We suggest the new species should be considered as Vulnerable (VU) following the IUCN’s Red List categories. The new species occurs in dry maritime mixed low evergreen forests at elevations of 200–280 m a.s.l. and was recorded in association with termite species </span><span style="color: #050000;"><em>Globitermes sulphureus</em></span><span style="color: #050000;"> (Haviland).

Two informal species groups are recognized based on characters of the head, forewing and leg chaetotaxy. A key to species, photographs, updated morphological descriptions, and the first descriptions of the female and male genitalia of <em>Nasuconia</em> species are provided. Comparisons of cucullate setae and fine abdominal integument structures are also made using scanning electron microscopy. </span></span></span></p> <p> </p> 2023-12-01T00:00:00+13:00 Copyright (c) 2023 <strong><em>Stempellinella</em> Brundin, 1947 (Diptera: Chironomidae) from Eastern Siberia and the Russian Far East, with the description of new species</strong> 2023-12-01T12:12:20+13:00 OKSANA V.

The family comprises three subfamilies: Hybusinae, Proscopiinae, and Xeniinae, with Hybusinae as the smallest subfamily, housing the genus <em>Hybusa</em> Erichson, which contains four species endemic to Chile. Considering that the most recent comprehensive taxonomic assessment of this genus was conducted approximately three decades ago, herein we redescribe the type species of <em>Hybusa</em>, <em>H. occidentalis</em> (Westwood), based on males and females. The study includes new images of <em>H</em>. <em>occidentalis</em> body and male genitalia, along with a comprehensive pictorial key for all <em>Hybusa</em> species using available type material. Additionally, a morphological comparison between <em>Hybusa</em> and other Proscopiidae taxa is presented.</span></span></span></p> <p> </p> 2023-12-01T00:00:00+13:00 Copyright (c) 2023 <strong><em>Malakichthys formosus</em>, a new species of small seabass (Acropomatiformes: Malakichthyidae) from southwestern Taiwan</strong> 2023-12-01T12:12:14+13:00 SHING-LAI NG KWANG-MING LIU SHOOU-JENG JOUNG <p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">A new species of <em>Malakichthys </em>is described based on six specimens collected from deepwaters off southwestern Taiwan, northwestern Pacific Ocean. The new species, <em>M. formosus</em> sp. nov., exhibits distinct morphological characters, primarily characterized by the absence of chin spines, distinguishing it from other congeners with the exception of <em>M. levis</em> and <em>M. mochizuki</em>. It differs from the two species by having more lateral-line scales, a shorter distance between the snout and dorsal-fin origin, a shallower head, fewer scale rows below the lateral line, and the structure of the first anal-fin pterygiophore. Eight species are now recognized in <em>Malakichthys</em>.</span></span></span></p> <p> </p> 2023-12-01T00:00:00+13:00 Copyright (c) 2023 <strong>One new species of the genus <em>Phlugiolopsis </em>(Orthoptera: Tettigoniidae: Meconematinae) from Guizhou Province, China</strong> 2023-12-01T12:12:11+13:00 YANGYANG PAN XUN BIAN <p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: medium;"><em>Phlugiolopsi</em>s was proposed by Zeuner in 1940 with <em>Phlugiolopsis henryi</em> Zeuner, 1940. Chinese scholars Xia &amp; Liu first studied the genus in 1993 and described three new species from Wuling Mountains Area of Southwestern China, among which <em>Phlugiolopsis brevis</em> Xia &amp; Liu, 1993 and <em>Phlugiolopsis</em> <em>tuberculata</em> Xia &amp; Li, 1993 were mainly distributed in Guizhou Province. Twenty years later, Bian <em>et al.</em> (2013) described the third species of <em>Phlugiolopsis</em> from Guizhou, namely <em>Phlugiolopsis</em> <em>xinanensis</em> Bian, Shi &amp; Chang, 2013. Compared with Yunnan Province, the classification of <em>Phlugiolopsis</em> in Guizhou is far from sufficient. Herein based on new specimens deposited in Guangxi Normal University, we describe one new species from Guizhou, China. </span></span></span></p> <p> </p> 2023-12-01T00:00:00+13:00 Copyright (c) 2023 <strong>A new subspecies of <em>Purpuricenus temminckii</em> Guérin-Méneville, 1844 (Coleoptera, Cerambycidae) from China</strong> 2023-12-01T12:12:09+13:00 MAXIM LAZAREV 2023-12-01T00:00:00+13:00 Copyright (c) 2023 <strong>The tadpole of <em>Hylodes amnicola</em> Pombal, Feio & Haddad 2002 (Anura: Hylodidae): External morphology and buccopharyngeal anatomy</strong> 2023-12-01T12:12:06+13:00 RACHEL MONTESINOS ANDRÉ L.
