1 Introduction
The subfamily Peiratinae occurs world-wide with the tropical areas of African and Oriental
Regions richest. This subfamily is a medium sized in the family Reduviidae. About 380
species 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 pests
in the field ( Ambrose, 1990)
In the Viet Nam, so far only 3 genera and 4 species of the Peiratinae have been
reported (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 subfamily
Peiratinae. One of them was new species of genus Sirthenea . The present paper, we also
review and new report more several species that were previously unknown from there. All
the measurements are in millimeters. This research is supported by The National Natural
Science Foundation of Vietnam (No. 6.021.06, Truong Xuan Lam)
