Cytochrome c oxidase subunit 1 (Coi) profile of the philippine helicostylinae (gastropoda: Stylommatophora: Camaenidae)

Abstract

© 2019, Department of Science and Technology. All rights reserved. The Philippines is the center of radiation of the land snail subfamily Helicostylinae, with around 253 recognized species. Despite their morphological diversity, research on their biology and taxonomy is lacking. We present here the first mitochondrial COI profiles of 32 species of Philippine helicostyline land snails. With the addition of sequences downloaded from GenBank, we tested the utility of the COI for species identification. Relative distributions of intraspecific and interspecific distances overlapped; hence, no barcoding gap was observed. However, 90% of uncorrected interspecific comparisons can distinguish species at 14% genetic distance or lower. Furthermore, the COI barcodes could not discriminate several co-distributed species that have similar conchological features, which should be flagged for taxonomic re-evaluation.
