogen transformation.     

Novel diversity within Roseofilum (Desertifilaceae,Cyanobacteria) from marine benthic mats with description of four new species

Benthic cyanobacterial mats (BCMs) are natural phenomena in marine environments. Reports of BCMs occurring across coastal marine environments have increased, partly driven by nutrient loading and climate change; thus, there is a need to understand the diversity involved in the proliferations and potential toxicity of the BCMs. Furthermore, marine cyanobacterial mats are observed growing on and affecting the health of corals with one specific cyanobacterial genus, Roseofilum, dominating the microbial mats associated with black band disease (BBD), a destructive polymicrobial disease that affects corals. To explore the diversity of Roseofilum, cyanobacterial mats from various marine habitats were sampled, and individual isolates were identified based on morphology, 16S rRNA gene phylogenies, 16S–23S ITS rRNA region sequence dissimilarities, and phylogenomics. Four novel species of Roseofilum were isolated from benthic marine mats, three from the coasts of Florida, United States (R. capinflatum sp. nov., R. casamattae sp. nov., and R. acuticapitatum sp. nov.) and one from the coast of France (R. halophilum sp. nov.). Our analyses revealed that Roseofilum associated with coral BBD and those not associated with corals but rather from coastal benthic mats are systematically distinct based on both phylogenetic and phylogenomic analyses. Enzyme-linked immunosorbent assay (ELISA) and LC–MS data indicated that microcystin production was found in one of the four species.     

New species of Psilotrema and Sphaeridiotrema (Psilostomidae Odhner, 1913) in the east Asian region: Morphology of developmental stages and genetic data

Morphological and genetic data have been obtained for five new East Asian species of the Psilostomatidae. The life cycle of Psilotrema limosum n. sp. was carried out using Parafossarulus manchouricus as the first intermediate host. Compared with the East Asian species of the genus, these worms differ in morphometric characters in both the cercarial and adult stages. Its validity was also confirmed by the 28S rRNA gene data. Data on the life cycle and morphology of developmental stages of Sphaeridiotrema ussuriensis n. sp. and Sphaeridiotrema aziaticus n. sp. were also obtained. Cercariae of these species are found in Parafossarulus and Boreoelona snails, respectively. Sphaeridiotrema ussuriensis n. sp., like Sphaeridiotrema monorchis in China, has one testis, while S. aziaticus n. sp. has two testes. In addition, S. monorchis from Vietnam and Sphaeridiotrema spinoacetabulum from the Russian southern Far East are justified as belonging to the new species named Sphaeridiotrema vietnamensis n. sp. and Sphaeridiotrema pyriforme n. sp., respectively. This proposition is based on the morphology of developmental stages, the list of the first intermediate hosts and the 28S rRNA gene data. Analysis of the phylogenetic relationships within Psilostomatidae revealed three clusters, including taxa with different life cycles strategies. Sphaeridiotrema was also divided into two groups, which combine species according to their intermediate hosts and geographical localisation.     

New species of syringoporids from Eifelian deposits of the Subpolar Ural Mountains

A high diversity of tabulate corals in Eifelian deposits of the Syv“yu River basin (Subpolar Urals) is reported for the first time. Most of the corals are represented by colonies of syringoporids. Five new species Syringopora parva sp. nov., S. insueta sp. nov., S. indecora sp. nov., Tetraporinus syvjuensis sp. nov., and Armalites serotinus sp. nov. are described.     

The taxonomic accounts of the genus Symmorphus Wesmael (Hymenoptera,Vespidae, Eumeninae) from China,with descriptions of three new species

In this study, we recognize and review a total of 19 species of the genus Symmorphus Wesmael from China. We also provide a key to these species. Three new species are described and illustrated, namely Symmorphus (Symmorphus) tianchiensis Li & Chen, sp. n., S. (S.) cavatus Li & Chen, sp. n., and S. (S.) nigriclypeus Li & Chen, sp. n. The following four species are newly recorded from China: Symmorphus (S.) fuscipes (Herrich-Schaeffer), S. (S.) lucens (Kostylev), S. (S.) sublaevis Kostylev, and S. (S.) violaceipennis Giordani Soika. In addition, we map the species geographical distributions in China of these 19 species. Type specimens of these three new species are deposited in Chongqing Normal University and Yunnan Agricultural University.     

Actinobacterial community and diversity in rhizosphere soils of Aquilaria crassna Pierre ex Lec assessed by RT-PCR and PCR-DGGE

The actinobacterial community in rhizospheres of eaglewood (Aquilaria crassna Pierre ex Lec) was analyzed using culture-independent methods of RT-PCR and PCR DGGE of 16S rRNA gene. We conducted the experiments to investigate the difference in diversity and community structure of actinobacteria with respect to sampling sites and seasons and to determine effect of plant species on selection of rhizosphere community from different sampling sites. Total genomic DNA and RNA were extracted from rhizosphere soils collected from two plantations in Phetchabun province and one plantation in each Nakhonnayok province, Rayong province and Chiang Mai province of Thailand during dry and rainy seasons. The UPGMA dendrogram generated from DGGE fingerprints showed that the actinobacterial community was separated corresponding to sampling sites, suggesting sampling sites effect. The shift in community and diversity between two seasons was detected in all sampling sites. RNA-based analyses showed that several actinobacterial groups appeared to be ubiquitous but different in metabolic activity in different environments. Species diversity (S) and simple indexes (I) indicate the increase in species diversity of actinobacteria from all sampling sites in rainy season. Cloning and sequencing of 16S rRNA gene fragments obtained from DGGE bands revealed that 14 of 40 dominant species of actinobacteria in the rhizospheres of this plant belonged to uncultured actinobacteria. Besides the uncultured actinobacteria, Nocardioides sp., Streptomyces sp., Mycobacterium sp., Rhodococcus sp. and Actinoplanes sp. were indentified and frequently found more than other genera.
