摘要

摘要不均等溢蚊和间断溢蚊是狐螨科常见的体外寄生虫。Kohls(1940)认为在华盛顿州东南部和俄勒冈州、爱达荷州中南部和犹他州的同域地区存在这些亚种的杂交。Kohl的结论是基于传统形态学特征的“clasper”(基粒和端粒)和后胫骨外表面的毛分类学。这些形态特征,以及aedeagus的形态特征,直到现在还没有被批判性地研究过。对这两个分类群的结构进行了研究,发现有几个一致的结构将这两个密切相关的物种分开。虽然同域居群之间有明显差异,但外周居群之间是一致的,但中背叶和硬化内管顶端的变化不大。这些性状是稳定的,几乎没有变化,它们的结构似乎有足够的不同,潜在地抑制了通常发生在亚种相遇处的杂交。这些性状是有效的区分性状,即使两个物种的雄性同时出现在同一寄主上。这些新认识的aedeagus的静态特征被说明。胫骨后外侧表面是区分两种雌性的最有效标准,尽管这不能确定任何程度的确定性。在此,不相等的溢音中断被提升为完全特定状态(溢音中断)(修订状态)。表1提供了一个资源的各种裂片和过程的端粒附属物的超科雄鸟。表2和表3总结了文献中现有的宿主和分布记录。

Elevation of Spilopsyllus inaequalis interrupta (Jordan, 1925) (Insecta, Siphonaptera) to Full Specific Status Based on Morphology and Geographical Distribution
ABSTRACT Spilopsyllus inaequalis inaequalis and Spilopsyllus inaequalis interrupta are common ectoparasites of species of Leporidae. Kohls (1940) suggested that there are intergrades of these subspecies in sympatric areas of southeastern Washington and Oregon, south central Idaho, and Utah. Kohl's conclusions were based on traditional morphological features of the “clasper” (basimere and telomere) and chaetotaxy of the outer surface of the hind tibia. These morphological features, and that of the aedeagus, have never been critically studied until now. The aedeagi of both taxa were examined and several consistent structures separate these closely allied species. The median dorsal lobe and apex of the sclerotized inner tube show little variation, although they are distinctly different among the sympatric populations and are consistent in peripheral populations. These characters are stable with little variation and their structure appears to be sufficiently different to potentially inhibit interbreeding that typically occurs where subspecies meet. These characters are valid distinguishing characters even when males of both species occur simultaneously on the same host. These newly reognized static characters of the aedeagus are illustrated. The lateral surface of the hind tibia is the most valid criterion for separation of females of the two species, although this cannot be determined with any degree of certainty. Spilopsyllus inaequalis interrupta is herein elevated to full specific status (Spilopsyllus interruptus) (Amended Status). Table 1 provides a resource for the terminology of various lobes and processes of the telomeric appendages of males of the superfamily Pulicoidea. Host and distribution records available in the literature are summarized in Tables 2 and 3.

期刊介绍: Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel. Carnegie Museum staff and research associates receive publication priority, but others are encouraged to submit papers, especially those manuscripts explicitly based on the Carnegie collection.
