The new Ischnocolinae genus Catumiri is described. The species Cenobiopelma argentinense
(Mello-Leitão, 1934), considered a junior synonym of Oligoxystre Vellard, 1924, is transferred to
the present genus. Three new species are also described: C. chicaoi n. sp., from south of Bahia,
Una; C. petropolium n. sp., from Petrópolis, Rio de Janeiro (type...

... The origin of Rhytidicolidae NEW RANK dates back to the late Cretaceous ~ 70 Mya but its diversification, according to our sample, occured in the Cenozoic during the Neogene and Quaternary periods. Likewise, the Theraphosidae clade in our dated topology split ~ 75 Mya during the Cretaceous between the Ischnocolinae (including the South American genus Catumiri Guadanucci, 2004) and the other lineages. ...
The family Nemesiidae was once among the most species-rich of mygalomorph spider families. However, over the past few decades both morphological and molecular studies focusing on mygalomorph phylogeny have recovered the group as paraphyletic. Hence, the systematics of the family Nemesiidae has more recently been controversial, with numerous changes at the family-group level and the recognition of the supra-familial clade Nemesioidina. Indeed, in a recent study by Opatova and collaborators, six nemesiid genera were transferred to the newly re-established family Pycnothelidae. Despite these changes, 12 South American nemesiid genera remained unplaced, and classified as incertae sedis due to shortcomings in taxon sampling. Accordingly, we evaluate the phylogenetic relationships of South American nemesioid species and genera with the principle aim of resolving their family level placement. Our work represents the most exhaustive phylogenomic sampling for South American Nemesiidae by including nine of the 12 genera described for the continent. Phylogenetic relationships were reconstructed using 457 loci obtained using the spider Anchored Hybrid Enrichment probe set. Based on these results Nemesiidae, Pycnothelidae, Microstigmatidae and Cyrtaucheniidae are not considered monophyletic. Our study also indicates that the lineage including the genus Fufius requires elevation to the family level (Rhytidicolidae Simon, 1903 (NEW RANK)). In Pycnothelidae, we recognize/delimit five subfamilies (Diplothelopsinae, Pionothelinae NEW SUBFAMILY, Prorachiinae NEW SUBFAMILY, Pselligminae NEW RANK, Pycnothelinae). We also transfer all the 12 South American nemesiid genera to Pycnothelidae: Chaco, Chilelopsis, Diplothelopsis, Flamencopsis, Hermachura, Longistylus, Lycinus, Neostothis, Prorachias, Psalistopoides, Pselligmus, Rachias. Additionally, we transferred the microstigmatid genus Xenonemesia to Pycnothelidae, and we propose the following generic synonymies and species transfers: Neostothis and Bayana are junior synonyms of Pycnothele (NEW SYNONYMY), as P. gigas and P. labordai, respectively (NEW COMBINATIONS); Hermachura is a junior synonym of Stenoterommata (NEW SYNONYMY), as S. luederwaldti (NEW COMBINATION); Flamencopsis is a junior synonym of Chilelopsis (NEW SYNONYMY), as C. minima (NEW COMBINATION); and Diplothelopsis is a junior synonym of Lycinus (NEW SYNONYMY), as L. ornatus and L. bonariensis (NEW COMBINATIONS). Considering the transferred genera and synonymies, Pycnothelidae now includes 15 described genera and 137 species. Finally, these results provide a robust phylogenetic framework that includes enhanced taxonomic sampling, for further resolving the biogeography and evolutionary time scale for the family Pycnothelidae.

... Esta misma condición ha sido observada en las familias de arañas Theraphosidae y Nemesiidae, las cuales presentan géneros con especies que tienen mucha variación en la genitalia de las hembras mientras que la genitalia masculina está muy preservada (Bertani, 2001;Yamamoto et al., 2007;Indicatti et al., 2008aIndicatti et al., , 2008b. Por otra parte Guadanucci (2004) reportó para el género Catumiri Guadanucci, 2004 que las espermatecas de C. parvum (Keyserling, 1878) y C. argentinense (Mello-Leitão, 1941) son muy similares una con otra, y no existen caracteres morfológicos para distinguir las hembras de ambas especies. La diferenciación entre estas especies se basa en la variación encontrada en los bulbos copuladores de los machos y por su distribución geográfica. ...
