Zagrammosoma Ashmead Hippocephalus Ashmead, 1888: 7. Type species: Hippocephalus multilineatus Ashmead; by monotypy. Zagrammosoma Ashmead, 1904: 354. Replacement name for Hippocephalus Ashmead, preoccupied by Hippocephalus Swainson, 1839, later recognized as a junior synonym of Percis Scopoli, 1777 (Scorpaeniformes: Agonidae). Zagrammatosoma Schulz, 1906: 142. Unjustified emendation. Corrected by Bouček, 1959: 172. Mirzagrammosoma Girault, 1915: 279. Type species Mirzagrammosoma lineaticeps Girault; by monotypy. Synonymy by La-Salle, 1989: 232. Diagnosis. Based on the present analysis, Zagrammosoma is characterized by a combination of 3 characters: vaulted vertex that extends above the compound eyes (Fig. 1A), notaulus curving to meet the axilla and never reaching or approaching the posterior margin of the mesoscutum (Fig. 1F), and median carina on the propodeum present (Fig. 1F). Species that are mostly yellow in color generally have dark lines between sclerites, especially along the notaulus, axilla, mesoscutellum, and prepectus. Within Cirrospilini, Zagrammosoma is most similar, in terms of morphology and color patterns, to Cirrospilus and Burkseus; however, these 2 genera both possess a notaulus that is complete and extends to the posterior margin of the mesoscutum (Fig. 1D, G). Burkseus and some species of Cirrospilus (C. ambiguus, C. margiscutellum, C. sp. 4154, C. sp. D4977) also lack a median carina on the propodeum (Fig. 1G). Pseudiglyphus Girault have a notaulus that curves to meet the axilla, but lack a vaulted vertex, and are drab brown in coloration, with hyaline wings. Description. Body length: female 0.75���2.9 mm; male 0.63���1.62 mm. Overall body coloration variable: mainly yellow heads and bodies, with varying degrees of dark lines and bands present, or mainly dark heads and bodies, with yellow markings either on the head or dorsal side of mesosoma. Metallic body coloration absent, except in Zagrammosoma metallicum n. sp. Lower face (lof) with dark, median stripe absent (Figs 8A, 23A) or present (Fig. 1A). Occiput yellow with dark, vertical stripes or bands present or absent. Pronotum and mesoscutum dorsally variable: completely yellow (Fig. 45D, E), completely dark (Fig. 21D), with interrupted median line (Fig. 1E, F), or with uninterrupted median line (Figs 10D, 12D, 23D). Fore wing with or without dark patterns on wing disc. Dark coloration at junctions between parastigmal vein and marginal vein, and between marginal vein and postmarginal vein always present. Hind wing hyaline, rarely with infuscation along apical margin. Procoxa, mesocoxa, and metacoxa color variable: all yellow, basally dark, or completely dark. Profemur yellow. Mesofemur usually all yellow, rarely dark basally. Metafemur coloration variable: all yellow (Fig. 36B), yellow with an uninterrupted dark stripe on dorsal margin curving posterolaterally on outside of femur (Fig. 18B), yellow with interrupted dark stripe - resulting in a ���spot��� on outside of femur (Fig 4B, 30B), with a wide dark band encircling femur (Fig. 16B), or completely dark (Fig. 28B).

Anterior ocellus (ao) positioned on occiput adjacent to apex of vertex (Fig. 1I); posterior ocelli (po) positioned lower on occiput (Fig. 1I) (in dried specimens, the vertex will sometimes collapse, making the anterior ocellus appear at the vertex, or on frons). Vertex with scattered, short setae present (Fig. 1A); paired large setae absent. Occipital carina absent. Antenna: dorsal margin of torulus above lower margin of compound eye. Scape and pedicel setose; scape not extending to vertex; pedicel length variable, longer than wide or subequal. Pedicel lacking carinae. Funiculars with linear sensilla. Two funiculars (fu), always cylindrical, with variable width to length ratio. Clava (clv) longer than wide, consisting of three clavomeres (Fig. 1I). Body: pronotum (no 1 ) shape variable. Pronotal collar carina absent; bristle-like seta laterally. Propleura separated posteriorly, exposing a visible prodiscriminal groove (Fig. 1I). Midlobe of mesoscutum (msc) sculpturing evenly reticulate (Fig. 1F) or linearly reticulate (Fig. 48 D���F); one pair of bristle-like setae present posterolaterally, originating posteriorly to anterior margin of axilla (Fig. 1E). Lateral lobe of mesoscutum with one bristle-like seta and small, scattered setae. Notaulus (not) complete and curved to meet anterior margin of axilla (axl) (Fig. 1F). Axilla advanced, more than 75% of longitudinal length, beyond posterior margin of mesoscutum (Fig. 1F).

