03AE87B3FF95FF9664E9C3F07079FA06.taxon	diagnosis	Diagnosis. This species can be distinguished from all other species of Acrotaphus by the combination of the following characters: 1) lower face 0.5 – 0.6 × as broad as high; 2) gena flat behind the eyes; 3) posterior ocelli separated from eyes by 0.1 – 0.2 × its diameter in dorsal view; 4) fore wing blackish with one yellowish band extending backwards from anterior margin, just proximal to the pterostigma to the encounter of cu-a to base of the Rs & M; 5) tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe; 6) mid leg orange with slightly infused tarsi and hind leg with orange coxa, infuscated trochantellus and the rest black; 7) metasoma with tergite I slightly darker than the color of the mesosoma and getting darker from tergite II towards a dark brown; 8) ovipositor slender, 1.6 × as long as hind tibia.	en	Álvarez-Arellano, Diego, Palacios-Castro, Shirley, Pádua, Diego G.

Coloration. Head black, except apical margin of clypeus slightly yellowish, mouthparts yellowish, except apex of mandible black; antenna dark brown. Mesosoma entirely reddish orange and metasoma with tergite I slightly darker than the color of the mesosoma and getting darker from tergite II towards a dark brown. Anterior leg orange, mid leg orange with slightly infused tarsi and hind leg with orange coxa, infuscated trochantellus and the rest black.

03AE87B3FF95FF9664E9C3F07079FA06.taxon	discussion	Comments. Acrotaphus guacas Álvarez-Arellano, sp. nov. closely resembles A. cuzconus Pádua & Sääksjärvi, 2020 and A. monotaenius Pádua, 2020 mainly by having fore wing blackish with one yellowish band extending backwards from anterior margin, just proximal to the pterostigma to the encounter of cu-a to base of the Rs & M, but differs from it mainly by the mid leg orange with slightly infused tarsi and hind leg with orange coxa, infuscated trochantellus and the rest black, metasoma with tergite I slightly darker than the color of the mesosoma and getting darker from tergite II towards a dark brown (mid leg entirely black and metasoma entirely reddish orange, in A. cuzconus; mid leg entirely orange and metasoma entirely black in A. monotaenius).	en	Álvarez-Arellano, Diego, Palacios-Castro, Shirley, Pádua, Diego G.
