03EC1C29FFE4FF8EFF7AF9BC6CE9FA75.taxon	diagnosis	Diagnosis: Males of most species (except A. giganteus gen. nov. sp. nov.) resemble Parvicarina Galleti-Lima, Hamilton, Borges & Guadanucci by having the male palpal bulb embolus without accessory prolateral keels and with PI, PS, R (most species) (Figs 63 – 65) and A weakly developed. From Parvicarina, they can be distinguished by having a straight or slightly curved metatarsus I and the PI without denticles. Males of A. giganteus gen. nov. sp. nov. resemble those of Lasiodora Koch, Lasiocyano Galleti-Lima, Hamilton, Borges & Guadanucci, Vitalius Lucas, Silva Junior & Bertani, Pterinopelma Pocock, Tekoapora Galleti-Lima, Hamilton, Borges & Guadanucci, and Crypsidromus Ausserer by having the palpal bulb with a SA keel (Figs 48 – 50). They differ from the first by the absence of stridulating setae, from the other genera above by the tibia of leg IV slightly incrassate (Fig. 59), and presence of a shield of spiniform setae on retrolateral coxa III, as well as spiniform setae on basal prolateral coxae II, III, and IV. Females, except those of A. maculatus gen. nov. sp. nov., resemble those of Cotztetlana Mendoza by the presence of incrassate tibia and metatarsus IV covered both with stiff setae (Fig. 60). From Cotztetlana, they can be distinguished by the spiniform setae mainly on prolateral and retrolateral coxae II – IV (Fig. 58). Arboriticus maculatus gen. nov. sp. nov. female resembles those of Nhandu Lucas and some Vitalius species by lacking stridulatory setae on the coxae in conjunction with short spermathecae with stalks as wide as spermathecae bulbs and the area between them very sclerotized (Fig. 71). They can be distinguished by the general light brown color with pinkish setae on legs and abdomen, in addition to the presence of black dots on leg and palp segments (Fig. 79).	en	Borges, Leandro Malta, Abegg, Arthur Diesel, Paladini, Andressa, Bertani, Rogério (2025): A new genus and five new species of arboreal tarantulas (Araneae: Theraphosidae) from Brazil.

03EC1C29FFE4FF8EFF7AF9BC6CE9FA75.taxon	etymology	Etymology. The generic name is a composition of the Latin word arbor (= tree) and the suffix “ ticus ” (= belonging to) meaning ‘ which belongs to trees ”, due to arboreal habits of its species. The gender is masculine.	en	Borges, Leandro Malta, Abegg, Arthur Diesel, Paladini, Andressa, Bertani, Rogério (2025): A new genus and five new species of arboreal tarantulas (Araneae: Theraphosidae) from Brazil.

03EC1C29FFE2FF82FF7AFA4E6A8AFDD1.taxon	diagnosis	Diagnosis. Males resemble those of A. maculatus gen. nov. sp. nov. by the reduced male palpal bulb keels (Figs 4 – 6) in conjunction with the metatarsus I touching the apex of the retrolateral process when flexed. They can be distinguished from those of A. maculatus gen. nov. sp. nov. by the very reduced bulb keels PS, PI, A, lacking the R keel (Figs 4 – 6) and the longer than wide sternum (Fig. 3). Females resemble those of A. spinosissimus gen. nov. comb. nov., A. giganteus gen. nov. sp. nov., and A. tarsicrassus gen. nov. comb. nov. by the incrassate metatarsus IV with stiff setae (Fig. 76). They can be distinguished from those of A. giganteus gen. nov. sp. nov. and A. tarsicrassus gen. nov. comb. nov. by having the spermathecae stalk width equal to the not sub-spherical bulb (Fig. 12). From A. spinosissimus gen. nov. comb. nov., they can be distinguished by the retrolateral ventral area of maxillae lacking spiniform setae.	en	Borges, Leandro Malta, Abegg, Arthur Diesel, Paladini, Andressa, Bertani, Rogério (2025): A new genus and five new species of arboreal tarantulas (Araneae: Theraphosidae) from Brazil.

