Zagrammosoma latilineatum Ubaidillah

(Fig. 26)

Zagrammosoma latilineatum Ubaidillah, 2000: 223–225. Holotype ♀. Locality: Indonesia, West Java, Pangalengan, Bandung, coll. A. Rauf, 11.xi.1988, host: Liriomyza huidobrensis (Diptera: Agromyzidae), host plant: potato. Depository: Museum Zoologicum Bogoriense, Bogor, Indonesia.

Diagnosis. Zagrammosoma latilineatum has a wide, dark band dorsally on the mesosoma, which is similar to the band found in Z. centrolineatum and Z. seini. The band is wider in Z. centrolineatum and also continues through the gaster (Fig. 10D, E). The band is wider than the band in Z. seini, and there is darkening of the apical margin of the fore wing in Z. seini (Fig. 38C), which is absent in Z. latilineatum.

Description. Female – body length 0.84–1.6 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 wide, dark band below compound eye. Occiput yellow with 2 dark, vertical stripes. Pronotum with median band complete; laterally with 2 black stripes. Prepectus yellow with dark stripe along dorsal margin. Mesoscutum with wide, dark band complete. Mesoscutellum with median band complete. Propodeum dark. Procoxa, mesocoxa, and metacoxa yellow. Profemur and mesofemur yellow. Metafemur with interrupted stripe dorsally. Fore wing: basal and cubital bands absent; parastigmal band present, at junction of parastigmal and marginal veins only; stigmal band present, with perpendicular extension less than that of stigmal apex; postmarginal band absent; connections from parastigmal band to stigmal band and from stigmal band to postmarginal band absent. Hind wing hyaline. Gaster yellow with dark median and transverse stripes present.

Upper ocular sulcus present. Pedicel longer than wide. Funiculars symmetrical: first longer than wide to wider than long (w:l = 0.65–1.08); second subequal or wider than long (w:l = 1.0–1.38).

Pronotum, in dorsal view, bell-shaped or more than twice as wide as long (w:l = 1.3–2.24); 3–4 pairs of bristles along posterior margin. Mesoscutum reticulate; small, scattered setae absent; intermediate setae present. Mesoscutellum wider than long (w:l = 1.06–1.11); submedian grooves present. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus shorter than second tarsomere (bst:2 nd = 0.78–0.85).

Fore wing l:w = 2.41–2.63. Submarginal vein with 4–5 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 0.85–1.29 mm; gaster yellow with dark lateral margin and two median spots on Gt 3–4 and Gt 5–6.

Remarks. One of two species in the Australasian and Indo-Malayan regions, and the only species found in Australia, where it is very widespread, being found even in the center of the country in the Amadeus Basin.

Hosts. Reared from dipteran and lepidopteran leaf miners. See Table 3. Diptera: Agromyzidae. Lepidoptera: Gracillariidae.

Distribution. Australasia: Australia (ACT, NSW, NT, QLD, SA, WA). Indo-Malay: Indonesia (Fig. 27).

Etymology. Latilineatum is Latin for “wide lined,”, describing the dark band on the dorsum of the mesosoma.
