Revision ofDurbadnusPasteels, 1954, with Notes on Other Afrotropical Blennocampinae and Allantinae (Hymenoptera: Symphyta: Tenthredinidae)

Abstract

Three species are included in this revision of the Afrotropical sawfly genus Durbadnus Pasteels, 1954: D. chubbi (Forsius, 1930), D. obscuripes (Forsius, 1931) comb. n. and D. taegeri sp. n. A new junior synonym of D. chubbi is Blennocampa bensoni Forsius, 1931 (syn. n. ). The genus Durbadnus is restricted to South Africa, with D. taegeri being the first recorded member of the Tenthredinidae in the winter-rainfall zone of western South Africa. A key is provided to the five Afrotropical genera of Blennocampinae (Aethiocampa, Distega, Durbadnus, Tesslinia and Trisodontophyes). Kivua Forsius, 1934 is transferred from the Blennocampinae to the Allantinae. New junior synonyms of Kivua are Bicrista Pasteels, 1949 (syn. n.), Tumura Pasteels, 1949 (syn. n.) and Urocerca Pasteels, 1949 (syn. n.). The following new combinations result: Kivua bicolor comb. n. (Bicrista bicolor Pasteels, 1949), Kivua acuticornis comb. n. (Erythraspides acuticornis Pasteels, 1953), Kivua afra comb. n. (Erythraspides afra Pasteels, 1953), Kivua cribrifrons comb. n. (Urocerca cribrifrons Pasteels, 1949), Kivua pallipes comb. n. (Urocerca pallipes Pasteels, 1949) and Kivua tenuis comb. n. (Urocerca tenuis Pasteels, 1949). The specific epithet luteiventris is preoccupied in Kivua by K. luteiventris Pasteels, 1949, so that new names are proposed for two further species group taxa transferred here to Kivua: Kivua violae nom. n. for Tumura luteiventris Pasteels, 1949 and Kivua cara nom. n. for Urocerca luteiventris Pasteels, 1949. Neacidiophora quadrifoveata Koch, 1998 is a junior synonym of Kivua incrassata Pasteels, 1949 (syn. n.).
