Additional material examined. BRAZIL: Tocantins: Caseara, 9°18'15.6"S, 49°57'28.4"W: 2♂, 11.V.2016, A.B. Bonaldo et al. leg. (MPEG 35018); Pium, 09°58'38.7"S, 50°02'05.0"W: 1♂, 19.V.2016, A.B. Bonaldo et al. leg. (MPEG 35019). Revised diagnosis. A. draconicaudatus is similar to A. shenlong sp. nov. by having an elongate and stout projection on the retrolateral border of the embolic disc that extends towards the retrolateral tegulum border and bears several branches (Figs 21D, 26A, 26C, 27A); also, by having the RvTA pointing ventrally, with projections on its border (Figs 21F, 22B, 26G). However, the male of A. draconicaudatus can be distinguished by having the RvTA with a single serrated projection, and a RTA reduced to spikes (Figs 26G, 27 B–D), whereas in A. shenlong sp. nov. the RvTA has four projections (three with acute tip and one with serrated tip), and the RTA serrated tip reaches the same height of the RvTA tip along palp axis (Figs 21F, 22B, 26H). The female of A. shenlong sp. nov. is unknown, but among the currently known females of Amphidraus, A. draconicaudatus sp. nov. is most similar to those of A. draconitupan sp. nov., both with spermathecae kidney-shaped, with glands near copulatory openings and with a narrow dorsal pocket placed posteriorly on epigynal plate (Figs 24D, 25D, 27E). However, the female of A. draconicaudatus sp. nov. can be distinguished from that of A. draconitupan sp. nov. by having longer copulatory ducts connected to the inner posterior border of spermathecae (see Salgado & Ruiz 2017: fig. 24F), whereas they connect to the outer border of the spermathecae in A. draconitupan (Fig. 25D). Description. See Salgado & Ruiz (2017). Variation. Among the males examined, we observed the following variation in palpal structures (Figs 26 A–D, 26G): the superior border of the branched projection of embolic disc can be smooth (Figs 26 A–B) or occupied by large serial spikes (similar to a comb) (Figs 26 C–D). We decided to refrain from describing this variation as a new species and all these forms are considered conspecific. Also, the number and shape of branches on the RvTA is variable (Fig. 26G; see Salgado & Ruiz 2017: figs 23B, 24B, 24D). Note. Amphidraus draconicaudatus, A. shenlong sp. nov. and A. draconitupan sp. nov. clearly compose a particular group within the genus. The males in this group have one stout projection that emerges from the retrolateral border of the embolic disc and extends towards to retrolateral border of tegulum (Figs 22A, 25A, 26A, 27A). Moreover, males also have pockets on outer faces of chelicerae (Figs 28 A–C, 29A–B), of unknown use. Distribution. Known only from the state of Tocantins (Brazil) (Fig. 30).Published as part of Salgado, Alexandre & Ruiz, Gustavo R.

Barreiros leg., deposited in MPEG 29052); World Spider Catalog 2018. Additional material examined. BRAZIL: Pará: 1♂ from Floresta Estadual do Trombetas, Rio Acapu (along about 25 km on the North margin), [01°06'10.10"S, 56°26'04.00"W], Oriximiná, 10–18.X.2014, M.B. Aguiar-Neto et al. leg. (MPEG 35013). Revised diagnosis. Amphidraus caxiuanan Salgado & Ruiz, 2017 and A. manauara sp. nov. have the embolic disc with one long, prolaterally projected, distal process (dPED) with rounded tip, and one short, ventrally projected ventral process (vPED) (Figs 17A, 19C); also, the same pattern of tibial apophyses: the RvTA is short and rounded and the RTA emerges from retrodorsal portion of tibia, being curved and projected to the apex of palp (Figs 19 E–G); proximal dorso-prolateral portion of cymbium is prominent in both species, and there is a proximal retro-dorsal cavity on cymbium (Figs 17B, 19B, 19D). However, Amphidraus caxiuanan can be distinguished by having a longer proximal dorso-prolateral projection of cymbium (Figs 19B, 19D) and longer RTA (Figs 19 E–G). Moreover, the embolus shaft and the embolic filament are longer in proportion to the embolic disc in A. caxiuanan (Figs 19A, 19C). The female of A. caxiuanan