摘要

根据幼虫，描述了几内亚（西非）的一个Baetidae新属Pedicelliops gen.nov.和一个新种P.capillifer sp.nov。这个新属的特征是有明显增大的足蒂和非常短的鞭毛，在两个下颚的前颚和莫拉之间有一刷密集的短刚毛，一个小的矩形唇，一个顶端尖的上颌须，一个唇须，有一个小外侧突起，舌片和舌旁腹部有长刚毛。所有腿的股骨上都覆盖着许多细长的刚毛。髌胫缝合线在胫骨前部缺失，在胫骨中部和后部存在。爪子尖上有两排小齿。腹部趾后缘无棘。imago仍然未知，与Baetidae的其他非洲属的关系仍然未知。尽管很容易识别，体型也相当大（体长约5毫米），但在西非的两个高度采样的地方只发现了两种幼虫。

Pedicelliops gen. nov., a new genus from West Africa with striking antennae (Ephemeroptera, Baetidae)

A new genus of Baetidae, Pedicelliops gen. nov., and a new species, P. capillifer sp. nov., are described from Guinea (West Africa) based on larvae. The new genus is characterized by having strongly enlarged pedicelli and very short flagella, a brush of dense, short setae between prostheca and mola of both mandibles, a small rectangular labrum, an apicolaterally pointed maxillary palp, a labial palp with a small distolateral protuberance and long setae ventrally on glossae and paraglossae. The femora of all legs are covered with numerous long, fine setae. The patellotibial suture is absent on the fore tibia and present on middle and hind tibiae. The claw is pointed with two rows of denticles. No spines are present on the posterior margins of the abdominal tergites. The imago remains unknown and the relationships with other African genera of Baetidae remains tentative. Despite being easily identifiable and of a fairly large size (body length ca. 5 mm), only two larvae were found in two highly sampled localities in West Africa.

期刊介绍： African Invertebrates is an international peer-reviewed, open-access journal that focuses primarily on the taxonomy, systematics, biogeography, and palaeontology of Afrotropical invertebrates, whether terrestrial, freshwater or marine. Aspects concerning biology, ecology, and conservation may also be considered where these relate to the primary focus areas. Papers dealing solely with biology, ecology, physiology, pests and pest control should be submitted elsewhere.
