| description |
A dark, mostly blackish species. The vertex is a dirty yellow color, the face is yellow to white. The pronotum and scutellum are entirely blackish brown. The wings are almost entirely blackish brown, concolorous with the thorax, except for along the costal margin. There is a yellow stripe along almost the entire length of the costal margin, extending almost to the apical cross veins; the costal margin itself is a bold, contrasting yellow. The width of this yellow stripe varies among individuals, with some largely lacking the stripe; note that in individuals with thicker stripes, the yellow does not take up the entirety of the outer basal cell and remains more or less straight. The underside of the thorax and abdomen are yellow, except for the pregenital sternite of males which is a solid brown; the abdomen is dark brown above with yellow segments. The subgenital plates are somewhat triangular in shape, with broad bases that strongly taper. Teneral individuals have two red longitudinal lines on the sides of the midline on the head, and the pronotum has a median red transverse line; there are red markings on the pronotum behind each eye. Adults are 3.7- 4.0 mm long. (Christian, 1956) |

| comments |
This species is very similar to in appearance to E. omani. Both species are almost entirely blacksih dorsally, with slight differences in the wing coloration. In E. nigra, there is a longitudinal yellow stripe along the costal margin, extending almost to the apical cross veins. However, in E. omani, the outer basal cell along the costal margin is white to pale yellow in color, extending to the apical cross veins. Rather than having a pale stripe along the costal margin, almost the entire outer wing cell is pale. The two species also differ in size: nigra is 3.75-4.0 mm long, while omani is 3.0-3.25 mm.
