Figs. 112−113 View FIGURES 106 – 113
Type material. Male holotype and male paratype from Rio Samiria [74°17'W, 4°42'S], Loreto, Peru, 1990, T. Erwin coll., deposited in USNM.
Etymology. The specific name is a noun in apposition referring to the “ Urarina ”, indigenous people from Peruvian Amazon basin (Loreto). The ethnonym “ Urarina ” may derive from Quechua: “uray” meaning below, and “rina” referring to “runa”, or people.
Diagnosis. Males of Strotarchus urarina n. sp. resemble those of S. silvae n. sp. by the U-shaped proximal fold of reservoir, the embolar base visible retrolaterally in ventral view of unexpanded bulb and by the embolar apices arising retrolaterally but is readly recognised by the shorter cymbium and the larger tegulum ( Figs. 112, 113 View FIGURES 106 – 113 ).
Description. Male (Holotype). Carapace orange, margins paler. Chelicerae red brown. Endites and labium red brown with white apices. Sternum yellow, margins brown. Legs orange, with bases of articles darker. Abdomen and spinnerets light gray. Total length 6.70. Carapace 2.70 long, 2.30 wide. Eye diameters: AME 0.20, ALE 0.18, PME 0.20, PLE 0.20. Chelicerae with 3 promarginal teeth, the median largest, and 2 retromarginal teeth, separated by more than seven times their width. Leg measurements: femur I 2.70/ II 2.30/ III 2.00/ IV 2.40. Leg spination: I—femur d1-1-0, p0-1-1, r0-1-1; tibia d0-1m-0, p1-1-0, r1-1-0, v2-2 -0; metatarsus d0-1m-0, p1-1-2, r1-1-2, v2-2 -2. II—femur d1-1-0, p0-1-1, r0-1-1-1; tibia d0-1m-0, p1-1-0, r1-1-0, v2-2 -0; metatarsus d0-1m-0, p1-1-2, r1-1-2, v2- 2 -2. III—femur d1-1-1, p0-1-1-1, r0-0-1; tibia d0-1m-0, p1-1-0, r1-1-0, v1 p-1p-0; metatarsus d0-1m-0, p1-1-2, r1- 1-2, v2-2 - 1m. IV—femur d1-1-0, p0-0-1, r0-0-1; tibia d0, p1-1-0, r1-1-0, v1 p-1p-0; metatarsus d0- 0-1m, p1-1-2, r1-1-2, v2-2 -1m-2. Palpal tibiae thin, short, with one fourth of cymbium length; RTA square; ppRTA small, tip rounded, laRTA absent. Tegulum sub-oval; proximal fold of reservoir thick, u-shaped; TA inconspicuous; EB visible ventrally as a retrolateral triangular area between tegulum and BEF in unexpanded bulb; BEF wide, traversing apical portion of tegulum but obliquely displaced; EP small, covered by BEF in both ventral and retrolateral views; EA arising retrolaterally ( Figs. 112, 113 View FIGURES 106 – 113 ).
Variation. Two males: total length 5.50−6.70; carapace 2.40−2.70; femur I 2.30−2.70.
Distribution. Peruvian Amazonia.
Other material examined. None.
