Spiroxys ankarafantsika, sp. nov. is described from Madagascar in two species of freshwater turtles, Pelusios castanoides and Pelomedusa subrufa. Spiroxys ankarafantsika differs from other species of the genus in having pseudolabial teeth only on the median lobes and no other cuticular prominences, a smooth cuticular collar, deirides as cervical minute spine-like projections, and a gubernaculum without tubes. This is the first record of a nominal species of the genus Spiroxys from the Ethiopian region. 相似文献

Goezia moraveci n. sp. is described from light microscope and scanning electron microscope studies of the specimens recovered from the freshwater fish Mastacembelus armatus from West Bengal, India. G. moraveci differs from other species of the genus in having a small body size, the excretory pore posterior to the level of the nerve-ring, a very short, wide intestinal caecum and a long ventricular appendage (ratio 1: 6–15), a different number and arrangement of caudal papillae, and cuticular spines surrounding the bases of the caudal papillae. This represents the first species of the genus from a piscine host in India. 相似文献

Two new extant species of the fossil genus Alavesia Waters & Arillo (A. brandbergensis sp.n. and A. daura sp.n. ) are described from the Brandberg Massif, Namibia. The genus is reassigned to the family Atelestidae (subfamily Atelestinae) on the basis of male terminalia (elongate gonocoxal apodemes, ventral apodemes, subapical surstylus), female terminalia (absence of tergum 10) and a three‐articled stylus. This is the first record of Atelestidae from the Afrotropical Region. A genus‐level phylogeny of the Atelestidae is resolved, in which Alavesia is the sister genus to the remaining genera of the Atelestinae. The biogeographic history of the genus is briefly discussed, as is the significance of this and other relict Diptera on the Brandberg. 相似文献

Summary
Neopolystoma kreffti n.sp. from the mouth and pharyngeal cavity ofEmydura krefftii (Pleurodira, Chelidae) in southern Queensland,N. macleayi n.sp. from the cloacal bursa, andN. australis n.sp. from the mouth and pharyngeal cavity ofEmydura sp. in New South Wales are described. The new species differ from other species of the genus mainly in the number and shape of the genital hooks. New locality records ofN. chelodinae fromChelodina longicollis and ofPolystomoides australiensis fromE. krefftii are given. ac]19821026 相似文献

Empruthotrema kearni n. sp. and Thaumatocotyle pseudodasybatis Hargis, 1955 (Monogenea: Monocotylidae) are reported from the nasal fossae of the spotted eagle ray, Aetobatus narinari Euphrasen, 1790, from Moreton Bay, Queensland, Australia. The discovery of E. kearni n. sp. is the first record of this genus from the Myliobatidae and a new geographical record for the genus. A comparison
of T. pseudodasybatis from Florida, USA and from Queensland, Australia revealed morphometrical and microhabitat differences. The discovery of T. pseudodasybatis in Australian waters is a new geographical record for this species. 相似文献

A new genus and species of freshwater monostiliferous hoplonemertean, Limnemertes poyangensis gen. et sp. nov., from Poyang Lake, People's Republic of China, is described and illustrated. The taxon is compared and contrasted with previously described freshwater hoplonemerteans. This is the fourth species of freshwater nemertean to be described from China and the first recorded from Poyang Lake. 相似文献

Zalophotrema atlanticum n. sp. from the liver of a striped dolphin, Stenella coeruleoalba (Meyen, 1833), stranded in the Canary Islands is described. This new species differs from the other Zalophotrema species in body dimensions and relative size and position of the suckers and cirrus-sac. This is the first record of a species of the genus Zalophotrema in the striped dolphin, and the Atlantic Ocean constitutes a new locality record for this genus. 相似文献

The genus Skidmorella Johnson, previously known only from the South Pacific islands, is discovered in Japan. The type species, Skidmorella magnifica Johnson, is confirmed from Japan as the first record of the species other than the type locality. In addition, two new species, Skidmorella amamiana sp. nov. and Skidmorella quadrisulucia sp. nov., are described from the Ryukyus, Japan. Phylogenetic relationships of the genus Skidmorella and its allies are discussed on the basis of their morphological characters. 相似文献

Landouria omphalostoma n. sp. is described from northern Yunnan, China. The new species is placed in the genus Landouria Godwin-Austen, 1918 based on the presence of tuberculated flagellum and swollen basal part in the bursa copulatrix, and on the absence of dart sacs and mucous glands. L. omphalostoma n. sp. is characterized by a horizontal aperture of the shell which is unique in the genus. This feature resembles those of only two other camaenid/bradybaenid taxa, species of the Chinese genus Pseudaspasita Möllendorff, 1902 and species of the Japanese genus Coelorus Pilsbry, 1900. This is the first verified record of the genus in China and the easternmost record of Landouria. This paper provides the taxonomic ground work for further studies of the repeated evolution of a horizontal aperture. 相似文献

Phloeocharis Mannerheim is the largest genus within the problematic rove beetle subfamily Phloeocharinae, with a single extinct and 44 recent species recorded from the Holarctic Region. Until now, the oldest fossil record of Phloeocharis was known from Late Cretaceous (Turonian) amber from New Jersey, USA. Here we describe 2Phloeocharis burmana n. sp. from mid-Cretaceous (Albian–Cenomanian) Kachin amber from northern Myanmar, as the earliest extinct species of this genus. Our finding also sheds light on the biogeography of Phloeocharis, since no recent or extinct species have so far been recorded from the Oriental Region. Furthermore, the discovery of 2P. burmana n. sp. extends the Mesozoic diversity of the phloeocharine rove beetles both taxonomically and morphologically, particularly from Kachin amber. 相似文献

Desmidothrips n.gen. is described from New Zealand, with walkerae n.sp. as type‐species. Aeolothrips inauditus Bianchi from New Caledonia is transferred to this new genus. Desmidothrips is related to the Australian genus Desmothrips, and is the only member of the Aeolothripidae native to New Zealand. 相似文献

The genus Stichillus in Japan is revised. Three species are recognized: S. japonicus (Matsumura), S. spinosus Liu and Chou and S. cylindratus sp. nov. Stichillus brunneicornis Beyer is excluded from the Japanese fauna. These Japanese species are described and keyed. The male genitalia and the female terminalia are illustrated. Some unique characters of the male genitalia in the genus are reported, and morphology of the male genitalia and the female terminalia is discussed. 相似文献

A new genus, Asiaontsira gen. nov., and two new species, A. cucphuongi sp. nov. (type species) and A. cantonica sp. nov., are described from tropical and subtropical areas of South‐East China and North Vietnam. This genus is compared to the closely related Australian Ontsirospathius Belokobylskij, Iqbal and Austin, 2004 as well as the similar and almost cosmopolitan genus Ontsira Cameron, 1900. A key to both species of Asiaontsira gen. nov. is provided. 相似文献
