Paratypes: 2 females, same data as Holotype (TMUC). Diagnosis The newly described species can be distinguished from all previously described species of the genus Dolichogenidea from the Palaearctic region by the following combination of characters: Antennal flagellomeres, all coxae and metafemur dark brown to black; tegula reddish yellow or yellow; pterostigma whitish yellow with brownish margin; propodeum with areola weakly defined by an impression; fore wing vein R 1 as long as or slightly longer than pterostigma; vein R 1 4.90× as long as distance of vein R 1 to vein 3RSb (Figure 3- A); T 1 more or less parallel- to subparallelsided i.e., slightly narrower medially; T1 smooth, with a distinct protuberance on central area; T1 length 1.70× posterior width; T2 smooth, transverse and rectangular; T 3 longer than T2 (Figure 2- F); hypopygium pointed apically and slightly protruding beyond apical tergites; ovipositor sheath with uniform width from base to apex and clearly longer than metatibia (Figure 2- E). Description (Female-Holotype) Body Length without Ovipositor: 2.50 mm, antennae length 2.60 mm and forewing length 2.60 mm Head: Antenna about as long as body; F 2, 3, 14, 15 length/width: 2.40, 2.40, 1.30 and 1.30, respectively; mouthparts not elongated (Figures 2-A and -B); head rounded or weakly constricted behind eyes (Figure 2- C); upper face (frons) smooth to rather finely punctate; gena, vertex and lower face (face) distinctly punctate; basal width of mandible 3.20–4.00× malar space length (Figure 2-A); OOL, OD, POL length: 0.13, 0.06 and 0.13 mm, respectively (Figure 2- C). Mesosoma: Anteromesoscutum densely punctate and setose, notauli indistinct; scutoscutellar suture narrow, distinctly crenulate; mesoscutellar disc finely and sparsely punctate to smooth and shiny; metanotum with uniform coarse wrinkles; anterior half of propodeum with few punctures and shiny, rest mostly smooth to slightly uneven; propodeum without distinct areola, weakly defined by an impression; pronotum weakly punctate; propleuron punctate; prepectal carina absent; mesopleuron medially smooth with some punctures on antero- and ventro-lateral parts; metapleuron weakly wrinkle to smooth, anteriodorsal corner rugulose, and with deep medial pit on anterior half (Figure 2-D). Wings: Forewing length 2.60 mm; Forewing length/width: 2.90; vein R1 as long as or slightly longer than pterostigma; Pterostigma length/width: 2.50; vein R1 4.90× as long as distance of vein R1 to vein 3RSb; vein r as long as or slightly longer than vein 2RS; vein 1-CUb slightly shorter than vein 1-CUa (Figure 3-A). Legs: Metafemur length/width: 3.60; length of metafemur, metatibial, metabasitarsus and sum of other metatarsal segments i.e., sum of segments 2, 3, 4 and 5: 0.75, 0.85, 0.40 and 0.60 mm, respectively; length of metatibial inner and outer spur 0.20 and 0.17 mm, respectively; metatibia inner spur length/metabasitarsus length: 0.50. Metasoma: T1 more or less parallel- to subparallel-sided i.e. slightly narrower medially; T1 smooth, with a distinct central protuberance; T1 length 1.70× posterior width; T2 smooth, transverse and rectangular (T2 posterior width 2.75× its medial length); T3 longer than T2 (T3/T2 length: 1.25) (Figure 2-F); hypopygium pointed apically, slightly extending beyond the apex of metasoma; ovipositor sheath with uniform width and slightly curved downwards; ovipositor sheath clearly longer than metatibia (ovipositor sheath 1.20× as long as metatibia), ovipositor sheath length 1.15 mm (Figure 2-E). Colouration: Body black; except yellow or reddish yellow mouthparts, tegula, fore legs, apex of mesofemur, mesotibia, mesotarsus, basal one-third of metatibia and ovipositor; metatarsus brown; palpi whitish yellow; pterostigma whitish yellow, with brownish margin; wing venation with combination of whitish yellow and brown (Figures 2 and 3). Male: Unknown. Note: Although there is no available key that covers all Palaearctic species of Dolichogenidea, we provide comparisons of Dolichogenidea fernandeztrianai sp. nov. with all previous keys of Palaearctic Dolichogenidea. Dolichogenidea fernandeztrianai sp. nov. runs close to D. britannica (Wilkinson, 1941), in the keys by Nixon (1972) but it differs from the latter as follows: in D. fernandeztrianai sp. nov. T1 more or less parallel- to subparallel-sided not narrowed apically and ovipositor sheath 1.20× as long as metatibia (whereas in D. britannicus T1 markedly narrowed towards apex and ovipositor sheath twice as long as metatibia). This species runs into D. jilinensis Chen and Song (2004) [this species is synonymized with D. purda (Papp, 1977) by Liu et al. (2018)] as per the key by Chen and Song (2004), nevertheless, it differs from D. fernandeztrianai sp. nov. as follows: in D. fernandeztrianai sp. nov. T1 length 1.70× posterior width; pterostigma whitish yellow, with brownish margin; anterior half of propodeum with some punctures, shiny, other areas mostly smooth to slightly uneven, propodeum without distinct areola, weakly defined by an impression; notauli not defined (whereas in D. purda, T1 1.50× its posterior width, pterostigma evenly brown; propodeum mostly smooth, with only a small trace of posterior areola carinae near nucha, notauli distinct by crowded punctation). This species runs in the key by Liu et al. (2018) to D. poliobrevis Liu & Chen, 2018, however, it differs from D. fernandeztrianai sp. nov. as follows: in D. fernandeztrianai sp. nov. T1 more or less parallel- to subparallel-sided i.e., slightly narrowermedially, T1 length 1.70× posterior width; pterostigma whitish yellow, with brownish margin; ovipositor sheath 1.20× as long as metatibia (whereas in D. poliobrevis T1 parallel-sided and as long as posterior width, pterostigma brown, ovipositor sheath nearly as long as metatibia). Dolichogenidea fernandeztrianai sp. nov. is similar to Dolichogenidea eleagnellae Tobias, 1976, but it differs from D. eleagnellae as follows: in D. fernandeztrianai sp. nov. scutoscutellar suture narrowed with 20 crenulate; ovipositor sheath clearly longer than metatibia, 1.20× as long as metatibia; pterostigma whitish yellow, with brownish margin (whereas in eleagnellae scutoscutellar suture wide and deep with 10 crenulate; ovipositor sheath slightly longer than metatibia; pterostigma entirely dark i.e. opaque brown to blackish brown, without pale basal spot). Paratypes: F 2, 3, 14, 15 length/width: 2.40–2.70, 2.40–2.70, 1.16–1.30 and 1.20– 1.25, respectively; OOL,OD,POL length: 0.12, 0.05–0.06 and 0.13–0.15 mm, respectively; Forewing length: 2.70–2.75 mm; Forewing length/width: 2.90–3.00; Pterostigma length/width: 2.60–2.70; length of metafemur, metatibial, metabasitarsus and sum of other metatarsal segments: 071–0.75, 0.83–0.92, 0.41–0.42 and 0.60 mm, respectively. Etymology: The new species is named in the honor of Dr. Jose L. Fernandez-Triana, specialist on the systematics of Braconidae at the Canadian National Collection of Insects, for his significant contributions to the Microgastrinae knowledge of the world.
