The type was not located. Similarly, the holotypes of  hesseiand  nigrescenswere not studied. Their identity was based on the original descriptions (Cockerell 1932, Pasteels 1984). They are apparently colour variations of  A. eritrinum .   Diagnosis.In   A. eritrinumthe paraocular areas are yellow below, reaching diagonally to a little above the antennal sockets ( Fig. 2a, b), above which is mostly black, as are most of the genae. The female scutum is usually black, but yellow anterolaterally in some specimens, and in all males it is completely black. The scutellum is black mediolongitudinally and yellow laterally ( Fig. 2 b, d), the mesopleura are black and the metasoma is usually yellow and orange, occasionally black and yellow ( Fig. 2b). The integument between the scutal puctures is shiny and largely striate, reticulate in places, more so anteriorly.  Anthidiellum pamaehas more extensive yellow maculation, reaching near to the upper extremes of the eyes, encompases most of genae and limited on the anterolateral region of the metasoma, and it is never shiny between punctures.   Description.Female. Integument of head and mesosoma black with golden-yellow maculation on lower face, posterior vertex, upper gena, proximal mandible, pronotal lobe, anterolateral scutum (one specimen), axilla, lateral and posterolateral scutellum; legs and metasoma orange with yellow maculation on most of femora, outer tibiae and tarsi; anterior and lateral T2–T5 except translucent distal margins, most T6 (blackish anterolaterally), sometimes golden-yellow maculation on lateral T1 ( Fig. 2a–b). Scopa very pale yellow ( Fig. 3a). Lengths: face 2.1–2.3 mm; scutum 1.5–1.8 mm; forewing 5.1–5.7 mm; body 5.1–6.1 mm. Structure. Head. Epistomal suture gently incurved at epistomal pit ( Fig. 1a); lower epistomal suture projects adjacent to inner antennal socket edge ( Fig. 1a); entire preoccipital carina well developed (behind vertex and gena); scutum gently convex, uniformely punctate; omaulus broadly lamellate ( Fig. 2b); fore and middle femora with spinose vestiture posteriorly; hind basitarsus narrow (length 2.3x width) ( Fig. 3a); propodeum striate dorsally, vertical surface punctate dorsally and laterally, glabrous and shiny medioventrally. Male. Integument of head, mesosoma and metasoma black with golden-yellow maculation on lower half of face (reaching upper antennal socket), vertex, upper gena, most of mandible, pronotal lobe, axilla, sometimes a fleck on anterolateral scutum, lateral and posterolateral scutellum, most of femora, outer tibiae and tarsi, anterolateral T1, anterior and lateral T2, T3–T5 except sometimes subapical black crossband and translucent distal margins, T6–T7 ( Fig. 2c–d). Lengths: head 1.9–2.1 mm; scutum 1.2–1.4 mm; forewing 4.8–5.1 mm; body 4.5–5.5 mm. Structure. Head. Entire preoccipital carina well developed (behind vertex and gena); omaulus narrowly lamellate; fore and middle femora with spinose vestiture posteriorly; propodeum striate dorsolaterally, vertical surface punctate dorsally and laterally, glabrous and shiny medioventrally; T6–T7 posteromedian spines (T6 obtuse, T7 acute); S1–S3 unmodified; S4 with a few black, setose hairs posteromedially (about 6 slender hairs, not a comb) ( Fig. 3b); S5 with black, setose comb medially (less than half distal edge, Fig. 3b, h); S6–S8 and gonocoxa as illustrated ( Fig. 3d–h).   Distribution( Fig. 4).  Anthidiellum eritrinumseems to be widely distributed on the eastern half of Africa from Somaliato  SouthAfrica. However, one specimen was recorded from northern Namibia, which is savannah, as is the rest of its distribution.   Material examined.Type material.
