Scale bars: 2 mm. Diagnosis. This species is the most likely one to be confused with Saropogon pyrodes sp. nov. because of its reddish color. They are easily distinguished by the entire anepisternum of Saropogon luteus being with gold pubescence instead of white as in S. pyrodes sp. nov. Saropogon luteus also has small, with gray pubescent spots on the posterior corners of the tergites. This species is almost exclusively found in California. Body length 11-17 mm; wing length 8-10 mm.
