Description of four new Steatoda species (Araneae: Theridiidae) from the Mediterranean region with notes on some related species
Abstract
Four new Steatoda species from the Mediterranean region are diagnosed, described and illustrated: S.
koeni sp. nov. (♂♀, Morocco), S. ingeae sp. nov. (♂♀, Morocco), S. dickjonesi sp. nov. (♂♀, France)
and S. verae sp. nov. (♂♀, Spain). The holotype of S. triangulosa concolor (Caporiacco, 1933) was
examined and found to be a subadult specimen, the subspecies is elevated to species level and S.
concolor stat. nov. is described from both sexes (♂♀, Libya, Tunisia, Algeria), and the female of S.
trianguloides is redescribed. Three new synonyms are proposed: S. moerens (Thorell, 1875) is found
to be a junior synonym of S. latifasciata (Simon, 1873) new syn.; S. incomposita (Denis, 1957) is found
to be a junior synonym of Steatoda albocincta (Lucas, 1846) new syn.; S. albomaculata infuscata
(Schenkel, 1925) is synonymized with S. albomaculata (De Geer, 1778) new syn.; S. venator (Audouin,
1826) is considered a nomen dubium. All Euro-Mediterranean Steatoda species except S. xerophila
Levy & Amitai 1982 are illustrated and a key to the species is provided.
