Taxonomic Notes on the Genus Sinopoda (Araneae, Sparassidae), with Descriptions of Two New Species from Korea

Abstract

The genus Sinopoda (Araneae, Sparassidae) from Korea are taxonomically reviewed. As a result, Sinopoda aureola is removed from the synonymy of Sinopoda stellatops and treated as a valid species. In addition, two new species, Sinopoda biguttata sp. nov. and Sinopoda nigrobrunnea sp. nov. are described with accompanying photographs. The new species, S. biguttata sp. nov., can be distinguished from other congeners by the combination of following characteristics: a pair of large ivory patterns near posterior muscle sigilla on opisthosoma; relatively small internal genitalia and long, distally bifurcated fertilization duct. The new species, S. nigrobrunnea sp. nov., can be distinguished from other congeners by the combination of following characteristics: lateral edge of epigyne angled; edge of epigynal pocket linear; glandular appendages perpendicularly directed then curved posteriorly.

Taxonomic study on Sinopoda Jäger, 1999 (Araneae, Sparassidae, Heteropodinae), with three new species from Korea

“…The endemic species diversity of Korean Sinopoda had been noted by some small studies describing five additional new species before 2015 (Kim et al , 2014Kim and Ye 2015), but four of them, viz, Sinopoda clivus , Sinopoda jirisanensis , Sinopoda aureola Kim, Lee & Lee, 2014, and Sinopoda yeoseodoensis Kim & Ye, 2015 were synonymized with previously known species in a checklist of Korean spiders (Yoo et al 2015). However, Lee et al (2016) noted that the synonymization was not clearly justified since taxonomic notes on their treatment was not provided, and primarily revalidated S. aureola and provided descriptions of two new species. According to that study, the other three previously synonymized species could also be removed from their respective senior species.…”
