前睾吸虫亚科的研究（吸虫纲：半尾科）

本文介绍了半尾科前睾亚科吸虫的发现、变迁和研究历史。在半尾科中仅有该亚科的虫种是睾丸均在腹吸盘之前,并依两性管和受精囊的有无等特征分为前睾属和拟前睾属两属。文内还叙述了一个新种,天津前睾吸虫Prosorchis tianjinensis sp. nov. 并讨论了新种与前黄前睾吸虫、西沙前睾吸虫两近似种的区别。本亚科原来虫种均系海产鱼寄生虫,惟我们这个新种发现于淡水鱼黄鳝,扩大了该类吸虫宿主的分布范围。

坚盘属(Pycnoporus)吸虫的分类及三新种的描述(吸虫纲:枝腺科)

关于我国枝腺科(Lecithodendriidae Odhner,1911)吸虫,福井玉夫与尾形藤治(1939)曾报告东北地区所采得的肠前腺属(Prosthodendrium)吸虫一种;陈心陶(1954)对肠前腺属吸虫的分类进行了研究,记载了华南地区采得的肠前腺属吸虫六种,并将肠前腺属中具有长形口吸盘与长形口的虫种分出,另建长吸盘属(Longitrema Chen,1954)。综上所述,我国已有记载的枝腺科吸虫仅肠前腺属六种,本科其他属虫种尚未见文献记载。作者

山羊肝脏中扁体吸虫属的一新种

山羊扁体吸虫Platynosomum capranum sp.nov.寄生在昆明的山羊肝脏内。这一新种吸虫为第四种寄生在哺乳类体内的扁体吸虫,也是扁体吸虫属在我国的初次记录。 虫体形小,体长平均3.538毫米,阔平均1.088毫米。表皮光滑。精巢形大,排列於腹吸盘後半部之後,阴茎囊延长,囊内藏有贮精囊之外,前端还有一个锥形的阴茎,长0.126—0.158毫米,常伸出於生殖孔之外。生殖孔位於肠叉之後。卵巢位於左精巢之後。具受精囊与卵壳腺。卵黄腺的长度约为体长的1/5。 本新种的形体与P.semifuscum Looss,1907相似。由於它寄生於哺乳类山羊的肝脏里,体形较小、精巢边缘平滑无叶,阴茎明显;这些特徵显与P.semifuscumLooss相区别,因此认它为扁体吸虫属中的一个新种。 文中把斯克里亚平氏所确定的11个独立种与本新种一起,作了一个检索表;但是几个未能确定的待考种与在有袋类体内发现的一个未定名的种,并未包括在表内。

New species of Moravecia (Nematoda: Dracunculoidea) from body cavity of marine perciform fish Percophis brasiliensis in Argentina

A new species of dracunculoid nematode, Moravecia argentinensis n. sp. (Guyanemidae), is described from the blood vessels and body cavity of Brazilian flathead, Percophis brasiliensis Quoy et Gaimard (Perciformes: Percophidae), from off the coast of Argentina. The new species differs from the only other congeneric species, Moravecia australiensis Ribu et Lester, 2004, mainly in the number (14) of cephalic papillae, the length ratio of the muscular and glandular portions of esophagus (1:1-2), more numerous (3-5 pairs) genital papillae in the male, and the presence of a sclerotized copulatory plate. This is the second known species of Moravecia Ribu et Lester, 2004 and the first species of this genus reported from South American waters.

Urotrema shirleyae n. sp. (Trematoda: Digenea: Urotrematidae) in Norops oxylophus and N. cupreus (Squamata: Iguania: Polychrotidae) from the Area de Conservación Guanacaste, Costa Rica

A new species of Urotrema inhabits Norops oxylophus and Norops cupreus from the Area de Conservación Guanacaste, Costa Rica. The new species is most similar to Urotrema scabridum but differs by having a relatively longer esophagus, at least 10% of the total body length versus 4-8% in U. scabridum; an oral sucker width: ventral sucker width ratio less than 1 : 1 (averaging 1 : 0.76) versus 1 : 1 or greater; an oral sucker width : pharyngeal width ratio less than 1 : 0.5 (averaging 1 : 0.42) versus greater than 1 :0.5; and by having many transversely oriented posttesticular uterine loops versus a few vertically oriented posttesticular uterine loops.     

Arthropod symbiotes of Laonastes aenigmamus (Rodentia:Diatomyidae)

Arthropod symbiotes of the Laotian rock-rat, Laonastes aenigmamus (Rodentia:Diatomyidae), from Laos are examined. This host is a member of Diatomyidae previously thought to have gone extinct >10 million yr ago. Permanent symbiotes are represented by 2 species, a new species of sucking louse, Polyplax sp., near rhizomydis (Phthiraptera:Polyplacidae), and a new species of fur mite, Afrolistrophorus sp., near maculatus (Acariformes:Listrophoridae). The temporary parasites are represented by 18 species, i.e., 1 mesostigmatan species, i.e., a new species of Androlaelaps near casalis (Parasitiformes:Laelapidae); immature stages of 2 tick species, Ixodes granulatus and Haemaphysalis sp. (Parasitiformes:Ixodidae); and a rich fauna of chiggers (Acariformes:Trombiculidae) comprising 8 genera and 15 species. It is hypothesized that this host completely lost its initial fauna of ectosymbiotes and that ancestors of the recorded symbiotes switched to this host from rodents of the superfamily Muroidea.     

云南省鱼类寄生甲壳动物包括一新种的描述

Morphological and molecular characterisation of Heliconema hainanensis sp. nov. (Spirurina: Physalopteridae) from congers in the South China Sea,with a key to the species of Heliconema

Heliconema hainanensis sp. nov. collected from Uroconger lepturus (Richardson) (Anguilliformes: Congridae), Muraenesox cinereus (Forsskål) and Congresox talabonoides (Bleeker) (Anguilliformes: Muraenesocidae) in the South China Sea was described using light and scanning electron microscopy. The new species differs from its congeners by the following morphology: pseudolabia, the number and arrangement of caudal papillae (4 pairs of pedunculate precloacal papillae arranged in 2 groups of 2 and 2 pairs and 6 pairs of pedunculate postcloacal papillae arranged in 4 groups of 1, 2, 1 and 2 pairs), the length of spicules [left spicule 0.51-0.69 mm, right spicule 0.20-0.27 mm, spicule (right:left) ratio 1:2.20-2.69] and the morphology of the female tail tip. In addition, specimens of the new species collected from the three different hosts and specimens of an unidentified species of Heliconema collected from U. lepturus were characterised using molecular methods by sequencing the internal transcribed spacer (ITS) of ribosomal DNA. Analyses and comparison of the ITS sequence of H. hainanensis sp. nov. with Heliconema sp. support the validity of the new species based on morphological observations. An identification key to the species of Heliconema is also provided.
