A new species of Nectopsyche Müller, 1879 (Trichoptera: Leptoceridae) and notes on the adults of Nectopsyche splendida ()

ABSTRACT

ABSTRACT The male and female of a new species in the long-horned caddisfly genus Nectopsyche Müller, 1879 are described from southeastern Brazil. The new species has male genitalia similar to species of the candida-group, but has several endothecal spines in the phallic apparatus similar to those of gemma-group species. The color pattern of the scales and hairs on the head, thorax and forewings is similar to that of Nectopsyche splendida (Navás, 1917), as both species have bands of metallic silver-iridescent scales interleaved with black areas on the forewings. Additionally, we present illustrations of the male and female genitalia of N. splendida and expand the knowledge of its distribution.
