Eurysternus caribaeus was analyzed cytologically by conventional chromosomal staining. The species presents a diploid number of 2n=8, chromosomes with two arms and an XY sex determining mechanism. This is the first karyotype described for the genus Eurysternus and the tribe Eurysternini, and is also the smallest diploid number observed in the family Scarabaeidae and superfamily Scarabaeoidea.
通过传统染色体染色对加勒比阔胸犀金龟进行了细胞学分析。该物种的二倍体数为2n = 8，染色体有两条臂，具有XY性别决定机制。这是阔胸犀金龟属和阔胸犀金龟族描述的首个核型，也是在金龟科和金龟总科中观察到的最小二倍体数。
