The diploid number 2n = 18 was revealed in Bathybothrium rectangulum, a specific parasite of barbels (Barbus spp.). All chromosome pairs were biarmed (pairs 1, 4, 7, 8, and 9 were metacentric; pairs 2, 3, and 6 were meta-submetacentric; and pair 5 was submetacentric) and small (from 1.49 to 2.95 microm). The C-banding method revealed pericentromeric heterochromatin in pairs 1, 3, 5, and 7; distinct C-bands in pairs 2, 4, 8, and 9; and a slight band in short arms of pairs 1 and 6. The karyotype of B. rectangulum is discussed with respect to the irresolute taxonomic position of B. rectangulum within the Pseudophyllidea.
在须鲃（Barbus spp.）的一种特定寄生虫——矩形深海绦虫（Bathybothrium rectangulum）中，揭示出其二倍体数2n = 18。所有染色体对均为双臂染色体（第1、4、7、8和9对为中着丝粒染色体；第2、3和6对为中-亚中着丝粒染色体；第5对为亚中着丝粒染色体）且体积较小（1.49至2.95微米）。C带染色法显示，第1、3、5和7对染色体存在着丝粒周围异染色质；第2、4、8和9对染色体有明显的C带；第1和6对染色体短臂有轻微带纹。针对矩形深海绦虫在假叶目内不确定的分类地位，对其核型进行了讨论。
