In this paper, new species and of the genus (, ) are described and illustrated. These are: sp. nov. on from Nicaragua and Panama; f. f. nov. on from Panama; f. f. nov. on and from Panama and Trinidad; and f. f. nov. on from Panama. on from Panama as described in 105 (2017) is referred to as f. . Support for these descriptions of species and comes from phylogenetic reconstruction of the large subunit ribosomal DNA and from the application of species delimitation methods (ABGD, bPTP, GMYC). Host specialization results in phylogenetic segregation by host species in both and and this may represent a case of incipient speciation. A second mechanism driving diversity involves position-induced morphological adaptations, leading to the peculiar morphotypes that are associated to growing on a particular position of the integument ( f. , f. ).
在本文中,描述并说明了 属( , )的新物种和变型。它们分别是:来自尼加拉瓜和巴拿马的 上的 新种;来自巴拿马的 上的 新变型;来自巴拿马和特立尼达的 和 上的 新变型;以及来自巴拿马的 上的 新变型。如《 》105(2017)中所述的来自巴拿马的 上的 被称为 变型。对这些物种和变型描述的支持来自大亚基核糖体DNA的系统发育重建以及物种界定方法(ABGD、bPTP、GMYC)的应用。宿主专一性导致在 和 中按宿主物种进行系统发育隔离,这可能代表了一个初始物种形成的案例。驱动多样性的第二种机制涉及位置诱导的形态适应,导致与在体表特定位置生长相关的特殊形态类型( 变型, 变型)。
