Peridinium Cinctum

The vast majority not only of dinophytes, but also of Peridiniales, live in the marine environment, and some 350 (out of ca 2.500) species are present in freshwater habitats (Mertens et al. 2012). Many freshwater Peridiniales constitute small and only distantly related species groups embedded in predominantly marine clades (e.g., Apocalathium, Chimonodinium, Naiadinium in the Thoracosphaeraceae; species assigned to “Peridiniopsis” in the Kryptoperidiniaceae; Zhang et al. 2011b, Gottschling & Söhner 2013, Annenkova et al. 2015; Fig. 1). However, the most distinguished freshwater group of the Peridiniales are the Peridiniaceae including the type species, Peridinium cinctum, and other frequently encountered species such as Peridinium bipes, Peridinium volzii and Peridinium willei.

Twenty-two new species of the genus Eviulisoma Silvestri, 1910, from the Eastern Arc Mountains, Tanzania, are described: E. acaciae sp. nov., E. aequilobatum sp. nov., E. akkariae sp. nov., E. angulatum sp. nov., E. articulatum sp. nov., E. biquintum sp. nov., E. breviscutum sp. nov., E. cetafi sp. nov., E. chitense sp. nov., E. commelina sp. nov., E. coxale sp. nov., E. ejti sp. nov., E. grumslingslak sp. nov., E. kalimbasiense sp. nov., E. navuncus sp. nov., E. nessiteras sp. nov., E. ottokrausi sp. nov., E. paradisiacum sp. nov., E. sternale sp. nov. and E. zebra sp. nov. from the Udzungwa Mts, E. culter sp. nov. from the Rubeho Mts and E. kangense sp. nov. from the Kanga Mts. Eviulisoma kwabuniense Kraus, 1958, and E. dabagaense Kraus, 1958, both from the Udzungwa Mts, are redesribed based on new material. Notes are provided on E. iuloideum (Verhoeff, 1941) based on type material. Eoseviulisoma Brolemann, 1920, is synonymized under Eviulisoma, based on newly collected material of E. julinum (Attems, 1909), type species of Eoseviulisoma. New material of Suohelisoma ulugurense Hoffman, 1964, type species of Suohelisoma Hoffman, 1964, has revealed that the gonopod structure is more similar to that of Eviulisoma than originally thought, but Suohelisoma is retained as a valid genus. Four species groups are recognized among Eviulisoma species from the Udzungwa Mts, but the need for a revision of the entire genus is emphasized. Two types of epizootic fungi are recorded from Eviulisoma spp., and an enigmatic amorphous mass, which may be a kind of plugging substance, is recorded from the gonopod tips and excavated sixth sternum of several species.

The genus Metallactus has been controversial since its introduction due to the ambiguous nature of the original diagnosis. This has caused some confusion in the taxonomy of Neotropical Pachybrachina. In this work the morphology of endophallus, which is useful for the characterization of species groups in several groups of Coleoptera, including Cryptocephalinae, has been analyzed. This has proven to be a good resource also in the taxonomic treatment of the species belonging to the genus Metallactus. After a careful survey on most of the species described so far, the endophallus shape in Metallactus turned out to be remarkably distinctive and very promising in the delimitation of species groups. The present work includes: a) a new diagnosis of the genus Metallactus on the basis of the aedeagal anatomy; b) the designation of the type species of the nominal genus; c) the revision of a first species-group of the genus, including the type species, hereinafter called Metallactus kollari species-group. Before this revision, catalogues had been reporting 13 species attributable to this group, in the present work three species have been synonymized and seven have been described as new to science. Therefore, the group includes 17 species. The species described as new are: Metallactus rileyi n. sp., M. bellatrix n. sp., M. longicornis n. sp.; M. londonpridei n. sp., M. regalini n. sp., M. bezoar n. sp., M. guarani n. sp. The new synonymies are as follows: Metallactus albipes Suffrian, 1866 (= M. nigrofasciatus Suffrian, 1866 n. syn.), M. albifrons Suffrian, 1866 (= M. flavofrontalis Jacoby, 1907 n. syn.), M. dodecastictus Suffrian, 1866 (= Griburius nigritarsis Jacoby, 1907 n. syn.). The lectotypes of all previously described species have been designated. The new synonymies, the name-bearing type fixations and designations and the nomenclatural acts have been critically discussed. An identification key for the species-group is also provided.

