Diagnosis. This species can be separated from all other species in the genus except other species of the bicolor species-group by the combination of the naked eye, absent arolia, and metasomal terga mostly orange ( Fig. 18 View FIGURE 18 ). From other species of the bicolor species-group females can be distinguished by the combination of the partly spatulate mandible with two outer teeth, 2–3 small teeth on outer spatulate area and a large inner tooth, the forewing with cells as dark as the rest of the wings, face, mandible and femora with yellow maculations, mesepisternum all dark or with a little yellow maculation. Males can be distinguished by having 4–5 similar, pointed, evenly spaced mandibular teeth and T7 with the median spine longer and broader than the narrow lateral spines; its width half that of the concavity between it and the lateral spines, and its apex broadly rounded.
Description. FEMALE. Lengths: head 3.4–3.5 mm; scutum 2.2–2.4 mm; forewing 7.7–8.4 mm; body 8. 5–9.0 mm. Head and mesosoma black except yellow maculation as follows: clypeus with W-shaped cross-band of irregular width or marking absent, outer margin of paraocular area, posterior vertex with a very short cross-band, basal portion of mandible, pronotal lobe, mesepisternum narrowly behind omaulus, narrow lateral margins of scutum and axilla, narrow subapical cross-band on scutellum, fore and mid femora and tibiae anteriorly, hind femur on distal half of anterior face, usually entire hind tibia and most of tarsi; metasoma orange except indistinct yellowish-orange cross-bands generally on T1–T5; T6 laterally; translucent posterior margins on scutellum (yellowish) and T1–T5 (orangish); forewing dark with cells as dark as rest of wing. Structure ( Fig. 18 View FIGURE 18 ). Preoccipital ridge weakly lamellate; eye naked; clypeus ventral edge straight, crenulate; mandible partly spatulate, 2 outer teeth, 2–3 small teeth on outer spatulate area, a large inner tooth; pronotal lobe strongly lamellate; omaulus lamellate; forebasitarsus short and broad, length, 0.6x foretibia length, 3.3x its width; arolia absent; T1–T5 without lateral spines; T6 rounded laterally, slightly lobate, without spine, extended posteriorly, distinctly cleft posteromedially.
MALE. Lengths: head 2.8–3.2 mm; scutum 1.8–2.0 mm; forewing 6.3–6.8 mm; body 6.8–7.7 mm. Colour as in female except: clypeus completely to partly yellow (dorsolateral region black), mandible yellow except apically, T7 yellowish-orange. Structure ( Fig. 18 View FIGURE 18 ). preoccipital ridge weakly lamellate; eye naked; clypeus ventral edge straight, 2 mediolateral tubercles; antennal flagellum 0.87x eye, 3.2x scape lengths; mandible with 4–5 similar, pointed, evenly spaced teeth; omaulus lamellate; forebasitarsus sparsely pubescent, with moderately long posterior fringe; forebasitarsus length 0.6x foretibia length, 0.3x its width, not distinctly expanded distally; hind basitarsus wide, length 2.5x width; arolia absent; T1–T4 without lateral spines or swelling; T5 slight posterolateral swelling; T 6 in one plane extended posteromedially, with small ventrolateral spine, posterolateral and posteromedian tubercles, latter slightly emarginate posteromedially; T7 with narrow posterolateral spine (narrower than length), apically rounded median spine, concavity between median and lateral spines 1.5x median spine width; terminalia as in P. cordatum (cf. Fig. 16 View FIGURE 16 ).
Distribution. This species appears to be widespread across the northern part of the Afrotropical Region ( Fig. 19 View FIGURE 19 ).
Biology. It has been collected on flowers of Phaseolus lunatus (Fabaceae) , Stachytarpheta augustifolia (Verbenaceae) and Stylosanthes erecta (Fabaceae) ( Eardley and Urban 2010).

Discussion. The specimens from Tanzania (Morogoro region), Ghana (Stingless bee research station road), Gabon and Cameroon are unusual in that they have a wide pronotal lamella. The syntypes of Anthidium bouyssoui could not be located in the TMSA where they were originally deposited.
