Four new species, Phyllomyza kanmiyai sp. nov., P. amamiensis sp. nov., P. proceripalpis sp. nov. and P. japonica sp. nov., are described and illustrated. P. securicornis Fallén is recorded from Japan for the first time. A key to the Japanese species of Phyllomyza is presented.  相似文献

The sensory system of two species of cercariae of the genus Cryptocotyle, C. concavum and C. lingua, is described and differences are indicated in the location of sensillae of both species which make possible the clear differentiation of both species.  相似文献

A new genus, Alloheterophyes, is erected for Heterophyes chini Pearson & Pearson, 1983 and for H. superspinata Leonov & Belogurov, 1965, with which H. bitorquata Pearson & Pearson, 1983 is synonymised. New host and locality records are given. Alloheterophyes differs from Heterophyes in having: (i) a seminal vesicle of two tandem chambers, the distal with a thicker wall; (ii) a uterine seminal receptacle; (iii) an unspined genital atrium; (iv) an inflated, almost triangular excretory bladder; (v) a ventral sucker not close to the gut fork; (vi) the final loop of the uterus dextral to the gonotyl; and (vii) a clavate shape.  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

The life cycle of Metagonimus miyatai Saito, Chai, Kim, Lee and Rim, 1997 (Digenea: Heterophyidae) was studied in the Hiroi River at Kotobuki, Iiyama City, Nagano Prefecture, central Japan. Daughter rediae and cercariae were found in Semisulcospira libertina (Gould) and S. dolorosa (Gould) (Gastropoda: Pleuroceridae). Metacercariae were found encysted in Phoxinus lagowskii steindachneri Sauvage (Osteichthyes: Cyprinidae). Cercariae were experimentally exposed to P. lagowskii steindachneri, and metacercariae were obtained from the fish. Metacercariae of natural and experimental infections were experimentally fed to respective golden hamsters, and gravid adults identifiable as M. miyatai were recovered from the small intestine of the golden hamsters. The daughter redia, cercaria, metacercariae and adults are described. The life cycle of M. miyatai is discussed.  相似文献

A revision of the species of the Proischioscia‐Ischioscia‐group revealed the necessity to synony‐mize the genus Proischioscia Vandel, 1968 with Ischioscia Verhoeff, 1928. The following previously described species are accepted and included in the genus Ischioscia: Ischioscia lobifera Verhoeff, 1928,Ischioscia amazónica Lemos de Castro, 1955, Proischioscia andina Vandel, 1968, Ischioscia bolivari Vandel, 1968, and Proischioscia sturmi Vandel, 1972. Four new species are described: I. stenocarpa, I. hanagarthi and I. longicauda from Peru, and I. irmleri from Brazil. An analysis of the generic and specific characters is given from a viewpoint of phylogenetic systematics.  相似文献

A new genus, a new subgenus, four new species and four previously described species are recorded from the Red Sea. The new genus Anomalorbis has four and a half thoracic segments. Re-discovery of the sinistral variety of Janua (Dexiospira) steueri confirms Sterzinger's observation that this species may coil in either direction. Janua (Fauveldora) anticorrugata sp. nov. is also sinistral and a shallow water species. It therefore appears that the Red Sea may have been the centre of origin for sinistral mutants of the Janua complex. Other of the new forms live in fairly deep water. The assemblage encountered shows closest affinity with the Indo-Pacific, but suggests a high degree of endemism, which may be related to the high temperatures prevailing at all depths in the Red Sea.  相似文献

The Chinese species of the genus Omalus Panzer, 1801 are revised and keyed for the first time. Eight species are recorded, of which four are new to science and one is new to China: Omalus aeneus (Fabricius, 1787), Omalus berezovskii (Semenov-Tian-Shanskij, 1932), Omalus potanini (Semenov-Tian-Shanskij, 1932), Omalus imbecillus (Mocsáry, 1889) (new to China), Omalus helanshanus sp. n., Omalus probiaccinctus sp. n., Omalus pseudoimbecillus sp. n., and Omalus tibetanus sp. n.  相似文献

In order to analyze chromosome numbers and karyotypes of intestinal trematodes belonging to the genus, Metagonimus, the gonad tissues of M. takahashii, M. miyatai, and M. yokogawai were prepared and examined. The number of bivalents in the first meiotic division of M. takahashii was nine (n = 9). The diploid number of M. miyatai was observed to be eighteen (2n = 18) and their chromosomes consisted of one pair of metacentric, 7 pairs of submetacentric, and one pair of telocentric chromosomes. The diploid number of M. yokogawai was thirty-two (2n = 32) and the chromosome complements were composed of two pairs of metacentric, 11 pairs of submetacentric, and three pairs of subtelocentric chromosomes. These results could be a supporting evidence for the validity of the new species, M. miyatai, distinct from M. yokogawai.  相似文献

A new Tubariomyces species from Italy, T. similis, is described and illustrated. It is phenotypically very close to T. hygrophoroides but, based on a combined ITS-LSU rDNA analysis, phylogenetically distinct.  相似文献

The heteronemertean genus Lineus Sowerby, 1806 has been badly in need of revision because of its apparent non-monophyly. In this paper, we focus on Lineus torquatus Coe, 1901, one of the heteronemertean species that occur commonly in waters around the North Pacific, as well as a few other allied species distributed in the western North Pacific, including Lineus alborostratus Takakura, 1898 and Cerebratulus montgomeryi Coe, 1901. Based on phylogenetic analyses using 16S, COI, 28S, 18S, and H3 gene and ITS sequences, we detected a well-supported clade comprised of heteronemerteans with a frontal white band on the head, to which we add Kulikovia gen. nov. This genus is nested within a more comprehensive, highly supported clade, here named the Siphonenteron-clade, which contains Tenuilineus bicolour (Verrill, 1892), Lineus flavescens Coe, 1905, Siphonenteron bilineatum (Renier, 1804), S. cf. bilineatum, Lineus cf. caputornatus, and Lineus sp. from Guam. Our analyses confirmed the presence of a cryptic species of what was formerly known as the cherry-red and reddish forms of Lineus torquatus, herein described as Kulikovia manchenkoi sp. nov. based on some external characters, internal morphology, and the four genetic markers (COI, 16S, H3, and ITS). In contrast to the species pair K. torquataK. manchenkoi, the reddish form of K. alborostrata does not differ genetically from the typical form of this species. The significance of the external and internal characters for distinguishing cryptic species is discussed.

The lectotype of Amebachia baibarana Uchida, 1928, which is the type species of Amebachia Uchida, was re‐examined. Though this species was synonymized with Netelia (Netelia) laevis (= Paniscus laevis Cameron, 1905) and Amebachia has been synonymized under the subgenus Netelia of the genus Netelia, it is concluded that A. baibarana is a distinct species from N. laevis and Amebachia should be a subgenus of the genus Netelia. Netelia laevis is transferred from the subgenus Netelia to Apatagium. Four new species of Netelia (Amebachia), N. (A.) yoshimatsui sp. nov., N. (A.) rasilella sp. nov., N. (A.) fulvistigma sp. nov., and N. (A.) vicinalis sp. nov. are described from Japan, and a key to the species of this subgenus is provided.  相似文献
