Although there have been reports on the ichthyofauna in Singkil peat swamp, information regarding the genetic diversity of fish in this area is not available. Therefore, this study aimed to explore the use of DNA barcode method to validate the taxonomic status, as well as analyze the diversity and genetic relationships of fish found in Singkil peat swamp area, located in Aceh Province. A total of 123 DNA sequences were successfully obtained, leading to the generation of 88 haplotypes, comprising 34 species, 23 families, and 29 genera. The analysis of genetic distance was performed between various species. The results showed that the closest genetic distance of 4.04 % was between <em>Ambassis macracanthus</em> and <em>Ambassis nalua</em>, while the highest at 31.62 % was between <em>Mystus nigriceps</em> and <em>Toxotes jaculatrix</em>. <em>Cyclocheilichthys apogon</em> had the highest haplotype diversity with 6 haplotypes, while <em>Caranx tille, Oreochromis niloticus</em>, and <em>Taenioides cirratus</em> showed the lowest with 1 haplotype, respectively.

Our results indicate that the musculature and sclerites are few variable in the most part of the abdomen, however the ninth abdominal sternum presents the greatest changes related to its shape and associated muscles. Furthermore, based on our studies, we also infer that the sinergic movements of the ninth sterno-genital muscles are responsible for the protrusion, retraction and rotation of the genitalia, being responsible for the movements during the copula. In <em>Pristocera</em>, the muscles between S8 and S9 also promote secondarily the adduction and abduction of the ninth abdominal sternum. This phenomenon is interpreted as an example of exaptation. The understanding about the muscle morphology and its origin as well as its functionality are important because it may help conduct studies with other taxa in Hymenoptera with the same or different changes present in Bethylidae and arise hypotheses about the morphofunctionality in other groups.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"319 ","pages":"Pages 335-348"},"PeriodicalIF":1.5,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145473955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
