Abstract

Egriodes dollmani Marshall and E. septentrionalis Colonnelli have been collected in numbers on Gymnosporia senegalensis trees in Ethiopia. This is the first record of a host of the genus Egriodes, endemic to Africa. The weevils occurred mostly on the buds of the tree at the beginning of blossom in December. Egriodes dollmani and E. alticollis Marshall, apparently very similar to E. septentrionalis, were collected together also in Zimbabwe by Sir G.A.K. Marshall; E. dollmani and E. alticollis were collected together in two localities in Namibia by the Late Ch.W. O’Brien, L.B. O’Brien, and G.B. Marshall. Egriodes loisae Korotyaev, sp. n., is described from Namibia where it was the only species of this genus found near Grootfontein. Taken the broad range of Gymnosporia senegalensis, association of all the listed species with this plant looks probable and calls for the further search of Egriodes on it in other regions of Africa, southern Middle East, South and South-East Asia.

论非洲象鼻虫属 Egriodes Marshall（鞘翅目，虫科：Ceutorhynchitae）的寄主植物及其分布

摘要在埃塞俄比亚的Gymnosporia senegalensis树上采集到了大量的Egriodes dollmani Marshall和E.这是非洲特有的 Egriodes 属宿主的首次记录。象鼻虫主要出现在 12 月开花初期的树芽上。Egriodes dollmani 和 E. alticollis Marshall，显然与 E. septentrionalis 非常相似，也是由 G.A.K. Marshall 爵士在津巴布韦一起采集到的；E. dollmani 和 E. alticollis 是由已故的 Ch.W. O'Brien、L.B. O'Brien 和 G.B. Marshall 在纳米比亚的两个地方一起采集到的。Egriodes loisae Korotyaev，sp. n.，描述自纳米比亚，它是在 Grootfontein 附近发现的该属的唯一物种。考虑到 Gymnosporia senegalensis 的分布范围很广，所有列出的种都可能与这种植物有关，因此需要在非洲其他地区、中东南部、南亚和东南亚进一步寻找 Egriodes。
