03F987C08A7301703AEE8FD5FB9C4F9A.taxon	etymology	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. 3 A).	en	Salgado, Alexandre, Ruiz, Gustavo R. S. (2019): Seven new species of Amphidraus Simon, 1900 (Araneae: Salticidae: Euophryini). Zootaxa 4563 (3): 451-481, DOI: 10.11646/zootaxa.4563.3.3
03F987C08A7301703AEE8FD5FB9C4F9A.taxon	diagnosis	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 2 C, 3 A, 5 A, 5 D, 6 D – E), whereas in A. loxodontillus the dPED is short and rounded (Fig. 3 B; see also Salgado & Ruiz 2017: fig. 26 C). 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 5 B, 5 E), which is absent in A. loxodontillus (see Salgado & Ruiz 2017: figs 26 B, 26 D). 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, 5 A – B, 5 E, 6 C) (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. 5 F), which is medially placed in Y. nana (see Galiano 1999: figs 12 – 14).	en	Salgado, Alexandre, Ruiz, Gustavo R.

03F987C08A7101743AEE8D0CFBCF4D6A.taxon	diagnosis	Diagnosis. A. boomerang sp. nov. differs from all Amphidraus species by having the embolic disc boomerangshaped, due its expanded retrolateral border (Figs 7 C, 8 A). 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. 8 B).	en	Salgado, Alexandre, Ruiz, Gustavo R. S. (2019): Seven new species of Amphidraus Simon, 1900 (Araneae: Salticidae: Euophryini). Zootaxa 4563 (3): 451-481, DOI: 10.11646/zootaxa.4563.3.3

Anterior eye row 1.48 wide, posterior 1.19 wide. Legs 4312. Length of legs: I 3.79 (1.22 + 1.43 + 1.14); II 3.62 (1.19 + 1.28 + 1.15); III 4.46 (1.40 + 1.45 + 1.61); IV 4.75 (1.39 + 1.61 + 1.75). Palp (Figs 9 C – F, 10 A – E): femur and patella with no modifications; RvTA with two short branches, the more ventral branch is reduced and rounded, and the more dorsal branch is larger, with acute tip (Figs 9 D, 10 D); RTA with wide base, shorter than the tibia and with acute tip (Figs 9 D, 10 D – E); cymbium oval (Fig. 10 E); tegulum with stout lobe curved to prolateral side (Figs 9 C, 9 F, 10 A); embolic disc with three processes very close together on its distal portion: two short and rounded distal process (dPED) and one short and triangular ventral process (vPED) (Figs 9 D, 9 F, 10 A – B, 10 D); embolic filament (ef) very short, approximately 1 / 5 the length of embolus shaft (Figs 9 F, 10 A – B).

Female. Unknown. Note. The RvTA was interpreted herein as an apophysis with two branches (Figs 9 D, 10 D). However, in other Amphidraus species, such as A. araripe sp. nov., these branches are not fused and therefore interpreted as two distinct apophyses: one RvTA and one ITA (Figs 11 F, 13 B). The processes placed proximally on embolic disc and herein named as the pPED in A. sacrificatus sp. nov. and A. boomerang sp. nov. (Figs 7 C, 8 A) are possibly homologous. However, in A. sacrificatus sp. nov. it is linked to a heart-shaped membrane [Figs 9 C, 9 F (white arrow), 10 A – B]. The homologies of all these structures across the genus need to be tested in future studies.	en	Salgado, Alexandre, Ruiz, Gustavo R. S.

03F987C08A7B017C3AEE8DA0FBA94A95.taxon	diagnosis	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 11 D, 13 B; see Salgado & Ruiz 2017: fig. 8 C) 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. 11 E; see also Salgado & Ruiz 2017: fig. 8 D) and the RTA is linked to an inflated membrane (Figs 11 E – G, 13 B – C; see Salgado & Ruiz: figs 8 B, 8 D). These species also have an embolic disc with a distal process projected to prolateral side and a ventral process projected to retrolateral side (Figs 11 C, 13 A; see Salgado & Ruiz 2017: fig. 8 C). However, A. araripe sp. nov. can be distinguished by having the RvTA and ITA more separated from each other (Figs 11 F, 13 B), whereas these are almost fused in A. pulvinus (see Salgado & Ruiz 2017: fig. 8 D). In addition, A. araripe sp. nov. has a vPED placed near the distal processes (Figs 11 C, 13 A), whereas in A. pulvinus the vPED is placed on the prolateral border of embolic disc (see Salgado & Ruiz 2017: fig. 8 C). 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 12 C, 13 D, 16 D, 17 D). 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 13 D, 17 D).	en	Salgado, Alexandre, Ruiz, Gustavo R.

