Key to the Genera of Meropathina View in CoL

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 FIGURES 2–5 , 10 View FIGURES 10–13 )........................................................... 2

- Antennal club held in relatively shallow, at least partially pubescent hypomeron that does not bear hypomeral antennal pocket setae ( Figs. 12 View FIGURES 10–13 , 15, 17 View FIGURES 14–19 )................................................................................. 3

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

- Metaventrite with large glabrous tabella; Australia, primarily eastern relict rainforests ( Figs. 2, 4 View FIGURES 2–5 , 6, 7 View FIGURES 6–9 )..................................................................................................... Tympanogaster Perkins View in CoL

3. Occipital area of head with three parallel longitudinal carinae ( Fig. 14 View FIGURES 14–19 ); 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 FIGURES 14–19 ); metaventrite long, with midlongitudinal groove and very sparse non-hydrofuge setae; southeastern Australia............................................................................................... Tympallopatrum Perkins View in CoL

- Occipital area of head without carinae ( Figs. 3, 5 View FIGURES 2–5 ); gula without carinae ( Fig. 3, 5 View FIGURES 2–5 , 12 View FIGURES 10–13 ); mentum quadrate, labial palpi well separated ( Fig. 22 View FIGURES 21–22 ); metaventrite short, entirely hydrofuge pubescent ( Figs. 8, 9 View FIGURES 6–9 ); subantarctic islands and islands near New Zealand...............................................................................
