Sampling of remote inland aquatic habitats in South Africa has constantly been yielding novel endemic freshwater crab species (Potamonautes MacLeay,1838). During the present study, we report on the discovery and description of two new freshwater crab species (Potamonautes baziya sp. nov., and P. mariepskoppie sp. nov.) from Afrotemperate forested mountain regions in the Eastern Cape and Mpumalanga provinces of South Africa, respectively. Phylogenetic evidence derived from DNA sequence data of three partial mitochondrial loci (12S rRNA, 16S rRNA and cytochrome oxidase subunit one, COI) corroborates the evolutionary distinction of the two novel species. In addition, morphological and ecological data for the two new species further delineate their evolutionary distinction from congeneric sister species. A comparison of the taxonomically important gonopods 1 and 2 and carapace features among the sister species and other known freshwater crabs of South Africa was further used to provide evidence for the distinction of the two novel species. The discovery of two new species suggest that remote mountainous areas or unsampled regions in South Africa likely harbor several novel species, reiterating a call to document aquatic inland biodiversity in forested and mountainous regions of the country.

Three subterranean leptodirine leiodid taxa, viz., Bozidaria Ćurčić & Pavićević gen. nov., Bozidaria serbooccidentalis Ćurčić & Pavićević gen. et sp. nov. and Proleonhardella (Proleonhardella) tarensis Ćurčić & Pavićević sp. nov., are described and diagnosed. Bozidaria Ćurčić & Pavićević gen. nov. belongs to the phyletic series of “Leonhardella”. The new beetle taxa differ from their closest relatives in numerous morphological characters. They most likely belong to phyletic lineages of Pliocene age. The new leiodid taxa are endemic to the Dinaric mountain chain of western Serbia. Keys to the leptodirine leiodid genera of the phyletic series of “Leonhardella” and to the taxa of the genus Proleonhardella Jeannel, 1910 are included.

The unique Neotropical species of the alderfly genus Protosialis van der Weele, 1909, P. bifasciata (Hagen, 1861), is herein transferred to the newly described genus Caribesialis gen. nov. This new taxon is proposed to be sister to the clade Protosialis + Sialis Latreille, 1802, after a phylogenetic analysis that included male genital characters scored on a previous morphological matrix of the family. Also, Ilyobius nigrocephalus sp. nov., a remarkable new species from Ecuador, is described and its phylogenetic position is discussed. Furthermore, Ilyobius bimaculatus (Banks, 1920) from Bolivia, known solely from the female holotype, is redescribed. Based on the present study, the Neotropical fauna of Sialidae is proposed to be constituted by two genera, one insular (Cuba) and one continental (Mexico to Chile and Argentina).

Samples collected in Central Asia, Kyrgyzstan, have revealed a hitherto unknown diversity of Campodeidae (Diplura) in soil and cave habitats, including a new genus and species, Kyrgyzstancampa sanare Sendra & Ferreira gen. et sp. nov., Turkmenocampa edaphica Sendra & Sánchez-García sp. nov. and a previously recognized soil-dwelling species, Campodea (Dicampa) catalana Denis, 1930. Kyrgyzstancampa sanare Sendra & Ferreira gen. et sp. nov. was collected in the deep zone of an interesting geological and cultural cave, Ak-Turpak Cave, located near the western margin of Kadamjay District, Batken Province. This genus belongs to the subfamily Campodeinae, sharing the morphology of the pretarsus with Eutrichocampa and other related genera, but differing from them in the shape of the claws and the laminar lateral processes, in addition to its unique cupuliform organ and the macrosetal pattern on the thorax and abdomen. Turkmenocampa edaphica Sendra & Sánchez-García sp. nov. was found in humid edaphic habitats, under stones or near roots, and is morphologically and geographically very similar to the cave-dwelling species Turkmenicampa mirabilis Sendra & Stoev, 2017, which occurs in an isolated cave in the nearby country of Turkmenistan.

