A new species from the cockroach genus Eucorydia Hebard, 1929 from Miyako-jima Island of the Nansei Islands in Southwest Japan was compared to six closely related congeners; E. yasumatsui Asahina, 1971; E. donanensis Yanagisawa, Sakamaki, and Shimano, 2020; E. tokaraensis Yanagisawa, Sakamaki, and Shimano, 2020; E. dasytoides (Walker, 1868); E. guilinensis Qiu, Che, and Wang, 2017; and E. pilosa Qiu, Che, and Wang, 2017. The new species Eucorydia miyakoensis Yanagisawa, Sakamaki, and Shimano, sp. nov. from Miyako-jima Island was characterized by a small overall male body length of 12.5–13.0 mm and tegmina with an uninterrupted orange transversal band in the middle, and a pair of orange pubescent patches at the base. Eucorydia yasumatsui, E. donanensis, E. tokaraensis, the zonata population of E. dasytoides, and E. miyakoensis were divided into five lineages in a maximum likelihood tree generated from a dataset concatenated from five molecular markers (two nuclear: 28SrRNA and histone H3, and three mitochondrial: COII, 12SrRNA, and 16SrRNA). We recognized E. miyakoensis as a distinct species, which was also supported by the pairwise genetic distances (3.4%–6.7%, K2P) of the COI sequences to the other Japanese Eucorydia species.

We describe a new species of marine associated oribatid mite, Ameronothrus twitter Pfingstl and Shimano, sp. nov., from a wharf of fishing port (Choshi Outer Fishing Port), Chiba, Honshu, Japan. This species was spotted for the first time ever on photographs posted on Twitter. Ameronothrus twitter Pfingstl and Shimano, sp. nov. is characterized by a specific cuticular notogastral pattern consisting of distinct nodules that are fused to irregular ridges in the median anterior and the median posterior region. Additionally, it features a unique combination of fused lamellar keels, presence of primilateral setae on tarsus I, presence of dorsal companion setae on genu I, II, III and all tibiae and tarsal distal setae ending with a small nodule. Ameronothrus twitter Pfingstl and Shimano, sp. nov. is the second species of this genus found on Japanese islands, which represents the southernmost occurrences of this taxon in the Asian Pacific region.
