Item Implications of the tympanal hearing organ and ultrastructure of chaetotaxy for the higher classification of Embioptera. (American Museum novitates, no. 3933)(American Museum of Natural History., 2019-07-30) Szumik, Claudia.; Juárez, María Laura, 1980-; Ramírez, Martín J.; Goloboff, Pablo A.; Pereyra, Verónica V.Several slowly evolving characters are evaluated with the main objective of reinforcing the higher classification of Embioptera. An embiopteran femoral auditory organ, described here for the first time, exhibits differences in shape and position that provide diagnostic criteria for higher taxonomic groups in the order. New characters on silk ejectors, bladders, and various types of leg setae are also discussed within a taxonomic framework. The utility of these new traits and their different conditions, for identifying monophyletic groups, was tested by a preliminary phylogenetic analysis.Item New spiders of the mygalomorph genus Neocteniza (Araneae, Idiopidae).

American Museum novitates ; no. 3056(New York, N.Y. : American Museum of Natural History, 1993) Goloboff, Pablo A.Item A review of the Chilean spiders of the superfamily Migoidea (Araneae, Mygalomorphae). American Museum novitates ; no. 2888(New York, N.Y. : American Museum of Natural History, 1987) Goloboff, Pablo A.; Platnick, Norman I."The spider superfamily Migoidea is represented by four species and genera. Three belong to the family Migidae: Migas vellardi Zapfe (the female of which is described for the first time, and which remains of uncertain placement within the subfamily Miginae), the new genus and species Mallecomigas schlingeri (assigned, for the time being, to the probably paraphyletic subfamily Calathotarsinae, although it may prove to represent the sister group of all other migids), and Calathotarsus coronatus Simon (the male of which is described for the first time). The fourth species belongs to the family Actinopodidae and the new genus Plesiolena, based on Missulena bonneti (Zapfe), the female of which is described for the first time; Plesiolena is hypothesized to be more closely related to the Australian genus Missulena than to the tropical American genus Actinopus"--P. [1].Item A revision of the genus Hermacha Simon, 1889 (Mygalomorphae: Entypesidae), in southern Africa with revalidation of Hermachola Hewitt, 1915, and Brachytheliscus Pocock, 1902. (American Museum novitates, no. 3977)(American Museum of Natural History., 2021-09-02) Ríos-Tamayo, Duniesky; Engelbrecht, Ian; Goloboff, Pablo A.The southern African species of the mygalomorph spider genus Hermacha Simon, 1889, are revised. Eight species are redescribed: H. brevicauda Purcell, 1903; H. caudata Simon, 1889; H. evanescens Purcell, 1903; H. fulva Tucker, 1917; H. lanata Purcell, 1902; H. nigrispinosa Tucker, 1917; H. sericea Purcell, 1902; and H. tuckeri Raven, 1985. The female of H. sericea and the male of H. evanescens are described for the first time. Three new species are described: H. septemtrionalis, sp. nov., H. maraisae, sp. nov., and H. montana, sp. nov. On the basis of their genital morphology H. curvipes Purcell, 1902, and H. nigra Tucker, 1917, are considered incertae sedis. Pionothele capensis Zonstein, 2016, was found to be conspecific with H. brevicauda and is synonymized. The genera Brachytheliscus Pocock, 1902, and Hermachola Hewitt, 1915, are revalidated and redescribed. Hermacha capensis (Ausserer, 1871) and H. crudeni Hewitt, 1913, are transferred to Hermachola. Hermachola crudeni (Hewitt, 1913), originally described from a female, and Hermachola grahami Hewitt, 1915, originally described from a male, were found to be conspecific and synonymized. A new species, Hermachola lyleae, sp. nov., is also described. New morphological characters for the diagnoses of these genera and a dichotomous key for all species considered here are provided. Known distributions