Numerous alien species have been reported in Japanese waters in recent years, but identifications of these species are difficult in most cases. In the Ariake Inland Sea, two new alien gastropods were found in 2000. One of them is Nassarius (Zeuxis) sinarus (Philippi, 1851) from China. This carnivorous species has recently increased explosively in number and has become a pest, eating fish caught in traps. This problem has spread rapidly over wide regions of the Ariake Inland Sea, with goby fisheries using traps in the central and western parts of Saga Prefecture suffering most. Unfortunately, this species was initially misidentified as the endangered species Mitrella martensi (Lischke, 1871). The other alien gastropod species is Stenothyra sp. from Korea. It is an undescribed species in spite of being an alien and had never before been reported from Korea. This case shows that alien species include not only ones that are abundant in their original distribution range, but also unrecognized ones. Several other taxonomic problems posed by alien species are reviewed. Most alien species in Japan have at first been misidentified and/or confused with other species. One of the most important measures to prevent such confusion is the adequate preparation of specimens. Because alien species often appear suddenly, we can not know their origin immediately. If enough specimens are preserved, exact identification may be made through subsequent study. In this connection, alpha-taxonomy will become ever more significant from now on. Comprehensive revisional works for many taxa will be needed in order to identify the alien species.

Previous studies have identified problems with the validity of Self-Esteem IAT (e.g., Falk et al., 2015). One factor contributing to this lack was the low, unstable correlation between Self-Esteem IAT and scales assessing self-esteem (e.g., Karpinski, 2004). Therefore, this study examines whether self-esteem SC-IAT (Kashihara & Shimizu, 2021) would positively correlate with the Self-Esteem Scale scores, even after sample size design and preregistration. The results of this study demonstrated a positive correlation between the Self-Esteem SC-IAT and the Self-Esteem Scale.

Amphidromous gobies of Sicyopterus (Gobiidae: Sicydiinae) are distributed in tropical, subtropical, and temperate streams in the Indo-Pacific region. Two species, Sicyopterus japonicus (Tanaka, 1909) and Sicyopterus lagocephalus (Pallas, 1770), are known from Japan. In the present study, two specimens of an additional species were collected in Okinawa Island, in southern Japan. We compared morphologies of the type series of Sicyopterus longifilis de Beaufort, 1912 and Sicyopterus brevis de Beaufort, 1912 collected in Indonesia, with the specimens from Okinawa Island to revise the taxonomy of these species and to identify the Okinawan specimens. Syntypes of S. longifilis and S. brevis share many characters, including a unique mouth morphology. Although fin morphologies, tooth number, and the shape of the urogenital papilla differ between S. longifilis and S. brevis syntypes, these amount to normal sexual dimorphism of sicydiine gobies. De Beaufort collected his specimens at the same locality on the same date. We conclude that the syntypes of S. longifilis and S. brevis are actually males and females of same species. Therefore, they are subjective synonyms, and we give precedence to the name S. longifilis as the first reviser under Article 24.2 of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999). The two specimens from Okinawa Island were identified as S. longifilis and this is the first record of this species from Japan.
