The millipede family Haplodesmidae is reported from Colombia for the first time, represented by Inodesmus mesibovi sp. nov. and Inodesmus miconiae sp. nov. Their presence in primary and secondary oak forests suggests their native origin in Colombia. This discovery represents the first record of the genus Inodesmus Cook, 1896 in South America, with potential implications of further records of the genus and family from the continent. We also present the first record of teratologies in haplodesmid millipedes.

Five new species of Neurostigma collected in the Brazilian Amazon Rainforest are described and illustrated: Neurostigma alfonsoi sp. nov., N. patriciae sp. nov., N. angelicum sp. nov., N. spinosum sp. nov. and N. willkeniae sp. nov. The first record of Neurostigma for the Brazilian state of Rondônia is included, along with an unpdated distribution map of male specimens of Neurostigma. An updated identification key of males of the genus is provided. Now, the number of species of Neurostigma recorded for Brazil has increased to 12, with two of them also occurring in Colombia. With this study, we significantly contributed to the knowledge of the diversity of the genus, which increased to 19 species.

We present an updated global checklist of extant non-marine Ostracoda, covering taxonomic changes in the published literature up to 31st December 2023. The checklist is subjective, as apart from published taxonomic changes, also some additional alterations are proposed, including ten candonid tribes which are upgraded to subfamilies, six new combinations, one new name, five synonymies and one new taxonomic placement. The checklist presently includes 2420 accepted species in 295 genera, as well as 84 uncertain species that are too poorly described to be recognisable. We also provide the totals of species numbers for each taxonomic rank, from genera up to order, and numbers of species and endemic species in each of the world’s major zoogeographical regions.

All species of Umboniinae known to occur in New Caledonia are discussed (19 species, 8 new, belonging to 10 genera, 2 new) and a key to genera is provided. An additional new species is described from the Bismarck Sea. Nine species are perhaps endemic to New Caledonia. The diversity of the fauna is comparable to that of Japan and Australia, both regions of much greater extent and spanning a much broader latitudinal range. Ethalia lampra (Watson, 1880), previously known only from the original HMS Challenger material from Fiji, has been rediscovered in New Caledonia. Re-examination of the type material of Monilea apicina Gould, 1861 has led to a re-interpretation of the application of this name. Type specimens of a number of additional umboniine species examined for comparison are illustrated. Two new genera are proposed: Kanakina gen. nov. and Tylorhaphe gen. nov. Nine new species are described: Ethalia anomphala sp. nov., Ethminolia hickmanae sp. nov., Sericominolia porcata sp. nov., S. safrocincta sp. nov., Talopena maestratii sp. nov., Tylorhaphe alisae gen. et sp. nov., T. fritillaria gen. et sp. nov., T. luteopicta gen. et sp. nov. and T. wallacei gen. et sp. nov. Revised status: Talopena Iredale, 1918 is recognised as a full genus rather than a subgenus or synonym of Monilea Swainson, 1840. Minolia agapeta Melvill & Standen, 1896 is considered a distinct species, no longer to be regarded as a junior synonym of Monilea apicina Gould, 1861. Trochus (Monilea) lifuanus Fischer, 1878 is considered a distinct species, no longer to be regarded as a junior synonym of Monilea vernicosa Gould, 1861. New combinations: Monilea incerta Iredale, 1912 is reassigned to Talopena Iredale, 1918; Monilea apicina Gould, 1861, Monilea menkei A. Adams, 1855, Monilea philippii A. Adams, 1855, Pseudominolia tramieri Poppe, Tagaro & Dekker, 2006, Trochus belcheri Philippi, 1850, Trochus calyculus W. Wood, 1828, and Trochus (Monilea) masoni G. Nevill & H. Nevill, 1874 are all referred to Talopena Iredale, 1918. Minolia glaphyrella Melvill & Standen, 1895 is transferred to Kanakina gen. nov. Type localities: Nouméa, New Caledonia is designated as the type locality for Trochus nucleus Philippi 1850; the type locality ‘Port Jackson’ originally given for Monilea apicina Gould, 1861 is considered erroneous and is emended to Lansdowne Bank. New records for New Caledonian marine ecoregion: Ethalia lampra (Watson, 1880), Talopena apicina (Gould, 1861) and ‘Talopena’ tramieri (Poppe, Tagaro & Dekker, 2006).

This study aims to evaluate the taxonomic composition of the deep-sea triphorids from Guadeloupe obtained by the Karubenthos 2 expedition, which comprised 159 marine sampling events. The Karubenthos 2 sampled 14 deep-sea species of Triphoridae (i.e., species typically found below 200 m), which increases the number of deep-sea triphorids from Guadeloupe to 15. Three new species are described (Strobiligera picta sp. nov., S. variabilis sp. nov., S. cupella sp. nov.), six species were previously known only from the northern Caribbean or adjacent areas, one species (S. cf. delicata Fernandes & Pimenta, 2014) was previously known from SE Brazil, another species (S. dinea (Dall, 1927)) is widespread in the West Atlantic and only “Inella” longissima (Dall, 1881) was already recorded from Guadeloupe; two other morphs (Strobiligera sp. A, Strobiligera sp. B) remain without specific determination, requiring additional material. I formalize Norephora Gründel, 1975 syn. nov. as a junior synonym of Subulophora Laseron, 1958, which is probably related to Inella Bayle, 1879, but Strobiligera Dall, 1924 is regarded as a recent and derived group, restricted to deep waters of the Atlantic Ocean. Other taxonomic novelties in this study are: Costatophora numerosa (Jousseaume, 1898) comb. nov.; Euthymella sculpta (Hinds, 1843) comb. nov.; Strobiligera carioca sp. nov. (described from SE Brazil); Strobiligera colon (Dall, 1881) comb. nov.

