Zagrammosoma seini Wolcott

(Fig. 38)

Zagrammosoma seini Wolcott, 1936: 525. Lectotype ♀. Locality: USA, Puerto Rico, Lares, 318m, xii.1934 - ii.1935, F. Sein, “PR 14-35”, host: Leucoptera coffeella (Lepidoptera: Lyonetiidae): [UCRCENT 416789], by present designation for nomenclatural stability; deposited at USNM.

Cirrospilus (Zagrammosoma) seini; incorrect combination and subgenus designation by DeSantis 1979: 261.

Diagnosis. Zagrammosoma seini is characterized by the presence of both a wide, medial band dorsally on the mesoscutum and darkening of the fore wing apical margin. The mesosoma pattern is similar in Z. latilineatum, but the median band is thinner in Z. seini than in Z. latilineatum (Fig. 38D, E versus 26D, E), and Z. latilineatum lacks the apical band of the fore wing. Zagrammosoma yanegai also has similar color patterns of the wings and mesosoma (Fig. 48F), however Z. yanegai possesses asymmetrical funiculars (Fig. 48A) and a less developed median carina on the propodeum.

Description. Female - body length 1.62–1.99 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. Dark stripe and band below compound eye yellow. Occiput yellow with 2 dark, vertical stripes. Pronotum with median band complete; laterally with 2 dark stripes. Mesoscutum with median band complete. Prepectus yellow with black stripe along dorsal margin. Mesoscutellum yellow with median band. Propodeum yellow with black median carina and diagonal line. Procoxa and mesocoxa yellow. Metacoxa yellow with black stripe basally. Profemur, mesofemur, and metafemur yellow. Fore wing: basal and cubital bands absent; parastigmal band present, at junction of parastigmal and marginal veins only; stigmal band present, with perpendicular extension greater than that of stigmal apex; postmarginal band absent; apical band present; connections from parastigmal band to stigmal band, and from stigmal band to postmarginal band absent. Hind wing hyaline. Gaster yellow with median black stripe; black stripe laterally.

Upper ocular sulcus present. Pedicel longer than wide. Funiculars symmetrical: first longer than wide (w:l = 0.43–0.46); second longer than wide (w:l = 0.61–0.7).

Pronotum, in dorsal view, bell-shaped (w:l = 1.4–1.94); 3 pairs of setae along posterior margin. Mesoscutum reticulate; small, scattered setae present; intermediate setae absent. Mesoscutellum wider than long (w:l = 1.15–1.25); submedian grooves absent. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus shorter than second tarsomere (bst:2 nd = 0.63–0.89).

Fore wing l:w = 2.24–2.26. Submarginal vein with 5–7 setae dorsally. Basal fold setae absent, or with one to two setae. Cubital fold setose.Admarginal setae present. Uncus originating on stigma by more than own length from stigmal apex.

Male - as female, except: body length 1.05–1.37 mm; gaster with median stripe not complete.

Remarks. Wolcott (1936) did not designate a holotype or depository when describing this species. The specimens he described were from “mines of Leucoptera coffeella Guerin on coffee at Lares (152-21, 14-35 generic determination by A. B. Gahan).” There are two female specimens housed at the USNM that are reared from L. coffeella, one with the Accession number 152-21 collected from Lares, and the other with “P.R. 14-35” collected from “ Lares or Isabela.” The latter was collected by F. Sein. It is presumed that these are the specimens Wolcott used in his description of Z. seini, and therefore, a lectotype and paralectotype are assigned here.

Hosts. Reared from lepidopteran leaf miners. See Table 3. Lepidoptera: Gracillariidae, Lyonetiidae, Pyralidae, Tischeriidae.
