摘要

在过去十年中,短头龙的描述物种数量迅速增加(n=22,占总数的56%)。Brachychalus属的物种大多分布在从巴伊亚州(巴西东北部)到圣卡塔琳娜州(巴西南部)的孤立山顶上,每一种都只占据一个或几个相邻的山顶。在此,我们描述了来自圣卡塔琳娜州Serra do Tabuleiro的B.pernix群短头藻的一个新种,它也是已知最南端的物种。该新种与同类的区别主要表现在以下几个方面:(1)蟾蜍形体;(2) 小型成年SVL:9.57–11.10 mm(雄性)和10.88–12.70 mm(雌性);(3) 头部比例较小(HL/SVL 19-28%),眼睛比例较大(ED/HL 36-56%);(4) 背纹理粗糙;(5) 吻的形状圆形的背面和侧面视图;(6) 全身背侧体色橄榄绿,头部、手臂和腿部为黄橙色,散布橄榄绿,脊椎有橙色条纹,斑点为白色和棕色;(7) 颅骨和骨骼无骨质增生;(8) 额顶和蝶窦未融合;(9) 带有一个或两个高频音符(6115–6562 Hz)的广告,每个音符有2-4个脉冲。该地区毗邻保护区Parque Estadial da Serra do Tabuleiro,但我们观察到该地区的各种农业活动,包括外来植物的存在,这些植物会改变落叶的数量和质量,以某种方式影响新物种的数量。另一个恶化因素是,São Bonifácio市在土地使用问题上存在冲突,在Parque Estadoil da Serra do Tabuleiro有非正常占用和未完成的征用程序。考虑到Brachychalussp。nov.很可能是一个山顶微流行物种,未来的研究量化新物种的完整分布和评估种群趋势,以准确评估其保护状况至关重要。

A new species of Brachycephalus (Anura: Brachycephali­dae) from Serra do Tabuleiro, Southern Brazil
The number of described species of Brachycephalus has rapidly increased in the last decade (n = 22, which represents 56% of the total). Species of the genus Brachycephalus are mostly distributed in isolated mountaintops from Bahia (northeastern Brazil) to Santa Catarina states (southern Brazil), each one occupying only one or a few adjacent mountaintops. Herein, we described a new species of Brachycephalus of the B. pernix group, from Serra do Tabuleiro in Santa Catarina state, which also represents the southernmost known species. The new species can be distinguished from its congeners by a combination of characters, including the following: (1) “bufoniform” body; (2) small adult SVL: 9.57–11.10 mm for males and 10.88–12.70 mm for females; (3) head proportionally small (HL/SVL 19–28%) and eye proportionally large (ED/HL 36–56%); (4) dorsum texture rough; (5) snout shape rounded in dorsal and lateral views; (6) general dorsal body color olive green with head, arms and legs yellow-orangish scattered with olive green, and an orangish vertebral stripe spotted with white and brown colors; (7) skull and skeleton without hyperossification; (8) frontoparietal and sphenethmoid not fused; (9) advertisement with one or two high-frequency notes (6,115–6,562 Hz), and 2–4 pulses per note. The type locality is adjacent to Parque Estadual da Serra do Tabuleiro, a protected area, but we observed various agricultural activities in this locality, including the presence of exotic plants, which can change the amount and the quality of leaf litter, somehow compromising the population of the new species. Another aggravating factor is that the municipality of São Bonifácio has conflicts over land use with irregular occupation and unfinished expropriation processes in Parque Estadual da Serra do Tabuleiro. Considering that Brachycephalussp. nov. is probably a mountaintop microendemic species, it is paramount that future studies quantifying the new species’ full distribution and evaluating population trends to accurately assess its conservation status.