In this study, the thallus-forming Laboulbeniomycetes (Herpomycetales and Laboulbeniales) from Denmark are presented as an illustrated monograph. Sixteen species and one genus are newly described based on morphology and ecology (host association). The new genus is named Tanmaurkiella Santam. gen. nov. and includes two species: T. pselaphi Santam. gen. et sp. nov. (type species) and T. huggertii Santam. gen. et sp. nov., both on Pselaphus heisei Herbst, 1792 (Col. Staphylinidae Pselaphinae). The other 14 new species are Amorphomyces ventricosus Santam. sp. nov. on Myrmecocephalus concinnus (Erichson, 1839) (Col. Staphylinidae Aleocharinae), Cantharomyces papillatus Santam. sp. nov. on Bledius terebrans (Schiødte, 1866) (Col. Staphylinidae Oxytelinae), Cryptandromyces cryptophagi Santam. sp. nov. on Cryptophagus distinguendus Sturm, 1845 (Col. Cryptophagidae), Cryptandromyces danicus Santam. sp. nov. on Euconnus wetterhallii (Gyllenhal, 1813) (Col. Staphylinidae Scydmaeninae), Dimeromyces oculatus Santam. sp. nov. on Longitarsus luridus (Scopoli, 1763) (Col. Chrysomelidae), Euphoriomyces enghoffii Santam. sp. nov. on Leiodes rugosa Stephens, 1829 (Col. Leiodidae), Euphoriomyces smicri Santam. sp. nov. on Smicrus filicornis (Fairmaire & Laboulbène, 1855) (Col. Ptiliidae), Laboulbenia inexpectata Santam. sp. nov. on Acupalpus exiguus Dejean, 1829 (Col. Carabidae), Laboulbenia pygidicola Santam. sp. nov. on Syntomus truncatellus (Linnaeus, 1761) (Col. Carabidae), Monoicomyces brachiatus Santam. sp. nov. on Atheta sodalis (Erichson, 1837) and Ocyusa picina (Aubé, 1850) (Col. Staphylinidae Aleocharinae), Monoicomyces crassicaulis Santam. sp. nov. on Oxypoda elongatula Aubé, 1850 (Col. Staphylinidae Aleocharinae), Monoicomyces reboleirae Santam. sp. nov. on Gnypeta carbonaria (Mannerheim, 1830) (Col. Staphylinidae Aleocharinae), Monoicomyces validus Santam. sp. nov. on Atheta vestita (Gravenhorst, 1806), Aleochara grisea Kraatz, 1856, and Geostiba circellaris (Gravenhorst, 1806) (Col. Staphylinidae Aleocharinae), and Stigmatomyces thoracochaetae Santam. sp. nov. on Thoracochaeta brachystoma (Stenhammer, 1855) (Diptera Sphaeroceridae). The total number of laboulbeniaceous species from Denmark rises from 29 to 195, which means that 166 are here reported as new country records. Among these, Kainomyces isomali Thaxt. deserves special mention as it is a new European record. The same applies to nine species which are reported here for the first time after their original description. For this study, an intensive sampling programme has been realized, with 429 Danish localities screened including around 1900 collections with fungi. Two new synonymies are established: Laboulbenia acupalpi Speg. (Spegazzini 1915a) syn. nov. for Laboulbenia stenolophi Speg. (Spegazzini 1914), and Monoicomyces oxytelis Huldén (Huldén 1983) syn. nov. for Monoicomyces invisibilis Thaxt. (Thaxter 1900). The new combination Peyritschiella oxyteli (Cépède & F.Picard) Santam. comb. nov. is proposed for Rheophila oxyteli Cépède & F.Picard including neotypification, and delimitation of Peyritschiella protea Thaxt. is incorporated. Lectotypes for Laboulbenia polyphaga Thaxt. and Symplectromyces vulgaris (Thaxt.) Thaxt. are designated. Nineteen species are illustrated here with photographs for the first time. Three species: Eumonoicomyces papuanus Thaxt., Peyritschiella protea, and Stigmatomyces euconni F.Picard, which were reported from Denmark in the literature should be removed from the Danish Funga. We have examined the following types of Thaxter from FH (Farlow Herbarium, Harvard University Herbaria): Asaphomyces cholevae Thaxt., Dimorphomyces myrmedoniae Thaxt., Eumonoicomyces papuanus, Laboulbenia polyphaga, Peyritschiella protea, Rhadinomyces pallidus Thaxt., and Symplectromyces vulgaris. Ceratomyces pyrenaeus Santam. is newly recorded from USA, and this is also a new record from the American continent. Description of the genus Cryptandromyces Thaxt. has been emended to incorporate the new species here described. Morphology of the antheridium in Eumonoicomyces papuanus is studied, and the status of the genus Eumonoicomyces Thaxt. vis-à-vis Monoicomyces Thaxt. is discussed. Identification keys are provided for genera and species. In support of the additional aim of this work to serve as a reference for the study of Laboulbeniomycetes fungi in Europe, we include maps and the Appendix 1 for comparison of the known species in the ten most diverse, better studied, European countries.

