 Description. General color brownish. Head light brown with central part ochraceous; clypeal area setose; Mline slightly visible (Fig. 2A) but in some specimens with a brown outline; lappets light brown; gena and parietalia light brown; postfrontal line U-shaped; antenna dark brown with the closest part to scape light brown; scape dark brown; palpi brown. Pronotum, brown to dark brown with the median part lighter and margins dark brown covered with setae (Fig. 2A). Legs, femora light brown, tibia and tarsi darker. Wing membrane brownish and veins brown (Fig. 2B). Sternum IX with dark posterior strip (Fig. 2C). Cerci dark brown.   
 Male. Forewing length 6.6–8.7 mm (n= 9). Hammer a truncate cone, wider than long (Fig. 2C). Penial armature with no membranous lobes (Fig. 2D); apical portion irregular and robust, projecting distinctly forward of the hooks. In dorsal view (Fig. 2E), large gonopore projecting ventrally, border expanding shortly; keel very large and Y-shaped; apical part narrowing gradually to median part, then widening again, being slightly wider at base. In ventral view (Fig. 2D), hooks regularly curved, concave ventrally, with no pointed tips and acute apically. In lateral view (Fig. 2F), apex expanded dorsally, a deep depression near the level of basal part of hooks. Presence of patch of small sparse sclerotized spines covering the surface of the lower apical part of the penial armature in dorsal and ventral views, also in ventral view in the middle of basal portion of penial armature and in apical part closest to the hooks (Fig. 2G).   
 Female and Nymph. Unknown.   
 Remarks. The apical structure of the penial armature of A. zantedeschia. resembles A. caraa De Ribeiro & Froehlich 2007. However, a major difference is the position of the gonopore, which projects ventrally, whereas in A. caraa it projects apically. Additionally, the wing length of A. caraa is longer, male forewing length 11.8 mm, and the hammer is more pointed than in A. zantedeschia.   
 Etymology. “ Zantedeschia” refers to the genus of the South African arum lily flower, Zantedeschia aethiopica (L.) Spreng, which the spathe resembles the gonopore of penial armature of A. zantedeschia.
