Zagrammosoma deliae Perry n. sp.

( Fig. 14 )

Diagnosis. The most distinguishing character for Z. deliae is the extension of the parastigmal band towards the apex of the wing, almost connecting with the stigmal band ( Fig. 14C ). This character is sometimes found in Z. multilineatum , however the setal density and location on the fore wing varies between the species. In Z. deliae , setae are present adjacent to the admarginal setae, whereas the setae do not approach the admarginal setae in Z. multilineatum ( Fig. 34C ). In addition, the speculum is less setose in Z. multilineatum than in Z. deliae .

Description. Female - body length 1.18–1.4 mm. Metallic luster on body absent. Lower face with median stripe present. Vertex with 2 stripes above compound eye. Gena posteriorly with dark stripes below compound eye. Occiput with two dark, vertical stripes. Pronotum with median stripe complete; laterally with 2 black stripes. Prepectus yellow with dark stripe along dorsal margin. Mesoscutum with median stripe complete. Mesoscutellum with one or three dark lines. Propodeum yellow with black median carina, anterior and posterior margins, and diagonal line connecting anterior and posterior margins. Procoxa and mesocoxa yellow. Metacoxa yellow; basally with black stripe. Profemur and mesofemur yellow. Metafemur yellow with uninterrupted or interrupted stripe dorsally. Fore wing: basal band absent; cubital band absent or present; parastigmal, stigmal, and postmarginal bands present, with perpendicular extension greater than that of the stigmal apex; connection from parastigmal band to stigmal band absent or present. Hind wing hyaline. Gaster yellow with dark median stripe and transverse stripes.

Upper ocular sulcus absent. Pedicel longer than wide. Funiculars symmetrical: first longer than wide (w:l = 0.54–0.83); second subequal (w:l = 1.0).

Pronotum, in dorsal view, bell-shaped (w:l = 1.24–1.46); 3–4 pairs of setae along posterior margin. Mesoscutum reticulate; small, scattered setae absent; intermediate setae present. Mesoscutellum wider than long (w:l = 1.07–1.2); submedian grooves present. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus subequal or longer than second tarsomere (bst:2 nd = 1.0–1.29).

Fore wing l:w = 2.24–2.43. 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 0.87–1.02 mm

Remarks. This is the only species recovered from Peru. There can be slight variations on the mesoscutum (dark lines along anterior margins of notaulus and axilla) and mesoscutellum (one or three stripes) in Z. deliae ( Fig. 14D, E ), however the head and wing patterns are consistent throughout all specimens examined.

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

Distribution. Neotropical: Peru ( Fig. 9 ).

Etymology. Named after my Peruvian grandmother, Delia Oliden Martinez.