is still unknown. Description. See Salgado & Ruiz (2017). Variation. Based on comparisons between the type specimen of A. caxiuanan from Melgaço, Pará, Brazil, and this new male from Oriximiná, Pará, Brazil (about 550 km from the type locality; Fig. 20), we observed several similarities, including in tibial apophyses and especially in the embolic disc, which made us refrain from describing a new species from Oriximiná. That male is herein recognized as being a variant form of A. caxiuanan. Hence, palpal variation within the species is summarized as follows (Figs 18 B–D, 18F–H, 19C–D, 19F–G): the RTA has a slight (Figs 18G, 19F) or accentuated curvature (Figs 18C, 19G); the dorso-prolateral, proximal cymbial projection varies in length (Figs 18D, 18H); RTA length is also variable (Figs 18 C–D, 18G–H, 19F–G). However, the proportions of these structures in the male from Oriximiná are intermediate when comparing the holotype of A. caxiuanan and the holotype of A. manauara (whose type locality is about 450 km away from Oriximiná; Fig. 20), which could indicate a cline across the Amazon River. Nevertheless, the embolic disc of the male palp of A. manauara is different enough to convince us to describe it as a new species (see diagnoses above). Distribution. Known only from the state of Pará, Brazil (Fig. 20). It is worth mentioning that, if the specimens from Oriximiná and Melgaço are indeed conspecific, this small species of jumping spider occurs in preserved forests on both margins of the old Amazon River, which is between two and eight kilometers wide in that portion of South America. This provides evidence for the high ability of dispersal present in this species.Published as part of Salgado, Alexandre & Ruiz, Gustavo R.

Amphidraus araripe Salgado & Ruiz 2019, sp. nov.
No full textAmphidraus araripe sp. nov. Figs 11–14 Type material. Holotype: Ƌ from Floresta Nacional do Araripe-Apodi, 7°18'39.6"S, 39°26'49.2"W, Crato, Ceará, Brazil, 06.II.2011, L.S. Carvalho et al. leg. (MPEG 35011); Paratypes: 1 Ƌ and 1♀ from Parque Nacional de Ubajara, Trilha da Samambaia, 3°50'19.4"S, 40°53'58.6"W, Ubajara, Ceará, Brazil, 14.V.2013, L.S. Carvalho et al. leg. (UFMG 14887). Etymology. The specific epithet is a noun in apposition taken from the locality of the holotype. Diagnosis. Among all species of Amphidraus, A. araripe sp. nov. is most similar to A. pulvinus Salgado & Ruiz, 2017 by having the tegulum with small retrolateral spermophore loop (RSPL) (Figs 11D, 13B; see Salgado & Ruiz 2017: fig. 8C) and the same tibial apophysis pattern: the retroventral tibial apophysis (RvTA) and intercalary tibial apophysis (ITA) are short and blade-shaped (the ITA with an internal basal projection; black arrow in Fig. 11E; see also Salgado & Ruiz 2017: fig. 8D) and the RTA is linked to an inflated membrane (Figs 11 E–G, 13B–C; see Salgado & Ruiz: figs 8B, 8D). These species also have an embolic disc with a distal process projected to prolateral side and a ventral process projected to retrolateral side (Figs 11C, 13A; see Salgado & Ruiz 2017: fig. 8C). However, A. araripe sp. nov. can be distinguished by having the RvTA and ITA more separated from each other (Figs 11F, 13B), whereas these are almost fused in A. pulvinus (see Salgado & Ruiz 2017: fig. 8D). In addition, A. araripe sp. nov. has a vPED placed near the distal processes (Figs 11C, 13A), whereas in A. pulvinus the vPED is placed on the prolateral border of embolic disc (see Salgado & Ruiz 2017: fig. 8C). The female of A. pulvinus is unknown, but among the Amphidraus species currently known, the epigyne of A. araripe sp. nov. is most similar to that of A. manaura sp. nov., both with glands near copulatory openings and with epigynal plate with border slightly bilobed (Figs 12C, 13D, 16D, 17D). However, the female of A. araripe sp. nov. differs by having a longer copulatory duct (with one loop ventrally projected) and by having the less expanded border of epigynal plate (Figs 13D, 17D).

