Background The European species of the genus Tetrastichus (Insecta, Hymenoptera, Eulophidae, Tetrastichinae) are revised with 93 species, including 50 species described as new. The revision was conducted using an integrative taxonomic approach, based on DNA barcoding in combination with morphological characters. The Tetrastichinae are a biologically diverse and species-rich group of parasitoid wasps with numerous complexes of morphologically often very similar species that attack a wide range of hosts in over 100 insect families in 10 different orders. The genus Tetrastichus is, with almost 500 described species, the third largest genus of Tetrastichinae. Although biological information is lacking for most species, current data indicate that Tetrastichus species are gregarious koinobiont endoparasitoids developing on juvenile stages of mainly holometabolous insects. Due to their host specificity, several species of Tetrastichus are used as biological control agents. New information The European species of Tetrastichus Haliday (Hymenoptera: Eulophidae) are revised using a combination of externo-morphological and DNA barcoding data. This is the first integrative approach for any of the large genera of the Tetrastichinae. A total of 93 species are included, of which 50 are described as new: T. agonus sp. n., T. antonjanssoni sp. n., T. argei sp. n., T. argutus sp. n., T. asilis sp. n., T. ballotus sp. n., T. bledius sp. n., T. broncus sp. n., T. calcarius sp. n., T. calmius sp. n., T. clisius sp. n., T. cosidis sp. n., T. cumulus sp. n., T. cyprus sp. n., T. delvarei sp. n., T. doczkali sp. n., T. elanus sp. n., T. elodius sp. n., T. ennis sp. n., T. enodis sp. n., T. erinus sp. n., T. evexus sp. n., T. fadus sp. n., T. fenrisi sp. n., T. flaccius sp. n., T. gredius sp. n., T. iasi sp. n., T. illydris sp. n., T. incanus sp. n., T. inscitus sp. n., T. intruitus sp. n., T. johnnoyesi sp. n., T. lacustrinus sp. n., T. ladrus sp. n., T. lanius sp. n., T. lazius sp. n., T. lixalius sp. n., T. lycus sp. n., T. marcusgrahami sp. n., T. minius sp. n., T. mixtus sp. n., T. nataliedaleskeyae sp. n., T. nymphae sp. n., T. pixius sp. n., T. scardiae sp. n., T. splendens sp. n., T. sti sp. n., T. suecus sp. n., T. tacitus sp. n. and T. tartus sp. n. Two keys for the identification of species are presented, one for females and one for males. Based on DNA barcode sequences for 70 of the species, a Maximum Likelihood tree to assess phylogenetic relationships within the genus is presented. These 70 species are also characterised by a combination of CO1 and morphological data. The remaining 23 species, without a DNA barcode, are characterised by morphological data. Using a combination of data from the morphology and CO1 or morphological data only, the species are separated into three species groups (clito-, hylotomarum-, murcia-groups) with 41 unplaced species outside these groups. Hosts are known for 27 of the species and they are gregarious, koinobiont endoparasitoids on a wide range of immature stages of holometabolous insects and appear to be very host specific. The first host record for Lepidoptera (Tineidae) in Europe is included.

