ABSTRACT

The Neotropical subgenus Notalina (Neonotalina) Holzenthal, 1986 has ten described species in two species groups: brasiliana, formed by seven species from Southeastern Brazilian and Goiás State; and roraima, represented by three species from the Amazonian and Andes regions. In this paper, a new species of Notalina is described and illustrated from specimens collected in the Mantiqueira mountain range, Southeastern Brazil. The new species belongs to the brasiliana group and is easily recognized by the poorly developed dorsomesal and ventrolateral processes and the pair of mound-like protuberances located mesolaterally on abdominal segment X, and by the robust, rounded mesoventral processes and long digitate mesodorsal processes of the inferior appendages. A key to the Neotropical species in the genus is provided.

Keywords: Atlantic Forest, Neotropical, Hudsonemini, new species, identification key.


RESUMO

O subgênero Neotropical Notalina (Neonotalina) possui dez espécies descritas em dois grupos: brasiliana, formada por sete espécies provenientes do Sudeste brasileiro e do Estado de Goiás; e roraima, representado por três espécies das região Amazônica e Andes. Neste trabalho, uma nova espécie de Notalina é descrita e ilustrada a partir de espécimes coletados na Serra da Mantiqueira, Sudeste do Brasil. A nova espécie pertence ao grupo brasiliana e é facilmente reconhecida por processos dorsomesal e ventrolateral pobremente desenvolvidos e por um par de pequenas protuberâncias localizadas mesolateralmente no segmento X, apêndices inferiores com processo mesoventral arredondado e robusto, e processo mesodorsal longo e digitado. Uma chave de identificação para as espécies neotropicais do gênero é fornecida.

Palavras-chave: Mata Atlântica, Região Neotropical, Hudsonemini, espécie nova, chave de identificação.


 

 

Introduction

Leptoceridae (or long-horned caddisflies) are among the three largest families of Trichoptera, with about 1,800 described species and 46 extant genera (Malm & Johanson 2011). The family is currently divided into four subfamilies: Leptocerinae Leach, 1815, with cosmopolitan distribution, Triplectidinae Ulmer, 1906 and Grumichellinae Malm & Johanson, 2011, both with primarily Southern Hemisphere distribution in the Neotropics and Australasia, and Leptorussinae Malm & Johanson, 2011, with only the monotypic genus Leptorussa Mosely, 1953 from Australia (Holzenthal 1986, Morse & Holzenthal 1987, Malm & Johanson 2011).

The genus Notalina Mosely, 1936, which belongs to the subfamily Triplectidinae, tribe Hudsonemini, contains 25 species distributed in two subgenera: N. (Notalina) Mosely, 1936, with 15 species endemic to Australia and Tasmania, and N. (Neonotalina) Holzenthal, 1986, with 10 species exclusively South American in distribution (Calor 2008). The genus is especially diverse in Brazil, where there are seven species described: N. brasiliana Holzenthal 1986, N. cipo Holzenthal 1986, N. froehlichi Calor & Holzenthal 2006, N. goaianensis Calor, 2008, N. hamiltoni Holzenthal 1986, N. morsei Holzenthal 1986, and N. paulista Calor & Holzenthal 2006 (Holzenthal 1986, Calor et al. 2006, Calor 2008).

Holzenthal (1986) recognized two species groups of Neotropical (roraima and brasiliana groups). The roraima species group occurs in the upper Amazon basin, the Northern Andes, and the Guiana Highlands, while species of the brasiliana species group are found in the highlands of Southeastern and Central Brazil (Calor 2008). Herein, a new species of Notalina (Neonotalina) from the Mantiqueira mountain range, Southeastern Brazil is described and illustrated.

 

Materials and Methods

The specimens were collected with Pennsylvania light traps (Frost 1957), Malaise traps, and hand net at Parque Estadual de Campos do Jordão (São Paulo State) and the upper portion of the Itatiaia massif, Itamonte municipality (Minas Gerais State), both located in the Mantiqueira mountain range, an Atlantic Forest highland area of Southeastern Brazil.

The material examined was preserved in 80% alcohol. To observe genital structures, the abdomen was removed and cleared in 10% KOH solution. Both stereo- and optical microscopes were used to examine specimens and specimens were illustrated with the aid of a camera lucida. Morphological terminology follows that of Holzenthal (1986). The type specimens are deposited in Museu de Zoologia, Universidade de São Paulo, Brazil (MZSP), and the Coleção Entomológica Prof. José Alfredo Pinheiro Dutra, Departamento de Zoologia, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil (DZRJ).

 

Taxonomy

Notalina jordanensis, new species

Notalina jordanensis belongs to the brasiliana species group as defined by Holzenthal (1986), by sharing the phallobase with paired, lateral, acuminate flanges and the large, well developed phallotremal sclerite. The new species is most similar to N. brasiliana and N. goianensis, due to the general structure of saddle-like segment X. However, N. jordanensis has the dorsomesal and ventrolateral processes poorly developed on abdominal segment X and has a mound-like protuberance mesolaterally, absent in the other species. Furthermore, the robust and rounded mesoventral processes and the long digitate mesodorsal processes of the inferior appendages, are also useful diagnostic characters for the new species.

Adult: Color (in alcohol) brown to dark brown; legs, palps, and antennae brown. Tibial spur formula 2,2,4. Wing venation as in Figure 1; forewing with forks I, and V presents, with small clear area dorsoapically at thyridial cell; hindwing with forks I, III, and V presents. Forewing length 9.2-10.4 mm (n = 8).

 

 

Male genitalia: Abdominal segment IX annular, broadest ventrolaterally, with pair of small dorsal expansions and setae on lateral edge (Figures 2, 3). Segment X saddle-shaped, with setose, mound-like protuberance mesolaterally, and bearing pair of small ventrolateral processes apically and pair of poorly developed dorsomesal processes (viewed only in dorsal view) (Figures 2, 3). Preanal appendages elongate, smaller than segment X, setose, digitate, rounded at apex (Figures 2, 3). Inferior appendages broad at base, with apical portion elongate, digitate, setose; basodorsal process short, flat, rounded apically; mesodorsal process digitate, slender, with approximately half-length of apical portion, rounded at apex, dorso-medially directed; basoventral protuberance setose, small as viewed laterally, enlarged in ventral view; mesoventral process enlarged, rounded in lateral view, elongate, digitate, rounded at apex, as viewed ventrally (Figures 2, 4). Phallic apparatus with phallic apodeme and phallobase well developed; phallobase with pair of dorsally directed, acuminate flanges, not laterally directed; phallotremal sclerite moderately developed, roughly U-shaped as viewed dorsally (Figures 5, 6).
