Geographical distribution: Egypt (Sinai).
Morphology: The adult body is Length: 1.0–1.2 mm long, head brown, body black-brown with a yellow patches, antennae with 7 segments.
Life history: A parasitoid of P. blanchardi and F. phoenicis, whose populations have three peaks of abundance, in mid-winter, spring and in mid-summer. It mostly parasitizes hosts that infest the upper surfaces of date palm fronds.
Economic importance: An increasingly important natural enemy of P. blanchardi in northern Sinai, where it appears to be displacing the formerly-dominant Aphytis phoenicis DeBach and Rosen. Average parasitism rates due to F. phoenicis came to 41%, being highest in spring-summer.
