TL: China, Sichuan. Distribution. China: Sichuan. Remarks. This species was described by Maran in 1939 based on a female specimen. The type specimen was deposited in National Museum, Prague, Czech Republic (NMPC). Dr. Martin Fikacek was contacted, but he did not find the type specimen in NMPC, and also did not find any record of rent loans. According to the original description, this species was 3.0 mm long, 1.3 mm wide, strial intervals transversely wrinkled on elytra, and intervals 3, 5, 7, 8 carinate, while the two new species were less than 2.0 mm long, strial intervals smooth and shining on elytra, and interval 8 carinate. This species was also not included in the key because the key was only for males.
