Authors: J Dehling, Ulrich Sinsch

Abstract: We assess the diversity of Ptychadena species in Rwanda based on re-examination of voucher specimens in museum collections and our own data from recent assessment of the species composition of amphibian communities in Rwanda. We recognize five species which we allocate to the following available names: P. anchietae, P. chrysogaster, P. nilotica, P. porosissima, and P. uzungwensis. We did not find evidence for the presence of P. grandisonae and P. oxyrhynchus which have been listed for the country. The five species can be distinguished by quantitative morphometrics (discriminant analysis, success rate: 100 %) and a number of qualitative characters of external morphology. We provide an identification key to the Rwandan species and describe the morphology of each species in detail. The taxonomic status and the phylogenetic position of Ptychadena chrysogaster are further assessed based on the partial sequence of the mitochondrial 16S rRNA. The species differs genetically from available homologous sequences from congeners by an uncorrected p distance of at least 4.2 % and appears to be most closely related to specimens assigned to P. porosissima, P. mahnerti, “P. aff. uzungwensis” and “P. aff. bibroni”.

On new species of Microdiores (Araneae, Zodariidae) from Central and East Africa https://zookeys.pensoft.net/article/2204/ ZooKeys 48: 11-19

DOI: 10.3897/zookeys.48.411

Authors: Benoît Nzigidahera, Rudy Jocqué

Abstract: The distribution of the genus Microdiores Jocque, 1987, so far only known from East Africa, is extended to Central Africa with the description of the new species, Microdiores rwegura sp. n. (♂) and M. violaceus sp. n. (♂♀), both from the Kibira National Park in Burundi. A third new species, M. aurantioviolaceus (♂), from northern Tanzania is described. The status of the genus is confirmed and a key to the males of the species is provided.

An update of Zelotibia (Araneae, Gnaphosidae), a spider genus with a species swarm in the Albertine Rift https://zookeys.pensoft.net/article/1997/ ZooKeys 13: 1-28

DOI: 10.3897/zookeys.13.145

Authors: Benoît Nzigidahera, Rudy Jocqué

Abstract: The spider genus Zelotibia Russell-Smith & Murphy, 2005 is reviewed. Eight new species, all from forest areas in the Albertine Rift, are described: they are Z. angelica (♀), Z. curvifemur (♂♀), Z. fosseyae (♀), Z. johntony (♀), Z. kanama (♀), Z. kibira (♀), Z. lejeunei (♂♀)and Z. subsessa (♀). The unknown female of Z. major Russell-Smith & Murphy, 2005 is described. Z. similis Russel-Smith & Murphy, 2005 is synonymized with Z. paucipapillata Russell-Smith & Murphy, 2005. An illustrated key to the species of the genus is provided. The genus now contains 22 species, 19 of which are concentrated in the Albertine Rift, confirming the biodiversity hot-spot status of that area.
