The Afrotropical species of the genus Paralimosina L. Papp, 1973, are discussed. Six new species, Paralimosina australis sp. n. (Rwanda, Burundi, South Africa), P. congoensis sp. n. (Republic of Congo), P. flavifacies sp. n. (Tanzania), P. heteroneura sp. n. (South Africa), P. paraustralis sp. n. (South Africa), and P. sinelineata sp. n. (South Africa) are described. The morphological variety among the Afrotropical species of Paralimosina seems to be the widest. Therefore, it is expected that many other new species will be described from the region in the future. An identification key to the new taxa is provided.


The genus Paralimosina L. Papp, 1973, includes a number of sphaerocerids of the subfamily Limosininae that have robust and strongly sclerotised bodies. Genera in this subfamily have the epandrium of the male genitalia fused below the anal opening. Furthermore, important differentiating characters are located on the cercal part of the epandrial complex as well as the hypandrium, surstylus, postgonite and phallus. On the female postabdomen, the shape, armature and ratios of tergite 8 and sternite 8 can be characteristic of particular species. Likewise, the epiproct (tergite 10), cerci (not fused with tergite 10) and spermathecae may exhibit features that are diagnostic at the specific level.

Paralimosina is a diverse genus with 27 described species in the Palaearctic and Oriental regions but hitherto it has not been recorded from the Afrotropical Region (Richards 1980; Roháček et al. 2001). Hayashi (2008a) named five other species from Thailand, and Hayashi (2007, 2008b) described four new species from Malaysia.

Although I found six new species during the course of this study, it is highly likely that more new species of Paralimosina will be discovered in the future, since the morphological variety among the Afrotropical species of Paralimosina seems to be the widest.


This paper is based on studies of many double-mounted specimens of Paralimosina which are housed in the Hungarian Natural History Museum (HNHM; Budapest), National Museum (BMSA; Bloemfontein, South Africa), and KwaZulu-Natal Museum (NMSA; Pietermaritzburg, South Africa).

Abdomina of up to several (at least one) specimens of each species were removed and treated with 10% hot sodium hydroxide (NaOH) for several minutes and lactic acid, then rinsed, etc., in the standard way. Those abdomina with genitalia are now kept in glycerol in plastic microvials under the respective pinned specimens.

In the species accounts below, geographical names on specimen labels are given in their present-day spelling, whereas my annotations concerning label data are in square brackets.
