“…The distribution of NORs was only studied in M. fuliginosus from Japan (Ono and Obara, 1994) and was similar to M. medius (this work). An exception from this remarkable karyotype conservation was found in a Thai population of M. s. fuliginosus, where an acrocentric autosomal pair from the 'standard' karyotype (Harada et al, 1985) was shown to harbor a heterochromatic short arm, while the description of an additional metacentric autosomal pair for M. africanus in another report (Tolera et al, 2021) may be related to misidentification of the X chromosome.…”
