Two new species of Cossura Webster & Benedict, 1887 were found in material collected during sampling from the terminal lobes of the Congo deep-sea fan. They were described using light and scanning electron microscopy. Cossura platypus sp. nov. has 15–17 thoracic chaetigers, a prostomium longer than it is wide, with a widely rounded anterior margin, an abruptly expanded posterior prostomial ring the same length as the peristomium, without a mid-ventral notch, a branchial filament attached to the midlength of chaetiger 3, and a pygidium with three anal cirri. Cossura platypus sp. nov. is similar to C. brunnea Fauchald, 1972 but differs in the shape of the prostomium, which is widely rounded anteriorly in C. platypus sp. nov. and is broadly triangular in C. brunnea; furthermore, C. platypus sp. nov.is uniformly pale, whereas C. brunnea has dark pigmentation. Cossura candida Hartman, 1955 differs from C. platypus sp. nov. in the conical shape of the prostomium and 24–35 thoracic chaetigers. Cossura flabelligera sp. nov. has 16–19 thoracic chaetigers, a conical prostomium, and a branchial filament arising from the posterior part of chaetiger 2; the entire body, including the chaetae, is covered by a thick mucous sheath similar to the tunic of flabelligerids. Cossura flabelligera sp. nov. resembles C. longocirrata Webster & Benedict, 1887 in the position of the branchial filament, the shape of the prostomium, and the number of thoracic chaetigers; it differs in having a thick mucous sheath. This character seems to be unique for the Cossuridae.

Okubasca Dworakowska, 1982, formerly treated as a subgenus of Empoasca Walsh, 1862, is elevated to status as a separate genus. Two new species of Okubasca from China are described and illustrated: Okubasca convoluta Yu & Yang sp. nov.; Okubasca paracalvata Yu & Yang sp. nov. Okubasca convoluta is similar to O. okubella in having the aedeagal shaft about as long as the preatrium but differs in having the aedeagus of uniform thickness in lateral view, the anal tube process straight and the face mostly black. Okubasca paracalvata resembles Okubasca calvata in aedeagal shape, but differs in having a lamellar swelling and a small tooth on the dorsal side of the aedeagus, and the vertex anterior margin rounded.

The present study tries to focus on describing two new species belonging to genus Gammarus from western Iran along the Zagros Mountains range. The most remarkable feature of Gammarus hegmatanensis sp. n. is the shape of epimeral plate 3, which is sharply pointed posteriorly with a distinct lobate anterior margin. This species has some similarities with and differences from some other species of Gammarus pulex–group such as G. parthicus and G. syriacus. The other species, G. sirvannus sp. n. with elongated eyes is similar to G. duebeni, G. lobifer, G. balutchi and G. loeffleri, but it shows prominent morphological differences and a distinct geographical distribution from these species. These new findings shed more light on the information available on amphipod fauna of Iran.

Previously, only three of seven species in the Asian genus Notacanthurus were reported both nymphs and imagoes, and no Chinese species was found. Here two new species collected from China, which are named as Notacanthurus maculatus sp. n. and N. lamellosus sp. n. respectively, are described and pictured in detail. The nymph of N. maculatus sp. n. has following combined characters: posterior margin of sternum IX straight, claws with two subapical denticles, and gills V–VI with arrow-like accessory lobes. The male imago has unspecialized anterior margin of head and Electrogena-like penis lobes. The second species N. lamellosus sp. n. is more distinguishable. Its nymph has pale dots on head, median dorsal ridges on abdominal terga I–IX, claws with five subapical denticles, and dorsal lamellae of gills II–IV divided into two portions. Anterior margin of male imago is not protruding either, forewings have less pigmented crossveins between Sc and R1, and penis lobes have apical and ventral sclerites. A key to all known nymphs of the genus is provided.

Two new species, Cleantiella ampliscutula sp. nov. and Pentias pluriarticulatus sp. nov., are reported from Korean waters with keys to all known species of the genera Cleantiella and Pentias. Cleantiella ampliscutula sp. nov. can be distinguished from its congeners by the following characteristics: the body is relatively small; pereonite 1 is expanded anterolaterally; coxal plates 2–7 are triangular; the pleon has three partial sutures; the pleotelson is widening posteriorly on the lateral margin; the flagellum of the antenna is single-articled; and the maxillipedal palps are four-articled. Pentias pluriarticulatus sp. nov. can be distinguishable from its congeners by the following characteristics: the lateral margins of the body are parallel; the anterior margin of the cephalon is slightly concave and has a small median notch; the coxal plates are invisible dorsally on pereonites 2–4, but visible on pereonites 5–7; the pleon has three partial sutures; the flagellum of the antenna is composed of nine articles; and the distal ends of the uropodal endopods are sinuous.

A new fossil ant genus, Bilobomyrma new genus, and two new species are described based on males from the late Eocene Rovno (B. ukrainica n. sp.) and Baltic (B. baltica n. sp.) ambers. We tentatively place this genus in the myrmicine tribe Formicoxenini. Bilobomyrma is characterized by its 13-segmented antennae without an apical club; by the short scape, which is subequal to the length of the first and second funicular segments together; by the shape of the second funicular segment, which is distinctly longer than the any other funicular segment except for the apical one; by the presence of notauli on the scutum; by the absence of spurs on the middle and hind tibiae. At the same time, Bilobomyrma differs from other myrmicine genera by the peculiar shape of its clypeus, having a strongly incised medially, bilobed anterior margin, and its forewing venation: the wings have three closed cells—mcu, 1+2r and 3r; the cell 3r is very short, only twice as long as its width; the distal section of veins RS and M diverge from the cell 1+2r separately.

Three species of the genus Automate De Man, 1888 are described herein, including two new species: A. anacanthopusoides sp. nov. and A. spinosa sp. nov.. Automate anacanthopusoides sp. nov. can be easily identified by the presence of a rostrum, the notch on the lower margin of the major chela, the stout minor cheliped and the cutting edge of the pollex not dentate, and by the absence of spines on the ventral margin of the propodus of the third and fourth pereiopod. Automate spinosa sp. nov. can be easily identified by the nearly straight anterior margin of the carapace, and the presence of spines on the ventral margin of the propodus of third and fourth pereiopod. A key of all species of the Automate is provided.

Two new species of the genus Pristaulacus, P. ohishii sp. nov. and P. uenoi sp. nov. are described from Japan. The former species belongs to the comptipennis species group in having the strongly concaved occipital margin, and is peculiar in the species group in having the combination of the interrupted occipital carina and a broadly rounded and shallow occipital medial groove. The latter species resembles P. ryukyuensis in having the occipital carina not interrupted, the anterior margin of mesoscutum in lateral view acute and veins M+Cu, r-m and Cu of hind wing not pigmented, but they can be easily distinguished by the coloration of mesosoma and the dark spots of fore wing.

Two new species of banjo catfish of the genus Bunocephalus are described from the upper and middle rio São Francisco basins of Brazil. Bunocephalus hartti is distinguished from all its congeners by the absence of serrations along the anterior margin of pectoral-fin spine in adults (vs. presence of serrations along the anterior margin of the spine). Bunocephalus minerim can be diagnosed from all congeners,except B. larai, by the absence of an epiphyseal bar between the paired frontals (vs. presence of the epiphyseal bar at least in adults). Bunocephalus minerim is distinguished from B. larai and other congeners, except B. chamaizelus , by having nine principal caudal-fin rays (vs. 10 principal caudal-fin rays).
