Mesorhaga

Neotropical Mesorhaga

I have seen undescribed species from South America in collections, again in small numbers. Possibly the

genus is absent from the smaller Caribbean islands, as none were recorded from Dominica ( Robinson 1975),

nor have I seen the genus in collections from Hispaniola (Carnegie Museum, Pittsburgh). Naglis (2000) pro-

vided a key to Neotropical species and described two Brazilian species in detail.

Mesoamerican species are marked with an asterisk, and are treated in detail further in this paper. Acronyms of

repositories housing the primary types are listed in parentheses.
