Keys and diagnoses of North European aphids (Hemiptera, Aphidoidea) associated with mosses, horsetails and ferns are given, based on fresh and freeze-dried material. Numerous externally visible and thus informative characters, that are absent in cleared, slide-mounted specimens, such as body shape colours, wax coating and pattern etc., are utilized. Most of the species are illustrated by photographs of live specimens and drawings. Root-feeding species living in the moss layer or otherwise often present in moss samples are also included, even if their hosts were spermatophytes. The combination of colour images and diagnoses, utilizing easily observed characters, allows the identification of a large number of species already in the field, and many more at home with the aid of a stereo microscope. Host plant relationships and association with ants are summarised, including new records. Brief accounts on aphid life cycles, freeze-drying preparation techniques, etc. are also given to support the use of the keys.

Morphological (shell) and molecular examination of a large suite of specimens of pleurotomariids from around New Caledonia and the Coral Sea reveals the existence of four species in the complex of Perotrochus caledonicus: Perotrochus deforgesi Métivier, 1990 and P. pseudogranulosus sp. nov. live allopatrically on the plateaus and guyots of the Coral Sea; Perotrochus caledonicus Bouchet & Métivier, 1982 and Perotrochus wareni sp. nov. live sympatrically - but essentially not syntopically - on the slopes of New Caledonia, Norfolk Ridge and the Loyalty Ridge. All species live in the 300–500 m interval, and together form a significant component of the mollusc fauna living on hard bottoms in the SW Pacific, with individual dredge hauls containing up to 25 specimens of Perotrochus.

Sharon gen. nov. is here described to include Asaphes? amoenus Philippi, 1861 comb. nov. from Chile. A redescription of the species is based on the female holotype and material from different geographic locations. Candèze (1891) placed Asaphes amoenus and Parasaphes elegans in the suprageneric group Asaphites. We discuss differences between Sharon gen. nov. and Hemicrepidius Germar, 1839, where Asaphes amoenus was later placed by Blackwelder (1944). Based on morphological characters, Sharon gen. nov. appears to be related to Parasaphes Candèze, 1881, Wynarka Calder, 1986, and Tasmanelater Calder, 1996, all from Australia, suggesting Gondwanan relationships.

Two new junior synonyms, Pseudomesitius Duchaussoy, 1916 syn. nov. and Triglenus Marshall, 1905 syn. nov., for the genus Bradepyris Kieffer, 1905 are proposed and a new diagnosis for the genus is given. Two new species (based on males) from the Saharo-Arabian region are here described: Bradepyris jordanicus, sp. nov. and B. baleariensis, sp. nov. A brief revision, with a key to the males and females of all species of this genus, and the first male genitalia descriptions are also provided.

A new sepioline species, Sepiola boletzkyi sp. nov. (Cephalopoda: Sepiolidae), is described based on two specimens from the Aegean Sea (eastern Mediterranean). The type specimens are lodged in the Ege University Faculty of Fisheries Museum of Izmir (Turkey). The new species belongs to the Sepiola atlantica group sensu Naef, hence it is compared with the species in this group, namely Sepiola affinis, Sepiola atlantica, Sepiola bursadhaesa, Sepiola intermedia, Sepiola robusta, Sepiola rondeletii, Sepiola steenstrupiana and Sepiola tridens. The male of S. boletzkyi sp. nov. differs from all the others in having the combination of homomorphous ventral arm tips, eight enlarged suckers, subdivided into two groups, in the dorsal row of the distal part of the hectocotylus and a dorsal lobe complementing the copulatory apparatus. In females of S. boletzkyi sp. nov. the bursa copulatrix is large and, unlike all other species in the genus, has a large fungiform process towards the mantle wall. The discovery of S. boletzkyi sp. nov. increases to 12 the number of NE Atlantic- Mediterranean species of Sepiola.

