Wallacellus striatulus (Browne), comb. n.

Xyleborus striatulus Browne, 1980

Specimens examined. New Guinea, East Sepik, Vanimo (holotype, BMNH), imported to Japan (Nagoya); New Guinea, Madang Prov. (68, Hulcr det., MSUC), Oro Prov. (5, Hulcr det., MSUC).

Comments. W. striatulus superficially resembles Euwallacea spp., but just as W. similis, the end of interstriae 1 is broadened and with one or more of dominant tubercles (not always present), the second interstriae have 0 or minute tubercles, and the third interstriae have often with more prominent tubercles. It can be distinguished from most similar Wallacellus and Euwallacea by conspicuous strial furrows and interstrial ridges covering most of declivital surface.
