The correct name of the neotropical soybean bug (Hemiptera: Alydidae)

Abstract

Neotropical Entomology 36(2): 320-321 (2007) O Nome Correto do Percevejo Neotropical da Soja (Hemiptera: Alydidae) RESUMO -Uma espécie de Neomegalotomus é praga ocasional de soja [Glycine max (L.) Merrill] na Região Neotropical, incluindo o Brasil. Essa espécie era conhecida como Neomegalotomus parvus (Westwood); entretanto, a descoberta da espécie tipo de uma outra espécie, descrita anteriormente, requer que o nome seja trocado para Neomegalotomus simplex (Westwood), o que o torna o nome correto para essa praga da soja. PALAVRAS-CHAVE: Espécie tipo, Neomegalotomus, Glycine maxABSTRACT -A species of Neomegalotomus is an occasional pest of soybean [Glycine max (L.) Merrill] in the neotropics, including in Brazil. It was known as Neomegalotomus parvus (Westwood); but the discovery of the type specimen of a species described earlier requires that the name be changed to Neomegalotomus simplex (Westwood), which becomes the correct name for the soybean pest.

A Revision of Neomegalotomus (Hemiptera: Alydidae)

“…Of the Alydus species described by Westwood and now included in Neomegalotomus, Alydus simplex has page priority (p. 18) over all the others, including both Neomegalotomus parvus (Westwood) (p. 19) and N. rufi pes (Westwood) (p. 19,directly following N. parvus). However, page priority lacks nomenclatorial force, and it alone cannot determine the type of a genus - Schaefer (2007) notwithstanding. Based on arguments presented elsewhere (Nemésio 2007), it is clear that Neomegalotomus parvus (Westwood) (Figs.…”

“…Based on arguments presented elsewhere (Nemésio 2007), it is clear that Neomegalotomus parvus (Westwood) (Figs. 1, 2) is the type of the genus; it is equally clear that the position taken by Schaefer (2007) is wrong.…”

Attractant Pheromone of the Neotropical SpeciesNeomegalotomus parvus(Westwood) (Heteroptera: Alydidae)

“…As other alydines, N. parvus is an oligophagous bug that feeds on immature seeds of legumes [1,2]. The taxonomic status of Neotropical alydine bugs was reviewed by Schaefer and Panizzi [3], Schaffner and Schaefer [4], Schaefer [5], and Schaefer and Ahmad [6]. From these works, Neotropical species formerly classified in the genus Megalotomus are now grouped in the genus Neomegalotomus, and South American species of Neomegalotomus were synonymized as N. parvus.…”
