摘要

Leptopsis （Leptopsis）是南美洲的一个属，有两个亚属和七个有效种：Leptopsis (Leptopsis) Desutter-Grandcolas, 1996，包括Leptopsis (Leptopsis) nauta Desutter-Grandcolas, 1992, Leptopsis (Leptopsis) zumun Desutter-Grandcolas, 1992, Leptopsis (Leptopsis) saussurei Desutter-Grandcolas, ecuadori Gorochov, 2006，和Leptopsis (Leptopsis) ucayali Gorochov, 2011；和Leptopsis (Aberracla) Gorochov, 2011，包括Leptopsis (Aberracla) chopardi Desutter-Grandcolas， 1992和Leptopsis (Aberracla) morona Gorochov, 2011。本文描述了在巴西par州首次记录到的Leptopsis (Leptopsis) vader sp. nov和Leptopsis (Leptopsis) silens sp. nov两个新种，并通过物种分布模型（SDMs）对该属的分布进行了预测和讨论。这两个新物种很容易通过生殖器复合硬膜的形状与其他物种区分开来，特别是假阴茎硬膜a。此外，雌性在这些结构已知的物种之间表现出交配乳头的差异。我们还建议将Mellomima Desutter-Grandcolas， 2020同义命名为Leptopsis (Aberracla)，将属级降为亚属，并将Mellomima guyanensis Desutter-Grandcolas， 2020移至Leptopsis （Aberracla）组合下的Leptopsis (Aberracla) guyanensis梳子下的Leptopsis （Aberracla）亚属。11 . Leptopsis属的SDMs显示出合理的拟合，尽管该属目前的分布有限。该模型表明，亚马逊河流域中部和北部分布广泛，东部地区覆盖范围最大。在委内瑞拉、圭亚那和苏里南等尚未记录该属的国家也确定了高适宜性地区。此外，该模型还预测了亚马逊地区以外的高适宜性地区，特别是哥伦比亚北部和委内瑞拉。对模式贡献最大并可能影响属分布的生物气候变量是最湿季降水和等温线。

Two new species of Leptopsis Desutter-Grandcolas, 1996 (Orthoptera: Phalangopsidae: Phalangopsinae) from the Brazilian Amazon rainforest with insights from potential distribution models for the genus

Leptopis is a South-American genus with two subgenera and seven valid species: Leptopsis (Leptopsis) Desutter-Grandcolas, 1996, including Leptopsis (Leptopsis) nauta Desutter-Grandcolas, 1992, Leptopsis (Leptopsis) zumun Desutter-Grandcolas, 1992, Leptopsis (Leptopsis) saussurei Desutter-Grandcolas, 1992, Leptopsis (Leptopsis) ecuadori Gorochov, 2006, and Leptopsis (Leptopsis) ucayali Gorochov, 2011; and Leptopsis (Aberracla) Gorochov, 2011, including Leptopsis (Aberracla) chopardi Desutter-Grandcolas, 1992, and Leptopsis (Aberracla) morona Gorochov, 2011. In this work, we describe two new species, Leptopsis (Leptopsis) vader sp. nov. and Leptopsis (Leptopsis) silens sp. nov, recorded in the state of Pará, Brazil, the first record of the genus in the country, and predict and discuss the distribution of the genus through Species Distribution Models (SDMs). These two new species are easily distinguished from the others by the shape of the phallic complex sclerites, specifically the pseudepiphallic sclerite A. Additionally, the females exhibit differences in copulatory papillae among species for which these structures are known. We also propose synonymizing Mellomima Desutter-Grandcolas, 2020 under Leptopsis (Aberracla), lowering the rank from genus to subgenus, and moving Mellomima guyanensis Desutter-Grandcolas, 2020 to the subgenus Leptopsis (Aberracla), under the combination Leptopsis (Aberracla) guyanensis comb. nov. The SDMs for the genus Leptopsis showed a reasonable fit despite the genus's current limited distribution. The model indicated a wide distribution across central and northern Amazonia, with the greatest coverage in the eastern region. High-suitability areas were also identified in countries where the genus has not yet been recorded, such as Venezuela, Guyana, and Suriname. Furthermore, the model predicted high-suitability regions outside Amazonian domains, particularly in northern Colombia and Venezuela. The bioclimatic variables that contributed most to the models and probably influence the genus distribution were the precipitation of the wettest quarter and isothermality.

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
