34A05A1F8039590BBC6E4B065C19012B.taxon	diagnosis	Diagnosis. By wing venation pattern (M + m-cu vein partly developed under r-m vein) (Fig. 3 H) Aphidius brethes sp. nov. belongs to subgenus Lysaphidus. Aphidius brethes sp. nov. belongs to Aphidius species group with costulate anterolateral area of petiole like all known Aphidius species in South America (e. g. A. matricariae Hal., A. rhopalosiphi Luzhetzki, A. uzbekistanicus De Stefani-Perez), except for A. ervi Hal. that possesses rugose and A. avenae Hal., A. platensis Brèthes and A. colemani Viereck that have costate anterolateral area of petiole. New species differs from the mostly known Lysaphidus species by having 16 – 17 - segmented antennae (Fig. 3 B), four maxillar palpomeres and two labial palpomeres, while other species have 12 – 14 segmented antennae and usually three maxillar and two or one labial palpomeres (e. g. Aphidius arvensis (Starý), A. erysimi (Starý), A. adelocarinus Smith, A. rosaphidis Smith). Aphidius brethes sp. nov. by 16 – 17 - segmented antennae and four maxillar and two labial palpomeres morphologically resembles A. viaticus (Sedlag) (15, 16 - segmented antennae) and A. ramithyrus Smith (15, 16 - segmented antennae). Moreover, it differs from A. viaticus on having the proportion between length and width of petiole at spiracles level 2.3 – 2.4 × (Fig. 3 F), while A. viaticus possesses 3.0 – 3.5 petiole proportion. The new species differs from A. ramithyrus by shorter flagellomere 1 (proportion between length and width of F 1 is 2.6 – 2.8 × (Fig. 3 C), while in A. ramithyrus it is 3.0 – 3.2 ×) and longer petiole (2.3 – 2.4 × as long as width at spiracles level (Fig. 3 F), while in A. ramithyrus 2.0 – 2.2). Furthermore, Aphidius brethes sp. nov. is mostly yellow colored (Fig. 2), while A. ramithyrus and A. viaticus are darker. Aphidius viaticus parasitizes Pleotrichophorus glandulosus (Kalt.) aphid associated with Artemisia plants, while Aphidius ramithyrus parasitize Capitophorus spp. aphids. We assume that A. brethes sp. nov. parasitizes cereal or soybean aphids.	en	Tomanović, Željko, Kocić, Korana, Belén Forte, Sofía, Nazareno Lentini, Joel, del Pilar Medialdea, María, Noemí Villar, Camila, Bustos, Analí, Gayan-Quijano, Ana Lia, Peris-Felipo, Francisco Javier, Devoto, Mariano (2025): Two new aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) from field crops of South America.

34A05A1F8039590BBC6E4B065C19012B.taxon	etymology	Etymology. The new species takes its name by Juan Brèthes, an Argentine scientist, naturalist, entomologist who has described several aphid parasitoid species.	en	Tomanović, Željko, Kocić, Korana, Belén Forte, Sofía, Nazareno Lentini, Joel, del Pilar Medialdea, María, Noemí Villar, Camila, Bustos, Analí, Gayan-Quijano, Ana Lia, Peris-Felipo, Francisco Javier, Devoto, Mariano (2025): Two new aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) from field crops of South America.

C1ACA7638C9B5D93A59C7B8F3576E5E9.taxon	diagnosis	Diagnosis. The new species is distinguishable from its congeners by combination of characters: apical clawlike bristle and two short setae at the tip of prongs (Fig. 5 G), propodeum carinated with irregular carinae, without central areola (Fig. 5 E) and one to two and two to three longitudinal placodes on flagellomere 1 and 2, respectively (Fig. 5 C). We assume that T. pampas sp. nov. parasitizes cereal aphids. It differs from T. sunnysidensis Fulbright & Pike, 2007, which attack cereal aphids in North America, Europe and New Zealand, by irregular propodeal areola (regular pentagonal in T. sunnysidensis) and by an apical clawlike bristle and two short setae at the tip of prongs (two simple bristles in T. sunnysidensis) (Fulbright et al. 2007). Trioxys pampas sp. nov. shares irregular propodeal areola and clawlike bristle on the top prongs with T. californicus Starý & Zuparko, 1995. However, it easy differentiated from T. californicus by 11 - segmented antennae (T. californicus has 13 - segmented antennae) and almost straight prongs (T. californicus has more curved prongs) (Fulbright et al. 2007). Additionally, T. californicus parasitizes Eucallipterus tiliae (L.) on Tilia cordata (Starý and Zuparko 1995).	en	Tomanović, Željko, Kocić, Korana, Belén Forte, Sofía, Nazareno Lentini, Joel, del Pilar Medialdea, María, Noemí Villar, Camila, Bustos, Analí, Gayan-Quijano, Ana Lia, Peris-Felipo, Francisco Javier, Devoto, Mariano (2025): Two new aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) from field crops of South America.