are mapped and, where available, ecological data are included. With the exception of H. caudata and H. mazoena Hewitt, 1915, all species are endemic to South Africa, but further survey work in neighboring countries is needed. This work substantially improves the taxonomy of this group of spiders and provides a foundation for further investigation of the diversity and relationships of species within the region.Item A revision of the South American spiders of the family Nemesiidae (Araneae, Mygalomorphae). Part 1, Species from Peru, Chile, Argentina, and Uruguay. Bulletin of the AMNH ; no. 224([New York] : American Museum of Natural History, 1995) Goloboff, Pablo A."The 58 species of Nemesiidae occurring in Peru, Chile, Argentina, and Uruguay are described, keyed, illustrated, and diagnosed. Of those 58 species, 39 are new. Acanthogonatus comprises 27 species; Acanthogonatus segne (Simon) is synonymized with A. franki Karsch; A. guttulata (Simon) is synonymized with A. subcalpeianus (Nicolet); Thalerommata venosa Mello-Leitão is synonymized with A. pissii (Simon); A. notatus (Mello-Leitão) is removed from the synonymy of A. patagonicus (Simon); the female previously identified as A. subcalpeianus was misidentified and belongs to a new species, A. confusus; Bolostromus incursus (Chamberlin) is transferred from the Cyrtaucheniidae to Acanthogonatus; 17 new species of Acanthogonatus are described: A. tolhuaca, A. mulchen, A. chilechico, A. quilocura, A. huaquen, A. juncal, A. alegre, A. nahuelbuta, A. hualpen, A. patagallina, A. vilches, A. recinto, A. peniasco, and A. confusus, from Chile, and A. centralis, A. parana, and A. birabeni, from Argentina; the males of A. franki, A. patagonicus, and A. subcalpeianus, and the female of A. notatus are described for first time. Lycinus Thorell (with eight species) is removed from the synonymy of Mygaloides Nicolet, as Mygaloides is an unidentifiable mygalomorph (perhaps a theraphosid); Lycinus epipiptus (Zapfe) is removed from the synonymy of L. gajardoi (Mello-Leitão); five new species of Lycinus, L. quilicura, L. domeyko, L. frayjorge, L. caldera, and L. tofo are described (all from Chile); L. longipes Thorell does not occur in Chile, previous records actually corresponding to specimens of L. caldera and L. epipiptus; the females of L. gajardoi and L. longipes are described for the first time (previously described female of L. gajardoi is actually that of L. epipiptus). Diplothelopsis Tullgren comprises two species, D. bonariensis Mello-Leitão and D. ornata Tullgren; the placement of D. hastata Mello-Leitão in this genus is almost certainly erroneous, and the genus is exclusively Argentinian. A new genus from Chile is described, Chilelopsis, which contains three new species: C. calderoni (the type species), C. serena, and C. puertoviejo. Chilelopsis is hypothesized to be the sister group of Lycinus + Diplothelopsis. A new genus, Flamencopsis, contains only the type species, F. minima (Chile). Chaco Tullgren comprises seven species; six new species are described: C. tucumana, C. sanjuanina, C. tecka, and C. patagonica from Argentina, and C. tigre and C. socos from Chile; the male of C. obscura is described for first time; Hermacha leporina Simon, from Brazil, said by Raven to belong to Chaco, is transferred to Stenoterommata, and Neostothis Vellard (from Brazil) is removed from the synonymy of Chaco; as relimited, Chaco is restricted to Chile and Argentina. Stenoterommata is represented by seven species (other species occur in Brazil); Stenoterommata argentinensis (Schiapelli and Gerschman) and Brachythele argentina Simon are synonymized with S. platense Holmberg; six new species are described: S. iguazu, S. tenuistylum, S. quena, and S. uruguai, from Argentina, S. crassistylum from Argentina and Uruguay, and S. palmar from Argentina and Brazil. Rachias is represented by only one (new) species, R. timbo. Petropolisia Mello-Leitão is removed from the synonymy of Pselligmus and placed in the synonymy of Rachias. The genus Pycnothele is represented by two species; P. modesta (Schiapelli and Gerschman) is removed from the synonymy of the Brazilian P. singularis Mello-Leitão; the females of P. modesta and P. auronitens (Keyserling) are described for first time. Pselligmus conspersus (Walckenaer) is transferred to Rachias. Xenonemesia Goloboff and Spelocteniza Gertsch are transferred to the Microstigmatidae. Neodiplothele Mello-Leitão is transferred to the Sasoninae (Barychelidae). Brachythele keithi Chamberlin is transferred to the genus Linothele (Dipluridae). A cladistic analysis of nemesiid relationships is provided, based on a matrix including all known species of Acanthogonatus, Chaco, and Diplothelopsini, as well as representatives of most nominal Neotropical nemesiid genera, and several non-Neotropical nemesiids and non-nemesiid bipectinates. The 84 terminals in the matrix were scored for 104 characters. The results of the analysis suggest that Nemesiidae as currently delimited is a paraphyletic group but they do not allow a redelimitation at the familial level; the subfamilies Pycnothelinae and Anaminae as delimited by Raven do not appear as monophyletic"--P. 4.Item Supplemental Material for 'Pennaraptoran theropod dinosaurs : past progress and new frontiers.

(Bulletin of the American Museum of Natural History, no. 440)'Item Taxonomic revision and morphology of the trapdoor spider genus Actinopus (Mygalomorphae, Actinopodidae) in Argentina. (Bulletin of the American Museum of Natural History, no. 419)(American Museum of Natural History., 2018-03-20) Ríos-Tamayo, Duniesky.; Goloboff, Pablo A.The genus Actinopus Perty, 1833, is revised for Argentina, comprising a total of 23 species. The female of A. insignis (Holmberg, 1881) is described for the first time; the species is found in northern Buenos Aires, southern Santa Fe, and Uruguay. The female of A. longipalpis (Koch, 1842), previously known only from the male type from Uruguay, is described for the first time, and the species is newly cited for Argentina (Entre Ríos). Twenty new species are recognized, described and illustrated. Thirteen of the new species are based on males and females (A. reycali, sp. nov., from Jujuy and Salta; A. clavero, sp. nov., from Córdoba; A. szumikae, sp. nov., from Córdoba, southern Buenos Aires, Santa Fe and Corrientes; A. coylei, sp. nov., from Salta and Santiago del Estero, A. argenteus, sp. nov., from Santiago del Estero, Córdoba and Catamarca, A. ramirezi, sp. nov., from Misiones, A. patagonia, sp. nov., from Chubut, La Pampa, Río Negro and southern Buenos Aires, A. gerschiapelliarum, sp. nov., from Córdoba, northern Buenos Aires, southern Santa Fe, northern La Pampa and Canelones in Uruguay, A. pampa, sp. nov., from La Pampa, A. septemtrionalis, sp. nov., from Salta, Tucumán, Catamarca, and Formosa, A. taragui, sp. nov., from Corrientes, Chaco, and Misiones, A. excavatus, sp. nov., from Córdoba, A. casuhati, sp. nov., from southern Buenos Aires). Only one of the new species described is based on females only (A. indiamuerta, sp. nov., from Tucumán); and the remaining six on males (A. puelche, sp. nov., from southern Buenos Aires and Uruguay, A. cordobensis, sp. nov., from San Luis and Córdoba, A. magnus, sp. nov., from Córdoba, A. ariasi, sp. nov., from Formosa, A. palmar, sp. nov., from Entre Ríos, and A. balcarce, sp. nov., from southern Buenos Aires). New morphological characters that can help solve phylogenetic relationships within the genus are described. A dichotomous key for all the species from Argentina is provided, as well as maps of the known geographic distribution for all the species. Three of the species treated here (A. gerschiapelliarum, A. puelche, and A. insignis) are recorded also for Uruguay.
