Key to genus for Malaxa  and related groups examined in this work (males)

1. Forewings apically pointed ( Figs. 2 View Figure , 35 View Figure ), arched on leading margin (giving wings a spatulate appearance); anal tube of male simple (not bearing processes; Fig. 5 View Figure ) and opening of male pygofer without processes; recorded from Philippines............................................................................................... Malaxa acutipennis 

1’- Forewings apically rounded ( Figs. 36–37 View Figure ), leading margin straight; anal tube of male either simple (e.g., Fig. 14 View Figure ) or with 1–2 processes; opening of pygofer with processes of varying sorts (e.g., Figs. 13 View Figure , 25, 27 View Figure )............................... 2

2. Anal tube with 1–2 processes; opening of pygofer usually bearing two broad lamellate medioventral processes, between them a V-like emargination; recorded from China.......................................... Malaxa sensu Hou et al. 2013 

2’- Anal tube simple ( Fig. 14 View Figure ); opening of pygofer either with a small midventral forked process ( Figs. 13 View Figure , 25 View Figure , 41 View Figure ), or a broad, scoop-like projection plus a pair of lateral teeth ( Fig. 27 View Figure ); Neotropical........................................... 3

3. Antennae very long (exceeding mesonotum), segment I several times as long as broad ( Figs. 10, 12 View Figure ); pygofer bearing a midventral forked process ( Figs. 13 View Figure , 25 View Figure , 41 View Figure ); aedeagus caudally directed bearing poorly sclerotized terminal process ( Figs. 26 View Figure , 38 View Figure ); hind leg spinulation 5-7-5 or 5-6-5............................................................. Lamaxa  n. g.

3’- Antennae shorter, not exceeding mesonotum, segment I about 2x as long as wide and approximately 1/3 length of segment II ( Figs. 19–20 View Figure ); pygofer opening with broad, median scoop-like projection and pair of rounded lateral teeth ( Fig. 27 View Figure ); aedeagus robust and strongly downcurved ( Figs. 28 View Figure , 39 View Figure ); hind leg spinulation 5-6-4................................
