Diagnosis. As in Acrotona and Mocyta , in Strigota the pronotal hypomera are invisible in lateral view. However, in Strigota the punctation of abdominal terga is denser, and the pronotum is not as broad as in Mocyta and most examined species of Acrotona . Strigota also has the following unusual characters: in both sexes the basal line of the abdominal tergum 8 laterally joins the base of the tergum ( Figs. 142, 145 ) while in other examined athetines the basal line is always separated from the tergum base (cf. Figs. 107, 110 ; 135, 137 ); in both sexes the base of the abdominal tergum 8 has two gland openings ( Figs. 142, 145 ); and the apical margin of the male sternum 8 with a row of microsetae on its dorsal [sic!] side ( Fig. 144 ) (like in Philhygra Mulsant & Rey, 1873).

Discussion. Casey did not specifically state in his description of Strigota that St. oppidana was the type species of Strigota ; however, while designating the type species of Noverota Casey, 1910a in the same paper, Casey stated (1910a, p. 90): “The first species may be regarded as the type, as in all other cases where the type is not specifically named”.

The type species of Strigota ( St. oppidana ) and Anaduosternum ( Ana. brevipennis ) are conspecific (see below). Therefore, Anaduosternum is a junior subjective synonym of Strigota .