03F987C08A7C01633AEE8C24FB5E4DFE.taxon	diagnosis	Diagnosis. Among all species of Amphidraus, the male of A. manauara sp. nov. is most similar to that of A. caxiuanan Salgado & Ruiz, 2017 by having the embolic disc with a long, prolaterally projected distal process (dPED) with rounded tip, and a short, ventrally projected ventral process (vPED) (Figs 15 C, 17 A, 18 B); also by having the tibial apophyses with similar pattern (RvTA short and rounded and the RTA is curved on its basal portion and points to apex of cymbium; Figs 15 D, 17 C, 19 G); and by having the cymbium with the proximal, dorso-prolateral portion prominent and one cavity placed on proximal, dorso-retrolateral portion (Figs 17 B, 19 D). However, the male of A. manauara sp. nov. can be distinguished by having the embolus shaft and embolic filament shorter in proportion to embolic disc (Figs 19 A, 19 C), by having shorter proximal, dorso-prolateral projection of cymbium (Figs 19 B, 19 D) and shorter RTA (Figs 19 E – G). The female of A. caxiuanan is unknown, but among Amphidraus females currently known, A. manaura sp nov. is most similar to A. complexus Zhang & Maddison, 2012 by having short copulatory ducts, and the copulatory openings far apart from the posterior border of the epigyne (Figs 16 D, 17 D); see Zhang & Maddison 2012: figs 5 – 6). However, the female of A. manauara sp. nov. can be distinguished by having glands associated with the copulatory openings, and longer copulatory ducts (Figs 16 C – D, 17 D).	en	Salgado, Alexandre, Ruiz, Gustavo R.

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 17 A, 19 C); 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 17 B, 19 B, 19 D). However, Amphidraus caxiuanan can be distinguished by having a longer proximal dorso-prolateral projection of cymbium (Figs 19 B, 19 D) 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 19 A, 19 C). The female of A. caxiuanan is still unknown.	en	Salgado, Alexandre, Ruiz, Gustavo R. S. (2019): Seven new species of Amphidraus Simon, 1900 (Araneae: Salticidae: Euophryini).

03F987C08A6301633AEE8AD1FB7E4AFB.taxon	description	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, 18 F – H, 19 C – D, 19 F – G): the RTA has a slight (Figs 18 G, 19 F) or accentuated curvature (Figs 18 C, 19 G); the dorso-prolateral, proximal cymbial projection varies in length (Figs 18 D, 18 H); RTA length is also variable (Figs 18 C – D, 18 G – H, 19 F – 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).	en	Salgado, Alexandre, Ruiz, Gustavo R. S.

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.

03F987C08A6501683AEE8C24FC3B4D36.taxon	diagnosis	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 21 D, 26 A, 26 C, 27 A); also, by having the RvTA pointing ventrally, with projections on its border (Figs 21 F, 22 B, 26 G). 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 26 G, 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 21 F, 22 B, 26 H). 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 24 D, 25 D, 27 E). 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. 24 F), whereas they connect to the outer border of the spermathecae in A. draconitupan (Fig. 25 D).	en	Salgado, Alexandre, Ruiz, Gustavo R.

03F987C08A6501683AEE8C24FC3B4D36.taxon	description	Description. See Salgado & Ruiz (2017). Variation. Among the males examined, we observed the following variation in palpal structures (Figs 26 A – D, 26 G): 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. 26 G; see Salgado & Ruiz 2017: figs 23 B, 24 B, 24 D). 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 22 A, 25 A, 26 A, 27 A). Moreover, males also have pockets on outer faces of chelicerae (Figs 28 A – C, 29 A – B), of unknown use.	en	Salgado, Alexandre, Ruiz, Gustavo R. S.
