Planiculus immersus (Schedl) , comb. n.

Xyleborus immersus Schedl, 1972b

Xyleborus hashimotoi Browne, 1986 , syn. n.

Specimens examined. P. immersus : New Guinea, East New Britain, Lakunai (holotype, NHMW); New Guinea, Madang Province, Baiteta (1, Hulcr det., IRSNB); New Guinea, Madang Prov. (540, Hulcr det., MSUC), Oro Prov. (1, Hulcr det., MSUC), West Sepik (23, Hulcr det., MSUC). X. hashimotoi : New Guinea, West Papua, Fakfak, imported to Japan (Nagoya) (holotype, BMNH).

Comments. This species’s placement in Planiculus is supported by both morphological and molecular phylogenetic analyses (100% posterior probability, Cognato et al. 2010). Wood and Bright (1992) indicated that the type specimen is in ANIC; but it is in NHMW. The type of X. hashimotoi is identical to P. immersus , including the exact position of tubercles on elytral declivity.
