3.2. Taxonomie und Faunistik

De Nicéville (1890: 213-214) nannte erst einmal "Habitat: Burma, Malay Peninsula", später aber: "The type specimen from I. iapis is from Johore in tthe Malay Peninsula." Chiba et al. (2026) stellten fest: "our genomic analysis definitively supports the distinction of Isma iapis (de Nicéville, 1890) (type locality in Malaysia: Johor) as a species (Fig. 2), e.g., the COI barcodes I. iapis and I. protoclea differ by 8.7% (57 bp), and the two species are broadly sympatric (Evans 1949)."