Hind basitarsus length variable: shorter than 2 nd tarsomere, subequal, or longer than 2 nd tarsomere. Fore wing: Submarginal vein smoothly joining parastigmal; 3���9 setae dorsally. Costal cell setose. Admarginal setae (ams) present in one (Fig. 1H), or, rarely, two rows. Uncus (unc) position variable: originating on stigma by less than, more than, or its own length from stigmal apex (Fig. 1H). Postmarginal vein present. Basal fold setose, sometimes with only one or two setae. Cubital fold setose, with setal line complete to basal vein or absent anteriorly. Hosts. Zagrammosoma parasitizes leaf miners and leaf rollers in Diptera, Coleoptera, Hymenoptera, and Lepidoptera (Table 3). Gordh (1978) states that Zagrammosoma has been recovered as a hyperparasite of hymenopteran leaf-miner parasitoids; however, he was referring to Z. nigrolineatum as the hyperparasitic species, which is now a synonym of Burkseus vittatus (Perry & Heraty, 2019). Nystrom & Evans (1989) and Digweed (1998) record Z. multilineatum and Z. sp., respectively, emerging from hymenopteran Birch leafminers (Tenthredinidae). While it is difficult to determine the actual species recovered without direct examination of the specimens, it is accurate to record Zagrammosoma as a parasitoid of hymenopteran leaf miners. One examined specimen of Z. multilineatum was reared from the sawfly Metallus sp. (Tentredinidae) (see species description). There are several individual host records of Z. americanum emerging from Hemiptera (Table 3), but more evidence is needed to prove this concretely. This could be Zagrammosoma emerging in bulk samples of hemipterans, which may have contained concealed or unnoticed leaf miners in the collected plant material. If this is true, these individuals may be acting as hyperparasitoids, as Zagrammosoma has not previously been recorded parasitizing non-holometabolous insects. Zagrammosoma has been reared from a large number of agricultural crops, including alfalfa, apple, citrus, coffee, cotton, corn, jojoba, muscadine, potato, and tomato, as well as plants grown for ornamental and timber purposes, including aspen, oak, poplar, pine, and willow. Table 3 presents a full list of host and host plants by species based on the material examined and publications with unambiguously identifiable species of Zagrammosoma. Distribution. The majority of Zagrammosoma species are found in the Nearctic, with only a few species found in each of the remaining ecozones: Afrotropical (1), Australasian (1), Indo-Malay (2), Nearctic (16), Neotropical (9), Oceania (1), and Palearctic (1) (number of species in each ecozone noted in parentheses). Five of the 9 species found in the Neotropical region (Z. lineaticeps, Z. multilineatum, Z. occidentale, Z. trifurcatum, Z. villosum) are also found in the Nearctic, while Z. flavolineatum is found in both Oceania (Hawaii) and the Nearctic. Coupled with the results from the ML analysis (Fig. 2), this may suggest origins of Zagrammosoma outside the Nearctic or Neotropic, with rapid diversification and speciation occurring after introduction into the New World. Etymology. The original designation for the genus, Hippocephalus, means ���horse head��� and accurately describes the shape of the head in lateral view. Ashmead (1904) did not specify why he named Zagrammosoma as he did, but it translates from Greek to mean ���body with a lot of writing.��� This is appropriate to describe a group of ���tattooed wasps,��� the official common name for Zagrammosoma, approved by the Entomological Society of America, April 2019 (https://www.entsoc.org/sites/default/files/files/common_name.pdf). As Zagrammosoma is neuter, adjectival species names must also be neuter in gender. Key to species of Zagrammosoma 1.
