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.

MtCOI DNA sequences from Sycanus aurantiacus (Hemiptera: Heteroptera: Reduviidae) provide evidence of a possible new harpactorine species from Bali, Indonesia

“…S. aurantiacus was found (in 2019) in a farmer's plastic house in the Bedugul region of Bali, in an area of especially abundant moss in Pancasari Village. The observation differed somewhat that described previously by Ishikawa et al (2007) and Yuliadhi et al (2015) who reported that the species was an important predator of some key lepidopteran cabbage pests. However, now the species was being found in abundance in farmer's plastic house containing various crops.…”

“…A new species Sycanus aurantiacus Ishikawa & Okajima was discovered in 2004 by researchers conducting a project on "Development of New Bio-Agents for Alternative Farming Systems" conducted by the Tokyo University of Agriculture in collaboration with Udayana University. The new harpactorine species from Bali was first formally described in a publication in 2007, based primarily on morphological characteristics (Ishikawa et al 2007). S. aurantiacus was observed in cabbage plantations across the Bedugul region, including Pancasari (which lies more than 1,000 m above sea level).…”

Revision of the Genus <em>Sycanus</em> Amyot & Serville, 1843 (Heteroptera: Reduviidae: Harpactorinae) from China Based on DNA Barcoding and Morphological Evidence

“…The genus Sycanus was established by Amyot & Serville in 1843 for the oriental species, Reduvius collaris Fabricius, 1781 as the type species, with seventy-six Oriental and one Madagascar known species [22][23][24][25]. The beautiful assassin bugs are easily separated from other allied genera by the following characters: the head is much longer than the pronotum, the scutellum is apically armed with a spine or tubercle, and the connexivum of abdomen is extremely laterally dilated.…”
