Brevennia rehi (Lindinger)

(Fig. 5)

Ripersia rehi Lindinger, 1943a: 152 . Ripersia sacchari oryzae Fletcher, 1917: 177 . Ripersia oryzae Green, 1931: 557 . Rhizoecus cynodontis Bodenheimer, 1943: 16 . Brevennia femoralis Borchsenius, 1949: 270 . Heterococcus tuttlei Miller & McKenzie, 1970: 447 .

DIAGNOSIS. Mounted adult female elongate oval to broadly oval. Legs short for size of body, with numerous transclucent pores on each hind femur and tibia. Antennae 6 or 7 segmented. Cerarii numbering 5 or 6 pairs, present on posterior segments of abdomen, each with a single conical seta, except anal lobe cerarii with 2 or 3 setae, but devoid of trilocular. Only posterior pair of ostioles present. Dorsal multilocular disc pores present across posterior abdominal segments VI–VIII, and around lateral margins of head and thorax; also on venter, along posterior edges of abdominal segment VII, posterior to vulva, and around lateral margins. Quinquelocular pores abundant on dorsum and venter. Trilocular pores present around spiracular opening and sparse across middle of dorsal segments between rows of quinquelocular pores. Oral collar ducts small, located mainly across venter of posterior abdominal segments and only 1 or 2 on dorsal abdominal segments VI and VII.

DISTRIBUTION. Australasian, Nearctic, Neotropical, Oriental, Palaearctic: Afghanistan, Azerbaijan, Egypt, Iraq, Iran, Israel, Tajikistan and Turkmenistan. In Iran, occurs in Khouzestan. B. rehi is known on Cyperaceae , Juncaceae and Poaceae (Ben-Dov et al., 2012) .

MATERIAL EXAMINED. Khouzestan: Ahvaz, 3 adult Ƥ, on Sorghum sp. ( Poaceae ), 19.vii.1990 (Asadeh); Ahvaz, Shoaybeh, 14 adult Ƥ, on Echinochloa crus-galli (Poaceae) , 14.x.2005 (A. Narrehei); Shush, Shaver, 9 adult Ƥ, on Oriza sativa (Poaceae) , 11.xi.2009 (V. Khosravi).

COMMENTS. B. rehi is known from many grass species, and it is often a serious pest on rice in Pakistan, India and Bangladesh (Williams, 2004). This species was reported from Iran by Asadeh & Mosadegh (1991), and since then it has been considered as a pest on sorghum and rice in the south of Iran. Due to this damage in southern Iran, a study of its life history under Iranian conditions should be done.
