Description. The external anatomy of this species was thoroughly described by Gillogly (1965) as N. meridionalis . Male genitalia with anal sclerite possessing a shallow fossa for reception of tegmen ( Fig. 23 ), bearing a longitudinal sclerotized ridge across apical region of sclerite near apical margin, and numerous moderate to long straight setae originating from apex. Basal margin of the tegmen angled slightly anteriorly ( Fig. 27 ), nine long setae originating near base of median lobe fossa, with numerous short dense setae present from ventral to dorsal surface at apex. Median lobe with two slender median grooves ( Fig. 28 ). Ovipositor with gonocoxites long and slender, distinctly separate but approximate at base ( Fig. 39 ), bearing numerous scattered sensillae present on apical two-thirds, several long setae along lateral margin, and terminal appendages borne from large latero-apical pit, each terminal appendage bearing 3 long setae. Paraprocts subcylindrical with medial areas somewhat swollen ( Fig. 35 ), medial and basal borders moderately sclerotized.

New Distributional Records. Previously, L. brunneus was known from near Caviuna in Parana and Santa Catarina, Brazil, the Middle Rio Ucayali in Peru, and also near Sani Beni around Lima, Peru. Thus, the species was known from two areas, around the southwestern coast of Peru and southeastern Brazil. New records extend to the Esperito Santo province of Brazil, westward into Rondonia near the Bolivian and Peruvian border, into Paraguay, and also the Santa Cruz district of Bolivia. Therefore, L. brunneus occurs across South America from the Atlantic to Pacific coasts ( Fig. 44 ).
