A new species of alpheid shrimp, Thuylamea shiranui, is described and illustrated on the basis of five specimens from Yatsushiro Sea, western Kyushu, Japan. It is closely related to T. camelus Nguyên, 2001, the type species of the heretofore monotypic genus Thuylamea Nguyên, 2001, known from South China, Vietnam and Singapore. The complete lack of submedian posterodorsal crests on the carapace and the relatively long antennular peduncle distinguish the new species from T. camelus. The generic diagnosis of Thuylamea is emended to accommodate the new species.

Species of the megadiverse ground beetle tribe Platynini occur on all continents except Antarctica. It has been long recognized that platynine beetles were preserved in the Eocene Baltic amber. However, thus far only a single Eocene fossil has been described to the species level. In the present paper, a new species of Platynini known only as an amber inclusion fossil is described and imaged using light microscopy and micro X-ray computed tomography. Since this species cannot be assigned to any of the recently described genera, the monotypic genus Praeanchodemus gen. n., with the type species P. punctaticeps sp. n., is erected. There is some evidence from external morphology that Praeanchodemus gen. n. is part of a lineage comprising the recent genera Paranchodemus, Rhadine, and Tanystoma. However, since some synapomorphies were not found, the true relationships of the fossil taxon remain moot.

AbstractThe genus Hirsuticyclus Neubauer, Xing & Jochum, 2019 was the first record of an exceptionally preserved land snail with dense periostracal hairs from mid-Cretaceous Kachin (Burmese) amber. Here we document four newly-discovered shells from Kachin amber, one belonging to the type species Hirsuticyclus electrum Neubauer, Xing & Jochum, 2019 and the remaining three shells belonging to a new species, Hirsuticyclus canaliculatus sp. nov. Well-preserved morphological characteristics of these two species could be clearly demonstrated under light microscopy combined with modern micro-CT scans with computer 3D reconstructions. Our new material of the type species amends the generic diagnosis based on a better-preserved shell including the peristome and operculum. The new species shows distinctive shell characteristics such as numerous spiral keels and a flaring, folded peristome interrupted by two canals. These excellently preserved fossils contribute to our understanding of the morphological diversity and evolution of these ancient members of cyclophoroids.

A second species of the previously monotypic genus Cornucistela (C. anichtchenkoi sp. nov.) is described, illustrated and compared with C. serrata Campbell, 1980 (type species). It is a first record of the genus in Iran (South Khorasan Province).

Sand bubbler crabs of the genus Scopimera are common on sandy shores in East Asia yet the taxonomy of the species remains unclear. Scopimera globosa De Haan, 1835, the type species, was described from Japanese specimens and also occurs in Korea and China. Scopimera tuberculata Stimpson, 1858, described from Japan, has been regarded a junior synonym of S. globosa, but the types had long been lost. Some workers have considered the two taxa distinct and S. tuberculata has been recorded from South China. In the present study, we confirm using male gonopod morphology and molecular analysis, that the early records of S. tuberculata from Hong Kong and S. globosa from Taiwan are in fact S. intermedia Balss, 1934. The present study regards S. tuberculata as a subjective junior synonym to S. globosa. A new species, Scopimera ryukyuensis sp. nov. from the Ryukyus, is identified and described herein. The new species is close to S. globosa but can be separated by carapace characters. The mitochondrial cytochrome oxidase I (COI) gene revealed basepair (bp) difference between the new species and other Scopimera spp. to be at the interspecific level, at least 28 bp (4.3%).

The Indo-West Pacific alpheid shrimp genus Athanopsis Coutière, 1897 is briefly reviewed. Athanopsis platyrhynchusCoutière, 1897, the type species, is reassessed using Coutière’s illustrations and morphological notes scattered throughouthis monograph of the family Alpheidae (Coutière 1899). Athanopsis brevirostris Banner & Banner, 1981, originally de-scribed on the basis of a single immature specimen missing both chelipeds, is reported and illustrated based on fresh ma-terial from Madagascar and southern Japan. Athanopsis gotoi sp. nov. is described based on two fresh specimens fromsouthern Japan, both found associated with thalassematid echiurans, and an additional, older museum specimen from In-donesia. The colour patterns of A. brevirostris, A. gotoi sp. nov., A. saurus Anker, 2011, A. rubricinctuta Berggren, 1991,and A. australis Banner & Banner, 1982, are contrasted to facilitate their identification in the field. A morphology and colour based key to all presently known species of Athanopsis is also provided.

A new species, Michaelcallianassa sinica, from the Beibu Gulf (Tonkin Gulf), northern South China Sea, is described and illustrated. The new species is readily distinguished from M. indica Sakai, 2002, the type species of the genus, by its short uropodal endopod and exopod, and elongated carpus of the minor cheliped.

The taxonomy of the genus Chrysomphalus Ashmead (Diaspididae: Aspidiotinae) is reviewed. A new monotypic genus of armored scale, Pentalaminaspis Smith-Pardo, Evans and Dooley, is described and illustrated with Chrysomphalus minutus Kotinsky, 1908 as the type species. A new species, Chrysomphalus nepenthivorus Smith-Pardo, Evans & Dooley, is described and illustrated. This species was intercepted at a U.S. port of entry on hybrids of pitcher plants (Nepenthes) originating from Thailand. Chrysomphalus greeni Leonardi, 1914 is transferred to the genus Melanaspis and Chrysomphalus degeneratus Leonardi, 1896 is transferred to the genus Diaspidiotus. A discussion and key to species of the genus Chrysomphalus are provided as well as a key to aspidiotine genera similar to Chrysomphalus.

The monotypic genus Nyleta was described by Dodd from Australia in 1926, with Nyleta striaticeps Dodd as the type species. A new species of Nyleta is now described and imaged from the remote island of Little Andaman in the Andaman and Nicobar group of Islands in the Indian Ocean. Variants of the same species were also collected from Tamil Nadu. The images of the holotype of N. striaticeps are also provided for the first time.

A new infaunal species of the rare alpheid genus Harperalpheus Felder & Anker, 2007 is described from Bahía Málaga,  Pacific coast of Colombia, based on single, incomplete holotype specimen. Harperalpheus leptodactylus sp. nov. may be easily separated from the western Atlantic type species and only other species of the genus, H. pequegnatae Felder & Anker, 2007, by several morphological characters on the first and fifth pereiopod, as well as on the antennular peduncle.
