Milton Norberto Strieder¹

Abstract: ABSTRACT. The female of Thyrsopelma itaunense (d'Andretta & González, 1964) is described and illustrated for the first time. T. itaunense and T. orbitale are morphologically compared. New records on geographical distribution are aslo presented.

Simulium (Trichodagmia) Enderlein, 1934 has an unstable classification system. The broader concept of the subgenus includes five species-groups resulting from an extensive history of synonymisations, often outside of a phylogenetic framework. This concept also ignores relationship hypotheses with the Afrotropical subgenera S. (Anasolen) Enderlein, 1930, S. (Freemanellum) Crosskey, 1969, S. (Xenosimulium) Crosskey, 1969, and the Oviedoi species-group, with several Neotropical species of S. (Trichodagmia). We performed a morphological phylogenetic analysis to test the monophyly of S. (Trichodagmia), its species-groups, and their relationship with the above-mentioned subgenera and Oviedoi species-group. We analysed a data matrix with 69 terminal taxa and 62 characters under parsimony implied weights, with a range of concavities (k1–100), finding three categories of k. Our analysis concludes that S. (Trichodagmia) is not monophyletic, since Oviedoi and the Afrotropical subgenera group with its species-groups Tarsatum and Orbitale. Therefore, we propose a new classification for S. (Trichodagmia) by restricting it to the Orbitale species-group, revalidating S. (Hearlea) Vargas et al., 1946, S. (Hemicnetha) Enderlein, 1934, S. (Obuchovia) Rubtsov, 1947 and S. (Shewellomyia) Peterson, 1975, synonymysing S. (Xenosimulium) with S. (Anasolen), and erecting a new subgenus, S. (Disculter) subgen. nov. for Oviedoi. The geographical distribution of the groups involved is discussed.
