Zagrammosoma headricki Perry n. sp.

( Fig. 19 )

Diagnosis. Zagrammosoma headricki is characterized by a dark gaster, and mesosoma that is almost the color inverse of other Zagrammosoma . The dark mesosoma displays yellow lines that follow the interior margins of the notaulus and axillae. The mesoscutellum is also dark, except for the outer margins, which are light yellow ( Fig. 19D, E ). The parastigmal band also connects with the cubital band ( Fig. 19C ), and the cubital band is occasionally wide enough to reach the posterior margin of the fore wing. The face is similar to Z. hobbesi , with the “tiger stripes” present, but the wing patterns are different ( Fig. 19C vs 21C), and there is no yellow found on the mesoscutellum of Z. hobbesi ( Fig. 21D, E ).

Description. Female - body length 0.77–1.6 mm. Metallic luster on body absent. Scape yellow, dorsally with black stripe. Two vertical stripes on lower face present. Vertex with 2 stripes above compound eye. Gena posteriorly with dark stripes below compound eye. Occiput dark, with no yellow stripes, or with 5 dark stripes radiating outwards from occipital foramen ( Fig. 19D ). Pronotum dark, dorsally with yellow stripes on lateral margins; laterally with 2 dark stripes. Prepectus yellow with dark stripe along dorsal margin. Mesoscutum dark, with yellow along notaulus; median stripe rarely visible ( Fig. 19D ). Mesoscutellum all black, or with three faint dark stripes that are difficult to distinguish from surrounding dark coloration. Propodeum dark with yellow on lateral margins. Procoxa yellow or dark. Mesocoxa all yellow, all dark, or yellow and basally dark. Metacoxa yellow or dark. Profemur yellow. Mesofemur all yellow or yellow with dark spot dorsally. Metafemur yellow or dark, or with dark banding encircling femur. Fore wing: basal band absent; cubital band present; parastigmal, stigmal, and postmarginal bands present, with perpendicular extension greater than that of the stigmal-parastigmal band reaching cubital band and posterior margin of wing; connection from parastigmal band to stigmal band absent; connection from stigmal band to postmarginal band absent. Hind wing hyaline. Gaster all dark, or with faint yellow on base of Gt 1.

Upper ocular sulcus present. Pedicel longer than wide. Funiculars symmetrical: first wider than long (w:l = 1.25–1.29); second wider than long (w:l = 1.55–2.08).

Pronotum, in dorsal view, more than twice as wide as long (w:l = 2.12–2.38); 3–5 pairs of setae on posterior margin. Mesoscutum reticulate; small, scattered setae present; intermediate setae absent. Mesoscutellum wider than long (w:l = 1.14–1.23); submedian grooves absent. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus shorter than second tarsomere (bst:2 nd = 0.7–0.83).

Fore wing l:w = 2.2–2.52. Submarginal vein with 5–6 setae dorsally. Basal fold setose. Cubital fold setose. Admarginal setae present in one or two rows. Uncus originating on stigma by more than own length from stigmal apex.

Male - as female, except: body length 0.8–1.01 mm; scape all yellow, or yellow with black stripe dorsally; occiput with 2 dark, vertical stripes present or absent ( Fig. 19E ).

Remarks. The dark coloration on the mesoscutum is sometimes faint enough to see the median dark stripe ( Fig. 19D ) that is present in the majority of other species of Zagrammosoma .

Hosts. Reared from a coleopteran leaf miner and a variety of leaf miners of unknown orders. See Table 3. Coleoptera : Chrysomelidae : Monoxi sp.

Distribution. Nearctic: Mexico (SL), USA (AZ, CA, TX) ( Fig. 20 ).

Etymology. This is the first new species of Zagrammosoma that I discovered; named in honor of Dr. David Headrick, who inspired me to pursue a career in entomology.