Amphidraus cornipalpis Salgado & Ruiz 2019, sp. nov.
No full textAmphidraus cornipalpis sp. nov. Figs 1–6, 14 Type material. Holotype: Ƌ from Parque Nacional da Serra das Confusões, [09°10'31.4"S, 43°33'20.8"W], Guaribas, Piauí, Brazil, 15.XII.10, L.S. Carvalho et al. leg. (MPEG 35014). Paratypes: 1 ♀, same data as holotype [MPEG 35015]; 1♂ and 1♀ from Caruaru, [08°17'08.6"S, 35°58'06.7"W], Pernambuco, Brazil, 2009–2010, H.P. Amorim leg. [IBSP 160615 (♂), 160616 (♀)]. Etymology. The specific epithet is a compound adjective in Latin (cornus + palpus) and refers to the shape of distal process on the embolic disc (Fig. 3A). Diagnosis. Males of Amphidraus cornipalpis sp. nov. share similarities with those of Amphidraus loxodontillus Salgado & Ruiz, 2017, both with an embolic disc with one poorly-sclerotized, distal lamella that covers part of dPED ventral view (white arrows in Figs 3 A–B). However, males of A. cornipalpis sp. nov. can be distinguished from those of A. loxodontillus by having a longer and acute distal process on embolic disc (dPED) with the tip curved distally (shaped like a cow horn) (Figs 2C, 3A, 5A, 5D, 6 D–E), whereas in A. loxodontillus the dPED is short and rounded (Fig. 3B; see also Salgado & Ruiz 2017: fig. 26C). In addition, A. cornipalpis sp. nov. has a reduced RTA (as large as RvTA in A. loxodontillus) and a small ITA in the male palp (Figs 5B, 5E), which is absent in A. loxodontillus (see Salgado & Ruiz 2017: figs 26B, 26D). Also, males of A. cornipalpis sp. nov. differ from those of all other species of Amphidraus by having a tubercle placed on proximal dorso-retrolateral portion of the cymbium (black arrows in Figs 2 C–F, 5A–B, 5E, 6C) (present also in Yacuitella nana Galiano, 1999). Females of A. cornipalpis sp. nov. are similar to those of Y. nana by the arrangement of copulatory ducts and spermathecae in the epigyne, but differ from that species by having more separate copulatory openings, longer copulatory ducts and no tubercle on the epigynal plate (Fig. 5F), which is medially placed in Y. nana (see Galiano 1999: figs 12–14). Description. Male holotype (MPEG 35014). Total length: 3.33. Carapace 1.78 long, 1.23 wide and 0.89 high. Ocular quadrangle 0.83 long. Anterior eye row 1.25 wide, posterior 1.13 wide. Legs 4312. Length of leg: I 2.65 (0.83 + 1.00 + 0.82); II 2.54 (0.81 + 0.93 + 0.80); III 3.12 (1.01 + 1.09 + 1.02); IV 3.40 (0.97 + 1.19 + 1.24). Palp (Figs 2 C–F, 3A, 5A–E, 6A–E): femur with large and low bump on median-ventral portion (Fig. 5C); patella with no modifications; tibia with a prolateral rounded expansion and a ventro-distal depression (Figs 2 D–F, 5A, 5E, 6A); large RvTA with acute tip (Figs 2D, 5B, 6C); short, poorly-sclerotized ITA retrolaterally projected (Figs 2F, 5E, 6C); cymbium oval (Figs 2F, 5E), with conductor (cc) wider than long with sinuous proximal border (Figs 2E, 6 A–B); tegulum with slender lobe curved to prolateral side (Figs 2C, 3A, 5A, 5D); embolus shaft (e) with tip strongly curved to retrolateral side (Figs 2C, 3A, 5A); embolic filament (ef) longer than embolus shaft (Figs 3A, 5A, 5D). Color in alcohol (Figs 1, 2 A–B): cephalic area black; thoracic area light brown with a black procurved arc; chelicera light brown; palp light brown, with black mark ventrally on femur and with dark brown cymbium; mouthparts and sternum light brown; abdomen dorsally and ventrally light brown variegated with dark brown; legs light brown with a distal black ring on metatarsi III and two black rings on metatarsi IV, one proximal and another distal. Female paratype (MPEG 35015). Total length: 3.77. Carapace 