“…Similar patterns were also found in South Korea, but only between epigean populations. Unlike studies from North America, studies of Korean leptonetids have focused on α-level diversity, treating cases of polymorphism as a separated species 2,3,7,22,23 .…”

Leptonetidae are tiny and rarely encountered spiders, mainly inhabiting moist environments such as caves, leaf litter, and rock piles. Because they are microhabitat specialists, most species are known to have short range endemism, rarely occurring in sympatry. Due to their small size, relatively simple features of habitus and structure of reproductive organs made it challenging on sufficient identification. Not only leptonetids, but also identification in other spiders having sexual dimorphism, polymorphism, and lack of diagnosable keys in juvenile made it even more time consuming. To overcome these obstacles, DNA barcoding has been used as an effective tool for species identification. Herein, we conducted a test of DNA barcoding with Korean Leptonetidae based on 422 specimens representing 76 morphospecies. A threshold of 4.2% genetic divergence was estimated to differentiate the morphological species efficiently. The species assignments tested by five species delimitation methods (ABGD, ASAP, GMYC, PTP, and bPTP) were consistent with morphological identifications for 49 species (64.5%), indicating many cases of cryptic diversity. Further, sympatry in leptonetids was revealed to be common in South Korea, especially in epigean species. Our results showed sympatries no matter within family, congeners, and interclade potentially occurring throughout the entire region of the Korea.

Leptonetidae are tiny, rarely encountered spiders that mainly inhabit moist environments, such as caves, leaf litter, and rock piles. Because they are microhabitat specialists, most leptonetid species have short-range endemism, and rarely occur in sympatry. Their small size, relatively simple habitus features and reproductive organ structure increase the difficulty of identification. The identification of leptonetids and other spiders may also be time-consuming due to their sexual dimorphism, polymorphism, and lack of diagnostic characteristics in juveniles. DNA barcoding has been used as an effective tool for species identification to overcome these obstacles. Herein, we conducted a test of DNA barcoding based on 424 specimens of Korean Leptonetidae representing 76 morphospecies. A threshold of 4.2% based on maximum intraspecific genetic divergence was estimated to efficiently differentiate the morphospecies. The species assignments tested by five species delimitation methods (ABGD, ASAP, GMYC, PTP, and bPTP) were consistent with the morphological identifications for only 47 morphospecies (61.8%), indicating many cases of cryptic diversity among the remaining morphospecies. Furthermore, sympatry in leptonetids, which are known to be rare, was revealed to be common in South Korea, especially in epigean species. Our results showed that sympatries within families, congeners, and intraclades potentially occur throughout the entire region of Korea.
