The monotypic genus Latonius Kononova, 1982 (Platygastroidea, Scelionidae), was described from a single female specimen collected in southern Ukraine. It somewhat resembles Trissolcus Ashmead but has a distinctive claval formula. The only species in the genus, Latonius planus Kononova, 1982, is lacking any details regarding biology, sexual dimorphism, intraspecific variability, or distribution. Based on recently collected specimens the present study clarifies the position of Latonius within the Telenominae, provides a comprehensive description accompanied by high quality images, and compares Latonius and Trissolcus. Five molecular markers were amplified, and sequences of L. planus were analyzed using a data set for the molecular phylogeny of Telenominae (Taekul et al. 2014) and a molecular phylogeny of Trissolcus (Talamas et al. 2019). We dissected the metasoma, tarsi, antennae, and ovipositor and performed SEM imaging. The genera Latonius and Ioseppinella Mineo, O’Connor & Ashe, 2010, are treated as junior synonyms of Trissolcus and the type species of Latonius and Ioseppinella are considered to be conspecific (syn. nov.).

The genus Xylaplothrips is re-diagnosed, 11 species are listed as appropriately included in this genus of which three are new combinations from Haplothrips (X. acaciae; X. collyerae; X. gahniae). A further six species are listed as incertae sedis within Xylaplothrips and a key is provided to the four species of this genus known from Australia including X. anarsius sp.n. The genus Mesandrothrips is recalled from synonymy with Xylaplothrips, and a list is provided of 20 appropriately included species of which 14 are new combinations from Xylaplothrips (M. caliginosus; M. clavipes; M. darci; M. dubius; M. emineus; M. flavitibia; M. flavus; M. inquilinus; M. montanus; M. pictipes; M. pusillus; M. reedi; M. subterraneus; M. tener), and one is a new combination from Haplothrips (M. inquinatus). A key is provided to 10 species of this genus known from Australia, including three species transferred from Haplothrips, together with M. austrosteensia sp.n., M. googongi sp.n., M. kurandae sp.n., M. lamingtoni sp.n. and M. oleariae sp.n. The type species, M. inquilinus, is widespread across Southeast Asia as an invader of thrips galls, and Haplothrips darci Girault based on a single female from Queensland is considered closely related.

In the field of chemical safety, a named entity recognition (NER) model based on deep learning can mine valuable information from hazard and operability analysis (HAZOP) text, which can guide experts to carry out a new round of HAZOP analysis, help practitioners optimize the hidden dangers in the system, and be of great significance to improve the safety of the whole chemical system. However, due to the standardization and professionalism of chemical safety analysis text, it is difficult to improve the performance of traditional models. To solve this problem, in this study, an improved method based on active learning is proposed, and three novel sampling algorithms are designed, Variation of Token Entropy (VTE), HAZOP Confusion Entropy (HCE) and Amplification of Least Confidence (ALC), which improve the ability of the model to understand HAZOP text. In this method, a part of data is used to establish the initial model. The sampling algorithm is then used to select high-quality samples from the data set. Finally, these high-quality samples are used to retrain the whole model to obtain the final model. The experimental results show that the performance of the VTE, HCE, and ALC algorithms are better than that of random sampling algorithms. In addition, compared with other methods, the performance of the traditional model is improved effectively by the method proposed in this paper, which proves that the method is reliable and advanced.

Seven genera new to science, i.e.: Helmutiopsis, Huriopsis, Johnsheardia, Klauskalbia, Kudratovia, Kurokawia and Poeltonia of the Physciaceae are proposed for the ‘Rinodina’ atrocinerea, the ‘Rinodina’ xanthophaea, the ‘Rinodina’ cinnamomea, the ‘Heterodermia’ obscurata, the ‘Rinodina’ straussii, the ‘Anaptychia’ isidiata and the ‘Physconia’ grisea groups consequently that all form strongly supported monophyletic branches in a phylogeny analysis based on a combined matrix of nrITS and mtSSU sequences. Phylogenetic positions of species belonging to the genera Kashiwadia s. l., Leucodermia, Mischoblastia,Oxnerella, Phaeorrhiza s. l., Polyblastidium and Rinodinella s. l. are discussed. Oxnerella afghanica which for the first time recorded as parasitic lichen species from both epiphytic and saxicolous crustose lichens is designated as type species for the genus Oxnerella. Sequences of the recently described Physcia orientostellaris as well as Huriopsis xanthophaea and additional sequences of Kashiwadia aff. orientalis and Mischoblastia aff. oxydata are submitted to the GenBank. The positions of Polyblastidium casaterrinum from Costa Rica, ‘Rinodina’ efflorescens from Białowieża, Poland, and ‘Mischoblastia’ confragosula from Cambodia in the Physciaceae are confirmed in a phylogeny analysis based on the nrITS sequences. The presence of ‘extraneous mycobiont DNA’ in lichen associations is exemplified with earlier incorrect identifications of Heterodermia, Kashiwadia, Kurokawia,Oxnerella and Poeltonia specimens. Fifty-six new combinations are presented: Helmutiopsis alba (for Rinodina alba Metzler ex Arn.), Helmutiopsis aspersa (for Lecanora aspersa Borrer), Helmutiopsis atrocinerea (for Parmelia atrocinerea Fr.), Huriopsis chrysidiata (for Rinodina chrysidiata Sheard), Huriopsis chrysomelaena (for Rinodina chrysomelaena Tuck.), Huriopsis lepida (for Lecanora lepida Nyl.), Huriopsis luteonigra (for Rinodina luteonigra Zahlbr.), Huriopsis plana (for Rinodina plana H.

