The genus Cryptofavognathus is represented with only two species: Cryptofavognathus anatolicus Doğan & Dönel and C. afyonensis (Koç & Akyol). The third species, Cryptofavognathus bellus sp. nov., was detected during a faunistic study on raphignathoid mites of Sansa Gorge (Türkiye) and described here. This paper also presents a current species list for the family Cryptognathidae Oudemans, with the following taxonomic recommendation in the genus Favognathus Luxton: Favognathus aegyptiaca (Fawzy, Khalil & Yassin) and Favognathus rosetta (Fawzy, Khalil & Yassin) described from Egypt should be considered species inquirendae due to their inadequate diagnostic characteristics and poor descriptions.

Three new species of eriophyoid mite from China are described and illustrated. They are Rhyncaphytoptus emeishanicus sp. nov. on Acer tataricum subsp. ginnala (Sapindaceae), Rhyncaphytoptus thysanolaenus sp. nov. on Thysanolaena latifolia (Poaceae), and Catarhinus haikouicus sp. nov. on Miscanthus floridulus (Poaceae). All three new eriophyoid mite species are vagrants causing no apparent symptom to their host plants.

The tomato red spider mite, Tetranychus evansi, a notorious crop pest, invaded New Zealand in 2020. In an effort to identify potential biological control agents for this species, we investigated the capabilities of four phytoseiid predators found in New Zealand—Amblyseius herbicolus, Amblyseius lentiginosus, Amblydromalus limonicus, and Neoseiulus californicus. For comparison, we also used the two-spotted spider mite, T. urticae, and the dried fruit mite, Carpoglyphus lactis, as prey for these predators. In our first experiment we monitored immature development and oviposition rate (over the first 5 days) of the phytoseiid predators when presented with the three prey species. While all four species of predators could develop and reproduce on the factitious (alternative and easily available) prey species C. lactis, they had limited success when feeding on T. evansi and T. urticae. Amblyseius herbicolus, A. lentiginosus, and Amblyd. limonicus were unable to reach adulthood when feeding on T. evansi and T. urticae in the presence of the protective webbing spun by the mites. While N. californicus matured when exposed to T. evansi reared on black nightshade leaves, it did not lay eggs—indicating potential limitations in prey suitability. In our second experiment, gravid females of all four predators failed to maintain their reproduction when provided with T. evansi in the presence of webbing. Neoseiulus californicus exhibited phenotypic plasticity in its developmental time, body size, and oviposition rate when feeding on the three prey species. This suggests that N. californicus has the flexibility to switch diets to survive during food scarcity, especially when their primary prey, T. urticae, is limited. This study is also the first to offer life history information about A. lentiginosus. Our findings underscore the difficulties of controlling T. evansi using phytoseiid predators and highlight the need for diversified pest management strategies, including the use of alternative insect predators or entomopathogenic fungi.
番茄红蜘蛛（Tetranychus evansi）是一种臭名昭著的农作物害虫，于 2020 年入侵新西兰。为了确定该物种的潜在生物控制剂，我们调查了在新西兰发现的四种植毛螨捕食者的能力--Amblyseius herbicolus、Amblyseius lentiginosus、Amblydromalus limonicus 和 Neoseiulus californicus。为了进行比较，我们还使用了双斑蜘蛛螨（T. urticae）和干果螨（Carpoglyphus lactis）作为这些捕食者的猎物。在第一个实验中，我们监测了植食性天敌在遇到这三种猎物时的未成熟发育情况和产卵率（头 5 天）。虽然所有四种捕食者都能在假性（可供选择且容易获得的）猎物 C. lactis 上发育和繁殖，但它们在捕食 T. evansi 和 T. urticae 时却很难成功。Amblyseius herbicolus、A. lentiginosus 和 Amblyd. limonicus 在取食有螨类编织的保护网的 T. evansi 和 T. urticae 时无法达到成年。虽然加州蛱蝶在接触到黑夜来香叶上饲养的 T. evansi 时会成熟，但它并不产卵--这表明猎物适宜性的潜在限制。在我们的第二个实验中，当有蛛网存在时，所有四种捕食者的怀孕雌性都无法维持繁殖。加州霓虹鳉在捕食三种猎物时，在发育时间、体型和产卵率方面都表现出了表型可塑性。这表明加州蛱蝶在食物匮乏时，尤其是当其主要猎物荨麻蝇数量有限时，可以灵活地转换食物以求得生存。这项研究也是首次提供有关A. lentiginosus的生活史信息。我们的研究结果凸显了使用植食性天敌控制 T. evansi 的困难，并强调了多元化害虫管理策略的必要性，包括使用替代性昆虫天敌或昆虫病原真菌。

The tick species that comprise the Amblyomma maculatum group (Acari: Ixodidae) are widely distributed in the Nearctic and Neotropical regions, ranging from the United States of America (USA) to Argentina. This group includes three species: Amblyomma maculatum, Amblyomma tigrinum, and Amblyomma triste, which parasitize a high number of vertebrates, including domestic mammals and humans, where they are the main vectors of Rickettsia parkeri s.s. The identification, distribution, and validity of the three species within the group have been controversial and continue to raise questions. Previous studies have mostly focused on the analysis of partial nuclear and mitochondrial genes, highlighting the need for new integrative analyses that contribute to clarifying their systematics and ecology. In this investigation, we obtained the first mitochondrial genome of A. triste (14,808 bp), which, upon comparison with the reported mitochondrial genomes of A. maculatum, exhibits a genetic distance of 4.2%, providing new evidence for the validity of the former species. The order, composition, and structure of the mitogenome of A. triste are consistent with the characteristics reported for most Metastriata including taxa within Amblyomma, that count with several mitochondrial genomes published in the last few years. The attributes of the mitogenomes, such as the absence of paralogs and a small genome, confirm the utility in studies involving complexes of cryptic species as it also serves as a robust tool for inferring phylogenies. Furthermore, we reported new molecular markers at the mitochondrial level which can be used in phylogenetic studies for other tick species, especially those with controversial or challenging taxonomy. We highlight the need of sequencing the mitochondrial genome of A. tigrinum, which is part of the A. maculatum group, as well as experimental crosses of populations from different places in the Americas to obtain additional evidence for species recognition.

The attributes of the mitogenomes, such as the absence of paralogs and a small genome, confirm the utility in studies involving complexes of cryptic species as it also serves as a robust tool for inferring phylogenies. Furthermore, we reported new molecular markers at the mitochondrial level which can be used in phylogenetic studies for other tick species, especially those with controversial or challenging taxonomy. We highlight the need of sequencing the mitochondrial genome of A. tigrinum, which is part of the A. maculatum group, as well as experimental crosses of populations from different places in the Americas to obtain additional evidence for species recognition.","PeriodicalId":51306,"journal":{"name":"Systematic and Applied Acarology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
