Abstract

A new genus of Baetidae, Megalabiopsgen. nov., and a new species, M. madagasikarasp. nov., are described from Madagascar based on nymphs. The new genus is characterized by having a strongly enlarged mentum; pedicelli with many long, stout, pointed setae; a brush of dense, short setae between prostheca and mola of both mandibles; an apically pointed maxillary palp with a stout seta at the tip; and a labium with many long, simple setae ventrally on glossae. The patellotibial suture is absent on the fore tibia and present on middle and hind tibiae. The claw is strongly elongated with two rows of denticles. The imago remains unknown and the relationships with other African genera of Baetidae are tentative. Despite being easily identifiable, only two nymphs were found in two highly sampled localities in Madagascar.

马达加斯加一个唇大的新属（蜉蝣目，唇形科）

标题大滨螺科一新属。和一新种madagasikarasp。十一月，是根据马达加斯加的仙女来描述的。新属的特点是有一个强烈扩大的动量;花梗具许多长，粗壮，尖的刚毛;在两个下颚的假骨和臼齿之间的浓密的短刚毛的一刷;顶端尖的上颌触须在顶端具一粗壮的刚毛;唇部在舌骨上有许多长而简单的刚毛。髌胫缝线在胫骨前部没有，在胫骨中部和后部有。爪子长得很长，有两排小齿。这一形象仍然是未知的，与其他非洲贝蒂科属的关系是暂定的。尽管很容易识别，但在马达加斯加的两个高度采样的地方只发现了两个若虫。

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.
