Eurycoccus tamariscus Williams, 1984: 538 .

DIAGNOSIS. Body of mounted adult female broadly oval, membranous. Antennae 6 segmented. Legs well developed, hind coxa with proximal edge indistinct. Translucent pores present on anterior and posterior surfaces of hind coxa and on posterior surface on hind tibia. Hind tibia + tarsus noticeably shorter than hind trochanter + femur. Cerarii only present on anal lobes, each bearing 2 flagellate setae, each stouter than surrounding setae. Ostioles well developed. Circulus absent. Spiracles large, situated near lateral margins. Dorsal setae flagellate, some on margins longer than those medially. Ventral setae similar to those on dorsum. Multilocular disc pores present on venter only, posterior to vulva and in medial transverse rows on posterior edges of abdominal segments IV–VII, with some reaching marginal areas. Trilocular pores evenly distributed. Discoidal pores, each with a thick rim, scattered on venter. Microducts present on dorsal surface. Oral collar ducts present on venter only, each about as wide as trilocular pores or slightly wider, sparse, 1 or 2 present submedially or marginally on abdominal segments VI and VII.

DISTRIBUTION. Oriental: Pakistan, Palaearctic: Iran. In Iran, E tamariscus occurs in Sistan & Baluchestan. It is only known on Tamaricaceae (Ben-Dov et al., 2012) .

MATERIAL EXAMIND. Sistan & Baluchestan: Bampour, 3 adult Ƥ, on Tamarix sp. ( Tamaricaceae ), 17.iv. 2005, 537 m. (Motamediniya).

COMMENTS. E. tamariscus was originally described from Pakistan, on Tamarix aphylla (Tamaricaceae) at Kalabagh and on T. indica at Gharo (Williams, 1984). E. tamariscus has now been collected on Tamarix sp. in Sistan and Balouchestan in galls apparently made by another insect.
