The pteromalid parasitoid Lariophagus distinguendus (Foerster) belongs to the Hymenoptera, a megadiverse insect order with high cryptic diversity. It attacks stored product pest beetles in human storage facilities. Recently, it has been shown to consist of two separate species. To further study its cryptic diversity, strains were collected to compare their relatedness using barcoding and nuclear genes. Nuclear genes identified two clusters which agree with the known two species, whereas the barcode fragment determined an additional third Clade. Total reproductive isolation (RI) according to the biological species concept (BSC) was investigated in crossing experiments within and between clusters using representative strains. Sexual isolation exists between all studied pairs, increasing from slight to strong with genetic distance. Postzygotic barriers mostly affected hybrid males, pointing to Haldane's rule. Hybrid females were only affected by unidirectional Spiroplasma‐induced cytoplasmic incompatibility and behavioural sterility, each in one specific strain combination. RI was virtually absent between strains separated by up to 2.8% COI difference, but strong or complete in three pairs from one Clade each, separated by at least 7.2%. Apparently, each of these clusters represents one separate species according to the BSC, highlighting cryptic diversity in direct vicinity to humans. In addition, these results challenge the recent 'turbo‐taxonomy' practice of using 2% COI differences to delimitate species, especially within parasitic Hymenoptera. The gradual increase in number and strength of reproductive barriers between strains with increasing genetic distance also sheds light on the emergence of barriers during the speciation process in L. distinguendus.

The DNA of Trigonopterus specimens from the Sundaland region stored between ten and 32 years in museums could be used for next-generation sequencing. The availability of their cox1 sequence allowed the description of the following nine new species: Trigonopterus grimmi sp. nov., T. johorensis sp. nov., T. lambirensis sp. nov., T. linauensis sp. nov., T. microreticulatus Riedel, Trnka & Wahab sp. nov., T. mulensis sp. nov., T. sarawakensis sp. nov., T. siamensis sp. nov., and T. singaporensis sp. nov. The alternative original spelling of the name T. tounensis Narakusumo & Riedel is chosen to prevail over T. tounaensis Narakusumo & Riedel. The new species represent the first country records of Trigonopterus for Brunei, Singapore, and Thailand. Thus, the genus' known area of distribution in the Sundaland region is significantly extended. A key and a catalogue are provided to the Trigonopterus species from Borneo, W-Malaysia, Singapore, and Thailand. [ABSTRACT FROM AUTHOR]

This fills important areas of distribution and brings the number of Trigonopterus species recorded from Sulawesi to 132. [ABSTRACT FROM AUTHOR]

Based on recent fieldwork, the hyperdiverse weevil genus Trigonopterus Fauvel is recorded for the first time from the Indonesian Tanimbar Archipelago, halfway between Australia and Western New Guinea. All seven species discovered on Tanimbar are new to science, and described here: Trigonopterus atuf sp. nov., T. kumbang sp. nov., T. laratensis sp. nov., T. porg sp. nov., T. selaruensis sp. nov., T. tanimbarensis sp. nov., and T. triradiatus sp. nov. The new species are authored by the taxonomists-in-charge, Raden Pramesa Narakusumo and Alexander Riedel. This fauna appears discordant and established by relatively recent dispersal from New Guinea and other Moluccan islands. [ABSTRACT FROM AUTHOR]

The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia, the Moluccas, and the Sunda Islands. Only one species, Trigonopterus fulvicornis (Pascoe, 1885) was so far recorded from Sulawesi. Based on focused field-work the fauna from Sulawesi and nearby islands is here revised.

