. Members of this species-group are similar externally. In fact, among these new species, there were few useful external diagnostic features discovered except for some size differences and coloration with some species distinctly dorsally maculate, but most are more evenly colored. Even males and females are difficult to distinguish externally. Because of the extreme similarity of many of the species, they are collectively described here, and the species accounts only include coloration, diagnostic features (mainly male genitalia), and measurements.
