Two species of the genus Valenzuela (Psocodea, Psocomorpha, Caeciliusidae), newly recorded from South Korea

The genus Valenzuela Navás, 1924 (Psocodea, Psocomorpha, Caeciliusidae) currently comprises 297 extant species worldwide. However, only one species, Valenzuela oyamai (Enderlein, 1906), has previously been recorded from South Korea. Further examination of specimens collected in the country is needed to improve knowledge of the national fauna and provide morphological references for species identification. In this study, psocid specimens collected from several localities in South Korea between 2023 and 2025 were examined to document additional species of Valenzuela and their diagnostic characters. Valenzuela badiostigma (Okamoto, 1910) and Valenzuela flavidus (Stephens, 1835) are recorded from South Korea for the first time, increasing the number of Valenzuela species known from the country from one to three. Descriptions and measurements, based on Korean specimens, are provided, together with illustrations of diagnostic characters and information on collection localities and geographical distribution. An identification key to the three Valenzuela species currently known from South Korea is also presented. These records update the national inventory of the genus and provide reference material for subsequent taxonomic studies and faunistic surveys.
