Two new species of Grandidierella Coutière, 1904 from Singapore waters are described based on specimens collected during the Comprehensive Marine Biodiversity Survey (CMBS) between 2010–2015. Grandidierella pawaiensis sp. nov. differs from the rest in the genus by a combination of characters; (1) gnathopod 1 carpus proximoventral corner with apically acute process, (2) inner face of carpus of gnathopod 1 proximoventral corner with curved process, (3) proximal margin of dactylus of gnathopod 1 male with excavation, and (4) gnathopod 2 basis anterior margin crenulate. Grandidierella sungeicina sp. nov. on the other hand, is distinguishable from other related species of Grandidierella found in the tropical region by its paired mid-dorsal projections on pereonites 2 to 5, 1 ventrodistal triangular projection on pereonite 4, and gnathopod 2 ischium with 1 large trapezoid projection.

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.

Two new shrubby species of Clusia sect. Cordylandra are described and illustrated. The male flower of Clusia nogueirae presents an androecium forming a conical volcano-like synandrium around a well-developed pistillode covered with resin. The male flower of Clusia ibiapabensis, on the other hand, presents an androecium of free claviform stamens, forming a broad torus-like structure around a well-developed pistillode. The two species occur in regions of brejos de altitude in the plateou of Ibiapaba, Ceará state, northeastern Brazil.

Recent botanical explorations in western Mexico, as part of a taxonomic revision and a phylogenetic analysis of the genus Cosmos, have resulted in the discovery of two new species. The novelties belong to Cosmos section Discopoda and are described and illustrated. Morphologically, Cosmos pseudoperfoliatus resembles C. jaliscensis, C. peucedanifolius, C. palmeri and C. scabiosoides, but differs from them in having 4–7 leaf pairs on the stem, leaves tomentose on both faces, trullate external phyllaries, yellow disk florets with 4–5 lobes, and corky-tuberculate achenes. On the other hand, Cosmos ramirezianus is morphologically similar to C. montanus, but differs by its coriaceous and pinnatisect leaves, yellow internal phyllaries, yellow disk florets with light purple lobes, and by the persistence of paleae during fruiting. Phenology, distribution and habitat are provided as well as a key for the identification of the species in Cosmos section Discopoda. Recent botanical explorations in western Mexico, as part of a taxonomic revision and a phylogenetic analysis of the genus Cosmos, have resulted in the discovery of two new species.

Two new morphospecies of the rotifer genus Testudinella (Rotifera, Monogononta, Testudinellidae), T. bicorniculata sp. nov. and T. elongata sp. nov., are described from marine psammon collected in the Mediterranean. T. bicorniculata sp. nov. is characterized by two antero-lateral lorica projections; dorsal and ventral anterior margins undulate with shallow median sinus; foot opening sub-terminal, inverted U-shaped; distal foot pseudosegment short; fulcrum with proximal opening. T. elongata sp. nov. is characterized by its strongly elongate and striate lorica; dorsal anterior margin tri-lobed; ventral margin projecting, almost straight; foot opening sub-terminal, inverted U-shaped; distal foot pseudosegment long; fulcrum with proximal opening. The new species are related to T. obscura Althaus, 1957, which is redescribed. Brief descriptions of the external morphology and trophi, as well as biogeographical information are provided for the other Testudinella species reported from marine and brackish environments. T. pseudoclypeata Bērziņš, 1943 is synonymized with T. elliptica (Ehrenberg, 1834).

Two new species of Aricidea Webster, 1879 (Paraonidae), Aricidea (Acmira) anusakdiisp. nov. and Aricidea (Aricidea) thammapinanaesp. nov. were collected from 10–26.5 m depth, in soft bottoms with mud mixed with sand and shells at Songkhla Sea, the Gulf of Thailand between 2011–2018. Aricidea (Acmira) anusakdiisp. nov. is clearly distinguished from other species of the subgenus Acmira by having a rounded bilobed prostomium divided by a slight notch on the anterior margin; red pigments on the subdistal to the tip of each branchia (new character); two prebranchial chaetigers; 48–68 pairs of branchiae; and modified neurochaetae as strong curved spines with blunt shafts surrounded by pubescence from chaetigers 19–44. On the other hand, Aricidea (Aricidea) thammapinanaesp. nov. can be separated from other members of the subgenus Aricidea by the presence of a biarticulated median antenna; distinctive notopodial lobes as broad triangular with short distal protuberances on chaetiger 3, 4–8 pairs of branchiae; and modified neurochaetae as bidentate neurochaetae with a long pubescent subterminal arista on the concave side. All data have been archived and are freely available from the Dryad Digital Repository (https://doi.org/10.5061/dryad.hqbzkh1cn).

