SOESILADEEPAKIUS BIARMATUS   SP. NOV.

( FIGS 33–37 View Figure 33–37 , 50 View Figure 47–52 )

Type: Holotype: male from Acampamento Mutum , Juruti, Pará, Brazil, coordinates -2.603111, -56.210083, 4.viii.2004, D.F. Candiani & D.R. Santos- Souza, deposited in MPEG 8841 GoogleMaps   . Paratypes: Pará, Juruti: one female, same data ( MPEG 8849) GoogleMaps   ; one female (Platô Capiranga, coordinates -2.472806, -56.208167), 9.iii.2006, D.R. Santos & S.C. Dias ( IBSP 160864, ex-MPEG 9150) GoogleMaps   .

Etymology: The specific epithet is a Latin adjective referring to the two developed apophyses on each male palpal femur.

Diagnosis: This species can be distinguished from the others by the two conical apophyses at the base of the male palpal femur ( Fig. 35 View Figure 33–37 ).

Description: Male (MPEG 8841). Total length: 2.51. Carapace light brown, 1.28 long, 0.92 wide, 0.45 high, lateral borders posteriorly dark brown. Ocular quadrangle 0.78 long. Anterior eye row 1.03 wide, posterior 0.95 wide. Clypeus densely covered with white long scales. Chelicera yellow. Endite, labium, and sternum yellow. Palpal femur dorsally covered by a fringe of long white scales, ventrally with two keels (similarly to that of S. gasnieri   sp. nov., Fig. 50 View Figure 47–52 ), retrolaterally with two proximal apophyses; tibia with a ventral projection, no developed RTA; cymbium with a prolateral proximal projection; tegulum elongate, with a prolateral, distal flap and a retrolateral, distal projection; embolus straight arising from the proximal tegulum, with two small apophyses on its base. Legs as in S. gasnieri   sp. nov. Abdomen yellow, with three transverse dark brown stripes, the middle one medially interrupted, totally covered with a light brown dorsal scutum; ventrally yellow, dark brown close to spinnerets. Scale spots on abdomen as in S. gasnieri   sp. nov., except for the anterior pair, elongate. Spinnerets yellow, variegated with dark brown.

Female (MPEG 8849). Total length: 2.79. Carapace light brown, 1.45 long, 1.06 wide, 0.50 high. Ocular quadrangle 0.81 long. Anterior eye row 1.12 wide, posterior 1.03 wide. Clypeus glabrous. Chelicera as in male. Endite, labium, and sternum yellow. Palp yellow, variegated with dark brown. Tarsus with r1d1r-2 spines. Legs as in S. gasnieri   sp. nov., but leg I prolaterally and retrolaterally dark brown. Abdomen yellow, three dorsal dark brown transverse stripes very developed, anterior pair fused medially. No tufts of white scales. Epigyne similar to that described for S. gasnieri   sp. nov., except for the wider copulation ducts and tighter anterior pocket ( Figs 36– 37 View Figure 33–37 ). Spinnerets as in male.