A new species of Paracrobeles, P. kelsodunensis sp. nov. is described from the Kelso Dunes area, Mojave National Preserve, southern California. Paracrobeles kelsodunensis sp. nov. is particularly characterised by a body length of 469–626 μm in females and 463–569 μm in males; lateral field with four incisures, extending almost to tail terminus; three pairs of asymmetrical lips, separated by U-shaped primary axils with two long guarding processes, each lip usually with four tines along its margin; three long labial probolae, deeply bifurcated, with slender prongs without tines; metastegostom with a strong anteriorly directed dorsal tooth; pharyngeal corpus anteriorly spindle-shaped, posteriorly elongate bulbous with dilated lumen; spermatheca 24–87 μm long; postvulval uterine sac 60–133 μm long; vulva in a sunken area; spicules 33–38 μm long; and male tail with a 5–8 μm long mucro. The generic diagnosis is emended on the basis of recently described species and a key to the species of Paracrobeles is provided.

Three new species of Eburiini are described: Beraba hovorei sp. nov. from Ecuador, Eburella migueli sp. nov from Colombia and Susuacanga marcelae sp. nov. from Mexico. A new combination, Quiacaua vespertina (Monné & Martins, 1973) comb. nov., and the transfer of Eburia (Eburia) stroheckeri Knull, 1949 to Eburia (Eleutho) Thomson, 1864 are proposed. A key to species of Beraba Martins, 1997, Eburella Monné & Martins, 1973 and Quiacaua Martins, 1997 is provided. Moreover, the geographical distribution for 15 species of Eburiini is expanded. A lectotype and a paralectotype for Volxemia dianella Lameere, 1884 are designated.

The diagnosis of the Formicidae is revised, including five new, unreversed apomorphies, of which one is a unique synapomorphy. The first global male-based key to all subfamilies is provided and illustrated, and all ant subfamilies are diagnosed for males on a global scale for the first time. Three lineages of “basal ants” are assessed in detail: the Amblyoponinae, Leptanillinae, and Martialinae. The males of Martialis heureka (Martialinae) and Apomyrma (Amblyoponinae) are described. The Martialinae and Leptanillinae are diagnosed based on males, and additional diagnostic traits for the male of Amblyoponinae and worker of Martialis are provided. The placement of Scyphodon and Noonilla in the Formicidae and Leptanillinae is confirmed. Morphological characters of the Amblyoponinae, the Leptanillinae, and the Martialinae are contrasted, and potentially homologous apomorphies are signaled.

Niphargus dancaui sp. nov., previously referred to as Niphargus cf. stygius, was sampled from various groundwater sites in and near the town of Mangalia (SE Romania) and described with Movile Cave (a sulfidic, chemoautotrophically based ecosystem) as type locality. A short comparison with Niphargus stygius specimens from Slovenia was made, together with a morphological analysis of interpopulational variability. Males of N. dancaui sp. nov. were relatively large (17 mm), with long antennae, pereiopods and uropod III. Females were slightly smaller, with shorter antennae, pereiopods and uropod III. Interpopulational variability was noticed in the chaetotaxy of the telson lobes and uropod III. N. dancaui sp. nov. is morphologically very close to N. lessiniensis and N. tridentinus, two species present in northern Italy, but distinct genetically from them based on 28S rRNA sequences. Instead, the closest relative of N. dancaui sp. nov. sequenced so far for this marker is N. montanarius, which inhabits a sulfidic cave system in central Italy. The work presented here contributes to our knowledge of groundwater crustacean biodiversity in general and of the systematics of the genus Niphargus in particular.

The new genus Lobofemora gen. nov. is described from Vietnam to accommodate three new species: L. bachmaensis sp. nov. (Bach Ma National Park, central Vietnam), L. bidoupensis sp. nov. (Bidoup-Nui Ba National Park, central Vietnam) and L. scheirei sp. nov., the type species (Cat Tien National Park and Dong Nai Biosphere Reserve, south Vietnam). It is provisionally placed in the tribe Clitumnini Brunner von Wattenwyl, 1893. The genus is the only known Clitumnini which shows tegmina and sometimes alae in the males. Females show conspicuous foliaceous lobes on the median femora. Males and females of all species and the eggs of L. scheirei sp. nov. and L. bidoupensis sp. nov. are described and illustrated. An identification key to the species and a distribution map are provided. The definition of the tribe Clitumnini sensu Hennemann & Conle (2008) is slightly adapted to include the new genus and the tribal placement is discussed. The male of L. scheirei sp. nov. is able to stridulate by rubbing the outer margins of the tegmina against the subcostal and radial veins of the alae.
