Attus simoni Taczanowski, 1871: 63  .

Salticus simoni  : considered a nomen dubium by Roewer 1955; followed by WSCAbout WSC 2016. non Salticus simonii Kulczyński, 1907  [synonymized with Salticus unciger (Simon, 1868)  by Prószyński 1984].

Types: lectotype (here designated): male from Uaçá River , Amapá, Brazil, M. Jelski, deposited in PANAbout PAN, examined (and two mismatched female paralectotypes). 

Additional material examined. BRAZIL: Pará: Belém , 2 ♂ and 3 ♀  , Ilha Grande (1.49°S 48.4°W), 2013, A. Sobrinho & G.R.S. Ruiz leg. ( MPEGAbout MPEG 31790–31794View Materials)GoogleMaps  ; 1 ♂, Campus of the Universidade Federal do Pará, 2014, G.R.S. Ruiz et al. (specimen # BRAAbout BRA 14-2939View Materials)  .

Diagnosis. Males of this species can be recognized by having the embolus extending straight distally and then forming an angle at its middle ( Fig. 11View FIGURES 10 – 16) (no abrupt angle in E. igapo  sp. nov.; see Fig. 44View FIGURES 44 – 49). Also, males of E. simoni  have smaller terminal apophysis and stronger RTA ( Fig. 11View FIGURES 10 – 16). Females of E. simoni  have their copulatory openings fused with anterior guides, the spermathecae are smaller and the dorsal coupling pocket is centralized ( Figs 9View FIGURES 5 – 9, 15– 16View FIGURES 10 – 16).

Description. Male (fresh specimen from Belém, MPEGAbout MPEG 31790): Total length: 5.68. Color pattern as described for the genus ( Fig. 5View FIGURES 5 – 9). Carapace 2.84 long, 2.00 wide, 1.46 high. Ocular quadrangle 1.46 long. Anterior eye row 1.92 wide and posterior 1.77 wide. Palp as described for the genus ( Figs 6–7View FIGURES 5 – 9, 10–14View FIGURES 10 – 16, 17–24View FIGURES 17 – 20View FIGURES 21 – 24). Leg formula: 4312. Length of femur: I 1.46, II 1.39, III 1.70, IV 1.61; patella + tibia: I 1.92, II 1.70, III 1.78, IV 1.75; metatarsus + tarsus: I 1.34, II 1.32, III 1.80, IV 1.94. Leg macrosetae: femur I=II d1-1-1, p2di, r0; III d1-1-1, p0-1-2, r1di; IV d1- 1-1, p1di, r1di; patella I=II p1, r0; III=IV p1, r1; tibia I=II p1-1-1, r0, v2-1 r-2; III p1-1-1, r2-1-1, v1 p-0-2; IV p1-1- 1, r1-1-1, v1 p-0-2; metatarsus I=II v2-2; III p1-0-2, r1-1-2, v1 p-1r-2; IV p1-1-2, r2-1-2, v1 p-1r-2.

Female (fresh specimen from Belém, MPEGAbout MPEG 31792): Total length: 6.14. Color pattern as described for the genus ( Fig. 8View FIGURES 5 – 9). Carapace 2.92 long, 1.92 wide, 1.46 high. Ocular quadrangle 1.38 long. Anterior eye row 1.92 wide and posterior 1.84 wide. Leg formula: 4312. Length of femur: I 1.46, II 1.39, III 1.82, IV 1.73; patella + tibia: I 1.94, II 1.73, III 1.97, IV 2.02; metatarsus + tarsus: I 1.25, II 1.18, III 1.80, IV 1.99. Leg macrosetae: femur I d1-1- 1, p1di, r0; II=III d1-1-1, p2di, r0; IV d1-1-1, p0, r1di; patella I=II 0; III=IV p1, r1; tibia I p0-1-1, r0, v2-1 r-2; II p1- 1-1, r0, v2-1 r-2; III=IV p1-1-1, r1-1-1, v1 p-0-2; metatarsus I=II v2-2; III=IV p1-0-2, r1-1-2, v1 p-1r-2. Epigyne as described for the genus ( Figs 9View FIGURES 5 – 9, 15–16View FIGURES 10 – 16).

Biology. Fresh specimens were found hunting on the ground near the water on an island that is flooded from time to time when the higher tides meet the rainy season in Northern Brazil. The ground is rich in fine sediments and is normally constantly wet. Specimens used in the descriptions were collected from among wandering juvenile crabs ( Armases  sp.). The species was not found in nearby drier areas, rendering obvious its preference for wet habitats, where it is the dominant species of jumping spider on the ground. This species seems to be associated to the “várzea”, the white water flooded areas in the Amazon.

Distribution. Known only from the states of Amapá and Pará, Brazil.
