Limonius sapphirus sp. n. and L. onyx sp. n. are described from Taiwan, representing the first record of the genus Limonius in Taiwan. We provide an updated key to the genera of the subtribe Athouina in Taiwan and general morphological information of L. eximius Lewis, 1894 and L. ignicollis Lewis, 1894, which are endemic to Japan, for comparison with the two Taiwanese species. We believe that the two Taiwanese species and L. ignicollis are closely allied, sharing morphological characteristics of the lateral carina of prothorax, prosternal spine and aedeagus.

Following study of specimens belonging to Astragalus L. sect. Ammodendron Bunge collected from northeastern Iran, two new species and a new record for Iran are described and reported. Astragalus ayatollahii Nasseh, Joharchi & F. Ghahrem. differs from A. biarjmandicus Podlech & Zarre and A. inchebroonensis Maassoumi in having longer racemes with more flowers, only white trichomes on the calyx, and one pair of leaflets in the lower leaves and two pairs in the upper leaves. Astragalus gonabadensis Nasseh, Joharchi & F. Ghahrem. differs from A. baharensis F. Ghahrem. and A. macrobotrys Bunge in characters of the calyx and legume trichomes. Descriptions, distribution maps, and comparative tables of morphological characteristics for these taxa are presented. In addition, the first record of A. excedens Popov & Kult. in the flora of Iran is reported.

Typhrasa is a rare genus that comprises two species and that has previously been reported only from Europe and North America. The present study expands the geographical scope of the genus by describing two new species – T. polycystis and T. rugocephala – from subtropical China. The new species are supported by morphological characteristics and phylogenetic analyses (ITS, LSU and tef-1α). The new species have very similar morphological characteristics and are 98% similar in their ITS region. However, T. rugocephala has two types of long gills at the same time, rarely fusiform pleurocystidia with rostrum. Detailed descriptions, colour photos, illustrations and a key to related species are presented in this paper.

Two new species of the ant genus Myrmecina Curtis, 1829 are described and illustrated based on the worker and queen castes collected in Sumatra, Indonesia under the names M. andalas sp. nov. and M. nitidiuscula sp. nov. Each species displays unique morphological characteristics. Myrmecina andalas sp. nov. is characterized by a combination of the following characteristics: head dorsally sculptured, with the ventrolateral area smooth and shiny; propodeal spine short, triangular, pointing dorsad and with a broad base; propodeal declivity vertical, with the posterodorsal angle almost 90°. Myrmecina nitidiuscula sp. nov. is characterized by a combination of the following characteristics: head dorsum largely smooth and shiny; propodeal spine triangular and pointing posteriad, with a very broad base. Updated key to Myrmecina species of Sumatra is given.

In May–June 2017 an expedition on board RV ‘Investigator’ sampled benthic communities along the lower slope and abyss of eastern Australia from off Tasmania to the Coral Sea. Over 200 sabellariid specimens of the genera Phalacrostemma and Gesaia were collected during the voyage and deposited in the Australian Museum. Here we describe two new species Gesaia csiro n. sp. (4414–4436 m) and Phalacrostemma timoharai n. sp. (1013–1093 m). We did not formally describe another species of Phalacrostemma due to poor condition of the single specimen. Gesaia csiro n. sp. is the first record of the genus from Australian waters (only a planktonic larva attributed to the genus has previously been recorded), and it can be distinguished from other congeners by the smooth surface of inner paleae, distal thecae of outer paleae with long, irregular and expanded distal fringe and circled distal margin. Phalacrostemma timoharai n. sp. differs from congeners by the following combination of characters: presence of the buccal flap, absence of tentacular filament, 18–22 pairs of outer paleae, two pairs of neuropodial cirri on first thoracic segment, and only one pair of lateral lobes on second thoracic segment. Morphological descriptions are accompanied by mitochondrial cytochrome c oxidase subunit 1 (COI) and ribosomal (16S, 18S and 28S) sequence data. A key to all Australian species of sabellariids is given.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

This paper provides the first report of the snail-killing fly genus Dichetophora Rondani, 1868 on the Korean peninsula with the discovery of two new species, D. koreana sp. nov. and D. nigricorpa sp. nov. Descriptions and illustrations of the new species and keys to the Palearctic species of this genus are given.

Summary Two new Neomisticius species, typologically and phylogenetically close to each other, are described and illustrated from dead Quercus trees and an ambrosia beetle, Platypus quercivorus. The two species share some stylet morphological characteristics, namely, they both possess a long conus occupying more than half of the total stylet length, a long crustaformeria composed of more than 160 cells (eight rows of more than 20 cells each), and a short and broad female tail with a digitate tip. They are distinguished from each other by N. variabilis n. sp. having a wide, spindle-shaped male bursa with a blunt terminus and N. platypi n. sp. having an oval bursa with a rounded terminus. In addition, the males and females of both species have three large rectal glands and the posterior end of the male testis (distal end of the vas deferens) bears three cells that seemingly function as a valve between the vas deferens and the cloacal tube. These characteristics have not been reported in other tylenchids. Currently, the genus contains only three species: the two new species and N. rhizomorphoides, which has a normal stylet with a short conus, a short crustaformeria, and lacks rectal glands and valve cells in the vas deferens. Therefore, the two new species are readily distinguished from N. rhizomorphoides and, based on the previous definition, may even represent a new genus. However, considering their phylogenetic closeness and biological similarities (e.g., association with ambrosia beetles), the generic definition of Neomisticius was emended to include these new species.

Stenosternum cordata sp. nov. and Stenosternum bifurcata sp. nov., new to science, are described, which is the first record of Hoplomegistidae from Asia. Stenosternum cordata sp. nov. is distinguished by its heart-shaped latigynal shield with two pairs of setae along the lateral margin, and two pairs of setae along the posterior margin of the sternal shield. Stenosternum bifurcata sp. nov. is distinguished by having remarkable bifurcate corniculus, six pairs of setae on the sternal shield and three pairs setae on the latigynal shield. The family Hoplomegistidae Camin & Gorirossi, 1955 is redefined and a key to adult females of species is provided.

Two new species of the genus Laena Dejean, 1821 (Coleoptera: Tenebrionidae: Lagriinae) are described from Hong Kong: Laena hongkongica sp. n. and Laena walkeri sp. n. These constitute the first record of the genus from Hong Kong, as a species previously described from nearby area Laena ovipennis Schuster, 1926, in fact originated from Zhejiang province nearby Shanghai. Both species from Hong Kong possess a wide variation in body length, which is quite unusual for this genus.
