Remarks:
Hamdan, Scali & Fernandes (2014) redefined flavolineatus, designated a lectotype, and confirmed Jan (1863) as the correct authorship. A record from Peru (Lehr 2002) is regarded as erroneous (Hamdan & Fernandes 2015). Previously included the populations now assigned to brazili.

|
2020 | |
Chironius gouveai Entiauspe-Neto, Lyra, Koch, Quintela, Abegg & Loebmann |
Remarks:
Previously regarded as a population of bicarinatus.
Records of bicarinatus from Argentina and Paraguay are tentatively referred to gouveai, since they are geographically much closer to records of the latter species than the former.
A record from Montevideo, Uruguay, is presumed to represent an introduced bicarinatus (Entiauspe-Neto, Lyra, Koch, Quintela, Abegg & Loebmann 2020).