The Lepidoptera fauna of the island of Flores (Lesser Sunda Archipelago, Indonesia) shares a large proportion of endemic species, which may reach 80–100% in several groups (Zolotuhin & Witt 2005; Nässig et al. 2009; Zolotuhin 2009; Nässig & Bouyer 2010; Yakovlev 2015; Spitsyn & Potapov 2020; Spitsyn & Bolotov 2020). A plethora of new species was described from this island during the last 15 years, e.g. the tiger moth Spilarctia mikeli Bolotov, Kondakov & Spitsyn, 2018 (Zolotuhin & Witt 2005; Yakovlev 2006; Spitsyn & Bolotov 2020a, b, c). This species was described based on a single female specimen collected in West Flores (Bolotov et al. 2018). In the present paper, we describe the male of Spilarctia mikeli for the first time, and illustrate variability of marking patterns of both the male and the female of this species.

Species Descriptions

Abstract The genus Itunella Brady, 1896 has a troubled taxonomic past, partly because of paucity of its members, but mostly because of inadequate research. A lack of detail in species descriptions and redescriptions, absence of alternative methods for testing species hypotheses, combined with a notion that most marine and estuarine animals have wide distributions and enormous intraspecific variability, all resulted in blurring of some interspecific boundaries, synonymizing without examination of the type material, and founding species diagnoses on dubious characters. Itunella yeondeokensis sp. nov. is described here in great detail from a small sandy beach on the east coast of Korea. It differs from all reported and illustrated congeners by an extremely long inner apical seta on the third exopodal segment of second to fourth swimming legs. This is the second member of this genus from Korea, the first one being described from three estuaries also on the east coast. All other congeners are European species. An overview of all published species and records of this genus is provided, as well as a dichotomous key to valid species to aid in their identification. Itunella kieferi sp. nov. is a new name for a single female from Germany, previously reported as a member of a widely distributed and polymorphic species.

Community Clustering

In the last couple of decades, clustering has become a very crucial research problem in the data mining research community. Clustering refers to the partitioning of data objects such as records and documents into groups or clusters of similar characteristics. Clustering is unsupervised learning, because of unsupervised nature there is no unique solution for all problems. Most of the time complex data sets require explanation in multiple clustering sets. All the Traditional clustering approaches generate single clustering. There is more than one pattern in a dataset; each of patterns can be interesting in from different perspectives. Alternative clustering intends to find all unlike groupings of the data set such that each grouping has high quality and distinct from each other. This chapter gives you an overall view of alternative clustering; it's various approaches, related work, comparing with various confusing related terms like subspace, multi-view, and ensemble clustering, applications, issues, and challenges.

Current Classification

During the last decade, the classification system of chytrids has dramatically changed based on zoospore ultrastructure and molecular phylogeny. In contrast to well-studied saprotrophic chytrids, most parasitic chytrids have thus far been only morphologically described by light microscopy, hence they hold great potential for filling some of the existing gaps in the current classification of chytrids. The genus Zygorhizidium is characterized by an operculate zoosporangium and a resting spore formed as a result of sexual reproduction in which a male thallus and female thallus fuse via a conjugation tube. All described species of Zygorhizidium are parasites of algae and their taxonomic positions remain to be resolved. Here, we examined morphology, zoospore ultrastructure, host specificity, and molecular phylogeny of seven cultures of Zygorhizidium spp. Based on thallus morphology and host specificity, one culture was identified as Z. willei parasitic on zygnematophycean green algae, whereas the others were identified as parasites of diatoms, Z. asterionellae on Asterionella, Z. melosirae on Aulacoseira, and Z. planktonicum on Ulnaria (formerly Synedra). According to phylogenetic analysis, Zygorhizidium was separated into two distinct order-level novel lineages; one lineage was composed singly of Z. willei, which is the type species of the genus, and the other included the three species of diatom parasites. Zoospore ultrastructural observation revealed that the two lineages can be distinguished from each other and both possess unique characters among the known orders within the Chytridiomycetes. Based on these results, we accommodate the three diatom parasites, Z. asterionellae, Z. melosirae, and Z. planktonicum in the distinct genus Zygophlyctis, and propose two new orders: Zygorhizidiales and Zygophlyctidales.

New Synonymy

The golden orb-weaving spider genus Nephila Leach, 1815 currently has four representatives in India: Nephila dirangensis Biswas & Biswas, 2006, Nephila kuhlii (Doleschall, 1859), Nephila pilipes (Fabricius, 1793) and Nephila robusta Tikader, 1962 (World Spider Catalog 2020). While N. kuhlii has its type locality in Java (Doleschall 1859) and that of N. pilipes in Australasia (Fabricius 1781), N. dirangensis and N. robusta are both confined to India (World Spider Catalog 2020). Tikader (1962) described the species N. robusta based on a single female specimen collected in West Bengal. The original genitalic illustrations of this species, however, show close resemblance to that of N. pilipes, indicating its possible synonymy with the latter. To confirm the novelty of N. robusta, we examined its type specimen and the result is presented below. Additionally, we discuss the occurrence of colour morphs in the Indian populations of N. pilipes.
