Diagnosis.
See Tu et al. (2007).
Description.
Habitus of male as in Fig. 6 E, habitus of female as in Fig. 6 F. Palp as in Fig. 6 A-D, embolic division as in Fig. 11 A, B; epigyne and vulva as in Fig. 6 G-J. See Tu et al. (2007) for a detailed description.
Type locality.
Shimo-kajiwara Itsuki-mura, Kuma-gun, Kumamoto Prefecture, Kyushu, Japan. (32.200°N, 130.500°E)
Remarks.
The current known distribution of S. reflexilis covers Kyushu (Nagasaki, Kumamoto, Ōita, and Kagoshima Prefectures) with additional records from Shikoku (Tokushima and Ehime Prefectures), and the Chugoku area in Western Honshu (Shimane Prefecture), Japan (Shinkai et al. 2024, this work) (Fig. 13). Our new data confirm the presence of S. reflexilis in southern Kyushu, particularly in mainland Kagoshima Prefecture and on the island of Yakushima, where this species has been recently reported by Shinkai and Tanikawa (2023). Previous records of this species in northern and eastern Kyushu should be replaced by the closely related S. bilamellata sp. nov. The record from Ōita prefecture by Serita (2022) might refer to a misidentification of the similar S. bilamellata sp. nov. Records from Shimane Prefecture (Hayashi et al. 2013 a, b) and Shikoku Island (Tsurusaki et al. 2011, 2012; Bando 2015, 2019), all except one, predate the revision of the Japanese Solenysa species by Wang et al. (2015) and the description of S. macrodonta and S. trunciformis. Samples published by Bando (2015) examined by us all refer to S. trunciformis. Due to the possibility of misidentifications with other closely related and morphologically similar species endemic to the same areas, the presence of S. reflexilis in Eastern Kyushu, Western Honshu, and Shikoku, remains unclear and should be properly validated based on more recent evidence. Similarly, the precise boundaries between the ranges of S. reflexilis and S. bilamellata sp. nov. in Kyushu are unknown and should be addressed in more detail.
