Reports of cases of cryptic and pseudocryptic speciation have increased in the last decade among marine invertebrates thanks to the use of integrative taxonomy that combines all available data sources to correctly establish species boundaries, now routinely incorporated into classical taxonomical studies. This approach has enhanced our understanding of the real biodiversity of a given area, which has fundamental implications for conservation and management of marine ecosystems. Among polychaete annelids, considered one of the most ubiquitous and abundant groups in our oceans, there are numerous documented cases of cryptic and pseudocryptic speciation, mainly in those highly diverse families as Syllidae Grube, 1850. One of the most recent cases of species complex has been reported in Syllis prolifera Krohn, 1852 - traditionally considered a widespread, cosmopolitan species - and now recognised as a pseudocryptic complex in the western Mediterranean Sea. However, its broader distribution suggests that additional pseudocryptic lineages may exist in other regions of the Mediterranean basin. In this study, newly collected specimens from the Greek islands of Crete and Mykonos are combined with all previously published data on the S. prolifera complex, aiming to assess the existence of additional putative Mediterranean species. Combining morphological, biogeographical, and molecular data (COI, 16S rRNA, 18S rRNA, and 28S rRNA markers) the presence of at least three more novel lineages for the eastern Mediterranean Sea is revealed. However, unlike previous studies, no clear diagnostic morphological characters were found for each lineage, suggesting that the complex includes both pseudocryptic and cryptic potential new species. Our results further reinforce the view that species diversity within the family Syllidae remains underestimated and highlight the necessity of integrative studies to accurately assess marine invertebrate biodiversity.

A synopsis of the species of the genus Zaitzevia Champion, 1923 from Shaanxi Province (China) is provided. Five new species are described: Z. coronifer sp. nov., Z. disparilis sp. nov., Z. hybrida sp. nov., Z. pilosa sp. nov., and Z. robusta sp. nov. These five new species are not confined to Shaanxi but recorded also from other provinces: Z. coronifer (Hubei), Z. disparilis (Anhui, Gansu, Guizhou, Hunan), Z. hybrida (Gansu, Sichuan, Yunnan), Z. pilosa (Hubei, Hunan), and Z. robusta (Hubei, Sichuan). A key to the six Zaitzevia species currently known from Shaanxi, as well as photographs of the habitus and the aedeagi, are provided. The morphological delimitation of the genera Zaitzevia and Zaitzeviaria Nomura, 1959 is briefly discussed on the basis of the newly established Zaitzevia hybrida species group, which is wide-spread in the Himalaya and China and combines diagnostic characters of Zaitzevia as well as Zaitzeviaria. In addition, an updated checklist of the 21 species of Zaitzevia now recorded from China is presented. The genus Zaitzevia is recorded for the first time from Anhui, Gansu, and Guizhou. Zaitzevia fengtongzhaiensis Jiang & Chen, 2023 is recorded for the first time from Gansu and Yunnan. Based on particular morphological characters, the specimens recorded by Bian and Zhang (2022) from Shaanxi and Yunnan as Z. chenzhitengi are here regarded as a closely related, undescribed species.

Butterflies and moths (Lepidoptera) are one of the most commonly found insect groups in museum collections. Yet many specimens still lack digital data and few digitization workflows are available. Here we present a digitization workflow for natural history collections that can be widely applicable for any museum or dried pinned-specimen collection of Lepidoptera. Our workflow consists of pre-imaging preparation, usage of a copy stand for imaging pinned specimens and data labels, image processing, and transcription, the latter two which utilize Python scripts for optimization.

The present study aimed to provide a species list of amphibians from Iguaçu National Park, the largest forest fragment of inland Atlantic Forest, located in the westernmost region of Paraná state, recognized as a UNESCO Natural Heritage Site. The park's vegetation is predominantly composed of two types: Semideciduous Seasonal Forest (SSF) and Mixed Ombrophilous Forest (MOF). To compile the species list, primary data obtained through sampling adult anurans and tadpoles in 21 water bodies was used, complemented by search for historical records based on specimens deposited in scientific collections. 31 anuran species belonging to seven families were recorded, with the Hylidae being the richest, comprising 17 species. Two species, Boana curupi and Physalaemus carrizorum, represent the first records in the state of Paraná. The anuran species recorded in the Iguaçu National Park present nine reproductive modes, reflecting a diversity similar to that observed in other areas of Semideciduous Seasonal Forest. Twelve species were recorded exclusively in the SSF, eight species exclusively in MOF, and 11 species occurred in both vegetation types. The anuran assemblage of Iguaçu National Park is most similar to that Iguazú National Park in Argentina, with which it shares 24 species. Although the Iguaçu River is the only geographic barrier separating these two protected areas, the complementarity in amphibian species composition highlights the importance of conserving both parks for maintaining regional biodiversity.

