“…1, Table 2, node 3), so we propose its revalidation. Coscarón et al (2004) divided S. (Hearlea) into the species-groups Carolinae and Juarezi. We included two species of Carolinae and three of Juarezi in our analysis and, despite the low number of representatives, both groups were recovered, each defined by three synapomorphies and highly supported (Fig.…”

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.

“…ZOOTAXA male and immature stages is known. Simulium falculatum shares the female diagnostic characters of species within the subgenus Hearlea Vargas, Martínez Palacios & Díaz Nájera, as reviewed by Coscarón et al (2004). It appears close to Simulium ayrozai Vargas in scutal pattern and cibarial morphology, the two species being readily distinguished by the structure of the paraproct.…”

In this paper we clarify the status of some poorly known blackfly species from the Neotropical Region. Information is provided about their depositories, their condition, and already-established synonyms. Fifteen new synonyms are established, two species are assigned to a different subgenus, and five lectotypes are designated based on an examination of type material. The following new synonyms are proposed: Simulium tarsatum Macquart (= S. mexicanum Bellardi, S. seriatum Knab, S. aureopunctatum Malloch, S. placidum Knab, S. lugubre Lutz & Nuñez Továr, S. turgidum Hoffmann, Trichodagmia laticalx Enderlein, T. latidigitus Enderlein, S. bellardii Py-Daniel & Moreira Sampaio); S. nigrimanum Macquart (= T. spadicidorsum Enderlein); and S. townsendi Malloch (= S. chalcocoma Knab, T. ecuadoriensis Enderlein, T. latitarsis Enderlein, T. strigata Enderlein, S. muiscorum Bueno, Moncada & Muñoz de Hoyos). Five lectotypes are designated for the following species names: T. laticalx, T. latidigitus, T. spadicidorsum, T. ecuadoriensis and T. latitarsis. Two species, S. tarsale Williston & S. tarsatum Macquart, previously unplaced in the genus Simulium s.l. are now assigned to the subgenus Hemicnetha Enderlein.

A study of the monophyly and phylogenetic relationships among the Gigantodax species-groups was conducted using all Gigantodax species and six outgroups. This analysis was conducted using 71 characters, 58 of them morphological characters derived from 66 species, and 13 of them cytological characters from 11 species. We conducted two analyses under linear parsimony and implied weights. To define the best concavity value we used the frequency index. The value that recovered the most of the groups was linear parsimony search. We obtained 2037 equally parsimonious trees of 277 steps (CI=0.37 RI=0.65). The second value to recover most of the groups was implied weight search with the concavity value of one. Only the igniculus and minor groups were recovered by both analyses (linear parsimony and implied weights K=1). Under linear parsimony the phylogenetic analysis recovered two species groups (igniculus and cormonsi). The remaining four groups (“brophyi”, “cilicinus”, “minor”, and “wrighti”) are non-monophyletic. Based on the cladogram we suggest the following species groups: igniculus (igniculus group), cormonsi (cormonsi group), minor (containing “minor” + “multifilis”), brophyi (G. antarcticus, G. brophyi, G. femineus, G. rufidulus, and G. trifidus), shannoni (containing G. bettyae, G. incomitatus, G. mariobordai, G. pennipunctus, G. septenarius, and G. shannoni), and rufescens (containing G. aquamarensis, G. arrarteorum, G. basinflatus, G. cervicornis, G. cilicinus, G. clandestinus, G. corniculatus, G. cypellus, G. dryadicaudicis, G. herreri, G. horcotiani, G. impossibilis, G. incapucara, G. nasutus, G. rufescens, and G. wrighti). Some species, previously assigned to “cilicinus”, “wrighti”, and “brophyi” groups are kept as inquerandae.
