Background: The Family Mesoveliidae, also known as the water treaders, are predaceous semi-aquatic bugs with approximately 50 known species worldwide. In the Korean Peninsula, only two species were known prior to this study: Mesoveliavittigera Horváth, 1895 and M.egorovi Kanyukova, 1981.

New information: A total of four species in two genera are recognised from Korea, including new distributional records of Mesoveliathermalis Horváth, 1915 and Speoveliamaritima Esaki, 1929. The record of M.egorovi Kanyukova, 1981 from Mt. Palgongsan, South Korea is doubtful. An identification key is provided to aid identification of the Korean species.

Background: The family Proalidae Harring & Myers, 1924, includes four genera and 53 species, distributed across all eight biogeographic realms and inhabiting various environments, including freshwater, saltwater and terrestrial environments. The genus Proales, the largest within Proalidae, encompasses 41 species characterised by diverse morphological traits. In Korea, the presence of Proalidae has been documented with five known species: Bryceellaperpusilla Wilts, Martínez Arbizu & Ahlrichs, 2010, B.stylata (Milne, 1886), B.tenella (Bryce, 1897), Proalesfallaciosa Wulfert, 1937 and Proalinopsiscaudatus (Collins, 1872).

New information: A new species, Proalesamplus sp. nov., is the 42^nd species within the genus Proales. This species exhibits unique morphological characteristics in the trophi, particularly in the epipharynx, which are distinctive enough to prevent misidentification with other Proales species. The habitus of the new species bears some resemblance to P.phaeopis Myers, 1933, sharing features, such as an elongated and fusiform body, two eyespots, a single foot pseudosegment, two short toes and the absence of a dorsal papilla between the toes. However, the epipharynx of the two species is markedly different. The unique epipharynx characteristic of this new species is unparalleled within the genus Proales.

Background: Buforubroventromaculatus Orlov, Ananjeva, Ermakov, Lukonina, Ninh & Nguyen, 2024 is a species recently described from Vietnam. Currently, this species is known from central and northern Vietnam and it uncertain whether this species is distributed in China. In addition, the original description of this species is very brief.

New information: Based on nine specimens collected from Yunnan Province and Guangxi Autonomous Region, China, we provide the first confirmed record of Buforubroventromaculatus from China. The morphological characteristics of the specimens from China mostly agree with the original description of B.rubroventromaculatus and, phylogenetically, the specimens from China clustered with the type series of B.rubroventromaculatus from Vietnam. We also provide a supplementary description of this species, based on the specimens we collected.

Background: Mexican terrestrial malacofauna is highly diverse, but poorly studied. The genus Humboldtiana includes near to 60 species, most with insular distributions on single mountains from South Texas (USA) to entral Mexico.

New information: Humboldtianadugesi sp. nov. is described from the state of Guanajuato, Mexico. This new species represents the first one described for the state and is diagnosed by the following combination of characters that allow distinguishing for other species included in the genus, a protoconch with growth lines and granulated microsculpture, a globose penis that bears a stout verge that covers half of the penis cavity and a long flagellum that is four times longer than the combined length of the penis and epiphallus.

Background: Phylum Phoronida currently contains two genera, Phoronis Wright, 1856 and Phoronopsis Gilchrist, 1907, with approximately thirteen speices. Phoronida is distributed worldwide, ranging from northern Europe to southern New Zealand and also from intertidal to 400 m depths. From Japanese waters, four species of Phoronis have been reported, viz. Phoronisijimai Oka, 1897, Phoronisaustralis Haswell, 1883, Phoronispsammophila Cori, 1889 and Phoronisemigi Hirose et al., 2014.

New information: We describe the morphology of Phoronopsiscalifornica Hilton, 1930, based on five specimens collected at a sandy-mud habitat in Nago Bay and Oura Bay, Okinawa, Japan. We examined the internal anatomy by serial paraffin sections. We also examined the genetic distance of Japanese specimens from the other phoronid sequences in GenBank. This is the first record of Phoronopsis from Japanese waters and the fifth species record of phoronids in addition to the previously recorded four species of Phoronis.

Background: The genus Anomalohalacarus Newell, 1949, which is known to occur exclusively inhabiting sand, has not been previously reported from Korea. During a recent survey of the meiofauna from several intertidal sandy beaches in South Korea, we found both sexes of two psammobiont halacarids, Anomalohalacarusangustus sp. nov. and A.biformis Abé, 1996.

