Zagrammosoma calvini Perry n. sp.

( Fig. 8 View FIGURE 8 )

Diagnosis. Zagrammosoma calvini is the only species to display three dark lines on the occiput, one vertical and the other two converging at the base of the occiput ( Fig. 8A View FIGURE 8 ). The fore wing also has a conspicuous asetose fold posterior to the cubital line of setae ( Fig. 8C View FIGURE 8 ). This species most resembles Z. villosum , which only has two vertical stripes on the occiput, and two dark lines laterally on the mesosoma ( Fig. 46B View FIGURE 46 ) whereas Z. calvini possesses three lines on the occiput and laterally on the mesosoma.

Description. Female - body length 0.84–2.02 mm. Metallic luster on body absent. Scape all yellow, or with dark stripe dorsally. Lower face without median stripe. Vertex with 2 stripes above compound eye. Gena posteriorly with wide, dark band below compound eye. Occiput yellow with 3 dark, vertical stripes. Pronotum with median stripe; laterally with three stripes. Mesoscutum with interrupted median stripe. Prepectus yellow with dorsal margin dark. Mesoscutellum with three dark lines, sometimes faint. Propodeum yellow with black median carina, and lateral spot. Procoxa and mesocoxa yellow. Metacoxa yellow, basally with dark spot. Profemur and mesofemur yellow. Metafemur yellow, or with spot laterally. 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 or greater than that of stigmal apex; postmarginal band absent or present with perpendicular extension less than that of stigmal apex. Hind wing hyaline. Gaster yellow with dark median and transverse stripes or bands.

Upper ocular sulcus present. Pedicel longer than wide. Funiculars symmetrical: first subequal or wider than long (w:l = 1.0–1.31); second wider than long (w:l = 1.18–1.51).

Pronotum, in dorsal view, bell-shaped or more than twice as wide as long (w:l = 1.75–2.75); 5–6 pairs of setae on posterior margin. Mesoscutum reticulate; small, scattered setae present; 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 = 0.85–0.89).

Fore wing l:w = 2.27–2.58. Submarginal vein with 5–7 setae dorsally. Basal fold setose. Cubital fold setose. Admarginal setae present. Uncus originating on stigma by its own length or less from stigmal apex, or by more than length of uncus.

Male - as female, except: body length 0.63–0.97 mm; occiput with 3 stripes, sometimes with a very faint median stripe; stigmal band present, with perpendicular extension only to apex of stigma; submarginal vein with 5 setae dorsally; uncus originating on stigma by its own length or less from stigmal apex.

Remarks. This is the only described species found in the southern half of South America. There are a series of Z. calvini specimens located at the USNM (UCRCENT471616–471636) that do not have any locality information other than “Reared at South American Parasite Laboratory, Montevideo, Uruguay,” and do not specify where the samples were actually collected.

Hosts. unknown.

Distribution. Neotropical: Argentina, Chile ( Fig. 9 View FIGURE 9 ).

Etymology. Named in memory of Dr. John LaSalle, who described Zagrammosoma hobbesi , which he named after Hobbes the tiger from Calvin & Hobbes. The characteristic number of setae present on the head and body of Z. calvini is reminiscent of Calvin’s spiked hair.