使用综合分类法对欧洲海利达属(膜翅目:Eulophidae)物种的修订

背景 欧洲的 Tetrastichus 属(Insecta、Hymenoptera、Eulophidae、Tetrastichinae)被修订为 93 个物种,其中 50 个被描述为新物种。修订是使用综合分类学方法进行的,基于 DNA 条形码与形态特征相结合。Tetrastichinae 是一个生物多样性和物种丰富的寄生蜂群,具有许多形态学上通常非常相似的物种的复合体,它们攻击 10 个不同目的 100 多个昆虫科的广泛宿主。Tetrastichus 属,有近 500 个被描述的物种,是 Tetrastichinae 的第三大属。尽管大多数物种都缺乏生物学信息,目前的数据表明,Tetraastichus 物种是群居的 koinobiont 内寄生蜂,主要发育在全代谢昆虫的幼年阶段。由于它们的宿主特异性,几种 Tetrastichus 被用作生物控制剂。新信息 结合外部形态学和 DNA 条形码数据对欧洲的 Tetrastichus Haliday 物种(膜翅目:Eulophidae)进行了修订。这是对任何大的 Tetrastichinae 属的第一个综合方法。总共包括 93 个物种,其中 50 个被描述为新物种:T. agonus sp。n.,T. antonjanssoni sp。n.,T. argei sp。n., T. argutus sp. n., T. asilis sp. n., T. ballotus sp. n.,T.bledius sp。n.,T. broncus sp。n.,T. calcarius sp。n.,T.calcius sp。n.,T. clisius sp。n.,T. cosidis sp。n., T. cumulus sp. n., T. cyprus sp. n.,T. 德尔瓦雷湾 n.,T. doczkali sp。n.,T. elanus sp。n.,T. elodius sp。n., T. ennis sp. n.,T. enodis sp。n.,T. erinus sp。n.,T. evexus sp。n.,T. fadus sp。n.,T. fenrisi sp。n.,T. flaccius sp。n.,T. gredius sp。n.,T. iasi sp。n.,T. illydris sp。n.,T. incanus sp。n.,T. inscitus sp。n.,T. intruitus sp。n.,T. johnnoyesi sp。n.,T. lacustrinus sp。n.,T. ladrus sp。n.,T. lanius sp。n., T. lazius sp. n.,T. lixalius sp。n.,T. lycus sp。n.,T. marcusgrahami sp。n., T. minius sp. n.,T. mixtus sp。n.,T. nataliedaleskeyae sp。n.,T. nymphae sp。n.,T. pixius sp。n.,T. Scardiae sp。n.,芨芨草 sp。n., T. sti sp. n.,T. suecus sp。n.,T. tacitus sp。n. 和 T. tartus sp。n. 提供了两个用于识别物种的关键,一个用于雌性,一个用于雄性。基于 70 个物种的 DNA 条形码序列,提出了评估该属内系统发育关系的最大似然树。这 70 个物种的特征还在于 CO1 和形态数据的组合。其余 23 个物种,没有 DNA 条形码,以形态学数据为特征。仅使用形态学和 CO1 数据或形态学数据的组合,将物种分为三个物种组(clito-、hylotomarum-、murcia-组),其中 41 个未放置在这些组之外的物种。已知有 27 个物种的宿主,它们是群居的 koinobiont 内寄生蜂,存在于各种全代谢昆虫的未成熟阶段,并且似乎具有很强的宿主特异性。包括欧洲第一个鳞翅目(Tineidae)宿主记录。这 70 个物种的特征还在于 CO1 和形态数据的组合。其余 23 个物种,没有 DNA 条形码,以形态学数据为特征。仅使用形态学和 CO1 数据或形态学数据的组合,将物种分为三个物种组(clito-、hylotomarum-、murcia-组),其中 41 个未放置在这些组之外的物种。已知有 27 个物种的宿主,它们是群居的 koinobiont 内寄生蜂,存在于各种全代谢昆虫的未成熟阶段,并且似乎具有很强的宿主特异性。包括欧洲第一个鳞翅目(Tineidae)宿主记录。这 70 个物种的特征还在于 CO1 和形态数据的组合。其余 23 个物种,没有 DNA 条形码,以形态学数据为特征。仅使用形态学和 CO1 数据或形态学数据的组合,将物种分为三个物种组(clito-、hylotomarum-、murcia-组),其中 41 个未放置在这些组之外的物种。已知有 27 个物种的宿主,它们是群居的 koinobiont 内寄生蜂,存在于各种全代谢昆虫的未成熟阶段,并且似乎具有很强的宿主特异性。包括欧洲第一个鳞翅目(Tineidae)宿主记录。仅使用形态学和 CO1 数据或形态学数据的组合,将物种分为三个物种组(clito-、hylotomarum-、murcia-组),其中 41 个未放置在这些组之外的物种。已知有 27 个物种的宿主,它们是群居的 koinobiont 内寄生蜂,存在于各种全代谢昆虫的未成熟阶段,并且似乎具有很强的宿主特异性。包括欧洲第一个鳞翅目(Tineidae)宿主记录。仅使用形态学和 CO1 数据或形态学数据的组合,将物种分为三个物种组(clito-、hylotomarum-、murcia-组),其中 41 个未放置在这些组之外的物种。已知有 27 个物种的宿主,它们是群居的 koinobiont 内寄生蜂,存在于各种全代谢昆虫的未成熟阶段,并且似乎具有很强的宿主特异性。包括欧洲第一个鳞翅目(Tineidae)宿主记录。
