The genus Steindachner, 1867 currently comprises 29 nominal species, some of which are suggested to be cryptic species complexes. The present study was carried out with specimens of the "" clade that encompasses three taxa distributed in the Atlantic Forest biome: Almeida et Angulo, 2006, sp. L., and sp. M. We used classical cytogenetics to describe the diploid number and karyomorphology of these three species collected in two different locations in the state of Bahia, Brazil. Our results revealed the diploid number 2n = 24 (FN = 34) with two pairs of metacentric chromosomes (pairs 1 and 5), three pairs of submetacentric chromosomes (pairs 2, 3, and 4), and seven pairs of telocentric chromosomes (pairs 6, 7, 8, 9, 10, 11, and 12). Further morphological, bioacoustic, and cytogenetic data (C-banding and AgNor) are needed to better delineate the lineages within the "" clade.
施泰因达赫纳属(Steindachner,1867)目前包含29个命名物种,其中一些被认为是隐存物种复合体。本研究以“ ”分支的标本进行,该分支包含分布于大西洋森林生物群落的三个分类单元:阿尔梅达和安古洛,2006,物种L,以及物种M。我们运用经典细胞遗传学方法描述了在巴西巴伊亚州两个不同地点采集的这三个物种的二倍体数目和核型形态。我们的结果显示二倍体数目为2n = 24(FN = 34),有两对中着丝粒染色体(第1和第5对),三对亚中着丝粒染色体(第2、3和4对),以及七对端着丝粒染色体(第6、7、8、9、10、11和12对)。需要更多的形态学、生物声学和细胞遗传学数据(C带和AgNor)来更好地划分“ ”分支内的谱系。
