Material examined. ANGOLA : 1 male , [CAW 804AA], Moxico Province , Cuanavale River , Site 12— Cuanavale River tributary at confluence, at light, -13.1233 , 18.89875 , 18/xi/2016 , I.S. Ferreira . Diagnosis. Suggested by Malicky (1993) to be a member of subgenus Argyrobothrus in Oxyethira with members of which it shares the curious phallic structure, but in other features this species is most closely similar to Ox. minima Kimmins 1951 , from Myanmar , which also shares the arrangement of small rounded inferior appendages and a short, rounded ventral plate. Distribution. Described from the Seychelles and here reported from Angola . Remarks. Specimens from Guinea and Mali described and illustrated by Gibon (1987b) as ‘ Stenoxyethira cf. minima’ , resemble this species closely, and possibly could also represent Ox. sechellensis .
