Key to the Genera of Meropathina 

1. Prothorax with deep hypomeral antenna pocket that is bordered laterally by wide wet hypomeron that bears prominent, stiff hypomeral antennal pocket setae ( Figs. 1, 2, 4 View Figure , 10 View Figure )........................................................... 2

- Antennal club held in relatively shallow, at least partially pubescent hypomeron that does not bear hypomeral antennal pocket setae ( Figs. 12 View Figure , 15, 17 View Figure )................................................................................. 3

2. Metaventrite transversely convex and entirely hydrofuge pubescent; Lord Howe Island ( Fig. 1).................................................................................................... Prototympanogaster  new genus

- Metaventrite with large glabrous tabella; Australia, primarily eastern relict rainforests ( Figs. 2, 4 View Figure , 6, 7 View Figure )..................................................................................................... Tympanogaster Perkins 

3. Occipital area of head with three parallel longitudinal carinae ( Fig. 14 View Figure ); gula with three longitudinal carinae (fig. 17); mentum elongate, rectangular, and notched at anterior margin for reception of labial palpi, which have tips overlapping ( Figs. 18, 19 View Figure ); metaventrite long, with midlongitudinal groove and very sparse non-hydrofuge setae; southeastern Australia............................................................................................... Tympallopatrum Perkins   

- Occipital area of head without carinae ( Figs. 3, 5 View Figure ); gula without carinae ( Fig. 3, 5 View Figure , 12 View Figure ); mentum quadrate, labial palpi well separated ( Fig. 22 View Figure ); metaventrite short, entirely hydrofuge pubescent ( Figs. 8, 9 View Figure ); subantarctic islands and islands near New Zealand...............................................................................
