Kudoa spores were detected in the brains of 35% of the specimens. The mature spores were quadrate and hemispherical in lateral view, measuring 8.1\u00b10.4 (7.1\u20138.8) \u03bcm in length, 13.5\u00b10.4 (12.1\u201313.8) \u03bcm in width, and 11.8\u00b10.4 (10.6\u201312.5) \u03bcm in thickness (n = 50). Each spore possessed four shell valves and four pyriform polar capsules measuring 4.0\u00b10.2 (3.5\u20134.2) \u00d7 3.1\u00b10.2 (2.7\u20133.5) \u03bcm. Morphological comparisons revealed distinct differences from previously described Kudoa species. Sequence analysis of the partial LSU rDNA further confirmed that this species did not match any known Kudoa species. Furthermore, the phylogenetic tree showed that it clusters with muscle-infecting Kudoa species but is distantly related to brain-infecting taxa. Based on morphological and molecular evidence, we describe Kudoa stigmatias sp. nov. as a novel species, representing the first documented case of myxosporean infection in Chaeturichthys species.\n\u00a0<\/jats:p>","DOI":"10.11646\/zootaxa.5750.3.8","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T22:44:32Z","timestamp":1768949072000},"page":"429-437","source":"Crossref","is-referenced-by-count":0,"title":["Kudoa stigmatias sp. nov.
