Praz et al . (2022) identified two putative lineages that could refer to the taxon A. poupillieri , for which the type series has been lost. Wood (2023) designated a neotype (see Fig. 4 ) for the lineage called poupillieri #2 by Praz et al . (2022) . This species now has an unambiguous status. The identity of poupillieri #1 appears to be A. gregaria based on type examination and the generation of additional sequences from Morocco ( Fig. 4 ). This species resembles A. poupillieri morphologically, but the terga are much more densely punctate, including punctures on the declivity of T1 (cf. A. wilkella ( Kirby, 1802 )) . However, two specimens conforming to this concept had identical barcodes to the barcode of A. fuliginata used in the analysis of Praz et al . (2022) . This A. fuliginata specimen (HYMAA289-22) conforms to the type concept ( Fig. 5A–D ) in that it has short dark hairs on the scutum underlying the longer light brown scutal hairs ( Fig. 5B ), the hind tibiae are orange, the terga are almost impunctate, including the declivity of T1 ( Fig. 5C ), and the terminal fringe is dark ( Fig. 5D ). There appears therefore to be some barcode sharing in this group of species; no taxonomic action is taken, and all sequences are grouped together in a broad gregaria / fuliginata aggregate for the time being. This aggregate shows a very low average ‘intraspecific’ variation of 0.37% (range 0.00–0.68%) and has a bootstrap support of 96. In contrast, a sister clade was formed next to this aggregate consisting of specimens from Morocco originally identified as A. russula Lepeletier, 1841 with dark terga and one specimen from Tunisia with red-marked terga. This clade was separated from the gregaria / fuliginata aggregate by an average of 1.92% (range 1.61–2.74%), and has low average intraspecific variation of 0.44% (range 0.00–1.00%); this clade consequently has a bootstrap support of 94. Morphologically, it cannot be confused with either A. gregaria or A. fuliginata , and so it is described as A. prazi sp. nov. (see diagnosis section for this species).
