A new species, Ropalidia daklak Bui, Mai & Nguyen, sp. nov., belonging to the plebeja-group of the genus Ropalidia Guérin-Méneville, 1831 is described and figured based on females and males from Vietnam. The nest structure of the new species is described, and an updated key is provided to all known species of the group. [ABSTRACT FROM AUTHOR]

Ropalidia amabala sp. nov. is described and compared to the known African species of this genus. In addition, the nest and nesting habits are described. This species demonstrates the nesting pattern previously recorded only in Madagascar, which includes nesting directly on a tree trunk and using lichen as the nest-building source material to blend in with the surrounding lichen patches. In contrast to the Malagasy species, which clean the nesting area of lichen, this new South African species constructs the nest in a clear area of the trunk between patches of lichen. This provides excellent visual concealment of the nest and suggests that visually driven predators are the primary selective factor. The morphology for both sexes of this species disagrees with known Malagasy species, suggesting that they are separate evolutionary lineages and hence that this nesting behaviour evolved independently.

Background: Discoveries of new species often depend on one or a few specimens, leading to delays as researchers wait for additional context, sometimes for decades. There is currently little professional incentive for a single expert to publish a stand-alone species description. Additionally, while many journals accept taxonomic descriptions, even specialist journals expect insights beyond the descriptive work itself. The combination of these factors exacerbates the issue that only a small fraction of marine species are known and new discoveries are described at a slow pace, while they face increasing threats from accelerating global change. To tackle this challenge, this first compilation of Ocean Species Discoveries (OSD) presents a new collaborative framework to accelerate the description and naming of marine invertebrate taxa that can be extended across all phyla. Through a mode of publication that can be speedy, taxonomy-focused and generate higher citation rates, OSD aims to create an attractive home for single species descriptions. This Senckenberg Ocean Species Alliance (SOSA) approach emphasises thorough, but compact species descriptions and diagnoses, with supporting illustrations and with molecular data when available. Even basic species descriptions carry key data for distributions and ecological interactions (e.g., host-parasite relationships) besides universally valid species names; these are essential for downstream uses, such as conservation assessments and communicating biodiversity to the broader public. New information: This paper presents thirteen marine invertebrate taxa, comprising one new genus, eleven new species and one re-description and reinstatement, covering wide taxonomic, geographic, bathymetric and ecological ranges. The taxa addressed herein span three phyla (Mollusca, Arthropoda, Echinodermata), five classes, eight orders and twelve families. Apart from the new genus, an updated generic diagnosis is provided for four other genera. The newly-described species of the phylum Mollusca are Placiphorella methanophila Vončina, sp. nov. (Polyplacophora, Mopaliidae), Lepetodrilus marianae Chen, Watanabe & Tsuda, sp. nov. (Gastropoda, Lepetodrilidae), Shinkailepas gigas Chen, Watanabe & Tsuda, sp. nov. (Gastropoda, Phenacolepadidae) and Lyonsiella illaesa Machado & Sigwart, sp. nov. (Bivalvia, Lyonsiellidae). The new taxa of the phylum Arthropoda are all members of the subphylum Crustacea: Lepechinella naces Lörz & Engel, sp. nov. (Amphipoda, Lepechinellidae), Cuniculomaera grata Tandberg & Jażdżewska, gen. et sp. nov. (Amphipoda, Maeridae), Pseudionella pumulaensis Williams & Landschoff, sp. nov. (Isopoda, Bopyridae), Mastigoniscus minimus Wenz, Knauber & Riehl, sp. nov. (Isopoda, Haploniscidae), Macrostylis papandreas Jonannsen, Riehl & Brandt, sp. nov. (Isopoda, Macrostylidae), Austroniscus indobathyasellus Kaiser, Kniesz & Kihara, sp. nov. (Isopoda, Nannoniscidae) and Apseudopsis daria Esquete & Tato, sp. nov. (Tanaidacea, Apseudidae). In the phylum Echinodermata, the reinstated species is Psychropotes buglossa E. Perrier, 1886 (Holothuroidea, Psychropotidae). The study areas span the North and Central Atlantic Ocean, the Indian Ocean and the North, East and West Pacific Ocean and depths from 5.2 m to 7081 m. Specimens of eleven free-living and one parasite species were collected from habitats ranging from an estuary to deep-sea trenches. The species were illustrated with photographs, line drawings, micro-computed tomography, confocal laser scanning microscopy and scanning electron microscopy images. Molecular data are included for nine species and four species include a molecular diagnosis in addition to their morphological diagnosis. The five new geographic and bathymetric distribution records comprise Lepechinella naces Lörz & Engel, sp. nov., Cuniculomaera grata Tandberg & Jażdżewska, sp. nov., Pseudionella pumulaensis Williams & Landschoff, sp. nov., Austroniscus indobathyasellus Kaiser, Kniesz & Kihara, sp. nov. and Psychropotes buglossa E. Perrier, 1886, with the novelty spanning from the species to the family level. The new parasite record is Pseudionella pumulaensis Williams & Landschoff, sp. nov., found in association with the hermit crab Pagurus fraserorum Landschoff & Komai, 2018. [ABSTRACT FROM AUTHOR]

