摘要

摘要我们提供了来自巴西巴伊亚州伊皮拉市的神秘的阿努兰Xenohyla优生学的广告呼叫和核型数据。广告呼叫由持续时间为0.111±0.015 s的单个多脉冲音符形成，主频为1033.6–2873.6 Hz，沿两个频段。该种有2n=24条染色体，基数=48。DAPI染色显示所有染色体的着丝粒位置都有阳性标记，而使用端粒探针的FISH标记所有染色体末端。这些数据揭示了该属的进化史，并有助于了解其姊妹属松毛虫的进化方面。

Advertisement Call and Cytogenetics of Xenohyla eugenioi Caramaschi, 1998 (Amphibia; Anura; Hylidae), an Enigmatic Frog from Northeastern Brazil

Abstract. We provide data on the advertisement call and karyotype of the enigmatic anuran Xenohyla eugenioi from the municipality of Ipirá, State of Bahia, Brazil. The advertisement call is formed by a single multi-pulsed note of 0.111 ± 0.015 s of duration and with dominant frequency of 1033.6–2873.6 Hz along two bands. The species presents 2n = 24 chromosomes and fundamental number = 48. DAPI staining revealed positive labeling on centromeric position in all chromosomes, while FISH using telomeric probe labeled all chromosomal ends. These data shed light on the evolutionary history of the genus and contribute to understanding evolutionary aspects of its sister genus Dendropsophus.