The descriptive biology of torrent mites (Parasitengona: Torrenticolidae: Torrenticola) of North America (north of Mexico) is investigated using integrative methods. Material examined includes approximately 2,300 specimens from nearly 500 localities across the United States and Canada, and a few collections in Mexico and Central America. Species hypotheses are derived from a phylogenetic analysis of the barcoding region of cytochrome c oxidase subunit 1 (COI) for 476 specimens and supported with morphology and biogeography. Relationships between species are examined with a combined analysis of COI and two expansion regions (D2-3) of the large ribosomal subunit (28S rDNA) for 57 specimens. All previously described species from the US and Canada are examined. Our results indicate the need to synonymize four species: T. mercedensis (Marshall, 1943) is a junior synonym of T. sierrensis (Marshall, 1943); T. rectiforma Habeeb, 1974 is a junior synonym of T. ellipsoidalis (Marshall, 1943); T. neoconnexa Habeeb, 1957 is a junior synonym of T. magnexa Habeeb, 1955; and T. esbelta Cramer, 1992 is a junior synonym of T. boettgeri KO Viets, 1977. We describe 66 new species and re-describe all previously described regional species. Our findings indicate that total diversity of Torrenticola in the United States and Canada comprises 90 species, 57 known from the east and 33 from the west. We organize these species into four species complexes that include 13 identification groups. An additional 13 species do not fit within an identification group. The southern Appalachians are suspected to contain the highest concentration of remaining undescribed diversity. A key is provided to all known species in the US and Canada. [ABSTRACT FROM AUTHOR]

The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia. Only one species, Trigonopterus amphoralis Marshall, 1925 was so far recorded West of Wallace's Line (Eastern Sumatra). Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised. We redescribe T. amphoralis Marshall and describe an additional 98 new species: T. acuminatus sp. n., T. aeneomicans sp. n., T. alaspurwensis sp. n., T. allopatricus sp. n., T. allotopus sp. n., T. angulicollis sp. n., T. argopurensis sp. n., T. arjunensis sp. n., T. asper sp. n., T. attenboroughi sp. n., T. baliensis sp. n., T. batukarensis sp. n., T. bawangensis sp. n., T. binodulus sp. n., T. bornensis sp. n., T. cahyoi sp. n., T. costipennis sp. n., T. cuprescens sp. n., T. cupreus sp. n., T. dacrycarpi sp. n., T. delapan sp. n., T. dentipes sp. n., T. diengensis sp. n., T. dimorphus sp. n., T. disruptus sp. n., T. dua sp. n., T. duabelas sp. n., T. echinatus sp. n., T. empat sp. n., T. enam sp. n., T. fissitarsis sp. n., T. florensis sp. n., T. foveatus sp. n., T. fulgidus sp. n., T. gedensis sp. n., T. halimunensis sp. n., T. honjensis sp. n., T. ijensis sp. n., T. javensis sp. n., T. kalimantanensis sp. n., T. kintamanensis sp. n., T. klatakanensis sp. n., T. lampungensis sp. n., T. latipes sp. n., T. lima sp. n., T. lombokensis sp. n., T. merubetirensis sp. n., T. mesehensis sp. n., T. micans sp. n., T. misellus sp. n., T. palawanensis sp. n., T. pangandaranensis sp. n., T. paraflorensis sp. n., T. pararugosus sp. n., T. parasumbawensis sp. n., T. pauxillus sp. n., T. payungensis sp. n., T. porcatus sp. n., T. pseudoflorensis sp. n., T. pseudosumbawensis sp. n., T. punctatoseriatus sp. n., T. ranakensis sp. n., T. relictus sp. n., T. rinjaniensis sp. n., T. roensis sp. n., T. rugosostriatus sp. n., T. rugosus sp. n., T. rutengensis sp. n., T. saltator sp. n., T. santubongensis sp. n., T. sasak sp. n., T. satu sp. n., T. schulzi sp. n., T. sebelas sp. n., T. sembilan sp. n., T. sepuluh sp. n., T. seriatus sp. n., T. serratifemur sp. n., T. setifer sp. n., T. silvestris sp. n., T. singkawangensis sp. n., T. singularis sp. n., T. sinuatus sp. n., T. squalidus sp. n., T. sumatrensis sp. n., T. sumbawensis sp. n., T. sundaicus sp. n., T. suturalis sp. n., T. syarbis sp. n., T. telagensis sp. n., T. tepalensis sp. n., T. tiga sp. n., T. trigonopterus sp. n., T. tujuh sp. n., T. ujungkulonensis sp. n., T. variolosus sp. n., T. vulcanicus sp. n., T. wallacei sp. n.. All new species are authored by the taxonomist-in-charge, Alexander Riedel. Most species belong to the litter fauna of primary wet evergreen forests. This habitat has become highly fragmented in the study area and many of its remnants harbor endemic species. Conservation measures should be intensified, especially in smaller and less famous sites to minimize the number of species threatened by extinction. [ABSTRACT FROM AUTHOR]

