Abstract

A survey of Sminthurides Börner, 1900 with specimens from the Americas was performed and two new species from Mexico are described and illustrated (drawings and SEM photographs), including a detailed study of body chaetotaxy. Sminthurides cihuatlensis sp. nov. is part of the Aquaticus group by the presence of ciliate seta B1 on Ant. II; it has a narrow mucro and lives in soil from the slopes of Iztaccíhuatl volcano. Sminthurides fridakahloae sp. nov. belongs to the Penicillifer group by the presence of Tra-2 on the Ant. II; it has a broad, trilamellate mucro, dens with plurichaetosis, and lives on surface freshwater from Colima and Morelos states. In addition, a key for the species is provided.

摘要

对来自美洲的 Sminthurides Börner, 1900 进行了调查，并描述和图示了两种来自墨西哥的新物种（绘图和 SEM 照片），包括对体刚毛结构的详细研究。Sminthurides cihuatlensis sp. nov. 是 Aquaticus 组的一部分，因为在 Ant. II 上存在纤毛状的 B1 刚毛；它有一个狭窄的刺，生活在 Iztaccíhuatl 火山斜坡上的土壤中。Sminthurides fridakahloae sp. nov. 属于 Penicillifer 组，因为在 Ant. II 上存在 Tra-2；它有一个宽阔的、三齿状的刺，多刚毛密集，生活在科利马州和莫雷洛斯州的地表水。此外，还提供了一个物种的关键。
