It is demonstrated that there is no valid basis on which to sustain the monotypic genus Bathycranium Strobl and concluded that Bathycranium should be recognised as a junior synonym of Syntormon Loew (new status). The species Syntormon bicolorellus Zetterstedt (new combination) falls into a natural grouping of Syntormon species with downcurved facial hairs in females. This species and S. luteicornis Parent are redescribed. Distinctions between Syntormonand Parasyntormon are discussed.
Long series of some species of Tetrigidae from south Asia show that the wings regularly project beyond the pronotal shield by some 15- 35 percent of their length, depending on the species. There is little intraspecific variation and alary polymorphism is not normally detectable. The role of such exposed wings is discussed and one new species is described. Most such species probably owe their evident relationship to evolution prior to the disintegration of the Gondwanaland super-continent.
