Description of the immature stages of Leptonema tridens (Insecta: Trichoptera: Hydropsychidae) from southeastern Brazil with notes on its biology

Abstract: The larva and pupa of Leptonema tridens Mosely, 1933 are described and illustrated. Larvae of L. tridens can be distinguished from other described larvae of Leptonema Guérin, 1843 mainly by the rodlike setae of the labrum and the forecoxa lacking processes, bearing only a row of spiniform setae on its inner surface. The specimens were collected in different localities of the Mantiqueira mountain range, Itatiaia massif, states of Minas Gerais and Rio de Janeiro, southeastern Brazil. Larvae build typical hydrops… Show more

“…Larvae live in a wide range of running water habitats, from small first order streams to large meandering rivers ( Flint and Wallace 1980 , Scott 1983 , Wiggins 1996 , Nessimian and Dumas 2010 ). Oliveira and Froehlich (1996) recorded diatoms as the most frequent food item of an unidentified Brazilian species, but green algae and insect fragments were also common in the gut.…”

“… Oliveira and Froehlich (1996) recorded diatoms as the most frequent food item of an unidentified Brazilian species, but green algae and insect fragments were also common in the gut. The food consumed by larvae of Leptonema tridens was reported to be plant fibers, insect parts, filamentous algae, fungal hyphae, and detrital matter ( Nessimian and Dumas 2010 ), indicating that the species was an omnivorous filterer, likely typical of the genus as a whole.…”

Estos se clasificaron en una de las siguientes categorías: distribución norteamericana, distribución centroamericana, distribución suramericana o cosmopolita.…”

“…Hydropsychidae es una familia abundante y de una amplia distribución geográfica dentro del orden Trichoptera, la cual tiene cerca de 1 500 especies descritas a nivel mundial (Valladolid, Martínez, & Arauzo, 2007;Nessimian & Dumas, 2010). Pueden ser reconocidas por la presencia de branquias abdominales ramificadas y un cuerpo recubierto de setas (Springer, Serrano, & Zepeda, 2010).…”

“…Los trabajos que han evaluado aspectos morfológicos relacionados con las piezas bucales de Leptonema y Smicridea concluyen que es importante incluir dichos análisis para generar claves taxonómicas; o bien, incorporar algunos temas de la biología de los organismos (Nessimian & Dumas, 2010). Dentro de los trabajos que abordan estos géneros se destacan los desarrollados por Muñoz (1999) quien enfatizó en la descripción e ilustración de una nueva especie del genero Leptonema en Costa Rica, elaborando una clave taxonómica para la identificación de los machos de dicha especies.…”
