Anew speciesof the Drosophilamelanicaspecies group isdescribedfrom northern Vietnam. Its metaphase plates of larval ganglion cells showed 2n = 12chromosomes, and this is thelargest number of acrocentric chromosomes in thegroup. Based on karyotype analyses the new species has the most primitive chromosomal configuration in the melanicagroup. Drosophilapengifrom central Japan, once regarded as a synonymof D.tsiganais resurrected as a member of the melanicagroup, based on the results ofcrossing experiments and close morphological examination. Drosophila bisetata from Myanmar and D.longiserratafrom southern China are the new synonym of D.pengi and D. afer, respectively. Themelanicagroup might have emerged in lower geographic latitudesof Asia, diversified along greenbelts of East Asia, and migrated to North America viaBeringia.

描述了产自越南北方的一个果蝇属的新种。其幼虫神经节细胞中期板显示2n = 12条染色体，这是该组中近端着丝粒染色体数量最多的。根据核型分析，该新种具有黑组中最原始的染色体构型。根据杂交实验和近距离形态学观察结果，发现日本中部的果蝇（Drosophilapengi），曾被认为是作为黑类群成员复活的D.tsiganais的一个异名。缅甸的Drosophila bisetata和中国南方的Drosophila longiserrata分别是Drosophila pengi和Drosophila longiserrata的新异名。后，分别。黑色素类群可能起源于亚洲较低的地理纬度，沿着东亚的绿化带沿着多样化，并通过白令山迁移到北美。
