Specimen-based record of Oligotoma humbertiana (Saussure, 1896) (Embioptera, Oligotomidae) from Iriomote Island, Japan, with notes on the species’ distribution and occurrence data

Webspinners (Embioptera) are cosmopolitan but have limited dispersal abilities, and their occurrence data remain poorly documented in Japan. Oligotoma humbertiana (Saussure, 1896), a widely distributed tropical species, has previously been recorded in Japan only from Kyushu and Minamidaito Island, and its occurrence in the Yaeyama Islands has remained uncertain. Here, I report a verifiable specimen-based record from Iriomote Island, based on two winged males collected from a residential building. This finding suggests potential human-mediated dispersal, although local establishment cannot be excluded, and highlights the value of specimen-based data.
