Typhlocyba querci |
| description |
A pale yellowish species. The head, pronotum, and scutellum are white to bright yellow-orange. The forewing is white to bright yellow-orange anterior to the apical crossveins. This species lacks dark marking or bands on the basal 2/3 of the tegmen/wings that are characteristic of most other members of this genus. The apex of the tegmen has 3 dark brown to black spots in a straight row, in the apices of the second and third basal and first apical cells; sometimes there are traces of color in the first basal and bases of the second and fourth apical cells, appearing as small spots. The wing venation is white to yellow-orange, hyaline areas are anterior to the apical crossveins; the apical cells can have a slight smoky tinge to them. Adults are 3.25-3.5 mm long. (Christian, 1953, Hamilton, 1983) |

| comments |
Note: There are some species of Ossiannilssonola that are similar to Empoa querci, in wing color and the presence of three spots near the apical cells. However, Empoa and Ossiannilssonola have different wing venation that can be helpful in differentiating. In Ossiannilssonola, the apical crossveins are fairly straight for the upper portion of the wing; in Empoa, the crossveins are not straight and instead form a jagged, angled line. |
