Karyotypic analyses of 366 specimens of the solitary wasp Trypoxylon (Trypargilum) albitarse collected from ten populations in the municipalities of Viçosa and Porto Firme (Minas Gerais, Southeastern Brazil), revealed the presence of two morphological types of supernumerary (B) chromosomes. C-banding and fluorochrome banding suggest that the B chromosomes of T. albitarse may have originated from heterochromatin breaks within the standard (A) chromosome complement.
对从维索萨市和波尔图菲姆市（巴西东南部米纳斯吉拉斯州）的十个种群采集的366只独居黄蜂白跗三锥象（Trypoxylon (Trypargilum) albitarse）标本进行的核型分析显示，存在两种形态类型的超数（B）染色体。C带和荧光带分析表明，白跗三锥象的B染色体可能起源于标准（A）染色体组内的异染色质断裂。