The genus Elegansovella Hirschmann, 1989 (Mesostigmata: Uropodina: Urodinychidae) is resurrected for species of the Uroobovella elegans-group. This genus differs from the other taxa of Uroobovella Berlese, 1903 sensu lato based on the shape of the idiosoma and the caudal and dorsal setae. Three species from the Uroobovella elegans-group are transferred to the genus Elegansovella, as E. pectintata (Hirschmann, 1973), comb. nov., E. pectinatasimilis (Hiramatsu, 1980), comb. nov. and E. serangensis (Hiramatsu, 1980), comb. nov. The other seven species from this species group are transferred to Monstrobovella gen. nov., as M. crustosa (Vitzthum, 1926), comb. nov., M. enodis (Hiramatsu, 1985), comb. nov., M. faceta (Hiramatsu & Hirschmann, 1978), comb. nov., M. facetaoides (Hiramatsu & Hirschmann, 1978), comb. nov., M. imadatei (Hiramatsu, 1980), comb. nov., M. incerta (Hiramatsu & Hirschmann, 1978), comb. nov. and M. incertaoides (Hiramatsu & Hirschmann, 1978), comb. nov. The new genus differs from Elegansovella by the shape of the idiosoma and the shape of marginal and dorsal setae. Six Monstrobovella species occur in the Oriental Realm and only one species is known from the Neotropical region. The present paper contains the description of a second Neotropical species of Monstrobovella (M. mancocapaci sp. nov.) which was found in Peru. The new species differs from its Neotropical congener in the dorsal and marginal setation. [ABSTRACT FROM AUTHOR]

The Inonotus linteus complex, predominantly reported from East Asia, Mesoamerica and Caribbean countries, was circumscribed into Tropicoporus as one of the new genera, based on morphological and phylogenetic data. The present paper describes four new species of Tropicoporus from India. Morphological characteristics and phylogenetic analyses, based on ITS and nLSU data, delimited the new species, which are named T. cleistanthicola, T. indicus, T. pseudoindicus and T. tamilnaduensis. The pairwise homoplasy index (PHI) test was done to confirm the distinctive nature of the new species. The traits of Indian species remain distinct from one another, except for the pileate basidiome with the mono-dimitic hyphal system, cystidioles and broadly ellipsoid basidiospores. Descriptions, illustrations, PHI test results and a phylogenetic tree to show the position of the new species are provided. In addition, an identification key to Tropicoporus in Asia and an African species is given. [ABSTRACT FROM AUTHOR]

New distributional data are given for four species. [ABSTRACT FROM AUTHOR]

Prior to this study, no species of Pseudophanias Raffray had been reported from Nanling, a vast biodiversity conservation area that spans five provinces in southern China. In this paper, three new species of the genus are described: Pseudophanias furcilobus sp. nov. (Guizhou, Guangxi), P. leigong sp. nov. (Guizhou), and P. mulun sp. nov. (Guangxi), suggesting that additional study on the diversity of this group in the area is required. These species are characterized, keyed, and compared to similar congeners, supplemented with illustrations of the habitus and other morphological characters. [ABSTRACT FROM AUTHOR]

Lumbrineriopsis dulcis sp. nov. is morphologically described from the continental shelf and slope of Espírito Santo and the Campos Basin of Rio de Janeiro state, southeastern Brazil, at depths between 14 and 400 m. Lumbrineriopsis mucronata is the only species of the genus recorded until now in Brazil. The new species differs from other congeneric species in its jaw-apparatus morphology with unfused mandibles and a fixed number of simple limbate chaetae and simple, bidentate, hooded hooks in each parapodium. This paper aims to fill the gap in knowledge on the family Lumbrineridae, which has not been studied in Brazil for the last 25 years and provides the first record of the genus from Espírito Santo and Rio de Janeiro states. This record is significant given the damage to the marine ecosystem of the Espírito Santo region due to the 2015 rupture of the Samarco mining company dam, the largest environmental disaster in Brazil's history. In addition, this region has important environmental conservation units such as Costa das Algas Environmental Protection Area, Santa Cruz Wildlife Refuge, and Comboios Biological Reserve. All these preserved areas are of paramount importance for the protection of marine biological diversity. [ABSTRACT FROM AUTHOR]

Background: During citizen-science expeditions to the Ulu Temburong National Park, Brunei, several individuals were collected of a semi-slug species of the genus Microparmarion that, based on morphology and in-the-field DNA-barcoding, was found to be an undescribed species. New information: In this paper, we describe Microparmarion sallehi Wu, Ezzwan & Hamdani, n. sp., after field centre supervisor Md Salleh Abdullah Bat. We provide details on the external and internal reproductive morphology, the shell and the ecology of the type locality, as well as a diagnosis comparing it with related species. DNA barcodes were generated for five individuals and used for a phylogenetic reconstruction. Microparmarion sallehi sp. n. and M. exquadratus Schilthuizen et al., 2019 so far are the only Bornean species of the genus that live in lowland forest; other species are found in montane forests.

