Zagrammosoma galapagoense Perry n. sp.

( Fig. 18 View FIGURE 18 )

Diagnosis. The most visible character defining Z. galapagoense is the dark, transverse stripe running along the posterior margin of the mesoscutum ( Fig. 18D, E View FIGURE 18 ). The mesosomal patterns are very similar to Z. multilineatum and Z. deliae , however the wing patterns are slightly different between the species, and Z. galapagoense is the only species of the three to possess two rows of admarginal setae, compared to one in the other two species ( Figs 18C View FIGURE 18 versus 14C, 34C), The submedian grooves are absent in Z. galapagoense and present in the other two species. The second funicular in Z. multilineatum is longer than wide, but wider than long in Z. galapagoense .

Description. Female - body length 1.12–1.57 mm. Metallic luster on body absent. Scape yellow with black stripe dorsally. Lower face with median stripe present. 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 stripe complete; laterally with 2 black 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, and diagonal line connecting anterior and posterior margins. Procoxa and mesocoxa yellow. Metacoxa yellow; basally with black stripe. Profemur and mesofemur yellow. Metafemur with uninterrupted stripe dorsally. Fore wing: basal band absent; cubital band 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; connection 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 or subequal (w:l = 0.83–1.0); second wider than long (w:l = 1.2–1.5).

Pronotum, in dorsal view, bell-shaped (w:l = 1.34–1.57); 4–5 pairs of setae on posterior margin. Mesoscutum reticulate; small, scattered setate present; intermediate setae present. Mesoscutellum wider than long (w:l = 1.12– 1.18); submedian grooves absent. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus longer than second tarsomere, (bst:2 nd = 1.11–1.24).

Fore wing l:w = 2.07–2.55. 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 0.83 mm (only one male examined); submarginal vein with 5 setae dorsally.

Remarks. One of two endemic species in the Galapagos Islands, Z. galapagoense is much more rarely encountered than the other two species found in the archipelago, Z. buselus and Z. multilineatum . Only one specimen (D5888) had DNA successfully amplified, and emerges distinct from the other two species in the archipelago ( Fig. 2 View FIGURE 2 ).

Hosts. Unknown.

Distribution. Neotropical: Ecuador (Galapagos) ( Fig. 7 View FIGURE 7 ).

Etymology. Named after the Galapagos Islands.
