Sampling sites and morphological landmarks. (a) Ten sampling sites across China from which adult G. affinis were collected; city name codes can be found in Table 3. The map was generated using DAVI-GIS v 7.5.0 (http://www.diva-gis.org/). (b) Male (above) and female G. affinis (below) collected in Hangzhou in April 2016. Dots and numbers indicate the 13 landmarks used for morphometric analyses and two additional landmarks (14 and 15) used for the ‘unbending’ procedure in our Procrustes analyses. (c) Exemplary micrograph of a gonopodium showing the 51 morphometric landmarks. Nomenclature of fin rays (3, 4a, 4p, 5a) follows Rosen and Gordon108. (d–f) Exemplary photos of our sampling sites in Ankang, Chaozhou and Nanjing, respectively.
