ABSTRACT Xestoblatta Hebard, 1916 is revisited, with description of X. urucuana sp. nov. from northern Brazil. Additionally the hitherto known species X. amaparica Rocha e Silva Albuquerque & Gurney, 1962, X. surinamensis Bruijning, 1959 and X. vera Rocha e Silva Albuquerque & Fraga, 1975, are redescribed. Information on the genitalia of the males is also provided. All the species are included in the Xestoblatta surinamensis species group and the placement of X. jygautieri Grandcolas, 1992 in this group discussed. To facilitate species identification, we provide a key to the species of the X. surinamensis group, charac terized by the subgenital plate with left style (ventral view) about two to five times larger than right style; right paraproct (dorsal view) with three lobes, one with a spiny projection, and median sclerite slender and lanceolate. |
