Ceraturgus niger Macquart

Ceraturgus niger Macquart, 1838: 25 .

Macquart (1838) described Ceraturgus niger “de l’Amérique boréale.” Walker (1854) later listed it from Mexico. Osten Sacken (1878) transferred it to Taracticus without explanation. Brauer (1883) did not find the stout, enlarged spine at the apex of the fore tibia that is found in Taracticus . He and Williston (1884) felt that C. niger did not belong in Taracticus . Macquart’s (1838) illustrations show five antennomeres, with the third flagellomere longer than the scape, and much shorter than the first flagellomere. He described it as a small (about 8.5 mm long), black species with grayish yellow face and front, yellowish mystax, yellowish wings, having white spots on some of the abdominal segments. Macquart’s C. niger cannot be a species of Taracticus, but no known North American species of Ceraturgus fits its description.
