New taxa of the subfamily Phaneropterinae (Orthoptera: Tettigoniidae) from Africa: the tribes Otiaphysini and Preussiini

Abstract

Te new material on the following African genera of the subfamily Phaneropterinae is considered: Drepanophyllum Karsch, 1890 and Tetraconcha Karsch, 1890 belonging to the tribe Otiaphysini; Enochletica Karsch, 1896 and Weissenbornia Karsch, 1888 belonging to the tribe Preussiini. Four new species and two new subspecies are described: Drepanophyllum irisovi sp. n. (Cameroon), Drepanophyllum corrosifolium ugandense subsp. n. (Uganda), Tetraconcha bicolor sp. n. (Uganda), Tetraconcha unicolor sp. n. (Uganda), Enochletica simulata sp. n. (Uganda), and Weissenbornia praestantissima aurea subsp. n. (Uganda). All these species and subspecies are distinguished from each other and from all other representatives of the genera studied by the structure and colouration of their tegmina, as well as by some features of the stridulatory vein teeth, the shape of the male cerci and/or the structure of the male genital plate.
