Morphological And Molecular Data

In this paper, we describe the new genus and species Lollipopaia minuta from a tropical rain forest in Thailand. The ascomata were long beaked and seated on a pseudoparenchymatous stroma that was erumpent through the bark of a decaying branch. Mature ascomata were readily formed under laboratory conditions. Lollipopaia minuta had ascomatal walls forming a textura intricata in surface view and deliquescent paraphyses. The asci floated freely at maturity and had a nonstaining apical ring. These characters are found in the Diaporthales. However, the habit of the stroma combined with the filiform ascospores distinguished L. minuta from all known genera of the Diaporthales. Thus, a close relationship to taxa outside the Diaporthales was considered. Lollipopaia minuta was similar to Ophioceras or Pseudohalonectria in shape of the ascomata, asci, and ascospores. However, phylogenetic analyses based on small subunit ribosomal DNA sequences confirmed the placement of L. minuta within the Diaporthales with 100% bootstrap support. A closest relative within the Diaporthales was not determined.Key words: Magnaporthaceae, microfungi, taxonomy, tropical mycology.

Seed Testa

Sinalliaria is described here as a new genus of the family Brassicaceae from eastern China, based on the morphological characters and molecular sequences. Sinalliaria differs from the related genus Orychophragmus in having basal leaves petiolate, simple or rarely with 1‒3 lateral lobes (not pinnatisect); cauline leaves petiolate, cordate at base (not sessile, auriculate or amplexicaul at base); petals obovate to narrowly obovate, claw inconspicuous (not broadly obovate, with a claw as along as sepal); siliques truncate (not long-beaked) at apex. The microscopic characters of seed testa also show significant differences between Sinalliaria and Orychophragmus. Phylogenetic evidence from DNA sequences of nuclear ribosomal ITS and plastid region trnL-trnF indicates that Sinalliaria is a distinct group related to Orychophragmus and Raphanus, but these three genera do not form a clade. The new genus Sinalliaria is endemic to eastern China and has only one species and one variety. The new combinations, S. limprichtiana (Pax) X. F. Jin, Y. Y. Zhou & H. W. Zhang and S. limprichtiana var. grandifolia (Z. X. An) X. F. Jin, Y. Y. Zhou & H. W. Zhang are proposed here.

Grammatuslabyrinthinusgen. et sp. nov. is proposed based on DNA sequences data and morphological characteristics. It is known so far from southern, tropical China. The new species is characterised by an annual, resupinate basidiocarp with a shallow, subporoid hymenophore, a hymenium restricted to the bottom of the tubes, a dimitic hyphal system, presence of encrusted skeletocystidia and dendrohyphidia, longitudinally septate basidia and smooth, oblong-ellipsoid to cylindrical, acyanophilous basidiospores. Phylogenetic analyses based on ITS + nLSU DNA sequences data indicate that G.labyrinthinus belongs to Auriculariaceae in which it has an isolated position. Phylogenetic inferences show G.labyrinthinus to be related to Heteroradulum. However, the ITS sequences similarity between G.labyrinthinus and H.kmetii, the type species of Heteroradulum, were 89.84% and support the establishment of the new genus. Inversely, Heteroradulumsemis clustered with G.labyrinthinus with strong support and it is transferred to Grammatus.

The cynipid inquilines genus Saphonecrus is known to be a polyphyletic group with distinct lineages. One lineage is associated with Synophrus in the Western Palaearctic on section Cerris oaks. Another involves the type species of Saphonecrus, S. connatus, and represents a distinct and probably early-diverging lineage with a Palaearctic distribution on white oaks. The third main lineage is predominantly Asian, and associated with Quercus subgenus Cyclobalanopsis and Quercus section Cerris and the oak-related Fagaceae including Lithocarpus. This third lineage shows large diversity, and includes the genus Ufo, the European lineage of S. undulatus and S. haimi, and the herein described new genus, Lithosaphonecrus Tang, Melika & Bozsó, known from Taiwan and China, with four new species: L. formosanus Melika & Tang, L. dakengi Tang & Pujade-Villar, L. huisuni Tang, Bozsó & Melika and L. yunnani Tang, Bozsó & Melika. All the four described species are associated only with Lithocarpus. Descriptions, diagnoses, biology, and host associations for the new genus and species are given, as well as a key to species and cynipid inquilines genera. All taxa are supported by morphological and molecular data.

A new genus is described to accommodate Neodicranella hamulosa, a novel species resolved in the family Aongstroemiaceae, from the Monchiquense district in SW Portugal. Characterized by its small size, erect spreading to subsecund non-sheathing leaves, plane bistratose leaf margins, and rhizoidal gemmae with slightly protruberant cells, it differs from all other European Dicranellaceae in the uniquely patterned distal peristome segments with backward-pointing papillae resembling hooked barbs. The species appears to be endemic to the sub-Mediterranean bioclimatic zone, in wooded biomes where humidity remains relatively high throughout the year. Morphological and molecular data strongly support the singularity of this new taxon. The species is illustrated by photomicrographs and SEM, and its ecology and conservation are discussed.

