This is a large tropical genus with about 60 described species. There are 30 species of Metamasius  in Costa Rica and 29 (plus 1 questionable) in Panama with 24 shared between the two countries. The genus occurs from the southern United States to Argentina.

Herein I group all species that possess the plesiomorphic character state of some indication of a lateral line on the aedeagus. This includes the genera Paramasius  and Cyrtomasius  as recently treated by Vanin (1998). The two described species of Paramasius  are the only Dryophthoridae  known to have a partial lateral line (incomplete at base; see Vanin 1998, Figs. 10View FIGURES 7 - 14 and 27View FIGURES 25 - 28) whereas the lateral line of the one known Cyrtomasius  species is complete ( Vanin 1998, Fig. 32View FIGURES 29 ­ 32) as in all Metamasius  . Similarity in body characters other than form of the aedeagus suggests that both 'taxa' are derived from within Metamasius  and do not warrant distinct generic status.

Species of Metamasius  are associated generally with monocotyledons such as orchids ( Orchidaceae  ), bromeliads (Bromeliadaceae), palms ( Arecaceae  ), sugarcane (Graminae), and bananas ( Musaceae  ) ( Vaurie 1966). Adults of most species are diurnal. Immature stages were described by Anderson (1948).
