AD71792FFF8B2718FD82AA207B95FB19.taxon	diagnosis	Diagnosis Face smooth, aciculate or granulate. Subocular sulcus usually distinct. Clypeus from flat to weakly convex, distinctly separated to almost completely fused with face, its lower edge straight or truncate, thus labrum always visible. Axis of mandible strongly twisted; lower tooth small and hardly visible or completely reduced. Temples very short and strongly narrowed behind eyes to buccate in dorsal view. Mesoscutum densely, but sometimes partly (only anteriorly) pubescent; notauli usually absent. Scutellum basally from arched to straight. Epicnemial carina always present but sometimes short. Pleural carina usually complete but sometimes partly or entirely reduced. Propodeum distinctly carinated (lateromedian longitudinal and apical transverse carinae present) or almost completely lacking carinae. Fore wing with vein 3 rs-m present or absent; hind wing with nervellus not intercepted or intercepted. First metasomal tergite from almost entirely smooth to granulate, rugulose or longitudinally wrinkled; latero-median longitudinal carinae from developed to almost entirely absent; lateral oblique grooves usually present, weak to deep. Second tergite weakly sculptured only basally to distinctly sculptured almost to apex. Ovipositor sheath from about 0.4 × to 0.9 × as long as hind tibia, basal part usually flexible, apical part widened and pubescent.	en	Varga, Oleksandr (2024): Review of the genus Stenomacrus Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) from Kenya and Burundi: a first step to understanding the diversity of the genus in the Afrotropics.

AD71792FFF8A271FFD91ACAD7804F951.taxon	diagnosis	Diagnosis Stenomacrus clypeatus sp. nov. is characterized by the combination of the following: face aciculate; clypeus relatively convex, distinctly separated from face, yellow (Fig. 2 A); antenna with 27 flagellomeres, first flagellomere 3.5 × as long as wide; temples 0.6 × maximum diameter of eye in dorsal view, strongly narrowed (Fig. 2 D); propodeum smooth, with only lateral longitudinal carina present apically (Fig. 2 F); fore wing with vein 2 rs-m about 0.7 × the distance between 2 rs-m and 2 m-cu; vein 3 rs-m absent; hind wing with nervellus vertical (Fig. 2 E); first tergite 2.3 × as long as its apical width, longitudinally wrinkled; second tergite 1.6 × as long as its apical width, distinctly longitudinally wrinkled on basal 0.7 (Fig. 2 F); ovipositor sheath about 0.6 × as long as hind tibia (Fig. 2 A). Stenomacrus clypeatus sp. nov. differs from all known Afrotropical species in the elongate and strongly wrinkled metasomal tergites 1 – 2 in combination with a convex clypeus. The shape of the clypeus indicates that this species potentially belongs to the genus Chilocyrtus, but the mandibles are closed and thus it is not possible to acertain the presence / absence or the shape of the lower tooth.	en	Varga, Oleksandr (2024): Review of the genus Stenomacrus Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) from Kenya and Burundi: a first step to understanding the diversity of the genus in the Afrotropics.

Stenomacrus valvator sp. nov. differs from all known Afrotropical species in having a long and upcurved ovipositor and strongly sculptured metasomal tergites 1 – 2. The species also exhibits a unique character never found in the genus Stenomacrus before: absence (or at least very strong reduction) of the inner mandibular tooth which is the only feature used in defining the genus Chilocyrtus. This supports the assumption of the future synonymy of these two genera.	en	Varga, Oleksandr (2024): Review of the genus Stenomacrus Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) from Kenya and Burundi: a first step to understanding the diversity of the genus in the Afrotropics.

AD71792FFF9C270DFD9AA96B7871FC59.taxon	diagnosis	Diagnosis Stenomacrus vuriaensis sp. nov. is characterized by the combination of the following: face weakly granulate (Fig. 9 B); antenna with 20 – 21 flagellomeres, first flagellomere 2.9 – 3.3 × as long as wide; temples 0.4 × the maximum diameter of eye in dorsal view, strongly narrowed (Fig. 9 D); propodeum weakly granulate apically, with area apicalis narrowly interrupted centrally (Fig. 9 D); fore wing with vein 2 rs-m about 0.9 × the distance between 2 rs-m and 2 m-cu; vein 3 rs-m absent (Fig. 9 E); first tergite 1.8 – 2.0 × as long as its apical width, granulate, with latero-median longitudinal carinae indistinct; second tergite about 1.4 – 1.6 × as long as its apical width, with only traces of granulation on basal 0.2 of the tergite (Fig. 9 F); ovipositor sheath about 0.6 × as long as hind tibia (Fig. 9 A). Stenomacrus vuriaensis sp. nov. is similar to S. pronotalis sp. nov. but differs in the longer and more strongly sculptured first metasomal tergite, 1.9 – 2.0 × as long as its apical width (1.4 × in S. pronotalis), and darker pronotum, with at most some yellow marks distally (distinctly paler than the rest of the mesosoma in S. pronotalis).	en	Varga, Oleksandr (2024): Review of the genus Stenomacrus Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) from Kenya and Burundi: a first step to understanding the diversity of the genus in the Afrotropics.
