The purpose of this application, under Article 75.5 of the Code, is to
designate a neotype for Belostoma ellipticum Latreille, 1833. This species has been
accepted by heteropterists since 1962, but it is actually a nomen dubium, since
Latreille designated neither types nor a type locality and provided little descriptive
information. Subsequent to Latreille, in the absence of a useful diagnosis, authors
referred specimens of several other taxonomically valid taxa to B. ellipticum.
Belostoma ellipticum sensu Lauck, 1962, however, is readily defined by the presence
of a pair of conspicuous notches along the lateral margins of the ventral diverticulum
of the phallus in ventral view, and it is this concept of the species that has gained
general acceptance. Fixation of a neotype displaying this feature, which cannot be
confirmed in any potentially syntypic Latreille specimen of the subspinosum group in
Carreno’s collection at the Museo Nacional de Ciencias Naturales, Madrid, will
facilitate retention of B. ellipticum as a valid species name.
