Main background colour black and reddish-yellow (Fig. 1 A). Head short, its width 3.6 × its length, temples about 0.5 × transverse width of eye, sparsely setose, abruptly narrowed behind eyes (Fig. 2 B). Antenna short, 0.7 × length of fore wing, with flagellum finely setose, with 34 flagellomeres, basal flagellomere transverse, oblique apically, median flagellomeres almost as long as broad, subapical transverse (Fig. 1 A). Face 2.2 × times as wide as high, coarsely reticulated, sparsely setose, with distinctly raised curved carina on edge of epistoma, edge of antennal socket raised and produced as carina between antennal socket and inner margin of eye that curves downwards (Fig. 2 A). Clypeus almond-shaped, sparsely punctate with rough punctures dorsally, and impunctate ventrally. Mandible distinctly punctate, upper tooth slightly shorter than lower tooth (Fig. 2 A). Malar space 0.8 × times basal width of mandible. POL = 1.6 times of Od, OOL = 2.8 times of Od. Mesosoma coarsely and sparsely punctate with rough punctures, setose (Figs 2 C, D). Pronotum striate and sparsely punctate with rough punctures (Fig. 2 C). Scutum roughly punctate, flat (Fig. 2 D). Scutellum roughly punctate, flat, heavily setose (Fig. 2 D). Speculum large, impunctate, shiny, slightly striate anterodorsally (Fig. 2 C). Metapleuron with finer punctures. Legs stout, compressed, hind femur 4.3 × as long as wide in its middle. Tarsal claws pectinate with high teeth slightly inclined medially (Fig. 3 E). Propodeum short, heavily setose, area superomedia transverse, area petiolaris elongate (Fig. 2 H). Propodeal spiracle elongate, 2 × as long as wide, slightly closer to pleural carina than to lateral carina, connected to latter by ridge. Lateral longitudinal and posterior transverse carina forming small tooth where they meet. Area petiolaris longer than area superomedia, latter pentagonal, area basalis absent. Fore wing with pterostigma elongate, 3.6 × as long as broad (Fig. 3 A). Distal abscissa of M complete to wing margin, between rs-m and 2 m-cu longer than rs-m. Hind wing with distal abscissae of Rs, M, Cu 1 and 1 A distinct, Cu & cu-a is sharply broken (Fig. 3 A). Wing membrane with dense short setae (Fig. 3 A). Fore wing with cu-a postfurcal. Vein 2 m-cu with single bulla. Metasoma setose (Fig. 1 A). T 1 – 2 finely and sparsely punctate, T 3 – 6 without punctures. T 1 2.4 × as long as apically broad (Fig. 2 F). T 1 with lateromedian carina defined, reaching spiracle, ventral carina distinct, with slight striation behind glymma (Fig. 2 F). Ovipositor 1.8 × as long as hind tibia (Fig. 1 A). Coloration (Figs 1 A, 2, 3). Body black, following structures yellow: face, scape and pedicel, basal part of clypeus, malar space, pronotum dorsally, inner part of fore femur, fore tibia and tarsus, distal part of middle femur, middle tibia, proximal parts of middle tarsomeres 1 – 3, distal tip of hind femur, hind tibia except for its distal tip, tegula, auxillar sclerite, proximal part of T 1, most of membranous part of S 1, distal part of S 2 – 3; following structures yellow-white: distal part of fore coxa and fore trochanter completely, middle coxa and trochanter; following structures reddish-yellow: hind femur except for its distal part, most of T 1 except for its proximal part, T 2 – 3 and T 4 basally. Wing membrane infumate except proximally (Figs 1 A, 3 A). Male.

03A63B1FA01E4C58C893E845FA37E72F.taxon	etymology	Etymology. The specific name is feminine adjective, derived from Darwin wasp genus name Brachyscleroma Cushman, 1940 of the subfamily Sisyrostolinae Seyrig, 1932, whose habitus resembles the described species, and the Greek morpha (μορφή, appearance).	en	Reshchikov, Alexey (2025): Bylesia gen. nov., a new genus of Darwin wasp (Hymenoptera: Ichneumonidae) from the Eastern Himalaya.
