new genus

Prototympanogaster  , new genus

Type species: Prototympanogaster lordhowensis  , new species.

With characteristics as described for the type species. The neW genus appears most closely related to Tympanogaster Perkins, 1979  . Tympanogaster  currently has four subgenera and 84 species, mostly found in the relict eastern rainforests of Australia ( Perkins, 2006). The neW genus is named in reference to the putative

plesiomorphic condition of the metaventrite, Which is totally hydrofuge pubescent ( Fig. 1), Whereas members of Tympanogaster  have a large, non-pubescent tabella ( Figs. 2, 4 View Figure , 6 View Figure ).
