Complementary studies of the Perlidae (Insecta: Plecoptera) fauna from the Paranapiacaba Mountains using DNA barcode...

Area of Science:

• Entomology
• Zoology
• Molecular Biology

Background:

• The Paranapiacaba Mountains in Brazil have a well-documented stonefly fauna, but knowledge gaps persist.
• Accurate identification of immature insect stages, like stonefly nymphs, remains challenging.

Purpose of the Study:

• To update the taxonomic knowledge of Perlidae species in the Paranapiacaba Mountains.
• To associate and describe stonefly nymphs using molecular data.
• To contribute to the understanding of stonefly diversity in the region.

Main Methods:

• Field sampling for stonefly collection.
• DNA barcoding for molecular analysis.
• Traditional morphological examination.

Main Results:

• Successfully associated and described the nymphs of Anacroneuria itajaimirim using DNA barcoding.
• Generated DNA barcode sequences for Anacroneuria iporanga.
• Demonstrated the utility of DNA barcoding in identifying immature stonefly stages.

Conclusions:

• DNA barcoding is crucial for associating immature insect stages with adult species.
• Despite previous studies, significant knowledge gaps remain regarding the stonefly fauna of the Paranapiacaba Mountains.
• This research enhances the taxonomic understanding of Perlidae in the region.
