The hoverfly genus Eumerus Meigen, 1822 (Eristalinae: Merodontini) comprises 250+ described species, of which 36 are reported from the Iberian Peninsula. The high species diversity linked to the low degree of morphological differentiation between some species, which is even lower in females, leads to a high taxonomic complexity in this genus. The aim of this work is to confirm the morphological and molecular validity of an undescribed species of Eumerus, which is widespread in the Iberian Peninsula. The new species is described and compared with similar species. The genitalia of the new species are similar to those of Eumerus clavatus Becker, 1923 and Eumerus uncipes Rondani, 1850, but also share some features with Eumerus nudus Loew, 1848. The COI-5’ barcode is provided for the new taxon and analysed together with those of other named Eumerus sequences/species publicly available online. In the light of the morphology and barcoding data, the systematic position of the new species is discussed.
The genus Seticornuta Morley, 1913 currently comprises nine described species; here, nine new species are described: S. anchanchu sp. nov., S. carinata sp. nov., S. cuckoo sp. nov., S. curupira sp. nov., S. flava sp. nov., S. muqui sp. nov., S. nigroflava sp. nov., S. quilmes sp. nov., and S. rufa sp. nov. The genus is redescribed to encompass the features found in Neotropical species and distinctions between the species in the New World and Old World are presented. The genus is recorded for the first time for Argentina, Bolivia, Ecuador, Guatemala and Peru.
The pseudoscorpion (Arachnida: Pseudoscorpiones) fauna of mainland Ecuador, excluding the Galápagos Islands, is poorly known, with only 41 described species in 9 families. The family Syarinidae has a pantropical distribution and presently comprises ca 120 species in 17 valid genera that are found in leaf litter and subterranean habitats, mostly in tropical and subtropical climates. Four syarinid species have been recorded from Ecuador, including the Galápagos, in two widespread genera, Ideobisium and Ideoblothrus, but field collections suggest that these pseudoscorpions are common and abundant in all forest systems across the country. Here, we review field collections of syarinids from mainland Ecuador and describe five new species in these genera: Ideobisium kichwa sp. nov. (Napo Province, Colonso Chalupas Natural Reserve), I. sonqo sp. nov. (Napo Province, Colonso Chalupas Natural Reserve), I. susanae sp. nov. (Napo Province, Jatun Sacha Natural Reserve), Ideoblothrus nadineae sp. nov. (Napo Province, Colonso Chalupas Natural Reserve) and I. safinai sp. nov. (Pichincha Province, Otongachi Natural Reserve) based on morphology. These species seem to have narrow distributions and we therefore restrict the ranges of two species previously recorded from Ecuador (Ideobisium crassimanum Balzan, 1892 and Ideoblothrus costaricensis (Beier, 1931)) to their countries of origin, which is Costa Rica and Venezuela, respectively.
A new species of the genus Caucaseuma Strasser, 1970, Caucaseuma strasseri Antić sp. nov., is described from a cave in the Western Caucasus, representing the eighth species of the genus, and the fourth presumed troglobiontic Caucaseuma. An updated key to and a distribution map of all eight species of Caucaseuma is presented, including new records. In addition, the cave millipede fauna of the Caucasus is briefly discussed, with the inclusion of the most relevant references.
Two new species of the family Nemouridae of the genus Indonemoura Baumann, 1975, Indonemoura yingjiangensis Bai & Qian sp. nov. and Indonemoura longihamata Bai & Qian sp. nov. are described from Yunnan Province, southwest of China. The morphological characteristics of the two new species are compared to related taxa.
Chvalaea australis sp. nov. is described and illustrated, representing the first species of Chvalaea Papp & Földvári, 2002 from the Australasian Region. A discussion of the geographic distribution and the possible relationship among the species of the genus is provided.
The present study aims to resolve the taxonomic confusion involving several taxa within Mycetophagidae Leach, 1815, originating from the introduction of the genus Atritomus Reitter, 1877, and then by its subsequent controversial interpretation. A detailed overview of the taxonomic and nomenclatural history of the taxa previously linked to Atritomus is provided. The authors propose the introduction of Stereophilus Biscaccianti, Audisio & Esser gen. nov. for Atritomus filicornis Reitter, 1887, and the restoration of Entoxylon Ancey, 1869 at the genus rank, together with some rectifications regarding the authorship and the date of publication of both Entoxylon and its type species, E. abeillei Ancey, 1869. Moreover, the Ethiopian species Atritomus vicinus Grouvelle, 1908 is herein transferred to the genus Typhaeola Ganglbauer, 1899 based on the examination of the holotype. The following new combinations are proposed: Entoxylon baudii (Seidlitz, 1889) comb. nov. (from Esarcus Reiche, 1864), Entoxylon besucheti (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon franzi (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon inexpectatus (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon martini (Reitter, 1887) comb. nov. (from Esarcus), Stereophilus filicornis (Reitter, 1887) gen. et comb. nov. (from Atritomus), Typhaeola vicina (Grouvelle, 1908) comb. nov. (from Atritomus).
The western Indian Ocean genus Paracephaelis is revised. Sixteen species are endemic to Madagascar, 12 of which are new for science: P. aristata sp. nov., P. bardotiae sp. nov., P. capitulifera sp. nov., P. gautieri sp. nov., P. grandifructa sp. nov., P. longipedicellata sp. nov., P. orientalis sp. nov., P. pauciflora sp. nov., P. ranirisonii sp. nov., P. russata sp. nov., P. sambavensis sp. nov., and P. seyrigii sp. nov. Paracephaelis trichantha occurs on the east coast of continental Africa and on the islands of the Aldabra Group. One other species is newly described from the Comoros, P. comorensis sp. nov. Paracephaelis is characterized by sessile inflorescences, pubescent inflorescence and flower parts, ovules arranged at the periphery of the placenta, laterally flattened seeds with entire endosperm and a shallow elongate hilum, and pollen with supratectal elements. Of the Malagasy endemics, five species are assessed as Critically Endangered with P. sambavensis sp. nov. possibly Extinct in the Wild, three are Endangered, four are Vulnerable, one is Near Threatened, and three are Least Concern. Outside Madagascar, P. trichantha and P. comorensis sp. nov. are assessed as Vulnerable.

Contrary to what its name suggests, Nemesia arboricola is not strictly arboreal in habit. Here we compare female specimens of N. arboricola collected from arboreal and terrestrial nests. We furthermore describe the male of N. arboricola for the first time as well as two recently discovered species of Nemesia (N. maltensis sp. nov. and N. cominensis sp. nov.). Nemesia maltensis is described from both sexes, N. cominensis is described from the female and a juvenile male specimen. For N. cominensis we discuss the sexual dimorphism of juvenile male and female spiders. Field observations and laboratory observations show remarkable features of the Maltese Nemesia fauna that are unknown from Nemesia species found elsewhere. Particularly, the arboreal dwellings of N. arboricola and the absence of a trapdoor to close off the burrow entrance in N. maltensis appear to be exceptional. The composition of the Maltese Nemesia fauna, as located in the central Mediterranean, is finally discussed in relation to the different Nemesia species-complexes occurring in the eastern and western Mediterranean basin.
