Paralectotypes: 2♀. All in ZMUN. The synonymy of D. schneideri with D. liogaster was first proposed by Lindqvist (1943). Treated here as a color form of D. liogaster, but still separated in the key, because the melanic color form of D. liogaster also has black legs, and D. schmidti has a color form with a red-marked thorax. Specimens resembling D. schneideri are also known from the mountain areas of Central Europe, e.g. from Switzerland at altitudes of 1500-1700 m (Benson 1961). Dolerus truncatus Lacourt, 1988.

The penis valve (Fig. 18) appears to be somewhat distorted, perhaps during preparation, but resembles the valve of D. ...
