The endemic Neotropical long-horned caddisfly subgenus Notalina (Neonotalina) Holzenthal contains nine described species in two species groups, the brasiliana and roraima groups, from the Brazilian Southeastern and Amazonian regions, respectively. In this paper, a new species of Notalina in the brasiliana species group, from Chapada dos Veadeiros National Park, Goiás state, Brazil, is described and illustrated. The new species is easily recognized by the following character set: presence of two pairs of processes on abdominal segment X; presence of well-developed basoventral protuberances, mesally directed in ventral view; presence of triangle-shaped, acuminated mesoventral process on the inferior appendages; and phallic apparatus with flanges slightly curved in dorsal view, not laterally directed.

Keywords: caddisflies, description, Hudsonemini, Neotropical, taxonomy.


O subgênero neotropical Notalina (Neonotalina) Holzenthal contém nove espécies descritas em dois grupos de espécies, brasiliana e roraima, provenientes do Sudeste brasileiro e da região Amazônica, respectivamente. Neste artigo, uma nova espécie de Notalina é descrita e ilustrada a partir de espécimes colecionados no Parque Nacional da Chapada dos Veadeiros, Goiás, Brasil. A nova espécie é facilmente diagnosticada pelo seguinte conjunto de caracteres: presença de dois pares de processos no segmento abdominal X; presença de protuberâncias basoventrais bem desenvolvidas, mesalmente direcionadas em vista ventral; presença de processo mesoventral acuminado, com formato triangular no apêndice inferior, e aparato fálico com extensões laterais levemente curvadas em vista dorsal, não direcionadas lateralmente.

Palavras-chave: descrição, Hudsonemini, Neotropical, taxonomia, tricópteros.




Leptoceridae Leach 1815 is a cosmopolitan family of caddisflies containing 1,567 described species, making it the second largest family in the order Trichoptera after the Hydroptilidae (1,677 species) in known species richness (Morse 2003). In the Neotropics, there are 13 described leptocerid genera in two subfamilies, seven genera in the Leptocerinae Ulmer (Achoropsyche Holzenthal, Amphoropsyche Holzenthal, Brachysetodes Schmid, Nectopsyche Müller, Neoathripsodes Holzenthal, Oecetis McLachlan, and Triaenodes McLachlan) and six genera in the in Triplectidinae Kolenati (Amazonatolica Holzenthal & Pes, Atanatolica Mosely, Grumichella Müller, Hudsonema Mosely, Notalina Mosely, and Triplectides Kolenati).

The genus Notalina was erected by Mosely (1936) for three Australian species, Notalina parkeri (type species), N. delicatula (Ulmer) 1908, and N. flava (Ulmer) 1908. Since then, 24 species have been described in two subgenera, N. (Notalina) and N. (Neonotalina) Holzenthal from the Australian and Neotropical regions, respectively. Since the first three species of Notalina (Notalina), 12 additional species have been described: N. arena St. Clair 1991, N. bifaria Neboiss 1977, N. dwellinga Neboiss 1982, N. fulva Kimmins 1953, N. gungara Neboiss 1984, N. moselyi Kimmins 1953, N. nigra (Mosely) 1953, N. ordina St. Clair 1991, N. pseudodelicatula Neboiss 1982, N. salina St. Clair 1991, N. spira St. Clair 1991, and N. tillyardi Kimmins 1953. Of these taxa, immature stages have been described for seven species (N. arena, N. fulva, N. ordina, N. salina, N. spira, N. parkeri, and N. tillyardi) by St. Clair (1991). In the Neotropical subgenus, there are nine described species: N. brasiliana Holzenthal 1986, N. morsei Holzenthal 1986, N. cipo Holzenthal 1986, N. hamiltoni Holzenthal 1986, N. roraima Holzenthal 1986, N. nanay Holzenthal 1986, N. matthiasi Holzenthal 1986, N. paulista Calor & Holzenthal 2006, and N. froehlichi Calor & Holzenthal 2006. Holzenthal (1986) recognized two groups of Neotropical species (roraima and brasiliana groups), and this hypothesis was corroborated by the cladistic analysis of Calor et al. (2006).

Recently, Calor & Froehlich (2008) described the immature stages of Notalina morsei, the first description of the larvae of N. (Neonotalina) subgenus, and provided an updated key to known larvae of Neotropical Leptoceridae genera. In this paper, a new species of Notalina (Neonotalina) Holzenthal 1986 from Chapada dos Veadeiros National Park, Goiás state, Brazil is described and illustrated.


