In Colombia, seven species have been recorded; here, based on the description of new species, we increase the number to 19. Diagnoses of all of them are presented. Twelve new species are described based on nymphs (<em>B. acanthosternus </em><strong>sp. nov.</strong>, <em>B. caldensis</em> <strong>sp. nov.</strong>,<em> B. colobranchius</em> <strong>sp. nov.</strong><em>,</em> <em>B. colombiensis </em><strong>sp. nov.</strong>, <em>B. dicyrtus</em> <strong>sp. nov.</strong>, <em>B. huilensis </em><strong>sp. nov.</strong>,<em> B. ironmaiden</em> <strong>sp. nov.</strong>, <em>B. notospinae </em><strong>sp. nov.</strong>,<em> B. proterochaetus</em> <strong>sp. nov.</strong>, <em>B. speciosus</em> <strong>sp. nov.</strong>, <em>B. unbranchomerus</em> <strong>sp. nov.</strong>, and<em> B. wiphala</em> <strong>sp. nov.</strong>). An identification key is developed for the species from Colombia and new characters for nymphs of <em>Baetodes</em> are proposed. </span></span></span></p> <p> </p> 2026-01-21T00:00:00+13:00 Copyright (c) 2026 https://www.mapress.com/zt/article/view/zootaxa.5750.3.2 <strong>A new stonefly species <em>Neoperla lamesae</em> sp. nov.

The description includes all the life stages from egg to adult, confirmed to be from the same species using DNA barcoding. The male adult penis closely resembles a locality morphotype of <em>N. recta</em>. The associated female adult is differentially diagnosed against the <em>N. recta </em>female lectotype by the vaginal sclerites and the polygonal chorion pattern of the egg. The COI data suggest species divergence of two <em>N. recta</em> male penis morphotypes, the Makiling and Imugin morphotypes. The observed COI divergence and previously documented penis variability of <em>N. recta</em> suggest a reevaluation of the species complex.</span></span></span></p> <p> </p> 2026-01-21T00:00:00+13:00 Copyright (c) 2026 https://www.mapress.com/zt/article/view/zootaxa.5750.3.3 <strong>Four newly recorded species of the family Coleophoridae (Lepidoptera: Gelechioidea) from Korea</strong> 2026-01-20T11:14:49+13:00 JUN-MO KOO taran9539@gmail.com SOOWON CHO chosoowon@gmail.com <p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">We report four species of the family Coleophoridae (Gelechioidea) for the first time in Korea: <em>Coleophora citrarga </em>Meyrick, 1934;<em> C. helgada </em>(Anikin, 2005); <em>C. obscuripalpella </em>Kanerva, 1941; and <em>C. varilimosipennella </em>Li &amp; Zheng, 2000.

The new species differs from all known species of <em>Actinopyga </em>in possessing a cucumariid-type of calcareous ring accompanied by slender, straight, terminally forked rods in the body wall, unlike the thick, usually well-branched rods of other species of the genus, setting it apart from all known congenerics. Of the two additional records one is another holothuriid herein attributed to the Indo-West Pacific species <em>Holothuria</em> (<em>Selenkothuria</em>) <em>erinacea</em> Semper, 1868. It is suspected to be a juvenile of this species in possessing, in addition to the perforated rods and plates in the body wall, well-formed tables, suspected to be a juvenile character, as pertains in its consubgenerics <em>H.</em> (S.) <em>parva</em> Krauss (in Lampert, 1885) and <em>H</em>. (<em>S</em>.) <em>moebii</em> Ludwig, 1883.

The mature spores were quadrate and hemispherical in lateral view, measuring 8.1±0.4 (7.1–8.8) μm in length, 13.5±0.4 (12.1–13.8) μm in width, and 11.8±0.4 (10.6–12.5) μm in thickness (n = 50). Each spore possessed four shell valves and four pyriform polar capsules measuring 4.0±0.2 (3.5–4.2) × 3.1±0.2 (2.7–3.5) μm. Morphological comparisons revealed distinct differences from previously described <em>Kudoa</em> species. Sequence analysis of the partial LSU rDNA further confirmed that this species did not match any known <em>Kudoa</em> species. Furthermore, the phylogenetic tree showed that it clusters with muscle-infecting <em>Kudoa</em> species but is distantly related to brain-infecting taxa. Based on morphological and molecular evidence, we describe <em>Kudoa stigmatias</em> <strong>sp. nov.</strong> as a novel species, representing the first documented case of myxosporean infection in <em>Chaeturichthys</em> species.</span></span></span></p> <p> </p> 2026-01-21T00:00:00+13:00 Copyright (c) 2026 https://www.mapress.com/zt/article/view/zootaxa.5750.3.9 <strong>Plecoptera primary types in the Canadian National Collection of Insects, Arachnids & Nematodes (CNC)</strong> 2026-01-20T11:19:56+13:00 DAVID K.
