Zagrammosoma centrolineatum Crawford

( Fig. 10 )

Zagrammosoma centrolineata Crawford, 1913: 256 . Holotype ♀ [examined]. Type locality: USA, California, Los Angeles Co. Type depository: USNM type no. 15931- UCRCENT471417.

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

Diagnosis. This is the only species that possesses a wide, dark band dorsally that is continuous from the pronotum to the apex of the gaster. Both Z. latilineatum ( Fig. 26 ) and Z. seini ( Fig. 38 ) have wide bands on the mesosoma, but these bands are not as wide as those on Z. centrolineatum and do not extend onto the gaster. The hind basitarsus is longer than the second tarsomere in Z. centrolineatum , and shorter than the second tarsomere in both Z. latilineatum and Z. seini .

Description. Female - body length 1.31–2.25 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 wide median band complete; laterally with 2 black stripes. Mesoscutum with wide median band complete. Prepectus yellow with dorsal margin dark. Propodeum yellow with wide median band. Procoxa and mesocoxa yellow. Metacoxa yellow or, rarely, basally with dark spot. Profemur and mesofemur yellow. Metafemur variable: yellow, with uninterrupted stripe or interrupted stripe dorsally. Fore wing: basal band absent; cubital band present; parastigmal band present, at junction of parastigmal and marginal veins only; stigmal band present, with perpendicular extension greater than that of stigmal apex; postmarginal band present, with perpendicular extension across 75% or more of fore wing width, often across entire width; connection from cubital band to stigmal band present, in a wide, linear band. Hind wing hyaline. Gaster yellow with wide, dark band dorsally.

Upper ocular sulcus absent. Pedicel longer than wide. Funiculars symmetrical: first longer than wide (w:l 0.56–0.75); second longer than wide (w:l = 0.7–0.72).

Pronotum, in dorsal view, bell-shaped, wider than long (w:l = 1.39–1.45); 5 pairs of setae along posterior margin. Mesoscutum reticulate; small, scattered setae present.; intermediate setae absent. Mesoscutellum wider than long (w:l = 1.09–1.14); submedian grooves absent. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus longer than second tarsomere (bst:2 nd = 1.13–1.28).

Fore wing l:w = 2.51–2.77. Submarginal vein with 7 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 0.79–1.47 mm; body yellow, with wide dark band present only on mesosoma; gaster with interrupted median band, and transverse bands across Gt 4 –Gt 5 ( Fig. 10E ).

Remarks. This species is easy to identify due to the unique body and fore wing pattern and is widespread in the western Nearctic.

Hosts. Reared from lepidopteran leaf miners and an unknown gall. See Table 3. Lepidoptera : Gracillariidae , Heliozelidae .

Distribution. Nearctic: Canada (BC), USA (AZ, CA, NM, OR, TX, UT) ( Fig. 11 ).

Etymology. Named for the dark, broad median band that extends from the anterior margin of the pronotum to the tip of the gaster.
