Abstract

A new kathlaniid nematode, Falcaustra peruensis n. sp., was described using light and scanning electron microscopy, based on specimens collected from the intestine of the Titicaca water frog, Telmatobius culeus (Garman) (Anura: Telmatobiidae) in Peru. Falcaustra peruensis n. sp. belongs to the Falcaustra group that is characterized by the presence of a pseudosucker. The new species can be easily differentiated from other congeneric species, with the exception of four species, by its papillae pattern. This pattern includes 6 precloacal papillae, 4 adcloacal papillae, 12 postcloacal papillae, plus 1 median papilla. The new species shares similarities with Falcaustra peruensis n. sp. by having the same papillae pattern (6-4-12 + 1) and a pseudosucker, but can be differentiated from F. sanjuanensis by the morphology of the gubernaculum (triangular with a pair of proximal and distal processes in the new species vs triangular without processes in F. sanjuanensis), the proportion of gubernaculum length relative to total body length (1.2-1.24% in the new species vs 1.56-1.71% in F. sanjuanensis), the morphology of the deirids (button-shaped surrounded by a horseshoe-shaped border in the new species vs elongated surrounded by a circular border in F. sanjuanensis) and body size (males 6.14-7.62 mm and females 4.1-6.8 mm in the new species vs males 11.2-13.5 mm and females 10.1-15.5 mm in F. sanjuanensis). Falcaustra peruensis n. sp. represents the fourth nominal species of the genus in Peru and the fourteenth species described in the Neotropical region.

秘鲁的的的喀卡水蛙(无尾目:水蛙科)一新种,1915(线虫纲:水蛙科)。
利用光镜和扫描电镜对秘鲁的的的喀喀湖水蛙(Telmatobius culleus (Garman))(无尾目:端蛙科)的肠道标本进行了描述,发现了一种新的kathlaniid线虫Falcaustra peruensis n. sp.)。秘鲁Falcaustra perensis n. sp.属于以假吸盘存在为特征的Falcaustra组。新种可以很容易地从其他同属种中区分出来,除了四个种外,它的乳头形态。该型包括6个腔前乳头,4个腔内乳头,12个腔后乳头,外加1个正中乳头。新种与秘鲁falcaaustra perensis n. sp.具有相同的乳头形态(6-4-12 + 1)和假吸体,但可以通过管骨形态(新种为三角形,具有一对近端和远端突起,而三juanensis为三角形,没有突起)、管骨长度相对于体长的比例(新种为1.2-1.24%,而三juanensis为1.56-1.71%)与三juanensis区分。子代的形态(新种为钮扣状,周围有马蹄形边界;新种为长形,周围有圆形边界)和体型(新种为雄6.14 ~ 7.62 mm,雌4.1 ~ 6.8 mm;新种为雄11.2 ~ 13.5 mm,雌10.1 ~ 15.5 mm)。秘鲁Falcaustra peruensis n. sp.代表秘鲁该属的第四个命名种和新热带地区所描述的第十四个种。

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.