Morphological And Molecular Data

The Neotropical frog genus Cryptobatrachus includes six currently recognized species distributed throughout the northern Andes in Colombia and Venezuela. Cryptobatrachus conditus, C. pedroruizi, and C. remotus were described from the Colombian and Venezuelan slopes of the Serranía del Perijá. Due to the great morphological similarity among these species, we re-assess their taxonomic status based on morphological and molecular data from types, topotypes, and specimens from localities referred to in the original descriptions of these species. Morphometric comparisons showed that all these species are virtually indistinguishable, although some subtle qualitative differences in morphological traits distinguish C. conditus from the other species. Phylogenetic analyses of DNA sequences found that C. remotus and C. pedroruizi are not reciprocally monophyletic and exhibit low genetic divergence (< 1 %). Therefore, C. remotus should be considered a junior synonym of C. pedroruizi. This work stresses the importance of comprehensive taxon sampling in poorly explored areas, especially between neighbouring countries.

Intensive Sampling

The phylum Perkinsozoa is known as an exclusively parasitic group within alveolates and is widely distributed in various aquatic environments from marine to freshwater environments. Nonetheless, their morphology, life cycle, the identity of the host, and physiological characteristics remain still poorly understood. During intensive sampling along the west coast of Korea in October and November 2017, a new parasitoid, which shares several characteristics with the extant families Perkinsidae and Parviluciferaceae, was discovered and three strains of the new parasitoid were successfully established in cultures. Cross-infection experiments showed that among the examined planktonic groups, only dinoflagellates were susceptible to the new parasitoid, with infections observed in species belonging to eight genera. Even though the new parasitoid shared many morphological and developmental characteristics with other Perkinsozoan parasites, it differed from them by its densely packed trophocyte structure without a large vacuole or hyaline material during the growth stage. These characteristics are common among Parviluciferaceae members. Furthermore, through palintomic extracellular sporogenesis, it produced characteristic interconnected sporocytes resembling a string of beads. Phylogenetic analyses based on the small subunit and large subunit ribosomal DNA sequences revealed that the new parasitoid was distantly related to the family Parviluciferaceae and was more closely related to the families Perkinsidae and Xcellidae. Morphological, ultrastructural, and molecular data on the new parasitoid raised the need to erect a new family, i.e., Pararosariidae, within the phylum Perkinsozoa with Pararosarium dinoexitiosum gen. et sp. nov. as the type species. The isolation and establishment in culture of the new parasitoid outside the family Parviluciferaceae in the present study would contribute to the better understanding of the diversity of Perkinsozoan parasites and provide useful material for comparisons to other parasite species in the further study.

Blastopathes medusa gen. nov., sp. nov., is described from Kimbe Bay, Papua New Guinea, based on morphological and molecular data. Blastopathes, assigned to the Antipathidae, is a large, mythology-inspiring black coral characterized by clusters of elongate stem-like branches that extend out at their base and then curve upward. Colonies are not pinnulate and contain single branches, which could represent new branch cluster formations. Morphological and molecular (mitochondrial DNA and targeted capture of nuclear loci) evidence supporting the establishment of a new genus is discussed. This is the first study to utilize the target capture of ultraconserved elements (UCEs) and exonic loci to elucidate phylogenetic relationships among black corals and to identify and place a new genus and species.

Commensal Relationship

Birds harbour a wide array of other taxa in their nests or in their plumage, which either have an ectoparasitic or commensal relationship with the host. We report on the discovery of a cheliferid pseudoscorpion found in the plumage and nests of the sociable weaver bird (Philetairus socius) in southern Africa. The nests of these communal birds are the largest of any bird, and may contain up to 500 individuals. The pseudoscorpion is likely to have a mutualistic relationship with the birds, most likely preying on other small invertebrates in the nests. Molecular data derived from two populations of the pseudoscorpion found divergence levels of 1.1% in cytochrome oxidase 1 (CO1), and an analysis of CO1 and two rRNA genes (18S and 28S) found a close relationship with Chelifer and Parachelifer in the tribe Cheliferini, which is supported by the morphology of the male genitalia. The molecular analysis also suggests that Beierius may not belong to the Cheliferini. The pseudoscorpion found in association with the sociable weaver represents a new genus and species, Sociochelifer metoecus Harvey, sp. nov.

AbstractA new genus and species of nematode,Tziminema unachin. gen., n. sp. is described from the caecum and colon of Baird's tapirTapirus bairdii(Gill, 1865), found dead in the Reserva de la Biósfera El Triunfo, Chiapas State, in the Neotropical realm of Mexico.Tzimineman. gen. differs from the other nine genera included in the Strongylinae by two main characteristics: having 7–9 posteriorly directed tooth-like structures at the anterior end of the buccal capsule, and the external surface of the buccal capsule being heavily striated. Phylogenetic analyses of the DNA sequences of the mitochondrial cytochromecoxidase and nuclear DNA, including a partial sequence of the internal transcribed spacer 1, 5.8S and a partial sequence of the internal transcribed spacer 2 of the new taxon, confirmed its inclusion in Strongylinae and its rank as a new genus.
