Abstract

During an ongoing project aiming to understand the dynamics of Ephemeroptera biodiversity in the Doce River Basin after the disaster, an unusual large number of Apobaetis Day, 1955 were analyzed. The occurrence of Apobaetis is quite relevant, since the combination of factors such as its small body size and its habitat preferences makes their collection difficult and its presence often neglected. For the first time in science, adults of Apobaetis irai De Lima, Massariol, Cruz & Hamada, 2022 and Apobaetis fiuzai Salles & Lugo-Ortiz, 2002 are described and diagnosed. Apobaetis irai can be easily distinguished, among other characteristics by turbinate portion of compound eyes touching each other along midline; abdominal terga II-III and V-VII with well-marked lines on lateral and posterior margins; posterior margin of subgenital plate with projection broadly rounded to slightly truncate. Apobaetis fiuzai are diagnosed by turbinate portion of compound eyes touching each other posteriorly; mesothorax brown, except for broad cream marks on anterior margin of PSp and SLS, SSLi tinged with white, posterior corner of SMS with a red spot; abdominal terga II-VI translucent orangish-brown, terga VII-X brown, terga II-III and VI with conspicuous red medial mark; posterior margin of subgenital plate with subtriangular projection, apex narrowly truncate; forceps base wider at base, inner irregular edges. The new records of A. irai and A. fiuzai extend the distribution of Apobaetis within Minas Gerais and Espírito Santo States, Brazil. Furthermore, it is reported for the first time cases of gynandromorphs for Apobaetis.

减少 Apobaetis Day,1955 年(蜉蝣目:Baetidae)的 Wallacean 和 Haeckelian 缺陷。
目前正在进行的一个项目旨在了解多塞河流域灾后蜉蝣类生物多样性的动态,在该项目中,对 1955 年出现的大量 Apobaetis Day 进行了分析。Apobaetis的出现具有相当重要的意义,因为其体型小和对栖息地的偏好等综合因素使其难以采集,其存在往往被忽视。科学界首次描述并诊断了Apobaetis irai De Lima, Massariol, Cruz & Hamada, 2022年和Apobaetis fiuzai Salles & Lugo-Ortiz, 2002年的成虫。除其他特征外,Apobaetis irai 很容易区分,复眼的甲状突起部分沿中线相互接触;腹部第 II-III 和第 V-VII 背片的侧缘和后缘有清晰的标记线;亚生殖板后缘的突起呈宽圆形或稍截形。Apobaetis fiuzai 的诊断方法是复眼的甲状突起部分在后方相互接触;中胸褐色,但 PSp 和 SLS 的前缘有宽的奶油色痕迹,SSLi 染有白色,SMS 的后角有红色斑点;腹部第 II-VI 背片半透明橙褐色,第 VII-X 背片褐色,第 II-III 背片和第 VI 背片中间有明显的红色斑纹;亚属板后缘有近三角形突起,先端狭截形;镊子基部较宽,内部边缘不规则。新记录的 A. irai 和 A. fiuzai 扩大了 Apobaetis 在巴西米纳斯吉拉斯州和圣埃斯皮里图州的分布范围。此外,这是首次报道雌雄同体的 Apobaetis。
