in rattan articles and wooden packing cases. Miller (1934) stated 

 that this species is the most important pest of maize in Mauritius and 

 in Zanzibar. This species reduces all structures built of bamboo to 

 dust in a few years. It has been intercepted in Arunclo donax and 

 Merostachys racimaflora from Mexico. 



Fabricius (1775) described this species from a specimen in the Banks 

 Collection from New Zealand. Stephens (1830) misiclentifiecl this 

 species as substriatus Paykull from a specimen collected in England 

 and placed it in his genus Dinoderus. Waterhouse (1888) stated that, 

 after examining the specimen identified as substriatus by Stephens, 

 there could be no doubt that it is Apate minuta Fabricius, from New 

 Zealand, but most unfortunately the type of minuta is no longer to be 

 found in the Banks Collection. Walker (1859) described vertens from 

 Ceylon. Baudi (1873) described Rhizopertha sicula from Sicily. 

 Matsumura (1915) described this species as japoniciis (not Lesne). 

 Lesne (1898) placed substriatus Steph. (not Payk.) , statins Baudi, and 

 bifoveolatus Zoufal (not Wolls.) as synonyms of inhnitus F. and 

 he (1938) also included vertens Walker and japonicus Matsuni. (not 

 Lesne) as synonyms of this species.
