For details of multiple synonyms see Morse (2020) . Material examined. ANGOLA : 1 pharate adult male in sandgrain case, [CAW 797J], Moxico , Cuando River , Site 20— Cuando River long bridge at village, in sand, -13.0923 , 19.35946 , 16/xi/2016 , I.S. Ferreira . Distribution. This species was described from East Africa and is now known to be more widespread in tropical and southern Africa and the West Palaearctic. Remarks. Hydroptila cruciata is readily distinguished by the pair of elongate, stoutly sinuous, sclerotised structures in the male genitalia that arise above the bases of the inferior appendages, converge and usually cross distally. The pharate adult in a sandgrain case is unusual, as larvae of H. cruciata in South Africa use filamentous algae ( Spirogyra sp.) to construct their cases ( de Moor 2015 ). It could indicate that this species comprises an aphanic (cryptic, see Steyskal 1972 ) species complex.
