5F535047F89E2AFD002D8B59F24AA89E.taxon	diagnosis	Diagnosis. Within the New World species of the Trissolcus basalis group, the combination of the broadly rounded vertex, wide gena, and rugose T 2 is found only in T. basalis and T. utahensis. Trissolcus basalis may be distinguished by its coriaceous mesoscutellum, incomplete netrion sulcus and weakly developed episternal foveae. Trissolcus basalis may be dark in color, but typically can be distinguished by the yellow scape (sharply contrasting in color with the dark radicle) and abruptly bicolored antennae.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

BB57DADFF86533EDAD64E9EF764AC28B.taxon	diagnosis	Diagnosis. Trissolcus brochymenae is most similar to T. euschisti and may be distinguished from it by the strongly rugulose ventral portion of the mesepisternum anterior to the mesopleural carina (Figs 44 - 45). This species is also similar to T. euschisti in that it shows a great deal of variability, presumably in association with its wide geographic distribution and host range.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

DB2D934A759E5B7BC4BE86B642B9316F.taxon	diagnosis	Diagnosis. Trissolcus cosmopeplae may be distinguished from other species that have sublateral setae and a narrow gena (T. erugatus, T. hullensis, T. radix, T. solocis, and T. zakotos) by the presence of extensive rugulae on T 2 and the mesoscutellum without macrosculpture. This is also the only New World species outside the Trissolcus thyantae and Trissolcus flavipes groups in which notauli may be visible. All other species with sublateral setae and a narrow gena usually have the posterior region of the mesoscutum longitudinally rugulose and the notauli, if present, are thus obscured.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

819208C7BA6625F9E918FB5597C3AEC3.taxon	diagnosis	Diagnosis. Trissolcus cultratus is easily distinguished from other members of the Trissolcus flavipes group treated here by the parallel arched rugae on the frons between the anterior ocellus and the antennal scrobe. This species also lacks a well-developed orbital furrow near the malar sulcus, and by this character it may be separated from T. brochymenae, T. edessae, T. euschisti, and T. japonicus.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

FF34959BDCB188D2A2CC67EE41261908.taxon	diagnosis	Diagnosis. Trissolcus edessae may be distinguished from the native species of Nearctic Trissolcus in the Trissolcus flavipes group (T. brochymenae, T. euschisti, and T. strabus) by the abruptly bicolored female antennae. It may be separated from T. japonicus by the presence of 2 clypeal setae and the episternal foveae that do not form a continuous line from the postacetabular sulcus to the mesopleural pit. It may be separated from T. cultratus by the absence of parallel arched rugae on the frons. In T. edessae a median mesoscutal carina is often present, and this is absent in T. cultratus and T. japonicus. Johnson (1984) used the absence of a mesopleural carina in T. edessae as a diagnostic character. Our examination included a specimen in which the mesopleural carina is present (Fig. 58) and thus we prefer not to use this character for identification. A result of this is that unambiguous identification of male specimens may require movement or removal of the wings to properly evaluate the surface sculpture within the axillar crescent.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

2AB1BDDBD59DB2543CFC17A9ECFE0E01.taxon	diagnosis	Diagnosis. Trissolcus erugatus may be distinguished from the most common Southwestern species of Trissolcus discussed here, T. utahensis, by its strongly narrowed gena, angulate vertex, and the lack of rugulae on T 2 (occasionally rugulae are present, but these are very short in comparison with those of T. utahensis). It may be distinguished from T. hullensis by the following characters: metapostnotum invaginated near metascutellum and separating metanotum from propodeum, anterior extension of metapleuron short, not reaching mesocoxa, mandibular teeth shallowly incised; mesopleural carina absent; legs and A 1 - A 6 usually yellow. Trissolcus cosmopeplae may usually be separated from T. erugatus by the strong development of rugulae on T 2 and the long anteroventral extension of the metapleuron toward the mesocoxa in the former species. Trissolcus erugatus seems to be a rather isolated species within the New World fauna of the genus. The narrowed gena allies it with T. hullensis, T. solocis, T. radix, and T. cosmopeplae, but the condition of the metapostnotum, mandibular teeth, and metapleural extension usually distinguish it quite clearly. Specimens from the Southwest are easily identifiable, but variation in color and sculpture in the northern part of its range may result in confusion between this species and T. cosmopeplae.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

