This study highlights the species diversity of Ceratopogonidae from the Paranaense forest and adjacent grassland in a protected natural area of Argentina, and emphasizes the importance of conserving the last remaining marginal forest area surrounded by a strong urbanization. A total 46 species belonging to 10 genera were recorded from these two habitats. Species diversity was higher in the grassland, while dominance was greater in the forest. Twelve species were abundant, while the rest were scarce or rare. The composition of the ceratopogonid community differs between habitats: 15 species were exclusive to the forest, 4 to the grasslands, and 27 used both habitats indistinctly. Differences between habitats were observed in the abundances of Alluaudomyia schnacki Spinelli, Atrichopogon albinensis Ingram and Macfie, and Forcipomyia rioplatensis Marino and Spinelli. The sex ratio of the most abundant species did not show a definite pattern in relation to the habitats, except for Culicoides caridei (Brèthes), in which females were dominant. Atrichopogon balseiroi Spinelli and Forcipomyia williamsi Marino & Spinelli have only been recorded in Buenos Aires Province and were found exclusively in the forest during this study.

受城市化威胁的保护区中的角棘科（双翅类）社区。

这项研究强调了阿根廷受保护的自然保护区中巴拉那森森林和邻近草地中的角柏科的物种多样性，并强调了保护最后一个被强烈城市化包围的边缘森林的重要性。这两个栖息地共记录了属于10属的46种。草地的物种多样性更高，而森林的优势更大。十二种物种丰富，其余物种稀少或稀有。各个栖息地之间的角藻类群落组成不同：森林专有的有15种，草原具有4种，两种栖息地的27种都不清楚。在的丰度，观察到的生境之间的差异Alluaudomyia schnacki斯皮内利，Atrichopogon albinensis英格拉姆（Ingram）和麦菲（Macfie），以及里弗普里米奥（Forcipomyia rioplatensis）马里诺（Marino）和斯皮内利（Spinelli）。除了雌性居于主导地位的库里鳄（Culicoides caridei）（Brèthes）外，最丰富物种的性别比相对于栖息地没有确定的模式。仅在布宜诺斯艾利斯省才记录到芦荟，刺梨和Forcipomyia williamsi Marino＆Spinelli，并且在本研究中仅在森林中发现它们。
