Ospriocerus abdominalis (Say)

Dasypogon abdominalis Say, 1823: 50 View in CoL .

In Lavigne & Dennis (2017) this species was designated O. aeacus because Fisher & Wilcox (1997) indicated that abdominalis Say, 1824 View in CoL was an invalid name and should be O. aeacus ( Wiedemann, 1828) . However, after careful review of literature we agree with Coquillet (1898) who was dealing with Ospriocerus and with abdominalis View in CoL synonomy, and said that there was “...no necessity for replacing...” abdominalis View in CoL with aeacus .

Recognition characters: Black species; length 15–20 mm; antennal style lacking; mystax black; thorax black; scutellar setae lacking; scutellar bristles black; wings dark brown; abdomen black with segments 3–6 orange dorsally; legs black.
