description |
A white to gray species with black and fuscous markings. The vertex is yellowish to whitish in color except for the black muscle arcs on the face (the two black transverse dashes near the margin of the head) that extend onto the crown; there are also some fuscous marks as well. The markings on the head are described as follows: "reflexed arcs of face, a pair of spots just back of apex, another either side of midway to eye, an irregular interrupted band, broadest at middle, between anterior margins of eyes, and an indefinite spot on either side behind band" (DeLong 1948). The scutellum has a large black spot at each basal angle (the anterior corners). The wings are a pale yellowish to white color, with some of the wing cells a grayish color with black borders. The female pregenital sternite rises abruptly from the preceding segment, with a truncated posterior margin; the lateral lobes are produced beyond the median portion as rounded lobes, and there is no median notch or excavation. The male genital plates are triangular, with broad bases that strongly and concavely narrow to attenuated tips. Adults males are 3.1-3.2 mm long, while females are around 3.1 mm long. (DeLong 1948)
