A morphology-based phylogenetic analysis of the 24 species of Isobactrus (Acari: Halacaridae) demonstrated three major monophyletic groups supported by synapomorphies. Each group is geographically distinct being tropical Pacific, North Atlantic and Holarctic. Character optimization indicates some evolutionary tendencies of character transformation. Reduction of idiosomal lateral setation, loss of setae on the genu and the addition of female subgenital setae are postulated synapomorphies congruent throughout the tropical lineage. Similarly, setal addition on the telofemur occurred in the North Atlantic lineage, while reduction of genital area sclerotization is recognized in a northern phyletic group. 相似文献

Amongst the vagile epifauna on the mangrove trees Avicennia marina and Rhizophora stylosa, Acari numerically play an important role, contributing 20-75% of the fauna. The two major groups are the prostigmatids and oribatids. Amongst the prostigmatid mites, halacarids are regularly present from the upper littoral fringe, inundated only at very high tide, to the permanently wet substrata adjacent to tide pools. Oribatids are most abundant in permanently wet substrata and often dominate the mite fauna. Five halacarid species, regularly found amongst the epibios on mangroves, are described, Isobactrus australiensis n. sp., Rhombognathus ocularis n. sp., Agauopsis dasyderma n. sp., Copidognathus lutarius n. sp. and C. piger n. sp. Isobactrus australiensis often is the only mite in the upper zone not reached by every high water. 相似文献

This is the first record of the subfamily Rhombognathinae on the Brazilian coast. A new species is described, Rhombognathus levigatoides sp. nov., which shares most diagnostic features with R. levigatus Bartsch, 2000, but differs from it by measurements of ds‐1, dorsal plates, and spermatophorotype. A detailed account is provided of its spermiogenesis and sperm cell morphology. Rhombognathus sperm cells show features that should be regarded as probable plesiomorphies if contrasted with those found in the other two halacarid spermatozoa studied until now, Halacarellus thomasi and Thalassarachna basteri, such as the almost unmodified mitochondria, type of nuclear condensation similar to that observed in most Actinedida mites, complete acrosomal complex, and presence of a single kind of globular secretion. 相似文献

During the last half century, the generic names Halacarellus and Thalassarachna have been used in parallel. The author now proposes to regard them as two separate genera distinguished by the number of dorsal setae on tarsi I and II. Halacarellus s. str., with Halacarus balticus Lohmann as the type species, has three dorsal setae on both tarsi, whilst Thalassarachna s. str., with the type species Acarus basteri Johnston, has five or more dorsal setae on tarsus I and four or more on tarsus II. The number of setae on tarsi I and II is expected to be a valid generic character. Species of the genus Halacarellus s. str. are recorded from both the northern and southern hemispheres; the North Atlantic species are distinct from those in the southern oceans. Thalassarachna s. str. is known only from the North. 相似文献

Three new species of Copidognathinae (Acari: Halacaridae) are described from the eastern coast of southern Africa (Mozambique; South Africa: Eastern Cape and KwaZulu-Natal). Copidognathus caloglossae sp. nov. and Acarothrix umgenica sp. nov. were collected in mangrove habitats, whereas Copidognathus xaixaiensis sp. nov. was collected on a rocky shore. Acarothrix umgenica represents the first record of the genus Acarothrix Bartsch, 1990 from the African continent. 相似文献

Lake, which is located in south-west Turkey, are described here. The morphological features of the species are compared with those of the similar species Arrenurus claviger Konike, 1882 and Arrenurus nodosus (Koenike, 1896). 相似文献

We characterised the mite fauna associated with a subtidal population of Laminaria ochroleuca in the Cantabrian Sea during a 4-year study. We found 2780 individuals belonging to 35 species. The mite assemblage comprised both north Atlantic and Mediterranean species, as usually reported from the Lusitanian region. The most abundant and diverse subfamily was Copidognathinae, followed by Halacarinae and Lohmannellinae. The greatest abundance of mites was detected on kelp holdfasts, not only strictly phytal mites were found but also interstitial mites or those associated with other macrofauna. Such a distribution could be explained by the high diversity and heterogeneity of microhabitats provided by holdfasts. Mite abundance fluctuated during the 4 years of the study. However, the lowest abundance was detected during the last year of sampling. During that year, the studied algal population suffered a severe decay leaving only degenerating holdfasts attached to the substrate, which could explain the decrease in mite numbers. 相似文献

Their interspecific relationships are discussed and two new species-groups, T. strasseri and T. vornatscheri, are defined. A key to the known adult species of the genus Troglocheles Zacharda is given. Phylogenetic and evolutionary relationships among the known talus- and cave-dwelling species of this genus are briefly outlined, including the possibilities of sympatric versus allopatric speciation. 相似文献

Eustigmaeus floridensis sp. nov. is described and illustrated based on female specimens collected from citrus trees in Florida, USA. The new species is closely related to Eustigmaeus arcuata, Eustigmaeus segnis and Eustigmaeus microsegnis, all known to occur in Florida. Eustigmaeus floridensis sp. nov. can be distinguished by larger dimples associated with setae sce, d2 and e1 containing at least four or more vacuoles centrally; dorsal body setae broadly lanceolate and feather-like, except c2, which is slender; anogenital area with striae and one pair of serrated aggenital (ag1) and three pairs of serrated pseudanal (ps1?3) setae. A key to the Eustigmaeus species known to occur across USA is also provided. 相似文献

Three new species of oribatid mites belonging to the genus Liebstadia are described from Mongolia. The new species are characterized by the poorly developed pteromorphae; the club-shaped head of the sensilli; the absence of the dorsosejugal suture; the dorso-ventral thickness, and the length and arrangement of notogastral setae. In addition, L. similis (Michael, 1888) is redescribed and recorded for the first time in Mongolia. Protoribates serratomarginatus Mahunka, 1983 is synonymized with L. similis. A key to the known species of the genus Liebstadia is given. 相似文献
