I have compared the genitalia of aethiops and sichela with those of Orthomiella 

 pontis sinensis and O.p. rovorea and several species of oriental Nacadnba. They had 

 no similarity, and for this reason I erected the genus Psendonacaduba. 



In 1938 {Trans. R. ent. Soc. Lond. 1938 : 125, 146) Corbet published a revision of 

 of the Malayan species of the Nacaduba group, in which he stated " The genus 

 Petrelaea Toxopeus (1929, Tijds. Ent. 72 : 242), type Petrelaea dana varia Toxopeus 

 (1929) . . . includes P. dana de Niceville and certain African forms in the sichela 

 group".
