Sycanus aurantiacus (Hemiptera: Heteroptera: Reduviidae), a new harpactorine species from Bali, Indonesia, with brief notes on its biology

Abstract

A new species, Sycanus aurantiacus, of the assassin bug subfamily Harpactorinae is described on the basis of specimens collected from Bali, Indonesia. This species is distinguished from the other species of Sycanus by its antennal segment I having two orange annulations; the posterior pronotal lobe being weakly tumid in the middle near the posterior margin; the scutellar spine being erect, short, and rounded at the apex; each femur having two incomplete orange annulations; the hemelytral corium being blackish with the veins yellow to yellowish brown; and the abdominal laterotergites being weakly extended dorsad. This species is notable because it feeds on some serious lepidopteran pests of cabbage.
