Notes

Spilomicrus stigmaticalis is a fairly common, widely distributed species. The species contains two BINs, BOLD:ADS1706 and BOLD:ACU1243. Still, all sequences are clustered as one single taxon using the BOLD cluster analysis and the ASAP algorithm. Not only is the genetic distance between those BINs small (1.9%), they also show medium to high intraspecific variation of up to 2.2% (mean distance 0.6%). In addition to that, we were not able to distinguish both genetic clades morphologically in both sexes, not even using the genitalia. It was only possible to find identifying morphological characters to distinguish between the females. Due to the genetic and morphological proximity of both clades, we will keep them together as one species. A lectotype is designated for Spilomicrus nigripes Thomson, 1858 (Fig. 14 ).
