This subfamily is a medium sized in the family Reduviidae. About 380species in 27 genus have been known in the world (Putshkov & Putshkov, 1985; Maldonado-Capriles, 1990). Some of them can be find in agricultural crops such as Rice, Soybean,Cotton, Corn, Peanut, and playing an important role in the natural control of insect pestsin the field ( Ambrose, 1990) In the Viet Nam, so far only 3 genera and 4 species of the Peiratinae have beenreported (Serville, 1831; Distant, 1904, 1919; Hsiao & Ren, 1981; Maldonado-Capriles,1990, Cai & Lu, 1990, 1991; Putshkov & Putshkov, 1996). Recently, Cai & Tomokuni(2004) have been new reported more 4 species and 1 genus belonging to the subfamilyPeiratinae. One of them was new species of genus Sirthenea . The present paper, we alsoreview and new report more several species that were previously unknown from there. Allthe measurements are in millimeters.
