This species runs into <i>D. jilinensis</i> Chen and Song (2004) [this species is synonymized with <i>D. purda</i> (Papp, 1977) by Liu <i>et al</i>. (2018)] as per the key by Chen and Song (2004), nevertheless, it differs from <i>D. fernandeztrianai</i> <b>sp. nov.</b> as follows: in <i>D. fernandeztrianai</i> <b>sp. nov.</b> 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 <i>D. purda,</i> 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 <i>et al</i>. (2018) to <i>D. poliobrevis</i> Liu &amp; Chen, 2018, however, it differs from <i>D. fernandeztrianai</i> <b>sp. nov.</b> as follows: in <i>D. fernandeztrianai</i> <b>sp. nov.</b> 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 <i>D. poliobrevis</i> T1 parallel-sided and as long as posterior width, pterostigma brown, ovipositor sheath nearly as long as metatibia). <i>Dolichogenidea fernandeztrianai</i> <b>sp. nov.</b> is similar to <i>Dolichogenidea eleagnellae</i> Tobias, 1976, but it differs from <i>D. eleagnellae</i> as follows: in <i>D. fernandeztrianai</i> <b>sp. nov.</b> 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 <i>eleagnellae</i> 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). <b>Paratypes:</b> 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. <b>Etymology:</b> 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.
