Abstract

Abstract The genus Kinosternon in Mexico is represented by 12 species of which only 2 inhabit the lowlands of the central Pacific region (Kinosternon chimalhuaca and Kinosternon integrum). Based on 15 standard morphological attributes and coloration patterns of 9 individuals, we describe a new microendemic mud turtle species from the central Pacific versant of Mexico. The suite of morphological traits exhibited by Kinosternon sp. nov. clearly differentiates it from other species within the genus Kinosternon by a combination of proportions of plastron and carapace scutes, body size, and a large yellow rostral shield in males. The new species inhabits small streams and ponds in and near the city of Puerto Vallarta, Jalisco. Unfortunately, natural populations are unknown so far. The habitat is damaged by urban growth, and only one female is known. The available information would suggest that Kinosternon vogti sp. nov., is one of the most threatened freshwater turtle species. An urgent conservation program is necessary as well as explorations in the area to find viable populations of the species.

青海西部一独特的泥龟新种

墨西哥的Kinosternon属共有12种，其中仅有2种(Kinosternon chimalhuaca和Kinosternon integrum)分布在太平洋中部的低地。根据9个个体的15个标准形态特征和颜色模式，描述了墨西哥中太平洋地区的一种新的微特有泥龟。Kinosternon sp. nov.表现出的一系列形态特征，通过结合板甲和甲壳鳞片的比例、身体大小和雄性大的黄色吻盾，明显地将其与Kinosternon属的其他物种区分开来。这种新物种栖息在哈利斯科州巴亚尔塔港市及其附近的小溪和池塘里。不幸的是，到目前为止，自然种群尚不清楚。城市的发展破坏了它们的栖息地，目前已知只有一只雌性。现有的信息表明，Kinosternon vogti sp. nov.是最受威胁的淡水龟物种之一。一项紧急的保护计划是必要的，同时在该地区进行探索，以找到该物种的生存种群。

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