A species discovery and description pipeline to accelerate and improve taxonomy is outlined, relying on concise expert descriptions, combined with DNA sequencing, digital imaging, and automated wiki species page creation from the journal.

During the research cruises aboard the R/V Akademik M.A. Lavrentyev in 2016, 2018, and 2021 four nemertean species were collected from the bathyal zone of the Bering Sea: Cerebratulus mordukhovichi sp. nov., Lineidae sp. Bering G06, Nipponnemertes cf. rubella (Koryak slope, depths 420–662 m), and Oerstedia sp. (Piip Volcano, depth 783–984 m). These species, as well as deep-sea nemerteans collected in the Northwestern Pacific, the North Atlantic, Arctic, and Antarctic, were included in a phylogenetic analysis of Lineidae, Cratenemertidae, and Oerstediidae based on five gene markers (COI, 16S, 18S, 28S, and histone H3). It has been shown that deep-sea species of Lineidae are found in 8 phylogenetic lineages out of 12, with new Lineage Q comprised only of deep-sea species. Lineidae sp. Bering G06 belongs to Lineage G and is closely related to Lineidae sp. 3DS from the abyssal zone of the Sea of Okhotsk. Cerebratulus mordukhovichi sp. nov., found in the Bering Sea and off the Kuril Islands, belongs to Lineage J and the subclade including " Micrura " bathyalis , Cerebratulus herculeus , and Cerebratulus californiensis. Nipponnemertes cf. rubella , found at depths from 5 to 662 m in the Bering Sea, off the Kuril Islands, and California, belongs to clade A and is very close to N. pulchra (with COI p -distances within 3.8–4.3%). Oerstedia sp. is the deepest-dwelling of all known members of the genus Oerstedia , but it does not belong to any of the two clades (Oerstedia and Paroerstediella) of this genus. The subgenus Kurilonemertes Chernyshev, 1993 is upgraded to the genus level. The assumption on eurybathic distribution of any nemertean species should be supported by genetic methods. Pseudomicrura afzelii and Gononemertes parasita are confirmed to be eurybathic species found at depths from 15–70 m–886 m. • Deep-sea lineids are found in 8 lineages, with one lineage comprised only of deep-sea species. • All individuals identified as Oerstedia form a single highly supported clade. • The subgenus Kurilonemertes Chernyshev, 1993 is upgraded to the genus level.

Accurate diagnosis of the components of our food and a standard lexicon for clear communication is essential for regulating global food trade and identifying food frauds. Reliable identification of wild collected foods can be particularly difficult, especially when they originate in under-documented regions or belong to poorly known groups such as Fungi. Porcini, one of the most widely traded wild edible mushrooms in the world, are large and conspicuous and they are used as a food both on their own and in processed food products. China is a major exporter of porcini, most of it ending up in Europe. We used DNA-sequencing to identify three species of mushroom contained within a commercial packet of dried Chinese porcini purchased in London. Surprisingly, all three have never been formally described by science and required new scientific names. This demonstrates the ubiquity of unknown fungal diversity even in widely traded commercial food products from one of the most charismatic and least overlooked groups of mushrooms. Our rapid analysis and description makes it possible to reliably identify these species, allowing their harvest to be monitored and their presence tracked in the food chain.
