Discussion. This is the largest known species of Neomacrocoris. It was reported as 15 mm and is known from only Belgian Congo ( Poisson 1948). There has been nothing in the literature about this species since the original description except for its listing in the La Rivers catalog of Naucoridae (La Rivers 1971). Poisson deposited two female specimens with identical label data (Fig. 17) in the Museum du Congo, now the Royal Museum of Central Africa in Tervuren, Belgium. Although both of these specimens were labeled “ TYPE ”, they are actually syntypes because a type specimen was not designated in the original description. To create taxonomic stability, we designated one specimen as a lectotype and labeled the other a paralectotype. A photograph of the dorsal surface (Fig. 16) and line drawing of the posterior abdominal sterna, including the subgenital plate (Fig. 18), of the lectotype are provided here. The male of this species is unknown.

Diagnosis. As the largest known species in the genus, size can be used with some degree of certainty. The female subgenital plate has mid-lateral projections, which are less produced than those of N. vuga . Because only females are known, male structures are not available for inclusion in the diagnosis.
