Abstract
A single male specimen of an undescribed genus of Coniopterygidae was collected in a blacklight trap in Las Cruces. New Mexico. The specimen keys out to the genus Helicoconis Enderlein of the subfamily Aleuropteryginae in Meinander's (1972) key, but genitalic studies show the need for a new generic designation. Because the genitalia of this new genus differ from all known genera of Coniopterygidae, it is difficult to make comparisons, but for descriptive purposes, the genitalia are compared to those of Helicoconis. The structures referred to here as ectoprocts are probably equivalent to the ectoprocts of Helicoconis but may represent other structures.
