The anatomy of Microplana termitophaga from Zimbabwe and Kenya: confirmation of the subfamily and genus

Abstract

Microplana termitophaga has been observed feeding on termites in Harare, Zimbabwe. In small specimens the pharynx is about two-thirds of the way along the body, but in large specimens the pharynx is only one quarter of the way along the body. Details of the subepidermal musculature of specimens from Kenya and Zimbabwe are described which confirm the previously uncertain assignment of the species to the subfamily Microplaninae. Sexually mature specimens are found towards the end of the wet season in Zimbabwe. The anatomy of the reproductive system is described. The gonopore is about two-thirds of the way along the body in mature specimens, but sexual maturity seems not to be related simply to size. There is a genito-intestinal duct which confirms that the species is of the genus Microplana.
