A9EC513B51085BBFADC5CD83C586FB30.taxon	diagnosis	Diagnosis. Trissolcus adrianae Costa & Johnson, sp. nov. is a distinctive species which is easily distinguished from other members of the flavipes group by its noticeably depressed habitus; head oblong in anterior view; mandible with only two teeth; frontal depression delimited dorsally by carina; orbital furrow sculptured, constricted through most of its length by lateral expansion of frons; notauli absent; and length of T 2 subequal to length of T 3 – T 6.	en	Costa, Valmir A., Johnson, Norman, Salomão, Adriana, Vasconcellos-Neto, João, Wengrat, Ana, Schoeninger, Karine (2025): A remarkable new species of Trissolcus Ashmead (Hymenoptera, Scelionidae), parasitoid of eggs of Phloea subquadrata (Hemiptera, Phloeidae) in Brazil.

A9EC513B51085BBFADC5CD83C586FB30.taxon	description	Description (female). Body length: 2.18 – 2.44 mm (n = 12). Habitus: distinctly depressed dorsoventrally (Fig. 1). Color. Body: head, mesosoma, and metasoma black. Color of radicle: yellow to dark brown. Color of A 1 – A 6: A 1, A 2 yellow, otherwise brown. Color of A 7 – A 11: brown. Coxae: brownish yellow. Legs beyond coxae: brownish yellow. Head. Claval formula: 1 - 2 - 2 - 2 - 2. Shape of head in anterior view: oblong (Fig. 2), distinctly bulging between antennal insertion and inner orbits. Shape of head in lateral view: strongly protruding anteriorly (Fig. 3). Number of mandibular teeth: two (Fig. 4). Number of clypeal setae: 4. Facial striae: absent. Shape of gena in lateral view: receding posteriorly. Genal carina: absent. Macrosculpture of lateral frons: absent. Microsculpture of lateral frons: punctate, with large, well-defined setigerous punctures irregularly distributed as on vertex, interspaces smooth. Macrosculpture inside antennal scrobe: transversely rugulose. Frontal depression: delimited dorsally by carina (Fig. 2). Orbital furrow: present, constricted through most of its length by lateral expansion of frons (Figs 2, 4). Hyperoccipital carina: weakly developed (Fig. 5). Vertex: angulate, particularly laterally. Preocellar pit: present. Mesosoma. Epomia: absent. Netrion sulcus: complete but obscured by coarse pronotal sculpture. Mesoscutal suprahumeral sulcus: not distinguishable from surrounding surface sculpture. Mesoscutal humeral sulcus: present as a thin groove. Pattern of mesoscutal microsculpture: absent between punctures. Macrosculpture of mesoscutum: punctate, with large, well-defined setigerous punctures irregularly distributed as on vertex. Area bounded by axillar crescent: smooth. Parapsidal signum: absent. Notaulus: absent (Fig. 6). Median mesoscutal line: absent. Median mesoscutal sulcus: absent. Sculpture of mesoscutellum: punctate, with large, well-defined setigerous punctures irregularly distributed as on vertex, interspaces smooth. Postacetabular sulcus: comprised of cells (Fig. 7). Episternal fovea: present. Shape of episternal foveae: elongate with rounded edges. Number of episternal foveae: 3 – 5. Course of episternal foveae ventrally: abutting cells of postacetabular sulcus. Course of episternal foveae dorsally: extending dorsally to mesopleural pit. Sculpture of postacetabular patch: densely punctate. Sculpture of anterior mesepisternum: smooth with punctures. Mesopleural epicoxal sulcus: comprised of cells anteriorly. Mesopleural carina: weakly indicated ventrally. Speculum: transversely striate. Paracoxal sulcus in ventral half of metapleuron: indicated by a line of distinct foveae. Length of intercoxal space: exceeding length of mesocoxae. Anteroventral extension of metapleuron: short and truncated. Line of pits along metapleural carina: present. Setation of metapleuron: absent (Fig. 8). Metapostnotum: invaginated at edges of metascutellum and separating metanotum from propodeum. Metasomal depression of propodeum: with striae radiating from propodeal foramen. Length of postmarginal vein: about 1.8 × as long as stigmal vein. Length of metabasitarsus: longer than combined length of metatarsomeres 2 – 5 (Fig. 9). Metasoma. Sublateral setae on T 1: absent. Setation of laterotergite 1: absent. Sculpture of T 2 posterior to antecostal sulcus: distinctly striate in basal half, striae longer laterally, smooth in apical half. Length of T 3 – T 6: subequal to length of T 2 (Fig. 10). Male. Body length: 1.82 – 2.11 mm (n = 5). Color of antenna: scape and flagellum yellow (Fig. 12).	en	Costa, Valmir A., Johnson, Norman, Salomão, Adriana, Vasconcellos-Neto, João, Wengrat, Ana, Schoeninger, Karine (2025): A remarkable new species of Trissolcus Ashmead (Hymenoptera, Scelionidae), parasitoid of eggs of Phloea subquadrata (Hemiptera, Phloeidae) in Brazil.
