Acanthogyrus (Acanthosentis) bilaspurensis Chowhan, Gupta & Khera, 1987 is a poorly known acanthocephalan species reported from the reba carp Cirrhinus reba (Hamilton) (Cypriniformes: Cyprinidae) in India. In the present study, the detailed morphology of A. (Acanthosentis) bilaspurensis were studied using light microscopy and, for the first time, scanning electron microscopy (SEM), based on newly collected specimens from the common carp Cyprinus carpio Linnaeus (Cypriniformes: Cyprinidae) in Pakistan. The SEM observations revealed the outer shell of eggs with numerous remarkable protuberances and the gonopore of female located at a discoid protrusion surrounded by some very small spines. This is the first time that A. (Acanthosentis) bilaspurensis was reported in Pakistan, and the common carp represents a new host for this species. In addition, the molecular characterization of the 18S and 28S rDNA of A. (Acanthosentis) bilaspurensis is provided for the first time. There was no intraspecific genetic variation detected in the 18S and 28S regions between different individuals of A. (Acanthosentis) bilaspurensis, but high level of interspecific nucleotide divergence was found in the 18S (4.15–16.7%) and 28S regions (3.60–15.4%). Phylogenetic results based on the 18S, 28S and 18S + 28S sequence data, respectively, all revealed the Quadrigyridae, Pallisentinae and the genus Neoechinorhynchus are not monophyletic groups, and the genera Acanthogyrus and Pallisentis have far relationship. The systematic status of the genus Acanthogyrus and some species of Neoechinorhynchus need further clarify based on different mtDNA and nuclear DNA data including broader representatives of the class Eoacanthocephala.  相似文献

Abstract. The fruit fly genus Ceratitis (Diptera: Tephritidae) comprises several important pest species attacking a wide range of unrelated fruits. In this paper the subgenus Ceratitis ( Pardalaspis ) Bezzi is revised. Ten species are recognized of which five are described as new: C.(P.)hamata sp.n., C.(P.)munroi sp.n., C.(P.)serrata sp.n., C.(P.)semipunctata sp.n. and C.(P.)zairensis sp.n. A key to both sexes is provided. All species are restricted to the Afrotropical Region and distributional and known host plant data are given.  相似文献

Tetrameres (Tetrameres) tinamicola sp. n. is described from the crested tinamou, Eudromia elegans, of Argentina. The new species is most similar to other alate species of the subgenus Tetrameres, but it can be differentiated on the basis of its large size, length and structure of the left spicule, and arrangement of the 5 subventral and 3 sublateral pairs of postanal papillae. A review of the subgenus Petrowimeres is presented including the reassignment of several species to the subgenus Tetrameres.  相似文献

The subgenus Epicterodes Wehrli, 1933 of Arichanna Moore, 1868 is reviewed. Six species are recognized, of which, A. (E). denticularia sp. nov. is described as new to science from China. One new synonym is established based on morphological and genetic similarity: A. (E.) flavomacularia Leech, 1897 (=A. (E.) perimelaina Wehrli, 1933 syn. nov.). Results of DNA barcoding for Epicterodes are briefly discussed. Diagnoses for all the species are provided and illustrations of adults, genitalia and distribution map are presented.  相似文献

The morphological characters used to differentiate species in the genus Labiostrongylus Yorke & Maplestone, 1926, parasitic in macropodid and potoroid marsupials, are discussed. The genus is divided into three subgenera Labiostrongylus (Labiostrongylus), L. (Labiomultiplex) n. subg. and L. (Labiosimplex) n. subg. on the basis of the presence or absence of interlabia and the morphology of the oesophagus. A key to the subgenera is given and a detailed revision of two of the subgenera is presented. Keys to each of the subgenera are given, the species discussed being: L. (L.) labiostrongylus) (type-species) (syn. L. (L.) insularis, L. (L.) grandis, L. (L.) macropodis sp. inq. and L. (L.) nabarlekensis n. sp., in the subgenus Labiostrongylus, and L. (Lm.) eugenii, L. (Lm.) novaeguineae, L. (Lm.) onychogale, L. (Lm.) uncinatus, L. (Lm.) billardierii n. sp., L. (Lm.) constrictis n. sp., L. (Lm.) kimberleyensis n. sp., L. (Lm.) thylogale n. sp., and L. (Lm.) potoroi, n. sp., in the subgenus Labiomultiplex.  相似文献

