A. Grewell/ At black light/ CAMBODIA/ HOLOTYPE Oedichirus sihanouki Des. 2017 G. de Rougemont[ FMC].  Description: length: ca. 7.6 mm; length of fore-body: 2.1; length of head: 0.62; breadth of head: 0.89; length of antenna: 1.7; length of elytron: 1.15; breadth of elytra: 1.25. Head black, pronotum red, anterior 3/4 thsof elytra black, posterior 1/4 thred, abdominal segment III-VI red, VII-IX black; mouthparts, antennae and legs entirely testaceous. Body devoid of microsculpture except around basal keels of abdominal tergites. Pubescence of elytra and abdomen fairly sparse, fine, pale, moderately long, erect. Habitus: Fig. 8h. Head slightly narrower then pronotum; eyes very large; post-ocular border well marked by a punctate groove and carina which does not form a tooth behind the eye; disc of head sparsely punctate, with a circle of ca. ten punctures in anterior half of head, the anterior punctures very fine, the posterior ones larger, a series of about six small punctures extending from antennal tubercle along inner margin of eye, and three setiferous punctures arising from the post-ocular grooves. Pronotum short and broad; lateral margins not bordered; disc with a pair of discal series of six punctures each, two pairs of punctures above this, five punctures on anterior and anterior lateral margin, and a single puncture on posterior lateral margin. Fully winged, elytra short and broad, with a juxta-sutural series of about eight punctures and numerous punctures in anterior 2/3 rds, more sparsely punctate laterally. Abdominal puncturation arranged in three discrete transverse rows. Male: sternite VII unmodified; sternite VIII (Fig. 8s8) with an asymmetrical posterior margin, a membranous flange and a comb of setae; aedoeagus: Fig. 8arl, the right paramere free, long and sinuate.   O. sihanouki nov.sp.is the only oriental species with the same colour pattern as  O. chapmaniCam.(bicolorous elytra, with four red abdominal segments), but is a smaller insect, with pronotal discal series of six instead of four punctures, less extensive red portion of elytra and denser puncturation of the elytra.  Distribution: Map 2. Key 1 Waza is not a locality, but the acronym of the World Association of Zoos and Aqariums, which has conducted research in the Cardamom Hills of western Cambodia. 4854171447 1972-03-19 At black light FMC J.
