In the earliest papers on neotropical Blattidae a fair number of specimens from Surinam were recorded (LINNAEUS, DE GEER ¹), DE SAUSSURE, BRUNNER). But in the period from the beginning of this century up to now only a few scattered reports of Blattidae from that region have appeared in the literature of the subject. The present article will be the first to deal exclusively with Surinam species. The material dealt with in this paper was mainly secured by DR. D. C. GEIJSKES between 1938 and 1955. His extensive travels both in the coastal area and far into the interior of Surinam enabled him to collect all over the country.
