Suppl. material to: An integrative investigation reveals one new oriental species of Epeorus (Belovius) from China (Ephemeroptera: Heptageniidae) (ISE)

<p dir="ltr">Epeorus (Belovius) carinatus Braasch & Soldán, 1984 was thought to be distributed only in Vietnam until</p><p dir="ltr">it was recently reported in southern China. However, some morphological variations are also recognized</p><p dir="ltr">among its Chinese populations. Here, an integrative taxonomic approach, which is combined with genetic</p><p dir="ltr">analysis based on COI (mtDNA) and morphological evidence, is used to investigate the variation of this</p><p dir="ltr">species in China. The results show that E. (B) carinatus previously reported in China actually comprises</p><p dir="ltr">two species: the originally identified E. (B) carinatus and a new species, E. (B.) dentatus sp. nov. Both</p><p dir="ltr">male imaginal and nymphal stages of two species are described herein. Morphologically, these two species</p><p dir="ltr">can be distinguished from each other by (1) nymphal labrum and mandible, (2) coloration of abdominal</p><p dir="ltr">terga on both male imaginal and nymphal stages, (3) coloration of wings and (4) shapes of genitalia of</p><p dir="ltr">male imagines.</p>
