STUDIES ON THE FAUNA OF SURINAME AND OTHER GUYANAS: No. 4. The Blattidae of Surinam by C.F.A. Bruijning (Rijksmuseum van Natuurlijke Historie, Leiden) In the fair of earliest papers on neotropical Blattidae a number from Surinam specimens 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 secured paper was mainly by DR. D. C. GEIJSKES between 1938and 1955. His extensive travels bothin the coastal area and far into the interior of Surinam enabled him to collect all over the country. A — large and important part of his material was collected in collaboration with Drs. P. CREUTZBERG —• during the "Suriname- Expeditie" (1948-1949), initiated by the "Foundation for Scientific Reseach in Surinam and the Netherlands Antilles". Five regions in and coastal of the savannah area were explored: (/) a track 21 miles from Mungo Tapu (Moengotapoe) to the coast near the Wia Wia bank, in which numerous swamps had to be crossed; in (2) a coastal area Coronie; (3) a savannah near the Tibiti River and Zan- (tributary of the Coppename River); a savannah near derij II. The last journey (4) included the lower Marowijne River and the Nassau Mountains. In of Surinam is figure 1 a map given, showing localities and expedition routes where material studied in the present paper was collected. X ) DE GEER had a correspondent in Surinam named ROLANDER, from whom he received much material. SHELLFORD Ent. Soc. Lond. surmises {Trans. 1907, p. 457) that DE GEER lent some specimens in his collection to LINNAEUS for description. 2 Fig. 1.

In addition to Dr. GEIJSKES' series — here comprising all those samples without indication of collector — a small number of Surinam specimens from the Leiden and Amsterdam museums have also been examined. The names of the other collectors are the author's abbreviated with Br. always mentioned, e.g. name No lists of for the synonyms are given cosmopolitan species. As be the material studied with was to expected, agrees closely the series reported by HEBARD (1921, 1926), from French and British Guiana. The discusses 335 78 present paper specimens, representing species, 6 of which are described as new (see table 1). The species previously reported from Surinam, French, and British Guiana, but not represented in this material, have been added in order to complete the list of species known from the Guianas. The new species described here are: Buboblatta geijskesi, Xesto- blatta surinamensis, Euphyllodromia marowijnensis, Doradoblatta coppenamensis, Anaplecta pygmaea and Anaplecta guianae. 6 I am much indebted to DR. GEIJSKES, who made his large series available for of Blattidae, including some new and rare species, study. BLABERINAE Blaberus Serville 1831 Blaberus Ann. Sci. Nat. 37.

The male genitalia present far more reliable characters, and are very in the of this HEBARD had important taxonomy genus. (1917, p. 201) already pointed to the fact, but PRINCIS (1946) was the first author to use these characters in the of BLABERUS. He systematically classifying species distinguishes two groups, viz. the giganteus group and the atropos group. In the first group the top of the is teeth of the uniform penis curved upwards and the preputium are quite (fig.3 ). In second the has and is not while the group penis (dorsally only) a ridge, curved, teeth of the the preputium greatly vary in form, those on the extreme left being stout and blunt at the and of chitinous which apex forming groups larger processes are rounded distad (PRINCIS, I.e. "Hocker") (fig. 2). The of of the is still synonymy some species a problem. Blaberus atropos (Stoll) Fig. 2 Blatta STOLL, 1813, Blatt., 4, 2d 8. atropos Repr. Spectr. p. pi. fig. Nouv.
