The first representative of the genus Cerapus in Malaysian waters, Cerapus bumbumiensis sp. nov. is described from specimens sampled from Pulau Bum Bum, Sabah (east Malaysia). The main identifying characteristics of this new amphipod species are: pereonites 1, 2 with constriction; male gnathopod 2 carpochelate, carpus large with long defining posterior tooth and well-developed anterodistal tooth; pereopod 6 coxa with fine hair/fringe setae ventrally; and telson with deep cleft. An updated identification key for the 23 known species in the genus is also presented.

A new amphipod species of the genus Elasmopus Costa, 1853 is described based on material collected from intertidal rocky shore, near the Suape Harbor, coast of the Brazilian state of Pernambuco. The new species may be recognized by the propodus of gnathopod 2 suboval, slightly tapering distally, palmar margin not defined by a stout seta, spine, or palmar corner, with a subdistal blunt tubercle, posterior margin covered by a dense fringe of plumose setae, and posterior margin of basis of pereopod 7 castelloserrate. This is the ninety-fifth species of the genus Elasmopus described worldwide, the most diverse genus in the family Maeridae Krapp-Schickel, 2008, and the eighth species recorded from Brazilian waters. An identification key to Brazilian species of Elasmopusis also provided.

A new species of freshwater Amphipod, Gammarus topkarai sp. nov., collected from Ivriz Creek, Tarsus Province, South Anatolia, is described and illustrated. The new species belongs to Gammarus pulex-group and shows similar characteristic features with Gammarus agrarius G. S. Karaman, 1973. Absence of well developed dorsal elevations on the urosome segments, smaller body length and relatively lower endopod/exopod ratio of third uropod are the most obvious features differ from G. agrarius. A detailed morphological description and illustrations of new species are given and differences from related species are discussed. An updated identification key of Gammarus taxa reported from Turkey, up to date, was also presented.

Seven species of freshwater crabs from three families are recorded from and around the Danum Valley Conservation Area in Sabah, Malaysian Borneo: Thelphusulacapillodigitus sp. n., Thelphusuladicerophilus Ng & Stuebing, 1990, Arachnothelphusaterrapes Ng, 1991, Terrathelphusasecula Ng & Tan, 2015, Parathelphusavalida Ng & Goh, 1987 (new record) (Gecarcinucidae); Isolapotamoningeri Ng & Tan, 1998 (Potamidae); and Geosesarmadanumense Ng, 2002 (Sesarmidae). The new species of Thelphusula Bott, 1979, can be distinguished from all congeners by a unique combination of morphological features, most notably the presence of dense patches of short setae on the fingers of the adult male chelipeds, as well as the structure of the male first gonopod. Arachnothelphusaterrapes is confirmed to be a phytotelm species. A key to all species in the conservation area is provided.

Dichotomius (Dichotomius) quadrilobatus new species (Coleoptera: Scarabaeidae: Scarabaeinae: Dichotomiini), from western Amazonia (Brazil, Colombia, Ecuador and Peru) is described and its putative systematic position within the Dichotomius boreus species group is discussed. An updated identification key to the species of the Dichotomius boreus species group is provided. Additionally, Dichotomius (Selenocopris) fortepunctatus Luederwaldt, 1923 is recorded for the first time in Colombia.

Ferulago akpulatii (Apiaceae) is described as a new species endemic to Central Anatolia, Turkey. It is closely related to Ferulago platycarpa and F. pauciradiata, and is easily distinguished by its cauline leaf shape, inflorescence type, and fruit features. The main morphological differences between Ferulago akpulatii and related taxa are discussed, and the diagnostic characteristics, including the anatomical features of fruits, are given in detail. An identification key of Ferulago akpulatii and the morphologically closer species is also provided.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

A new species of the chirostylid squat lobster genus Uroptychodes Baba, 2004, U. fuscilineatus, is described and illustrated on the basis of a single ovigerous female from the Uraga Channel, central Japan, at depth of 250 m. The new species appears most similar to U. spinimarginatus (Henderson, 1885) and U. yapensis Dong, Gan & Li, 2021 among the 13 known congeners, but is notable in the pereopod 2 not being definitely more slender than the pereopods 3 and 4 and the remarkably spinose pereopods 1–4. A possible association of the new species with crinoid is suggested. An updated identification key to species of Uroptychodes is presented.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.
