Zagrammosoma americanum Girault

Zagrammosoma americanum Girault (Fig. 4) Zagrammosoma americana Girault, 1916a: 126. Holotype ♀ [examined]. Locality: USA, Colorado, Boulder. Depository: USNM type no. 19642. Zagrammosoma americanum; justified emendation by Peck, 1951: 459. Diagnosis. The most distinguishing character for this species is the transverse, dark stripe across the anterior margin of the mesoscutum that extends from both ends towards, but not reaching the notaulus (Fig. 4D, E). This character is also found in Z. galapagoense, however, the wing patterns are different between the species (Figs 4C versus 18C). Zagrammosoma occidentale has similar color patterns on the body but the mesoscutum lacks the transverse stripe along the anterior margin (Fig. 36D, E). Description. Female - body length 1.11–1.98 mm. Metallic luster on body absent. Scape yellow with black stripe dorsally. Lower face with median stripe absent or present. Vertex with 2 stripes above compound eye. Gena posteriorly with one or two dark stripes below compound eye. Occiput yellow with 2 dark, vertical stripes. Pronotum and mesoscutum with median stripe, either interrupted or complete; laterally with 2 black stripes. Prepectus yellow with dorsal margin dark. Mesoscutellum yellow with three dark stripes. Propodeum yellow with black median carina, anterior margin, and lateral spot. Procoxa and mesocoxa yellow. Metacoxa yellow, sometimes with dark spot basally. Profemur and mesofemur yellow. Metafemur with interrupted or uninterrupted stripe dorsally. Fore wing: basal band absent; cubital band present; parastigmal and stigmal bands present, with perpendicular extension greater than length of stigmal vein; postmarginal band present, with perpendicular extension extending across 75% or more of fore wing width; apical margin hyaline; connection from stigmal band to postmarginal band absent or present. Hind wing hyaline. Gaster completely yellow or yellow with a dark median band and transverse stripes or bands. Upper ocular sulcus present. Pedicel longer than wide. Funiculars symmetrical: first longer than wide (w:l = 0.58–0.86); second longer than wide to wider than long (w:l = 0.7–1.24). Pronotum, in dorsal view, bell-shaped, wider than long (w:l = 1.5–1.93); 3–4 pairs of setae along posterior margin. Mesoscutum reticulate; scattered setae and intermediate setae present. Mesoscutellum wider than long (w:l = 1.13–1.33); submedian grooves present, sometimes faint. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus longer than second tarsomere or subequal (bst:2 nd = 1.0–1.14). Fore wing l:w = 2.25–2.45. Submarginal vein with 5–6 setae dorsally. Basal fold setose. Cubital fold setose. Admarginal setae present. Uncus originating on stigma by more than own length from stigmal apex. Male - as female, except: body length 0.78–1.22 mm; mesoscutum with intermediate setae present or absent; cubital band absent or present; parastigmal band present, with perpendicular extension less than or greater than that of stigmal apex; postmarginal band present, with perpendicular extension greater than that of stigmal apex, but not across 75% or more of fore wing width. Remarks. This is a commonly collected species from the western part of North America (Fig. 5). The infuscation of the cubital line of setae is faint and may be difficult to observe. The width of the postmarginal band is occasionally thinner than the band shown in Fig. 4C but is always present. Gordh (1978) mentions Z. americanum being reared from Asphondylia (Diptera) galls, however the only specimens examined that were reared from this host are Z. occidentale. Hosts. Reared from lepidopteran leaf miners and leaf rollers. Several specimens were reared from hemipteran hosts according to their labels, but these records require substantiation. See Table 3. Hemiptera: Aphididae, Psyllidae. Lepidoptera: Coleophoridae, Elachistidae, Gelechiidae, Gracillariidae, Lyonetiidae. Distribution. Nearctic: Canada (AB, SK), Mexico (CO, GR, EM, OA), USA (CA, CO, ID, NM, DV, TX, UT, WA) (Fig. 5). Additional material examined. CANADA: Alberta: Banff, 51°10’41”N, 115°34’4”W, 13.viii.1949, J. H.
