Transverse diameter of eye (dorsal view) 1.25–1.55× longer than temple. Wings distinctly brownish darkened............... Bracon subcylindricus Wesmael Remark. The key is based on examination of the type material of all listed species. Bracon subcylindricus is considered here to be a valid species despite the recent synonymisation with B. longicollis Wesmael (Papp, 2012). Two latter species clearly differ by the shape of tarsal claws.Published as part of Samartsev, Konstantin G., 2018, New species of the subfamily Braconinae (Hymenoptera: Braconidae) from the Russian Far East, pp. 238-254 in Zootaxa 4388 (2) on pages 245-249, DOI: 10.11646/zootaxa.4388.2.6, http://zenodo.org/record/118733

Antenna mainly brown, five basal segments yellow. Palpi yellow. Legs yellow. Wings faintly infuscate. Pterostigma brown, pale yellow to subhyaline in basal third. Male. Propodeum more coarsely rugulose, with carinae sometimes almost hided by surrounding sculpture. Body sometimes darker. Otherwise very similar to female except sexual features. Comparative diagnosis. This new species is similar to Leiophron (L.) apicalis Haliday, 1833, but differs in having the occipital carina complete dorsally (widely interrupted in P. apicalis), antenna only 13-segmented (always more than 13-segmented in P. apicalis), basal flagellar segment shorter, 2.5 × longer than wide (longer, 3.7–4.0 × longer than wide in P. apicalis), mesoscutum mostly with dense and rather long setae (almost glabrous in P. apicalis), first metasomal tergite wide and more or less linearly striate (narrow and rugose in P. apicalis). Etymology. This species is named from Latin “pubis” (pubescent) and “scutum” (shield) because the mesoscutum is distinctly pubescent.Published as part of Ku, Deok-Seo, Samartsev, Konstantin G. & Belokobylskij, Sergey A., 2020, New species of Euphorinae parasitoids of the family Braconidae (Hymenoptera) from South Korea, pp. 256-270 in Zootaxa 4742 (2) on pages 260-263, DOI: 10.11646/zootaxa.4742.2.2, http://zenodo.org/record/367778