Intraspecific variation in males of Actinopus sp. (Mygalomorphae: Actinopodidae)
of northern Argentina”. Little is known about the diversity and morphology of the
neotropical genus Actinopus Perty, 1833. On this work the focus is given to the intra-specific
variations of somatic (cephalothorax and sternum) and genital (bulbs) characters in a sample
of males of Actinopus sp. Geometric morphometric techniques were applied in order to
quantify the shape change. The analysis of a subsample showed low levels of variation in both
groups of characters. The results suggest a high level of conservatism of the genital and
somatic characters on these males.
... This large geographical barrier between the Hapalotremus species from the Andes and the Atlantic Forest, together with the advance during recent years in the study of the taxonomy of many theraphosid species from Brazil (Indicatti et al. 2008;Guadanucci 2011;Bertani 2012) led us to question the taxonomic status of the Brazilian Hapalotremus species. Moreover, the synonymies proposed by Raven (1985) involving Cyclothoracoides, Dolichothele and Goniodontium were made mainly considering only the reduced number of cuspules on the labium and maxillae, a widespread character between many theraphosid species (Guadanucci 2004(Guadanucci , 2007Indicatti et al. 2008;Guadanucci and Silva 2012;Guadanucci and Wendt 2014). Finally, a comprehensive cladistic analysis including all species of Hapalotremus is still needed to shed light on the status of the genus. ...
A new species of Hapalotremus Simon, 1903 from northern Argentina is described and illustrated. Hapalotremus martinorum sp. nov. differs from all other congeners by the colour pattern of live specimens. Males differ in the male palpal bulb morphology, with thickened and less curved embolus having a blunt subapical keel and less-developed apical keel. Females differ in the shape of the spermathecae, with the lateral bases more pronounced than the superiors and the upper edge more rounded. Specimens were captured inhabiting short burrows or crevices under stones in high cloud forests. Hapalotremus cyclothorax (Mello-Leitão 1923) is a junior synonym of Homoeomma montanum (Mello-Leitão, 1923), Hapalotremus scintillans (Mello-Leitão 1929) is a junior synonym of Pachistopelma rufonigrum Pocock, 1901, Hapalotremus exilis (Mello-Leitão 1923) and Hapalotremus muticus (Mello-Leitão 1923) are considered species inquirenda.
... Some of the genera hitherto included in 'Ischnocolinae' have been revised or recently described, providing updated diagnoses and descriptions, namely Catumiri (see original description in Guadanucci 2004), Oligoxystre (see revision in Guadanucci 2007), Nesiergus (see revision in Guadanucci & Gallon 2008), Chaetopelma (see revision in Guadanucci & Gallon 2008), Ischnocolus (see revision Guadanucci & Wendt 2014), Sickius (monotypic -S. longibulbisee genus revalidation in Bertani & Silva 2002), Guyruita (see original description in Guadanucci et al. 2007) and Plesiophrictus (see taxonomic notes in Guadanucci 2011b). ...
The mygalomorph spider subfamily ‘Ischnocolinae’ was originally established as a group based on the presence of divided tarsal scopula. Later, the divided condition of the scopula was considered the plesiomorphic state, which could not support the monophyly of ‘Ischnocolinae’. In Raven 1985, the subfamily was considered paraphyletic, pending a phylogenetic analysis to reinvestigate monophyletic groups. This study comprises such a phylogenetic analysis, based on morphological data, that includes representatives of all genera currently included in ‘Ischnocolinae’ as well as representatives of all other nine Theraphosidae subfamilies (Thrigmopoeinae, Ornithoctoninae, Eumenophorinae, Stromatopelminae, Harpactirinae, Selenogyrinae, Theraphosinae, Aviculariinae and Selenocosmiinae). The family Theraphosidae is considered monophyletic and expanded to include three additional genera previously considered as possible Barychelidae, namely Brachionopus (as Harpactirinae), Trichopelma and Reichlingia (as Ischnocolinae sensu stricto) while ‘Ischnocolinae’ as previously defined does not appear as monophyletic. However, two monophyletic groups were defined as subfamilies to include some former ‘Ischnocolinae’ representatives. The first group includes Acanthopelma rufescens, Trichopelma nitidum, Reichlingia annae, Ischnocolus spp., Holothele rondoni, Holothele culebrae and Holothele aff culebrae and is hereby named as Ischnocolinae (sensu stricto). The other subgroup comprises Sickius longibulbi, Holothele incei, Holothele aff incei, Guyruita spp., Schismatothele lineata, Hemiercus modestus, Holothele colonica and Holothele sp., together established as Schismatothelinae subfam. nov. Several genera included in former ‘Ischnocolinae’ appear as monophyletic (Catumiri, Oligoxystre, Heterothele, Nesiergus, Chaetopelma, Ischnocolus, Guyruita and Plesiophrictus). However, the genera Holothele, Schismatothele and Hemiercus deserve more attention in order to evaluate their intrarelationships and inclusion of species.
