The myrmicine genus Rotastruma is a rarely collected arboreal ant group and only two species, R. recava Bolton and R. stenoceps Bolton, are known from the Oriental Region. A new species, R. epispinasp. nov., is described from Cambodia based on the worker and queen castes. The new species is distinguished from R. recava and R. stenoceps by having the propodeal spine directed upwards and elongated peduncle of the petiole. Herein, we provide an update to the identification key and diagnostic characters for the genus Rotastruma.

The genus Charaea Baly is distributed in the eastern Palaearctic, Himalayas, China and adjacent countries of the Oriental Region. Currently, 59 species of the genus Charaea have been recorded. The species of Charaea is characterised with a robust tubular aedeagus that terminates with a more or less distinct apical process with the Charaea coomani group having an internal sac with long sharp lateral sclerites. Up to now, 13 species of this group have been described in the Oriental Region, four of which are found in Vietnam. Charaea dinhcuongisp. nov. is described as a new species, based on specimens collected from Phu Quoc Island in southern Vietnam. Colour photographs of habitus and body details and DNA barcode sequences are presented. An identification key is provided for all Vietnamese species from the Charaea coomani group.

A new species of Galumna (Galumna) (Oribatida, Galumnidae) are described from a sample of grass rhizosphere, from a meadow of the Tam Dao National Park, Northern Vietnam. Galumna (Galumna) dkrivolutskyi sp. nov. differs from G. pseudotriquetra Ermilov, 2015(b) by the larger body size, bothridial heads slightly developed unilaterally and by the absence of sejugal suture medially. A supplementary description of G. discifera Balogh, 1960 is present based on Vietnamese specimens. Morphological additions to description of the Vietnamese species, G. acutirostrum Ermilov & Anichkin, 2010, are given. An identification key to known species of Galumna (Galumna) from the Oriental region is 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.

Stenogiffardia bifurca sp. nov. is described from a series of specimens collected in the former Antananarivo, Fianarantsoa, and Toliara Provinces of Madagascar. This is the first record of the genus,Evans, 1977 (Hemiptera: Cicadellidae: Deltocephalinae) from Madagascar, which is now the third genus of the tribe Chiasmini known from the island.