Eight cobweb spider species building a detritus-based, bell-shaped retreat from China are reported in the current paper, including five new Campanicola species and three known species: Campanicola anguilliformis Li & Liu, sp. nov., Campanicola falciformis Li & Liu, sp. nov., Campanicola heteroidea Li & Liu, sp. nov., Campanicola tauricornis Li & Liu, sp. nov., Campanicola volubilis Li & Liu, sp. nov., Campanicola campanulata (Chen, 1993), Campanicola ferrumequina (Bösenberg & Strand, 1906), and Parasteatoda ducta (Zhu, 1998). Among them, the male of Parasteatoda ducta (Zhu, 1998) is described for the first time. We provide photographs of all species and descriptions for new species in the current paper. The type of bellshaped retreat is rare in theridiid, and found only in four related genera. A natural next step upon completing this taxonomic study would be to analyse and understand the evolution of the retreat and related traits. [ABSTRACT FROM AUTHOR]

Being nocturnal, hiding in prickly bushes and shrubs during the day, Eupholidoptera species in Crete and its neighbouring islands are easily overlooked, and until now our knowledge about their distribution was based on some thirty sightings across 11 species. In this paper results are presented of a study of Eupholidoptera specimens collected between 1987 and 2020 by hand-catches and pitfall and fermenting traps on the Greek islands of Crete, Gavdos, Gavdopoula, and Andikithira. Diagnostic features of all known species are presented and illustrated with stacked images. An updated key to all species is provided. Eupholidoptera francisae Tilmans & Odé, sp. nov. from Andikithira and southwestern Crete and Eupholidoptera marietheresae Willemse & Kotitsa, sp. nov. from Mt. Dikti are described. Female E. cretica, E. gemellata, and E. mariannae are described, and the female of E. astyla is redescribed. Bioacoustics for E. francisae Tilmans & Odé, sp. nov., E. giuliae, and E. jacquelinae are presented for the first time. Eupholidoptera smyrnensis is reported for the first time from Crete. A substantial amount of new distribution data for Eupholidoptera species on Crete is presented. The current distribution pattern and first analyses of phylogeny based on molecular data of Eupholidoptera species on Crete are discussed in relation to paleogeographical events.

The spider genus Episinus Walckenaer, 1809 currently contains 66 species worldwide, mostly in warm temperate to tropical areas. This paper describes two new Chinese Episinus species: E. ornithorrhynchus sp. nov. (♂♀) and E. papilionaceous sp. nov. (♀). We add these two new and one known Episinus species to the phylogenetic data matrix of Liu et al. 2016 and reanalyze the data. The new phylogeny recovers the monophyly of Episinus and supports its division into two groups, a finding also supported by morphology. [ABSTRACT FROM AUTHOR]

There is insufficient information to identify most species of the myrmecophilous rove beetle genus Homoeusa. In this paper, after examining the type material, Homoeusa rufescens (Sharp, 1874) is redescribed in detail and its new allied species Homoeusa ovata sp. nov. is described. We also observed the behavior of these two species in the field; the behavior was similar to that reported for H. acuminata (Märkel, 1842). A checklist of Homoeusa from the Palearctic and Nearctic is also provided. [ABSTRACT FROM AUTHOR]

The number of described species of the genus Terebellides Sars, 1835 (Annelida, Trichobranchidae) has greatly increased in the last years, particularly in the North East Atlantic. In this context, this paper deals with several putative species recently delineated by molecular means within a well delimited clade of Terebellides. Species are characterised here by a combination of morphological characters, and a complementary nucleotide diagnostic approach. Three species were identified as the nominal species T. stroemii Sars, 1835, T. bigeniculatus Parapar, Moreira & Helgason, 2011 and T. europaea Lavesque et al., 2019. Five species are described as new: T. bakkeni sp. nov., T. kongsrudi sp. nov., T. norvegica sp. nov., T. ronningae sp. nov. and T. scotica sp. nov. The distinctive morphological characters refer to the branchial shape, absence or presence of papillae on lamellae of anterior margin of branchial dorsal lobes, absence or presence of ciliated papillae dorsal to thoracic notopodia, geniculate chaetae in one or two chaetigers, and the morphology of thoracic and abdominal uncini teeth. Furthermore, the description of T. bigeniculatus is revised and complemented after examination of type specimens. An updated identification key to all species of the genus in NE Atlantic and a proposal of a classification of different types of abdominal uncini to be used in taxonomy are also included.
