A background study is important for the conservation and stock management of a species. Terapon jarbua is a coastal Indo-Pacific species, sourced for human consumption. This study examined 134 samples from the central west and east coasts of Peninsular (West) Malaysia and East Malaysia. A 1446-bp concatenated dataset of mtDNA COI and Cyt b sequences was used in this study and 83 haplotypes were identified, of which 79 are unique haplotypes and four are shared haplotypes. Populations of T. jarbua in Malaysia are genetically heterogenous as shown by the high level of haplotype diversity ranging from 0.9167-0.9952, low nucleotide diversity ranging from 0.0288-0.3434, and high FST values (within population genetic variation). Population genetic structuring is not distinct as shown by the shared haplotypes between geographic populations and mixtures of haplotypes from different populations within the same genetic cluster. The gene flow patterns and population structuring observed among these regions are likely attributed to geographical distance, past historical events, allopatric speciation, dispersal ability and water currents. For instance, the mixture of haplotypes revealed an extraordinary migration ability of T. jarbua (>1200 km) via ancient river connectivity. The negative overall value of the neutrality test and a non-significant mismatch distribution are consistent with demographic expansion(s) in the past. The median-joining network concurred with the maximum likelihood haplotype tree with three major clades resolved. The scarcity of information on this species is an obstacle for future management and conservation purposes. Hence, this study aims to contribute information on the population structure, genetic diversity, and historical demography of T. jarbua in Malaysia.

Historically, different authors have used different page numbers, and sometimes different years for these publications, which has caused chaos in the citations. Herein, accurate dates of publications for this work, and correct page numbers that should be used are provided and discussed. Mei-Ying Lin, Si-Qin Ge.A new species of one of the basal families among extant Dermaptera, Pygidicranidae, is described from mid-Cretaceous amber of Myanmar based on two females and a male. Astreptolabis laevis sp. nov., belongs to the extinct subfamily Astreptolabidinae, sharing the diagnostic combination of features typical of this group, such as the well-developed compound eyes, large pronotum, and straight and tubular cerci. The discovery of a male with its genitalia partly exerted permits characterization of traits for the subfamily and provides further information on the uniqueness and affinities of the subfamily. In addition, the extended hind wing allows for a comparison between the folding mechanism between these fossils and their modern counterparts, demonstrating considerable conservatism in hind wing evolution among Dermaptera. Yue Mao, Michael S. Engel, Dong Ren, Taiping Gao.A new genus of the spider family Deinopidae C.L. Koch, 1850 is described from Asia Asianopis Lin & Li gen. nov., with A. zhuanghaoyuni Lin & Li sp. nov. as the type species. The new genus is divided into two species groups, of which the liukuensis-group includes two species A. dumogae (Merian, 1911) sp. reval. comb. nov. (♀) and A. liukuensis (Yin, Griswold & Yan, 2002) comb. nov. (♂♀); and the zhuanghaoyuni-group comprises five species A. celebensis (Merian, 1911) comb. nov. (♂), A. konplong (Logunov, 2018) comb. nov. (♂), A. wangi Lin & Li sp. nov. (♂♀), A. wuchaoi Lin & Li sp. nov. (♂♀), and A. zhuanghaoyuni Lin & Li sp. nov. All previously described species are transferred from Deinopis MacLeay, 1839. Deinopis scrubjunglei Caleb & Mathai, 2014 is treated as a junior synonym of Asianopis liukuensis comb. nov. Yejie Lin, Lili Shao, Ambros Hänggi, John T.D. Caleb, Joseph K.H. Koh, Peter Jäger, Shuqiang Li.The primitively segmented spider genus Qiongthela Xu & Kuntner, 2015 consists of seven species that are distributed in Hainan Island, China and southern Vietnam. Of the seven species, five are known from Hainan Island. In this study, four more Qiongthela species collected from Hainan Island are diagnosed and described as new to science based on morphological characters Q. baoting sp. nov. (♂♀), Q. qiongzhong sp. nov. (♂♀), Q. sanya sp. nov. (♂♀), Q. yinggezui sp. nov. (♂♀). To facilitate future identification, the GenBank accession codes of the DNA barcode gene, cytochrome c oxidase subunit I (COI), for all the type specimens are also provided. Li Yu, Fengxiang Liu, Zengtao Zhang, Yan Wang, Daiqin Li, Xin Xu.New records of 14 stygobiont crustacean species pertaining to six Malacostraca orders from 32 cenotes are presented, with their associated caves of the state of Yucatan, Mexico, together with an individual account for each species. Species composition of most of the investigated cenotes is examined for the first time. A thermosbaenacean and two amphipod species were not formally recorded to the cenote ecosystems of the state of Yucatan prior to our research. Distribution data of a cirolanid isopod previously known only from its type locality is also provided. Barcodes of mitochondrial cytochrome c oxidase subunit I for the reported peracarid species previously lacking this information have been included in present study as tools for species identification and a baseline of further molecular genetic analyses. Dorottya Angyal, Efraín M. Chávez-Solís, Luis A. Liévano-Beltrán, Benjamín Magaña, Nuno Simões, Maite Mascaró.Phyllodiaptomus (Phyllodiaptomus) roietensissp. nov. was collected from temporary water bodies in Roi Et and Nakhon Ratchasima provinces in northeastern Thailand and Kampong Thom Province in central Cambodia. The new species is closely related to Phyllodiaptomus (P.) surinensis Sanoamuang & Yindee, 2001 in that it shares common morphological characters in the males urosomites 2-3, P5 intercoxal sclerite, right P5 Exp-2, and left P5 Exp. Minor differences on the right antennule, right caudal ramus, P5 basis and Enp exist. The females differ in their Pdg 5, genital double-somite, and P5. An updated key to the species of the genus Phyllodiaptomus Kiefer, 1936 is provided. La-Orsri Sanoamuang, Santi Watiroyram.