Genomic Characterization

A Gram-stain-negative, oxidase-positive, catalase-positive, aerobic, orange-pigmented, rod-shaped and non-motile bacterium designated strain MMS17-SY002T was isolated from island soil. The isolate grew at 20–37 °C (optimum, 30 °C), at pH 6.0–9.5 (optimum, pH 7) and in the presence of 0.5–4.0 % (w/v) NaCl (optimum, 2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MMS17-SY002T was mostly related to the genus Muriicola of the family Flavobacteriaceae and had highest sequence similarity of 96.82 % to Muriicola marianensis A6B8T and Muriicola jejuensis EM44T, but formed a distinct phylogenetic line within the genus. Chemotaxonomic analyses showed that menaquinone 6 was the predominant isoprenoid quinone, the major fatty acids were iso-C15 : 1 G and iso-C15 : 0, and the diagnostic polar lipid was phosphatidylethanolamine. The genomic DNA G+C content was 42.4 mol%. Strain MMS17-SY002T could be distinguished from related species by the combination of trypsin, α-chymotrypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase, α-galactosidase, β-galactosidase and β-glucosidase activities. The orthologous average nucleotide identity between the genomes of strain MMS17-SY002T and M. jejuensis and that between the strain and M. marianensis A6B8T were 73.26 and 73.33%, respectively, thus confirming the separation of the strain from related species at species level. Based on the phenotypic, phylogenetic, chemotaxonomic and genomic characterization, MMS17-SY002T should be recognized as a novel species of the genus Muriicola , for which the name Muriicola soli sp. nov. is proposed. The type strain is MMS17-SY002T (=KCTC 62790T=JCM 32370T).

The genus Chilecicada Sanborn, 2014 is shown to be a complex of closely related species rather than a monospecific genus. Chilecicada citatatemporaria Sanborn & Cole n. sp., C. culenesensis Sanborn & Cole n. sp., C. curacaviensis Sanborn & Cole n. sp., C. impartemporaria Sanborn & Cole n. sp., C. magna Sanborn & Cole n. sp., C. mapuchensis Sanborn n. sp., C. oraria Sanborn & Cole n. sp., C. parrajaraorum Sanborn n. sp., C. partemporaria Sanborn & Cole n. sp., C. pehuenchesensis Sanborn & Cole n. sp., C. trifascia Sanborn n. sp., C. trifasciunca Sanborn & Cole n. sp., and C. viridicitata Sanborn & Cole n. sp. are described as new. Chilecicada occidentis Walker, 1850 is re-described to facilitate separation of the new species from the only previously known species. Song and cytochrome oxidase I analysis available for most species support the separation of the new taxa from the type species of the genus. Known species distributions and a key to the species of the genus are also provided. The new species increases the known cicada diversity 61.9% to 34 species, 91.2% of which are endemic to Chile.

Abstract Parasesarma is a species-rich genus whose representatives are common in wetlands and mangroves of the Indo-Pacific. Morphologically, the genus is heterogeneous and has been postulated to constitute a polyphyletic taxon. In the present study, most species of Parasesarma are re-evaluated phylogenetically, using mitochondrial and nuclear molecular markers. The results show that the majority of the examined species cluster consistently with the type species Parasesarma plicatum. However, some species, among them the tree-climbing Parasesarma leptosoma, are clearly separated from this main clade of Parasesarma, forming a second stable monophyletic group, distinct from other known genera. Based on these results, and with additional support by morphological diagnoses highlighting consistent differences between the two species groups, we propose a new genus for the species clustering around P. leptosoma, proposing the new name Leptarma gen. nov.