A new monstrilloid copepod species, Cymbasoma stricturum sp. nov., is described and illustrated on the basis of adult females from the Pearl River estuary, northern South China Sea. The new species is closest to C. morii Sekiguchi, 1982, C. sinopense Üstün, Terbiyik & Suárez-Morales, 2014, and C. jinigudira Suárez-Morales & McKinnon, 2016, but it can be distinguished by a combination of characters including strongly protuberant, straight oral papilla; a cephalothorax that is distinctly constricted at the anterior two-fifths in both dorsal and lateral views; and two pairs of well-developed nipple-like processes on anterior dorsal surface, among other diagnostic traits. This is the ninth nominal species known in the Cymbasoma longispinosum species-group. We provide an updated dichotomous key for females and a revised worldwide distribution map of the species-group.

The spider genus Pholcus Walckenaer, 1805 exhibits high diversity in eastern Sichuan, China, and 19 species have been recorded in this area so far. In this study, two additional new species of Pholcus from north of the Sichuan Basin are described, Pholcus jiuzhai Yan, Li & Yao, sp. nov. (♂♀) from the crypticolens group and Pholcus pingwu Yan, Li & Yao, sp. nov. (♂♀) from the yichengicus group. In addition, an updated list of all Pholcus species from eastern Sichuan is provided.

In this paper, Mimogeniates margaridae Martínez (Scarabaeidae, Rutelinae, Geniatini) is synonymized with Leucothyreus noctivagus Ohaus (syn. nov.). Hence, the monotypic genus Mimogeniates Martínez is a new junior synonym of Leucothyreus MacLeay (syn. nov.). Leucothyreus noctivagus is redescribed and illustrated based on the type and additional material, including new distributional records in southern Brazil. As a result of our work, the tribe Geniatini now includes 12 genera.

Three species of Signiphoridae are recorded from the Xishuangbanna Rainforest (China, Yunnan). Chartocerus menglaensis sp. nov. is described as new to science. Chartocerus niger (Ashmead) and Signiphora flavella Girault are recorded from China for the first time. A key to all Chinese species of Signiphoridae is provided.

This study presents a thorough overview of the diversity of the Trichoptera fauna in Croatia, encompassing several key aspects. First, it offers a historical overview of Trichoptera research conducted within the country, tracing the development and major milestones of this field. Second, it provides a detailed analysis of the distribution and species diversity of caddisflies across Croatia's three geographical regions, the Continental, Alpine, and Mediterranean, as well as within two ecoregions (ER5 - Dinaric Western Balkan and ER11 - Pannonian Lowlands) and two major river basins (AS - Adriatic Sea basin and BS - Black Sea basin). This biogeographic assessment is based on comprehensive records of adult specimens and, in certain cases, on DNA barcoding data obtained from larval stages. Third, the study includes a thorough examination of species synonyms and a critical review of the existing literature. Finally, it delivers a faunistic and taxonomic review of selected species and subspecies. A total of 225 species belonging to 18 families and 74 genera have been identified. Two of these species are represented by two and three subspecies, respectively, bringing the total number of recorded Trichoptera taxa in Croatia to 228. The presence of 223 species was confirmed in the adult stage. Only two species were identified by DNA barcoding as larvae. In the Continental region 170 species were recorded, in the Alpine region 155, and in the Mediterranean part 131 species. The Black Sea basin contains 203, and the Adriatic basin 141 species. In the Pannonian Lowland region (Ecoregion 11) we determined 152 and in the Dinaric Western Balkan (Ecoregion 5) 197 species. The BOLD Systems database currently contains about 593 DNA barcoded Trichoptera specimens from Croatia comprising 176 species, identifying 211 BINs, covering 78% of Croatian Trichoptera fauna.