Material and Methods

The specimens were collected at Chapada dos Veadeiros National Park, a reserve located in the Northern Goiás state (13º 51' to 14º 10' S and 47º 25' to 47º 42' W), Brazil. The natural vegetation of this reserve is characterized by a predominance of forest formations at low elevations and Cerrado with rupestrian areas at high elevations. The specimens will be deposited in Museu de Zoologia, Universidade de São Paulo, Brazil (MZSP), as discussed in the "Material examined" section.

Methods used in the collection, preparation, examination, illustration, and description of the species were those discussed by Holzenthal & Andersen (2004) and Blahnik & Holzenthal (2004). The morphological terminology used in this paper follows that described and figured by Schmid (1980) and used by Holzenthal (1986) and Calor et al. (2006).

Notalina goianensis n. sp. (Figures 1-2)

As in other species of the brasiliana species group, the new species of Notalina can be recognized by the presence of lateral, acuminate flanges on the male phallobase and well-developed phallotremal sclerites. The new species can be distinguished by elongate mesodorsal process, acuminate mesoventral processes; well-developed basoventral protuberances, setose and mesally directed in ventral view; and by having the flanges of the phallic apparatus slightly curved in dorsal view.

Male: Color brown to dark brown, with small white wing spots (specimens in alcohol). Tibial spur formula 2,2,4. Wing venation as in Figure 1. Forewing length 7.0-9.5 mm (N = 8), forks I and V present, a lucid area between the veins Sc and R2. Hindwing forks I, III and V present, fork I very narrow. Genitalia as in Figure 2. Abdominal segment IX annular, broadest ventrolaterally, with pair of small dorsal expansions and setae on lateral border. Segment X saddle-like, bearing pair of broadly digitate ventrolateral processes apically and pair of digitate, setose dorsomesal processes. Preanal (or superior) appendage long, about 2/3-length of segment X, setose, slightly clavate. Inferior appendage with apical portion elongate, digitate, setose; basal portion bearing various processes: short, flat, apically rounded basodorsal process; long, slender mesodorsal process, its apex narrowed, dorso-medially directed; well-developed, rounded, setose, basoventral protuberance, its mesal border extended mesad in ventral view; and long, triangular, acuminate mesoventral process. Phallic apparatus with phallic apodeme and phallobase well developed; phallobase with pair of acuminate flanges, its apex dorsally, not laterally, directed; phallotremal sclerite developed mesad, but smaller than that of N. brasiliana, roughly U-shaped in dorsal view, apex acuminate.

Female: Color similar to male (specimens in alcohol). Tibial spur formula 2,2,4. Forewing length 6.0-7.5 mm (N = 4), forks I, III and V present. Hindwing forks I, III and V presents, fork I very narrow. Genitalia and wings venation not distinguishable from those of N. brasiliana, thus not figured here.

Immatures: Unknown.

Material examined: Holotype: male, BRAZIL: Goiás state, Chapada dos Veadeiros National Park, Alto Paraíso, Ribeirão Água Fria, 14º 05' 26.3" S and 47º 29' 38.5" W, 1225 m, 16.xii.2006 (Bispo, Yokoyama & Paciencia) (MZSP). Paratypes: 4 males and 4 females, BRAZIL: Goiás state, Chapada dos Veadeiros National Park, Alto Paraíso, Ribeirão Água Fria, 16.xii.2006 (Bispo, Yokoyama & Paciencia) (MZSP); 3 males, BRAZIL: Goiás state, Chapada dos Veadeiros National Park, Alto Paraíso, Loquinhas, 14º 08' 40.1" S and 47º 29' 18.6" W, 15.xii.2006 (Bispo, Yokoyama & Paciencia) (MZSP).

Etymology: This specific epithet, goianensis, refers to the Brazilian state of Goiás, where Chapada dos Veadeiros National Park is situated, and also the state of origin of the collector of this material, Dr. Pitágoras Bispo.



As discussed in the species description, N. goiansensis is placed in the brasiliana species-group by the presence of lateral, acuminate flanges on the male phallobase and well-developed phallotremal sclerites, both synapomorphies of this clade (Holzenthal 1986, Calor et al. 2006). The new species is most similar to N. brasiliana due to the presence of two pairs of processes on abdominal segment X and by the complex nature of the basal half of the inferior appendage in the male genitalia. Unlike N. brasiliana, the new species has the dorsomesal processes of segment X small, ½ the length of the ventrolateral processes, the basoventral protuberances well-developed, mesally directed in ventral view, the mesoventral process acuminate, triangle-shaped on the inferior appendages, the flanges of phallic apparatus slightly curved in dorsal view, not laterally directed, unlike N. brasiliana. The phallotremal sclerite is small in the first too.
