Contulma vascaina sp. n. (Insecta: Trichoptera: Anomalopsychidae), a new species from Rio de Janeiro state, southeastern Brazil

Leandro Lourenço Dumas

Abstract: The caddisfly genus Contulma Flint, 1969, with 30 described species, is endemic to the Neotropics. In addition to the five species currently recorded from Brazil, a new species of Contulma is described and illustrated in this work. Contulma vascaina sp. n. is similar to C. sana Jardim and Nessimian, 2011 in prominent, slender and rod-like posterolateral lobe of segment IX, but the new species has a shorter posterolateral lobe, with long, spine-like seta apically. Contulma vascaina sp. n. can also be characteri… Show more

The Serra dos Órgãos 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 world’s 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 Coleção Entomológica Professor José 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.

In Brazil, about 900 species of Trichoptera have been recorded, with some species in all Brazilian states. Nevertheless, the collection effort is unequal, with several under-sampled regions. Despite being located entirely within the Atlantic Forest ecoregion, a hotspot of biodiversity, Espírito Santo State has a low known caddisfly richness when compared to nearby areas in the same ecoregion, especially for the infraorder Brevitentoria. This suggests the existence of a Trichoptera biodiversity knowledge gap. Aiming to overcome these taxonomic and distributional shortfalls, we performed a comprehensive inventory of the Brevitentoria species in the state. The sampled sites were distributed from North to South of the state covering 22 locations. In total, 3,420 adult specimens of Brevitentoria were analyzed, leading to a total of 40 species. Two families and 27 species are recorded for the first time from the state. Additionally, we describe three new species of the genera Phylloicus, Helicopsyche (Feropsyche), and Marilia. As a result of this survey, we increase by 100% the number of species of Brevitentoria known from the state, and by 30% for the number of known Trichoptera species. Based on incidence data from this inventory and from the literature, the Brevitentoria species richness was estimated to be about 72 species in Espírito Santo State.

Herein we add eight new country records to Panama’s caddisfly fauna (Insecta, Trichoptera): Hydropsychidae – Leptonema turrialbum Flint, McAlpine & Ross, 1987; Polycentropodidae – Polyplectropus bravoae Bueno-Soria, 1990; Hydroptilidae – Mayatrichia ayama Mosely, 1937 and Bredinia selva Harris, Holzenthal & Flint, 2002; Glossosomatidae – Mortoniella stilula Blahnik & Holzenthal, 2008; Anomalopsychidae – Contulma talamanca Holzenthal & Flint, 1995; Helicopsychidae – Helicospyche planata Ross, 1956; and Odontoceridae – Marilia crea Mosely, 1949. The Republic of Panama now has 533 species of caddisflies distributed among 15 families and 56 genera.
