Revision of the spider genus Mystaria Simon, 1895 (Araneae : Thomisidae) and the description of a new genus from the Afrotropical region

摘要

The spider genera Mystaria Simon, 1895 and Paramystaria Lessert, 1919 arerevised (Mystarini: Thomisidae). About 400 individuals were studied. The approachfollowed was classical taxonomy using illustrated sexual dimorphic copulatory charactersand described morphological characters, photographed or measured. Paramystaria isconsidered a junior synonym of Mystaria, based on similarity to the type M. rufolimbataSimon, 1895 but with the exclusion of M. unicolor Simon, 1895, a species last studied in1895. Mystaria unicolor is re-described and placed in a new genus, Leroya gen. n.,together with L. silva sp. n. (♂♀, DRC) which is recognised as the type species. Mystarianow contains 13 well-defined species, four of which are in new generic combinations.Four males are described for the first time, and eight new species. Re-described speciesinclude M. flavoguttata Lawrence, 1952, M. lata Lawrence, 1927, M. rufolimbata and M.variabilis Lessert, 1919. Subspecies elevated to species level include M. occidentalisMillot, 1942 and new species descriptions include M. budongo sp. n. (♂, Rwanda, DRC,Uganda), M. irmatrix sp. n. (♀♂, Mozambique, South Africa) M. lindaicapensis sp. n.(♀♂, South Africa), M. mnyama sp. n. (♀♂, South Africa), M. oreadae sp. n. (♀,Rwanda, DRC), M. savannensis sp. n. (♀♂, Botswana, South Africa, Zambia,Zimbabwe), M. soleil sp. n. (♀♂, Uganda, Kenya) and M. stakesbyi sp. n. (♀♂, Ghana,DRC, Kenya, Rwanda, Tanzania, Uganda). The insufficiently known taxa Paramystariadecorata Lessert, 1919 and P. variabilis delesserti Caporiacco, 1949 are also transferredto Mystaria. Keys are provided to species and related tribal genera, with geographic distributions of species recorded. Revisions of more genera are needed, in particular ofthose genera related to Mystarini, before phylogenetic relationships can be considered.
