(Fig. 48)
Diagnosis. This species can be differentiated from all other Zagrammosoma by the asymmetrical funiculars (Fig. 48A, B), mesoscutum and mesoscutellum with linear-reticulate sculpturing (Fig. 48E), and propodeum posteriorly with a very faint median carina that may be difficult to see. The color patterns are most similar to Z. latilineatum (Fig. 26), also found in the Indo-Malay, and the two species can be differentiated by the number of dark lines laterally on the pronotum: two in Z. latilineatum and three in Z. yanegai.
Description. Female - body length 0.75–0.8 mm. Metallic luster on body absent. Scape all yellow. Lower face with median stripe absent. Vertex with one stripe above compound eye. Gena posteriorly with wide, dark band below compound eye; yellow spot on ventral margin of compound eye. Occiput yellow with 2 dark, vertical stripes. Pronotum with median band or stripe complete; laterally with 3 dark stripes. Prepectus yellow with dark stripe along dorsal margin. Mesoscutum with median band or stripe complete. Mesoscutellum with one or three dark stripes. Propodeum yellow with dark markings laterally. Procoxa yellow with dark stripe or band basally. Mesocoxa yellow with faint, dark transverse band. Metacoxa yellow with black stripe or band basally and/or apically. Profemur and mesofemur yellow. Metafemur with interrupted stripe or dark band on outside of femur, tapering apically. 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 that of stigmal apex; postmarginal band absent; darkening of apical margin present; connection from parastigmal band to stigmal band absent. Hind wing hyaline. Gaster yellow with median and transverse stripes present.
Upper ocular sulcus absent. Pedicel subequal in width: length. Funiculars asymmetrical and subequal in width: length (w:l = 1.0).
Pronotum, in dorsal view, more than twice as wide as long (w:l = 2.29–2.44); 3 pairs of setae along posterior margin. Mesoscutum linear reticulate; small, scattered setae absent; intermediate setae present. Mesoscutellum wider than long (w:l = 1.45–1.51); submedian grooves absent or present but faint and shallow. Propodeum with median carina present posteriorly only. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus subequal in length to 2 nd tarsomere (bst:2 nd =1.0).
Fore wing l:w = 1.91–2.03. Submarginal vein with 5 setae dorsally. Basal fold setose. Cubital fold setose. Admarginal setae present. Uncus originating on stigma by more than own length from stigmal apex.
Male - unknown.
Remarks. This species is described from two specimens collected in Thailand and is one of two species found in the Indo-Malayan region. Even with the variable color patterns on the mesoscutum observed within the species Z. yanegai is morphologically distinct and is easy to identify by the asymmetrical funiculars and linear-reticulate sculpturing (Fig. 48B, D, F).
Hosts. Unknown.
Distribution. Indo-Malay: Thailand (Fig. 27).
Etymology. Named in honor of Dr. Doug Yanega, for his many years of taxonomic help and guidance.
