Abstract

Aberrations involving the metasoma in Hymenoptera are well-documented, with one notable teratological case being the fusion of metasomal terga, named symphysomery. This aberration, characterized by the fusion of the second and third terga, has been observed in various species groups of Hedychridium, spanning from Southern Africa to Central Asia. Similar aberrations were noted in Prochridium Linsenmaier from Mongolia and Anachrysis Krombein from Southern Africa. The monotypic genus Oligogaster Soliman & Kimsey is distinguished by two visible metasomal terga. However, the sole specimen of Oligogaster kimseyae Soliman, the type species of the genus, is here considered an aberrant specimen affected by symphysomery, exhibiting the fusion of the second and third metasomal terga. Consequently, Oligogaster Soliman & Kimsey is here synonymized with Hedychridium Abeille de Perrin.

杜鹃黄蜂的新畸胎病例,以及 Oligogaster Soliman & Kimsey(膜翅目,蝶形花科)的异名。
膜翅目昆虫中涉及中躯干的畸变有大量文献记载,其中一个显著的畸变案例是中躯干畸变融合,这种畸变被命名为 "交叠畸变"(symphysomery)。这种畸变的特征是第二和第三畸变体融合,在从南部非洲到中亚的多个姬蜂物种群中都有观察到。在蒙古的 Prochridium Linsenmaier 和南部非洲的 Anachrysis Krombein 中也发现了类似的畸变。单型属 Oligogaster Soliman & Kimsey 是通过两个可见的元畸变来区分的。然而,Oligogaster kimseyae Soliman 的唯一标本(该属的模式种)在此被认为是受交叠现象影响的异常标本,表现出第二和第三元畸形的融合。因此,Oligogaster Soliman & Kimsey 在此与 Hedychridium Abeille de Perrin 同名。

期刊介绍: Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
