Abstract

The Serra dos rgos National Park (PARNASO) is a federal conservation unit located in Rio de Janeiro State, within the Atlantic Forest biome. This biome is one of the worlds biodiversity hotspots and has high diversity and endemism of caddisfly taxa. Here, we present a checklist of caddisflies from PARNASO, including the description of two new species of Ochrotrichia Mosely (Hydroptilidae). Ochrotrichia sino sp. nov. and Ochrotrichia papel sp. nov. are assigned to the O. aldama Species Group due to the divided tergum X in male genitalia, although in the first one tergum X is not simple as in most species in this group. Ochrotrichia sino sp. nov. is recognized by tergum X having a broad basal portion bearing a basodorsal spine-like process on the left side and the apical portion with two elongate processes, one curved and crossing the other one underneath. Ochrotrichia papel sp. nov. is distinguished by the elongate inferior appendages, by tergum IX having its posterior margin obliquely emarginate, and tergum X being divided into two processes, the left one longer and almost straight, the right one curved to the left, slightly upturned in lateral view. The list of PARNASO species is based on isolated records in literature and on specimens in the Coleo Entomolgica Professor Jos Alfredo Pinheiro Dutra, Universidade Federal do Rio de Janeiro (Departamento de Zoologia) [UFRJ (DZRJ)], with samples collected since 2009. A total of 95 species were recorded from the PARNASO, of which eight are new distributional records for Rio de Janeiro State. Hydroptilidae (27 spp.), followed by Hydropsychidae (13 spp.), Leptoceridae, and Philopotamidae (12 spp. each) are the families with highest species richness. Before this work, only about 20 species of caddisflies were formally registered from the park area. In this way, this work is an important contribution to fill the gaps of knowledge caused by Wallacean and Linnean shortfalls.

摘要

塞尔拉多斯奥戈斯国家公园（PARNASO）是一个位于巴西里约热内卢州的联邦保护区，位于大西洋森林生物群系内。这个生物群系是世界生物多样性热点地区之一，拥有丰富的蜉蝣类物种多样性和特有性。在这里，我们提供了一份来自 PARNASO 的蜉蝣类清单，包括描述了两种新的 Ochrotrichia Mosely（Hydroptilidae 科）物种。 Ochrotrichia sino sp. nov. 和 Ochrotrichia papel sp. nov. 由于雄性生殖器的第十背板 X 是分开的，被归入 Ochrotrichia aldama 物种群，但在第一个物种中，第十背板 X 并不像该群大多数物种那样简单。 Ochrotrichia sino sp. nov. 的第十背板 X 具有宽阔的基部，左侧有一个背侧刺状突起，顶部有两个长突起，一个弯曲，另一个在下面交叉。 Ochrotrichia papel sp. nov. 的区别在于其延长的下附肢、第九背板后缘斜截形和第十背板 X 分为两个突起，左侧较长且几乎笔直，右侧向左弯曲，在侧面观时略微向上翘起。 PARNASO 物种清单基于文献中的孤立记录和在里约热内卢联邦大学（动物学系）Coleo Entomolgica Professor Jos Alfredo Pinheiro Dutra [UFRJ (DZRJ)] 的标本，这些标本是自 2009 年以来收集的。从 PARNASO 共记录了 95 种物种，其中 8 种是里约热内卢州的新分布记录。 Hydroptilidae（27 种）、Hydropsychidae（13 种）、Leptoceridae 和 Philopotamidae（各 12 种）是物种丰富度最高的科。在此之前，只有大约 20 种蜉蝣类正式登记在公园范围内。因此，这项工作是对填补华莱士和林奈短缺陷阱造成的知识空白的重要贡献。