Strobilomyces echinocephalus Gelardi & Vizzini sp. nov. is described as a new species, based on collections from Kunming (Yunnan Province, China). Macro-morphological and micro-morphological features, ecological data and analyses of RPB1 and ITS2 sequences support the establishment of this new taxon. Colour pictures of fresh basidiomata in habitat, scanning electron microscope (SEM) micro-photographs of the spores, and a line-drawing displaying the most relevant anatomical characters are provided in this paper. Strobilomyces zangii Gelardi nom. nov. is proposed to replace the name Heimiella nigricans M. Zang. A dichotomous key to the Strobilomyces species at global level is also provided at the end of this work.  相似文献

Cinclotaenia sp., described originally by Georgiev & Genov (1985) from the dipper Cinclus cinclus (L.) in Bulgaria, has recently been identified from the same host in the Carpathian Mountains in the Slovak Republic. This tapeworm is considered to be a new species, which is named C. georgievi n. sp. It is characterised by: a scolex armed with 23-27 (predominantly 24-26) hooks in two rows; hooks 30.5-36 microm long, with a blade 10-13.5 microm long and resembling in shape the diorchoid hooks of hymenolepidids; irregularly alternating genital pores with simple genital atria; a slightly conical cirrus armed by small spines of up to 3 microm in length; 24-51 testes posterior to a bi-alate, branched ovary; a gravid uterus filled with egg packets; and eggs with filaments. C. georgievi n. sp. differs from the closely-related C. tarnogradskii (Dinnik, 1927) in the slightly higher number of rostellar hooks, which have longer blades, and a larger cirrus.  相似文献

Three new species of the subgenus Parapenthecia of the genus Apenthecia are reported from the Oriental Region: A. (P.) heterochaeta Chen and Toda, sp. nov. from Indonesia, and A. (P.) hispida Chen and Toda, sp. nov. and A. (P.) litongi Cao and Chen, sp. nov. from south China. Interestingly, the last species lacks a very peculiar character, the swollen or scale‐like orbital setae, which are commonly seen in all other species of the genus Apenthecia. A key to all species of the subgenus Parapenthecia is provided.  相似文献

The authors describe and illustrate two hymenolepidid cestodes parasitising Himantopus melanurus (Aves) from Paraguay. Microsomacanthus kaulobatroni n. sp., 20–30 long × 0.6 mm wide, with 10 diorchoid hooks 33–38 µm long, three testes in a transverse row, short cirrus 20–28 µm long armed with very minute spines, a short vagina with a sphincter, and a multi-lobed ovary, with genital ducts similar to those of Hymenolepis himantopodis ( sensu Fuhrmann, 1906) but with rostellar hooks different from those of Tænia himantopodis Krabbe, 1869 sp. inq. Wardium neotropicale n. sp., 40-50 long x 0.9 mm wide, has campanulate proglottides, scolex with 10 aploparaksoid rostellar hooks 9 µm long, testes arranged in a triangle, a short cirrus pouch without a transverse retractor muscle, very short, unarmed cirrus, a short vagina with a sphincter (30–35 µm in diameter) but no retractor muscle, a multi-lobed ovary and a bipartite uterus. The shape of the hooks distinguishes this species from T. himantopodis Krabbe, 1869 and other aspects of its anatomy from other species of Wardium with hooks of a similar size. A single specimen of a third Hymenolepis (sensu lato) species (lacking the scolex) could not be identified.  相似文献

Phyllodiaptomus christineae n.sp. is described from Thailand. It stands out, in the male, by the shape and the armature of the second exopodite-segment of the right P5 and by the elongate apical process and ornamentation of the second exopodite-segment of the left P5; in the female, by the reduced lateral wings of the fifth pediger, and by the form of the genital somite. Together withP. blanci, P. tunguidus andP. longipes, the new species constitutes the blanci-group, here raised to the level of a subgenus (Phyllodiaptomus s.s.) with representatives in Central Asia, China, Borneo and Thailand. A second subgenus (Ctenodiaptomus subgen. nov.) is created to accommodate the four Asian species of the annae-group.  相似文献
