A review of Solenysa spiders from Japan (Araneae, Linyphiidae), with a comment on the type species S. mellotteei Simon, 1894

The present paper gives a review of Solenysa species from Japan and provides a solution for the species bearing the generotype name Solenysamellotteei Simon, 1894. A total of six species are recorded, including two new species Solenysamacrodonta sp. n. and Solenysatrunciformis sp. n. The species collected from Kawasaki (NSMT-Ar 11154) and Hachioji should be the generotype Solenysamellotteei, with Solenysaakihisai Tu, 2011, syn. n. as its junior synonym. To distinguish these congeneric species from each other, their genital characters are provided in detail based on images collected by scanning electron microscopy and light microscopy.