1.66 long, 1.15 wide and 0.81 high. Ocular quadrangle 0.80 long. Anterior eye row 1.13 wide, posterior 1.00 wide. Legs 4312. Length of leg: I 2.54 (0.83 + 1.00 + 0.71); II 2.25 (0.73 + 0.88 + 0.64); III 3.08 (1.05 + 1.05 + 0.98); IV 3.55 (1.08 + 1.23 + 1.24). Epigyne/vulva (Figs 4C, 5F): epigynal plate with posterior border slightly bilobed; copulatory openings separated by approximately two diameters of copulatory ducts; long and convoluted copulatory ducts, forming a pair of rounded masses with spermathecae; oval spermathecae diagonally projected; fertilization ducts anteriorly placed and laterally projected. Color in alcohol (Figs 4 A–B): cephalic area black; thoracic area dorso-laterally dark brown and centrally light brown; abdomen dorsally and laterally variegated with brown; ventrally pale; pale legs with black spots, being more intense on metatarsi III and IV (same pattern as in male). Distribution. Known from the states of Pernambuco and Piauí (Brazil) (Fig. 14).Published as part of Salgado, Alexandre & Ruiz, Gustavo R.

Amphidraus boomerang Salgado & Ruiz 2019, sp. nov.
No full textAmphidraus boomerang sp. nov. Figs 7–8, 14 Type material. Holotype: Ƌ from Fazenda Nazareth, [4°45'03.4"S; 42°35'14.2"W], José de Freitas, Piauí, Brazil, 31.I.2004, V.O. Costa leg. (MPEG 9881). Etymology. The specific epithet is a noun in apposition and refers to embolic disc, boomerang-shaped (Figs 7C, 8A). Diagnosis. A. boomerang sp. nov. differs from all Amphidraus species by having the embolic disc boomerangshaped, due its expanded retrolateral border (Figs 7C, 8A). The retrolateral triangular lamella on the embolus shaft of A. boomerang sp. nov. is also present in A. argentinensis Galiano, 1997, near the emergence point of the embolic filament (see Galiano 1997: figs 9–10). A. boomerang sp. nov. can be distinguished from A. argentinensis by shape of the RvTA, large and with a ventral lobe in A. argentinensis (Galiano 1997: fig. 11) and reduced in A. boomerang sp. nov. (Fig. 8B). Description. Male holotype (MPEG 9881). Total length: 3.08. Carapace 1.62 long, 1.07 wide and 0.85 high. Ocular quadrangle 0.83 long. Anterior eye row 1.17 wide, posterior 0.98 wide. Legs 4312. Length of leg: I 2.65 (0.82 + 1.01 + 0.82); II 2.49 (0.80 + 0.91 + 0.78); III 3.15 (0.99 + 1.05 + 1.11); IV 3.47 (1.02 + 1.21 + 1.24). Palp (Figs 7 C–F, 8A–D): femur and patella with no modifications; short RvTA with two apical teeth (Figs 7D, 8B); straight RTA with the same length of tibia and with membranous external border (Figs 7D, 7F, 8B, 8D); cymbium oval, with proximal dorso-prolateral portion prominent (Figs 7F, 8D); tegulum with thick and straight lobe (Figs 7C, 8A); embolic disc with a process with acute tip (dPED) placed on the median distal portion and projected to prolateral side, with a ventral process (vPED) ventrally projected and with a proximal process (pPED) projected to proximal side, hidden under the tegulum (Figs 7 C–E, 8A, 8C); embolus shaft (e) with tip curved to retrolateral side and with two processes: a triangular lamella placed at the middle of retrolateral border and a rounded basal process (Figs 7C, 8A); embolic filament (ef) approximately 1/2 the length of embolus shaft (Figs 7C, 8A). Color in alcohol (Figs 7 A–B): cephalic area black; thoracic area brown with light brown longitudinal stripe; abdomen dorsally variegated with light brown and with longitudinal stripe of white setae; ventrally pale; pale legs. Female. Unknown. Distribution. Known only from the type locality (state of Piauí) (Fig. 14).Published as part of Salgado, Alexandre & Ruiz, Gustavo R.