... The only reported genus of American theraphosids that produces fixed egg-sacs is Oligoxystre Vellard, 1924, an Ischnocolinae (Gallon & Gabriel, 2006). Costa & Pérez-Miles (2002) reported that Olygoxystre argentinense laid fixed egg-sacs, but this species was transferred to the genus Catumiri by Guadanucci (2004) and considered as a misidentification by Fukushima et al. (2011). This created the new combination Catumiri parvum (Keyserling, 1878) and thus Catumiri is the second known New World Ischnocolinae genus with fixed egg-sacs. ...
The theraphosine genus Hemirrhagus Simon 1903 is revised based on the examination of the type specimens and additional material collected in Mexico. Eight species were redescribed and illustrated. The males of Hemirrhagus ocellatus, Hemirrhagus papalotl, and Hemirrhagus stygius, formerly unknown, are described for the first time. Five new species were recognized and are newly described and illustrated. Hence, Hemirrhagus comprises 21 valid species, all endemic to Mexico. All species are keyed and mapped. New taxonomic features are included in the descriptions and different types of stridulatory organs are described for the first time for the genus. It is reported for the first time that Hemirrhagus is the only known Theraphosinae that lays fixed egg-sacs. Hemirrhagus embolulatus sp. nov. is described as the only known Hemirrhagus that possesses embolus keels present in other Theraphosinae genera.

... .) belonging to the families Actinopodidae, Dipluridae, Idiopidae, Migidae, Mecicobothriidae, Microstigmatidae, Nemesiidae and Theraphosidae, distributed in Argentina, Uruguay and southern Brazil. Data included in the analysis were obtained by examination of two museum collections (MACN: Museo Argentino de Ciencias Naturales Bernardino Rivadavia, Buenos Aires, Argentina; FCIEN: Facultad de Ciencias, Universidad de la República, Montevideo, Uruguay) and from the arachnological literature (Schiapelli & Gerschman de Pikelin, 1945, 1967, 1970, 1966, 1971, 1978 Gerstch & Platnick, 1979; Goloboff, 1987 Goloboff, , 1995 Goloboff & Platnick, 1992; Bertani, 2001; Guadanucci, 2004; Indicatti et al., 2007 Indicatti et al., , 2008 Miglio, 2009; Bertani et al., 2011; Ferretti et al., 2011; Fukushima et al., 2011 ). The latitude and longitude of the respective localities were defined according to the following databases: Global Gazetteer (Falling Rains Genomics, www.fallingrain.com); ...
A panbiogeographical analysis of Mygalomorphae spiders was undertaken in order to determine generalized tracks and biogeographical nodes in the peripampasic orogenic arc. This arc comprises mountainous systems that harbour a high number of endemic species, while they exhibit biotic connections that have become fragmented probably during Tertiary tectonics. They are considered relevant areas for biodiversity conservation. A total of 1078 records of 51 Mygalomorphae species were analysed and ten areas were delimited based on geological data. We used track analysis and parsimony analysis of endemicity as a panbiogeographical tool. Five generalized tracks and three nodes were recovered. The tracks recovered in Argentina could be explained as a consequence of two events: (i) Atlantic marine transgressions during the Middle and Late Miocene; and (ii) changes in the climate of southern South America from the Miocene to Pliocene, caused by the gradual raising of the Andean chain and also, the additional uplift of Pampean and Subandean ranges. The southeastern Brazil and Uruguayan generalized tracks could be explained by the Rio de La Plata Craton.