First Time

Hypoxys is one of four subgenera of Edessa (Fabricius, 1787) together with Aceratodes (De Geer, 1773), Dorypleura (Lepeletier & Serville, 1825) and Edessa (Fabricius, 1787). This taxon has a very confusing taxonomy due to incorrect use of the names available, imprecise descriptions, and large number of very similar species. To illustrate the confusion, Hypoxys potentially includes a large number of species of Edessa, but actually contains only the type species, according to the most recent catalogue. The name E. quadridens Fabricius, 1803, type species of Hypoxys, was used for more than a century as a label to identify a large group of similar species. In this work we continue revising Edessa elevating Hypoxys to genus based on the following morphological characters: proximal part of costal margin black; evaporatorium with a deep notch on lateral margin; anterior arms of metasternal process acuminate; pygophore longer than wide and subrectangular or barrel-shaped in dorsal view; dorsal rim of pygophore well-projected, almost reaching posterolateral angles and finishing in a small lobe; and posterolateral angles of pygophore not developed. Hypoxys is being divided in four species groups to include 17 species transferred from Edessa. H. quadridens group comprises: Hypoxys quadridens (Fabricius, 1803) (type species), H. boerneri (Breddin, 1904) comb. nov., H. claricolor (Breddin, 1907) comb. nov., H. dolosus (Breddin, 1907) comb. nov., H. eburatulus (Breddin, 1907) comb. nov., H. necopinatus (Breddin, 1907) comb. nov., H. offuscatus (Breddin, 1907) comb. nov. and H. trabeculus (Breddin, 1907) comb. nov. H. triangularis group comprises: H. triangularis (Dallas, 1851) comb. nov. (type species), H. capito (Breddin, 1904) comb. nov. and H. subrastratus (Bergroth, 1891) comb. nov. H. oxyacanthus group comprises: H. oxyacanthus (Breddin, 1904) comb. nov. (type species), H. brachyacanthus (Breddin, 1904) comb. nov., H. infulatus (Breddin, 1904) comb. nov., H. leptacanthus (Breddin, 1904) comb. nov. and H. tragelaphus (Breddin, 1903) comb. nov. H. balteatus group comprises only H. balteatus (Walker, 1868) comb. nov. These groups of species will be useful to organize the new species of Hypoxys that will be described in upcoming papers. Descriptions, measurements, photos of genitalia of both sexes; photos in dorsal and ventral views of the species; and distribution maps are provided. Males of H. capito, H. claricolor, H. eburatulus, H. infulatus, and H. subrastratus are described for the first time. Female of H. necopinatus is described for the first time. Edessa jugalis is considered a junior synonym of H. quadridens; E. rimata a junior synonym of H. offuscatus; E. scabriventris and E. leprosula junior synonyms of H. triangularis; E. pachyacantha a junior synonym of H. tragelaphus; E. orba a junior synonym of E. oxyacanthus. A key to the species of Hypoxys is also provided.

Detection of previously unknown, dimorphic setal patterns on the carpus of the fifth thoracic endopod in types of Parvimysis bahamensis Brattegard, 1969, representing the type species of the genus Parvimysis Brattegard, 1969, required revision of this genus together with taxonomic verification of materials previously assigned to this species from all around the Caribbean. Study of this material together with new samples from marine waters of Curaçao led to the detection of five new species. Four of these species have a dimorphic carpus of the fifth endopod and are here described as P. pricei sp. nov., P. laminata sp. nov., P. brattegardi sp. nov., and P. ornata sp. nov. One species with non-dimorphic setal patterns is described as P. nuda sp. nov. Two species groups are defined based on structural differences of the carapace, mandibular and maxillary palpus, oostegites and telson: the P. bahamensis group with six species from marine waters of the Caribbean and an additional one from brackish-freshwaters of Surinam, versus the P. amazonica group with seven species from freshwaters of Amazonia. A key to the 14 species currently known from the genus Parvimysis is provided.

Freshwater Habitats

Semiaquatic bugs (Heteroptera, infraorder Gerromorpha) are distributed worldwide with approximately 1,600 described species. Most species live in various types of freshwater habitats, but a little more than 10% have colonised the marine environment. The Australian fauna constitutes a significantly higher percentage of marine species (about 25%) than in any other continent. Among these are the coral treaders, Hermatobates Carpenter, belonging to the Hermatobatidae, one of very few insect families that only include marine species. In this paper the two species of Hermatobates previously known from Australia are redescribed and H. armatus, sp. nov. from the Chesterfield Islands in the Coral Sea is added. The distribution of species known from Australia and New Caledonia is mapped, and a revised key to the eight species currently recognised in the genus is presented. Finally, the available knowledge about the biology and ecology of coral treaders is reviewed and discussed.

The type species of the genus Acidiella Hendel is A. longipennis Hendel, which is known as a widely distributed species in South East Asia. Specimens of A. longipennis are rarely found in insect collections, but I was able to examine a number of Myanmar specimens collected by R. Malaise during the Swedish Expedition in 1934, and reported as A. longipennis by M. Hering in 1938. As a result, three related species were sorted out from these specimens. They look very much alike except for the dorsal abdominal patterns (difficult to see in dried specimens) and postabdominal structures. I here provide detailed descriptions of and a key to A. longipennis, A. spinipenis, sp. nov., and A. kambaitiensis, sp. nov. They are here defined as the A. longipennis species group based on a single synapomorphy: vesica of glans ventrally with 7–9 tiny spines. This is a unique characteristic never found in any other species of the tribe Trypetini as well as the family Tephritidae. I am providing this information as a starting point to refine the currently confused concept of the genus Acidiella.