New information: Both species are similar to each other in sharing an undivided posterior dorsal plate, three and two setae on the anterior and posterior epimeral plates, respectively, three bipectinate setae on tibia IV, and four ventral setae on tarsus I. However, A.angustus sp. nov. is distinguished from A.biformis by the absence of areolae posteriorly on the anterior dorsal plate, a much more slender posterior dorsal plate, a pair of subgenital setae on the genital foramen in females, and seven branched perigenital setae on the genitoanal plate in males. The feature of branched perigenital setae in males is reported for the first time in the genus Anomalohalacarus. The Korean specimens of A.biformis agree well with the original description from Japan, except for the number of ventral bipectinate setae on tibia II. This study presents (re)descriptions of both species with detailed illustrations and provides a dichotomous key to Anomalohalacarus species, including the new species, based on morphological characters. The genus Anomalohalacarus is reported for the first time in South Korea.

Background: The Atlantic Forest is one of the most diverse and threatened phytogeographical domains in the world. Despite that, it includes regions with poor floristic knowledge, even in protected areas. Although the importance of protected areas in conserving the Atlantic Forest hotspot is undisputed, it is necessary to recognise the floristic richness of these areas to propose effective conservation actions. In this sense, online databases have proved to be a promising tool for compiling species lists with relevant biodiversity information. This study is based on the list of vascular plants of the "Parque Estadual da Pedra Selada", published in the "Catálogo de Plantas das Unidades de Conservação do Brasil". It summarises the species richness, endemism and conservation status of this protected area.

New information: The published list of vascular plants was based on data obtained from herbarium collections available in online databases. A total of 303 species have been recorded for the "Parque Estadual da Pedra Selada," of which 297 are native to Brazil, 78 are endemic to the Brazilian Atlantic Forest, and seven are endemic to the State of Rio de Janeiro. More than 60% of the species are woody, and more than 40% are trees. Eight threatened species (Endangered - EN and Vulnerable - VU), of which five are endemic to the State of Rio de Janeiro, are housed in this protected area. One species was classified as Data Deficient (DD). Our results increase the knowledge of the Atlantic Forest flora in the State of Rio de Janeiro and support effective conservation planning for this protected area.

Background: The "Serra da Concórdia" is part of the Atlantic Forest phytogeographical domain in the Brazilian state of Rio de Janeiro and it has a predominant phytophysiognomy of Semideciduous Seasonal Forest. This region underwent intense habitat loss and fragmentation during the 19^th century, due to coffee plantations and later pastures. With the decline of these activities, the areas were abandoned, triggering secondary succession. In 2002, the "Parque Estadual da Serra da Concórdia" was established in this region to preserve the remaining forest fragments. The updated list of vascular plants recorded in this protected area, published in the "Catálogo de Plantas das Unidades de Conservação do Brasil", is presented here, along with information on richness, endemism, and conservation status.

New information: The "Parque Estadual da Serra da Concórdia" houses 231 vascular plant species, of which 90% are angiosperms, 10% ferns and lycophytes, and 27% endemic to the Atlantic Forest. Ten species are threatened with extinction, three are categorized as Endangered, and seven as Vulnerable. Although there have been expeditions in the "Parque Estadual da Serra da Concórdia", they have been limited, resulting in a low number of records and the species richness for a protected area. This is notable considering the 2,130 Brazilian native vascular plant species recorded in the semideciduous seasonal forest of Rio de Janeiro. Our data indicates that floristic inventories of Brazilian protected areas could help highlight gaps in flora knowledge and support the proposal of effective conservation actions.

Background: The genus Phyllothelys Wood-Mason, 1876 (Mantodea, Hymenopodidae) includes 22 species, with China being a major diversity hotspot, hosting 15 species in four groups.

New information: A new species of this genus from Malipo, Yunnan, China, is described herein, namely Phyllothelysqingjinum sp. nov. A comprehensive taxonomic description, including geometric morphometric analysis, genetic distance and molecular phylogenetic analysis, were employed to illustrate its distinctiveness. This discovery fills a significant distribution gap for the P.werneri species group in southern Yunnan and emphasises the need for further exploration in this region.

Background: According to the Species Catalogue of China, Tibet, China, has more than 1,000 species of bryophytes, showing its remarkably high biodiversity. Amongst them, the Polytrichaceae is one of the largest family, with six genera and 25 species, one subspecies and two varieties reported previously.

New information: Based on a field survey and specimen identification, the following species have been newly recorded in the bryoflora of Tibet, namely Oligotrichumobtusatum Broth., Pogonatumcontortum (Menzies ex Brid.) Lesq. and Polytrichumsphaerothecium (Besch.) Müll. Hal.
