Identification of Parathelphusa sp. in the Catchment Area of Lake Matano, South Sulawesi, Using Classical Taxonomy and DNA Barcoding
Abstract
The study aimed to identify and classify Parathelphusa sp. in Lake Matano using classical taxonomy and DNA barcoding. It included morphological and morphometric analysis, alongside molecular analysis with the Cytochrome Oxidase Subunit I (COI) gene and NCBI GenBank BLAST Nukleotida Standard. The results revealed two morphotypes, one identified as Parathelphusa pantherine, while the second remained unidentified despite resembling Parathelphusa pallida. This research underscores the value of combining DNA barcoding and classical taxonomy (morphological and morphometric) for species identification, offering new insights into the genetic diversity of Parathelphusa crabs in Lake Matano, supports conservation, ecosystem management, and protection of endemic species.
