Neomalaxa flava Muir, 1918 - Brazil, Caribbean (Dominica, Puerto Rico, St. Lucia, Trinidad) Ecuador, Guyana, Panama, Venezuela.
Neomalaxa flava - Urochloa adspersa (Trin.) R. Webster (Dominican signalgrass) (as Brachiaria adspersa (Trin.) Parodi).
Economic Importance: Probably limited - not reported as a pest.
Very fragile, head quite barrow with respect to prothorax, with strongly narrowed frons (somewhat projected beyond eye) and long antennae (with dark lines on anterior margin of scape); green-ish in life. I've seen this species in long series, but seldom in good shape. It is possible that there are unrecorded species in this genus.
