Type Material
Type specimens came from banana shipments arrived at U.S. Quarentine ports (Charleston, South Carolina; Brownsville, Texas and New York, NY). Holotype and 3 paratypes at Museu de Zoologia da USP; 2 paratypes at National Museum of Natural History, Washington; 2 paratypes at Museum of Comparative Zoology, Harvard.
Etymology
