Cyclorhipidion sus Schedl, comb. n.

Cyclorhipidion sus (Schedl), comb. n.

Xyleborus sus Schedl, 1973 b

Arixyleborus sus (Schedl, 1979b)

Specimens examined. C. sus: New Guinea, Moroko, Loria (holotype, NHMW); New Guinea, Morobe Province, Bulolo (1, Hulcr det. FICB); New Guinea, Morobe Province, Bulolo (1, Hulcr det. NHMW); New Guinea, Oro Prov. (32, Hulcr det., MSUC).

Comparative specimens: C. multipunctatum (Browne): Malaysia, Borneo, Tatau, imported to Nagoya, Japan (holotype, BMNH); New Guinea, Kupa Range (FICB, Hulcr det.); PNG, Chimbu Prov. (13, Hulcr det., MSUC).

Comments. C. sus shares two characters with Arixyleborus: several rows of tubercles on posterior face of protibia, and rows of tubercles in elytral striae. The two characters are also present in some Cyclorhipidion, notably the almost identical sympatric C. multipunctatum. C. sus and C. multipunctatum are sister taxa in molecular phylogeny (100% posterior probability, Cognato et al. 2010). C. sus shares many synapomorphies with Cyclorhipidion in general: rounded lateral outline of pronotum, thick femora, rounded dorsal outline of abdomen; dense uniform vestiture; antennal club type 3; small and numerous denticles on tibial edges; and the outer edges of all tibiae are evenly convex.
