This species can only be separated from asopiis Cresson by the 

 color of the pubescence on the apical abdominal segments. This 

 pubescence is black in asopus, while in Iiector, the appressed pubes- 

 cence especially, is golden yellow. The genitalia are identical with 

 those of asopus and are therefore not figured.
