47. Ochrilidia gracilis (Krauss, 1902)

Diagnosis: It can be identified by its temporal foveolae very narrow, elongate and slit like, invisible from above; vertex as long as wide; antennal segments 2–8 widened and flattened, straight lateral pronotal carinae; hind femur without black spots on inner side of knees.

Habitats: This species is most predominant in wet grasslands. It is also found in coastal and salt marshes in Libya. Light trap catches are commonly recorded. It indicates that this species is probably highly mobile. Times of capture in Egypt and Libya indicate the possibility of seasonal movement between these regions. It has been recorded feeding on wheat and cotton.