03EC1C29FFEEFF80FF7AFD2B68A2FCF9.taxon	discussion	Remarks. Mello-Leitão (1923) described Eupalaestrus spinosissimus in detail based on a female from Pinheiro (now Pinheiral) in the state of Rio de Janeiro, Brazil, and emphasized the most characteristic features: “ The posterior legs are thicker than the anterior legs ”, “ the tibia is thicker than the femur ”, “ the metatarsus is slightly curved and convex at the base ”, “ the posterior tibia and metatarsus are covered almost entirely with hirsute and stiff setae ”, “ the coxae of the first pair of legs have transverse rows of small black spines pointing forward ”, “ there are some spines on the distal end of the posterior face of the maxilla ”, and “ there are numerous black spines in dense areas on the anterior face of the posterior coxae and on the posterior faces of the second and third coxae ”. This last character gives the species name, spinosissimus (Mello-Leitão 1923). In the same publication, Mello-Leitão (1923) described P. holophaeus, also based on a female specimen from Piracicaba, state of São Paulo, Brazil. However, the author did not mention the remarkable features observed and detailed in the description of E. spinosissimus. Pérez-Miles (1992) later considered the type specimen of E. spinosissimus as lost, and considered the species as incertae sedis. Some years after, Bertani (2001) revalidated E. spinosissimus based on the analysis of other specimens having those unusual features. After examination of the supposed holotype of P. holophaeus, Bertani (2001) considered it as a junior synonym of E. spinosissimus, since it has most of the features mentioned by Mello-Leitão (1923) in that species. Upon reexamining the type assigned to P. holophaeus, we confirm that all the features mentioned by Mello-Leitão for E. spinosissimus are present in this specimen. Particularly noteworthy are the spiniform setae at the distal end of the maxilla, which were observed only in this specimen (Fig. 16). It is astonishing that the same remarkable morphological features highlighted by Mello-Leitão (1923) for E. spinosissimus are not mentioned in the description P. holophaeus even though the putative holotype bears them, which lead us to suspect it might not be the real type. Inconsistencies in the descriptions, specimen details, and current findings lead us to conclude that the specimen MZUSP 130 corresponds to the previously presumed lost type specimen of E. spinosissimus. However, Mello-Leitão (1923) declared that the type of E. spinosissimus was deposited in “ his own collection ” which was later included in the MNRJ arachnological collection. Nevertheless, Silva-Moreira et al. (2010) stressed the difficulties in stablishing the actual collection, where the types of Mello-Leitão were deposited, and that there is a historical confusion as to whether some mygalomorph types were deposited at the MZUSP or MNRJ. Furthermore, Mello-Leitão (1923) stated in the description that the number of the holotype of Pamphobeteus holophaeus is MZUSP 129 - A, whereas the specimen labeled as type has the number MZUSP 130, indicating that this is not the real type of P. holophaeus, which seems to be lost (Fig. 15). Additionally, the type locality of Pamphobeteus holophaeus is Piracicaba, in the state of São Paulo, Brazil, which has very distinct phytophysiognomy and topography when compared to the mountainous areas where the species of Arboriticus gen. nov. are known to occur (Fig. 1). Pamphobeteus holophaeus was described and keyed by Mello-Leitão together with other Pamphobeteus (now Vitalius) species he described, and the type locality of this species is an area where the species Vitalius dubius (Mello-Leitão, 1923) is very common (Bertani 2001), and we have little doubt that they are conspecific. Therefore, we remove Pamphobeteus holophaeus Mello-Leitão, 1923 from the synonymy with Eupalaestrus spinosissimus Mello-Leitão, 1923, transfer it to Vitalius holophaeus (Mello-Leitão, 1923) comb. nov., and consider it a junior synonym of Vitalius dubius (Mello-Leitão, 1923) n. syn.	en	Borges, Leandro Malta, Abegg, Arthur Diesel, Paladini, Andressa, Bertani, Rogério (2025): A new genus and five new species of arboreal tarantulas (Araneae: Theraphosidae) from Brazil.

Males resemble those of A. minor gen. nov. sp. nov. and A. petropolis gen. nov. sp. nov. by the reduced male palpal bulb keels (Figs 21 – 23) in conjunction with the metatarsus I touching the retrolateral process of the tibial spur laterally when flexed. They can be distinguished from those of A. minor gen. nov. sp. nov. by the PP of tibial spur not being thickened and the RP longer than the PP (Figs 24 – 26). From A. petropolis gen. nov. sp. nov., they can be distinguished by the tegulum not elongated and embolus narrowing abruptly from the tegulum (Figs 21 – 23). Females resemble those of A. spinosissimus gen. nov. comb. nov., A. giganteus gen. nov. sp. nov., and A. celsoi gen. nov. sp. nov. by the incrassate metatarsus IV with stiff setae (Fig. 29). They can be distinguished from those of A. spinosissimus gen. nov. comb. nov. and A. celsoi gen. nov. sp. nov. by the spermathecae stalk width narrower than the sub-spherical bulb (Fig. 28). From A. giganteus gen. nov. sp. nov. they can be distinguished by the small size and slightly incrassate tibia and metatarsus IV (Fig. 29).	en	Borges, Leandro Malta, Abegg, Arthur Diesel, Paladini, Andressa, Bertani, Rogério (2025): A new genus and five new species of arboreal tarantulas (Araneae: Theraphosidae) from Brazil.

03EC1C29FFF3FF91FF7AFF32685AFF15.taxon	diagnosis	Diagnosis. Males resemble those of A. celsoi gen. nov. sp. nov. by the reduced male palpal bulb keels (Figs 63 – 65) in conjunction with the metatarsus I touching the apex of the retrolateral process when flexed. They can be distinguished from those of A. celsoi gen. nov. sp. nov. by the male palpal bulb keels PS, PI and A slightly reduced, but easy to see, presence of R keel (Figs 63 – 65), and rounded sternum (Fig. 62). Females can be distinguished from those of all other species by the non incrassate metatarsus IV lacking stiff setae and the two spermathecae fused by a short sclerotized area (Fig. 71).	en	Borges, Leandro Malta, Abegg, Arthur Diesel, Paladini, Andressa, Bertani, Rogério (2025): A new genus and five new species of arboreal tarantulas (Araneae: Theraphosidae) from Brazil.
