Checklist of Genera of Mesostenini, by Subtrihes 



The hst below is arranged by relationships, according to the present 

 rudimentary understanding of these, and according to the limitations 

 of a hnear sequence. Now synonyms are marked with an asterisk. 

 The described genera of the world are included except for Allophatnus, 

 Scenopathus, Neomesostenus, and Cylindrocryptus. Of these missing 

 genera, we have seen only Neomesostenus. Our notes on Neomesos- 

 tenus are not sufficient to place it with certainty but it is likely related 

 to Lymeon. Allophatnus and Scenopathus belong probably in the 

 Mesostenina. Cylindrocryptus may belong in the Mesostenina or in 

 the Hemigasterini. The identity of Hoeocryptus is uncertain. We 

 have not seen an authentic specimen but list it in the synonymy of 

 Brachycoryphus on the authority of Roman (1910, Ent. Tidskr., vol. 

 31, p. 149).