... To date, the known Uruguayan theraphosid fauna comprises 18 species of the genera Acanthoscurria Ausserer 1871, Eupalaestrus Pocock 1901, Grammostola Simon 1892, Catumiri Guadanucci 2004, Homoeomma Ausserer 1871, Lasiodora C.L. Koch 1850, Plesiopelma Pocock 1901 and Avicularia Lamarck 1818 (Platnick 2010). Uruguay is a well-sampled country (Pérez-Miles et al. 1993), with many taxonomic studies on the family (Schiapelli & Gerschman de Pikelin 1964, 1970; Gerschman de Pikelin & Schiapelli 1972; Pérez-Miles 1992; Guadanucci 2004), being one of the best known theraphosid faunas in the world, even though some questions remain to be resolved. ...

One of these questions is the presumed presence of Avicularia species in Uruguay, inconsistent with the known geographic distribution of the genus, which is otherwise limited to Southeastern Brazil (Bertani & Fukushima 2009). ...
... Eurypelma parvum Roewer 1942:241. Catumiri uruguayense Guadanucci 2004:7, figs.10–15 new synonymy Oligoxystre argentinense Costa et al. 2000:131 (misidentification); Costa & Pérez-Miles 2002:571 (misidentification). ...
The taxonomic status of four species of Avicularia Lamarck 1818 described from Uruguay: Avicularia anthracina (C.L. Koch 1842), Avicularia alticeps (Keyserling 1878), Avicularia parva (Keyserling 1878) and Avicularia tigrina (Pocock 1903) is discussed. The holotypes and/or original descriptions of these species were examined, and two taxonomic synonymies are needed, which are presented herein. Avicularia anthracina is transferred to Grammostola, resulting in Grammostola anthracina (C.L. Koch 1842) new combination and is considered a senior synonym of Grammostola mollicoma Ausserer 1875 new synonymy. Likewise, Avicularia parva is transferred to Catumiri Guadanucci 2004, where it is placed in the synonymy of Catumiri uruguayense Guadanucci 2004 new synonymy. Avicularia tigrina and Avicularia alticeps, originally described in the genera Ischnocolus Ausserer 1875 and Pterinopelma Pocock 1901, respectively, are herein considered nomina dubia since their types are presumed lost.
... The labium shape, absence of labial cuspules, and small number of cuspules on the maxillae are shared in South America by only two ischnocoline genera, Oligoxystre and Catumiri. Oligoxystre is not known from Uruguay or southern Brazil, so the unique ischnocoline genus so far known in Uruguay is Catumiri Guadanucci 2004, with a single species in the country, C. uruguayense Guadanucci 2004 Redescription.-Female holotype: Total length, not including chelicerae or spinnerets 44.0 (Fig. 2). Cephalothorax 19.9 long, 21.0 wide. ...
A new species of the medically important recluse spider genus Loxosceles Heinecken & Lowe 1832 is described from the State of Bahia, Brazil. The species occurs between rocks and crevices, as well as in and around man-made structures. The new species belongs to the gaucho group, as evidenced by the spermathecal shape and color pattern. The presence of a long male palpal tibia is unusual in the gaucho group; thus, the inclusion of the new species in this group is discussed.
... The total number of samples was 72 per method and area. Spiders were identified at the species level following Raven (1985), Goloboff (1995), and Guadanucci (2004). Actinopus sp.1 constitutes the only morphospecies that could not be identified at the species level. ...
Martín García I. is located in the upper La Plata River, at the outlet of the Uruguay River, northeastern Buenos Aires Province, Argentina. Due to its status as a protected area, it is imperative to know the biological diversity that is intended to be preserved. Mygalomorph spiders have life-history characteristics that parallel general characteristics of well-studied taxa that are "extinction prone", either at the population or species level. We analyzed the abundance and distribution in space and time of mygalomorph spiders at the specific level. We also offer some comments of distributional patterns in a geological context. Spider abundances were sampled from Mar. 2004 to Nov. 2006 by hand-capture and pitfall traps in 5 different ecological areas. To determine the habitat preference of the species, we used the Kruskal-Wallis one-way ANOVA test. Species of the Mygalomorphae occurring on Martín García I., Actinopus sp. (Actinopodidae), Catumiri argentinense (Theraphosidae), Stenoterommata platensis (Nemesiidae), and Xenonemesia platensis (Microstigmatidae) were distributed among all habitats, with 1 specialist in only 1 habitat type. Xenonemesia platensis showed a restricted distribution possibly influenced by the geological history related with the Río de la Plata Craton as for S. platensis. Other distributional patterns may have been affected by more-recent transgressions and regressions of the sea through the Río de la Plata River.
