从油橄榄（Olea europaea L.）在西班牙，从该材料中饲养了一种在分类学上类似于安氏隐翅虫（Metaphycus anneckei Guerrieri）和Noyes的拟囊蜂（encyrtid）寄生蜂。西班牙Metaphycus nr. sp. anneckei和描述为M.居住在加州的安内克鸟。尽管在一些形态特征上存在差异，但产卵器长度、雄外生殖器形状和触角棒的形态特征可作为鉴别雌雄蛾的依据。anneckei居民到加州和西班牙的材料，这是后来命名为Metaphycus hageni Daane和卡尔塔吉罗内。为了确定形态学差异是否与生物学差异相对应，研究了加州丽金龟的繁殖和产卵行为。anneckei和西班牙M. Hageni被研究。两种类型的个体之间没有观察到交配，种间配对只产生雄性后代。安氏干蜱雌虫通过鳞腹侧产卵存款，从未观察到寄主取食;雌虫通过鳞片的背部产卵，并经常被寄主取食。集体生物学证据与形态学证据一致，表明M. anneckei和M. hageni是离散的物种。将最近在加州和西班牙采集的标本与早期在澳大利亚、加州、希腊、夏威夷、意大利、以色列、墨西哥和南非采集的标本进行比较。除希腊和西班牙材料外，所有检查的标本均为M。anneckei。我们讨论了这一新的信息的意义，生物防治，并提供了一个关键的分离这些和其他密切相关的黑鳞寄生蜂。
Parasitized black scale, Saissetia oleae, were collected from olives (Olea europaea L.) in Spain and from this material an encyrtid parasitoid was reared that is taxonomically similar to Metaphycus anneckei Guerrieri and Noyes. Differences were noted between the Spanish Metaphycus nr. sp. anneckei and material described as M. anneckei that is resident to California. Although dissimilar in few morphological characters, the ovipositor length and shape of the male genitalia and the antennal club of both sexes can be used to discriminate between M. anneckei resident to California and the Spanish material, which was subsequently named Metaphycus hageni Daane and Caltagirone. To determine if morphological differences correspond to biological differences, reproductive and oviposition behaviours of Californian M. anneckei and Spanish M. hageni were studied. Mating was not observed between individuals of the two types and only male progeny were produced in interspecific pairings. Metaphycus anneckei females deposit eggs through the scale's ventral side and were never observed to host feed, while M. hageni females oviposit through the scale's dorsum and frequently host fed. The collective biological evidence agrees with morphological evidence, indicating that M. anneckei and M. hageni are discrete species. Specimens from recent collections in California and Spain were compared with specimens from earlier collections (1910s to 1980s) in Australia, California, Greece, Hawaii, Italy, Israel, Mexico, and South Africa. With the exception of Greek and Spanish material, all specimens examined were M. anneckei. We discuss the significance of this new information with respect to biological control and provide a key to separate these and other closely related black scale parasitoids.