This paper includes descriptions of a new species of Cinara and one of Micromyzus.The species of Cinara belongs to the species group in which the base of the cornicle hears both heavy and fine setae. In other members of this group the heavy and fine setae are evenly distributed over the surface of the base of the cornicle, but in the species described here the fine setae are clustered around the orifice and the heavy ones are closer to the margin of the base than in related species (Fig. 4). Another difference is that the dorsum of the abdomen is heavily sclerotized rather than having the small, isolated sclerites characteristic of the other members of this species group.

Although almost 50 species of Galumnidae (Oribatida) have been recorded in Japan, more species remain undiscovered. In the present work, we propose two new species from southern Japan, Trichogalumna boninensis sp. nov. and T. ohkuboi sp. nov., and provide an additional description of T. imperfecta Ohkubo, 1984. Trichogalumna boninensis sp. nov. can be distinguished from other closely related species by the smaller body size, and the large granular ornamentation along the hinges of the pteromorphs. Trichogalumna ohkuboi sp. nov. can be distinguished from other closely related species by the absence of granular ornamentation on the proximal margin of the dorsal surface of the pteromorph, the striated genital plates, the absence of granular ornamentation on the humeral region of the notogaster, the short lamellar and interlamellar setae, the distantly located porose areas of A1 and A2, and the different number of epimeral setae. Furthermore, we present data on habitat ecology and biogeography of Japanese species of Trichogalumna, and a key is provided for identification of all species in the world.

The first records of the family Nicoletiidae in Iran are given, based on material from subterranean habitats in Fars Province. Two new species are described, one belonging to a new genus of Atelurinae, Persiatelurina farsiana gen. n. sp. n., the other to the genus Lepidospora but representing a new subgenus, Brinckiletinia subgen. n., this new subgenus is close to the subgenus Brinckina, but lacks scales on the thorax. Both new taxa are compared with related species. Nipponatelurina caucasica Kaplin, 2016 is transferred to Persiatelurina caucasica n. comb. The new atelurine was collected in Momtaz and Khan Caves and Lepidospora (Brinckiletinia) malousjanica sp. n. was found in Malousjan Cave. An additional specimen of Lepidospora was collected in Momtaz Cave, and although its specific identity is not clear, it represents a third taxon belonging to the subgenus Brinckina. Data about the habitats of these subterranean Nicoletiidae are presented.

The species herein described both belong to the family Menoponidae. One of these species, collected by me from a Waxbill (a passerine bird) at Onderstepoort, Pretoria, belongs to the genus Machaerilaemus Harrison, the other, taken from a Sandgrouse in the Rustenburg District, Transvaal, by Mr Powell, together with specimens of a species of Degeeriella, I am placing in a new genus, for which I propose the name Neomenopon. These two new species are extremely interesting, in that they both possess a chitinous framework extending backwards from the anterior margin of the head for the support of the mandibles, a structure previously only known to occur in the genus Eomenopon Harrison, which was established partly on account of this structure. A similar structure, however, also occurs in a small unidentified species of Menopon taken from a Little Banded Goshawk (Astur polyzonoides) at Onderstepoort. This species may eventually prove to be sufficiently distinct in other details from the type of Menopon to warrant the founding of a new genus for its reception.

Three species of mysids belonging to two genera from the southern Indian Ocean (Lat. 31–55°S and Long. 45°E) are reported, of these two species - Siriella brevispina and Euchaetomera spinosa - are recorded as new to science. Siriella brevispina shares characters associated with the Brevicaudataand Thompsonii-groups and is distinguished from related species by the presence of a short telson, the anterior margin of the carapace with a triangular rostral plate, the labrum with a long process on the anterior margin, and the inner margin of the uropodal endopod showing an alternating arrangement of long and short spines. Euchaetomera spinosa is distinguished from the morphologically similar species Euchaetomera zurstrasseni by the absence of an ocular papilla, presence of a distal suture in the antennal scale, and the arrangement of spines on the telson.
