[Chloealtis occasionally lacks a distinct medio-longitudinal carina on the vertex and will key to this point. Chloealtis males can be distinguished from Orphulella by the expanded tips of the tegmina; in Orphulella the tegmina are not expanded apically. Females of Chloealtis are medium sized (20 mm to 30 mm in length) and usually have abbreviated tegmina; females in Orphulella have tegmina approximately the length of the abdomen and they are smaller (less than 20 mm in length).]