The New Zealand cave wētā genus Isoplectron was first described by Hutton (1896) and included two species, Isoplectron armatum and I. calcaratum. Two more species, I. cochleatum and I. aciculatum, were described by Karny in 1935 and in 1937, respectively. The species I. cochleatum was later moved to the genus Pharmacus Pictet & de Saussure, 1893. Here we clarify the status and appearance of all known species of Isoplectron, and of other closely related cave wētā. Based on morphology and mtDNA sequences we determine that the genera Petrotettix Richards, 1972 and Setascutum Richards, 1972, belong in Isoplectron, and are thus synonymised with the latter. We also infer that Isoplectron aciculatum Karny, 1937 does not hold species rank, and that it should be considered a subspecies of Isoplectron armatum instead. The male of Isoplectron pallidum (Richards, 1972) comb. nov. and the female of Isoplectron armatum aciculatum Karny, 1937 are described here for the first time. Using molecular data, we also establish that two new species that are morphologically similar to Isoplectron are in fact more closely related to Pharmacus. These species are assigned to a new genus, Praecantrix gen. nov. We describe seven new species and two new subspecies of New Zealand rhaphidophorids belonging to the genera Isoplectron Hutton, 1896 and Praecantrix: Isoplectron bicolor sp. nov., I. maculatum sp. nov., I. virgatum sp. nov., I. ferratum sp. nov., I. parallelum sp. nov., Praecantrix silvatica silvatica gen., sp. et subsp. nov., P. silvatica lutea gen., sp. et subsp. nov. and P. saxicola gen. et sp. nov. Species demoted to subspecies rank: Isoplectron aciculatum Karny, 1937 becomes Isoplectron armatum aciculatum Karny, 1937. New combinations: Setascutum pallidum Richards, 1972 becomes Isoplectron pallidum (Richards, 1972) comb. nov.; Petrotettix serratus Richards, 1972 becomes Isoplectron serratum (Richards, 1972) comb. nov. New synonyms: Isoplectron calcaratum Hutton, 1896 = Isoplectron armatum Hutton, 1896 syn. nov.; Setascutum ohauensis Richards, 1972 = Isoplectron armatum Hutton, 1896 syn. nov.; Petrotettix spinosus Richards, 1972 = Isoplectron serratum (Richards, 1972) syn. nov.; Petrotettix cupolaensis Richards, 1972 = Isoplectron serratum (Richards, 1972) syn. nov.; Petrotettix nigripes Richards, 1972 = Isoplectron serratum (Richards, 1972) syn. nov.

A taxonomic revision of Stygnus Perty, 1833, in Colombia was conducted. The new species Stygnus apaporis sp. nov. is described from Lago Taraira, departments of Guaviare and Vaupés in the Colombian Amazonian region. The genus is recorded for the first time in eight Colombian departments: Amazonas, Caquetá, Casanare, Cundinamarca, Guaviare, Meta, Risaralda and Vaupés. New geographic records for S. gerstchi (Roewer, 1963) and comments about its type locality are offered. Two species are recorded for the first time in Colombia: Stygnus nogueirai Pinto-da-Rocha & Tourinho, 2012 (departments of Guaviare and Vaupés) and S. simonis Sørensen, 1932 (department of Amazonas). Some new geographic records of the genus in the Amazon region are presented, and it is recorded for the first time in Ceará state (Brazil) and Madre de Dios department (Peru), with the presence of two unidentified species. Updated distributional maps of the genus in Colombia and South America are offered. Finally, in taxonomic studies of Gonyleptoidea, six longitudinal rows of tubercles have been described on the legs. Here, these rows are identified for a species of the genus Stygnus and an additional row is detected and named.

Although the ant genus Temnothorax is broadly distributed, extremely diverse, and contains multitudes of undescribed species, discovering new Temnothorax species in the eastern United States is rare due to the high concentration of taxonomic effort on this region. Here, we recognize and describe a new species that has consistently been misidentified in museum collections as Temnothorax ambiguus, a common inhabitant of acorn shells and leaf litter. Unlike T. ambiguus, T. caryaluteus sp. nov. nests primarily in arboreal microhabitats, especially within dead branches on live Carya and Quercus trees. We compare the morphology of T. caryaluteus sp. nov. against the congeners with similar appearance T. ambiguus and T. curvispinosus, and delineate diagnostic characters for T. caryaluteus sp. nov. Moreover, we provide an updated key to the Temnothorax species of the eastern United States.

Kermadec Islands is a remote subtropical island arc in the Southwest Pacific Ocean located 800–1000 km northeast of New Zealand’s North Island. Until now, no data was available on the nematode fauna living in the seafloor environments surrounding these islands. A single sample of subtidal coarse sediments from the Raoul Island coast yielded four new ceramonematid species: Ceramonema taikoraha sp. nov., C. taiora sp. nov., Metadasynemoides taihua sp. nov. and Pselionema huakita sp. nov. This new discovery is the first addition to the family since 2008 and brings the total number of valid ceramonematid species globally to 67 species. Dichotomous identification keys are provided for valid species of Ceramonema, Metadasynemoides and Pselionema. The desmodorid species Acanthopharynx dormitata and Desmodora bilacinia, were also recorded from Raoul Island some 1350 km away from their type locality in Wellington Harbour (New Zealand’s North Island). These species may have a relatively widespread distribution but testing this hypothesis will require further morphological comparisons and analyses of molecular sequence data to confirm the status of the Kermadec specimens.
