Diagnosis. This small distinct species can be identified by the unique, completely glabrous and shiny vertical surface of the propodeum. In all other Afrotropical Anthidiellum , the propodeum has either some integument sculpture or punctuation. The outer surface of the hind tibia is black circumscribed by yellow. This coloration also occurs in A. absonulum . In all other species, it is black, yellow or yellow circumscribed by orange.

Integument black with limited pale yellow maculation on ventral clypeus, lower paraocular area, lateral supraclypeus and interantennal socket area; lateral vertex, pronotal lobe, lateral scutum, posterolateral scutellum, outer, proximal surfaces of tibiae, outer surface of hind basitarsus (circumscribed by black); lateral T1–T2, mediolateral T3–T5, most T6 (lateral and anterior black); distal margins of T1–T5 black; metasomal venter blackish; scopa very pale yellow ( Fig. 24a–c View FIGURE 24 ). Lengths: face 1.7 mm; scutum 1.3 mm; forewing 3.8 mm; body 4.2 mm. Structure. Head. Epistomal suture convex above ( Fig. 1a View FIGURE 1 ); lower epistomal suture projection adjacent to opposite inner antennal socket edge ( Fig. 1a View FIGURE 1 ); preoccipital area rounded; omaulus carinate; hind basitarsus more or less parallel sided, narrow (length 2x width) ( Fig. 24c View FIGURE 24 ); propodeum coarsely striate dorsolaterally, vertical surface with small punctate area dorsomedially, remainder glabrous and shiny; distal margins of T1–T5 impunctate.

Male. Unknown.
