Introduction

A new coccidian species of the genus Eimeria Schneider, 1875 (Apicomplexa: Eimeriidae), is reported from the bat host Myotis riparius Handley from Ilha Grande, a large island off the coast of the State of Rio de Janeiro, in southeastern Brazil.

Methods

Bats were captured in 13 mist nets (10 × 3 m), which were set within the experimental plots, and through active searches of the daytime roosts of Molossus molossus Pallas found in Vila Dois Rios. Containment was made in bags for the collection of feces and identification of coccidia. A survey was conducted on the coccidia species described so far (Table 2).

Results

The oöcysts of Eimeria riparii n. sp. are ellipsoidal to cylindroidal with an extremely thin, bi-layered wall, slightly rough. Two polar granules are present, micropyle and oöcyst residuum are both absent. The sporocysts are ellipsoidal, the sporocyst residuum is formed by sparse, rounded granules of varying sizes; the Stieda body is trapezoidal and a sub-Stieda body is absent. Sporozoites are banana shaped. With the new species described here, a total of 40 Eimeria spp. have been described infecting bat hosts, belonging to 30 species of 18 genera and 5 families.

Conclusion

The subsequent increase in the known diversity of bats has been derived from the ongoing expansion of research in a number of different areas of taxonomy and ecology although the number of studies of the associated coccidian parasites of the family Eimeriidae has increased more slowly.

来自巴西大西洋森林的Myotis riparius Handley于1875年（Apicomplexa：Eimeriidae）的新种Eimeria Schneider（Chiroptera：Vespertilionidae），在巴西的大西洋森林中有Eimeria spp的清单。从蝙蝠报道。

介绍

蝙蝠宿主Myotis riparius Handley报道了来自巴西东南部里约热内卢州沿海一个大岛的蝙蝠宿主Myotis riparius Handley ，1875年发现了一种新的球虫，Eimeria Schneider属（Apicomplexa：Eimeriidae）。

方法

蝙蝠被捕获在实验区内的13个薄雾网（10×3 m）中，并通过主动搜索在Vila Dois Rios上发现的Molossus molossus Pallas的白天栖息地捕获了蝙蝠。装在袋子中以收集粪便和鉴定球菌。迄今已对上述球菌物种进行了调查（表2）。

结果

的卵囊艾美耳球虫riparii ñ。sp 。椭圆形至圆柱状，壁极薄，双层，略粗糙。存在两个极性颗粒，都没有微粒和残留的卵囊。孢子囊是椭圆形的，孢子囊残体是由大小不一的稀疏圆形颗粒形成的。施蒂达（Stieda）体是梯形的，而次施蒂达（stieda）体不存在。子孢子是香蕉形的。此处描述了新物种，总共有40个艾美球虫属。已经描述了蝙蝠宿主的感染，它们属于18属5科的30种。

结论

蝙蝠的已知多样性的随后增加是由于对分类学和生态学的许多不同领域的研究不断扩展而引起的，尽管对家蝇科的相关球虫寄生虫的研究数量增长得较为缓慢。
