Abstract

The genera Colpixys and Xiphentedon are revised. Both genera are of Afrotropical distribution and are very similar to Entedon, but distinguished by a median strip or furrow on the propodeum replacing the median carina of Entedon. The genus Xiphentedon is characterized by the complete lateral propodeal sulci delimiting convex submedian areas, prosternum with a flange, axillula with indentate projection, and densely hairy central mesopectus. The subgenus Cederholmia Gumovsky, 1997 of Entedon is considered a junior synonym of Xiphentedon, so two of its species are moved to the genus as X. halli (Gumovsky, 1997) comb. nov. and X. danielssoni (Gumovsky, 1997) comb. nov. The genus Colpixys is characterized by the lack of characters of Xiphentedon, but also by the broadly sculptured propodeum with the deep median furrow delimited laterally by two sinuous margins. Three (one new) species are recognized in Colpixys and sixteen (thirteen new) species allocated to three groups (kayovei, danielssoni and forceps), are assigned to Xiphentedon. The new species are: Colpixys eburnus sp. nov. from Ivory Coast and the Republic of South Africa (RSA), Xiphentedon neserorum sp. nov. from RSA, X. simoni sp. nov. from Tanzania, X. dewittei sp. nov. and X. musimba sp. nov. from the Democratic Republic of the Congo (DRC), X. jeanyvesi sp. nov. from Tanzania, the Central African Republic (CAR) and RSA, X. wieringai sp. nov. from Gabon and Ivory Coast, X. kivuensis sp. nov. from DRC, X. palabora sp. nov. from RSA, X. sangha sp. nov. from CAR, X. nimba sp. nov. from Guinea, X. forceps sp. nov. from Ivory Coast, Benin and RSA, X. gerardi sp. nov. from Benin, DRC and RSA, and X. acutigena sp. nov. from Ivory Coast, DRC, Tanzania and RSA. Morphological peculiarities and possible relationships of Colpixys, Xiphentedon, Entedon and some other genera, are discussed.

修订Xiphentedon Risbec, 1957和Colpixys Waterston, 1916(膜翅目，蜂科)，附非洲热带新种记述

修订了Colpixys属和Xiphentedon属。这两个属都是非洲热带分布，与Entedon非常相似，但区别在于proproder上的中间条或沟取代了Entedon的中间隆。刺齿兽属的特征是:完整的外侧颏沟划分凸的下正中区，前骨有凸缘，腋窝有凹痕突出，中部中直肌有浓密的毛。Entedon的Cederholmia Gumovsky(1997)亚属被认为是Xiphentedon的初级同义词，因此其两个种被移到X. halli (Gumovsky, 1997) comb属中。11 .和X. danielssoni (Gumovsky, 1997)梳理。11 . Colpixys属的特点是缺乏Xiphentedon的特征，但也具有宽雕刻的proprod，其深的中间沟被两个弯曲的边缘横向分隔。在Colpixys中鉴定出3种(1新种)，在Xiphentedon中鉴定出16种(13新种)，分属3个类群(kayovei、danielssoni和forceps)。这些新物种是:Colpixys eburnus sp. 11月从象牙海岸和南非共和国(RSA), Xiphentedon neserorum sp. 11月从RSA, x西摩尼sp. 11月来自坦桑尼亚,x dewittei sp. 11月和x musimba sp. 11月从刚果民主共和国(DRC), x jeanyvesi sp. 11月来自坦桑尼亚,中非共和国(汽车)和RSA, x wieringai sp. 11月从加蓬和象牙海岸,x kivuensis sp. 11月从刚果民主共和国,x palabora sp. 11月从RSA, x僧伽sp. 11月从汽车,来自几内亚的X. nimba，来自科特迪瓦、贝宁和RSA的X. forcres，来自贝宁、刚果民主共和国和RSA的X. gerardi，以及来自科特迪瓦、刚果民主共和国、坦桑尼亚和RSA的X. acutigena。讨论了Colpixys、Xiphentedon、enttedon等属的形态特征及其可能的亲缘关系。

期刊介绍： EJT is a fully refereed, international, fully electronic Open Access journal in descriptive taxonomy, covering subjects in zoology, entomology, botany (in its broadest sense), and palaeontology. EJT-papers must be original and adhere to high scientific (content) and technical (language, artwork, etc.) standards. Manuscripts that are clearly substandard in either of these categories will not be sent out for review. EJT is supported by a consortium of European Natural History Institutes, but its scope is global. Both authorship and geographical region of study need not be European. Authors are, however, strongly encouraged to involve European Natural History collections by consulting material or by depositing specimens (e.g. types and figured material) related to their published paper in the collection of a European Natural History Institute.
