Abstract

A recent survey of earthworms carried out in South East Madagascar resulted in collecting two species belonging to the endemic Malagasy earthworm genus Howascolex Michaelsen, 1901. One of the species proved to be identical to the generotype Howascolex madagascariensis Michaelsen, 1901. The other spe cies Howascolex farafangana sp. n. represents the second species of the genus. The genus Howascolex was originally classified in the subfamily Octochaetinae Michaelsen, 1900. However, its close morphological similarity with the Malagasy acanthodriline species implies a homoplasious origin of the meroic excretory system of Howascolex and its inclusion in the family Acanthodrilidae Claus, 1880.

马达加斯加特有蚯蚓属Howascolex Michaelsen第二种，1901;Howascolex farafangana sp. n (Clitellata, Megadrili)

最近在马达加斯加东南部进行的一项蚯蚓调查收集了两个属于马达加斯加特有蚯蚓属Howascolex Michaelsen(1901年)的物种。其中一种被证明与1901年发现的Howascolex madagascar ensis Michaelsen属型相同。另一种Howascolex farafangana sp. n.代表该属的第二种。Howascolex属最初被划分在八爪蛛亚科(Octochaetinae)， Michaelsen, 1900。然而，它与马达加斯加棘果碱物种在形态上的密切相似性暗示了Howascolex的分生排泄系统的同源起源，并将其纳入棘果碱科(Claus, 1880)。

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.
