Zagrammosoma interlineatum Girault   stat. rev.

( Fig. 23 View FIGURE 23 )

Zagrammosoma interlineata Girault, 1916a: 125–126   . Holotype ♀ [examined]. Locality: USA, Washington D.C., 6.x.1880. Type depository: USNM type no. 19641 - UCRCENT471659.

Zagrammosoma interlineatum   ; justified emendation by Peck, 1951: 459.

Cirrospilus interlineatus   ; unjustified combination and spelling by Herting 1975: 28.

Diagnosis. Specimens of Z. interlineatum   have usually been identified as Z. americanum   and Z. multilineatum   , as the differences between the species are slight. Zagrammosoma interlineatum   lacks any dark coloration between the notaulus and anterior margin of the mesoscutum ( Fig. 23D, E View FIGURE 23 ), unlike both Z. americanum   ( Fig. 4D, E View FIGURE 4 ) and Z. multilineatum   ( Fig. 34D, E View FIGURE 34 ). Zagrammosoma americanum   also possesses a dark, transverse stripe underneath the posterior margin of the pronotum. The fore wing of Z. interlineatum   has a subcircular dark patch posterior to the stigmal vein ( Fig. 23C View FIGURE 23 ), and the pattern in Z. multilineatum   resembles a “w” in shape ( Fig. 34C View FIGURE 34 ). A median stripe on the lower face is present in Z. multilineatum   and absent in Z. interlineatum   .

Description. Female - body length 1.8–2.02 mm. Metallic luster on body absent. Scape yellow with black stripe dorsally. Lower face with median stripe absent. Vertex with 2 stripes above compound eye. Gena posteriorly with dark stripes below compound eye. Occiput yellow with 2 dark, vertical stripes. Pronotum with median strip complete; laterally with 2 dark stripes. Prepectus yellow with dark stripe along dorsal margin. Mesoscutum with median stripe complete. Mesoscutellum yellow with three dark stripes. Propodeum yellow with black median carina, anterior and posterior margins, diagonal line connecting anterior and posterior margins. Procoxa and mesocoxa yellow. Metacoxa yellow with black stripe basally. Profemur and mesofemur yellow. Metafemur yellow with interrupted stripe dorsally. Fore wing: basal and cubital bands absent; parastigmal band present, with perpendicular extension less than or equal to that of stigmal apex; stigmal band present, with perpendicular extension greater than that of the stigmal apex; postmarginal band present, with perpendicular extension across 75% or more of fore wing width; connections from parastigmal band to stigmal band absent, and from stigmal band to postmarginal band absent. Hind wing hyaline. Gaster yellow with dark median and transverse bands.

Upper ocular sulcus present. Pedicel longer than wide or subequal. Funiculars symmetrical: first longer than wide (w:l = 0.57–0.7); second longer than wide (w:l = 0.8).

Pronotum, in dorsal view, bell-shaped (w:l = 1.37–1.5); 4–5 pairs of setae along posterior margin. Mesoscutum reticulate; small, scattered setae present; intermediate setae present. Mesoscutellum wider than long (w:l = 1.05–1.16); submedian grooves present. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus subequal or longer than second tarsomere (bst:2 nd = 1.04–1.14).

Fore wing l:w = 2.37–2.48. Submarginal vein with 7–8 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 1.07–1.62 mm; occiput yellow, or yellow with 2 dark, stripes; postmarginal band present, with perpendicular extension greater than that of stigmal apex, but not across 75% or more of fore wing width; metafemur yellow; gaster with markings fainter than those in females.

Remarks. Gordh (1978) synonymized Z. interlineatum   with Z. multilineatum   due to a lack of structural characters to differentiate the two species and the color patterns falling within the range of Z. multilineatum   . Girault (1916a) also mentions a metallic line on the gaster, however, there are no metallic markings on this species. Zagrammosoma interlineatum   was not successfully sequenced, but the color characters are informative, most notably in the wing and mesosoma patterns, and the species status is revised.

Girault (1916a) did not designate paratypes for Z. interlineatum   , but there is a series of specimens housed at the USNM with type labels bearing the number 9641 (UCRCENT471478–471481). Girault (1916a) mentions that the holotype number is 19641, and the specimens from the 9641 series agree with the holotype description.

Hosts. Reared from coleopteran, dipteran, and lepidopteran leaf miners. See Table 3. Coleoptera   : Curculionidae   . Diptera   : Agromyzidae   . Lepidoptera   : Cosmopterigidae   , Gelechiidae   , Gracillariidae   , Heliozelidae   , Tischeriidae   .
