摘要
在秘鲁马德雷德迪奥斯（Madre de Dios）附近的亚马逊河流域采集到的两种淡水鱼的鳃丝中发现了两种新的双触角蠕虫，即来自Loricaria sp.（丝状目：Loricariidae）的Demidospermus wilveri n. sp.和来自Brycon amazonicus (Spix & Agassiz) （丝状目：Bryconidae）的Notozothecium agusti n. sp.。Demidospermus wilveri n. sp.的特征是具有以下组合特征：（1）雄性交配器官（MCO）具有 1.5 个环和勺状的远端；（2）附属片具有膨大的远端；（3）背板和腹板条具有宽 V 形和膨大的末端；（4）钩的大小相似。Notozothecium agusti n. sp. 与其 10 个同系物的不同之处在于以下特征组合：(1) 带有 1½ 环的卷曲 MCO 和远端呈肾形的蜿蜒附属片，(2) 背条呈杆状且笔直，(3) 锚具具有粗壮的表层根。Demidospermus wilveri n. sp.是该属的第 32 个物种，是秘鲁的第 8 个物种，也是寄生于秘鲁亚马逊河鲶鱼的第 5 个物种。Notozothecium agusti n. sp.是在秘鲁描述的该属的第二个物种，也是第一个感染双子叶鲶宿主的物种。
Two new species of dactylogyrids (Monogenea: Dactylogyridae) infecting the gill filaments of fishes in the southern Peruvian Amazon.
Two new dactylogyrid species were found infecting the gill filaments of two freshwater fishes collected in the Amazon River basin around Madre de Dios, Peru, namely, Demidospermus wilveri n. sp. from Loricaria sp. (Siluriformes: Loricariidae), and Notozothecium agusti n. sp. from Brycon amazonicus (Spix & Agassiz) (Characiformes: Bryconidae). Demidospermus wilveri n. sp. is characterized by having the following combination of characteristics: (1) a male copulatory organ (MCO) with 1½ rings and a spoon-shaped distal end, (2) an accessory piece with expanded distal end, (3) dorsal and ventral bars with broadly V-shaped and expanded ends, and (4) hooks similar in size. Notozothecium agusti n. sp. differs from its ten congeners by the following combination of characteristics: (1) a coiled MCO with 1½ rings and a sinuous accessory piece with kidney-shaped distal end, (2) an rod-shaped and straight dorsal bar, (3) and anchors with robust superficial roots. Demidospermus wilveri n. sp. represents the thirty-second species in the genus, the eighth from Peru and the fifth parasitising a loricariid catfish from the Peruvian Amazon. Notozothecium agusti n. sp. is the second species of the genus described in Peru and the first species infecting a bryconid host.
期刊介绍：
Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