Neotropical species of the genus Idiops Perty, 1833 are reviewed, and four new species are described from Brazil: I. duocordibus Fonseca-Ferreira, Guadanucci & Brescovit sp. nov., I. guri Fonseca-Ferreira, Guadanucci & Brescovit sp. nov., I. mocambo Fonseca-Ferreira, Guadanucci & Brescovit sp. nov. and I. sertania Fonseca-Ferreira, Guadanucci & Brescovit sp. nov. The majority of species are redescribed based on the examination of the types and extensive material. Males of I. petiti (Guérin, 1838), I. rastratus (Pickard-Cambrige, 1889), I. rohdei Karsch, 1886 and I. nilopolensis Mello-Leitão, 1923, and females of I. fuscus Perty, 1833 and I. pirassununguensis Fukami & Lucas, 2005, hitherto unknown, are described for the first time. Idiops nilopolensis, considered a nomen dubium, is revalidated. Idiops fulvipes Simon, 1889 is synonymized with I. argus Simon, 1889, and I. santaremius (Pickard-Cambrige, 1896) is synonymized with I. petiti. Neotypes are designated for Idiops fuscus, I. nilopolensis and I. siolii (Bücherl, 1953). Idiops bonapartei Hasselt, 1888 is considered species inquirendae, since the type is an immature female. Finally, an updated distribution map of Neotropical species is included. The genus now has 24 species in the Neotropical region.

Nereis falsa de Quatrefages, 1866 has been regarded as a cosmopolitan species, and several species described from different localities have been regarded as junior synonyms of N. falsa. The present study is an attempt to resolve the taxonomic confusion in N. falsa, which seems to contain several distinct species due to previous inappropriate synonymy, widely distributed in the Atlantic and eastern Pacific Oceans. For this purpose, the authors first propose the resurrection of the synonymy of N. falsa with Hediste diversicolor that was concluded during the 19th century but disregarded later. After the fixation of the identity of N. falsa sensu stricto, the authors re-evaluate the proper taxonomic status of species which have previously been confused with N. falsa. Type, topotype and non-type specimens were examined; most species are redescribed, and others are reinstated. Nereis splendida Grube, 1840 is a valid Mediterranean species, and a neotype is proposed; it includes the Mediterranean populations of what is currently regarded as N. falsa. Consequently, N. falsa is transferred to Hediste Malmgren, 1867, and some taxonomic comments are added for the latter genus and a key to species is also included. Nereis callaona Grube & Kröyer in Grube, 1857, N. marginata Grube & Örsted in Grube, 1857 and N. riisei Grube & Örsted in Grube, 1857 are restricted to tropical American shores and are all redescribed. Nereis pelagica lunulata Ehlers, 1901, formerly regarded as a junior synonym of N. falsa by Fauvel (1941), is redescribed and elevated in rank to species level. Nereis lucipeta Ehlers, 1908, formerly regarded as a junior synonym of N. splendida by Ehlers (1913) and of N. falsa by Fauvel (1919), is reinstated. Nereis occidentalis Hartman, 1945 is also redescribed. Furthermore, N. ambigua Treadwell, 1937, formerly regarded as a junior synonym of N. riisei by Monro (1933), deserves to be reinstated. Western Africa specimens recorded as N. falsa are newly described as N. mezianei sp. nov.

Three species of Corethrella Coquillett, 1902 from the state of Amazonas, Brazil are described as new to science based on female adult specimens. Corethrella cabocla Feijó, Belchior, Marialva & Pessoa sp. nov. possesses four large setae on the frons between the ventromedial area of ommatidia, a wide clypeus with 1–4 setae, a wing with the apex of R2 basal to the apex of M2 and with a midlength band, and with the abdomen entirely dark brown. Corethrella ielemdei Feijó, Ramires, Lima & Pessoa sp. nov. possesses an elongated coronal suture, four large setae on the frons between the ventromedial area of ommatidia, a clypeus squarish with 42–43 setae, a wing with the apex of R2 basal to the apex of M1 and with a midlength band and dark scales on the basal and subbasal areas of the anterior margin, legs with dark scales, and with the abdomen entirely dark brown. Corethrella menini Feijó, Picelli, Ríos-Velásquez & Pessoa sp. nov. possesses wings with the apex of R2 basal to the apex of M2 and a midlength band, with darker basal scales along all veins, basal band dark scales on C, Sc, R, M, and Cu and the abdomen entirely dark brown. With the addition of the new species, the numbers of frog-biting midges described in the Amazon basin, Brazil and in Neotropical region are now 31, 49 and 80 species, respectively.

The myrmecophilous Paederinae rove beetle genus Megastilicus Casey, 1889 from North America is reviewed based on museum specimens. Prior to this study, the genus was monotypic with one species Megastilicus formicarius Casey, 1889 described. Here, we provide a redescription of the genus and the type species, designate a lectotype, and provide pictures of habitus and illustrations of the aedeagus and genital segments. Additionally, we describe a new species for the genus, Megastilicus iowaensis sp. nov., include an identification key to the two species and present the distribution map of both of them, including new state records. We discuss the assignment of the genus to the subtribe Stilicina based on morphological features.
