 The genus Adenomera 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 “thomei” clade that encompasses three taxa distributed in the Atlantic Forest biome: Adenomera thomei Almeida et Angulo, 2006, Adenomera sp. L., and Adenomera 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 “thomei” clade.

“thomei”进化枝中 Adenomera Steindachner,1867(Anura,Leptodactylidae)物种的首次核型描述

 Adenomera Steindachner 属,1867 年目前包括 29 个标称物种,其中一些被认为是神秘物种复合体。本研究是使用“thomei”进化枝的标本进行的,该进化枝包含分布在大西洋森林生物群落中的三个分类群:Adenomera thomei Almeida et Angulo,2006,Adenomera sp。L. 和 Adenomera sp。M. 我们使用经典细胞遗传学来描述在巴西巴伊亚州的两个不同地点收集的这三个物种的二倍体数量和核形态学。我们的结果揭示了二倍体数 2n = 24 (FN = 34),具有两对中心染色体(第 1 和 5 对)、三对亚中心染色体(第 2、3 和 4 对)和七对远心染色体(对6、7、8、9、10、11 和 12)。进一步的形态学,生物声学,