F36B3F2492098CB908069FC375E196D0.taxon	diagnosis	Diagnosis. Trissolcus euschisti may be distinguished from the similar T. brochymenae by the smooth or shallowly impressed sculpture on the ventral portion of the mesopleuron anterior to the mesopleural carina. The smaller specimens of T. euschisti are often quite distinct from the larger ones in the following characters: number of lateral setae on T 1, extent of fine wrinkles on T 2, extent of rugae on S 2, extent of S 1 setation, number of setae on the mesopleuron above the mesocoxa, sculpture of the upper portion of the frons, extent of transverse striae within the antennal scrobe, and the presence of a shallow groove below the anterior ocellus. The separation of T. euschisti and T. brochymenae may be difficult with specimens that exhibit an intermediate state of faint rugosity on the anteroventral mesopleuron. These specimens are not common in our experience and the situation reflects the need for molecular data to further test the hypotheses of species delimitation presented here and in the revisions of Nearctic Trissolcus by Johnson (1984, 1985 a, b).	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

Trissolcus hullensis may be distinguished from these by the anteriorly invaginated metapostnotum. Additional characters useful for identification are: the paracoxal sulcus in the ventral half of the metapleuron, absent in T. hullensis, present in T. radix and T. zakotos; sculpture of the mesoscutellum, coriaceous or smooth in southern specimens of T. hullensis, coarsely areolate in T. solocis and T. radix; the color of the radicle, black in T. hullensis, T. zakotos and T. solocis, yellow in T. radix; and the rounded vertex, sharply angled in T. radix and T. solocis.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

As previous authors have stated (Yang et al. 2009), T. japonicus belongs to the Trissolcus flavipes species group, first recognized by Kozlov and Le (1976) and refined by Johnson (1984). Trissolcus japonicus may be separated from other species of the Trissolcus flavipes group Trissolcus in the Nearctic by the following characters: orbital furrow expanded near intersection with malar sulcus; postacetabular and mesopleural epicoxal sulci formed by lines of closed cells (Fig. 70); episternal foveae extending from dorsal apex of postacetabular carina to mesopleural pit (Fig. 68); 4 clypeal setae (Fig. 25).	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

Trissolcus strabus may be distinguished from species of the Trissolcus flavipes group in the Nearctic by the ventral constriction of the orbital furrow and the relatively coarse sculpture of the mesoscutellum. Most specimens have setae present on the first laterotergite, a character found among some Trissolcus flavipes group species of the Neotropics, but not elsewhere in the Nearctic. The rugose mesoscutellum can be used as a diagnostic character in most cases, but the degree of rugosity is variable. In some specimens the mesoscutellum is almost completely smooth with faint hints of rugae along the anterior margin. In others, the rugosity is confined to the lateral portions of the sclerite. In the latter case, rugose sculpture exists where there is setation, and in specimens with an entirely rugose mesoscutellum, the entire surface is setose. This leads us to hypothesize that, at least on the mesoscutellum of T. strabus, the rugose sculpture and setation are linked. The specimens with reduced macrosculpture on the mesoscutellum also have reduced sculpture on the lateral mesoscutum (lateral of the notaulus), revealing coriaceous microsculpture.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

7FF4CDA3D2AE5BCA872BA4A2FCFF41DC.taxon	diagnosis	Diagnosis. Trissolcus utahensis is a relatively dark-colored species, though some specimens from the southern part of its range have lighter-colored appendages. In the Nearctic region it is most similar to T. basalis. The two may be distinguished by the color of A 1, usually dark, concolorous with the radicle in T. utahensis, and yellow, sharply contrasting with the dark radicle in T. basalis; and the mesoscutellar sculpture, smooth in T. utahensis, coriaceous in T. basalis.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).

9E31243F63380E3661E67FA878278E1A.taxon	diagnosis	Diagnosis. Trissolcus zakotos is closest to T. radix, with which it shares a well defined paracoxal sulcus. The two may be separated by the presence of of bright yellow radicle and coarse sculpture of the mesoscutellum in T. radix. In T. zakotos the radicle is brown and the mesoscutellum is covered by microsculpture, but without additional rugae. Additionally, T. zakotos has numerous (3 - 5) rugae radiating from the lateral edge of the clypeus. This character is present is both T. radix and T. solocis but is less pronounced and the number of rugae is smaller (1 - 2). Etymology. The epithet " zakotos " is Greek for " angry " and is applied to this species because of the appearance of its frons. The name is treated as an appositional noun.	en	Talamas, Elijah J., Johnson, Norman F., Buffington, Matthew (2015): Key to Nearctic species of Trissolcus Ashmead (Hymenoptera, Scelionidae), natural enemies of native and invasive stink bugs (Hemiptera, Pentatomidae).
