Abstract
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) vadersp. nov. and Leptopsis (Leptopsis) silenssp. 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) guyanensiscomb. 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.
